Abstract

The invention discloses a breaking loading roadway repairing machine. A vehicle body part comprises a worktable, a driving device, a running device, an oil tank and a supporting leg, wherein the driving device and the running device adopt a hydraulic transmission mode, the driving device is a hydraulic driving device, is arranged at the rear portion of the worktable and comprises an explosion-proof diesel engine and an oil pump, the explosion-proof diesel engine transmits the oil pump through a coupler, an input port of the oil pump and the oil tank are communicated through an oil path, and an output port of the oil pump and two sets of oil path control valves are communicated through oil paths. Liquid is supplied to the running device and each oil cylinder through the two sets of oil path control valves, the H-shaped supporting leg is arranged at the rear portion of a support of the vehicle body, and the supporting leg is matched with a supporting leg guide rail in a sliding mode.

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...
