However, due to the larger size and weight of off-road wheels, traditional methods such as manual handling or conveyor belt transport cannot accurately tilt and place them on top of the rim, leading to errors and low efficiency during the subsequent tire assembly process.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 4 : A clamping and conveying device for off-highway wheels includes a clamping frame 1 driven by a slide rail and a cylinder, capable of moving up and down and back and forth. The clamping frame 1 is provided with a left clamping arm 2 and a right clamping arm 3 with identical mirror structure. The right clamping arm 3 includes a clamping vertical arm 30 longitudinally arranged on one side of the front end face of the clamping frame 1. The clamping vertical arm 30 is tilted and swung by an inclined linkage mechanism 4 on the clamping frame 1. The lower end of the side wall of the clamping vertical arm 30 is fixed with a forward-extending clamping arm base 31. Two sets of rocker arm linkage mechanisms 5, which are mirror-arranged and used to clamp the side wall of the tire, are fixed on the clamping arm base 31.

[0020] During use, the clamping frame 1 moves up and down and back and forth via slide rails and cylinders. This movement is equivalent to the tire's movement from the conveyor line to the fixture where the wheel hub is placed during transport. A tilting linkage mechanism drives the clamping frame to tilt, allowing the tire to be tilted and placed above the wheel hub. Simultaneously, the rocker arm linkage mechanism 5 clamps and secures the tire, preventing it from falling off during movement.

[0021] Preferably, the clamping arm base 31 includes a clamping horizontal arm 32 that is fixed to the bottom of the clamping vertical arm 30, a horizontal arm base 33 is fixed on the clamping horizontal arm 32, and a plurality of horizontal arm base ribs 34 are fixed on the clamping horizontal arm 32 between the horizontal arm base 33 and the side wall of the horizontal arm base 33.

[0022] The clamping arm base 31 includes a clamping cross arm 33, which is fixed to a mounting bracket near the bottom of the clamping vertical arm 30. The mounting bracket is bolted to the end of the clamping cross arm 32. The clamping cross arm 32 is provided with a cross arm base 33 for mounting the rocker arm linkage mechanism 5. At the same time, a base rib 34 is provided between the cross arm base 33 and the clamping cross arm 32 to enhance the overall structural strength.

[0023] Preferably, the crossarm base 33 includes a mounting cavity 330 with a mounting side opening. The two rocker arm linkage mechanisms 5 are symmetrically arranged within the mounting cavity 330. Each rocker arm linkage mechanism 5 includes a first rocker arm cylinder 50 and a second rocker arm cylinder 51 hinged to the bottom of the mounting cavity 330. The end of the first rocker arm cylinder 50 is hinged to an "S"-shaped rocker arm 52, and the end of the second rocker arm cylinder 51 is hinged to the middle of the "S"-shaped rocker arm 51. A rocker arm connecting lug 53 is coaxially hinged to the hinge shaft. The rocker arm connecting ear 53 has an arc-shaped abutment groove 530 formed on one side.

The outer end of the clamping rocker arm 55 is fixed with a clamping vertical arm 550 for abutting against the tire sidewall. The inner end of the clamping rocker arm 55 is hinged to a main rocker arm 56. The inner side of the main rocker arm 56 is provided with an abutment end 560 that abuts against the abutment groove 530.

[0024] In the above structure, two sets of mirror-arranged rocker arm linkage mechanisms are provided in the mounting cavity 330. Each rocker arm linkage mechanism includes two sets of rocker arm cylinders. When the first rocker arm cylinder 50 is driven, it drives the rotation of the end of the S-shaped rocker arm 52. The S-shaped rocker arm then drives the movement of the straight rocker arm 54 to achieve different opening and closing angles. The second rocker arm cylinder 51 drives the rotation of the rocker arm connecting lug 53. At the same time, the abutment groove 530 on one side drives the abutment end 560 to move, and further drives the rotation of the main rocker arm 56. The main rocker arm 56 then drives the clamping rocker arm 54 to close or expand, realizing the clamping or releasing of the end, so that the two sets of rocker arm linkage mechanisms 5 can firmly grip the tire sidewall.

[0025] In addition, during implementation, the left and right clamping arms each contain two sets of rocker arm linkage mechanisms 5, which enable effective clamping and tightening on both sides.

[0026] Preferably, the clamping arm 550 is provided with a plurality of anti-slip textures 551.

[0027] Preferably, a synchronization frame 300 is fixed on each of the two clamping arms 30, and a synchronization rod 301 is fixed between the two synchronization frames 300. This enhances synchronization when tilting.

[0028] Preferably, the clamping frame 1 includes a top frame plate 10, a frame upright plate 11 fixed to the bottom of the top frame plate 10, and a frame diagonal rod 12 connected between the front end of the top frame plate 10 and the bottom of the frame upright plate 11. The tilting linkage mechanism 4 includes a first tilting cylinder 40 hinged to the top frame plate 10, the end of the first tilting cylinder 40 being hinged to the top of the clamping upright arm 30 via a connecting rod, a second tilting cylinder 41 hinged to the frame diagonal rod 12, an tilting connecting plate 42 hinged to the output end of the second tilting cylinder 41, and the end of the tilting connecting plate 42 being hinged to the rear side of the clamping upright arm 30.

[0029] Preferably, the bottom of the frame upright plate 11 is hinged with a support arm 43, and the support arm 43 is hinged to the middle of the inclined connecting plate 42.

[0030] In the above structure, the first tilting cylinder 40 drives the connecting rod, which enables the clamping arm 30 to tilt and swing up and down, and further utilizes the second tilting cylinder 41 to achieve bottom tilting and support.

[0031] Preferably, the clamping frame 1 is provided with a slider 13 fixed on the rear side and a slide 14 with a slide rail adapted to the slider 13 on the front side. A drive motor 15 is fixed on the top of the slide 14. The drive motor 15 is driven by a drive shaft 17 through a reducer 16. Drive helical gears are fixed at both ends of the drive shaft 17.

[0032] In the above structure, the device moves up and down by sliding a slider along a slide rail on the carriage. Lateral movement is achieved using a rack and pinion mechanism that matches the driving helical gear, driven by a motor.

[0033] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model.
