Embodiment Construction

[0014] Such as figure 1 , figure 2 As shown, the track-type underground roadway waterproof sealing door includes an underframe 1, a door panel 2, a door frame 3, an underframe rail 4 and an assembly 5, and the material used is metal. The door panel 2 is rotatably installed on the door frame 3, the door frame 3 is combined with the underframe 1, and the assembly 5 is installed on the underframe 1, and can move laterally on the underframe rail.

[0015] Such as image 3 , Figure 4 As shown, the door panel 2 is rectangular, surrounded by sealing rubber strip 6, and the sealing rubber strip 6 is between the joint surface of the door panel 2 and the door frame 3; at the upper and lower positions on one side of the door panel 2, there are wedges connected and fixed by iron chains 7. The iron 8 has a wedge groove 9 matching the wedge iron 8 on the door frame 3. When the sealed door is closed, the wedge iron 8 is inserted into the wedge groove 9, and a positive pressure chamber i...

Abstract

The invention relates to a rail-mounted waterproof sealing door for downhole roadways. By the aid of the rail-mounted waterproof sealing door, water can be separated from people at first time if water inrush accidents occur in the downhole roadways, so that the maximum escape time can be provided for people. The rail-mounted waterproof sealing door comprises a door panel, a door frame, an underframe, underframe steel rails and a combination and is made of metal. The door panel is rotatably mounted on the door frame, the door frame is integrally combined with the underframe, and the combination is mounted on the underframe and can transversely move on the underframe steel rails. The door panel is rectangular, sealing adhesive tapes are inlaid in the periphery of the door panel, the underframe is rectangular, and a clamp pin is arranged in the middle of the underframe and is used for clamping combination light rails, so that the combination light rails can keep being accurately butted to roadway light rails. The rail-mounted waterproof sealing door has the advantages that the sealing door can be closed and locked once the water inrush accidents occur, so that the inrush water can be blocked; the rail-mounted waterproof sealing door is simple in structure, low in cost and suitable for downhole roadways which are prone to water inrush accidents, and can be operated conveniently and quickly, a good sealing effect can be realized, and a use technology of the rail-mounted waterproof sealing door is convenient to popularize.

Description

technical field [0001] The invention belongs to the technical field of mining, in particular to a rail-type underground roadway waterproof sealing door. Background technique [0002] Coal mine water seepage accident is one of the key prevention contents of coal mine safety production in my country. Coal mine water seepage refers to accidents caused by digging through the wall of the tunnel to connect to groundwater or accumulated water when mining coal in the tunnel. According to the official data of the State Administration of Work Safety and the Coal Supervision Bureau, according to incomplete statistics, from 2000 to 2011, the large coal mine flooding accidents in my country gradually increased in a wave-like manner. The reason is that when the management was tightened, the frequency of accidents slowed down slightly, but after the crackdown, the accidents continued to rise in a straight line. Although in recent years, as the state has continuously strengthened the safet...
