[0021] The utility model will be explained in detail below in combination with the drawings and specific embodiment.

[0022] At present, when disaster occurs, the underground air door slide hole is difficult to close or close tightly, and cannot effectively prevent the spread of disaster.

[0023] The utility model discloses a roadway wind wall slide hole blocking device, including blocking plate 70 and hook assembly;Blocking plate 70 with the hole body section shape on the belt 80 is same, and the size is consistent, and the top end of blocking plate 70 is rotatably connected to the top end of hole body, and the hole body is the hole body for the belt 80 to pass through on the wind wall;Blocking plate 70 is provided with the hanging ring;Hook assembly is fixed on the wind wall wall body 90 above the hole body;Among them, hook assembly is used to cooperate with the hanging ring, to pull up the bottom of blocking plate 70.The hole body of above-mentioned refers to the hole body of wind wall slide hole.

[0024] The utility model discloses through installing the blocking plate on the hole body on the belt, and combining the hook assembly on the wind wall wall body, thereby can realize the pull -up or put down of blocking plate, when the gas explosion occurs in the roadway, put down the blocking plate, can prevent the gas diffusion outward.

[0025] For example, Figure 1 And Figure 2As shown, the hook assembly comprises an outer sleeve 20 fixed on the wind wall body 90, and an inner sleeve 30 arranged in the outer sleeve 20; the inner sleeve 30 can move axially relative to the outer sleeve 20. Moreover, the bottom of the inner sleeve 30 is connected with a transverse hanging rod 50 through a vertical connecting vertical rod 60, and the hanging rod 50 has the same direction as the belt. When normal production, the hanging ring on the blocking plate 70 is hung on the hanging rod 50, and does not affect the operation of the lower belt 80 and the transportation of the materials thereon. Once a gas explosion occurs, the inner sleeve 30 moves towards the wind wall body 90, so that the hanging rod 50 is separated from the hanging ring, and the blocking plate 70 rotates downward with its top end as the axis under the action of gravity until vertical static, at this time, the blocking plate 70 just blocks the hole above the belt 80.

[0026] In the utility model, the bottom of the outer sleeve 20 is provided with a strip-shaped through hole for the connecting vertical rod 60 to pass through. The length direction of the strip-shaped through hole is arranged along the circumference of the outer sleeve, so that the inner sleeve 30 can drive the connecting vertical rod 60 and the hanging rod 50 to move in the strip-shaped through hole in turn, thereby realizing the fixing and separation of the hanging rod 50 and the hanging ring.

[0027] In one embodiment, the end of the inner sleeve 30 located outside the outer sleeve 20 is provided with a pressure bearing plate 40, and the pressure bearing surface of the pressure bearing plate 40 is parallel to the wind wall body 90. The shape of the pressure bearing plate 40 is not limited, and can be designed according to actual needs, such as circular, oval, quadrilateral and the like.

[0028] As shown in the figure, it is a state diagram when normal production. When a gas explosion occurs, the airflow with strong pressure will press the pressure bearing plate 40, and the pressure bearing plate 40 will drive the inner sleeve 30 to move towards the wind wall body 90, as shown in the figure, the hanging rod 50 and the hanging ring are separated, and the blocking plate 70 falls to block the space above the belt of the chute hole, preventing gas from spouting from the hole. Figure 3 Figure 4 As shown, the hook assembly comprises an outer sleeve 20 fixed on the wind wall body 90, and an inner sleeve 30 arranged in the outer sleeve 20; the inner sleeve 30 can move axially relative to the outer sleeve 20. Moreover, the bottom of the inner sleeve 30 is connected with a transverse hanging rod 50 through a vertical connecting vertical rod 60, and the hanging rod 50 has the same direction as the belt. When normal production, the hanging ring on the blocking plate 70 is hung on the hanging rod 50, and does not affect the operation of the lower belt 80 and the transportation of the materials thereon. Once a gas explosion occurs, the inner sleeve 30 moves towards the wind wall body 90, so that the hanging rod 50 is separated from the hanging ring, and the blocking plate 70 rotates downward with its top end as the axis under the action of gravity until vertical static, at this time, the blocking plate 70 just blocks the hole above the belt 80.

[0029] The end of the outer sleeve 20 is fixedly installed on the wind wall body 90 through the connecting plate 10, and the fixing mode of the outer sleeve 20 can be simplified through the connecting plate 10.​
