Description

Technical Field

[0001] This utility model relates to the field of tire retreading technology, and in particular to a rotatable tire retreading support device. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. Tires are usually mounted on metal rims, supporting the vehicle body, buffering external impacts, making contact with the road surface, and ensuring the vehicle's driving performance. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperatures during driving. Therefore, they must have high load-bearing capacity, traction capacity, and cushioning capacity. After prolonged use, tires will be damaged and need to be repaired to achieve the purpose of retreading.

[0003] A search revealed that Chinese patent CN221335579U discloses an auxiliary device for tire retreading, which includes a base plate, a clamping assembly connected to the base plate, a tire disposed within the clamping assembly, a movable plate slidably connected to the base plate, two sliding grooves formed within the base plate, a plurality of first limiting grooves formed within the sliding grooves, and a motor connected to the front of the movable plate.

[0004] In actual use, this patent has the following drawbacks:

[0005] In this patent, it is not convenient to flip the fixed tire. When repairing or refurbishing different positions of the tire, the tire must be removed from the fixing part, flipped to the position that needs to be refurbished or repaired, and then fixed again before the repair and refurbishment work can be carried out, which reduces the efficiency of repair and refurbishment. Utility Model Content

[0006] In view of the technical problems in the existing technology, it is not convenient to flip the fixed tire. When repairing and retreading different positions of the tire, the tire must be removed from the fixing part, flipped to the position that needs to be retreaded and repaired, and then fixed again before the repair and retreading work can be carried out, which reduces the efficiency of repair and retreading. This utility model provides a flipable tire retreading support device.

[0007] The technical solution adopted by this utility model is: a rotatable tire retreading support device, including a support frame and a rotatable assembly. The rotatable assembly is located on one side of the support frame. The rotatable assembly includes a transmission box, a rotating shaft, and a hydraulic rod. The rotating shaft is rotatably connected to the outer wall of one side of the transmission box, and a transmission gear is provided at one end of the rotating shaft inside the transmission box. The hydraulic rod is fixedly installed on the outer wall of one side of the transmission box, and a toothed plate is provided on the output shaft of the hydraulic rod. The toothed plate meshes with the transmission gear. A guide plate is fixedly installed on the inner wall of the transmission box, and the toothed plate is slidably sleeved on the outside of the guide plate. A mounting plate is provided at the other end of the rotating shaft away from the transmission gear.

[0008] Furthermore, a fixing component is provided on one side of the support frame. The fixing component includes a fixing frame and a fixing block. The fixing block is slidably connected to the outer wall of one side of the fixing frame. A lead screw is rotatably connected to the inner wall of the fixing frame through a bearing, and a driven bevel gear is fixedly provided at one end of the lead screw.

[0009] Furthermore, a motor is fixedly installed on the inner wall of the fixed frame, and a driving bevel gear is installed on the output shaft of the motor, wherein the driving bevel gear and the driven bevel gear mesh with each other.

[0010] Furthermore, the fixed frame has a sliding connection inside a movable block, and the movable block is threaded onto the outside of the lead screw.

[0011] Furthermore, a connecting block is provided on the outer wall of one side of the movable block, and the connecting block is connected to the fixed block.

[0012] Furthermore, a lifting block is slidably connected inside the support frame, the transmission box is fixedly installed on the outer wall of the lifting block, a hydraulic rod II is fixedly installed on the inner wall of the bottom of the support frame, and the lifting block is installed on the output end of the hydraulic rod II.

[0013] Furthermore, a base is provided at the bottom of the outer side wall of the support frame, and an installation screw passes through the internal thread of the base.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses a flipping component to flip the fixing frame, thereby flipping the tire after it is fixed on the fixing frame. When repairing different positions on the tire, there is no need to repeatedly disassemble and fix the tire, which can speed up the efficiency of tire inspection and refurbishment.

[0016] 2. Secondly, this utility model, through the fixing component, can drive multiple fixing blocks to expand outward simultaneously, which can quickly fix the tire from the inside of the tire without adjusting multiple fixing parts to fix the tire, making it more convenient.

A mounting plate 27 is provided at the other end of the rotating shaft 22 away from the transmission gear 23, which can realize the flipping of the tire fixed on the fixed frame 31.

[0028] Reference Figure 4 As shown, a fixing component 3 is provided on one side of the support frame 1. The fixing component 3 includes a fixing frame 31 and a fixing block 38. The fixing block 38 is slidably connected to the outer wall of one side of the fixing frame 31. A lead screw 32 is rotatably connected to the inner wall of the fixing frame 31 through a bearing. A driven bevel gear 33 is fixedly provided at one end of the lead screw 32. When the driven bevel gear 33 rotates, it can drive the lead screw 32 to rotate.

[0029] Furthermore, a motor 34 is fixedly installed on the inner wall of the fixed frame 31, and a driving bevel gear 35 is installed on the output shaft of the motor 34. The driving bevel gear 35 and the driven bevel gear 33 mesh with each other.

[0030] Furthermore, a movable block 36 is slidably connected inside the fixed frame 31, and the movable block 36 is threaded onto the outside of the lead screw 32. When the lead screw 32 and the movable block 36 are threaded together, the movable block 36 can be driven to move axially on the lead screw 32.

[0031] Furthermore, a connecting block 37 is provided on the outer wall of one side of the movable block 36, and the connecting block 37 is connected to the fixed block 38. When the connecting block 37 moves, it can synchronously drive the fixed block 38 to move.

Lifting block 5 simultaneously raises and lowers transmission box 21 and fixed frame 31, allowing for height adjustment of fixed frame 31 to accommodate tire repair and retreading workers of different heights. The tire is placed over several fixed blocks 38. Motor 34 is activated to drive active bevel gear 35 to rotate and mesh with driven bevel gear 33. Driven bevel gear 33 drives screw 32 to rotate and thread moving block 36. Moving block 36 simultaneously drives connecting block 37 and fixed block 38 to move axially on screw 32, allowing several fixed blocks 38 to expand outwards simultaneously, supporting the inner ring of the tire and thus fixing it. When different positions of the tire need to be inspected and the tire needs to be flipped, hydraulic rod 24 is activated to move toothed plate 25 and mesh with transmission gear 23. Transmission gear 23 drives rotating shaft 22 and fixed frame 31 to rotate, thus rotating the tire fixed on fixed frame 31. Tire inspection and retreading can be performed on different positions without disassembling, flipping, and re-fixing the tire, resulting in higher efficiency.
