Description

Technical Field

[0001] The utility model belongs to the field of tire disassembly devices, in particular to a special buckle for disassembling tires of large-scale engineering machinery. Background Art

[0002] In order to facilitate mobility, large-scale construction machinery such as bulldozers, excavators, loaders, and rollers often directly install the working robotic arms on large vehicles. Once the tires of the large vehicles fail, the construction machinery will become unusable and the tires need to be repaired. Before repairing the tires, the tires need to be removed.

[0003] Currently, before repairing large engineering machinery tires, multiple pry bars are often required to remove the tires from the wheel hubs. This disassembly method is time-consuming, labor-intensive, and inefficient, which reduces the working efficiency of large engineering machinery.

[0004] Therefore, in order to solve the problem that the existing tire removal uses a pry bar as a tool, which is time-consuming, labor-intensive and inefficient, a special clip for removing tires of large engineering machinery can be designed. The outer clip and the inner clip cooperate to clamp the two sides of the inner ring, and the tension generated by tightening the steel rope with an external device can be used to remove the tire from the wheel hub, saving the time required for tire removal.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] See also Figures 1-6The utility model provides an embodiment: a special buckle for disassembling tires of large engineering machinery includes an outer buckle 1 and an inner buckle 2; it also includes a rotating shaft 3 and a steel wire rope 4. A notch 5 is opened on one side of the U-shaped outer buckle 1, and a tooth groove 6 is opened on the other end of the outer buckle 1 opposite to the notch 5. The inner buckle 2 is movably connected to the notch 5, and a tooth block 7 matching the tooth groove 6 is fixedly connected to one side of the inner buckle 2. The outer buckle 1 is plugged with a rotating shaft 3 that passes through the inner buckle 2 and the outer buckle 1, and the top of the inner buckle 2 is plugged with a ring-shaped steel wire rope 4. The large engineering machinery wheel is clamped by the outer buckle 1 and the inner buckle 2. On both sides of the inner ring installed on the inner side of the tire, the other end of the wire rope 4 is connected to the external winding device, and the wire rope 4 is wound and tightened by the equipment to drive the outer buckle 1 and the inner buckle 2 to pull the inner ring and the tire on the inner ring out of the wheel hub, thereby realizing the rapid disassembly of large-scale engineering machinery tires and improving the disassembly efficiency of large-scale engineering machinery tires. The tooth grooves 6 and the tooth blocks 7 match, which can enable the outer buckle 1 and the inner buckle 2 to clamp and fix the inner ring. The outer buckle 1 and the inner buckle 2 are movably connected to the outside of the rotating shaft 3 and can be rotated to change the angle, so that the outer buckle 1 and the inner buckle 2 can be installed at different positions of the inner ring.

[0021] See also Figure 5 In this embodiment, a limiting ring 8 close to the outer buckle 1 is fixedly connected to the bottom end of the rotating shaft 3, and a pin hole 9 passing through the rotating shaft 3 is opened on the rotating shaft 3. A pin 10 close to the outer buckle 1 is inserted into the pin hole 9. The outer diameter of the limiting ring 8 is larger than the outer diameter of the hole groove in which the rotating shaft 3 is inserted, which can prevent the rotating shaft 3 from being completely pulled out from the other side. The length of the pin 10 passing through the rotating shaft 3 is larger than the diameter of the hole groove, and can play the same role as a limiting block, realizing the limitation of the position of the rotating shaft 3 from both sides, and preventing the outer buckle 1 and the inner buckle 2 movably connected by the rotating shaft 3 from disintegrating.

[0022] See also Figure 6 In this embodiment, a fastening ring 11 is wrapped around the outside of the middle section of the wire rope 4, and a connecting hole 12 is opened on the inner buckle 2. The wire rope 4 passes through the connecting hole 12. The fastening ring 11 can divide the 4 turns of the wire rope into two parts, which is convenient for installing external equipment and makes the force of the 4 turns of the wire rope more concentrated.

[0023] When working, the processing personnel first places the inner buckle 2 in the slot 5, and then passes the rotating shaft 3 through the holes and grooves opened on the outer buckle 1 and the inner buckle 2, so that the limit ring 8 is close to one side, and then the pin 10 is passed through the pin hole 9 opened on the rotating shaft 3, so that the other side of the rotating shaft 3 is limited to prevent the outer buckle 1 and the inner buckle 2 from being separated, and then the wire rope 4 is passed through the connecting hole 12 opened on the inner buckle 2, and then the two ends of the wire rope 4 are connected to form 4 loops of wire rope, and the connection position is moved to the middle section, and a metal ring is sleeved on the outside of the middle section, and the metal ring is clamped with a clamp to make it fit tightly with the wire rope 4 and then welded to form a fastening ring 11;

[0024] The staff uses a jack to completely lift the tire to be removed off the ground, and then clamps the buckle composed of the outer buckle 1 and the inner buckle 2 onto the inner ring of the tire. According to the installation position of the buckle, the inner buckle 2 is rotated to adjust the angle so that the tooth groove 6 and the tooth block 7 are clamped in the structure of the inner ring to form a fixed structure. Then, all the 4 turns of the wire rope are connected together using a connecting ring, and an external winding device is connected to the other end. The buckle is pulled by the winding device to remove the inner ring and the tire on the inner ring from the wheel hub.

[0025] Through the above steps, the outer buckle 1 and the inner buckle 2 clamp the two sides of the inner ring installed on the inner side of the large engineering machinery tire, and the other end of the wire rope 4 is connected to the external winding device. The wire rope 4 is wound and tightened by the device, driving the outer buckle 1 and the inner buckle 2 to pull the inner ring and the tire on the inner ring out of the wheel hub, thereby realizing the rapid disassembly of the large engineering machinery tire and improving the disassembly efficiency of the large engineering machinery tire, so as to solve the problem that the existing tire disassembly uses a pry bar as a tool, which is time-consuming, labor-intensive and inefficient.
