Technical Field

[0001] This utility model relates to the technical field of tire repair, and in particular to a large tire sidewall opening device. Background Technology

[0002] In the current open-pit mining industry, large-tonnage, wide-body vehicles are equipped with large tires. Because mine roads are mostly gravel surfaces, the transportation environment is quite harsh. During transportation operations, the tires bear huge loads and are frequently subjected to various impacts, which can easily lead to tire bursts and damage, accelerating tire wear. Timely repairs are essential to ensure the normal production and operation of the mine.

[0003] Repairing damaged tires requires removing the inner tube for repair, and inspecting and cleaning debris from inside and outside the outer tire to ensure stable and reliable tire performance after repair. However, mining wide-body truck tires are made of hard, tough, and bulky materials. Current repair methods mainly rely on manual operation to open the tire opening, remove the inner tube, and then complete a series of tasks such as cleaning and repair. This traditional method is not only time-consuming and labor-intensive, often resulting in uneven tire sidewall openings that affect the quality of subsequent repairs, but also poses certain safety hazards and urgently needs to be improved and its safety risks eliminated.

[0004] In view of this, the inventors specifically designed a large tire sidewall opening device, which led to this invention. Utility Model Content

[0005] The purpose of this application is to provide a device for opening large tire sidewall openings, which at least solves the problems of difficulty in opening the outer tire, low work efficiency, and safety hazards in the repair of large tire sidewall openings in mining trucks.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This application provides a large tire sidewall opening device, including a rectangular frame formed by welding horizontal bars, vertical bars, and uprights. The horizontal bars are used to place tires. A fixing component for fixing the tire sidewall opening is fixedly installed on one side of each horizontal bar, and a spreading component for opening the tire sidewall opening is hinged to the other side of each horizontal bar. A long handle is fixedly installed on the spreading component, and a fixing rod is fixedly installed on the vertical bar along the direction of the long handle. A ring is slidably connected to the long handle to stabilize the spatial position between the long handle and the fixing rod.

[0008] In a further embodiment, the fixing component has the same structure as the spreading component. The fixing component or spreading component includes a pair of vertical pipes, a horizontal pipe fixedly connected between the vertical pipes, and a fixing member provided on the horizontal pipe.

[0009] In a further embodiment, the fastener includes a hook.

[0010] In a further embodiment, the number of hooks is two.

[0011] In a further embodiment, the riser on the fixing component is fixedly provided with reinforcing ribs that are connected to the crossbar.

[0012] In a further embodiment, the free end of the long handle is retractably provided with an extension rod for increasing torque.

[0013] In a further embodiment, the extension rod and the long handle are fixed together by a pipe clamp.

[0014] In a further embodiment, a protective rubber sleeve is fitted onto the extension rod.

[0015] In a further embodiment, the long handle is fixedly provided with anti-slip texture.

[0016] In a further embodiment, the bottom of the vertical rod is threaded with a movable support.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] By setting up a "clamping-opening" structure including an opening component and a fixing component, and utilizing the lever principle, along with components such as a long handle, a telescopic extension rod, and a locking ring, the opening operation of large tire sidewalls becomes more labor-saving, stable, and safe. This overcomes the problems of low efficiency and high safety hazards caused by relying on manual prying in existing technologies. At the same time, the device has a simple structure and is easy to assemble and disassemble, making it suitable for various large tire repair scenarios.

[0027] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] like Figure 1 As shown, this embodiment discloses a large tire sidewall opening device, which is particularly suitable for the maintenance of large tires used in mining trucks. It aims to solve the problems of difficulty in opening the outer tire, low repair efficiency, and safety hazards in existing technologies. Through the application of this device, workers can easily, safely, and efficiently complete operations such as opening and fixing the tire sidewall opening and removing and cleaning the inner bag.

[0029] The device includes a cuboid frame 1 for overall support and positioning. The frame 1 is constructed by welding horizontal bars 11, vertical bars 12, and uprights 13. The design of the frame 1 ensures structural stability while facilitating transportation and placement. The horizontal bars 11 form a support area for securely placing tires requiring repair.

[0030] On one side of the frame 1, there is a fixing component 2 for limiting and fixing the tire sidewall opening, while on the other side, there is an operable opening component 3 connected by a hinge. This structural design forms a symmetrical "clamping-opening" mechanism, which utilizes the lever principle to apply force on one side while forming a fixed fulcrum on the other side, thereby realizing the opening and positioning of the tire sidewall opening.

[0031] like Figure 2 and Figure 4 As shown, the fixing component 2 and the spreading component 3 have the same structure, specifically including a pair of uprights 41, with a horizontal pipe 42 fixedly connected between them to enhance overall rigidity. Several fasteners 43, preferably hooks, are provided on the horizontal pipe 42 to engage with the edge of the tire opening. Two hooks are used to ensure even force application and prevent localized tearing or detachment. To further enhance the strength of the fixing structure, the uprights 41 on the fixing component 2 are also fixedly connected to the lower horizontal bar 11 via reinforcing ribs 5, further strengthening their support and torsional resistance, making them suitable for high-intensity use in harsh mining environments.

[0032] A long handle 6 is fixedly connected to the opening assembly 3. This long handle 6 is used by the operator to apply force to open the tire sidewall. In order to maintain the opening angle and ensure operational stability, a fixing rod 7 is provided on the vertical rod 12 in the corresponding direction. After operation, the long handle 6 and the fixing rod 7 are locked by the ring buckle 8, thereby keeping the tire sidewall opening in the open state and freeing the operator's hands to carry out subsequent repair or cleaning work.

[0033] like Figure 1 and Figure 3 As shown, to further optimize operating comfort and force application efficiency, the free end of the long handle 6 is equipped with a retractable extension rod 9. Operators can adjust the handle length according to their needs to obtain a greater torque, improving the efficiency and accuracy of opening. The extension rod 9 is fixed to the long handle 6 by a pipe clamp 10 to ensure that it will not shift or fall off during operation. A protective rubber sleeve 91 is also fitted onto the surface of the extension rod 9 to effectively improve grip and prevent slippage during operation. To further ensure safety, the surface of the long handle 6 is also equipped with anti-slip textures 61 to increase friction, ensuring stable operation even in oily or slippery environments.

[0034] In addition, in order to adapt to different terrains or working environments, the bottom of the vertical rod 12 is equipped with a movable support 14 by means of a threaded connection. This support can not only adjust the height of the overall device, but also effectively adapt to inclined or uneven ground, ensuring the overall stability of the device.

[0035] In summary, the large tire sidewall opening device of this application, through its reasonable structural design, solves the problems of difficulty in opening the outer tire, low work efficiency, and high safety hazards during the maintenance of large tires in mining trucks. Its compact structure, convenient operation, and reliable safety make it particularly suitable for rapid tire maintenance in harsh environments such as mines and quarries, demonstrating high practical value and promising prospects for widespread application.
