Description

Technical Field

[0001] The invention relates to the technical field of automobile maintenance equipment, in particular to a horizontal tire dismantling machine suitable for dismantling and mounting large tires. Background Art

[0002] Large motor vehicle tires are larger in diameter, making them more difficult to remove and install, typically requiring a larger tire changer. Conventional small vertical tire changers place the tire flat on the machine. Placing a large-diameter tire flat requires a significantly larger workbench diameter, creating a significant distance between the tire changer head and the clamping components, resulting in a significantly larger machine. This structure and tire clamping method are unsuitable for removing and installing large tires.

[0003] In order to meet the needs of disassembling and installing large tires, horizontal tire disassembling machines are generally used to disassemble and install large-diameter tires. On August 14, 2020, the applicant disclosed a large-scale horizontal tire disassembling machine with patent authorization announcement number CN111775640B that can prevent inner tube damage. The disassembling machine is provided with a clamping disc device for fixing the tire at the end of the cantilevered supporting movable arm. This cantilevered horizontal tire disassembling machine is convenient for clamping tires and has a relatively compact overall structure. However, for some extra-large tires, especially tires of some large engineering vehicles, a longer supporting movable arm is required. A supporting movable arm that is too long can easily cause vibration during the tire disassembly process of the tire disassembly machine. At the same time, the supporting movable arm also has the risk of deformation and bending. Moreover, the tire diameter range that can be disassembled and installed by this tire disassembly machine is also greatly limited.

[0004] Furthermore, due to the large diameter and weight of large tires, the greater rigidity of the tire bead, and the varying rim structures and materials, different tire removal components are required. The currently used single tire removal arm is incapable of quickly and smoothly removing and installing tires. Furthermore, the clamping process for large-diameter tires can also present challenges such as difficulty in straightening the tire. Summary of the Invention

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] See also Figure 1-7 As shown, an embodiment of the present invention provides a large-scale horizontal tire dismantling machine with variable position, which includes a base 4, and the pillow block 35 of the beam slide 3 is rotatably fixed on the bearing seats on both sides of the base 4 through a bearing assembly 34, and a power distribution and hydraulic pump station 7 is arranged near the base 4.

[0027] In this embodiment, the tire clamping component 1 is disposed on the crossbeam slideway. The variable tire clamping component 1 includes a cantilever beam 11 and a cantilever beam sleeve 12. A tire chuck is fixedly mounted at the front end of the cantilever beam sleeve 12. The cantilever beam 11 slides within the cantilever beam sleeve 12, forming a kinematic pair capable of axial relative motion. One end of a first drive component 13 is connected to the cantilever beam sleeve 12 and the other end is connected to a synchronous rotation connection component 18 to drive the cantilever beam sleeve 12. The cantilever beam 11 and the cantilever beam sleeve 12 preferably have a square cross-sectional shape. A shift shaft 111 is provided on the side of the cantilever beam 11 opposite the cross-moving connection component 16. The shift shaft 111 may be a cylinder located in the middle of the cantilever beam 11. The cantilever beam sleeve 12 is provided with a slide groove 121 on the same side as the cantilever beam 11. The slide groove 121 is an elongated, through-hole extending along the length of the cantilever beam sleeve 12, within which the shift shaft 111 slides. A support slide post 15 is fixed to the base 4. A cross-movable connecting member 16 is mounted externally to the support slide post 15 to form a kinematic pair with the support slide post 15. A second drive member 17 is connected to and drives the cross-movable connecting member 16. In a preferred embodiment, the support slide post 15 is positioned perpendicular to the base 4. Both the support slide post 15 and the cross-movable connecting member 16 can have a square cross-section. A shift fork 162 is provided on the side of the cross-movable connecting member 16 opposite the cantilever beam sleeve 12. The shift shaft slide hole 161 is provided on the shift fork 162. The shift shaft slide hole 161 can be an elongated, through-hole with a width of 140 mm to 160 mm.

[0028] The shift shaft 111 of the cantilever beam 11 passes through the slide groove 121 of the cantilever beam sliding sleeve 12 and is slidably connected to the shift shaft sliding hole 161 of the cross-moving connecting component 16 on the opposite side. When the cross-moving connecting component 16 moves linearly up and down, it is movably connected to the shift shaft 111 through the shift shaft sliding hole 161, which can drive the cantilever beam 11 to rotate a corresponding angle. The rotation angle is approximately 25°-30° upward from the surface of the base 4. The synchronous rotation connecting component 18 vertically and fixedly connects the cantilever beam 11 and the crossbeam slide 3. The synchronous rotation connecting component 18 includes a first notch 181 for fixing the crossbeam slide 3 and a second notch 182 arranged perpendicular to the first notch 181 for fixing the cantilever beam 11. When the cantilever beam 11 rotates, the crossbeam slide 3 is driven to rotate synchronously through the synchronous rotation connecting component 18.

[0029] The use of the cantilever beam 11 and the relatively movable cantilever beam sleeve 12 structure can make the length of the cantilever beam variable and extended, and the use of the supporting sliding column 15 and the relatively movable cross-movable connecting component 16 structure can change the angle between the cantilever beam and the horizontal plane. The change in the length and angle of the cantilever beam can be applicable to a wider range of tire diameter changes, that is, it can be applicable to tires of various diameters. When the tire diameter is small, the total length of the cantilever beam and the cantilever beam sleeve can be shortened and a smaller angle can be adopted. When the tire diameter is large, the total length of the cantilever beam and the cantilever beam sleeve can be extended and a larger angle can be adopted. In this way, the change in the total length of the cantilever beam and the cantilever beam sleeve and the change in the angle enable the tire disassembly and assembly machine to disassemble and assemble tires of various diameter specifications. The supporting sliding column is connected to the cross-moving connection, and the shift shaft of the cantilever beam passes through the sliding groove of the cantilever beam sliding sleeve and slides with the shift shaft sliding hole of the cross-moving connecting component on the opposite side. The supporting sliding column provides reliable support for the cantilever beam, and the axial movement of the cantilever beam sliding sleeve will not interfere with the up and down movement of the cross-moving connecting component. The angle and length of the cantilever beam can be adjusted at the same time to ensure that the cantilever beam will not vibrate or bend.

[0030] See also Figure 8-14As shown, in this embodiment, the outer periphery of the crossbeam slide 3 is provided with a crossbeam sliding sleeve 31 that is movable relative to the crossbeam slide 3. The cross-sections of the crossbeam slide 3 and the crossbeam sliding sleeve 31 can both be square. One end of a third driving component 32 is provided on the synchronous rotation connecting component 18 at the end of the crossbeam slide 3, and the other end is provided on the sleeve connecting portion 311 of the crossbeam sliding sleeve 31, and is used to drive the crossbeam sliding sleeve 31 to move along the axis of the crossbeam slide 3. A transverse pulley 33 is fixed to the crossbeam sliding sleeve 31, and one or more tire removal assemblies can be provided on the crossbeam sliding sleeve 31. The tire removal assemblies can be fixedly provided on the transverse pulley 33 or movably provided on the transverse pulley 33.

[0031] In this embodiment, the preferred embodiment is to arrange two sets of tire removing components, a first tire removing arm 2 and a second tire removing arm 5, side by side on the transverse pulley 33. The first tire removing arm 2 is fixedly arranged at one end of the transverse pulley 33, and the second tire removing arm 5 is arranged side by side with the first tire removing arm 2 at the other end of the transverse pulley 33 and can move laterally along the length direction of the transverse pulley 33.

[0032] In this embodiment, the first tire removal arm 2 includes a first outer sleeve 23 and a first inner slide arm 20 telescopically arranged in the first outer sleeve 23, and the fifth driving component 24 drives the first inner slide arm 20 to move in the first outer sleeve 23. A tire removal roller 21 is provided at the outer end of the first inner slide arm 20, and a rotating telescopic component 27 is also provided at the outer end of the first inner slide arm 20 near the tire removal roller 21. The rotating telescopic component 27 includes a telescopic cylinder 271 and a telescopic shaft 272 with a mounting hole 273 at the center. A tire removal hook 22 is provided at the outer end of the telescopic shaft 272. The shaft head of the tire removal hook 22 is provided with a through rotation positioning hole 251. A locking pin 25 for controlling the rotation of the tire removal hook 22 is provided at the position where the telescopic shaft 272 cooperates with the shaft head of the tire removal hook 22. After the tire removal hook 22 is installed in the mounting hole 273, its initial position is as shown in FIG. Figure 11 As shown, during installation, first pull out the locking pin 25 upwards, then rotate the tire removal hook 22 so that the mounting hole 273 is aligned with the locking pin 25, and finally lower the locking pin 25 so that its lower part enters the mounting hole 273 to lock it; if necessary, the tire removal hook 22 is located as shown in FIG. Figure 10In the tire removal working state shown, pull out the locking pin 25 again, rotate the tire removal hook 22 180°, so that the other side of the mounting hole 273 is aligned with the locking pin 25, and lower the locking pin 25 into the mounting hole 273 to lock it. A locking pin 26 for controlling the axial extension and retraction of the tire removing hook 22 is provided on the telescopic cylinder 271, and a positioning groove 261 is provided on the telescopic shaft 272. The locking pin 26 cooperates with the positioning groove 261 to control the extension length of the telescopic shaft 272. When the tire removing roller 21 is used, the tire removing hook 22 needs to be retracted to a position close to the telescopic cylinder 271. At this time, the tire removing hook 22 can be retracted by pulling up the locking pin 26 and pushing the telescopic shaft 272 into the telescopic cylinder 271. If the tire removing hook 22 needs to be used, the locking pin 26 is pulled up to pull out the telescopic shaft 272. When the positioning groove 261 reaches the position of the locking pin 26, the locking pin 26 falls into the positioning groove 261, and the tire removing hook 22 is fixed to its working position.

[0033] In this embodiment, the second tire removal arm 5 includes a second outer sleeve 53, a second inner sleeve 50 telescopically arranged in the second outer sleeve 53, and a sixth driving component 54 that drives the relative movement of the two. The outer end of the second inner sleeve 50 is provided with a tire removal pressure plate 51 and a tire removal member 52. The fourth driving component 36 drives the second tire removal arm 5 to move laterally along the length direction of the transverse pulley 33. An upper slide 56 is provided between the second outer sleeve 53 and the transverse pulley 33. The second outer sleeve 53 is fixed on the upper slide 56. The upper slide 56 moves on the transverse pulley track 331 of the transverse pulley 33. A locking pin 35 is provided at the front end of the second inner sleeve 50 to control the rotation of the tire removal pressure plate 51 and the tire removal member 52. After pulling up the locking pin 35, the positions of the tire removal pressure plate 51 and the tire removal member 52 can be rotated and changed. After the change, the locking pin 35 is lowered to lock the position.

[0034] The combined variable position tire removing device tire removing parts can be used to remove and install tires according to specific circumstances.

[0035] Application scenario 1: For the removal of large-diameter tires on aluminum alloy rims, the first tire removal arm 2 and the second tire removal arm 5 can be used in combination to complete the tire removal work. First, clamp the tire on the tire chuck 14, rotate the tire and use the tire removal roller 21 of the first tire removal arm 2 to loosen the tire bead. Then, insert the tire removal hook 22 into the tire bead and rotate the tire to pull the tire bead out of the rim. Next, insert the tire removal pressure plate 51 of the second tire removal arm 5 into the bead on the other side of the tire and rotate the tire. Finally, insert the tire removal pressure plate 51 of the second tire removal arm 5 into the bead on one side of the tire to push the tire, and insert the tire removal hook 22 of the first tire removal arm 2 into the bead on the other side of the tire to pull the tire, and work together to remove the tire from the rim.

[0036] Application scenario 2: For a medium-diameter tire with a steel rim, the first tire removal arm 2 can be used alone to complete the tire removal work. First, clamp the tire on the tire chuck 14, rotate the tire and use the tire removal roller 21 of the first tire removal arm 2 to loosen the tire bead. Then, insert the tire removal hook 22 into the tire bead to remove the retaining ring of the rim, and then rotate the tire to pull the tire bead out of the rim. Finally, pull the tire with the tire removal hook 22 to remove the tire from the rim.

[0037] Application scenario 3. For a large-diameter tire with a steel rim and a retaining ring, the first tire removal arm 2 and the second tire removal arm 5 can be used in combination to complete the tire removal work. First, move the second tire removal arm 5 close to the first tire removal arm 5 and clamp the tire, rotate the bull tongue tire removal piece 52 toward the tire, then insert the bull tongue tire removal piece 52 into the tire bead and rotate the tire to remove the rim retaining ring and then pull the tire bead out of the rim, then move the second tire removal arm 5 to the other side of the tire and insert the tire removal pressure plate 51 into the bead on the other side of the tire and rotate the tire, finally, use the second tire removal arm 5 to insert the tire removal pressure plate 51 into the bead on one side of the tire to push the tire, and insert the first tire removal arm 2 into the tire removal hook 22 on the other side of the tire bead to pull the tire, and work together to remove the tire from the rim.

[0038] In addition, the tire removing roller 21 of the first tire removing arm can also be used in combination with the auxiliary pressure roller 631 of the auxiliary tire removing device 6 to perform tire installation operations (see the following description).

[0039] Of course, for tires with smaller diameters, the tire removal roller 21, the tire removal hook 22, the tire removal pressure plate 51 or the ox tongue tire removal piece 52 can also be used alone for removal and assembly.

[0040] See also Figure 15-18As shown, in this embodiment, an auxiliary support device 6 that can move along the track is provided on the auxiliary slide 41 on the base 4, which is used to assist in moving, clamping the tire, and straightening the tire during the clamping or removal of large tires. The auxiliary support device 6 includes a tire-supporting pulley 61 at the bottom, and a slide that slides in cooperation with the auxiliary slide 41 is provided on the downward bottom surface of the tire-supporting pulley 61. A column 62 is vertically provided on the tire-supporting pulley 61, and an auxiliary pressure roller assembly 63 that can move up and down along the column 62 is provided. A seventh driving component 42 that drives the auxiliary support device 6 to move on the base 4 is provided below the tire-supporting pulley 61.

[0041] The auxiliary roller assembly 63 includes two sets of auxiliary slides 632 arranged parallel to the column 62. Each set of auxiliary slides 632 is provided with a set of auxiliary arms 633. A slide bushing 636 is provided on the side of the auxiliary arms 633 near the column 62. The auxiliary slides 632 penetrate into the slide bushing 636 and engage with each other, allowing the auxiliary roller assembly 63 to slide up and down along the auxiliary slides 632. The auxiliary arms 633 are connected to the auxiliary roller assembly 63 via a right-angled connection 637 on the side away from the column 62. Each set of auxiliary arms 633 is provided with an auxiliary roller 631 at one end. The column 62 is provided with a locking groove that can be inserted into the auxiliary arm 633. The locking groove includes a first locking groove 621 near the top of the column 62 and a second locking groove 622 away from the top of the column 62. A locking wheel 635 for fixing the auxiliary arm 633 and the locking groove is provided at one end of each set of the auxiliary arms 633 away from the auxiliary pressure roller 631 , and a connecting locking wheel hook plate 634 is provided between the two locking wheels 635 .

[0042] During tire removal or installation, if the auxiliary pressure roller assembly 63 is not locked in the second locking groove 622, first, loosen the two locking wheels 635 to separate the hook plate 634 from the locking wheel at one end, then move the auxiliary arm 633 to the second locking groove 622, and finally adjust the hook plate 634 and tighten the two locking wheels 635 to lock the auxiliary pressure roller assembly 63 in the second locking groove 622. If the auxiliary pressure roller assembly 63 is not locked in the first locking groove 621 during the tire support operation, the corresponding steps can be performed to lock the auxiliary pressure roller assembly 63 in the first locking groove 621.

[0043] When disassembling and installing a large-diameter tire, first place the tire on the tire supporting pulley 61 of the auxiliary disassembly device 6. For tires with a diameter exceeding 3500mm, the auxiliary pressure roller assembly 63 must be locked in the second locking groove 622. For tires with a diameter smaller than the above, the auxiliary pressure roller assembly 63 can be locked in the first locking groove 621. The auxiliary disassembly device can keep the tire stable during movement and clamping.

[0044] When installing the tire, since the steel wire in some large tires, especially the tire toe, is relatively hard, a single tire removal roller is difficult to smoothly press the tire bead into the rim of the rim. Two auxiliary pressure rollers 631 can be used in conjunction with the tire removal roller 21 to form three roller pressure points to easily install the tire. At this time, the locking groove of the auxiliary removal device needs to be determined according to the size of the tire.

[0045] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
