[0006] Preferably, a worktable is slidably mounted on the upper side of the lifting frame, and a connecting seat is fixedly mounted on the lower surface of the worktable. A threaded hole is opened on the side of the connecting seat, and a connecting bolt is inserted into the side of the second movable plate. The threaded end of the connecting bolt can be threaded into the threaded hole of the connecting seat. Multiple first rollers and multiple second rollers are rotatably mounted on both sides of the lifting frame. A sliding groove is opened on the lower side of the worktable. The first rollers and second rollers roll along the inner wall of the sliding groove. The worktable can move horizontally together with the second movable plate, so that the center of gravity of the worktable is always on the upper side of the scissor brace assembly, improving stability under load.

[0007] Preferably, a rotating platform is rotatably mounted on the upper surface of the workbench, and a plane bearing is provided between the workbench and the rotating platform.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a support frame for electrical equipment maintenance, including a base 1 and a lifting frame 2. A drive cylinder 3 is rotatably mounted on the upper surface of the base 1, a first movable plate 4 is slidably mounted on the upper surface of the base 1, a second movable plate 5 is slidably mounted on the lower side of the lifting frame 2, and a scissor brace assembly is provided between the base 1 and the lifting frame 2. The scissor brace assembly includes a first inclined plate 6 and a second inclined plate 7, which are rotatably connected. The bottom end of the first inclined plate 6 is rotatably connected to the base 1, the top end of the first inclined plate 6 is rotatably connected to the second movable plate 5, the bottom end of the second inclined plate 7 is rotatably connected to the first movable plate 4, the top end of the second inclined plate 7 is rotatably connected to the lifting frame 2, and the telescopic end of the drive cylinder 3 is fixedly connected to the first movable plate 4.

[0021] Specifically, two sets of first guide rails 15 are fixedly installed on the upper surface of the base 1. The two ends of the first movable plate 4 are slidably connected to the two sets of first guide rails 15 respectively. Two sets of second guide rails 16 are fixedly installed inside the lifting frame 2. The two ends of the second movable plate 5 are slidably connected to the two sets of second guide rails 16 respectively. When the first movable plate 4 is horizontally pushed and pulled by the extension and retraction of the drive cylinder 3, the included angle between the first inclined support plate 6 and the second inclined support plate 7 changes, thereby lifting or lowering the lifting frame 2.

[0022] A workbench 8 is slidably mounted on the upper side of the lifting frame 2. A connecting seat 9 is fixedly mounted on the lower surface of the workbench 8. A threaded hole is opened on the side of the connecting seat 9. A connecting bolt 10 is inserted into the side of the second movable plate 5. The threaded end of the connecting bolt 10 can be threaded into the threaded hole of the connecting seat 9.

[0023] The lifting frame 2 has multiple first rollers 13 and multiple second rollers 14 rotatably mounted on both sides. The worktable 8 has a sliding groove on its lower side, and the first rollers 13 and second rollers 14 roll along the inner wall of the sliding groove.

[0024] It should be noted that when the scissor bracing assembly lifts the lifting frame 2, the distance between the bottom and top ends of the first diagonal brace plate 6 and the second diagonal brace plate 7 both decrease, reducing the stress area and making it prone to instability. By setting a sliding worktable 8 on the lifting frame 2 and connecting the second movable plate 5 to the connecting seat 9 on the lower side of the worktable 8 using connecting bolts 10, the worktable 8 moves horizontally along with the second movable plate 5 during the lifting process of the lifting frame 2, ensuring that the center of gravity of the worktable 8 is always on the upper side of the scissor bracing assembly, greatly improving the lifting stability of the support frame and making it safer to use.

[0025] A rotating platform 11 is rotatably mounted on the upper surface of the workbench 8, and a plane bearing 12 is provided between the workbench 8 and the rotating platform 11. The maintenance equipment is placed on the rotating platform 11 and can rotate together with the rotating platform 11, making it easy to adjust its angle and providing convenience for maintenance.

[0026] Four support legs 17 are threadedly installed on the lower surface of the base 1. The four support legs 17 are respectively arranged at the four corners of the base 1. Multiple casters 18 are fixedly installed on the lower surface of the base 1. The casters 18 roll on the ground to facilitate the movement of the device. When the device reaches its destination, the support legs 17 are screwed down and put into contact with the ground, making the base 1 more stable.

[0027] This electrical equipment maintenance support frame uses a scissor brace assembly between the base 1 and the lifting frame 2. The scissor brace assembly is driven by the drive cylinder 3, which enables the lifting frame 2 to move up and down. This not only gives the lifting frame 2 a higher lifting height, but also allows it to fall to a lower position, resulting in a lower initial height for the support frame. This makes it more convenient to use and meets the needs of maintenance work at different heights.

[0028] Working principle: During use, the retraction of the extension end of the drive cylinder 3 causes the first movable plate 4 to slide along the first guide rail 15. At this time, the bottom and top distances of the first inclined support plate 6 and the second inclined support plate 7 decrease. The first and second inclined support plates 6 and 7 flip up, lifting the lifting frame 2 so that the maintenance equipment can be supported by the lifting frame 2. When the extension end of the drive cylinder 3 extends, it pushes the first movable plate 4 away from the drive cylinder 3 and moves horizontally. At this time, the bottom and top distances of the first and second inclined support plates 6 and 7 increase. The first and second inclined support plates 6 and 7 can be flipped and folded together, reducing the height of the lifting frame 2. This design allows the lifting frame 2 to descend to a lower height, so that the support frame can be placed in the gap under the equipment to be maintained, so as to lift the maintenance equipment for maintenance work.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
