Description

Tunnel roof protective equipment Technical Field The application relates to the technical field of mining equipment, in particular to roadway roof protective equipment. Background The tunnel is a necessary production and life channel in an underground coal mine, and in the engineering design of the tunnel, the condition that the tunnels are intersected in a close-distance and three-dimensional way is unavoidable in order to reduce the tunneling engineering quantity and meet the requirements of safe and efficient production of the mine. In the construction process of short-distance stereo intersection of the roadways, when a new tunneling roadway is on the top and an existing roadway is under, the relative position and distance between the new tunneling roadway and the existing roadway in space are accurately measured, and then the existing roadway support is reinforced as soon as possible at the crossing section of the roadway, so that the construction safety and the roadway stability are ensured. At present, in the aspect of tunnel intersection construction protection, a traditional reinforcing and supporting mode of manually erecting an interchange protection frame is still adopted, in the process of manually erecting the interchange protection frame, the operation steps are complex, the working procedures are complex, the labor intensity is high, time and labor are wasted, the cost is extremely high, and in addition, great potential safety hazards exist in the construction process, so that the safety of constructors cannot be effectively ensured.
