Description

Technical Field

[0001] This utility model relates to the field of tire repair technology, and specifically discloses a tire disassembly and assembly device for large-scale vehicles. Background Technology

[0002] Vehicle (such as automobile) tires typically consist of an outer tire (containing an inner tube), a rim (also called a steel pot), and a retaining ring. Tire repair requires disassembling these components; this process is called tire removal. Currently, tire removal involves using a pry bar to slowly separate the tire from the retaining ring. This requires considerable force and time, making it particularly difficult and time-consuming. This is especially true when removing heavy-duty truck tires, which are larger and require even more force, making them difficult for workers to remove.

[0003] For example, utility model patent application number 2020231236929 discloses a tire disassembly machine, including a frame, a drive device, a positioning device, and a separation device. A rotating shaft is concentrically arranged on the output shaft of the drive device, and a support platform is provided on the top of the rotating shaft. A positioning device is provided on the support platform. The positioning device includes a first bidirectional screw, a second bidirectional screw, and a linkage mechanism. Both the first bidirectional screw and the second bidirectional screw pass through the support platform. The two ends of the first bidirectional screw are rotatably connected to the support platform, and the two ends of the second bidirectional screw are rotatably connected to the support platform. The first bidirectional screw and the second bidirectional screw are perpendicular to each other. Two first sliders are provided on the first bidirectional screw, and two second sliders are provided on the second bidirectional screw. A first sliding groove is provided on the support platform to allow the first sliders and the second sliders to slide. A linkage mechanism is provided on the first bidirectional screw and the second bidirectional screw to drive the first bidirectional screw and the second bidirectional screw to rotate. Existing tire removal machines require the tire to be laid horizontally on the machine before removal. Since heavy truck tires are heavy, it is difficult for workers to lift them and lay them horizontally on the machine. This step requires a lot of time and effort, thus reducing the efficiency of tire removal. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a tire removal and installation device for heavy trucks, so as to solve the technical problem that when removing tires from heavy trucks, workers need to spend a lot of time and physical strength to place the tires horizontally on the tire removal machine, which reduces the efficiency of tire removal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tire disassembly and assembly device for large vehicles, comprising a fixed frame, two sets of support columns fixedly connected to the fixed frame, a horizontal moving device fixedly connected to the fixed frame, and a movable platform mounted on the horizontal moving device; a tire flipping mechanism for flipping the tire is mounted on the movable platform; and a tire removal mechanism for disassembling the tire and rim is mounted on the fixed frame. In use, the tire flipping mechanism flips the tire, eliminating the need for manual flipping by workers, saving time and improving the efficiency of tire disassembly.

[0006] Furthermore, the tire flipping mechanism includes a movable plate, on which a movable rod is fixedly connected. The movable rod is slidably mounted on the moving platform, and a mating block is hinged to one end of the movable rod. Limiting blocks are fixedly connected to both ends of the mating block, and both sets of limiting blocks are slidably mounted within the moving platform. A tire clamping device is provided on the movable plate, and a tire is clamped on the tire clamping device. Two sets of first hydraulic rods are provided between the fixed frame and the movable plate, and the two sets of first hydraulic rods are respectively hinged to the fixed frame and the movable plate at both ends. The tire flipping mechanism can automatically flip the tire, thereby cooperating with the tire removal mechanism to separate the tire from the rim. Moreover, when flipping the tire, no manual flipping is required from the operator, and the tire can be flipped to a horizontal position, saving the operator's physical strength and improving the efficiency of tire flipping.

[0007] Furthermore, two sets of auxiliary flipping mechanisms are provided between the movable plate and the moving platform; each auxiliary flipping mechanism includes a sliding frame, on which a first connecting rod and a second connecting rod are fixedly connected; a mating column is fixedly connected to the movable plate, and the mating column is slidably engaged with the sliding frame; the first connecting rod is fixedly connected to the moving platform, and the second connecting rod is slidably engaged with the fixed frame. The auxiliary flipping mechanisms are used to limit the movement of the movable plate, ensuring that it can only move along a fixed trajectory, thereby preventing the tire from failing to flip properly during rotation.

[0008] Furthermore, the tire removal mechanism includes a second hydraulic rod, which is fixedly connected to a fixed frame. A connecting block is mounted on the second hydraulic rod, and a mating frame and a pressure block are fixedly connected to the connecting block. A rotatable roller is mounted on the mating frame. The tire removal mechanism is used to separate the tire from the rim. During disassembly, the rollers reduce damage to the tire caused by the tire removal mechanism, preventing damage to the tire due to external forces and reducing its service life.

[0009] Furthermore, the pressure block consists of two sets of inclined rectangular blocks with different inclination angles, and the pressure block is used to separate the tire from the rim.

[0010] The working principle and beneficial effects of this solution are as follows:

[0011] When in use, the staff first aligns the tire with the tire clamping device, then fixes the tire with the tire clamping device, then activates the first hydraulic rod, and flips the tire to a horizontal position through the tire flipping mechanism. Then, the tire is moved to the designated position through the horizontal moving device, and the tire is separated from the rim through the tire removal mechanism. At the same time, it can prevent damage to the tire when removing the tire, and make it convenient for the staff to remove the tire.

[0012] When the tire flipping mechanism is running, the first hydraulic rod drives the movable plate to slide in the arc-shaped groove, which in turn drives the limiting block to slide in the limiting groove. This causes one end of the movable rod and the mating block to move downward in the arc-shaped groove, thereby completing the purpose of flipping the movable plate. When the movable plate is flipping, it will not have too much fluctuation, thus ensuring that it will not conflict with the fixed frame and making it convenient for workers to disassemble the tire, improving the efficiency of tire disassembly.

The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0020] The following detailed description illustrates the specific implementation method:

[0021] Example

[0022] like Figures 1 to 5 As shown, a tire removal and installation device for a yard crane truck is disclosed.

[0023] It includes a fixed frame 1, on which a support column 2 is provided. The support column 2 is used to support the fixed frame 1 and ensure that it does not affect the tire disassembly work. The fixed frame 1 is provided with a horizontal moving device 3, on which a moving platform 4 is provided. The horizontal moving device 3 can drive the moving platform 4 to move horizontally.

[0024] The movable platform 4 is equipped with a tire flipping mechanism, which includes a movable plate 6. The movable plate 6 is equipped with a tire clamping device 7 and a movable rod 5. The movable rod 5 and the tire clamping device 7 are located on two end faces of the movable plate 6, respectively. The tire clamping device 7 is used to clamp the tire. The movable platform 4 has an arc-shaped groove 14. The arc-shaped groove 14 is a right-angled triangle with an arc-shaped hypotenuse. The arc opening faces away from the right angle. The movable rod 5 is slidably locked in the arc-shaped groove 14. One end of the movable rod 5 is hinged to a mating block 15. Both ends of the mating block 15 are provided with limit blocks 16. Limit grooves 17 are opened on both inner walls of the arc-shaped groove 14. The limit grooves 17 are vertical. The two sets of mating blocks 15 and the two sets of limit blocks 16 are slidably locked in the two sets of limit grooves 17, respectively. Two sets of first hydraulic rods 8 are provided between the fixed frame 1 and the movable plate 6. The fixed end of the first hydraulic rod 8 is hinged to the fixed frame 1, and the telescopic end is hinged to the movable plate 6.

[0025] Two sets of auxiliary flipping mechanisms are provided between the movable plate 6 and the moving platform 4. The two sets of auxiliary flipping mechanisms are located on both sides of the moving platform 4. The auxiliary flipping mechanism includes a sliding frame 10. A first connecting rod 11 and a second connecting rod 12 are fixedly connected to the sliding frame 10. The first connecting rod 11 is fixedly connected to the moving platform 4. A sliding groove 13 is provided on the fixed frame 1. The second connecting rod 12 is slidably locked in the sliding groove 13. A mating post 9 is provided on the movable plate 6. The mating post 9 is slidably locked in the sliding frame 10.

[0026] A tire-removing mechanism is provided on the fixed frame 1. The tire-removing mechanism includes a second hydraulic rod 18. The fixed end of the second hydraulic rod 18 is fixedly connected to the fixed frame 1. A connecting block 19 is provided on the telescopic end of the second hydraulic rod 18. A mating frame 21 is fixedly connected to the connecting block 19. A rotatable roller 22 is provided on the mating frame 21. Both the mating frame 21 and the roller 22 are located at the bottom end of the connecting block 19. A pressure block 20 is fixedly connected to the connecting block 19. The pressure block 20 is located on one side of the connecting block 19. The pressure block 20 consists of two sets of inclined rectangular blocks. One set of rectangular blocks that contacts the connecting block 19 has a larger inclination angle, while the other set of rectangular blocks has a smaller inclination angle. The pressure block 20 is used to extend into the tire, thereby ensuring that the outer tire can be separated from the rim.

[0027] In practice

[0028] In use, the operator first rolls the tire to be removed until it aligns with the tire clamping device 7, at which point the tire is placed vertically. The operator then secures the tire using the tire clamping device 7. Next, the operator activates the first hydraulic rod 8, causing its telescopic end to retract. This retracts the first hydraulic rod 8, which, through the tire flipping mechanism, rotates the movable plate 6 around the moving platform 4, ensuring that both the movable plate 6 and the tire are placed horizontally on the moving platform 4. The operator then activates the horizontal moving device 3, which moves the moving platform 4, which in turn moves the movable plate 6 and the tire until the tire reaches the designated position. At this point, the cooperating column 9 drives the sliding frame 10 and the second... The connecting rod 12 slides on the sliding groove 13. At this time, the gap between the tire and the rim is aligned with the pressure block 20. Then, the operator activates the second hydraulic rod 18. The telescopic end of the second hydraulic rod 18 extends, driving the connecting block 19, the pressure block 20, and the roller 22 to move downward until the pressure block 20 presses down on the tire, causing the tire to disengage from the rim. At this time, the roller 22 contacts the tire. Then, the tire clamping device 7 rotates, causing the tire to rotate and engage with the rim. At the same time, the roller 22 rolls on the tire and rotates on the mounting bracket 21, which can prevent the tire removal mechanism from damaging the tire when removing the tire.

[0029] When the tire flipping mechanism is running, the first hydraulic rod 8 drives the movable plate 6 to move, and the movable plate 6 drives the movable rod 5 to slide in the arc groove 14. When the movable plate 6 slides, the movable rod 5 rotates around the mating block 15, and at the same time drives the limiting block 16 to slide in the limiting groove 17 through the mating block 15, so that one end of the movable rod 5 and the mating block 15 move downward in the arc groove 14, while the other end of the movable rod 5 always moves on the top surface of the moving table 4, thereby completing the purpose of flipping the movable plate 6. When the movable plate 6 is flipping, the mating column 9 slides on the sliding frame 10, thereby limiting the movable plate 6.

[0030] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
