Abstract

The invention provides a drill bushing assembly and a novel drill box for automatic anchor protection operation, and belongs to the technical field of roadway supporting, and the drill box comprises a drill box body, a drill box motor, a motor transmission shaft, a damping piece, a damping type anchor rod, a drill bushing and an abutting column. Wherein the drilling box motor and the liquid distribution plate are mounted on the drilling box body, and the drilling sleeve is connected with the motor transmission shaft to transmit torque; the tray clamping claws are symmetrically assembled on the drilling box body in a detachable mode and can limit the anchor rod tray. The drill bushing is provided with the damping piece disengaging hole in a double-inclined-face mode, the damping piece can be disengaged through the damping piece disengaging hole in the anchoring process, the drill bushing is in a multi-face limiting mode, and therefore the drill rod is more convenient to disassemble. According to the drilling box, the reliability is improved, the service life of the drilling box is prolonged, the working safety and efficiency are improved while the labor intensity of automatic anchor protection operation is reduced, and the automation and standardization progress of the anchor protection operation is promoted.

Description

technical field

[0001] The invention belongs to the technical field of roadway support, and specifically discloses a drill sleeve assembly and a novel drill box for automatic anchoring operation. Background technique

[0002] The underground mining method is the main mining method of coal resources in China. The support working face is a densely distributed workplace for mine operators, and the support work is carried out immediately after the tunnel is excavated, and the operating environment is also relatively harsh. The traditional supporting process mainly relies on manual drilling and anchoring. There are defects such as single function of anchoring equipment, poor matching coordination, low operation efficiency, many people, and poor safety. Therefore, it is easy to cause serious mining imbalance.

[0003] At present, the intelligent anchoring machine has begun to be developed and gradually replaced the traditional bolting machine. It is found through experiments that ...
