[0025] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0026] like Figure 1 and Figure 2 As shown, the embodiment of the present disclosure proposes a self-locking track wheel stopper, including: an iron shoe body 1 and a track clamping device 2, the iron shoe body 1 is arranged on the top of the rail head of the track 3, the track clamping device 2 includes: a first buckle 21, a second buckle 22, a drive switch 23 and a reset spring 24, the first buckle 21 and the second buckle 22 are respectively rotatably arranged on both sides of the iron shoe body 1, and the drive switch 23 is slidably arranged on the iron shoe body 1, the drive switch 23 is respectively connected to the first buckle 21 and the second buckle 22 by transmission, and the reset spring 24 is arranged between the drive switch 23 and the iron shoe body 1. Among them, the reset spring 24 is used to reset the drive switch 23 to the first position, so that the drive switch 23 drives the first buckle 21 and the second buckle 22 to clamp the bottom of the rail head of the track 3, and when the drive switch 23 moves from the first position to the second position, the drive switch 23 is used to drive the first buckle 21 and the second buckle 22 to release the bottom of the rail head of the track 3.

[0027] It can be understood that since the reset spring 24 is arranged between the drive switch 23 and the iron shoe body 1, the drive switch 23 can be moved to the first position by utilizing the reset of the reset spring 24, and since the first buckle 21 and the second buckle 22 are respectively rotatably arranged on both sides of the iron shoe body 1 and the drive switch 23 is slidably arranged on the iron shoe body 1, and the drive switch 23 is respectively connected to the first buckle 21 and the second buckle 22 by transmission, so that when the drive switch 23 moves to the first position, it can respectively drive the first buckle 21 and the second buckle 22 to rotate, thereby clamping the bottom of the rail head of the rail 3, and, when the drive switch 23 moves from the first position to the second position, it can respectively drive the first buckle 21 and the second buckle 22 to rotate, thereby releasing the bottom of the rail head of the rail 3.

[0028] Therefore, by utilizing the self-locking function of the track-locking device 2, the iron shoe body 1 is stably arranged on the track 3, avoiding the problem of the iron shoe body 1 falling due to vibration, wheel push, etc., thereby ensuring the effective stopping of the vehicle by the iron shoe body 1, and further realizing the safe operation of the vehicle on the track 3.

[0029] It should be noted that the iron shoe body 1 is used to prevent the wheel from rolling and prevent the vehicle from slipping. The specific type of the iron shoe body 1 can be set according to actual needs and is not limited to this.

[0030] The track 3 is an I-shaped structure, the top of the track 3 is the track head, the bottom is the track bottom, the middle is the track waist, the iron shoe body 1 is placed on the top of the track head, and the first buckle 21 and the second buckle 22 are clamped at the bottom of the track head.

[0031] The track-locking device 2 is used to be arranged on the iron shoe body 1 to lock the iron shoe body 1 on the track 3, thereby avoiding the problem of falling.

[0032] Among them, the first buckle 21 is used to cooperate with the second buckle 22 to realize the clamping of the iron shoe body 1 on the rail head of the track 3. The specific type of the first buckle 21 can be set according to actual needs and is not limited to this. For example, the first buckle 21 can be a structure close to a C-shape, and the middle part of the first buckle 21 is arranged on the side of the iron shoe body 1 away from the second buckle 22 by rotating the pin shaft.

[0033] The second buckle 22 is used to cooperate with the first buckle 21 to realize the clamping of the iron shoe body 1 on the rail head of the track 3. The specific type of the second buckle 22 can be set according to actual needs and is not limited to this. For example, the second buckle 22 can be a structure close to a C-shape, and the middle part of the second buckle 22 is arranged on the side of the iron shoe body 1 away from the first buckle 21 by rotating with a pin shaft.

[0034] When the first clip 21 and the second clip 22 clamp the bottom of the rail head of the track 3, they can prevent the iron shoe body 1 from tilting to both sides or even falling. However, since the first clip 21 and the second clip 22 only clamp in the width direction of the track 3, they will not affect the sliding of the iron shoe body 1 when it stops.

[0035] The driving switch 23 is used to transmit with the first buckle 21 and the second buckle 22 respectively to realize the clamping action or the releasing action of the first buckle 21 and the second buckle 22. Specifically, the driving switch 23 moves to the first position to drive the first buckle 21 and the second buckle 22 to rotate, thereby clamping the bottom of the rail head of the rail 3, and moves to the second position to drive the first buckle 21 and the second buckle 22 to rotate, thereby releasing the bottom of the rail head of the rail 3. The specific type of the driving switch 23 can be set according to actual needs, and there is no limitation to this.

[0036] The driving switch 23 can be moved from the first position to the second position manually or electrically, and there is no limitation to this.

[0037] The reset spring 24 is used to reset the drive switch 23 to the first position to realize the self-locking function of the track wheel stopper. The specific type of the reset spring 24 can be set according to actual needs and is not limited to this. Among them, the reset spring 24 can be set to multiple to achieve uniform force on the drive switch 23.

[0038] Track wheel stoppers also play a braking role in rail traffic. In marshalling yards, section stations and other places, when shunting operations are required, track wheel stoppers are used as a braking tool. The track wheel stoppers are placed in front of the wheels manually or mechanically. When the wheels roll and press on the track wheel stoppers, the braking surface of the track wheel stoppers contacts the wheel tread and generates sliding friction, causing the vehicle to quickly slow down and eventually stop. This braking method not only reduces the labor intensity of the brake personnel, improves shunting efficiency, but also enhances personal safety.
