Dust fall grading drilling device convenient for position adjustment in mine tunnel

Abstract

The invention discloses a dust falling and grading drilling device facilitating position adjustment in a mine tunnel. The dust falling and grading drilling device comprises a multi-angle bending device capable of being lifted in a labor-saving mode, a splicing type hole washing and dust falling device, a multi-stage extending drilling device and a drilling equipment shell. The invention belongs to the field of mine tunnel drilling equipment, and particularly relates to a dust fall grading drilling device convenient for position adjustment in a mine tunnel. According to the invention, the air impinging stream is combined with the versatility of equipment, the space range of dust splashing is limited in advance, and the settling velocity of dust in a narrow mine tunnel is accelerated; in order to facilitate movement of the moving device in the mine tunnel with multiple gaps and prevent the moving device from being clamped in the gaps, the crawling equipment can quickly move on the inner wall of the mine tunnel by combining an asymmetric principle with a conical structure; in order to carry out deep drilling in a narrow space, the traditional operation mode of linear drilling of a single drill bit is changed, and two groups of nested drill bits are used for drilling, so that a multi-stage drilling function in a mine tunnel is realized.

Description

technical field [0001] The invention belongs to the technical field of mine tunnel drilling equipment, in particular to a dust-suppressing graded drilling device that is convenient for position adjustment in a mine tunnel. Background technique [0002] Underground mining refers to the process of extracting ore from the ore blocks of underground deposits, which is realized through four steps of mine development, mining of ore blocks, cutting and mining. The underground mining system mainly includes production management, rock drilling, blasting, ore extraction, ore sliding system, underground crushing, skip lifting and hoisting shaft system. [0003] During the mining of underground mineral deposits, due to the narrow space of the underground mine, when the construction personnel need to drill holes on the side wall of the mine, the drilling equipment will be too long to carry out the drilling work in the narrow space, resulting in the The depth of the drilled hole is relati...

Problems solved by technology

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a dust-suppressing graded drilling device that is convenient for position adjustment in the mine tunnel. Starting from the spatial position of the contact position between the equipment and the inner wall of the mine tunnel, the present invention combines the principles of presetness, impact flow and versatility into the present invention. By changing the shape of the traditional mechanical crawling arm, the dust splash is limited in advance. In the moving area of ​​the mine, the impact flow is used to enhance the efficiency of the water mist to settle the dust, which effectively improves the dust content in the air in the mine tunnel; in order to solve the problem that the crawling device on the equipment can increase the resistance on the inner wall of the mine tunnel (to facilitate the crawling of the equipment), It can also reduce the technical problem of resistance (avoid the crawling device from being stuck in the rock gap), creatively apply the principle of asymmetry in the present invention, through three sets of conical support devices evenly distributed on the conical crawling structure, it can be 360 The degree of support for the crawling equipment that is about to slide, and due to the shape characteristics of the cone, can effectively avoid the technical problem that the crawling device is stuck in the gap between the ores; in order to be able to carry out deep drilling in narrow mines with small width The principle of nesting is applied in this invention. Through the nesting effect of two sets of drill bits, the preset function of deep drilling in a narrow space is realized, which effectively solves the low working efficiency of the existing mine tunnel drilling equipment on the market. , and its own complex structure and inconvenient maintenance
