[0032] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:

[0033] refer to Figure 1-6 , a sliding tire clamp, comprising:

[0034] Mounting frame 1; specifically, the rear side of the mounting frame 1 can be mounted to the front of the corresponding skid steer;

[0035] A vertical drive device 2 is provided on the mounting frame 1; specifically, the vertical drive device 2 can be provided as a rotary motor;

[0036] A linkage seat 3 is linked and sleeved on the vertical rotation output end 21 of the vertical drive device 2. The linkage seat 3 is provided with a plurality of guide shafts 31 extending outward at intervals in the circumferential direction. A plurality of guide shafts 31 are respectively slidably sleeved with clamping claws 4. The linkage seat 3 is provided with a telescopic drive device 32 for driving one of the clamping claws 4 to slide along the corresponding guide shaft 31. Specifically, the telescopic drive device 32 can be a drive device such as a telescopic oil cylinder or a pneumatic cylinder.

[0037] The rotating seat 5 is rotatably sleeved on the vertical rotating output end 21, and the rotating seat 5 includes a plurality of connecting parts 51 protruding from the circumferential outer side of the linkage seat 3 and corresponding to the adjacent guide shafts 31. A linkage rod 52 is rotatably connected between the clamping jaws 4 and the corresponding connecting parts 51, and the plurality of linkage rods 52 are rotationally symmetrical around the vertical rotating output end 21; when the telescopic driving device 32 drives one of the clamping jaws 4 to slide inward or outward, the corresponding linkage rod 52 drives the rotating seat 5 to rotate, and then drives the corresponding clamping jaws 4 to slide inward or outward synchronously through the remaining linkage rods 52.

[0038] The above structure is set up through the additional installation of the rotating seat 5 and the linkage rod 52, so that when the telescopic driving device 32 drives one of the clamping jaws 4 to slide inward, the corresponding linkage rod 52 pushes the rotating seat 5 to rotate and then pulls the corresponding clamping jaw 4 to slide inward synchronously through the remaining linkage rods 52; when the telescopic driving device 32 drives one of the clamping jaws 4 to slide outward, the corresponding linkage rod 52 pulls the rotating seat 5 to rotate and then pushes the corresponding clamping jaw 4 to slide inward synchronously through the remaining linkage rods 52. Thus, the sliding distance of several clamping jaws 4 inward or outward is adjusted synchronously, so as to stably adjust the size of the clamping area formed by several clamping jaws 4, avoid the different sliding distances of the clamping jaws 4 making several clamping jaws 4 unstable when clamping and releasing the tire, resulting in the situation that the tire falls off or the alignment fails in the process of clamping and carrying the tire or loosening the tire when aligning the wheel hub, and improves the stability of the tire clamp when working.

[0039] Specifically, the linkage seat 3 and the rotating seat 5 are both triangular in shape, the connecting portion 51 is located in the triangle of the rotating seat 5 and protrudes from the three sides of the linkage seat 3, and the plurality of guide shafts 31 extend outward along the three sides of the linkage seat 3, respectively. The telescopic driving device 32 is arranged in parallel on the side of one of the guide shafts 31 and has its two ends respectively hinged to one of the clamping jaws 4 and the side of the linkage seat 3 on the same side, thereby avoiding interference of the telescopic driving device 32 with the rotation of the rotating seat 5 and the clamping of the tire by the plurality of clamping jaws 4, and improving the stability of the telescopic driving device 32 driving the clamping jaw 4 to slide, the two ends of the linkage rod 52 are respectively hinged to the rear side of the clamping jaw 4 and the side of the connecting portion 51 close to the clamping jaw 4, and the plurality of linkage rods 52 rotate around the vertical transmission The output end 21 corresponds to the telescopic driving device 32, and the linkage seat 3, the rotating seat 5, and the linkage rod 52 are arranged in parallel. Specifically, in the present embodiment, one end of the linkage rod 52 is connected to the rear side of the clamping jaw 4, and the other end is connected to the connecting portion 51 located on the counterclockwise side of the clamping jaw 4 on the side close to the clamping jaw 4. The telescopic driving device 32 is arranged on the counterclockwise side of the corresponding guide shaft 31, so that when a clamping jaw 4 is driven by the telescopic driving device 32 to slide inward or outward, it drives one end of a linkage rod 52 to be pressed inward or pulled outward, and the other end of a linkage rod 52 pushes the rotating seat 5 in the counterclockwise direction or pulls the rotating seat 5 in the clockwise direction to rotate, so that the other ends of the other two linkage rods 52 are pulled or pushed, and then the other ends pull or push the corresponding clamping jaws 4 to slide inward or outward synchronously.

[0040] In order to improve the adaptability of the tire clamp, it also includes a transverse drive device 6 vertically arranged on the front side of the mounting frame 1, and the vertical drive device 2 is horizontally arranged above the mounting frame 1 and the bottom is linked with the transverse rotation output end 61 of the transverse drive device 6. Specifically, the transverse drive device 6 can be set as a rotary motor. Therefore, when the tire is clamped and carried to a certain position by a plurality of clamping claws 4 and needs to be aligned with the mounting surface, the transverse drive device 6 can be directly used to drive the vertical drive device 2 to rotate horizontally and align with the mounting surface, without the need to use a skid vehicle to continuously adjust the position for alignment, thereby improving the adaptability of the tire clamp and greatly improving the efficiency of tire installation.

[0041] In order to further improve the adaptability of the tire clamp, it also includes a limiting assembly 7, the upper outer fixed sleeve of the lateral drive device 6 is provided with a limiting plate 62 fixedly connected to the mounting frame 1, and the bottom outer fixed sleeve of the vertical drive device 2 is provided with a guide plate 22, the limiting assembly 7 includes a bracket 71 arranged on the top of the guide plate 22, a lever 72 rotatably arranged in the upper end of the bracket 71 on one side of the middle, and a limiting member 73 whose lower end can pass through the guide plate 22 and the limiting plate 62 in sequence and whose upper end is hinged to the middle of the lever 72 through a connecting rod 74, the upper and lower ends of the bracket 71 are respectively located on both sides of the limiting member 73, and a spring 75 is connected between the other side of the middle of the lever 72 and the lower end of the bracket 71; so that in the process of clamping and carrying the tire, the limiting member 73 can be clamped and moved by the lever 72. The spring 75 drives the lever 72 to be pressed down until the limiting member 73 passes through the guide plate 22 and the limiting plate 62 in sequence, so that the vertical drive device 2 and the horizontal drive device 6 are relatively limited, thereby preventing the horizontal rotation output end 61 of the horizontal rotation device from deflecting under the weight of the tire during the transportation process, resulting in unstable tire clamping; at the same time, when the tire clamp clamps the tire and needs to align with the mounting surface after the tire is in place, the lever 72 close to the spring 75 can be lifted until the limiting member 73 is separated from the limiting plate 62, so that the vertical drive device 2 can rotate relative to the horizontal drive device 6, and then when alignment is required, the vertical drive device 2 can be driven to rotate by the horizontal drive device 6 to drive the tire clamped by the plurality of clamps 4 to rotate horizontally to align with the mounting surface. Therefore, the addition of the limiting assembly 7 not only further improves the adaptability of the tire clamp, but also improves the stability of the tire clamp when it is working.

[0042] In order to improve the convenience and stability of the limiting assembly 7, the front middle part of the bracket 71 extends upward and then folds toward the rear side to form a limiting hook 711 arranged above the lever 72. The limiting hook 711 is located between the spring 75 and the connecting rod 74. The limiting hook 711 is used to limit the lever 72 from being lifted up until the limiting member 73 is separated from the limiting plate 62 but not separated from the guide plate 22. Therefore, by adding the limiting hook 711, it is possible to avoid the situation where the staff lifts the lever 72 excessively, causing the limiting member 73 to be separated from the guide plate 22, so that the limiting member 73 can always be inserted on the guide plate 22 and guided by it, so that after the staff releases the lever 72, the lever 72 can be stretched and reset by the elastic force of the spring 75, and the limiting member 73 can be stably inserted into the limiting plate 62, thereby improving the convenience and stability of the limiting assembly 7 when in use.

[0043] In order to improve the stability of the linkage seat 3 and the rotating seat 5 during operation, a shaft sleeve 23 located on the rear side of the linkage seat 3 is sleeved on the vertical rotating output end 21, and the front end of the shaft sleeve 23 protrudes outward to form a flange 231. The outer side of the shaft sleeve 23 is sleeved with a limiting plate 232 that is against the rear side of the flange 231 and blocked at the rear side of the middle part of the rotating seat 5. The linkage seat 3, the flange 231, and the limiting plate 232 are connected by a plurality of first bolt assemblies 24, thereby realizing stable linkage between the linkage seat 3 and the vertical rotating output end 21. The rotating seat 5 is rotatably sleeved on the outer side of the flange 231 and is located between the limiting plate 232 and the linkage seat 3, thereby avoiding interference between the clamping of the plurality of clamps 4 by the rotating seat 5, and limiting the lateral movement of the rotating seat 5 by the limiting plate 232 and the linkage seat 3.

[0044] In order to improve the stability of the rotating seat 5 during rotation, the linkage seat 3 includes a front plate 33 and a rear plate 34, a plurality of side plates 35 are fixed between the sides of the front plate 33 and the rear plate 34, a plurality of guide shafts 31 are inserted between the front plate 33 and the rear plate 34 and connected by a second bolt assembly 36, and the front plate 33 and the rear plate 34 are connected by a plurality of third bolt assemblies 37, and the rear ends of the second bolt assembly 36 and the third bolt assembly 37 correspond to the limiting plate 232 and are spaced apart at the front side of the rotating seat 5. Thus, the lateral displacement of the rotating seat 5 is further limited by the cooperation of the plurality of second bolt assemblies 36 and the plurality of third bolt assemblies 37 with the limiting plate 232, so as to avoid excessive skewness during the rotation of the rotating seat 5 and cause the mechanism to jam.

[0045] In order to improve the stability of the tire clamp, the front portion of the guide plate 22 is tilted forward and extends downward to form an abutment portion 221 that is abutted against the lower rear side of the limit plate 232. The abutment portion 221 prevents the limit plate 232 from being skewed relative to the vertical drive device 2, thereby preventing the sleeve 23 and the linkage seat 3 from being skewed relative to the vertical drive device 2, thereby improving the stability of the vertical drive device 2 driving the linkage seat 3 to rotate vertically, and the lateral drive device 6 driving the linkage seat 3 to rotate horizontally.

[0046] In order to further improve the stability of the rotating seat 5 when it rotates, the plurality of linkage rods 52 are respectively set as double-rod structures arranged at intervals in front and back, and the plurality of clamping jaws 4 are fixed at intervals at the rear to be flush with the rotating seat 5, and the hinge 41 and the side of the connecting portion 51 close to the clamping jaw 4 are respectively hinged in the two ends of the linkage rod 52. Thus, by arranging the plurality of linkage rods 52 flush with the rotating seat 5 and setting the linkage rod 52 as a double-rod structure, the stability of the linkage rod 52 in cooperation with the rotating seat 5 is improved, the deviation of the rotating seat 5 when it rotates is avoided, and the stability of the synchronous sliding of the plurality of clamping jaws 4 through the linkage rod 52 and the rotating seat 5 is improved.

[0047] In order to improve the clamping stability of the clamping jaws 4 , the distal ends of the clamping jaws 4 are folded forward to form a clamping portion 42 , and a plurality of latch teeth 421 are respectively provided at the front and both sides of the clamping portion 42 .

[0048] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
