Novel shoveling device of drill bit of long spiral pile driver

Abstract

The invention discloses a novel shoveling device of a drill bit of a long spiral pile driver. The shoveling device comprises a gear box, the gear box is connected with a motor, a rotary table on the gear box is driven to rotate by the motor, a wire rope fixing rope is further arranged on the rotary table, and at least one installation hole for wire ropes to insert in is formed in the wire rope fixing tube; the length of the wire rope at least reaches the positions of spiral blades of the drill bit of the spiral pile driver. According to the novel shoveling device of the drill bit of the long spiral pile driver, only soil on the spiral blades is scrapped off when the spiral blades are in contact with adopted wire ropes with a certain degree of flexibility, and the wire ropes have a certaindegree, so that a certain degree of bending can be achieved, and the spiral blades are not damaged when the wire ropes are in contact with the spiral blades; the wire ropes are installed through the wire rope fixing tube, and the wire ropes can be adjusted according to the distance between the wire wire ropes and the drill bit of the spiral pile driver.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a novel long screw pile drill bit soil cutter. Background technique [0002] Spiral pile driver is a commonly used piling and foundation tool in construction engineering. During the working process of the spiral pile driver, after the drill pipe is drilled into the ground to a certain depth, if the drill pipe is lifted upward, there will usually be a lot of sticking on the helical blade of the drill pipe. The mud not only affects the work progress and drilling quality of the next drilling, but also needs to spend manpower and time to complete the cleaning of the mud on the drill pipe. [0003] In the Chinese patent document CN205955651U, a CFG pile long screw piling machine mud scraping device is disclosed, which solves the potential safety hazard of soil falling when the existing long screw pile driver is working, and the time-consuming and laborious cleaning of the soil ...

AI Technical Summary

Problems solved by technology

But the disadvantages are also obvious. In the actual application process, since the arc-shaped scraper is hard, when the upward rotation speed of the screw pile driver is too high, the scraper will contact the spiral blade, and the scraper will be blocked. Driven to move upwards, destroying the fixed connection state of the mud scraper, and the mud scraper will scratch the spiral blade
