Description

Technical Field

[0001] The utility model belongs to the technical field of explosion isolation, in particular to a movable automatic explosion isolation device. Background Art

[0002] Gas explosions in coal mines are extremely dangerous. To isolate the explosions, currently used explosion-proof devices are mostly triggered by shock waves, using high-pressure gas to spray out fire-extinguishing powder to achieve explosion-proof effects.

[0003] Some tunnels are relatively low, and the explosion-proof device needs to be removed when passing super-high vehicles, and then reinstalled after the vehicles pass. On the one hand, repeated installation is labor-intensive, and on the other hand, it increases the cost of use. In order to solve the above problems, a movable automatic explosion-proof device is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a movable automatic explosion-proof device to solve the problem that some tunnels are low and the explosion-proof device needs to be removed when an over-high vehicle passes through, and then reinstalled after the vehicle passes. On the one hand, repeated installation is labor-intensive and on the other hand, the cost of use is increased.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] A plurality of lifting rings are fixedly installed on the upper surface of the inner wall of the first slide rail, and fixed pulleys are fixedly installed on the lower surfaces of both ends of the first slide rail. The traction rope passes through the lifting rings and the fixed pulleys in sequence. By setting the fixed pulleys and lifting rings, it is possible to effectively avoid the traction rope from being entangled with the first movable pulley when pulling the explosion-proof device, thereby further improving practicality.

This reduces the need for removal and installation of the explosion-proof device, reduces employee labor intensity, and extends the service life of the automatic explosion-proof device, thus offering high practicality. By providing a fixed pulley, a lifting ring, and an anti-entanglement lead bob, this utility model effectively prevents the traction rope from becoming entangled with the first movable pulley when pulling the explosion-proof device, further enhancing its practicality. Of course, any product implementing this utility model does not necessarily need to simultaneously achieve all of the advantages described above. BRIEF DESCRIPTION OF THE DRAWINGS
