How to drive hydraulic pile hammer? As for the piling method of the hydraulic piling hammer, as a piling hammer manufacturer, let Xiaobian take you to find out! Hydraulic power station, piping system, oil cooling system, electronic control system, control system, striking system can be used for upgrading and upgrading of hydraulic power hammer. Through improvement, the technical parameters of the full hydraulic free forging hammer are consistent with the whole machine. It is suggested to directly change the original hydraulic die forging hammer to a program-controlled full hydraulic die forging hammer. Of course, in order to save costs, the full hydraulic free forging hammer can also be transformed into a follow-up control full-hydraulic die forging hammer, compared with the program-controlled full-hydraulic die forging hammer with follow-up control. When hitting, it can realize the hammer action at any position, and the hitting is highly random. It is especially suitable for occasions with high requirements for auxiliary processes such as rolling extrusion and elongation and complicated process changes. However, the consistency of forging is worse than that of the program-controlled hammer, and the forging effect is highly dependent on the skill of the operator.

Diesel engine hammers are divided into guide rod type and barrel type according to their structure. The guide rod type diesel engine hammer uses the plunger pump as the hammer seat to press on the pile cap, and uses the cylinder as the high chrome alloy hammer head to lift along the two guide rods.When the foundation is piling, the diesel hammer manufacturer first hoists the pile to the pile frame and the gantry for hoisting, and then puts the diesel hammer on the top of the pile, lowers the lifting hook to hang the cylinder, and loosens the lifting hook to let the cylinder fall into the sleeve. The plunger pump expands and shrinks the closed gas in the cylinder, and the cylinder descends again until the pressure pin outside the engine cylinder pushes the remote rod of the high-pressure oil pump on the hammer seat, and the high-pressure oil pump sprays the oil mist into the tank body. The oil mist hits the high-temperature vapor around the ignition point and immediately deflagrates. The bouncing force moves down the pile and pushes it upward to warm the cylinder. When the cylinder falls along the guide rod again, it starts to impact again. circulatory system.The cylinder type diesel engine hammer uses the cylinder as the hammer seat, and immediately uses the extended cylinder liner inner cavity for guidance, eliminating the need for two guide rods. The plunger pump is a high-chromium alloy hammer head, which can exercise up, down, left and right in the cylinder. . When the foundation is piling, the pile cap under the hammer seat is pressed on the top of the pile, and the plunger pump is raised with a lifting hook, and then the downward impact is decoupled to reduce the gas enclosed in the cylinder. And carry out oil pump, outbreak, impact, ventilation, etc. The whole process of work. The diesel engine hammer is started by a compression ignition diesel engine, so it is necessary to ensure that the closed gas in the cylinder exceeds the necessary compression ratio. If the reduction amount is insufficient and the detonating tube cannot be ignited, it is necessary to use the lifting hook to hang the high-chromium alloy hammer several times to decouple the impact and start it. The hammer seat of the diesel engine hammer is equipped with a fuel injection pump, an automobile fuel tank, a water cooling water storage tank and a pile cap. The subject movement gap between the plunger pump and the cylinder liner is sealed with a ductile plunger pump ring.

The price of a full hydraulic electro-hydraulic hammer is about 1 million yuan or 2 million yuan each. The price of full hydraulic electro-hydraulic hammer is affected by brand, category, specification, market and other brands. Before choosing to buy, it is necessary to understand and compare multiple aspects. The full hydraulic electro-hydraulic hammer is a substitute for the traditional electro-hydraulic hammer, and it is a new type of forging equipment that is more energy-saving and environmentally friendly. The working principle is similar to that of the electro-hydraulic hammer. After the improvement, the striking frequency can be increased, the oil temperature can be reduced, the service life can be prolonged, the quality of the forgings can be improved, and a lot of energy can be saved. Hydraulic hammer belongs to impact pile hammer, which can be divided into single-acting type and double-acting type according to its structure and working principle. The so-called single-acting type means that the impact hammer core is quickly released to a predetermined height by a hydraulic device, and the impact hammer core falls freely. Double-acting type means that the impact hammer core is lifted to a predetermined height by a hydraulic device, and the acceleration energy is obtained from the hydraulic system to increase the impact speed. This also corresponds to the two piling theories. The single-acting hydraulic pile hammer corresponds to the light hammer theory. It has the characteristics of large hammer core weight, low impact speed and long hammering time. The pile hammer has a large penetration per strike, is suitable for pile types of various shapes and materials, and has a low damage rate, especially for concrete pipe piles. The double-acting hydraulic pile hammer corresponds to the light hammer and heavy hammer theory. It has the characteristics of low weight of hammer core, high impact speed and short action time of hammer pile. The impact energy is large, which is more suitable for steel piles.

The intelligent control system of hydraulic pile hammer adopts PLC control to realize automatic control of hydraulic system and electrical system, data display of piling process, emergency alarm, emergency stop and other functions, which improves the safety of the product. The use of high-energy storage, single-action, free-conversion dual-circuit hydraulic system can make the hammer body fall quickly, improve the striking ability of the pile hammer, and use motor drive instead of diesel engine drive, which eliminates the environmental pollution caused by diesel combustion and meets environmental protection requirements. The semi-closed shape structure reduces the overall weight of the pile hammer and achieves the purpose of energy saving. The hydraulic impactor can be powered by the pile driver or connected with a special power station, and there are a series of supporting power stations for users to choose. All electrical circuits and hydraulic systems can be easily operated using the control panel or remote control. The whole machine adopts the oil-closed mode. By adjusting the speed and oil pressure, the equipment is reliable and environmentally friendly, while taking into account the efficiency and safety. The striking energy and striking frequency are not affected by the reaction force of the foundation. It is completely dependent on the operator to control the striking process of the hydraulic pile hammer through the electronic program, which can avoid the phenomenon of sliding piles and realize the light strike action of the heavy hammer. The striking efficiency of the hydraulic pile hammer is higher than that of diesel oil. The hammer is many times higher. High kinetic energy, low hammer speed and low hammer stress.

What are the methods of driving a piling hammer? The method of driving with a pile hammer is to impact the pile head with a pile hammer. At the moment of the impact, the pile head is subjected to a large force, so that the pile gradually penetrates into the soil. How does it work? The piling hammer manufacturer introduces the following relevant information on the piling hammer driving method: There are four main types of piling hammers using the piling method: (1) The main features of the drop hammer: make the hammer fall freely and impact the pile head. This is an ancient piling machine with simple structure and convenient use. However, the penetration ability is small, the productivity is low, and the collision damage is large. Scope of application: mainly light wood piles; heavy and extra-heavy reinforced concrete piles; except for light drop hammers (0.5-0.75t), they are generally hammered by winches. (2) Diesel hammer Its working principle is similar to that of a two-stroke engine, and it is the most widely used pile hammer at present, but it is a big public nuisance and has been banned in the central areas of some cities in my country.Scope of application: Light duty for wood piles and steel sheet piles; heavy duty for reinforced concrete piles and steel pipe piles; not suitable for piling in hard or soft soil layers. (3) The main features of the steam hammer: It is a pile hammer that was initially used with steam and compressed air as the power. It was gradually eliminated after the development and use of the diesel hammer. However, due to the serious use of diesel hammer pollution, the steam hammer was used again. . Scope of application: suitable for driving various piles, easy to drive inclined piles; if compressed air is used, piles can be driven underwater; it can be used to pull piles. (4) Hydraulic hammer Main features: powered by hydraulic pressure, it has the advantages of high impact frequency, large impact skills and less pollution. However, the structure is complex, the cost is high, and the use and maintenance requirements are high. Scope of application: suitable for various soil layers and pile shapes; good inclined pile capacity; suitable for large-scale pile foundation projects with high precision requirements.

Since the working environment of the hydraulic hammer is generally poor, it is easy to cause failure. In order to eliminate hidden dangers and shorten the maintenance cycle, it is necessary to carry out daily and regular maintenance. 1. Routine maintenance. 1) Keep the vibrating hammer clean, and clean the oil, dust, rust and water on the hammer body and power station after each shift. 2) Check the fasteners frequently to keep the connection firm and reliable. 3) Each lubrication point should be lubricated according to the lubrication requirements. 4) The hydraulic oil in the oil tank should be kept at a normal level, and the oil temperature should be kept at a normal level. Always check the cleanliness of the oil and place contamination. 5) Always check whether there is water in the hydraulic oil tank. If the oil is emulsified, remove the water or replace the hydraulic oil immediately. 6) Always check whether the instrument is stable and ready for normal operation, otherwise it should be repaired or replaced. 7) Check the oil circuit system for oil leakage and deal with it in time. 8) Check whether the liquid level of diesel tank, fuel tank and cooling water tank is normal. If the liquid level is too low, please replenish it in time 2. Regular maintenance. Regularly clean the fuel tank and replace the hydraulic oil. During the break-in period, it works continuously for 500 hours, and the hydraulic oil is replaced once, the second time after three months, and the third time in September. The replacement time depends on the situation. 4) The hydraulic oil in the oil tank should be kept at a normal level, and the oil temperature should be kept at a normal level. Always check the cleanliness of the oil and place contamination.

What are the development trends and market conditions of the pile driver industry? According to reports, the consumption of pile drivers is closely related to downstream industries and the global economy. The growth rate of the pile driver industry may not continue as fast as there will always be some uncertainty in the global economy in the coming years. But what is certain is that the market prospect of pile driver is promising. Compared with the traditional pile driver, the foundation pile driver not only has the functions and functions of the traditional pile driver, but also has a wider application range and greater advantages compared with the traditional pile driver. The foundation pile driver tool belongs to the traditional industry and has its own industrial characteristics. Foundation pile driver tools are widely used. How basic pile driver tools are better recognized and trusted by users is also a product with certain functional characteristics. It is understood that the pile driver is mainly used in construction sites, bridges, roads, etc. It is an important construction machine and is widely used. The pile driver consists of pile hammer, pile frame and auxiliary equipment. The pile hammer is attached between two parallel vertical guide rods (often called a gantry) in front of the pile frame and is lifted with a hook. The pile frame is a steel structure tower with a winch behind it to lift the pile and pile hammer. There is a guide frame consisting of two guide rods in front of the pile frame, which controls the direction of the pile according to the design direction, so that the pile can enter the ground accurately. The basic technical parameters of the pile driver are the weight of the impact part, the impact force and the impact frequency. The basic technical parameters of the pile driver are the weight of the impact part, the impact force and the impact frequency. Pile hammers can be divided into drop hammers, steam hammers, diesel hammers, hydraulic hammers, etc. according to the power source of the movement. In recent years, a group of piling enterprises with strong independent innovation ability have come to the fore, and the domestic market occupies 95% of the domestic piling machinery products. With the intensification of competition in the domestic pile machinery market, less competitive enterprises will be merged or eliminated. Companies such as Sany Heavy Industry, Zoomlion, and Shanhe Intelligent will gradually become industry leaders. The Chinese pile driver industry market is expected to become standardized and concentrated in the coming years

With the development of my country's economy, piling hammer technology has made great progress. Under the situation of increasingly tense land use, some factories, houses or other facilities have to be built on weak foundations such as seaside and river beaches. Piling machinery, In particular, the piling hammer plays an increasingly important role in my country's economic construction. The energy transfer efficiency of the hydraulic piling hammer can reach 70%~95%, while the energy transfer efficiency of the diesel hammer pile driver is only 20%~30%. The hammer pile driver has excellent performance in reducing noise, vibration and noise. It is a diesel belt start, powered by oil pressure, and the hydraulic pressure can be adjusted according to the different soil conditions of the stratum to achieve appropriate impact force for piling. It is a new type of piling. Equipment, especially suitable for urban construction needs. Sometimes when piling on soft soil layers, the reaction force is too small and the compression amount is not enough to ignite and detonate.

Check the wire rope and all visible parts of the wire rope. When the wire rope has one of the following conditions, it should be replaced: a. The surface of the wire rope is worn or corroded, b. The steel wire rope loses its normal state (such as partial flattening, kinking, bending, cage distortion, extrusion of strands or wires, local increase in rope diameter, wavy shape, etc.). c. The wire rope reaches the number of broken wires in Table 2 within the pitch; d. The broken wires are concentrated in the rope length range or one strand whose diameter is less than 6 times of the wire rope diameter. Check the power unit, hydraulic system, and electrical system, and follow the instruction manual. Before the three piles are erected, the braking performance and connecting parts of the winch should be checked, and the erection operation procedures should be carried out according to the instructions. After the four-pile frame is running, each mechanism should run without load, and check the indicated value of each instrument. Pile guide rails should be greased as required. Check whether the fuel oil, lubricating oil, hydraulic oil and cooling water of the pile driver meet the requirements of the manual. The cooling water of water-cooled diesel hammer should be clean and soft water. Check the working condition of the diesel hammer hanger and lubricate it; when the working surface of the starting hook end is worn more than 10mm, it should be repaired or replaced as required. The screw plug at the cleaning hole of the cylinder hammer should be coated with graphite powder, and lubricating oil should not be used. Check the cushion of the diesel hammer. When the contact surface is less than 30% of the original total area, or when the distance between the cylinder flange and the bottom of the lower piston is greater than the value specified in the manual, the cushion should be replaced. Check the wear of the diesel hammer guide plate. When the wear of the guide surface is greater than 10mm, it should be repaired or replaced. Check the connection between the diesel hammer and the pile cap. After raising the diesel hammer, when the length of the piston under the cylinder hammer does not meet the value specified in the manual, the length of the connecting wire rope should be adjusted.

Diesel hammer has strong explosive force, large hammering energy, high work efficiency, longer hammering time than free-fall hammering time, relatively low hammering stress, automatic adjustment of impact distance (drop distance), and is more suitable for prefabricated square piles or pipe piles. Drum-type diesel piling hammers are now widely used, especially the drum-type diesel piling hammers produced in recent years. The gas supply throttle is divided into four gears, the first gear is small and the fourth gear is large. When piling is generally used 2-3 gears, the operator is easy to grasp, and the hammering energy is easy to estimate. The choice of a piling hammer is a complex issue with many factors to consider. The main indicators for measuring the rationality of piling hammer selection are: (1) It can ensure that the bearing capacity of the pile meets the design requirements; (2) The pile can sink into the design depth smoothly or basically smoothly; (3) The damage rate of pile driving can be controlled at about 1%, not more than 3%; (4) The penetration that meets the design requirements is 20-40mm/10 strokes; (5) The number of hammer blows for each pile should be within 1500 blows and not more than 2000-2500 blows.
