[0026] In order to better explain the present utility model for easy understanding, the present utility model will be described in detail below with reference to the drawings through specific embodiments. Among them, the orientation nouns such as "upper" and "lower" mentioned in this article are based on Figure 1 the orientation of

[0027] Referring to Figure 1 as shown, a tire clamping auxiliary tool includes a connecting seat 1 connected to a loader and a support frame 2 arranged on one side of the connecting seat 1. The support frame 2 includes a fixed frame 21 fixedly connected to the connecting seat 1, movable frames 22 arranged at both ends of the fixed frame 21, and a clamping driving member 23 arranged between the fixed frames 21. The clamping driving member 23 can drive the movable frame 22 to perform a linear reciprocating motion relative to or towards each other along its axis. Clamping structural members 3 are respectively arranged at both ends of the side of the movable frame 22 away from the fixed frame 21, and the movable frame 22 can drive the two clamping structural members 3 to move towards or away from each other to clamp the tire.

[0028] In this embodiment, a tire clamping auxiliary tool is provided. The clamping auxiliary tool can be relatively tightened or loosened according to the diameter of the tire. Specifically, by setting the movable frame 22 to be axially movable relative to the fixed frame 21, the clamping structural members 3 on both sides of the movable frame 22 are driven to move relatively or away from each other, so as to accurately clamp the automobile tire, adapt to tires of different diameters, and the clamping driving member 23 can control the clamping force and the clamping distance of the clamping structural members 3. Therefore, the adaptability is stronger, and the tire can be removed or aligned with the axle during tire replacement, so as to greatly improve the efficiency of tire replacement.

[0029] Further, the fixed frame 21 includes two relatively parallel and vertically arranged mounting plates 211. Four through holes 212 are formed in both mounting plates 211. Mounting sleeves 213 are fixedly installed between the four through holes 212. The four mounting sleeves 213 are successively provided with a first socket, a second socket, a third socket and a fourth socket from top to bottom. The first socket and the second socket are arranged in a left-right staggered manner, the third socket and the fourth socket are arranged in a left-right staggered manner, and the first socket and the third socket are located on the same side. Each socket communicates with its corresponding through hole 212. The setting of this structure can make the overall forming and installation process simple and highly operable.

[0030] Further, the first socket, the second socket, the third socket and the fourth socket are all provided with openings 4 communicating with the outside. The openings 4 are used to accommodate part of the movable frame 22. By setting the openings to cooperate with the setting of the wedge blocks 226, a good positioning and connection effect is achieved, and at the same time, the sliding of the movable frame 22 is ensured.

[0031] Further, the movable frame 22 includes a first slide bar 221, a second slide bar 222, a third slide bar 223 and a fourth slide bar 224 respectively inserted into the sockets of the mounting sleeve 213. The first slide bar 221 and the second slide bar 222 slide relatively or away from each other, the third slide bar 223 and the fourth slide bar 224 slide relatively or away from each other, the first slide bar 221 and the third slide bar 223 slide synchronously, and the second slide bar 222 and the fourth slide bar 224 slide synchronously. The movable frame 22 further includes connecting pieces 225 arranged on both sides of the mounting plate 211 and wedge blocks 226 fixedly connected to the connecting pieces 225. The wedge blocks 226 are integrally formed with the outer wall ends of their corresponding slide bars, and the wedge blocks 226 can be slidably installed relative to the openings 4. The mounting sleeve 213 is provided with a chute cooperating with the wedge blocks 226. This prevents the phenomenon of deviation during the sliding process. Moreover, the sliding can be better carried out through the setting of the slide bar 221 and the mounting sleeve 213.

[0032] Further, the clamping driving member 23 includes two driving oil cylinders 231 disposed between the mounting plates 211 and a reversing valve 232 disposed on the mounting sleeve 213 at the top. Both driving oil cylinders 231 are connected to the reversing valve 232 through pipelines. The reversing valve 232 can respectively control the displacement of the two driving oil cylinders 231 extending or retracting. The extending ends of the two driving oil cylinders 231 are oppositely arranged, and the extending ends of the two driving oil cylinders 231 are respectively connected to the connecting pieces 225 to drive the clamping structural members 3 on the two connecting pieces 225 to move relatively or away from each other. By controlling the reversing valve 232 through an external pilot valve, the extending amount of the driving oil cylinder 231 can be further controlled, and then the displacement of the connecting piece 225 moving relatively or away from each other can be controlled, so that the tire can be clamped and transported more precisely.

[0033] Further, both clamping structural members 3 include clamping columns 31 disposed on the upper and lower sides of the connecting piece 225. The clamping columns 31 each include a fixed column 311 fixedly connected to the connecting piece 225 and a rotating column 312 connected to the end of the fixed column 311 through a bearing 5. The rotating column 312 can rotate along its axis. The purpose of setting the bearing 5 is that the tire can be manually rotated under the condition of clamping the tire, and the operability is strong.

[0034] Further, anti-slip sleeves are sleeved outside both the fixed column 311 and the rotating column 312. Specifically, the anti-slip sleeve is a rubber anti-slip sleeve to ensure the stability during handling.

[0035] Further, the two clamping columns 31 are obliquely arranged. The clamping column 31 in the upper part corresponds to the position of the diameter, and the clamping column 31 in the lower part corresponds to the position of the lower chord line, which can better cooperate with the disassembly of the tire.
