Hole sealing pipe tripping-in device

Abstract

The invention provides a hole sealing pipe tripping-in device. The hole sealing pipe tripping-in device comprises a support, an operating system, a workbench, a straightening device and a clamping device. The hole sealing pipe tripping-in device can be used for drilling holes at different angles by adjusting the height of the support, the operating device achieves the clamping-feeding and loosening-retracting functions of the clamping device through mechanical transmission, the straightening device is fixed to the workbench and used for straightening a disc-shaped PVC hole sealing pipe, the PVC hole sealing pipe can be conveniently fed into the drilled holes, and the clamping device moves along a guide rail to achieve tripping-in of the hole sealing pipe. The hole sealing pipe tripping-indevice has the advantages that the original manual pipe feeding operation of workers is changed, the hole sealing construction efficiency can be improved, the downhole operation safety is improved, and the hole sealing pipe tripping-in device has important significance in coal mine safety production.

Description

technical field [0001] The invention relates to the technical field of underground hole sealing construction in coal mines, in particular to a device for lowering a sealing pipe. Background technique [0002] In order to ensure safe production in coal mines, coal seam gas needs to be extracted before excavation, so a certain number of boreholes must be constructed in the coal seam, but due to changes in coal quality, geological factors, stress and other factors, it is easy to cause boreholes Collapse and blockage will affect the extraction effect. In order to improve the effect of gas drainage, the mine uses a PVC sealing pipe to be lowered into the borehole, and then it is sealed and fixed, and the gas drainage is carried out through the sealing pipe. [0003] At present, in the process of sealing holes in coal mines, manual operation is generally used to lower the pipes. For drilling holes at various angles, the construction operation is time-consuming and laborious, and ...

AI Technical Summary

Problems solved by technology

[0003] At present, in the process of sealing holes in coal mines, manual lowering is generally used. For drilling holes at various angles, the construction operation is time-consuming and laborious, and the efficiency is not high.

The PVC sealing pipe purchased from the coal mine is disc-shaped when used, and it is more difficult to install the pipe manually. Moreover, due to the bending, the sealing pipe is easy to get stuck in the drill hole, and the labor intensity of the workers is high.

For drilling with a long sealing length, there is a risk of the sealing tube falling off and hurting people when sealing the hole
