Abstract

The invention discloses an automatic drill rod loading and unloading device applicable to a coal mine underground drilling machine. The device comprises a manipulator unit, a drill rod bracket, a drill rod storage rack and a drill rod hoisting unit; the manipulator unit comprises a grab and a regulating unit, the grab is mounted at the end of the regulating unit, the regulating unit comprises a plurality of telescopic sleeves arranged horizontally and vertically and connected mutually; the drill pipe bracket comprises a drill rod storage box and a brace, and a plurality of tray supports are hinged to one side of the drill rod storage box; the drill pipe storage rack comprises two U-shaped clamp plates parallel to each other and provided with opening in opposite horizontally, and a draw baris detachablely connected between the two U-shaped clamp plates; the drill rod hoisting unit comprises a guide rail capable of driving the drill pipe storage rack to move between the position above the drill pipe bracket and the drill pipe storage position. The automatic drill rod loading and unloading device realizes continuous loading and unloading of drill pipes, reduces labor intensity of operators, decreases danger coefficient of underground work, and increases automation level in loading and unloading of the drill pipes for the coal mine underground tunnel drilling machine.

Description

technical field [0001] The invention belongs to the technical field of underground drilling in coal mines, and in particular relates to an automatic rod loading and unloading device suitable for underground drilling rigs in coal mines. Background technique [0002] Coal seam gas drainage drilling construction is developing in the direction of large diameter and long holes. The diameter of the drill pipe used for construction has reached φ127mm, the weight of a single drill pipe exceeds 50kg, and the cumulative length of the drill pipe used for construction is nearly 1,000 meters. Adding and unloading drill pipes is a key process in gas drainage drilling, which has a significant impact on drilling efficiency. At present, manual loading and unloading of drill pipes is mostly used in the process of gas drainage drilling. As the weight of a single drill pipe continues to increase, the disadvantages of manual loading and unloading of drill pipes are gradually emerging. The time ...
