Abstract

The invention belongs to anchor rod support equipment, and particularly relates to an anchor drilling jig provided with a rod-protection mechanical hand and used for a coal mine. A sliding frame assembly is mounted on a frame assembly. A long feeding oil cylinder is mounted at the bottom of the frame assembly. A cylinder barrel lug base of the long feeding oil cylinder is connected with a long feeding oil cylinder fixing lug base of the frame assembly. A cylinder rod lug base of the long feeding oil cylinder is connected with a top plate of the sliding frame assembly. A guide connecting platewhich can slide relatively is mounted on the sliding frame assembly and is fixedly connected with a drilling box. A top rod back-hooking device which can turn a mechanical paw is fixed to one side ofthe drilling box. A mechanical hand protection arm and the mechanical paw are connected to the frame assembly. One end of a chain transmission device is connected with the guide connecting plate, andthe other end of the chain transmission device is connected with the sliding frame assembly. The chain transmission device is wound on a short feeding oil cylinder through a sliding wheel assembly, and the guide connecting plate is improved by multiple times through a sliding wheel device composed of a short feeding oil cylinder stretching chain drive device and the guide connecting plate.

Description

technical field

[0001] The invention belongs to rock bolt support equipment, in particular to a rock bolt drill for coal mines with a manipulator of a protective rod. Background technique

[0002] The current support method in the roadway excavation process is mainly bolt support. During the anchoring and protection process of the rock bolter, sometimes the phenomenon of rod throwing or even broken rods may occur. Therefore, when the rock bolter is anchoring and protecting, workers often need to protect the drill pipe with their hands and go up to the top position, which is very dangerous and greatly affects Drilling speed. How to realize the automatic protection rod through the protection rod device that comes with the rock bolt rig is an urgent problem to be solved to solve the bolt throwing of the anchor drill and ensure the safety of workers' anchor protection work. At the same time, in the current roadway anchor protection operation, there is a serious problem of unba...
