Description

Technical Field

[0001] This utility model provides a rail wheel with a parking brake device, belonging to the field of rail wheel parking brake technology. Background Technology

[0002] Track wheels are devices used to roll on tracks and are widely used in equipment such as conveyor systems, automated production lines, cranes, and gate control systems. Their main function is to guide and support moving parts, ensuring that they move smoothly and accurately along a predetermined path.

[0003] However, the traditional foot-operated braking device used in track wheels needs to be welded to the track wheel support frame later and uses physical friction for braking. During use, the device needs to step out of the track wheel a certain distance to achieve braking. The braking device is very easy to be damaged during handling and loading and unloading, resulting in a high maintenance and replacement rate. Sometimes, insufficient friction force can also cause the vehicle to slip. Utility Model Content

[0004] The technical problem this invention aims to solve is that track wheels are prone to slipping when parked.

[0005] To solve the above problems, the present invention proposes the following technical solution: a track wheel with a parking brake device, comprising a wheel body, two sides of the wheel body being rotatably mounted on the lower part of a mounting frame via a rotating shaft, and a parking brake mechanism being provided on one side of the rotating shaft and the mounting frame; the parking brake mechanism includes a clamping plate with a through hole in the middle of the rotating shaft, a fixing plate that slides up and down in the middle of a thick side plate and is located outside the clamping plate, and a positioning plate that is rotatably connected to the upper end of the fixing plate.

[0006] As an improvement, the shaft rotates synchronously with the wheel body, and one end of the shaft passes through the mounting bracket and through a partially flattened part with a through hole;

[0007] As an improvement, the mounting bracket includes side plates that are rotatably connected to the rotating shaft, a top plate located at the upper middle part of the two side plates, and the side plate near the through hole is thicker than the other side plate.

[0008] As an improvement, the inside of the fixing plate is provided with T-shaped holes. The upper part of the T-shaped holes corresponds to the card plate and the lower part corresponds to the rotating shaft. The two sides of the fixing plate are connected to the inside of the thick side plate by high-strength tension springs.

[0009] As an improvement, the upper part of the positioning plate is hook-shaped.

[0010] The beneficial effects of this utility model are:

[0011] By rotating the wheel body on the lower part of the mounting bracket via a pivot, and installing a parking brake mechanism on one side of the pivot and the mounting bracket, the pivot can be fixed by the parking brake mechanism, thereby fixing the wheel body and preventing the wheel body from rotating, thus preventing the vehicle from slipping.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] according to Figure 1 As shown in Figure 2: This utility model provides a track wheel with a parking brake device: it includes a wheel body 1, and the two sides of the wheel body 1 are respectively rotatably mounted on the lower part of the mounting frame 3 via a rotating shaft 2. A parking brake mechanism 4 is provided on one side of the rotating shaft 2 and the mounting frame 3. By rotatably mounting the wheel body 1 on the lower part of the mounting frame 3 via the rotating shaft 2, and providing a parking brake mechanism 4 on one side of the rotating shaft 2 and the mounting frame 3, the rotating shaft 2 can be fixed by the parking brake mechanism 4, thereby fixing the wheel body 1 and preventing the wheel body 1 from rotating, thus preventing the vehicle from slipping.

[0017] The rotating shaft 2 rotates synchronously with the wheel body 1. One end of the rotating shaft 2 passes through the mounting bracket 3 and is partially flattened with a through hole 201. In this way, the wheel body 1 can be fixed by fixing the rotating shaft 2.

[0018] The mounting bracket 3 includes side plates 301 that are rotatably connected to the rotating shaft 2, and a top plate 302 located at the upper middle part of the two side plates 301. The side plate 301 near the through hole 201 is thicker than the other side plate 301. In this way, the rotating shaft 2 on both sides of the wheel body 1 can rotate at the lower part of the two side plates 301.

[0019] The parking brake mechanism 4 includes a clamping plate 401 with a through hole 201 in the middle of a rotating shaft 2, a fixing plate 402 that slides up and down in the middle of a thick side plate 301 and is located outside the clamping plate 401, and a positioning plate 403 that is rotatably connected to the upper end of the fixing plate 402. The fixing plate 402 has a T-shaped hole 4021 inside, with the upper part of the T-shaped hole 4021 corresponding to the clamping plate 401 and the lower part corresponding to the rotating shaft 2. Both sides of the fixing plate 402 are connected to the inner sides of the thick side plate 301 by high-strength tension springs. The upper part of the positioning plate 403 is hook-shaped. The design of the positioning plate 403 makes it easy for personnel to lift, thereby raising the clamping plate 401 and opening the T-shaped hole. The lower part of 4021 is located outside the clamping plate 401. Then, the positioning plate 403 is rotated so that the two sides of the positioning plate 403 rest on the side plate 301 and the top plate 302. This will not affect the rotation of the wheel 1. When parking is required, the two sides of the positioning plate 403 and the two sides of the fixing plate 402 are respectively on the same plane. Then, under the action of the high-strength tension spring, the fixing plate 402 and the positioning plate 403 will be pulled down. When the rotating shaft 2 and the wheel 1 rotate at the same time, the clamping plate 401 will also rotate. When in a vertical state, the positioning plate 402 will move down so that the upper part of the T-shaped hole 4021 is clamped on the clamping plate 401, thereby fixing the rotating shaft 2 and then fixing the wheel 1.

[0020] The principle of this utility model is as follows: When parking is required, the two sides of the positioning plate 403 and the two sides of the fixing plate 402 are respectively on the same plane. Under the action of the high-strength tension spring, the fixing plate 402 and the positioning plate 403 will be pulled downward. When the rotating shaft 2 and the wheel 1 rotate simultaneously, the clamping plate 401 will also rotate. When in a vertical state, the positioning plate 402 will move downward, so that the upper part of the T-shaped hole 4021 is clamped on the clamping plate 401, thereby fixing the rotating shaft 2 and then fixing the wheel 1 to achieve parking.

[0021] When the wheel 1 needs to rotate, lift the positioning plate 403, thereby raising the clamping plate 401 so that the lower part of the T-shaped hole 4021 is on the outside of the clamping plate 401. In this way, the T-shaped hole 4021 will not affect the rotation of the clamping plate 401. Then rotate the positioning plate 403 so that the two sides of the positioning plate 403 rest on the side plate 301 and the top plate 302, so that the wheel 1 can rotate.

[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
