Description
Technical Field
[0001] This utility model relates to the technical field of tire disassembly and assembly equipment, specifically, to a tire disassembly and assembly device. Background Technology
[0002] Tires are one of the most important components of various land vehicles. They directly bear the weight of the vehicle and provide the friction needed for movement through contact with the ground. Given their working environment, tires are also one of the main consumables for automobiles. The rims supporting the tires are generally made of metal, possessing high strength, durability, and a longer lifespan than the tires themselves. This makes tire replacement a frequent part of routine maintenance for automobiles. Considering the current number of land vehicles in operation, tire replacement is a very heavy and time-consuming task. Existing technologies offer various tire changers or tire-changing machines to assist workers in improving tire-changing efficiency and reducing manual labor intensity.
[0003] There are two common types of tires: regular tires, which include an inner tube and an outer tube, and tubeless tires, also known as tubeless tires. Tubeless tires have the tire carcass in direct contact with the rim, providing good heat dissipation. The surface of a tubeless tire is made of high-quality rubber, which increases surface tension after inflation, creating pressure on the inner surface and improving its self-sealing ability against punctures. Once punctured, unlike regular tires where all the air leaks out instantly, the air will continue to leak for a certain period of time, ensuring safety during high-speed driving.
[0004] Tubeless tire sealing relies on the outer edge of the tire fitting tightly against the inner edge of the rim, using the air pressure inside the tire to create a close seal. The tire bead is the part that contacts the rim, containing a high-strength triangular rubber and steel wire ring structure. After the tire pressure inflates the tire, the bead adheres tightly to the rim, preventing air pressure from leaking through gaps and firmly securing the tire to the rim. Since the sealing performance of a tire, especially a tubeless tire, is closely related to the bead's fit, damage to the bead will severely affect the tire's sealing performance.
[0005] In tire repair work, the step of separating the tire bead from the rim is called tire loosening. In existing technology, the tire is usually rotated first, and then a tire pressure wheel is used to press the tire so that there is a certain gap between the edge of the tire sidewall and the edge of the rim. Then, a pry bar is used manually to forcefully impact the joint between the tire bead and the rim to loosen the tire, or a separation shovel is used alone to impact and separate them, which is time-consuming and laborious.

[0027] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.
[0028] like Figures 1-2 As shown, this embodiment provides a tire mounting and dismounting device, which includes a rotary table 100 that can be driven by a motor to rotate circumferentially. The rotary table 100 is used to support the tire and drive the tire to rotate circumferentially. It also includes a first pressure roller 200 and a second pressure roller 300. When the tire is placed on the rotary table 100, the first pressure roller 200 and the second pressure roller 300 can be positioned on the upper and lower sides of the tire, respectively. Specifically, the first pressure roller 200 is positioned on the upper side of the tire, and the second pressure roller 300 is positioned on the lower side of the tire. The first pressure roller 200 and the second pressure roller 300 can apply pressure to the tire carcass on the upper and lower sides of the tire, respectively, so that the corresponding position of the tire carcass can be separated from the tire rim. It also includes a tire hooker 400. Taking the first pressure wheel 200 as an example, when the first pressure wheel 200 applies pressure to the tire body, causing part of the tire body to separate from the rim, the tire hooker 400 can lift the part of the tire body that is separated from the rim, thereby keeping the tire body and the rim in a separated state. Furthermore, in conjunction with the rotating table 100 driving the tire to rotate, and the first pressure wheel 200 continuously separating the tire body from the rim during the tire rotation, it can better achieve the separation of the entire tire body from the rim and better complete the tire removal operation.
[0029] In some embodiments, the tire mounting and dismounting equipment of this embodiment further includes a mounting base 10, wherein the rotary table 100, the first tire pressure roller 200, the second tire pressure roller 300 and the tire hook 400 are all mounted on the mounting base 10, so that multiple parts are integrated into a single structure, which facilitates the transportation and use of the tire mounting and dismounting equipment.
[0030] Furthermore, the tire hook 400 can be mounted on the mounting base 10 via a drive motor 410, a telescopic rod 420, and other mechanisms, so that when the tire is on the turntable 100, the tire hook 400 can move along the axial and radial directions of the tire to better lift the part of the tire body that is separated from the rim.
[0031] In some embodiments, a guide rail assembly is provided on the mounting base 10, wherein the first pressure roller 200 and the second pressure roller 300 are both disposed on the guide rail assembly. When the tire is on the rotary table 100, the first pressure roller 200 and the second pressure roller 300 can reciprocate along the axial direction of the tire under the drive of the guide rail assembly, so as to adjust the position of the first pressure roller 200 and the second pressure roller 300, facilitating the pressing of the first pressure roller 200 and the second pressure roller 300 onto the tire body.
[0032] Furthermore, the guide rail assembly includes a bracket 510, a guide rail post 520, a drive cylinder 530, and a guide wheel 540. The guide wheel 540 and the drive cylinder 530 are both mounted on the bracket 510, and the bracket 510 cooperates with the guide rail post 520 through the guide wheel 540. When it is necessary to adjust the height position of the first pressure roller 200 and the second pressure roller 300, the drive cylinder 530 is activated, and the drive cylinder 530 can drive the bracket 510 to move on the guide rail post 520 through the guide wheel 540.
[0033] In some embodiments, the guide rail assembly further includes a first connecting plate 511 and a second connecting plate 512 disposed on the bracket 510, wherein the second connecting plate 512 is closer to the rotary table 100 than the first connecting plate 511, and the first pressure roller 200 is hinged to the first connecting plate 511 via the first rotating rod 210, so that the first pressure roller 200 can rotate relative to the guide rail assembly, allowing the operator to operate the first pressure roller 200 to rotate closer to or away from the rotary table 100.
[0034] Furthermore, a first locking interface 512a is provided on the second connecting plate 512. The first rotating rod 210 can be moved into the first locking interface 512a by rotation to limit the first rotating rod 210, thereby limiting the first tire pressure wheel 200, so that the first tire pressure wheel 200 can maintain a stable position and thus stably press the tire body.
[0035] In some embodiments, the guide rail assembly further includes a third connecting plate 513 and a fourth connecting plate 514 disposed on the bracket 510, wherein the fourth connecting plate 514 is closer to the rotary table 100 than the third connecting plate 513, and the second pressure roller 300 is hinged to the third connecting plate 513 via the second rotating rod 310, so that the second pressure roller 300 can rotate relative to the guide rail assembly, allowing the operator to operate the second pressure roller 300 to rotate closer to or away from the rotary table 100.
[0036] Furthermore, a second locking interface 514a is provided on the fourth connecting plate 514. The second rotating rod 310 can be moved into the second locking interface 514a by rotation to limit the second rotating rod 310, thereby limiting the second tire pressure wheel 300, so that the second tire pressure wheel 300 can maintain a stable position and thus stably press the tire body.
[0037] In some embodiments, a first slot 512b is provided on the first connecting plate 511 or the second connecting plate 512. In this embodiment, the first slot 512b is provided on the second connecting plate 512, and a first locking block 211 is rotatably provided on the first rotating rod 210. When the first rotating rod 210 is moved into the first locking interface 512a by rotating it in the left and right directions, the first rotating rod 210 is initially limited. However, when a large pulling force is applied from the outside, the first rotating rod 210 will still move out of the first locking interface 512a. In this embodiment, after the first rotating rod 210 is moved into the first locking interface 512a, the first locking block 211 is rotated in the up and down directions, so that the first locking block 211 moves into the first slot 512b, thereby enabling a secondary limitation of the first rotating rod 210. This can better improve the limiting effect of the first rotating rod 210, so that the first tire pressure roller 200 can stably press the tire body.
[0038] In some embodiments, a second slot 514b is provided on the third connecting plate 513 or the fourth connecting plate 514. In this embodiment, the second slot 514b is provided on the fourth connecting plate 514, and a second locking block 311 is rotatably provided on the second rotating rod 310. When the second rotating rod 310 is moved into the second locking interface 514a by rotating it in the left and right directions, the second rotating rod 310 is initially limited. However, when a large pulling force is applied externally, the second rotating rod 310 will still move out of the second locking interface 514a. In this embodiment, after the second rotating rod 310 is moved into the second locking interface 514a, the second locking block 311 is rotated in the up and down directions, so that the second locking block 311 moves into the second slot 514b, thereby enabling a secondary limitation of the second rotating rod 310. This can better improve the limiting effect of the second rotating rod 310, so that the second tire pressure roller 300 can stably press the tire body.
[0039] In some embodiments, an auxiliary manipulator 600 is also provided on the mounting base 10. After the first tire pressure roller 200 or the second tire pressure roller 300 separates part of the tire body from the rim, the auxiliary manipulator 600 can cooperate to press the tire body to maintain the stability of the tire body and the rim in a separated state, so as to facilitate the separation of the entire tire body from the rim.
[0040] In some embodiments, the auxiliary manipulator 600 includes a first connecting rod 610 and a second connecting rod 620 that are rotatably connected together. The end of the first connecting rod 610 away from the second connecting rod 620 is rotatably connected to the mounting base 10, and a pressure block 640 is connected to the end of the second connecting rod 620 away from the first connecting rod 610 via an electric telescopic rod 630.
[0041] When the first pressure roller 200 presses down on the tire body to separate part of the tire body from the rim, the operator can move the pressure block 640 above the tire body by rotating the first connecting rod 610 and the second connecting rod 620, and then drive the pressure block 640 to press down on the tire body by the electric telescopic rod 630, thereby realizing the auxiliary pressing of the tire body by the auxiliary robot 600, which facilitates the separation of the entire tire body from the rim.
[0042] In some embodiments, a lifting cylinder 700 and a placement frame 710 are provided on one side of the bottom of the mounting base 10. The placement frame 710 is connected to the output shaft of the lifting cylinder 700. When the tire is placed on the placement frame 710, the lifting cylinder 700 is activated. The lifting cylinder 700 can drive the placement frame 710 to raise the tire to the same height as the rotary table 100, thereby facilitating the movement of the tire onto the rotary table 100 or the removal of the tire from the rotary table 100.
[0043] Furthermore, multiple rollers 711 are provided on the placement rack 710, so that the staff only needs to push the tire to move it on the placement rack 710; when the lifting cylinder 700 drives the placement rack 710 to raise the tire to the same height as the rotating table 100, the staff can push the tire, and with the action of the rollers 711, the tire can be moved to the rotating table 100 in a better way, achieving the effect of saving time and effort.
[0044] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
