A mining shaft drilling device that avoids collapse

Abstract

The invention relates to the field of mining equipment, in particular to mining vertical shaft drilling equipment avoiding collapse. A machine body and a boss fixedly arranged on the right side end wall of the machine body are included. A drill bit capable of moving up and down is arranged in the bottom wall of the boss. A sliding cavity with a rightward opening is formed in the right side end wall of the machine body. An elevating device for elevating the drill bit is arranged in the sliding cavity. A switching cavity is formed in the machine body and internally rotationally provided with a spline sleeve. According to the provided mining vertical shaft drilling equipment avoiding collapse, mining vertical shaft drilling can be achieved, meanwhile, the equipment can strengthen the inner wall of a vertical shaft, and vertical shaft inner wall collapsing is effectively prevented. The equipment is simple in operation and structure, independent moving can be achieved, usage is very convenient, the equipment is safe, stability is good, and production, popularization and usage are convenient.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to mining shaft drilling equipment for avoiding collapse. Background technique [0002] When people are drilling into mines, there are often serious accidents caused by soil collapse. Traditional drilling equipment cannot reinforce the inner wall of the shaft during the shaft drilling process. At the same time, the traditional equipment is inconvenient to move and the degree of automation is not high, resulting in low work efficiency during drilling. Low, can not provide assistance for the operator conveniently, so it is necessary to set up a kind of mining shaft drilling equipment that avoids collapse to improve the above problems. Contents of the invention [0003] The object of the present invention is to provide a mining shaft drilling equipment which can avoid collapse, which can overcome the above-mentioned defects of the prior art, thereby improving the practicability of the...
