[0034] See Figures 1-3 , a hoisting device for wheel assembly, including a connected hanging mechanism 1 and a clamping mechanism 2. The clamping mechanism 2 extends in the vertical direction. The clamping mechanism 2 is used for clamping a wheel. The clamping mechanism 2 includes a connected frame body one 21 and a frame body three 25 in the vertical direction. A hanging plate 23 is arranged on the frame body three 25. The hanging plate 23 is connected with the hanging mechanism 1. It also includes a frame body two 24 arranged at one end of the frame body three 25 away from the hanging mechanism 1 and connected with the frame body one 21. It further includes a rotary support mechanism 3 and a limiting mechanism 4 perpendicular to the extending direction of the clamping mechanism 2. The rotary support mechanism 3 is arranged at one end of the frame body one 21 away from the frame body two 24. The limiting mechanism 4 is arranged at one end of the frame body one 21 close to the frame body two 24. The rotary support mechanism 3 is used for supporting the wheel and enabling the wheel to rotate axially. The limiting mechanism 4 is used for fixing the wheel to prevent the wheel from moving during hoisting.

[0035] When using this hoisting device for wheel assembly to hoist a wheel, the circumference of the wheel is placed on the rotary support mechanism 3, and the wheel is limited by the limiting mechanism. Subsequently, the hoisting device with the wheel placed thereon is lifted by the hanging mechanism 1 for wheel assembly.

[0036] The frame body 1 (21) has a square structure, and the frame bodies 2 (24) and 3 (25) have angular structures, enabling effective clamping of the wheel and improving the structural stability of the hoisting device. The frame body 1 (21), the frame body 2 (24), and the frame body 3 (25) are welded by square steel pipes, rectangular steel pipes, and circular steel pipes. At one end of the frame body 1 (21) and the frame body 2 (24) close to the wheel, a support member 22 is provided for supporting the wheel. The support member 22 is preferably a spherical support seat, which can improve the supporting force for the wheel while avoiding damage to the wheel tire.

[0038] The rotary support mechanism 3 includes a rotary handle 31 and a rotary support assembly 32. The rotary support assembly 32 is used to support the wheel. The rotary handle 31 is arranged at the end of the rotary support assembly 32 away from the wheel. The rotary handle 31 controls the rotary support assembly 32 to rotate axially, thereby driving the wheel to rotate axially, so that the mounting holes on the wheel are aligned with the fixing bolts on the rear axle, thus realizing the assembly of the wheel. The rotary support assembly 32 includes a support shaft 321 connected to the rotary handle 31 and a support shaft sleeve 323 sleeved on the outer wall of the support shaft 321. At one end of the support shaft 321 away from the rotary handle 31, a rubber roller with an iron core 324 is connected. The rubber roller with an iron core 324 is used to carry the bottom of the wheel. At both ends of the support shaft 321, bearings 322, a hole-type snap ring 325, and a shaft-type snap ring 326 are also provided. The hole-type snap ring 325 is a hole-type snap ring, and the shaft-type snap ring 326 is a shaft-type snap ring. The hole-type snap ring is used to limit the bearings 322 at both ends, and the shaft-type snap ring is used to limit the position of the support shaft 321, enabling it to rotate reliably under the drive of the rotary handle 31.

[0039] The limiting mechanism 4 includes a first limiting rod 41 and a second limiting rod 43 that are perpendicular to each other. The second limiting rod 43 is of an L-shaped structure to fix the wheel. Eight first limiting holes 45 are arranged at intervals on the first limiting rod 41, and four second limiting holes 46 are arranged at intervals on the second limiting rod 43. A first limiting sleeve 47 is sleeved on the outer wall of the first limiting rod 41, and a second limiting sleeve 48 is sleeved on the outer wall of the second limiting rod 43. Openings are provided at the upper parts of the first limiting sleeve 47 and the second limiting sleeve 48. The second limiting sleeve 48 is connected to the first frame body 21, and the end of the second limiting rod 43 is connected to the first limiting sleeve 47. A first limiting pin 42 and a second limiting pin 44 are also included. The first limiting pin 42 is inserted into the first limiting hole 45 through the opening at the upper part of the first limiting sleeve 47, and the second limiting pin 44 is inserted into the second limiting hole 46 through the opening on the second limiting sleeve 48, so as to limit wheels with different diameters and widths, playing a role in safety protection.

[0040] A handle 49 is arranged at the end of the first limiting rod 41 away from the wheel, so as to facilitate the adjustment of the first limiting rod 41 and thus limit wheels with different widths.

[0041] The hanging mechanism 1 includes a hanging ring 12 and a hanging strap 11. The hanging ring 12 and the hanging strap 11, and the hanging strap 11 and the hanging plate 23 are detachably connected through shackles 13.

[0042] When using this hoisting device to hoist the wheel, use the workshop hoisting equipment to hang the hoisting device to the wheel storage area, adjust the rotating support assembly 32 to the bottom of the wheel and support the bottom of the wheel, and make the wheel in close contact with each support member 22 on the first frame body 21 and the second frame body 24. According to the different specifications and models of the wheels, adjust the limiting mechanism 4 to reliably limit the wheels to prevent them from falling off. Specifically, by adjusting the positions of the two second limiting rods 43 in the second limiting sleeve 48, the two first limiting rods 41 can be driven to approach or move away from each other, which is applicable to wheels of different diameters. According to the diameter of the wheel, the second limiting holes 46 at the corresponding positions are made to correspond to the openings in the upper part of the second limiting sleeve 48, and the second limiting pin 44 is inserted into the opening in the upper part of the second limiting sleeve 48 and the corresponding second limiting hole 46, so as to realize the positioning of the second limiting rod 43; then according to the width of the wheel, adjust the two first limiting rods 41 to approach or move away from the wheel, so that the first limiting holes 45 at the corresponding positions are made to correspond to the openings in the upper part of the first limiting sleeve 47, and the first limiting pin 42 is inserted into the opening in the upper part of the first limiting sleeve 47 and the corresponding first limiting hole 45, so as to realize the limitation of the first limiting rod 41. At this time, the L-shaped first limiting rod 41 clamps and fixes the wheel, so that the wheel can be reliably limited and prevented from falling off. Subsequently, use the hoisting equipment to hang the hoisting device with the wheel fixed thereon, and hoist the wheel to the whole machine assembly area for assembly. During assembly, rotate the rotating handle 31 to make the rotating support assembly 32 rotate, thereby driving the wheel to rotate axially to adjust the assembly position of the wheel, so as to facilitate the assembly of the rear wheel on the rear axle of the whole machine.

[0043] Using the hoisting device for wheel assembly provided by the present utility model can meet the hoisting operation requirements for the rear wheel assembly of various tractor models, ensure the safety and reliability of the assembly operation, and avoid scratching the wheel rim, tire and the rear wheel cover of the cab during hoisting operation.
