Deep mine drilling traction device

Abstract

The invention relates to the field of mineral resource mining machinery, and particularly relates to a deep mine drilling traction device. The deep mine drilling traction device comprises a traction head, a crawling mechanism and an explosion-proof motor; the crawling mechanism comprises steel bar hoops which are coaxially arranged, and steel bar sticks which are jointly welded to the outer edges of all the steel bar hoops in the axial direction of all the steel bar hoops; the steel bar hoops and the steel bar sticks form a cylindrical steel bar frame body; worm wheels are rotationally mounted on the steel bar hoops located between the adjacent steel bar sticks; a worm is arranged in the steel bar frame body in a penetrating mode, and all the worm wheels are matched with the worm; an output shaft is fixedly arranged in the worm; and one end of the output shaft is coaxially and fixedly connected with the other end of a rotating shaft of the traction head, and the other end of the output shaft is coaxially and fixedly connected with the output end of the explosion-proof motor. The deep mine drilling traction device can crawl in two directions, after fracturing operation of a section of drilled hole is completed, the deep mine drilling traction device can crawl backwards to the next section of drilled hole to continue fracturing operation, and the deep mine drilling traction device can be applied to staged fracturing operation of deep mine drilling.

Description

technical field [0001] The invention relates to the field of mineral resource mining machinery, in particular to a deep mine drilling traction device. Background technique [0002] In recent years, with the continuous increase of mining intensity, the mining depth of my country's coal mine resources has increased at a rate of 8 meters to 12 meters per year. A large number of coal mines have rapidly entered the deep mining stage, and deep mine mining is more difficult. [0003] In order to ensure the safety of the staff, before mining the coal mine, it is necessary to extract the coalbed methane in the gap of the coal reservoir. When coalbed methane is exploited, it is necessary to use a fracturing device to form several cracks in the coal seam in the operation area. This process is called fracturing. Currently, prior to fracturing operations, it is necessary to drill a channel hundreds of meters deep and slowly feed the fracturing device wound on the winch into the borehole...
