A first support roller 7 and a second support roller 1005 are rotatably mounted on the fixed support component 5 and the movable support component 10, respectively. The first support roller 7 and the second support roller 1005 cooperate with each other to support the tire.

[0032] like Figure 3 As shown, the base frame 1 includes two first crossbeams 101 and two first longitudinal beams 102. The two first crossbeams 101 and the two first longitudinal beams 102 are arranged in parallel and spaced apart to form a rectangular frame structure. A base plate 2 is fixedly connected to the bottom surface of the base frame 1. A roller 3 is fixedly connected to the bottom surface of the base plate 2 near the four vertices to facilitate the movement of the transfer device.

[0033] In this embodiment, the roller 3 has a built-in locking function. When the transfer device is moved to the designated position, the roller 3 is locked to improve the stability of the overall device. In addition to this embodiment, other locking structures can also be set on the base frame 1 to lock the transfer device when it is moved to the designated position, so as to prevent the overall device from shifting during tire loading and unloading and affecting the use effect.

[0034] As shown in Figure 4 The carrying frame 4 comprises two second transverse beams 401 arranged in parallel and spaced apart and two second longitudinal beams 402 arranged in parallel and spaced apart, which form a rectangular frame structure. Two reinforcing beams 403 are arranged between the two second longitudinal beams 402. The reinforcing beams 403 are arranged in parallel with the second longitudinal beams 402 and are fixedly connected to the second transverse beams 401 at both ends. A first vertical beam 404 is fixedly connected to each reinforcing beam 403 near one end at the top. A cross bar 405 is fixedly connected to the top end of the first vertical beam 404.

[0035] The fixed support assembly 5 comprises a first vertical plate 501 and a second vertical plate 502 arranged in parallel and spaced apart. The first vertical plate 501 and the second vertical plate 502 are fixedly connected to the upper surface of the carrying frame 4. A first shaft sleeve 503 is fixedly connected between the first vertical plate 501 and the second vertical plate 502. A first rotating shaft 6 is rotatably installed in the first shaft sleeve 503.

[0036] A first support roller 7 is fixedly installed on the first rotating shaft 6 between the two fixed support assemblies 5. The first support roller 7 is made of rubber. On the one hand, it forms a flexible contact with the tire to prevent damage to the tire. On the other hand, the rubber material has a large friction force, which can better support the tire and improve the safety of the device in use.

[0037] In this embodiment, the rotating connection mode of the first rotating shaft 6 and the first shaft sleeve 503 can be bearing connection or nylon shaft sleeve connection, which ensures that the first rotating shaft 6 can freely rotate in the first shaft sleeve 503, thereby driving the first support roller 7 to rotate.

[0038] The two first vertical plates 501 are located outside the two second vertical plates 502, and the distance between the two first vertical plates 501 is greater than the width of the tire to be transported. The upper surface of the first vertical plate 501 is slightly higher than the bottom surface of the tire, and the upper surface of the second vertical plate 502 is lower than the bottom surface of the tire. When the tire contacts the first support roller 7, the two first vertical plates 501 limit the displacement of the tire in the width direction, preventing the tire from shifting and falling off.

[0039] Two groups of hinge seats 8 arranged in parallel and spaced apart are fixedly connected to the upper surface of the carrying frame 4 corresponding to the movable support assembly 10. A second shaft sleeve 9 is fixedly connected between the two hinge seats 8 in the same group.

[0040] As shown in Figure 5As shown, the movable support assembly 10 comprises a second rotating shaft 1001, both ends of the second rotating shaft 1001 are rotatably installed in the second shaft sleeves 9 at both ends, the rotating connection mode of the second rotating shaft 1001 and the second shaft sleeve 9 can be bearing connection or nylon shaft sleeve connection, which ensures that the second rotating shaft 1001 can freely rotate in the second shaft sleeve 9, thereby driving the whole movable support assembly 10 to rotate.

[0041] Both ends of the second rotating shaft 1001 are fixedly installed with a second vertical beam 1002 at positions outside the hinge seat 8, the distance between the two second vertical beams 1002 is slightly greater than the width of the tire to be transported, which limits the displacement of the tire in the width direction, and cooperates with the two first vertical plates 501 to make the tire more reliably placed on the transfer device.

[0042] The second vertical beam 1002 is provided with a connecting beam 1003 at a position close to the top end, the connecting beam 1003 is U-shaped and the U-shaped gap faces the tire side, the two ends of the connecting beam 1003 are fixedly connected with the second vertical beams 1002 on both sides, which enhances the strength of the movable support assembly 10.

[0043] A support shaft 1004 is arranged above the second rotating shaft 1001, both ends of the support shaft 1004 are fixedly installed on the second vertical beams 1002 on both sides, and a second support roller 1005 is rotatably installed on the support shaft 1004 at a position between the two second vertical beams 1002, the material of the second support roller 1005 is the same as that of the first support roller 7, and both of them cooperate to support the tire.

[0044] In this embodiment, the connecting mode of the second support roller 1005 and the support shaft 1004 can be bearing connection or nylon shaft sleeve connection, which ensures that the second support roller 1005 can freely rotate on the support shaft 1004.

[0045] As shown, Figure 2 One end of the second rotating shaft 1001 is fixedly installed with a turnover gear 11, the turnover gear 11 is meshingly connected with a turnover rack 12, and the turnover rack 12 is fixedly installed on the upper surface of the bearing frame 4 at a position corresponding to the turnover rack 12. A sliding groove is formed in the upper surface of the sliding rail 13, and the turnover rack 12 is slidingly installed on the sliding rail 13.

[0046] One end of the turnover rack 12 is provided with a turnover driving mechanism 14, the mounting end of the turnover driving mechanism 14 is fixedly installed on the upper surface of the bearing frame 4, and the telescopic end is fixedly connected with one end of the turnover rack 12. The telescopic end of the turnover driving mechanism 14 is extended or retracted, which drives the turnover rack 12 to move horizontally on the sliding rail 13, thereby driving the turnover gear 11 to rotate, and the turnover gear 11 drives the movable support assembly 10 to rotate around the hinge seat 8 through the second rotating shaft 1001.

[0047] In the embodiment, the turnover driving mechanism 14 can be selected from an electric push rod, a pneumatic push rod or a hydraulic push rod, which is used to drive the movable support assembly 10 to rotate to a required position through the meshing transmission of the turnover rack 12 and the turnover gear 11, and the movable support assembly 10 can be kept at a required angle by using the self-locking function of the electric push rod, the pneumatic push rod or the hydraulic push rod, and the original state can be kept in case of sudden power cut, thereby improving the reliability of the whole device.

[0048] One end of the first rotating shaft 6 is fixedly connected with a first motor 15, and a motor seat 406 is arranged at a position corresponding to the first motor 15 on the first vertical beam 404, and the mounting end of the first motor 15 is fixedly installed on the motor seat 406. The first motor 15 outputs rotating power to drive the first rotating shaft 6 to rotate, and further drive the first supporting roller 7 to rotate.

[0049] As shown in Figure 3 The lifting adjusting assembly 16 is arranged between the base frame 1 and the bearing frame 4, the mounting end of the lifting adjusting assembly 16 is fixedly connected to the upper surface of the lower mounting plate, and the execution end is fixedly installed on the lower surface of the bearing frame 4. The execution end of the lifting adjusting assembly 16 drives the bearing frame 4 to move up and down, and adjusts the height position to adapt to different use environments.

[0050] In the embodiment, the lifting adjusting assembly 16 is an electric push rod, and in order to ensure the stability of the up and down movement of the bearing frame 4, an electric push rod is arranged at a position close to the vertex below each reinforcing beam 403. The extension end of the electric push rod is extended or retracted to drive the bearing frame 4 to move to a suitable height position, thereby facilitating the loading and unloading of the tire.

[0051] In the embodiment, the lifting adjusting assembly 16 can also be selected from a hydraulic lifting mechanism or a pneumatic lifting mechanism, and the extension end of the hydraulic cylinder or the pneumatic cylinder is used to drive the bearing frame 4 to move up and down.

[0052] The control device 17 is further arranged on the cross rod 405, and the control device 17 is signal connected with the turnover driving mechanism 14, the first motor 15 and the lifting adjusting assembly 16. In the embodiment, the control device 17 is a prior art, which comprises a built-in PLC controller and a plurality of external control buttons. The control program is pre-written in the PLC controller, and the workers control the start and stop and the action direction of the turnover driving mechanism 14, the first motor 15 and the lifting adjusting assembly 16 by pressing the control buttons.

[0053] The control device 17 is detachably arranged on the cross rod 405, and the workers can take down the control device 17 to operate away from the transfer device, which is convenient for observing whether the position of the tire is adjusted to the position, and improves the assembly precision.

[0054] The initial active support assembly 10 is perpendicular to the carrier 4, the telescopic end of the turnover driving mechanism 14 is in the extended state, the worker moves the transfer device to the tire storage position, the telescopic end of the turnover driving mechanism 14 is retracted, the meshing transmission of the turnover rack 12 and the turnover gear 11 drives the active support assembly 10 to turn over and open.

[0055] When the active support assembly 10 is turned over to the limit position, the connecting beam 1003 is in contact with the ground to form a support, so that an inclined channel is formed between the active support assembly 10 and the ground, which facilitates the movement of the tire to the carrier 4, and the second support roller 1005 is rotated during the movement of the tire, so that the sliding friction between the tire and the active support assembly 10 is converted into rolling friction, further reducing the workload of the worker.

[0056] When the tire is stored on a higher support, the distance that the telescopic end of the turnover driving mechanism 14 is extended can be controlled to control the angle at which the active support assembly 10 is turned over and opened, so that the active support assembly 10 can be connected to tire storage supports of different heights, improving the convenience of use of the device. By using the locking function of the turnover driving mechanism 14, the active support assembly 10 can be locked at a specified angle to prevent the active support assembly 10 from shaking and causing the tire to fall during tire loading and unloading.

[0057] Due to the action of gravity, after the tire is transferred to the carrier 4, the bottom surface is in contact with the two reinforcing beams 403 on the carrier 4 to form stable support for the tire. At this time, the turnover driving mechanism 14 is started in reverse to drive the turnover rack 12 to move in reverse, and then drive the active support assembly 10 to turn over and close.

[0058] The active support assembly 10 is turned over to the inside, so that the second support roller 1005 is in contact with the tire. At this time, the two reinforcing beams 403 and the second support roller 1005 form support for the tire. The active support assembly 10 continues to turn over to the inside, pushing the tire away from the reinforcing beams 403 and closer to the first support roller 7, so that the tire is finally supported by the first support roller 7 and the second support roller 1005.

[0059] After the tire is loaded, the transfer device is moved to the assembly station, the height of the tire is adjusted by starting the lifting adjustment assembly 16, so that the position of the tire corresponds to the position of the axle, then the first motor 15 is started to drive the first support roller 7 to rotate, and then drive the tire to rotate on the transfer device, so that the mounting hole on the hub is aligned with the mounting bolt on the axle, and the transfer device is further pushed to mount the tire on the axle.

[0060] In this embodiment, the turnover driving mechanism 14, the first motor 15 and the lifting adjustment assembly 16 are all prior art, and appropriate models can be selected for purchase and use according to actual use, which will not be described in detail in the utility model.

[0061] Embodiment 2: as shown in Figure 6 The difference between Embodiment 2 and Embodiment 1 is that, based on the above-mentioned tire assembly transfer device, a plurality of mounting holes are evenly arranged on the first vertical beam 404 in the up-down direction, and the support shaft 1004 is detachably mounted in one of the mounting holes.

[0062] When a tire with a larger diameter needs to be transported, the support shaft 1004 is moved to the lower mounting hole and fixedly mounted, and the movable support assembly 10 is turned inward to a larger angle, so that the tire is always in effective contact with the first support roller 7 and the second support roller 1005. Conversely, if a tire with a smaller diameter needs to be transported, the support shaft 1004 is moved to the upper mounting hole and fixedly mounted, and the turning angle of the movable support assembly 10 is adjusted, so that the tire is more stably transported.

[0063] In this way, the transfer device can be adapted to transport tires of different diameters, reducing the types of production workshop transfer devices and reducing manufacturing and storage costs.

[0064] For those skilled in the art, according to the teachings of the present application, changes, modifications, replacements and variations made to the embodiments without departing from the principles and spirits of the present application still fall within the scope of protection of the present application.
