A pile clamp assembly

Abstract

The invention relates to a pile gripper assembly. The pile gripper assembly comprises a frame body, a clamping oil cylinder, a piston, a copper sleeve, a fixing sleeve, a movable tooth plate and a fixed tooth plate, wherein the frame body comprises a transverse part provided with a cavity and a longitudinal part which is integrally formed with the transverse part; the piston comprises a piston head and a piston rod; the piston head integrally formed with the piston rod is sleeved by an annular protruding part; the piston rod at the right end of the piston head penetrates through the copper sleeve; the right end of an end cap part, the annular protruding part and the left end of the piston head form a first closed chamber; the right end of the piston head, the annular protruding part, the piston rod and the left end of the fixing sleeve form a second closed chamber; a first oil way system and a second oil way system are arranged in the frame body and the clamping oil cylinder; the first oil way system communicates with the first closed chamber; and the second oil way system communicates with the second closed chamber. The pile gripper assembly is convenient to mount, simple and firm in structure, relatively light in weight and relatively low in cost, and belongs to the technical field of pile grippers in hydraulic vibration hammers.

Description

technical field [0001] The invention relates to the technical field of pile clamps in hydraulic vibratory hammers, in particular to a pile clamp assembly. Background technique [0002] Hydraulic vibratory hammer is a kind of piling machine developed rapidly at the end of the 20th century. It can carry out various pile types such as steel sheet piles, steel pipe piles, full casing piles, special-shaped piles, and thin-walled cylindrical piles. It has low construction noise and high speed. It is fast, multi-functional, adaptable to a wide range of geology, wide construction range, convenient transportation and environmental protection. The pile clamp assembly is generally installed directly under the hydraulic vibratory hammer, and is connected with the slide rail under the hydraulic vibratory hammer through the chute of the pile clamp assembly to realize left and right movement, clamping steel pipe piles of different sizes, and making the pile It vibrates up and down togethe...

AI Technical Summary

Problems solved by technology

At present, the frame body of the commonly used pile clamp assembly is mostly made of cast steel structure. The locking cylinder and the frame body are two separate parts, and there is no support at the movable tooth plate. The structure weight of this kind of pile clamp assembly is heavy, The production cost is high, the structure is complicated, and the installation is difficult, so that the overall structure is not strong enough, the durability is poor, the maintenance frequency is high, and there are no protective measures for the clamping cylinder, which greatly shortens the life of the clamping cylinder
