Description

Technical Field

[0001] This utility model belongs to the field of tire repair technology, specifically relating to a tire repair lifting machine. Background Technology

[0002] Tire lifts are a common piece of equipment in the automotive repair industry. They are primarily used to safely raise tires to a suitable height for repair. These machines significantly improve work efficiency, ensure worker safety, and reduce the physical labor required to manually lift tires.

[0003] Problems with existing technology:

[0004] Currently available tire repair lifts are inconvenient to use because tires vary in size and require manual adjustment. Furthermore, existing lifts cannot rotate the tires, further complicating tire repair. Utility Model Content

[0005] The purpose of this invention is to provide a tire repair lift that solves the problems of existing tire repair lifts, which require manual adjustment to suit different tire sizes and cannot be rotated for adjustment during repair, thus affecting the repair process.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A tire repair lifting machine includes a movable base frame, and a column is fixedly installed on the top of the movable base frame;

[0008] The back of the column is provided with a lifting mechanism, which drives the mounting rod to move the fixing mechanism vertically;

[0009] The fixing mechanism includes a housing and a rack. A second motor is fixedly installed on the back of the housing. The second motor drives a gear to mesh with the rack. A clamping assembly is fixedly connected to one end of the rack.

[0010] The clamping assembly includes a mounting plate, a cylinder, and a connecting plate. The cylinder pushes the connecting plate to move vertically, causing the connecting plate to swing through the connecting arm and the rotating stop.

[0011] The mounting rod is rotatably mounted to the lifting mechanism, and the fixing mechanism is fixedly connected to the mounting rod.

[0012] Both the rack and the clamping assembly are provided with two sets, with the two sets of racks located on both sides of the gear, and the racks are slidably installed with the housing.

[0013] A sliding rod is fixedly installed at the bottom of the mounting plate, so that the mounting plate is slidably connected to the housing, and a cylinder is fixedly installed at the bottom of the mounting plate.

[0014] The mounting plate is hinged to the top of a support arm, and a connecting arm is hinged between the support arm and the connecting plate.

[0015] The rack drive mounting plate drives the rotating stop to move, so that the rotating stop comes into contact with the tire.

[0016] The lifting mechanism includes a fixed base, a first motor, and a slide. The first motor is fixedly installed on the top of the fixed base. The first motor drives the sprocket to rotate the chain, causing the slide to move vertically.

[0017] The chain is fixedly installed with the slide block, and the slide block is slidably installed with the column.

[0018] The technical effects achieved by this utility model are as follows:

[0019] This invention utilizes a second motor mounted on the back of the housing, which drives a gear to rotate, causing a rack to move the mounting plate vertically. The movement of the mounting plate adjusts the vertical spacing of the rotating stop. Furthermore, the activation of a cylinder causes a connecting plate to push the support arm and rotating stop through the connecting arm for lateral spacing adjustment. This allows the device to automatically adjust the fixing mechanism during use, making it suitable for repairing tires of different sizes.

[0020] This utility model features a lifting mechanism installed on the back of the column. A first motor drives a sprocket to rotate, which in turn causes the chain to move the slide vertically. Since the fixing mechanism is rotatably mounted to the slide via a mounting rod, it can also drive the tire to move vertically, thus achieving a lifting effect. Simultaneously, under the action of the mounting rod and the slide, the fixing mechanism can drive the tire to flip, making tire maintenance more convenient. Attached Figure Description

Detailed Implementation

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] like Figure 1-4 As shown, a tire repair lifting machine includes a movable base frame 1, and a column 2 is fixedly installed on the top of the movable base frame 1;

[0029] The back of the column 2 is equipped with a lifting mechanism 3, which drives the mounting rod 4 to move the fixing mechanism 5 vertically;

[0030] The fixing mechanism 5 includes a housing 51 and a rack 55. A second motor 52 is fixedly installed on the back of the housing 51. The second motor 52 drives the gear 54 to mesh with the rack 55. A clamping component 53 is fixedly connected to one end of the rack 55.

[0031] The clamping assembly 53 includes a mounting plate 531, a cylinder 533, and a connecting plate 534. The cylinder 533 pushes the connecting plate 534 to move vertically, causing the connecting plate 534 to drive the rotating stop 536 to swing through the connecting arm 535.

[0032] See attached document Figure 1 In this embodiment, the mounting rod 4 is rotatably mounted to the lifting mechanism 3, and the fixing mechanism 5 is fixedly connected to the mounting rod 4.

[0033] In the above embodiment, the lifting mechanism 3 can cause the mounting rod 4 to drive the fixing mechanism 5 to move vertically, thereby lifting the tire 6 to a suitable maintenance height. At the same time, due to the action of the mounting rod 4 and the lifting mechanism 3, the fixing mechanism 5 can drive the tire 6 to rotate, thereby allowing the tire 6 to be adjusted at an angle, which facilitates the maintenance of the tire 6.

[0034] See attached document Figure 1 , Figure 2 and Figure 3 In this embodiment, both the rack 55 and the clamping assembly 53 are provided with two sets. The two sets of racks 55 are located on both sides of the gear 54, and the racks 55 are slidably installed with the housing 51.

[0035] In the above embodiment, the gear 54 can be rotated inside the housing 51 by the action of the second motor 52. Since the gear 54 meshes with the rack 55, the rack 55 can drive the clamping assembly 53 to move vertically.

[0036] Furthermore, the mounting plate 531 of the clamping assembly 53 is fixedly connected to the rack 55, and a slide bar is fixedly installed at the bottom of the mounting plate 531, so that the mounting plate 531 can be slidably connected to the housing 51.

[0037] Furthermore, a cylinder 533 is fixedly installed at the bottom of the mounting plate 531, and the support arm 532 is hinged to the mounting plate 531. A connecting arm 535 is hinged between the support arm 532 and the connecting plate 534. Therefore, when the cylinder 533 moves against the connecting plate 534, the support arm 532 can drive the rotating stop 536 to move, thereby causing the rotating stop 536 to abut against the tire 6.

[0038] See attached document Figure 1 , Figure 2 and Figure 3 In this embodiment, the lifting mechanism 3 includes a fixed base 31, a first motor 32 and a slide 35. The first motor 32 is fixedly installed on the top of the fixed base 31. The first motor 32 drives the sprocket 33 to drive the chain 34 to rotate, so that the slide 35 moves vertically.

[0039] In the above embodiment, the fixed base 31 is fixedly installed with the column 2, the slide 35 is slidably installed with the column 2, and the chain 34 is fixedly installed with the slide 35. Therefore, when the first motor 32 is started, the chain 34 can drive the slide 35 to slide vertically on the surface of the column 2, and then drive the tire 6 to move synchronously through the mounting rod 4 and the fixing mechanism 5.

[0040] The working principle of this utility model is as follows: After moving the device to a suitable position by moving the universal wheels at the bottom of the base frame 1, the first motor 32 is started to drive the sprocket 33 to rotate, thereby causing the chain 34 to drive the slide 35 to move vertically. The slide 35, through the mounting rod 4, drives the fixing mechanism 5 to move vertically to a suitable position, and then the tire 6 can be placed on one side of the fixing mechanism 5. By starting the second motor 52, the gear 54 is rotated, thereby causing the rack 55 to drive the mounting plate 531 to move vertically, thereby adjusting the vertical spacing of the rotating stop 536 and adjusting the vertical distance of the rotating stop 536. After the tire 6 is initially clamped, the connecting plate 534 can be moved vertically by starting the cylinder 533. The connecting plate 534, through the connecting arm 535 and the support arm 532, drives the rotating stop 536 to adjust the spacing laterally, thereby further clamping the tire. Then, the first motor 32 can be started to make the slide 35 lift the fixing mechanism 5 and the tire 6 to a suitable height through the mounting rod 4, so that the tire can be repaired. During the repair process, the fixing mechanism 5 can drive the tire 6 to rotate under the action of the mounting rod 4, making the repair more convenient.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
