When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] See also Figure 1 , shown is a tire clamp of the utility model, comprising a connecting rod 1, a frame 2 arranged at one end of the connecting rod 1, a limiting assembly arranged at an end of the frame 2 away from the connecting rod 1, and an anti-slip assembly arranged at an end of the frame 2 close to the connecting rod 1. The other end of the connecting rod 1 is used to connect a manipulator so that the manipulator can drive the entire tire clamp to move.

[0028] As an example, the limiting assembly includes limiting rollers 31 symmetrically arranged on both sides of the frame 2. In actual use, the two limiting rollers 31 are used to be inserted into the bottom of the vertically placed tire, and the tire is placed on the two limiting rollers 31 to achieve the transportation of the tire. Specifically, the limiting roller 31 includes a shaft portion 311 and a roller portion 312 sleeved on the shaft portion 311. One end of the shaft portion 311 is fixedly connected to the bottom of the frame 2, and the other end of the shaft portion 311 is rotatably connected to the roller portion 312 through a plurality of bearings. It should be understood that in order to ensure the stability of the tire placed on the two limiting rollers 31, the distance between the two limiting rollers 31 is less than the sum of the wheel rim diameter and the cross-sectional height of the tire. In other words, the distance between the two limiting rollers 31 is less than the total length of the tire in the radial direction, and at the same time, the total length of the roller portion 312 is greater than the cross-sectional width of the tire. When the tire is placed on the two limiting rollers 31, the circumferential surface of the roller portion 312 abuts against the tread of the tire. The design of the rotational connection between the roller portion 312 and the shaft portion 311 can assist the tire in rotating, thereby meeting the rotation requirements of employees when installing the tire on the car, thereby improving the convenience of tire installation.

[0029] As an example, Figures 2 to 3As shown, the anti-slip assembly includes a fixed seat 41 connected to the frame 2, a push-pull rod 42 rotatably connected to the fixed seat 41, and an anti-slip hook 43. The push-pull rod 42 is rotatably connected to the anti-slip hook 43 through a linkage block 44. The push-pull rod 42 drives the anti-slip hook 43 to rotate with the connection between the anti-slip hook 43 and the fixed seat 41 as the center. Specifically, a pulling force is applied to the push-pull rod 42, so that the end of the push-pull rod 42 away from the frame 2 moves toward the lower end of the frame 2, driving the anti-slip hook 43 to rotate, so that the anti-slip hook 43 rotates toward the side of the frame 2 away from the limiting roller 31. In this process, the angle between the anti-slip hook 43 and the horizontal direction varies in the range of 0°-130°. It should be noted that the initial state of the anti-detachment hook 43 is located on the side where the limiting roller 31 is located and the anti-detachment hook 43 is arranged parallel to the limiting roller 31. At this time, the spacing distance between the anti-detachment hook 43 and the limiting roller 31, that is, the total height of the frame is smaller than the total length of the tire in the radial direction, so that the two limiting rollers 31, the frame 2 and the anti-detachment hook 43 together form a limiting space for limiting the tire.

[0030] Furthermore, the push-pull rod 42 includes a handle portion 421 and a rotating portion 422 connected to the handle portion 421, one end of the rotating portion 422 away from the handle portion 421 is rotatably connected to the fixed seat 41, and one end of the rotating portion 422 close to the handle portion 421 is rotatably connected to one end of the linkage block 44, and a accommodating space for accommodating the linkage block 44 is provided on the rotating portion 422.

[0031] Further, the anti-disengagement hook 43 includes a first connection portion 431, a second connection portion 432 fastened to the first connection portion 431, and a hook portion 433 fastened to the second connection portion 432. One end of the first connection portion 431 away from the second connection portion 432 passes through the accommodation space on the rotating portion 422 and is rotatably connected to the fixed seat 41, and the portion of the first connection portion 431 located in the accommodation space is rotatably connected to the other end of the linkage block 44. In this way, when the push-pull rod 42 rotates toward the side away from the limiting roller 31, the push-pull rod 42 synchronously drives the anti-disengagement hook 43 to rotate toward the side away from the limiting roller 31 through the linkage block 44. The hook mouth of the hook portion 433 is arranged toward the side where the limiting roller 31 is located. In this embodiment, the cross section of the hook mouth of the hook portion 433 is L-shaped. When the tire is placed on the two limiting rollers 31, the push rod 42 is pushed to make the anti-detachment hook 43 be knocked down. At this time, the second connecting part 432 is in contact with the tire tread, and the hook mouth of the hook part 433 is buckled on the top of the side of the tire away from the frame, thereby realizing the limiting of the tire by the anti-detachment hook 43, preventing the tire from tipping over and detaching from the tire clamp of the utility model during transportation.

[0032] Furthermore, the tire clamp of the utility model is also provided with a guide roller assembly for assisting the rotation of the tire, and the guide roller assembly and the limiting roller assembly are arranged on the same side of the frame 2, and the guide roller assembly includes at least three guide rollers 51, and the guide rollers 51 are arranged around the center of the frame 2, and each guide roller 51 is arranged equidistant from the center of the frame 2. As a specific example, in this embodiment, three guide rollers 51 are provided on one side of the frame 2 where the limiting roller 31 is provided, specifically: one guide roller 51 is provided between the two limiting rollers 31, and one guide roller 51 is symmetrically provided on the frame 2 on both sides of the anti-disconnection hook 43. Furthermore, the guide roller 51 includes a shell and a roller, one side of the shell is fixedly connected to the frame 2, the roller is rollingly arranged in the shell along the radial direction of the tire, and the outer edge of the roller is higher than the shell. During actual use, the roller abuts against the tread of the tire. When the tire needs to be rotated to adjust the installation angle, the guide roller 51 on the side of the tire and the two limiting rollers 31 at the bottom of the tire can assist the tire in rotating to improve the convenience of tire rotation.

[0033] Furthermore, the frame 2 is provided with handles 6 at both ends of a side away from the limiting roller 31 , and the two handles 6 are symmetrically arranged.

[0034] Furthermore, control boxes 7 are respectively provided on opposite sides of the two handles 6, and the control boxes 7 are connected to the controller of the manipulator through external wires to control the opening and closing of the manipulator.

[0035] Furthermore, a material box 8 is provided on the side of the frame 2 away from the limiting roller 31. The material box 8 is used to load materials. In this embodiment, the material box 8 is used to load fastening screws for installing tires to avoid employees going back and forth to get materials, thereby improving the efficiency of tire installation.

[0036] In actual use, the working principle of the tire clamp of the utility model can be as follows: line-side material frames for stacking vertical tires are set on both sides of the tire installation line. In other words, the tire to be installed is turned 90 degrees and stacked in the line-side material frame. A certain distance is set between the tire and the ground so that the limiting roller can be inserted under the tire. The end of the connecting rod 1 away from the frame 2 is fastened to the manipulator at the tire installation line by bolts. The setting of the manipulator makes the entire tire clamp suspended in the air, and the entire tire clamp is controlled to move by the employees holding the handles 6 on both sides of the frame 2. Specifically, the push-pull rod 42 on the top of the frame 2 is pulled to open the anti-slip hook 43, even if the anti-slip hook 43 is located on the side where the handle 6 is located, to avoid affecting the placement of the tire on the limiting roller 31, the handles 6 on both sides of the frame 2 are held to control the tire clamp to move to the line edge material box, and the limiting rollers 31 on both sides of the frame 2 are inserted under the vertically placed tire, and the position of the tire is manually adjusted so that the tire at the bottom of the tire abuts against the circumferential surface of the roller portion 312 of the limiting roller 31, and the tread on one side of the tire abuts against the rollers of the three guide rollers 51 on the frame 2, and then the push-pull rod 42 is pushed to knock down the anti-slip hook 43, and the anti-slip hook 43 abuts against the tread of the tire, and the tire is located in the hook mouth of the anti-slip hook 43, so that the tire is limited in the limiting space between the anti-slip hook 43, the frame 2 and the two limiting rollers 31, to prevent the tire from tilting and falling during tire transportation. The handles 6 on both sides of the hand-held frame 2 are then used to move the entire tire clamp carrying the tire to the tire installation line, and the anti-detachment hook 43 is opened to carry out the tire installation process. During the installation process, the fastening bolts can be taken out from the material box 8 to pre-tighten the tire. Finally, the empty tire clamp is transferred to the line side material box again to load the next tire.

[0037] In summary, the beneficial effects of the tire clamp in the above-mentioned embodiments of the utility model are: simple structure, convenient operation, and high applicability. Specifically, a connecting rod for connecting a manipulator is provided on the frame, and the manipulator is used to assist the aerial movement of the tire clamp, so as to realize the semi-automatic use of the tire clamp, reduce the cost and maintenance cost, and improve the handling efficiency of the tire during the assembly process; further, by providing two limiting rollers and an anti-detachment hook on the frame to form a limiting space for limiting the tire, there is no need to clamp and carry the tire hub or the outer tread, thereby avoiding the phenomenon of scratching the tire tread, ensuring the assembly quality of the tire, and the tire can be installed by simply opening the anti-detachment hook, without removing the tire, reducing the operating hours for clamping or releasing the tire, and improving the installation efficiency; further, by adding a guide roller assembly to the frame to assist the rotation of the tire, the convenience of the tire rotation is improved, and a material box is added to the frame to avoid employees going back and forth to get materials, thereby greatly improving the installation efficiency and improving the assembly line rhythm.
