Description
Technical Field
[0001] This utility model relates to the technical field of wheel dismantling equipment, specifically to a wheel dismantling device for open-pit mining engineering vehicles. Background Technology
[0002] In the mining industry, open-pit mining vehicles account for 80% of the total equipment. Repairing wheel leaks, replacing oil seals, replacing brake pads, and fixing worn tires all require removing the dump truck tires before proceeding. The number of dump trucks requiring daily repairs is high. The current process for removing wheels from open-pit mining vehicles involves: first, using a screwdriver to remove the wheel nuts; then, using an iron bar to pry the wheel off the vehicle; next, transporting the wheel to a repair shop where a tire changer separates the tire from the rim, or moving the tire to a nearby rim and tire removal device (such as the special tool for removing rims and tires from scrapped vehicles, application number 202010300945.0) for tire-to-rim separation. So, the disassembly of the wheels of open-pit mining vehicles involves two processes: first, removing the wheels from the vehicle body, and second, separating the wheels (tire and rim). Obviously, there are convenient disassembly devices for separating the tires and rims, but removing the wheels from the vehicle body generally still requires manual labor with the help of iron bars, which is time-consuming, inefficient, and easily damages the rim and tire surface. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a time-saving, labor-saving, efficient, and wheel-removing device for open-pit mining engineering vehicles that is not prone to damaging the wheels.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A wheel removal device for open-pit mining engineering vehicles includes a support frame and outriggers. The support frame has a movable wheel at the bottom of its front end and a pry plate at the top of its front end. The support frame has a push-pull handle at its rear end. The top of the outriggers is connected to the middle of the support frame and has a support wheel at its bottom end. The upper surface of the support frame has a placement platform for holding the wheels.
[0006] As a further improvement to the above technical solution:
[0007] The middle of the placement platform is provided with a limiting post for inserting the wheel into the middle of the wheel.
[0008] The limiting post is cylindrical.
[0009] The placement platform is slidably mounted on the support frame and is equipped with a locking device for securing itself on the support frame.
[0010] The placement platform is provided with sliding sleeves on both sides, and the support frame is provided with slide rails on both sides. The sliding sleeves and slide rails are slidably connected in a one-to-one correspondence.
[0011] The locking element is a locking screw located on the sliding sleeve.
[0012] The pry bar is provided in two pieces, which are arranged at intervals along the width direction of the support frame.
[0013] The angle β between the skid and the support frame satisfies: 90°≤β≤135°.
[0014] The support leg is hinged to the support frame, and a diagonal brace is hinged to the middle of the support leg. The bottom surface of the support frame or the placement platform is provided with a limiting groove for the free end of the diagonal brace to be inserted.
[0015] The outrigger is provided with a receiving groove for accommodating the diagonal brace.
[0016] Compared with the prior art, the advantages of this utility model are:
[0017] This utility model discloses a wheel dismantling device for open-pit mining vehicles. In use, after removing the fixing nuts of the wheel to be dismantled, the wheel on one side of the vehicle is first lifted to a suitable height (generally 0.4-1cm off the ground) using a jack. Next, the wheel dismantling device is pushed to one side of the wheel, allowing the pry bar to extend under the wheel. Then, the push-pull handle is pressed down, causing the pry bar to pry the wheel outwards (generally achieved through repeated prying) until the wheel falls onto the placement platform. Finally, the wheel is transported to a tire changer for tire-to-rim separation. Using this wheel dismantling device to pry out and transport the wheel saves time and labor, is highly efficient, and minimizes damage to the wheel. Attached Figure Description

[0029] Example 1:
[0030] Figures 1 to 4This invention illustrates an embodiment of the wheel disassembly device for open-pit mining engineering vehicles. The wheel disassembly device for open-pit mining engineering vehicles in this embodiment includes a support frame 1 and a support leg 2. The support frame 1 has a movable wheel 3 at the bottom of its front end and a pry plate 4 at the top of its front end. The support frame 1 has a push-pull handle 11 at its rear end. The top of the support leg 2 is connected to the middle of the support frame 1 and a support wheel 5 is provided at its bottom end. The upper surface of the support frame 1 has a placement platform 6 for holding the wheel 8.
[0031] When using, such as Figure 4 As shown, after removing the fixing nuts of the wheel 8 to be removed, first use a jack to lift the wheel 8 on one side of the vehicle to a suitable height (generally 0.4-1cm off the ground); then, push the wheel removal device of this open-pit mining engineering vehicle to one side of the wheel 8 to be removed, so that the pry bar 4 extends under the wheel 8 to be removed; then, press down the push-pull handle 11 to pry the pry bar 4 upward, prying the wheel 8 outward (generally achieved by repeated prying) until the wheel 8 falls onto the placement platform 6; then, transport the wheel 8 to the tire changer to separate the tire from the rim. Using this open-pit mining engineering vehicle wheel removal device to pry out and transport the wheel 8 is time-saving and labor-saving, not only highly efficient, but also less likely to damage the wheel 8.
[0032] Furthermore, in this embodiment, the middle of the placement platform 6 is provided with a limiting post 7 for inserting and limiting the middle of the wheel 8. After the wheel 8 falls onto the placement platform 6, the limiting post 7 is inserted into the middle of the wheel 8 to limit the wheel 8, which helps to prevent the wheel 8 from falling off the placement platform 6.
[0033] Furthermore, in this embodiment, the limiting post 7 is cylindrical. The axial length of the limiting post 7 is shorter than the axial length of the wheel 8, typically, as... Figure 3 As shown, the axial length of the limiting post 7 is 1 / 4 of the axial length of the small wheel 8, which facilitates the unloading of the wheel 8 from the placement platform 6.
[0034] Furthermore, in this embodiment, the placement platform 6 is slidably mounted on the support frame 1 and is provided with a locking member 9 for securing itself on the support frame 1. The placement platform 6 is slidably mounted on the support frame 1, which facilitates movement and adjustment to accommodate wheels 8 of different diameters.
[0035] Furthermore, in this embodiment, sliding sleeves 61 are provided on both sides of the placement platform 6, and slide rails 12 are provided on both sides of the support frame 1. The sliding sleeves 61 and slide rails 12 are slidably fitted together in a one-to-one correspondence. The slide rails 12 serve as sliding guides for the placement platform 6, improving the stability of the movement and adjustment of the placement platform 6. Blocking members 13 can be provided on the support frame 1 at the front and rear of the placement platform 6 to limit the sliding adjustment range of the placement platform 6.
[0036] Furthermore, in this embodiment, the locking element 9 is a locking screw provided on the sliding sleeve 61. The locking screw is threadedly connected to the sliding sleeve 61. Tightening it will allow it to abut against the support frame 1 to lock the placement platform 6 on the support frame 1. Loosening it will allow the placement platform 6 to slide and adjust.
[0037] Furthermore, in this embodiment, there are two pry plates 4, which are arranged at intervals along the width direction of the support frame 1. This facilitates contact with both sides of the bottom of the wheel 8 (both sides of the wheel 8 axis) (the bottom of the wheel 8 is located in the space between the two pry plates 4), preventing the wheel 8 from rolling back and forth after being pried out.
[0038] Furthermore, in this embodiment, the angle β between the pry bar 4 and the support frame 1 satisfies: 90°≤β≤135°. Within this angle range, the pry bar 4 has a good prying effect on the wheel 8.
[0039] Furthermore, in this embodiment, the support leg 2 is hinged to the support frame 1, and a diagonal brace 21 is hinged to the middle of the support leg 2. A limiting groove 22 is provided on the bottom surface of the support frame 1 or the placement platform 6 for the free end of the diagonal brace 21 to be inserted. Thus, during transportation, the support leg 2 can be flipped to a forward-tilting or vertical position, and the diagonal brace 21 can be flipped to the limiting groove 22 where its free end is inserted, forming a triangular support effect on the lower part of the support frame 1. Preferably, the limiting groove 22 is provided on the support frame 1, and multiple grooves can be provided.
[0040] Furthermore, in this embodiment, the support leg 2 is provided with a receiving groove 23 for accommodating the diagonal brace 21. In this way, the diagonal brace 21 can be flipped and folded into the receiving groove 23, which facilitates the overall transportation.
[0041] It should be noted that this wheel removal device is mainly used for removing wheels from open-pit mining vehicles, including dump trucks, graders, loaders, water trucks, fuel trucks, commuter vehicles, wheeled excavators, and rescue vehicles (box trucks), etc. However, the mention of "open-pit mining vehicles" in the name does not limit the scope of application of the wheel removal device. It's just that for open-pit mining vehicles, the wheels are relatively large and heavy, and using this wheel removal device can achieve excellent time-saving, labor-saving, and high-efficiency results.
[0042] Example 2:
[0043] Figure 5 This invention illustrates one embodiment of the wheel removal device for open-pit mining engineering vehicles. The structure of this embodiment is basically the same as that of Embodiment 1, except that the front end of the pry bar 4 has an upward-curving arc-shaped edge 41. When the wheel 8 is pried, the arc-shaped edge 41 can abut against the inner bottom of the wheel 8, applying a good outward pushing force to the wheel 8, facilitating its removal. Of course, in other embodiments, the pry bar 4 can be designed with different structures according to actual needs to achieve the purpose of prying the wheel 8 out.
[0044] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
