Problems solved by technology
[0002] Coal mines need continuous excavation during the mining process, and cover is required during the excavation process to avoid sudden landslide accidents during the excavation process. The cover method in the prior art is mainly through support, but the construction of support is a waste of time , unable to keep up with the excavation speed of mining equipment, resulting in the need for mining equipment to cooperate with the installation of supports, reducing mining efficiency

The invention discloses a driving covering device for mine exploitation. The device comprises a baseplate, a top plate and a force bearing plate as well as more than four first sleeve parts which are symmetrically disposed on the top of the baseplate, wherein second sleeve parts matched with the first sleeve parts are disposed on the bottom of the top plate; support rods are matched between the first sleeve parts and the second sleeve parts; more than two guide rods are disposed on the top of the top plate; the guide rods are movably inserted in the force bearing plate; a damping plate spring is firmly disposed on the bottom of the force bearing plate; the lower end face of the damping plate spring is pressed against the top plate; more than four rollers are disposed symmetrically on the bottom of the baseplate; and guide rails matched with the rollers are disposed on the bottom of the baseplate. The device can be moved by the rollers, so exploitation equipment can be covered easily and collapse accidents can be avoided; after moving of the device, supports can be established at positions within the stroke, so guarantee effects are achieved; and the device can greatly increase the mine exploitation efficiency.
Description
technical field [0001] The invention relates to a driving protection device for coal mine exploitation. Background technique [0002] Coal mines need continuous excavation during the mining process, and cover is required during the excavation process to avoid sudden landslide accidents during the excavation process. The cover method in the prior art is mainly through support, but the construction of support is a waste of time , unable to keep up with the excavation speed of mining equipment, resulting in the need for mining equipment to cooperate with the installation of supports, reducing mining efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tunneling protection device for coal mine development. The device can be moved by rollers to facilitate the protection of mining equipment and avoid landslide accidents. Then build supports to play a protective role. This device can greatly improve the mining...
