Stable hydraulic pie driving equipment for buildings

Abstract

The invention provides stable hydraulic piling equipment for construction, which includes a hammer head mechanism of a hydraulic pile driver and fixing bolts; the top of the hammer head mechanism of the hydraulic pile driver is fixedly connected with an oil cylinder piston rod, and the bottom of the hammer head mechanism of the hydraulic pile driver contacts a hammer pad, and Below the hammer pad is a pile; the axial center position at the bottom of the upper platen is fixed with the buffer protection pad that is consistent with the diameter of the inner ring of the annular pressing block through two fixed bolts; the axial center position at the top of the lower platen is The buffer protection pad which is consistent with the diameter of the inner ring of the annular pressure block is also fixedly installed by two said fixing bolts. The number of annular briquetting blocks is not limited to eight groups, and can be adjusted by increasing / decreasing. By changing the number of annular briquetting blocks, the height of the hollow chamber can be changed, which is conducive to the impact of the impact head. The bottom end surface of the hollow chamber is separated, and then the top surface of the hollow chamber gives a greater impact force to the steel wire mesh sleeve, so as to improve the efficiency of piling.

Description

technical field [0001] The invention belongs to the technical field of pile machinery, in particular to stable hydraulic pile driving equipment for construction. Background technique [0002] The hydraulic piling hammer is a new type of engineering machinery developed to overcome the noise and pollution of the diesel hammer. It is widely used in the construction of pile foundations in bridges, industries, and buildings. In the pile hammer hammering system, the hammer head reciprocates up and down, strikes the hammer pad, and transmits the impact force to the pile. [0003] In the prior art, the head of the hydraulic piling hammer is a whole piece of forged steel processed into a cylindrical or cuboid shape. Since the work of the piling hammer mainly utilizes the gravitational potential energy of the hammer head, the weight of the hammer head is relatively large. The processing of the whole hammer head has special requirements on the bearing capacity of the machine tool, and...
