Description

Technical Field

[0001] The utility model relates to a lifting and lowering pneumatic pick top picking device, belonging to the technical field of coal mine mechanical equipment. Background Art

[0002] The surrounding rock structure of coal mine tunnels is complex, mainly composed of coal seams, roofs, floors and lithological layers on both sides. Tunnel excavation is an important part of coal mining. In the actual construction process, some tunnel rock masses need to be broken manually using pneumatic picks. The crushing problem is often a key factor hindering mining work.

[0003] At present, the rock crushing construction in underground coal mine tunnels mainly uses pneumatic picks for rock breaking. When breaking the tunnel bottom plate and the two sides of the rock, it is easier to complete the work manually with pneumatic picks. However, when breaking the top plate rock of the tunnel, it is necessary to lift the pneumatic picks manually. Manual lifts can only be made of small J10 pneumatic picks, which is labor-intensive and inefficient. The falling of broken rock caused by the working vibration of the pneumatic picks can easily injure the operators, leading to personal safety accidents and greater safety risks.

[0004] Therefore, we proposed a liftable pneumatic pick top lifting device to effectively solve the above problems, ensure the safe distance between the operators and the broken rock mass, reduce the labor intensity of the operators, increase the continuous operation time, and improve the construction efficiency.
