Supporting foot structure of the pipe unloader

Abstract

The invention relates to a supporting leg structure for a tube disassembly machine. The structure comprises a supporting leg fixedly connected onto a supporting base, a supporting column is arranged on the lower surface of the supporting leg, a threaded hole passing through the lower surface is formed in the supporting leg, an inverted-T-shaped structure is arranged on the supporting column, a column body of the supporting column is in spiral connection with the threaded hole, a connection block is arranged at the root of the threaded hole, and inner springs are arranged between the connection block and the upper end of the column. Cushioning space is formed between the lower end of the supporting leg and a beam of the supporting column, and outer springs are arranged in the cushioning space. By means of the structure, internal cross and vertical tensioning between the supporting leg and the supporting column is achieved through the cross springs, and accordingly, the internal spiral connection stability is improved, and deformation is reduced; the external vertical tensioning between the supporting column and the supporting leg is achieved through the outer springs, so that the vertical support stability is further improved; the structure is simple, convenient to mount and high in support stability.

Description

technical field [0001] The invention relates to the field of geological exploration equipment, in particular to a pipe unwinding machine. Background technique [0002] The pipe unwinding machine is a kind of machine used for unscrewing and unloading drill pipes when lifting and unloading drilling tools in geological drilling. It can replace manpower to unscrew and unload the drill pipe, reduce the labor intensity of workers, and improve the efficiency of lifting work. The drill pipe is composed of multiple sections, and the axial alignment between two adjacent sections must be ensured when unloading the pipe, otherwise the resistance of unloading the pipe is relatively large, which will affect the drill pipe. The pipe unloading machine clamps the drill pipe through two unloading claws, and unscrews the drill pipe when the unloading claws rotate. Therefore, it is very important to ensure the stability of the pipe unloader when it is working, and the stability depends on the...

Problems solved by technology

[0003] The support seat in the prior art is fixed on the bottom of the pipe unloading machine. The support seat consists of two parts connected up and down. After a long time, the two parts are easily deformed, and the relative position changes, which leads to the unbalance of the pipe unloading machine, thereby causing damage to the pipe unloading operation. influences
