Supporting device for coal mine drill pipe threading

Abstract

The invention discloses a supporting device suitable for coal mine drill pipe threading. The supporting device comprises liftable hydraulic stand columns. A supporting platform is arranged at the upper ends of the hydraulic stand columns, a drill pipe sleeve is arranged on the supporting platform, and a universal wheel convenient for travelling is arranged at the bottom end of each hydraulic stand column. By the adopted structure, due to the hydraulic stand columns and the supporting platform arranged at the upper ends thereof, the requirement for supporting a drill pipe can be met, and the hydraulic stand columns can be lowered during operation for the convenience of operation; the universal wheels convenient for travelling are arranged at the bottom ends of the hydraulic stand columns, so that moving and travelling of the supporting device can be facilitated; a pull rod is arranged on one side of the supporting platform, so that the supporting device can be used as a moving trolley when not used, and the requirement on multiple use functions is met; the supporting device is simple in structure and convenient to operate and use; moreover, drill pipe threading quality during drill pipe threading is also improved, labor intensity is lowered, and unsafe factors in threading production are decreased.

Description

[0001] technical field [0002] The invention relates to a supporting device suitable for passing wires of coal mine drill rods, belonging to the field of coal mine drilling equipment. Background technique [0003] During the drilling construction process, the coal mine drill pipe wears seriously after being used for a certain period of time, and the drill pipe needs to be threaded again before it can be used. In the prior art, the drill pipe is usually manually lifted to operate the equipment for threading. Using the existing This operation mode not only easily makes the quality of the drill pipe unqualified, but also makes the labor intensity of the operator high, and there are also unsafe factors. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a coal mine drill pipe over-wire support device with simple structure, convenient operation and multi-function. [0005] In order to solve the above-mentioned technic...
