Description

Technical Field

[0001] This utility model relates to the field of tire changing technology, and in particular to a quick tire changing bracket. Background Technology

[0002] Tires are crucial vehicle components, supporting the vehicle body and cushioning impacts. Changing tires on large agricultural machinery often requires auxiliary equipment due to their weight. Existing devices mostly use trolleys with lifting functions to move the tires, but these are not securely fixed during transport, requiring manual support to prevent tipping. This increases labor costs and poses a risk of tire tipping and injury. Therefore, a rapid tire-changing support system is proposed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as poor tire restraint, the need for manual support to prevent tipping during transfer, which wastes manpower, and the potential danger of tipping over. Therefore, this invention proposes a quick tire changing bracket.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A quick tire changing bracket includes two parallel sleeves and inserts, the inserts being inserted into the sleeves respectively, and one of the sleeves having a first support member at its top for supporting one side of the tire.

[0006] Two sleeves and two inserts are each welded with a square tube at an angled end. A second support member is installed inside the square tube to support the other side of the tire. The second support member can slide and bend along the horizontal direction of the square tube to support the tire or be stored in the square tube. The second support member and the first support member are located on both sides of the tire to prevent the tire from tipping over.

[0007] Two support mechanisms are installed on one side of each of the two square tubes to support the tire;

[0008] An adjustment mechanism is installed between the two sleeves and the two insertion tubes to adjust the distance between the two square tubes.

[0009] As a further embodiment of this utility model, the second support member includes a slider that slides inside the square tube and a fixing frame fixed to one end of the square tube. One end of the slider is hinged to a back plate, and a through hole is opened on one side of the back plate. A fixing bolt is inserted into the through hole and is threadedly connected to the fixing frame.

[0010] As a further embodiment of this utility model, a handle is welded to the top of the back plate, and a positioning plate is fixedly connected to one end of the square tube. When the back plate is stored, the fixing bolt can pass through the handle and be threadedly connected to the positioning plate to maintain stability between the back plate and the square tube.

[0011] As a further embodiment of this utility model, the first support member includes a support sleeve, an adjusting rod is inserted into the top of the support sleeve, a guide sleeve is fixedly connected to one side of the top of the adjusting rod, a horizontal plate is slidably connected inside the guide sleeve, and a through-hole set screw is threaded to one side of the support sleeve and one side of the guide sleeve, respectively for fixing the horizontal plate and the adjusting rod.

[0012] As a further embodiment of this utility model, the support mechanism includes a fixing block fixed to one side of the square tube, and a fixing plate rotatably connected to one side of one of the insertion tubes or sleeves on one side of the fixing block. Multiple support rollers are rotatably connected between the two fixing plates.

[0013] As a further embodiment of this utility model, the adjustment mechanism includes two connecting plates, which are respectively fixed between two sleeves and two insertion tubes. A through screw is rotatably connected to one side of the connecting plate located between the insertion tubes, and the screw thread passes through the other connecting plate.

[0014] As a further embodiment of this utility model, a column is welded between the two insertion tubes, and a through mounting shaft is rotatably connected to one side of the column. The mounting shaft is driven by a chain and sprocket. A rocker arm for driving the mounting shaft to rotate is detachably mounted on one side of the mounting shaft.

[0015] As a further improvement of this utility model, each square tube has two casters fixed to its bottom.

[0016] In this application, the device is moved to the area under the agricultural machinery tire to be removed. A rocker arm rotates the mounting shaft, which in turn drives a screw via a sprocket and chain. The screw drives two sleeves to move towards the insertion tube, causing the support rollers on both sides to contact the tire. After the tire is removed, the support rollers support the tire and pull it to rotate. After the tire is detached from the bolts on the agricultural machinery, the screw continues to rotate, causing the support rollers on both sides to move closer together, thus lifting the tire off the ground for easy transfer. During transfer, a backplate is pulled out from the square tube, and the angle of the backplate is fixed with a fixing bolt. The backplate then limits the tire's position, preventing it from tipping backward. Simultaneously, the support sleeve, adjusting rod, and cross plate limit the tire's position on the other side, preventing it from tipping forward. This eliminates the need for personnel to hold the tire during transfer, reducing manual labor and preventing injury from a tipping tire, thus improving safety. After the tire is in place, the backplate is lowered. Similarly, the new tire is placed on the device and moved to the side of the agricultural machinery for replacement.

[0017] Beneficial effects: In this utility model, the quick tire changing bracket, through the combined use of the first support member and the second support member, can simultaneously restrict both sides of the tire, prevent it from tipping over, avoid the need for personnel to hold the tire and move it, reduce manual labor, prevent the tire from tipping over and causing injury to personnel, and improve the safety of use.

[0018] In this utility model, the quick tire changing bracket is designed with a square tube installed at an angle, so that the back plate can also be tilted, thereby facilitating the limiting of tires of different diameters and making it convenient to use.

[0019] In this invention, the quick tire changing bracket has a retractable back plate, which reduces space waste when the device is not in use, and does not affect the installation and removal of tires after being retracted. Attached Figure Description
