Description

Technical Field

[0001] The present invention relates to the field of tire disassembly and assembly, and specifically to a vehicle-mounted tire changer assembly. Background Art

[0002] With the continuous growth of the number of automobiles, vehicle-mounted tire changers are increasingly widely used in scenarios such as mobile tire repair and field rescue. Currently, when performing tire disassembly operations, vehicle-mounted tire changers generally adopt an operation mode in which workers manually push the tire close to the tire disassembly shovel and cooperate with the cylinder to drive the tire disassembly shovel to move, to initially separate the bead on the tire from the wheel hub.

[0003] In this process, the worker not only needs to manually maintain the precise alignment of the connection between the bead and the wheel hub with the tire disassembly shovel throughout the process, but also needs to ensure the stability of the tire. And during the initial separation process, after the initial separation of one position of each pair of bead and wheel hub, the position of the tire needs to be changed to perform the initial separation operation of the next position of the bead and the wheel hub. Therefore, this process requires the worker to move the tire multiple times and still need to align it with the tire disassembly shovel after the movement, to prevent the tire disassembly shovel from contacting the wheel hub when moving and causing scratches on the edge of the wheel hub, and resulting in a low initial separation efficiency of the bead and the wheel hub; in addition, due to the heavy weight of the tire, it is rather laborious for the worker to change the position of the tire multiple times, greatly increasing the labor intensity of the worker.

[0019] Compared with the prior art, a vehicle-mounted tire changer assembly provided by an embodiment of the present invention has the following beneficial effects:

[0020] 1. When the bead on the tire and the wheel hub are initially separated in the present invention, the tire can be stably positioned on the support frame through the stabilizing mechanism. Then, by rotating the turntable, the connection position between the bead and the wheel hub can be aligned with the tire removal shovel. When performing the initial separation, only a single flip and multiple rotations of the tire are required, avoiding the cumbersome operations of manually repeatedly adjusting the position and angle of the tire, improving the initial separation efficiency, greatly reducing the labor intensity of the staff, and automatically applying lubricating oil to the contact position between the bead and the wheel hub during the rotation of the tire, improving the protection of the bead and the wheel hub when they are separated.

[0021] 2. In the present invention, a rotating roller, a positioning component, and a support plate are provided.

Detailed implementation manners

[0035] The following will Figure 1 - Figure 11 make a further detailed description of this application.

[0036] Please refer to Figure 1 , a vehicle-mounted tire changer assembly, including a base 1 and a connecting plate 2 fixedly arranged at the rear side of the base 1 and connected to an external vehicle-mounted mobile frame. A separating mechanism 3 for preliminarily separating the bead of a tire from a wheel hub is arranged on the right side of the base 1. A tire peeling mechanism 4 for thoroughly separating the bead of a tire from a wheel hub is arranged on the upper part of the base 1. A fixing frame 5 is fixedly arranged on the right side of the base 1, and a stabilizing mechanism 6 for stabilizing the tire during tire peeling is arranged inside the fixing frame 5.

[0037] Refer to Figure 2 and Figure 6 , the stabilizing mechanism 6 includes a supporting frame 61 slidably arranged inside the fixing frame 5. A plurality of rotating rollers 62 are rotatably arranged inside the supporting frame 61. Two cross bars 63 are fixedly arranged between the last two rotating rollers 62 inside the supporting frame 61. A positioning assembly 64 for positioning the tire is arranged on the two cross bars 63 together. The positioning assembly 64 includes two positioning plates 641 symmetrically arranged left and right on the two cross bars 63, and a moving plate 642 is arranged on the upper part of the positioning plate 641.

[0038] Refer to Figure 6, the positioning plate 641 on the right side is fixedly arranged on the two cross bars 63, and the positioning plate 641 on the left side is slidably arranged on the two cross bars 63. A return spring 644 is sleeved on the outer side of the cross bar 63, and the two ends of the return spring 644 are respectively connected with the corresponding positioning plate 641 and the support frame 61. Rubber pads I are arranged on the sides of the two positioning plates 641 close to each other, and the front sides of the positioning plate 641 and the moving plate 642 are in a slope shape.

[0039] When separating the bead on the tire from the wheel hub, the staff can place the tire to be disassembled on the rotating roller 62 on the support frame 61, and then roll the tire to a position close to the separating mechanism 3. At this time, the tire will be located between the two rotating rollers 62 at the rearmost side (as Figure 10 shown). The two rotating rollers 62 at the rearmost side can be used to initially position the tire. And during the process of the tire moving between the two rotating rollers 62 at the rearmost side, the tire will contact and squeeze the two positioning plates 641 and the two moving plates 642. At this time, the elastic force of the return spring 644 can make the tire located between the two positioning plates 641 and the two moving plates 642, so that the tire can be firmly clamped by the two positioning plates 641 and the moving plates 642, and the normal rotation of the tire will not be affected.

[0040] Refer to Figure 6 , a threaded rod 8 is arranged at the rear side of the fixed frame 5, the front end of the threaded rod 8 is rotatably connected with the rear side of the support frame 61, and a turntable 9 is fixedly arranged at the rear end of the threaded rod 8.

[0041] Refer to Figure 1 and Figure 8 , chutes 10 are respectively arranged at the left and right ends inside the fixed frame 5, and a plurality of sliders 11 which are located in the chutes 10 and slidably connected with the chutes 10 are fixedly arranged on the left and right sides of the support frame 61. The front side of the support frame 61 is in an inclined shape, and the bottom of the front side of the support frame 61 and the bottom of the fixed frame 5 are at the same horizontal height as the bottom of the base 1.

[0042] Refer to Figure 3 , the separating mechanism 3 includes a cylinder 31 fixedly arranged inside the base 1, the output end of the cylinder 31 penetrates out of the inside of the base 1 and a rotating ring 32 is rotatably arranged on its outer side. A tire removing shovel 33 is fixedly arranged on the right side of the rotating ring 32, a push rod 34 for driving the rotating ring 32 to rotate is fixedly arranged on the upper part of the outer side of the rotating ring 32, and a limiting rod 35 which contacts with the tire removing shovel 33 and is used for limiting the tire removing shovel 33 is fixedly arranged on the right side of the base 1.

[0043] After positioning the tire, the staff can rotate the turntable 9 to drive the threaded rod 8 to rotate. The rotation of the threaded rod 8 can drive the support frame 61 to move inside the fixed frame 5 through the cooperation of the slider 11 and the chute 10, thereby driving the tire to move, so that the connection position between the bead and the hub on the tire is aligned with the tire removal shovel 33. Then the staff holds the push rod 34 to drive the tire removal shovel 33 to rotate and adjust the use angle of the tire removal shovel 33. Then the air cylinder 31 works to drive the tire removal shovel 33 to move to initially separate the bead and the hub. Then the staff rotates the tire so that the tire rotates between the two rear rotating rollers 62, so that the tire removal shovel 33 can initially separate multiple positions on the same side of the bead and the hub. After initially separating multiple positions on the same side of the bead and the hub, the tire can be removed from between the two positioning plates 641. Then the tire is rotated 180 degrees on the rotating roller 62. Then the tire is continuously moved between the two positioning plates 641. Then the tire removal shovel 33 is used to continue separating the other side of the bead and the hub on the tire. Compared with the current situation where the tire needs to be moved multiple times and the connection position between the bead and the hub still needs to be aligned with the tire removal shovel 33 after the movement, it is more convenient and labor-saving, not only improving the initial separation efficiency of the bead and the hub, but also reducing the labor intensity of the staff.

[0044] And by rotating the turntable 9, the use position of the support frame 61 can be adjusted, so that the connection position between the bead and the hub on different-sized tires can be aligned with the tire removal shovel 33, facilitating the initial separation of different-sized beads and hubs.

[0045] Refer to Figure 1 As shown in the figure, a support plate 15 is fixedly arranged on the upper right side of the fixed frame 5, and a second rubber pad is fixedly arranged on the side of the support plate 15 close to the base 1.

[0046] In order to further improve the stability during the initial separation of the bead and the hub, after the tire is positioned between the two positioning plates 641, when the tire removal shovel 33 moves to initially separate the bead and the hub, a rightward thrust will be generated on the tire. At this time, the support plate 15 can be used to stably support the tire, further ensuring the stability of the tire when the bead and the hub are separated.

[0047] Refer to Figure 6 and Figure 7 As shown in the figure and another figure, a groove is formed inside the moving plate 642, and a brush 643 for applying lubricating oil to the outer side of the bead is fixedly arranged in the groove. A slot is formed in the upper part of the positioning plate 641. A plug 645 inserted into the slot is fixedly arranged at the bottom of the moving plate 642, and the plug 645 and the positioning plate 641 are locked by bolt four.

[0048] Refer to Figure 1 and Figure 2, an oil supply assembly 7 for supplying lubricating oil to the brush 643 is provided on the upper part of the base 1. The oil supply assembly 7 includes an oil storage cylinder 71 fixedly arranged at the rear side of the upper part of the base 1. A fuel pump 72 is fixedly arranged at the rear side of the upper part of the base 1. An oil suction pipe 73 is connected to the input end of the fuel pump 72. One end of the oil suction pipe 73 far from the fuel pump 72 is communicated with the oil storage cylinder 71. A sealing cover 74 is screwed on the upper part of the oil storage cylinder 71 through threads. An oil outlet pipe 75 is connected to the output end of the fuel pump 72.

[0049] Refer to Figure 2 and Figure 9 , an oil storage cavity 12 is formed inside the moving plate 642. A guide oil pipe 13 is commonly connected between the two oil storage cavities 12. Two valves symmetrically arranged left and right are fixedly arranged on the guide oil pipe. One end of the oil outlet pipe 75 far from the fuel pump 72 is communicated with the guide oil pipe 13. A plurality of oil outlet holes 14 communicating with the oil storage cavity 12 and the groove are formed inside the moving plate 642. Both the oil outlet pipe 75 and the guide oil pipe 13 are flexible hoses.

[0050] When positioning the tire between the two positioning plates 641 and the two moving plates 642, then the staff can adjust the use position of the moving plate 642 by screwing the bolt four, so that the brush 643 on the moving plate 642 is located at the connection position between the bead and the wheel hub. Then, before initially separating multiple positions of the bead and the wheel hub, the fuel pump 72 works. The fuel pump 72 works to extract the lubricating oil inside the oil storage cylinder 71 through the oil suction pipe 73. Then, the lubricating oil sequentially enters the inside of the oil storage cavity 12 through the oil outlet pipe 75 and the guide oil pipe 13. Then, the lubricating oil in the oil storage cavity 12 drips onto the brush 643 through the oil outlet holes 14. During the oil supply process, the amount of lubricating oil dripping onto the brush 643 can be reasonably controlled according to the situation through the valve, which can effectively avoid waste of lubricating oil. At this time, the staff can rotate the tire, so that the lubricating oil can be smeared on the outer side of the bead, making it unnecessary to manually smear lubricating oil during the subsequent initial separation and complete separation of the bead and the wheel hub, and further improving the protection of the bead and the wheel hub compared to not smearing lubricating oil during the initial separation of the bead and the wheel hub at present.

[0051] Refer to Figure 2 , Figure 4 and Figure 5 , the tire removing mechanism 4 includes a placing seat 41 fixedly arranged on the upper part of the base 1. A supporting ring 42 driven by a rotating cylinder is rotatably arranged on the upper part of the placing seat 41. A fastening ring 43 for fastening the wheel hub is threadedly arranged on the outer side of the supporting ring 42. A positioning rod 44 is fixedly arranged on the upper part of the placing seat 41. The positioning rod 44 is located inside the supporting ring 42 and a tire removing assembly 45 is arranged on the positioning rod 44.

[0052] Refer to Figure 4, the tire demounting assembly 45 includes a sleeve 451 arranged at the upper end outside the positioning rod 44. The sleeve 451 consists of a round cover buckled on the positioning rod 44 and a cylinder fixedly arranged at the upper end of the round cover. The round cover is locked on the positioning rod 44 by a first bolt. A first connecting rod 452 is slidably arranged on the left side of the sleeve 451. The first connecting rod 452 and the sleeve 451 are locked by a second bolt. A connecting ring 453 is fixedly arranged on the side of the first connecting rod 452 away from the sleeve 451. A second connecting rod 454 is slidably arranged inside the connecting ring 453. The second connecting rod 454 and the connecting ring 453 are locked by a third bolt. A tire demounting head 455 is fixedly arranged at the bottom end of the second connecting rod 454.

[0053] After the bead and the wheel hub are initially separated, the staff can remove the sleeve 451 from the positioning rod 44, then remove the fastening ring 43 from the supporting ring 42. Then the staff aligns the wheel hub on the tire with the supporting ring 42 and places it. Then install the fastening ring 43 on the supporting ring 42, and then rotate the fastening ring 43 so that its bottom abuts against the wheel hub, so that the tire can be fastened on the supporting ring 42 (as Figure 11 shown). Then the staff installs the sleeve 451 on the positioning rod 44 by using the first bolt. Then adjust the using position of the tire demounting head 455 through the second bolt and the third bolt. Then the staff can insert a crowbar into the gap between the bead and the wheel hub, and then pry the crowbar so that the lifted part of the upper bead is sleeved on the tire demounting head 455. Then the rotating cylinder drives the supporting ring 42 to rotate, and the rotation of the supporting ring 42 drives the tire to rotate, so that the upper part of the bead and the wheel hub can be separated. Then lift the bead and use the same method to make the lifted part of the lower bead sleeved on the tire demounting head 455, and then continue to rotate the supporting ring 42 to completely separate the bead and the wheel hub.

[0054] During specific operation, when separating the bead and the wheel hub on the tire, after placing the tire on the support frame 61, the two rearmost rotating rollers 62 and the two positioning plates 641 can be used to clamp and stabilize the tire. Then rotate the tire, and through the cooperation of the oil supply assembly 7 and the brush 643, lubricating oil can be applied to the bead, so that it is not necessary to manually apply lubricating oil during the subsequent initial separation and complete separation of the bead and the wheel hub.

[0055] Then, the push rod 34 is toggled to adjust the use angle of the tire removal shovel 33. Next, the air cylinder 31 operates to drive the tire removal shovel 33 to move, preliminarily separating the tire bead and the wheel hub. Then, the staff can directly rotate the tire, so that the tire removal shovel 33 can be used to preliminarily separate multiple positions on the same side of the tire bead and the wheel hub. Then, the tire is rotated 180 degrees to continue the separation on the other side. Compared with the current situation where the tire needs to be moved multiple times, and after the movement, the connection position between the tire bead and the wheel hub still needs to be aligned with the tire removal shovel 33, it is more convenient and labor-saving. It not only improves the efficiency of the preliminary separation of the tire bead and the wheel hub, but also reduces the labor intensity of the staff.

[0056] Next, the fastening ring 43 is used to fasten the tire on the supporting ring 42. Then, the supporting ring 42 rotates and cooperates with the tire removing assembly 45 to completely separate the tire bead and the wheel hub.
