High-outburst coal mine coal roadway drilling-loading-bolting integrated machine

Abstract

The invention relates to a high-outburst coal mine coal roadway drilling-loading-bolting integrated machine comprising a hydraulic lane top temporary support, an onboard outburst-proof drilling machine, an electric control system, a loading part, an onboard jumbolter, a running gear, an operating floor, a main stand, a rear supporting assembly, a scraper conveyor, a discharge hole reversing device, an oil tank pump station and a motor. In the technical scheme of the invention, the high-outburst coal mine coal roadway drilling-loading-bolting integrated machine can organically integrate various coal roadway jobs, such as gas drainage deep well drilling, coal roadway top bolting, coal roadway side bolting, top plate hydraulic support temporary support, loading and the like and integrates the functions of loading, walking, support, gas drilling and drainage, onboard rock bolt and the like.

Description

technical field [0001] The invention relates to a drilling, anchoring and supporting transportation technology in high gas outburst coal mines or low gas coal mines, in particular to a multifunctional integrated machine for drilling, anchoring and supporting transportation in coal lanes of high outburst mines. Background technique [0002] At the present stage, there is no unit capable of drilling gas holes and carrying out anchor protection operations at the same time in China, and most of them rely on manual hand-held bolter rigs. Drilling and draining gas deep holes also mostly rely on a single drilling mechanism, and the shipping equipment is a scraper conveyor, and the discharge port is fixed. On the other hand, the existing deep hole drilling mainly relies on the drilling equipment equipped with airborne drilling rigs. The equipment has a single function. When it is narrow and needs to help and push the bolt at the same time, it is necessary to evacuate the equipment ...

AI Technical Summary

Problems solved by technology

On the other hand, the existing deep hole drilling mainly relies on the drilling equipment equipped with airborne drilling rigs. The equipment has a single function. When it is narrow and it is necessary to help and jack the bolt at the same time, it is necessary to evacuate the equipment from the working surface

The main problem of this kind of operation method is that the fully mechanized excavator drives in and out very frequently, the start-up rate is not high, the single-body bolter relies on frequent manual movement, and the temporary support is not in place ahead of time, which cannot effectively protect the safety of anchor workers , so that the auxiliary operation time is longer, more people are occupied, the excavation efficiency is low, the labor intensity of the workers is high, and the level of single entry is low, etc.

At the same time, the discharge port of the loading system of the existing equipment is parallel to the main shaft of the drilling, which is not conducive to the transfer of coal or gangue between mine cars, belt conveyors, scraper machines, etc.

Existing rock bolt rigs are mostly used manually, with high labor intensity, and need to be equipped with independent pumping stations, which are complicated to use and work in bad ways
