Tunnel repairing equipment for coal mine

Abstract

The invention discloses tunnel repairing equipment for a coal mine. The tunnel repairing equipment comprises a tank body, a driving device is arranged on the right side of an inner cavity of the tankbody, a driven mechanism is arranged on the left side of the driving device, limiting mechanisms are arranged on the two sides of the upper side and the lower side of the driven mechanism, a drillingmechanism is arranged on the left side of the tank body, a residue discharging mechanism is arranged on the right side of the bottom of the tank body, the driving device comprises a hydraulic rod, andthe right end of the hydraulic rod is fixedly connected to the inner cavity of the tank body. According to the tunnel repairing equipment for the coal mine, through arrangement of the tank body, thedriving mechanism, the driven mechanism, the limiting mechanisms, the drilling mechanism and the residue discharging mechanism, stability of drilling can be increased, and meanwhile, the problems thata drill bit of a traditional repairing equipment has a poor damping property and can bring heavy damage to the part of a drilling rod during meeting hard rocks, and the service life of the drilling rod is shortened are solved; and the tunnel repairing equipment for the coal mine has the advantage of good damping effect, and deserves popularization.

Description

technical field [0001] The invention relates to the technical field of roadway restoration, in particular to roadway restoration equipment for coal mines. Background technique [0002] With the continuous progress of the modern production technology of coal mines, the main production equipment of fully mechanized mining and fully mechanized excavation face has basically been mechanized, and gradually develops towards automation. Ditch, roadway expansion, and accessories material hoisting and transportation, etc., the repair equipment used is driven by full hydraulic power, and the universal mechanical arm cooperates with the interchangeable working mechanism to realize excavation, side digging, rock breaking, side expansion, and erection. The roadway repair of sheds and other mechanized operations, the hoisting and transportation of accessories and materials can be realized through the lifting hook installed on the mechanical arm, and the roadway leveling can be carried out ...
