Abstract

The invention discloses a repairing machine for a broken loading roadway. The machine comprises a vehicle body part and an execution mechanism, wherein the vehicle body part comprises a work table, a driving device, a walking device, an oil tank and supporting legs, the driving device is in hydraulic transmission with the walking device, is a hydraulic driving device placed at the rear part of the work table and comprises an anti-explosion motor and an oil pump, the anti-explosion motor drives the oil pump by a coupler, the input opening of the oil pump is communicated with the oil tank by an oil-way, and the output opening of the oil pump is communicated with two oil-way control valves by the oil-way; liquid is supplied to the walking device and each oil cylinder by the two oil-way control valves.

Description

technical field [0001] The invention relates to a crushing and loading roadway maintenance machine for coal mines. Background technique [0002] The current vertical and horizontal rotation of the current crushing and loading roadway maintenance machine for coal mines uses a torque transmission box. The rack and gear in the transmission box are driven by a hydraulic source and an oil cylinder to achieve rotation. During rotation, there is a gap between the gear and the rack. , a deflection phenomenon occurs during rotation. When replacing the breaking hammer, because the breaking hammer is relatively heavy, it will bring great inconvenience to the construction personnel when replacing it. The oil pipes supplied by the multi-way valve to the bucket, breaking hammer, large and small arms, and the rotary transmission box are hung on both sides and are easily damaged. When the boom rotates horizontally left and right, the whole machine is prone to rollover due to the large rot...
