Pile hammer assembly and pile driver with pile hammer assembly

Abstract

The invention relates to a pile hammer assembly which comprises a pile gripper (1) used for clamping a prefabricated pile and a pile sinking device (2) directly or indirectly acting on the pile gripper (1). The pile hammer assembly is characterized by further comprising a telescopic assembly (3) and a pitching angle adjusting device (4); and the telescopic assembly (3) is used for driving the pilegripper (1) to be close to or far away from the prefabricated pile in the axial direction of the prefabricated pile to be clamped, the pitching angle adjusting device (4) is used for adjusting the pitching angle of the pile gripper (1), and the telescopic assembly (3) and the pitching angle adjusting device (4) are arranged above the pile gripper (1). The pile gripper of the pile hammer assemblyis telescopic, the pitching angle can be adjusted, and the pile hammer assembly can clamp the prefabricated pile more conveniently and quickly. The invention also relates to a pile driver with the pile hammer assembly.

Description

technical field [0001] The invention belongs to the technical field of pile machinery, and in particular relates to a pile hammer assembly for pile driving construction and a pile driver with the pile hammer assembly. Background technique [0002] Pile drivers are widely used in building construction, which can drive prefabricated piles into the ground to achieve the reinforcement of foundations, roadbeds and embankments. According to the piling method, it can be divided into the following types: 1. Pile drivers that use impact force to penetrate piles into the ground, such as drop hammer pile drivers, air hammer pile drivers, hydraulic hammer pile drivers, etc., have the disadvantage of high noise during piling; 2. The vibratory pile hammer pile driver uses high-frequency vibration to vibrate the pile body with high acceleration, and transmits the vertical vibration generated by the machine to the pile body, resulting in the change of the soil structure around the pile due ...

AI Technical Summary

Problems solved by technology

The problem is: this will cause great damage to the pile body, such as scratches, or even damage to the end of the pile. In addition, due to the heavy weight of the pile body, it is difficult for the crane to drag it in multiple directions during the alignment process, and the operation is difficult. , the work intensity is high; moreover, after the pile body is hoisted by the crane, there is a position deviation between the top of the pile body on the crane and the clamping end of the pile body of the pile driver, and the pile body is usually at a certain angle to the ground, which is also a vertical Accurate alignment between the clamping end set straight down and the pile body brings certain difficulties, which affects the convenience of pile clamping
