DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The purpose of the utility model is to provide a tire lifting frame to solve the problems existing in the above-mentioned prior art, and can assist workers to more easily carry the tire to the chuck assembly, thereby reducing the labor intensity of the workers.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1-Figure 3As shown, the utility model provides a tire lifting frame 100, including a tire flipping frame 1 and a tire lifting frame 2, wherein the tire flipping frame 1 includes two curved special-shaped beams parallel to each other, and a plurality of parallel cross beams are fixed between the two curved special-shaped beams, so that the two curved special-shaped beams are fixed into an integrated structure, and the tire lifting frame 2 is a U-shaped frame structure. The tire lifting frame 2 is arranged on the outer side of the chuck assembly 200. The specific structure of the chuck assembly 200 is the same as the structure of the chuck assembly 200 in patent CN116852920A, so it is not repeated here. The rear end of the tire flipping frame 1 is hinged to the front end of the tire lifting frame 2, and the tire flipping frame 1 and the tire lifting frame 2 can rotate relative to each other. A lifting device is connected to the lower side of the rear end of the tire lifting frame 2, and the lifting device is used to drive the tire lifting frame 2 to rise and fall.

[0027] like Figure 3 As shown, the tire lifting frame 100 also includes a flip control outer tube 12 and a flip control inner tube 13, which are arranged at the rear end of the tire flip frame 1 and the front end of the tire lifting frame 2, and the flip control inner tube 13 is slidably connected to the inner side of the flip control outer tube 12. A long strip-shaped limiting slide 1201 is provided on the side wall of the lower end of the flip control outer tube 12, and a limiting pin hole 1301 is provided at the lower end of the flip control inner tube 13. A limiting pin shaft (not shown in the figure) is provided at the limiting pin hole 1301, and the limiting pin shaft slides up and down in the limiting slide 1201. A flip part 14 is connected to the rear end of one side of the tire flip frame 1. The flip part 14 can be understood as a plate extending from the rear end of the tire flip frame 1, which is an integrated structure with the tire flip frame 1, and the flip part 14 is provided with a flip control slide, and a flip control pin shaft 15 is provided at the upper end of the flip control inner tube 13, and the flip control pin shaft 15 is slidably connected in the flip control slide.

[0028] When the tire needs to be moved to the chuck assembly 200, the tire is first placed at the front end of the tire flip frame 1, and then the lifting device is started, which drives the tire flip frame 1 and the tire lifting frame 2 to rise synchronously. During the rising process, the flip control inner tube 13 will also move upward in the flip control outer tube 12, and the limit pin will also slide upward in the limit slide groove 1201. When the limit pin abuts against the upper end of the limit slide groove 1201, the flip control inner tube 13 can no longer move upward. Figure 3 As an example, since the lifting device will continue to move the tire flip frame 1 and the tire lifting frame 2 upward, and the flip control inner tube 13 cannot move upward, the flip control pin 15 will move along the Figure 3The lower right end of the middle flip control chute slides toward the upper left end, and as the flip control pin 15 slides, the tire flip frame 1 will rotate toward the tire lifting frame 2. During this process, a worker is required to assist, and the tire is moved from the tire flip frame 1 to the tire lifting frame 2, and finally installed on the clamping plate assembly 200 to complete the whole process. When the tire needs to be lowered, it is only necessary to control the lifting device to descend. As for the movement trajectory of the tire flip frame 1 and the tire lifting frame 2, it is opposite to the above trajectory, so it will not be repeated here.

[0029] In this embodiment, if Figure 2 As shown, a rectangular tire placing frame 3 is provided at the front end of the tire turning frame 1. Before the tire is transported and loaded onto the chuck assembly 200, the tire needs to be placed on the tire placing frame 3. Both sides of the tire placing frame 3 are tilted downward, so that it is more convenient for the staff to push the tire onto the tire placing frame 3, which is more labor-saving.

[0030] In this embodiment, if Figure 2 As shown, a plurality of first turning and transporting rollers 4 and a plurality of second turning and transporting rollers 5 are rotatably connected to the tire turning frame 1, the second turning and transporting rollers 5 are closer to the tire lifting frame 2 than the first turning and transporting rollers 4, and the length of the second turning and transporting rollers 5 is longer than the length of the first turning and transporting rollers 4. Specifically, the purpose of setting the first turning and transporting rollers 4 and the second turning and transporting rollers 5 is to change the sliding friction into rolling friction, thereby further reducing the resistance encountered by the staff when pushing the tire.

[0031] In this embodiment, similarly Figure 2 As shown, the front end of the tire lifting frame 2 is provided with a front lifting roller 6, and the rear end of the tire lifting frame 2 is provided with a rear lifting roller 7. The front lifting roller 6 and the rear lifting roller 7 are respectively located on the front and rear sides of the chuck assembly 200. The function of the front lifting roller 6 and the rear lifting roller 7 is also to facilitate the transportation and support of the tire.

[0032] It should be noted here that, regarding the specific connection method of the first flipping and transporting roller 4, the second flipping and transporting roller 5, the front lifting roller 6 and the rear lifting roller 7, it is necessary to install a U-shaped roller bracket at the corresponding positions on the tire flipping frame 1 and the tire lifting frame 2 by welding or screw fixing, and the two ends of the first flipping and transporting roller 4, the second flipping and transporting roller 5, the front lifting roller 6 and the rear lifting roller 7 are respectively rotatably connected to the two ends of the corresponding roller bracket.

[0033] In this embodiment, a lifting side roller 8 is provided on both sides of the tire lifting frame 2. The two lifting side rollers 8 are respectively located on the left and right sides of the chuck assembly, and their functions are also to transport and support the tire.

[0034] In this embodiment, the lifting device includes a lifting hydraulic cylinder 10, and the telescopic end of the lifting hydraulic cylinder 10 is fixed to the rear end of the tire lifting frame 2. Further, the lifting hydraulic cylinder 10 is also connected to a pedal control switch, and the lifting and lowering of the lifting hydraulic cylinder 10 are controlled by the pedal. Further, regarding the pedal control switch, it can adopt the pedal transmission mechanism in the "a tire disassembly and assembly device" disclosed in the existing patent number CN116729033A, and trigger two different relays respectively through the pressing plate, thereby controlling the lifting or lowering of the lifting hydraulic cylinder 10.

[0035] In this embodiment, a lifting guide device 11 is provided on both sides of the rear end of the tire lifting frame 2. Furthermore, two lifting guide devices 11 are respectively provided on both sides of the lifting hydraulic cylinder 10. The lifting guide device 11 includes a lifting guide outer tube and a lifting guide inner tube. The lifting guide inner tube is slidably connected to the inside of the lifting guide outer tube, and the upper end of the lifting guide inner tube is fixed to the lower surface of the rear end of the tire lifting frame 2. In actual use, as the tire lifting frame 2 rises or falls with the lifting hydraulic cylinder 10, the lifting guide inner tube also synchronously moves up and down in the lifting guide outer tube. By providing the lifting guide outer tube and the lifting guide inner tube, it can be ensured that the tire lifting frame 2 always maintains vertical up and down movement during the lifting process, and the problem of tilting will not occur.

[0036] In this embodiment, a hinge shaft 9 is fixed to the front end of the tire lifting frame 2. Specifically, the two ends of the hinge shaft 9 are fixed to the two sides of the front end of the tire lifting frame 2 by screws. The rear end of the tire flipping frame 1 is rotatably connected to the hinge shaft 9. Specifically, the hinge shaft 9 is provided with annular grooves for clamping the two ends of the rear side of the tire flipping frame 1. The two ends of the rear side of the tire flipping frame 1 are respectively provided with corresponding circular through holes that can be rotatably connected to the corresponding annular grooves.
