Description

Technical Field

[0001] The utility model relates to the field of mining area barriers, in particular to a mining area reciprocating safety door device. Background Art

[0002] In the northern grassland mining area, the mining area is surrounded by pastures of herders. The cattle and sheep raised by herders often enter the industrial site of the mining area to avoid wind and sand. Because there are many equipment and pipelines in the industrial site, which will cause damage to cattle and sheep, in order to protect the private property of herders, the company installed an automatic gate at the entrance. However, the upside-down gate purchased on the market cannot meet the erosion of severe weather. When it is affected by strong winds on the grassland or collisions between cattle and sheep, the existing gate railings are easily deformed and damaged, and cannot operate normally, affecting the normal passage of the mining area. Utility Model Content

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0020] like Figure 1 As shown, a reciprocating safety gate device for a mining area comprises a storage box 2 and a column 13 arranged on both sides of a mining area entrance and exit 1. A gate 3 which can be pushed and pulled and closed with the column 13 is arranged in the storage box 2. The gate 3 is automatically pushed and pulled by a gear rack mechanism arranged in the storage box 2. The gear rack mechanism has better resistance to wind and sand erosion and prolongs its service life. A limit assembly is arranged in the storage box 2 to realize smooth movement of the gate 3.

[0021] like Figure 2 As shown, the rack and pinion mechanism includes a rack 9 arranged at the bottom of the gate 3, and a plurality of supporting gears 7 meshing with the rack 9 are arranged at the lower part. The supporting gears 7 mainly play the role of supporting the gravity of the gate 3, and the supporting gears 7 are rotatably supported by the supporting shaft 8 and the inner wall of the storage box 2.

[0022] A meshing driving tooth 10 is also provided at the lower portion of the rack 9 , and the driving tooth 10 is drivingly connected to a driving motor 11 installed in the storage box 2 , and the driving motor 11 is electrically connected to a gate controller 14 provided at one side of the mine entrance 1 .

[0023] The driving motor 11 is fixedly connected via a mounting bracket 12 installed in the storage box 2 .

[0024] The limiting assembly includes multiple groups of roller assemblies arranged at the upper and lower ends of the gate 3, each roller assembly includes a limiting roller 4 arranged on both sides of the frame of the gate 3, and the limiting roller 4 is fixed by a support frame 5 installed in the storage box 2. The limiting roller 4 prevents the gate 3 from being offset and deformed, and provides higher stability for the heavier gate 3.

[0025] A plurality of horizontal rollers 6 that fit the gate 3 are also provided on the upper portion of the frame. The horizontal rollers 6 are installed inside the storage box 2. The horizontal rollers 6 can prevent the gate 3 from deflecting when it is extended and closed.

[0026] The width of the rack 9 is smaller than the width of the frame of the gate 3 , so that the support of the gate 3 by the limiting assembly is not affected.

[0027] The side of the column 13 is provided with a groove for closing with the end of the gate 3. The groove limits the end of the gate 3 to prevent deformation due to strong winds or collisions with cattle and sheep, so that the force on the gate 3 is more uniform and reasonable.

[0028] The outer side of the gate 3 is provided with a metal frame, the gate 3 is provided with a metal square steel frame, and a metal mesh is arranged inside the metal frame, so that the gate 3 has higher strength, improves its blocking effect against strong winds or collisions of cattle and sheep, and prolongs its service life.

[0029] The implementation principle of a mining area reciprocating safety door device in the embodiment of the present application is:

[0030] When the car passes through the entrance 1 of the mining area, the gate controller 14 recognizes the vehicle information through the camera, and the gate controller 14 controls the drive motor 11 to rotate clockwise. The drive motor 11 drives the rack 9 and the gate 3 on its upper part to move into the storage box 2 through the rotation of the drive gear 10, and stops at 0.3-0.5 meters from the end of the storage box 2. The drive motor 11 stops rotating, and the gate 3 moves in the opposite direction to close after the vehicle passes (such as Figure 3 shown);

[0031] When the gate 3 moves, the supporting gear 7 at the bottom of the storage box 2 plays a supporting role to prevent the driving teeth 10 of the driving motor 11 from being damaged by force. The metal gate 3 driven by the gear rack mechanism can be pushed and pulled smoothly. The gear rack mechanism has a better anti-erosion effect on grassland wind and sand, which greatly extends the service life of the gate 3 when pushed and pulled. The limit assembly arranged in the storage box 2 and the multiple limit rollers 4 of the limit assembly ensure the horizontal position of the gate 3 when pushed and pulled, which not only ensures the stability of its horizontal movement, but also prevents the gate 3 from being deformed by strong winds or collisions with cattle and sheep, thereby improving the anti-deformation strength of the gate 3.
