Description

Technical field:

[0001] The utility model belongs to the field of mine safety equipment, in particular to a mine auxiliary shaft safety door. Background technology:

[0002] In the production of mining enterprises, mine safety doors are important protective facilities set up to prevent mine cars, personnel and other materials from entering the mine entrance by mistake and causing safety accidents. They are also important components of mine safety protection measures. Existing mine safety doors have different structures, shapes and sizes according to the actual terrain and mine entrance conditions, and there are many types and models. The commonly used safety door in mines is the horizontal sliding safety door, which is mainly composed of a door rail, a horizontal guide rail, a drive motor, a sprocket and a transmission chain. The drive motor drives the transmission chain to pull the door rail along the laid guide rail to open and close the safety door.

[0003] When the safety gate is in use, if the guide rail paving height is higher than the tunnel ground, it is equivalent to installing a height limit frame, which is not convenient for the normal and rapid passage of personnel and logistics; when the guide rail paving height is flush with the ground or lower than the ground, debris will fall into the guide rail groove, resulting in the gate rail not being able to move smoothly in the guide rail. In addition, the air in the tunnel is relatively humid and acidic, and the lubricating oil on the sprocket and transmission chain is often missing, resulting in severe rust and wear, causing the equipment to work without lubrication, which is prone to disconnection and affects the normal operation of the mine. Utility model content:

[0004] The purpose of the utility model is to provide a mine auxiliary shaft safety door, and overcome the deficiencies of the above-mentioned prior art, and effectively solve the existing problems in the use of traditional safety doors.

[0006] Furthermore, the screw oiling assembly includes an oil storage box, which is fixedly mounted on the top wall of the slider, a refueling pipe is installed on the top wall of the oil storage box, and an oil dripping pipe is connected to the inner wall of the oil storage box, and the dripping port of the oil dripping pipe faces the bidirectional screw.

[0007] Furthermore, an inspection port is provided on the top wall of the hood, a cover plate is provided on the inspection port, and the cover plate is hinged to the top wall of the hood.

[0008] Furthermore, a sealing plug is installed at the top opening of the refueling pipe.

[0010] Furthermore, a rubber block is installed on the inner end side wall of the door rail.

[0011] Furthermore, a reflective warning strip is installed on the outer side wall of the hood.

[0012] The beneficial effects of the utility model are as follows: the door railing can be driven to move horizontally by the bidirectional lead screw, thereby realizing the opening and closing of the safety door of the mine auxiliary shaft, facilitating the normal and rapid passage of personnel and logistics; at the same time, the bidirectional lead screw can be continuously oiled and protected by the lead screw oiling assembly to avoid rust and ensure the normal operation of the mine.

Specific implementation method:

[0017] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation of the present invention is now described with reference to the accompanying drawings:

[0018] like Figures 1 to 3As shown, a mine auxiliary shaft safety door comprises a hood 1, in which a bidirectional lead screw 2 is arranged in the inner cavity of the hood 1, two ends of the bidirectional lead screw 2 are rotatably connected to the two ends of the hood 1, one end of the bidirectional lead screw 2 is transmission connected to a drive motor 3, and the drive motor 3 is fixedly mounted on the hood 1, and sliders 4 are transmission connected to the two sections of the thread of the bidirectional lead screw 2, and the two side walls of the slider 4 are slidingly fitted with the two inner side walls of the hood 1, and a connecting rod 5 is vertically installed at the bottom end of the slider 4, and the bottom end of the connecting rod 5 is fixedly connected to a gate rail 6, and a lead screw oiling assembly is arranged on the slider 4, and the bottom end of the connecting rod 5 is fixedly connected to the inner end top wall of the gate rail 6, a rubber block 12 is installed on the inner end side wall of the gate rail 6, and a reflective warning strip is installed on the outer side wall of the hood 1.

[0019] Specifically, the door rail 6 can be driven to move horizontally by the bidirectional lead screw 2, thereby realizing the opening and closing of the safety door of the mine auxiliary shaft, and facilitating the normal and rapid passage of personnel and logistics.

[0020] In actual use, first fix the hood 1 on the door frame of the mine auxiliary shaft passage, start the drive motor 3 to drive the bidirectional screw 2 to rotate forward, so that the sliders 4 connected on the two sections of the thread of the bidirectional screw 2 are close to each other, the two door fences 6 are close to each other, and the mine auxiliary shaft passage is closed; when the bidirectional screw 2 rotates backward, the sliders 4 connected on the two sections of the thread of the bidirectional screw 2 are away from each other, the two door fences 6 are away from each other, and the mine auxiliary shaft passage is opened, facilitating the normal and rapid passage of personnel and logistics; the rubber block 12 avoids collision damage caused by the two door fences 6 approaching each other, thereby extending their service life.

[0021] like Figures 1 to 3 As shown, a mine auxiliary shaft safety door, the screw oiling assembly includes an oil storage box 7, the oil storage box 7 is fixedly mounted on the top wall of the slider 4, a refueling pipe 8 is installed on the top wall of the oil storage box 7, an oil dripping pipe 9 is connected to the inner wall of the oil storage box 7, the dripping mouth of the oil dripping pipe 9 faces the bidirectional screw 2, an inspection port 10 is opened on the top wall of the hood 1, a cover plate 11 is arranged on the inspection port 10, the cover plate 11 is hinged to the top wall of the hood 1, and a sealing plug is installed at the top opening of the refueling pipe 8.
