Description

Technical Field

[0001] The utility model relates to the technical field of soil or rock drilling, in particular to a net hanging device for a drilling and anchoring integrated machine. Background Art

[0002] A bolter and digger is an integrated machine that combines a tunnel boring machine and an anchor bolter, enabling the two machines to operate in parallel. A Chinese utility model patent, authorized with publication number "CN217055202U," discloses an automatic mesh-laying device for this machine, belonging to the field of integrated tunnel boring machines. The device comprises a tunnel boring machine with a lifting mechanism affixed to its top. Two anchor bolters are affixed to the top of the lifting mechanism in a front-to-back symmetrical configuration. A mounting frame is affixed to the top of the lifting mechanism. The inner wall of the mounting frame is symmetrically connected to two support arms, each with a bracket affixed to its top. The lifting mechanism drives the mounting frame upward, and two rollers press the steel mesh against the top plate. The two support arms expand to the sides, and a slider slides along the support arms. As the sleeve slides downward along the slide rod, it compresses the spring, causing the two rollers to straighten the steel mesh, preventing it from loosening during movement. The anchor bolters then secure the steel mesh on both sides, improving mesh installation efficiency.

[0003] The above technical solution drives the mounting frame to extend upward through the lifting mechanism, and the two rollers squeeze the steel mesh on the top plate, while the two support arms open to both sides, and the slider slides along the support arms. While the sliding sleeve slides downward along the slide rod, it squeezes the spring, so that the two rollers straighten the steel mesh to avoid the steel mesh from becoming loose during the movement of the mining and anchoring machine. However, the above technical solution still has certain defects. For example, the above equipment squeezes the steel mesh on the top plate through two rollers to straighten the wire mesh. However, when the rollers need to be maintained and repaired after long-term use, the staff need to use special tools to disassemble the entire bracket, and then disassemble the rollers. This increases the workload of the staff and reduces the maintenance and repair efficiency of the rollers. Utility Model Content
