Problems solved by technology

However, most of the vibrating pile hammers are mechanical eccentric vibrating devices directly driven by the motor through the belt drive, which not only requires high vibration resistance of the motor, but also has a lot of noise and serious environmental pollution.
At the same time, because the machine often uses the top of the pile to clamp and apply the exciting force, the damage to the prefabricated pile is relatively large, and it is only suitable for steel pipe piles.

Embodiment Construction

[0015] Below in conjunction with accompanying drawing, specific embodiment of the present invention is described in further detail:

[0016] The hydraulic vibratory pile driver shown in the figure has a rectangular fuselage platform 1, and the fuselage platform 1 is the supporting body of all executive parts. Four jacking cylinders are installed vertically at the four corners of the fuselage platform 1, and the piston rod hinge of the jacking cylinder is connected with the longboat running mechanism 2 through the fork shaft trolley; the two sides of the fuselage platform 1 are hinged with four Support leg 8, the lower end of this support leg 8 links to each other with parts such as bearing pin and short boat running mechanism 6, can realize the horizontal and vertical walking and turning of whole pile driver by long boat running mechanism 2 and short boat running mechanism 6. The counterweight beam 5 and its counterweight are mounted on the legs 8 .

Abstract

The hydraulic vibrating pile driver has one platform supported by long boat, short boat and other parts and driven by them to walk; and there are pile driving beam, crane, electric control system and hydraulic control system mounted on the platform. There are pile driving oil cylinder mounted on the beam and hydraulic excitation mechanism driven by the hydraulic control system below the beam. The hydraulic excitation mechanism has upper part connected to the lower part of the piston rod in the pile driving oil cylinder and lower part connected to the hydraulic prefabricated-pipe holding mechanism. There are guide blocks fitted to the guide rails on the vertical beam in the four corners of both the hydraulic excitation mechanism and the hydraulic holding mechanism for the simultaneous motion of the two mechanisms. The pile driver has high efficiency, low noise and no damage to pile.

Description

technical field [0001] The invention relates to pile-pressing equipment used in foundation construction of urban construction projects, in particular to a hydraulic vibration pile-pressing machine. Background technique [0002] At present, in the foundation construction of urban construction projects, the widely used prefabricated pile pile pressing equipment mainly includes hydraulic static pile driver and mechanical vibratory pile driver. The hydraulic static pile driver uses hydraulic static force to press the prefabricated pile into the soil layer in sections, and its advantages are no vibration, low noise and no pollution. However, it has high requirements on the frame structure, many counterweights, and large material consumption, which makes it consume a large amount of resources and high transition costs. The entire machine's transition, assembly, transportation and work efficiency are low, especially in construction. The medium prefabricated pil...
