Description

Technical Field

[0001] The utility model belongs to the technical field of mine vehicles, and in particular relates to a safety protection device for a coal mine transport vehicle. Background Art

[0002] The trolleys used to transport coal in coal mines are usually called mine cars or mine trolleys. These trolleys are usually used to transport coal on the coal mine roads inside the mine to transport coal from the coal mining face to the coal unloading point or processing facility. Mine cars are usually track-type or tire-type, with a small loading capacity, suitable for running in the narrow passages of the mine. They can be pushed manually or driven by electricity to load and unload coal as needed.

[0003] In the existing technology, since the mine car is installed on the chassis in an articulated manner during use, when the mine car is full of coal, the traction equipment drives the mine car to move and transport the coal to a suitable location. However, during the movement of the mine car, it may be inconvenient to flip and adjust the baffles installed on both sides of the top of the mine car to fit the coal, and it is also inconvenient to limit the position of the baffles after adjustment, which may cause the ore on the top of the mine car to roll down, thereby greatly increasing the danger in the process of coal transportation;

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0008] Preferably, a first magnet is fixedly connected to the side of the annular plate away from the positioning rod, and the inner circumference of the first magnet is larger than the outer circumference of the movable rod. A second magnet is fixedly connected to the inner wall of the sleeve block, and a fitting groove matching the first magnet is provided on the second magnet. The magnetic poles of the adjacent sides of the first magnet and the second magnet are opposite.

[0009] By providing the first magnet, the second magnet and the fitting groove, the positioning block is firmly fixed inside the positioning groove.

[0010] Preferably, one end of the movable rod away from the first ear plate is fixedly connected to a turntable, and an anti-slip groove is provided on the turntable.

[0011] By arranging the rotating disk and the anti-skid groove, it is possible to facilitate the movable rod to drive the lateral baffle to rotate.

[0012] Preferably, an outer side wall of the sleeve block is fixedly connected with an anti-collision pad, and an inner side wall of the anti-collision pad is in contact with the outer side of the top of the mining car body.

[0014] Preferably, an extension plate is fixedly connected to the top of the mining car body, and the outer side wall of the extension plate is in contact with the outer side wall of the lateral baffle.

[0015] By setting the extension plate, the height of the rear baffle of the mine car body is avoided.

[0016] Preferably, a lifting ring seat is installed on the outer side wall of the mining car body, and a hanging ring is fixedly connected to the lifting ring seat.

[0017] By arranging the lifting ring seat and the hanging ring, the movement of the mine car body is facilitated.

[0018] To sum up, the technical effects and advantages of the utility model are as follows: the safety protection device of the coal mine transport vehicle adjusts the angle of the lateral baffle through the coordinated use of the first ear plate, the second ear plate and the movable rod, and facilitates the movement and adjustment of the annular plate through the coordinated use of the positioning rod and the movable plate, and then positions the movable rod after rotation through the coordinated use of the positioning groove and the positioning block, thereby limiting the positioning of the lateral baffle after flipping, thereby preventing coal on the top of the mine car body from rolling down from both sides during the movement of the mine car body.

[0019] The first magnet and the second magnet are used in combination to stabilize the positioning block in the positioning groove, and the lifting ring seat and the hanging ring are used in combination to facilitate the movement of the mine car body on the track, thereby preventing the lateral baffle from flipping over during the movement of the mine car body.

[0032] Working principle: First, the wire rope on the traction equipment is connected to the mine car body 1 through the lifting ring seat 17 and the hanging ring 18, so that the mine car body 1 can move on the guide rail. After the mine car body 1 moves to the mining area under the mine, the mined coal is put into the mine car body 1, and the coal inside the mine car body 1 is slowly piled up. After the coal fills the interior of the mine car body 1, the turntable 14 and the anti-skid groove 15 drive the movable rod 4 to rotate, and the lateral baffle 19 flips upward accordingly, so that the lateral baffle 19 is in contact with the coal piled on the top of the mine car body 1, and the anti-collision pad 16 is in contact with the top of the mine car body 1. The movable plate 9 and the positioning rod 8 drive the annular plate 7 to move in the direction close to the sleeve block 5, and the positioning block 10 moves to the inside of the positioning groove 6.
