A concrete pile head crushing device

Abstract

The invention discloses a concrete pile head crushing device. The device comprises a machine body, a movable base and supporting arms, wherein the movable base is arranged at the bottom of the machinebody, rolling wheels are installed at four corners of the bottom of the movable base, and the supporting arms are welded on the two sides of the upper surface of the movable base; a rotating shaft ishorizontally arranged at the upper part of the machine body, and the machine body is characterized in that the left end of the rotating shaft is rotationally connected with the supporting arms on theleft side, and the right end of the rotating shaft penetrates through the supporting arms on the right side and extends to the right side of the machine body; and a first servo motor is arranged on the right upper portion of the machine body, the right end of the rotating shaft is welded with an output shaft of the first servo motor, the rotating shaft is provided with two first bevel gears withthe same size, an inner threaded pipe is vertically arranged below the rotating shaft, and the lower end of the inner threaded pipe is connected with a screw rod in a rotating mode. According to the device, the design is reasonable, the pile head which can be crushed is quickly realized, time and labor are saved, the construction difficulty is lowered, the life safety of constructors is guaranteed, and the device is suitable for popularization.

Description

technical field [0001] The invention relates to a concrete pile head crushing device. Background technique [0002] Since the pile foundation is the most commonly used form of foundation in the maintenance pile construction of large bridges, super-large bridges and subway foundation pits, and the number is huge, we usually clean the pile head concrete manually with small machines or with a crushing vibrating hammer. It is time-consuming, labor-intensive and labor-intensive to manually use pneumatic picks to cut and separate all the main reinforcement of the pile head, and the work efficiency is low, and the personal safety risk is high, there are many safety hazards, and the construction cost is high. In order to achieve the goal of liberating heavy physical labor and replacing dangerous working parts with machinery, while reducing construction costs and improving construction efficiency, on the basis of summarizing previous construction operations, a reinforced concrete pil...
