It can complete tasks sequentially, with high precision and quality, according to a programmed sequence. It improves production efficiency and ensures product quality. While obeying management commands, it reduces manual labor intensity and safety risks. However, industrial robots require a maintenance rack during operation.

[0003] The lifting-type industrial robot maintenance rack is an adjustable support device specifically designed for industrial robot maintenance. It consists of a high-strength steel frame, a hydraulic or electric lifting system, a non-slip work platform, and a movable base. Its core function is to achieve precise lifting of the platform through hydraulic cylinders, electric push rods, or lead screw mechanisms, adapting to the maintenance needs of robots at different heights. The work platform is equipped with guardrails, safety locks, and tool hooks to ensure safe and convenient operation; the bottom casters with locking devices facilitate movement and fixation.

[0004] Typical issues with the space adaptability of repair racks include the large space occupied by fixed supports, the need for height adjustment of accessories, and limited adaptability to multiple scenarios. At the same time, the fixed platform provides limited space for robot movement, which leads to the need for frequent movement of the repair rack during operation, resulting in risks during the movement of the repair rack. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a lifting maintenance rack for industrial robots, which aims to improve the design problems of large space occupation and small space for robot movement provided by the fixed platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lifting maintenance frame for industrial robots includes a base, a lifting assembly at the top of the base, a fixed platform fixedly connected to the top of the lifting assembly, two connecting frames fixedly connected to both sides of the fixed platform, a support frame fixedly connected to the left side of the connecting frame, a support rod rotatably connected to the bottom of the support frame, a support rotating rod rotatably connected to the other end of the support rod, a driven rod fixedly connected to the other end of the support rotating rod, a fulcrum rod rotatably connected to the middle of the driven rod, an adjusting rod fixedly connected to one side of the driven rod, and an extension plate fixedly connected to the top of the adjusting rod.

[0008] As a further description of the above technical solution: the lifting assembly includes an active rod, the active rod being slidably connected to the inner wall of the base, two sliding rings being rotatably connected to the outside of the active rod, a fixed plate being fixedly connected to the top of the sliding rings, a hydraulic pump being fixedly connected to the top of the fixed plate, a sliding rod being rotatably connected to the top of the hydraulic pump, fixed rods being fixedly connected to both sides of the sliding rod, a thrust rod being fixedly connected to the bottom of the fixed rod, active plates being rotatably connected to both ends of the thrust rod, connecting rods being rotatably connected to the opposite sides of the two active plates, follower plates being fixedly connected to both ends of the connecting rod, follower rods being fixedly connected to the top of the follower plate, a fixed column being fixedly connected to the top of the two active plates, a connecting plate being rotatably connected to the outside of the fixed column, and the top of the connecting plate being fixedly connected to the bottom of the fixed platform;

[0009] As a further description of the above technical solution: the fulcrum rod is externally fixedly connected to the inner wall of the support frame;

[0010] As a further description of the above technical solution:

[0011] Both sides of the top end of the active rod are rotatably connected to an active plate fixing bracket, and the bottom of the active plate is fixedly connected to the top of the active plate fixing bracket.

[0012] As a further description of the above technical solution:

[0013] The connecting plate has sliding grooves on both sides, and one side of the follower rod is slidably connected to the inner wall of the sliding groove.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the extension plate is smoothly unfolded and locked by linking a multi-stage transmission rod system with a supporting swivel. The coordinated movement of the support frame and the driven rod ensures that the extension plate is vertically raised and lowered without deviation. The rotation of the fulcrum rod drives the adjusting rod to press down, forming a self-locking structure, which enhances the stability of the platform. This design is easy to operate and has a compact structure. It can quickly complete the fixing and unfolding of the extension plate. It is suitable for industrial maintenance and other scenarios. It has the advantages of smooth unfolding, reliable locking, and strong load-bearing capacity, which effectively improves work efficiency and safety.

[0022] 2. In this utility model, a multi-stage linkage system driven by a hydraulic pump is used to achieve precise height adjustment. The coordinated transmission of the sliding ring and the thrust rod makes the lifting process more stable and reliable. The linkage design of the follower plate and the fixed column enhances the structural rigidity and prevents deviation. The hydraulic control provides strong thrust to ensure stable lifting under heavy load. It is suitable for heavy-duty scenarios such as industrial robot maintenance. It has the advantages of high adjustment accuracy, strong load-bearing capacity and stable operation, which significantly improves the safety and efficiency of operation. Attached Figure Description

The function of the driven rod 21 can be realized by moving the adjusting rod 23 up and down.

[0032] refer to Figures 2 to 4The lifting assembly includes an active rod 2, which is externally slidably connected to the inner wall of the base 1. Two sliding rings 3 are rotatably connected to the outside of the active rod 2, allowing adjustment of the angle of the fixed plate 4. A fixed plate 4 is fixedly connected to the top of each sliding ring 3, and a hydraulic pump 5 is fixedly connected to the top of the fixed plate 4. The hydraulic pump 5 pushes a sliding rod 6, which is rotatably connected to the top of the hydraulic pump 5. Fixed rods 7 are fixedly connected to both sides of the sliding rod 6, allowing adjustment of the thrust rod 8. The thrust rod 8 is fixedly connected to the bottom of each fixed rod 7, allowing adjustment of the angle of the active plate 9. Both ends of the thrust rod 8 are rotatably connected... The base 1 is equipped with two active plates 9, each with a connecting rod 10 rotatably connected to the opposite side of each active plate 9. A follower plate fixing bracket is fixedly connected to both sides of the inner wall of the base 1. The bottom of the connecting rod 10 is rotatably connected to the top of the follower plate fixing bracket. Follower plates 11 are fixedly connected to both ends of the connecting rod 10. The active plates 9 and follower plates 11 can be used to adjust the fixed plate 4. A follower rod 12 is fixedly connected to the top of the follower plate 11. A fixing column 14 is fixedly connected to the top of each active plate 9. The follower rod 12 and fixing column 14 can be used to adjust the height of the fixed plate 4. A connecting plate 15 is rotatably connected to the outside of the fixing column 14. The connecting plate 15 can be used to fix the fixed platform 16.

[0033] Both sides of the connecting plate 15 are provided with sliding grooves 13, which allow the follower rod 12 to move back and forth. One side of the follower rod 12 is slidably connected to the inner wall of the sliding groove 13. The top of the connecting plate 15 is fixedly connected to the bottom of the fixed platform 16. Both sides of the top of the active rod 2 are rotatably connected to the active plate fixing bracket 25, which allows the active plate 9 to be adjusted. The bottom of the active plate 9 is fixedly connected to the top of the active plate fixing bracket 25. The lower side of the base 1 is fixedly connected to the tire fixing bracket 26, and the lower end of the tire fixing bracket 26 is provided with a sliding tire 27, which allows the sliding tire 27 to be fixed.

[0034] Working principle: When the height of the connecting plate 15 needs to be adjusted, the hydraulic pump 5 controls the active rod 2 to move back and forth. The movement of the active rod 2 drives the sliding ring 3 to rotate. At this time, the rotation of the sliding ring 3 will drive the fixed plate 4 to rotate at an angle. The hydraulic pump 5 can push the sliding rod 6 to move. At this time, the sliding rod 6 is fixedly connected to the fixed rod 7. Therefore, the fixed rod 7 will move when pushed by the hydraulic pump 5. The push of the fixed rod 7 will drive the thrust rod 8 to move. The movement of the thrust rod 8 controls the movement of the active plate 9. At this time, the active plate 9 is rotatably connected to the follower plate 11 through the connecting rod 10. Therefore, the follower plate 11 will rise when the active plate 9 rises. When the follower plate 11 rises, the fixed column 14 will rise. Finally, the height of the connecting plate 15 is increased by the rise of the fixed column 14, thereby increasing the height of the platform.

[0035] When it is necessary to fix and unfold the extension plate 24, the support rod 19 is moved up and down by lifting the support rotating rod 20. The support frame 18 moves up under the movement of the support rod 19. The upward movement of the support frame 18 causes the extension plate 24 to move up. The driven rod 21 moves up under the upward movement of the support rotating rod 20. The upward movement of the driven rod 21 causes the fulcrum rod 22 to rotate. Finally, the adjustment rod 23 moves down under the rotation of the fulcrum rod 22, thereby fixing and extending the extension plate 24.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
