Description

Technical Field

[0001] This utility model relates to the field of wheel movement limiting equipment technology, and in particular to a novel tire movement limiting structure. Background Technology

[0002] Wheel limiters are a common type of tire restraint device for trucks, used to secure and prevent slippage during loading and unloading. Traditional wheel limiters often suffer from problems such as complex structure, inconvenient installation, and insufficient stability. Furthermore, in some cases, they are only suitable for one type of truck, affecting loading and unloading efficiency.

[0003] To address the aforementioned issues, Chinese patent CN 222452185 U discloses a wheel truck wheel limiter that uses a combination of a limiting device and a blocking device to hold the tire between them. The limiting device has a gear-locking component, and opening and closing are achieved through a tension spring. However, the blocking device in this patent is a low-angle inclined surface. When loading and unloading goods, the vehicle will make a small back-and-forth movement on the inclined surface due to unstable gravity changes, causing the vehicle to sway and creating a safety hazard during loading and unloading.

[0004] Chinese patent CN 220842494 U discloses a truck wheel limiter, which is similar to the aforementioned patent technology. The obvious difference is that this patent places the locking rod and drive trigger component on the front and rear sides of the tire, which has a more obvious limiting effect on the tire. However, it is also fixed by a similar buckle, which may loosen after long-term use. Utility Model Content

[0005] To address the problem of poor tire movement limiting effect in existing limiters, this utility model provides a novel tire movement limiting structure, including a fixed base, a limiting device, and a front drive lock. The fixed base is a long strip-shaped channel steel with a triangular lifting platform connected to one end. A sliding bracket is arranged parallel inside, and a reciprocating front drive plate and a rear drive plate are mounted on the sliding bracket. A valve is fixed to each of the front and rear drive plates, and the front and rear drive plates are connected by a telescopic spring. The limiting device is gourd-shaped, and its cavity is adapted to the shape of the lifting platform. The limiting device is connected to the rear drive plate via a rotating column. A limiting rod is provided on the limiting device, perpendicular to the side of the fixed base, and fitted with two triangular protective brackets. The front drive lock is triangular, with a pulley on its base, and is fixed to the side wall of the front drive plate, on the same side as the limiting rod.

[0006] Compared to existing limiters, the advantages of this tire movement limiting structure are its simpler structure, easier installation, higher stability, and interchangeable left and right installation, resulting in better applicability. Through the cooperation of the front-drive locking device and the limiting device, this invention effectively prevents tire swaying during loading and unloading, improving the safety and efficiency of cargo handling. Simultaneously, the design of the front and rear drive plates allows this limiting structure to be applied to various vehicle models, increasing its practicality and applicability. Furthermore, the triangular protective frame further enhances the stability and safety of the limiting rod, preventing loosening that may occur after prolonged use and extending the equipment's service life.

[0007] The retaining valve in this tire movement limiting structure is controlled by an electrical signal. After the vehicle comes to a complete stop, the retaining valve is locked, which can further enhance the tire movement limiting effect.

[0008] Furthermore, a micro-motion detector is fixed to the front drive panel. This detector can detect minute tire displacements and trigger an alarm, allowing for manual protective measures and increasing the safety of the tire-limiting structure.

[0009] Furthermore, anti-overdrive pillars are provided on the front and rear drive plates. In this invention, before the vehicle comes to a complete stop, the front and rear drive plates are linked by telescopic springs to ensure that the limit rod and the front drive lock are always in contact with the tire surface. After the vehicle comes to a complete stop, the brake is activated to completely fix the tire. Therefore, in order to prevent the telescopic springs from being overstretched and losing their elasticity, causing the limit rod to detach from the tire surface, anti-overdrive pillars are provided.

[0010] Furthermore, the sliding bracket is provided with several slots, and a circular hole plate is fixed on the front drive plate. The circular holes of the circular hole plate are horizontal with the slots, and the slots are fitted with inserts. This design allows for manual operation when the micro-motion detector detects tire displacement or brake failure. The insert is passed through the slot and then inserted into the circular hole of the circular hole plate to manually limit tire movement. Attached Figure Description

[0018] The present invention will be described below with reference to examples. The examples are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0019] like Figures 1-3 As shown, this utility model provides a novel tire movement limiting structure, including a fixed base 1, a limiting device 2, and a front drive lock 3. The fixed base 1 is a long strip-shaped channel steel, with a triangular lifting platform 11 connected to one end. A sliding bracket 12 is arranged parallel inside. A reciprocating front drive plate 13 and a rear drive plate 14 are arranged on the sliding bracket 12. A retaining valve 15 is fixed to the front drive plate 13 and the rear drive plate 14 respectively. The retaining valve 15 is connected to the control center through a wire. The front drive plate 13 and the rear drive plate 14 are connected by a telescopic spring 16. A micro-motion detector 17 is fixed on the front drive plate 13. Nuts are fixed to the front drive plate 13 and the rear drive plate 14 respectively. The nut holes are horizontally opposite and are adapted to anti-over-pull posts 18. Nuts are provided at both ends of the anti-over-pull posts 18. The sliding bracket 12... The front drive plate 13 is provided with several slots 19. A circular hole plate is fixed on the front drive plate 13. The circular holes of the circular hole plate are horizontal with the slots 19. The slots 19 are adapted to inserts 110. The limiting device 2 is gourd-shaped. Its cavity is adapted to the shape of the lifting platform 11. The limiting device 2 is connected to the rear drive plate 14 through a rotating column 21. The limiting device 2 is provided with a limiting rod 22. The limiting rod 22 is perpendicular to the side of the fixed base 1. The limiting rod 22 is adapted to two triangular protective frames 23. The right angles of the two triangular protective frames 23 are set facing each other with a gap in the middle. When the limiting device 2 covers the lifting platform 11, the limiting rod 22 is just embedded in the gap. The front drive lock 3 is triangular and has a pulley on the bottom surface. The front drive lock 3 is fixed on the side wall of the front drive plate 13 and is on the same side as the limiting rod 22.

[0020] like Figure 4 The diagram shows the state of the tire movement limiting structure of this utility model. Before the tire enters, the limiting rod 22 is in the gap between the two triangular protective frames 23. As the tire enters, it pushes the front drive locking device 3 forward, and the linked limiting device 2 is also lifted along the lifting platform 11. The limiting rod 22 moves up from the gap and fits against the tire. As the tire stops at the designated position, the control center controls the holding valve 15 to lock, completely fixing the tire.

[0021] like Figure 5As shown, the valve 15 is fitted into the sliding bracket 12, and the contact surface is corrugated to increase friction. The valve 15 is equipped with a pneumatic rod, which is connected to the control center via electrical signal. After the tire stops, the pneumatic rod is activated, causing the valve 15 to grip the sliding bracket 12 tightly. After loading and unloading are completed, the pneumatic rod is released, and the tire drives the limit rod 22 into the gap of the protective frame 23, thus driving out.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
