[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figures 1 to 2 As shown: This utility model is a work stand for the maintenance of construction machinery. It addresses the technical problems of long clamping and installation time and low efficiency in existing shaft maintenance techniques. It achieves lateral adjustment to accommodate different levels of shaft maintenance, and longitudinal height adjustment for convenient maintenance. Furthermore, the adjustable support structure of the lateral adjustment bracket 1 provides a stable maintenance platform. The technical solution adopted in this patent includes a lateral adjustment bracket 1 and longitudinal adjustment support rods 2. The lateral adjustment bracket 1 has symmetrically arranged longitudinal adjustment support rods 2 on both sides. Support frames 3 are bolted to the top of the longitudinal adjustment support rods 2 on both sides. The top of the support frames 3 has a circular... An arc-shaped clamping seat 14 is provided, and an arc-shaped clamping seat 25 is provided on the upper part of the arc-shaped clamping seat 14. The arc-shaped clamping seat 14 and the arc-shaped clamping seat 25 are detachably installed through side ears. Screw holes 16 are symmetrically opened on both sides of the arc-shaped clamping seat 14. Adjusting bolts 17 are threaded into screw holes 16. The adjusting bolts 17 pass through the arc-shaped clamping seat 14 and are rotatably installed with clamping plate 11. A screw hole 22 is opened on the top of the arc-shaped clamping seat 25. Adjusting bolts 23 are threaded into screw holes 22. The adjusting bolts 213 pass through the arc-shaped clamping seat 25 and are rotatably installed with clamping plate 24. The two clamping plates 11 and one clamping plate 24 together form a triangular clamping area.

[0017] The specific usage is as follows: By adjusting the lateral adjustment bracket 1 horizontally, maintenance support for shafts of different lengths is achieved. The lateral adjustment bracket 1 is also expanded to provide stable support for the maintenance bracket. The longitudinal height of the support rod 2 is adjusted to meet maintenance height requirements, facilitating convenient shaft maintenance. When placing the shaft, first remove the arc-shaped clamping seat 2 5, then simultaneously tighten the adjusting bolt 1 7, and push the clamping plate 1 11 upwards at an angle. After adjusting the clamping plate 1 11, place the shaft to be repaired. The two clamping plates 1 11 at the bottom of the shaft provide support. The device has side ears on both sides of the arc-shaped clamping seat 25 and the arc-shaped clamping seat 14, which are fixedly installed by bolts. By adjusting the adjusting bolt 213, the clamping plate 214 is moved downward, so that the clamping plate 214 clamps and installs the shaft. Since the clamping plate 11 is rotatably installed with the adjusting bolt 17 and the adjusting bolt 213 is rotatably installed with the clamping plate 214, the clamping plate 11 and the clamping plate 214 can be fitted to clamp the shaft, making the clamping more stable. It can be used for repair of coating process, welding, and shaft scratches and cracks.

[0018] In at least one implementation, the longitudinal adjustment support rod 2 includes an adjustment rod 15 and an adjustment rod 16. The adjustment rod 15 is fixedly installed with the transverse adjustment bracket 1, and the adjustment rod 15 and the adjustment rod 16 are slidably telescopically installed and limited by an elastic component. Specifically, by sliding the adjustment rod 16 longitudinally, and by limiting the adjustment rod 15 and the adjustment rod 16 with an elastic component, the height of the maintenance frame can be adjusted to meet the shaft maintenance height requirements.

[0019] In at least one embodiment, limiting holes 17 are equidistantly arranged on one side surface of adjusting rod 15. Adjusting rod 16 is provided with a plug-in sleeve 21 coaxially arranged with the limiting holes 17. A return spring 22 is sleeved on the outside of the plug-in sleeve 21. The bottom end of the return spring 22 is fixedly connected to the surface of adjusting rod 16. A shaft pin 23 is inserted into the limiting holes 17 and the inside of the plug-in sleeve 21. A plug-in handle 24 is provided on one side of the shaft pin 23 extending out of the plug-in sleeve 21. The plug-in handle 24 is positioned relative to the plug-in sleeve 21. The surface is fixedly connected to the top of the return spring 22; specifically: when sliding the second adjusting rod 16 upward, first pull the first shaft pin 23 outward, the first shaft pin 23 disengages from the first limiting hole 17, lift the second adjusting rod 16, after adjusting to the preset height, release the plug handle 24, and the return spring 22 retracts to make the first shaft pin 23 insert into the first limiting hole 17. The first shaft pin 23 is inserted into the first limiting hole 17 and the plug-in cylinder 21, forming a fixed sliding position of the second adjusting rod 16, thereby realizing the adjustment of the longitudinal height of the maintenance bracket.

[0020] In at least one implementation, to ensure the stable installation of adjusting rod 15 and adjusting rod 26, two insert tubes 21 are used to penetrate adjusting rod 26; this ensures that adjusting rod 26 is stably installed on adjusting rod 15, thus strengthening the support of the maintenance bracket.

[0021] In at least one embodiment, the lateral adjustment bracket 1 includes longitudinal rods 25 distributed on both sides of the lateral direction. The longitudinal rods 25 are fixedly connected to the adjustment rod 15. A telescopic rod is provided between the longitudinal rods 25. The telescopic rod includes a support rod 26 fixedly connected to one side of the longitudinal rod 25. A second support rod 27 is slidably connected inside the support rod 26. The second support rod 27 is fixedly connected to the longitudinal rod 25 on the other side. Screw holes 31 are equidistantly formed on the surface of the support rod 26. Positioning bolts are threaded into the screw holes 31 to limit and fix the distance at which the second support rod 27 slides out. Specifically... To achieve shaft length adaptation during maintenance, a telescopic rod is installed between the longitudinal rods 25 on both sides. By adjusting the length of the telescopic rod, the length of the lateral adjustment bracket 1 can be adjusted, adapting to the shaft length support installation and allowing the lateral adjustment bracket 1 to extend. This increases the overall support surface of the maintenance bracket and improves its stability. The telescopic rod 27 is adjusted by inserting a support rod 27 into the inside of the support rod 26. Screw holes 31 are equally spaced on the surface of the support rod 26, and the screw holes 31 are threaded with positioning bolts to fix the telescopic length of the support rod 27. In at least one implementation, through holes are provided at both ends of the telescopic rod, and support feet 32 ​​are threaded onto the through holes. The support feet 32 ​​are set in contact with the ground and together with the longitudinal rods 25 on both sides, they support the maintenance bracket and play a role in providing stable support for the maintenance bracket.

[0022] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
