[0001] This utility model relates to the technical field of excavator repair tools, specifically a user-friendly excavator equipment repair tool. Background Technology
[0002] An excavator (also known as a digger) is an earthmoving machine that uses a bucket to excavate materials above or below the machine's bearing surface and load them into transport vehicles or unload them into a stockpile. It is mainly used to handle soil, coal, silt, and pre-loosened rock. After long-term use, excavators need to be regularly maintained and repaired to ensure their proper functioning and extend their service life. Common tools used in maintenance and repair include wrenches for loosening bolts and nuts.

[0020] Please see Figures 1-4 In this embodiment of the utility model, an easy-to-use excavator equipment maintenance tool includes a maintenance tool body 1. The lower end of the maintenance tool body 1 is provided with a slot 2. By aligning the slot 2 with the nut or screw, disassembly can be completed, which is very convenient.
[0021] The main body 1 of the repair tool has a first wheel 7 and a second wheel 8 rotatably connected inside. The first wheel 7 and the second wheel 8 are connected by a belt 9. The lower end of the second wheel 8 is connected to the slot 2. The second wheel 8 can quickly disassemble the slot 2, making the repair equipment suitable for disassembling different screws and nuts. A rotating disk 3 is rotatably connected to the main body 1 of the repair tool. The lower end of the rotating disk 3 is fixedly connected to a first telescopic rod 5. The lower end of the first telescopic rod 5 is fixedly connected to the first wheel 7. The upper end of the rotating disk 3 is fixedly connected to a rotating rod 4. The rotating rod 4 can rotate the rotating disk 3, which in turn drives the first wheel 7 to rotate through the first telescopic rod 5. This, in turn, drives the second wheel 8 to rotate through the belt 9, thereby rotating the slot 2 and completing the disassembly and assembly of screws and nuts.
[0022] A second telescopic rod 6 is fixedly connected to the upper inner wall of the repair tool body 1. The lower end of the second telescopic rod 6 is rotatably connected to the second wheel 8. A spiral column 10 is threadedly connected to the upper end of the repair tool body 1. A connecting ring 12 is sleeved on the spiral column 10. Two connecting columns 13 are fixedly connected to the outer wall of the connecting ring 12. A slider 14 is fixedly connected to each of the two connecting columns 13. The slider 14 is connected to the first wheel 7 and the second wheel 8, but will not affect the rotation of the first wheel 7 and the second wheel 8. A handle 11 is fixedly connected to the spiral column 10. The spiral column 10 can be rotated by the handle 11. When the spiral column 10 rotates, it can move up and down based on the repair tool body 1, thereby completing the movement and storage of the slot 2.
[0023] The lower end of the main body 1 of the maintenance tool is rotatably connected to a rotating column 15, and a sealing plate 16 is fixedly connected to the rotating column 15. The sealing plate 16 can seal the slot 2.
[0024] The working principle of this utility model is as follows: When it is necessary to repair the excavator, the screws and nuts need to be removed. At this time, the matching slot 2 can be aligned with the nut, and then the rotating rod 4 can be used to rotate the rotating disk 3. When the rotating disk 3 rotates, the first telescopic rod 5 drives the first wheel 7 to rotate, and then the belt 9 drives the second wheel 8 to rotate synchronously, thereby realizing the rotation of the slot 2 and completing the rotation and removal of the nut. The entire device does not need to be rotated during the removal process, which is very convenient and easy to use in a confined space. The diameter of the first wheel 7 is larger than the diameter of the second wheel 8, so that the operator can use it with less effort. After use, the screw column 10 can be rotated by the handle 11. When the screw column 10 rotates, it can move upward based on the repair tool body 1, thereby driving the second wheel 8 to move upward through the connecting ring 12, connecting column 13 and slider 14, so that the slot 2 can be stored inside the repair tool body 1. Finally, the rotating column 15 rotates the closing plate 16 to complete the sealing of the slot 2, which has a good protective effect.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
