Description

Technical Field

[0001] This utility model relates to the field of coal mine safety production technology, specifically to a coal mine track brake. Background Technology

[0002] In the coal mining industry, the use of tracks for material transportation is becoming increasingly common. For example, in the monorail transportation system used underground in coal mines, whether the transportation equipment runs on ground rails or overhead monorails, track brakes must be installed on the tracks for safety reasons.

[0003] As disclosed in the prior art, CN219446997U, a portable level roadway car stopper for coal mine tracks effectively solves the problem of mine cars easily slipping and their length being unable to be adjusted. It includes a fixed plate with two opposing stopping blocks slidably connected to it. A lifting plate is provided above the fixed plate, and connecting rods are hinged to the left and right sides of the lifting plate. The lower end of the connecting rod is hinged to the corresponding stopping block. Connecting blocks are fixedly connected to the left and right sides of the upper end of the fixed plate. The connecting blocks are hinged to the corresponding connecting rods via a balance rod. Multiple limiting grooves are provided on the left and right sides of the front end of the fixed plate.

[0004] Most existing rail brakes used in coal mines adopt a structure in which the rail brake is fixedly installed on the rail. The position of the rail brake cannot be flexibly adjusted, and there is a lack of buffer device. This causes a lot of noise when there is a collision, and at the same time, it causes wear and tear on the transport vehicle and the rail brake, reducing their service life.

[0005] Therefore, a rail brake for coal mines is needed. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model provides a coal mine track brake to solve the aforementioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a coal mine track car stopper, comprising a car stopper and a track. The car stopper is disposed on one side of the track to block and limit the movement of coal mine cars. The car stopper includes a fixed plate, a car stop plate, a rotating rod, and a buffer spring. The fixed plate is disposed on one side of the track. Bearing bases are symmetrically arranged on the upper part of the fixed plate. A rotating rod is rotatably installed between the bearing bases. The rotating rod located between the two bearing bases is a polygonal column rod. The rotating rods on both sides of the polygonal column rod are cylindrical columns rods. Car stop plates are sleeved at both ends of the polygonal column rod. The car stop plates are in contact with the end faces of the cylindrical columns rods. A polygonal sleeve is disposed on the side of the polygonal column rod facing the polygonal column rod. A buffer spring is abutted between the two polygonal sleeves and is sleeved on the polygonal column rod. One side of the rotating rod is configured as a bent structure. A telescopic rod is connected to the bent structure through a rotating shaft base one. The bottom of the telescopic rod is installed with the fixed plate through a rotating shaft base two.

[0008] Preferably, the polygonal sleeve has a through hole inside that matches the number of sides of the polygonal column, so that the polygonal sleeve and the polygonal column can slide in a limited manner through the polygonal structure.

[0009] Preferably, the polygonal column has a hexagonal structure with the number of sides.

[0010] Preferably, the side of the polygonal sleeve facing the buffer spring is configured as a baffle, and the buffer spring is installed between the baffles.

[0011] Preferably, the height of the bearing base is at least 1 / 3 of the height of the wheel stop plate, so that the wheel stop plate can be easily rotated.

[0012] In summary, this utility model provides a coal mine track brake. This utility model patent realizes that the polygonal column partially limits and drives the brake plate to rotate toward the track, so that the brake plate is placed on the track; since the two sides of the rotating rod are set as cylindrical column structures, the cylindrical column limits and installs the brake plate.

[0013] A buffer spring is installed between the polygonal sleeves. During the blocking process, due to the force applied by the coal mine transportation equipment, the blocking plate drives the polygonal sleeves to slide on the polygonal column. The reaction force of the buffer spring provides buffering force to the blocking plate, thereby increasing the buffering and noise reduction during the blocking process. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figures 1 to 2 As shown:

[0019] This utility model relates to a coal mine track car stopper, comprising a car stopper 1 and a track 2. The car stopper 1 is disposed on one side of the track 2 to block and limit the movement of coal mine cars. The car stopper 1 includes a fixed plate 3, a car stop plate 4, a rotating rod 5, and a buffer spring 6. The fixed plate 3 is disposed on one side of the track 2, and bearing bases 7 are symmetrically arranged on the upper part of the fixed plate 3. A rotating rod 5 is rotatably mounted between the bearing bases 7. The rotating rod 5 located between the two bearing bases 7 is a polygonal column rod 11, and the rotating rods 5 on both sides of the polygonal column rod 11 are cylindrical columns. 12. Both ends of the polygonal column 11 are fitted with a car-stopping plate 4. The car-stopping plate 4 contacts the end face of the cylindrical column 12. A polygonal sleeve 13 is provided on the side of the polygonal column 11 facing the polygonal column 11. A buffer spring 6 is installed between the two polygonal sleeves 13. The buffer spring 6 is fitted on the polygonal column 11. One side of the rotating rod 5 is set as a bent structure. The bent structure is connected to the telescopic rod 15 through the rotating shaft base 14. The bottom of the telescopic rod 15 is installed with the fixing plate 3 through the rotating shaft base 2 16.

[0020] To address the limitations of existing technologies, such as the fixed installation of the wheel stopper 1 and track 2, which restricts the flexible blocking of coal mine transport equipment and limits its application scenarios, and the resulting collisions and noise pollution between the wheel stopper 1 and the transport equipment, leading to significant equipment wear and site noise, this utility model patent employs the following structure: A wheel stopper 1 is installed on one side of the track 2. During use, a telescopic rod 15 drives a rotating rod 5 to rotate towards the track 2. The middle of the rotating rod 5 is a polygonal column rod 11 structure, and the bottom of the wheel stopper plate 4 has a polygonal opening to match the polygonal column rod 11 structure. Due to the polygonal structure, the polygonal column rod 11 partially limits and drives the wheel stopper plate 4 to rotate towards the track 2, placing the wheel stopper plate 4 on the track 2. The two sides of the rotating rod 5 are set with cylindrical column rods 12 structures, which limit the installation of the wheel stopper plate 4.

[0021] To achieve buffering during the blocking of coal mine transport equipment by the wheel stop plate 4, thereby reducing noise and collision wear, polygonal sleeves 13 are respectively fitted on both sides of the polygonal column 11. A buffer spring 6 is installed between the polygonal sleeves 13. During the blocking process, due to the force applied by the coal mine transport equipment, the wheel stop plate 4 drives the polygonal sleeves 13 to slide on the polygonal column 11. The reaction force of the buffer spring 6 provides buffering force to the wheel stop plate 4, thereby increasing the buffering and noise reduction during the blocking process.

[0022] Similarly, the telescopic rod 15 drives the rotating rod 5 to rotate away from the track 2, which in turn drives the car stop plate 4 to rotate away from the track 2, thereby removing the obstruction restriction on the track 2. This allows for flexible obstruction and solves the inconvenience and limitations of fixed installation.

[0023] In at least one embodiment, in order to achieve smooth buffering of the vehicle stop plate 4, the structure is as follows: the polygonal sleeve 13 has through holes 17 inside that match the number of sides of the polygonal column 11, so that the polygonal sleeve 13 and the polygonal column 11 can slide in a limited manner through the polygonal structure.

[0024] In at least one embodiment, the polygonal column 11 is configured with a hexagonal structure.

[0025] In at least one embodiment, in order to achieve the limiting installation of the polygonal sleeve 13 on the buffer spring 6 during buffering use, the structure is as follows: the side of the polygonal sleeve 13 facing the buffer spring 6 is set as a baffle 21, and the buffer spring 6 is installed between the baffles 21.

[0026] In at least one embodiment, to facilitate the rotational installation of the wheel stop plate 4, a certain height is reserved between it and the fixing plate 3. The structure is such that the height of the bearing base 7 is at least 1 / 3 times the height of the wheel stop plate 4, so that the wheel stop plate 4 can be easily rotated.

[0027] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
