Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary equipment for semi-trailer maintenance, and in particular to a semi-trailer tire installation positioning guide device. Background Technology
[0002] Semi-trailers are an important means of transportation and are widely used in the logistics and transportation industry. As a key component of semi-trailers, the quality of their installation directly affects the driving safety of the semi-trailer. During the replacement or repair of semi-trailer tires, it is necessary to accurately install the tires onto the wheel rims.
[0003] A tooling for installing axles and tires of a semi-trailer, disclosed in Chinese Patent Publication No. CN203031222U, eliminates the need for workers to work under the semi-trailer, thus eliminating safety hazards. Furthermore, the axle installation process does not require workers to lift the axle, reducing their workload and improving work efficiency.
[0004] Because semi-trailer tires are large and heavy, traditional tire installation methods mainly rely on manual positioning. This method is not only labor-intensive, but also makes it difficult to achieve precise tire alignment, which can easily lead to tire misalignment. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a semi-trailer tire mounting and positioning guide device, which solves the problems mentioned in the background.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a semi-trailer tire mounting and positioning guide device, comprising a bracket, with a first slot and a second slot respectively opened at both ends of the bracket. A first groove is symmetrically opened on the inner wall of the first slot, with one side of the first groove penetrating the bracket. A second groove is symmetrically opened on the inner wall of the second slot. An electric guide rail is fixedly connected to one side of each of the first and second grooves. A first slider and a second slider are fixedly connected to the movable ends of the two second grooves respectively, with one end of the first slider engaging with the first groove penetrating the bracket. A through hole is opened above both the first and second sliders, and a movable rod is installed in the through hole. A first clamping pad is detachably connected to one end of each movable rod that is close to the other. A foot-operated hydraulic rod is fixedly connected to the middle of the bracket. A second clamping pad is fixedly and detachably connected to the movable end of the movable rod. A compression spring is fitted onto the surface of one movable rod located between the first clamping pad and the first slider, and onto the surface of the other movable rod located between the first clamping pad and the second slider. A tire is engaged between the second clamping pad and the two first clamping pads.
[0007] As a further technical solution of this utility model, a threaded ring is fixedly connected to one end of the first clamping pad near the inner wall of the bracket, and the surface of the movable rod near the first clamping pad is provided with threads, and the movable rod is threadedly connected to the threaded ring. The installation method of the second clamping pad and the hydraulic rod is the same as the installation method of the first clamping pad and the movable rod.
[0008] As a further technical solution of this utility model, a U-shaped plate is fixedly connected to the end of the first slider near the tire at the bottom. A roller is rotatably connected to the inner wall of the U-shaped plate through a first rotating shaft, and the outer surface of the roller is in contact with the surface of the tire.
[0009] As a further technical solution of this utility model, the side end of the first slider is rotatably connected to a second rotating shaft at a horizontal position with the first rotating shaft. Both the surface of the first rotating shaft and the second rotating shaft are fitted with belt pulleys, and the two belt pulleys are connected by a belt.
[0010] As a further technical solution of this utility model, a support plate located outside the first slide groove is fixedly connected to the side end of the first slider, and a servo motor is fixedly connected to the support plate, and the output end of the servo motor is connected to the second rotating shaft.
[0011] As a further technical solution of this utility model, both the first clamping pad and the second clamping pad are made of silicone material.
[0012] As a further technical solution of this utility model, a controller for controlling the electric guide rail and the servo motor is fixedly connected on the bracket.
[0013] This utility model provides a semi-trailer tire mounting and positioning guide device, which has the following advantages compared with the prior art:
[0014] This design discloses a semi-trailer tire installation positioning and guiding device. The tire is first placed between two first clamping pads, with its bottom resting on a second clamping pad. The two first clamping pads, driven by compression springs, extend and retract a movable rod to position it against the tire surface. Then, a foot-operated hydraulic rod is used to adjust the tire's vertical position, aligning it with the installation position on the semi-trailer. Simultaneously, a controller activates an electric guide rail, driving a first and second slider, which in turn moves the two first clamping pads along with the tire. During the movement of the first slider, a servo motor and rollers also move, ensuring the rollers' surface remains in contact with the tire surface. During tire installation, the controller activates a servo motor to slowly rotate a second rotating shaft, which, via a belt and pulley, synchronously rotates the first rotating shaft, driving the rollers to rotate slowly. This indirectly causes the tire to rotate between the two clamping pads, adjusting the position of the mounting hole. This technical solution automatically adjusts the tire's position, ensuring precise alignment with the installation position on the semi-trailer, reducing labor costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-3This utility model provides a technical solution for a semi-trailer tire installation positioning and guiding device: It includes a bracket 1, with a first slot 2 and a second slot 5 respectively opened at both ends of the bracket 1. The inner wall of the first slot 2 is symmetrically provided with first grooves 3, one of which penetrates the bracket 1. The inner wall of the second slot 5 is symmetrically provided with second grooves 4. An electric guide rail 6 is fixedly connected to one side of each of the first and second grooves 3 and 4. A first slider 7 and a second slider 8 are fixedly connected to the movable ends of the two second grooves 4 respectively, with one end of the first slider 7 engaging with the first groove 3 penetrating the bracket 1. Both 7 and the second slider 8 have through holes, and movable rods 15 are installed in the through holes. The two movable rods 15 are detachably connected to the first clamping pads 14 at one end close to each other. A foot pedal hydraulic rod 17 is fixedly connected to the middle of the bracket 1. The movable end of the movable rod 15 is fixedly and detachably connected to the second clamping pad 18. A compression spring 16 is sleeved on the surface of one movable rod 15 located between the first clamping pad 14 and the first slider 7, and on the surface of the other movable rod 15 located between the first clamping pad 14 and the second slider 8. A tire 13 is engaged between the second clamping pad 18 and the two first clamping pads 14.
[0022] Please see Figure 4 The first clamping pad 14 is fixedly connected to a threaded ring 22 at one end near the inner wall of the bracket 1. The movable rod 15 is threaded at one end near the first clamping pad 14 and is threadedly connected to the threaded ring 22. The second clamping pad 18 and the hydraulic rod 17 are installed in the same way as the first clamping pad 14 and the movable rod 15. Both the first clamping pad 14 and the second clamping pad 18 are made of silicone.
[0023] Please see Figure 2 A U-shaped plate 19 is fixedly connected to the lower end of the first slider 7 near the tire 13. A roller 21 is rotatably connected to the inner wall of the U-shaped plate 19 via a first rotating shaft 20, and the outer surface of the roller 21 is in contact with the surface of the tire 13. A second rotating shaft is rotatably connected to the side end of the first slider 7 at a horizontal position with the first rotating shaft 20. Both the surface of the first rotating shaft 20 and the second rotating shaft are fitted with belt pulleys 12, and the two belt pulleys 12 are connected by a belt 11. A support plate 9 located outside the first slide groove 3 is fixedly connected to the side end of the first slider 7. A servo motor 10 is fixedly connected to the support plate 9, and the output end of the servo motor 10 is connected to the second rotating shaft. A controller for controlling the electric guide rail 6 and the servo motor 10 is fixedly connected to the bracket 1.
[0024] The working principle of this utility model is as follows: The tire 13 is first placed between two first clamping pads 14, with its bottom resting on a second clamping pad 18. At this time, the two first clamping pads 14, through the elastic force of the compression spring 16, drive the movable rod 15 to extend and retract, adjusting it to contact and position it against the surface of the tire 13. The contact between the first clamping pads 14 and 18 and the surface of the tire 13 does not affect the subsequent rotation of the tire 13. Then, by stepping on the hydraulic rod 17, the tire 13 is adjusted vertically to align with its installation position on the semi-trailer. Simultaneously, the controller activates the electric guide rail 6, driving the first slider 7 and the second slider 8, which in turn move the two first clamping pads 14 along with the tire 13. During the adjustment of the first slider 7, the servo motor 10 and the roller 21 also move accordingly. This ensures that the surface of roller 21 is always in contact with the surface of tire 13. During tire 13 installation, the servo motor 10 can be activated by the controller to drive the second shaft to rotate slowly. This, in turn, drives the first shaft 20 to rotate synchronously via belt 11 and belt pulley 12, thereby driving roller 21 to rotate slowly. This indirectly drives tire 13 to rotate between the two first clamping pads 14 and the second clamping pad 18 to adjust the position of the mounting hole. When the first clamping pads 14 and the second clamping pads 18 are severely worn due to long-term friction with tire 13, the first clamping pads 14 and the second clamping pads 18 can be unscrewed and removed from the movable rod 15 and the hydraulic rod 17 for replacement. The above technical solution automatically adjusts the position of tire 13, making it precisely aligned with the installation position on the semi-trailer, thus reducing labor costs.
[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
