Description

Technical Field

[0001] This utility model relates to the field of automotive maintenance equipment technology, and in particular to a combined variable-position tire changing device for a horizontal tire changing machine used for removing and installing large tires. Background Technology

[0002] Tire removal components are crucial parts of large tire changers. Chinese invention patent application CN105799433A discloses a large tire changer with a horizontal structure capable of handling large tires. This machine includes a set of tire removal arms, including a tire removal plate. Since tire removal involves the tire removal components contacting the rim, different rim materials and hardness require different tire removal components. Furthermore, the first step in tire removal involves using a tire removal roller to press down the tire bead or inserting a tire removal plate or hook into the bead. Because large tires are large in diameter and heavy, their bead rigidity is also high, making it difficult to insert the tire removal components during the process. Using a single tire removal component cannot effectively loosen the tire bead, affecting the efficiency and effectiveness of tire removal. In addition, a limited number of tire removal arms also contributes to the difficulty in handling large tires. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Please see Figure 1-7As shown, in this embodiment, a crossbeam sliding sleeve 31 is provided on the outer periphery of the crossbeam slide rail 3, and both the crossbeam slide rail 3 and the crossbeam sliding sleeve 31 can have square cross-sections. One end of the third driving component 32 is disposed on the synchronous rotation connecting component 18 at the end of the crossbeam slide rail 3, and the other end is disposed on the sliding sleeve connecting portion 311 of the crossbeam sliding sleeve 31, used to drive the crossbeam sliding sleeve 31 to move along the axis of the crossbeam slide rail 3. A transverse trolley 33 is fixed on the crossbeam sliding sleeve 31. One or more sets of tire-removing assemblies can be provided on the crossbeam sliding sleeve 31. The tire-removing assemblies can be fixedly disposed on the transverse trolley 33 or movably disposed on the transverse trolley 33.

[0025] In this embodiment, a preferred embodiment is that two sets of tire removal components, a first tire removal arm 2 and a second tire removal arm 5, are arranged side by side on the transverse trolley 33. The first tire removal arm 2 is fixedly arranged at one end of the transverse trolley 33, and the second tire removal arm 5, which can move laterally along the length direction of the transverse trolley 33, is arranged side by side with the first tire removal arm 2 at the other end of the transverse trolley 33.

[0026] In this embodiment, the first tire-removing arm 2 includes a first outer sliding sleeve 23 and a first inner sliding arm 20 telescopically disposed within the first outer sliding sleeve 23. A fifth driving component 24 drives the first inner sliding arm 20 to move within the first outer sliding sleeve 23. A tire-removing roller 21 is provided at the outer end of the first inner sliding arm 20. A rotary telescopic component 27 is also provided near the tire-removing roller 21 at the outer end of the first inner sliding arm 20. The rotary telescopic component 27 includes a telescopic cylinder 271 and a telescopic shaft 272 with a central mounting hole 273. A tire-removing hook 22 is provided at the outer end of the telescopic shaft 272. The shaft end of the tire-removing hook 22 has a through-hole rotary positioning hole 251. A locking pin 25 for controlling the rotation of the tire-removing hook 22 is provided at the location where the telescopic shaft 272 mates with the shaft end of the tire-removing hook 22. After the tire-removing hook 22 is inserted into the mounting hole 273, its initial position is as follows: Figure 4 As shown, during installation, first pull the locking pin 25 upwards, then rotate the tire removal hook 22 so that the mounting hole 273 aligns 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 in place; if it is necessary for the tire removal hook 22 to be positioned as follows... Figure 3In the tire removal working state shown, pull out the locking pin 25 again, rotate the tire removal hook 22 180º so that the other side of the mounting hole 273 is aligned with the locking pin 25, and put the locking pin 25 down so that it enters the mounting hole 273 and locks it. A locking pin 26 is provided on the telescopic cylinder 271 to control the axial extension and retraction of the tire removal hook 22. A positioning groove 261 is provided on the telescopic shaft 272. The locking pin 26 and the positioning groove 261 cooperate to control the extension length of the telescopic shaft 272. When the tire removal roller 21 is used, the tire removal hook 22 needs to be retracted to a position close to the telescopic cylinder 271. At this time, pulling up the locking pin 26 and pushing the telescopic shaft 272 into the telescopic cylinder 271 will retract the tire removal hook 22. If the tire removal hook 22 needs to be used, pulling up the locking pin 26 and pulling the telescopic shaft 272 outward will cause the locking pin 26 to fall into the positioning groove 261 when the positioning groove 261 reaches the position of the locking pin 26, and the tire removal hook 22 will be fixed in its working position.

[0027] In this embodiment, the second tire-removing arm 5 includes a second outer sliding sleeve 53, a second inner sliding arm 50 telescopically disposed within the second outer sliding sleeve 53, and a sixth driving component 54 for driving the relative movement of the two. The outer end of the second inner sliding arm 50 is provided with a tire-removing pressure plate 51 and a tire-removing tongue component 52. The fourth driving component 36 drives the second tire-removing arm 5 to move laterally along the length direction of the transverse trolley 33. An upper sliding plate 56 is provided between the second outer sliding sleeve 53 and the transverse trolley 33. The second outer sliding sleeve 53 is fixed to the upper sliding plate 56, and the upper sliding plate 56 moves on the transverse trolley track 331 of the transverse trolley 33. A locking pin 3 55 is provided at the front end of the second inner sliding arm 50 to control the rotation of the tire-removing pressure plate 51 and the tire-removing tongue component 52. Pulling up the locking pin 3 55 allows the tire-removing pressure plate 51 and the tire-removing tongue component 52 to be rotated and changed. After the change, lowering the locking pin 3 55 locks the position.

[0028] Depending on the specific circumstances, the combined variable-position tire removal device can be used to remove and install tires.
