[0040] In some embodiments, the support frame 2 comprises a rotating support frame 2-1, a door-shaped support frame 2-2, and a hanging frame 2-3. The rotating support frame 2-1 is rotatably connected to the top edge of the moving frame 1 (i.e., rotatably connected to the top of the partial vertical rod 1-3), and the rotating axis is parallel to the horizontal plane. The rotating support frame 2-1 can be rotated to touch the top of the moving frame 1 (i.e., rotated to touch the top of the remaining vertical rod 1-3). The door-shaped support frame 2-2 is detachably connected to the side and top edge of the moving frame 1 (the top edge is the top of the remaining vertical rod 1-3 which is not rotatably connected to the rotating support frame 2-1). The hanging frame 2-3 is detachably connected to the rotating support frame 2-1 and the door-shaped support frame 2-2, and the hanging frame 2-3 can be simultaneously assembled between the rotating support frame 2-1 and the door-shaped support frame 2-2.

[0041] As preferred, the rotating support frame 2-1 is substantially in the shape of a door-shaped support frame 2-2, which is mainly connected by three connecting rods, and two of the connecting rods in the rotating support frame 2-1 are rotatably connected to two vertical rods 1-3 in the moving frame 1.

[0048] It should be noted that, Figure 2 The folding scheme shown is only a preferred scheme. In other embodiments, when the support frame 2 needs to be folded, the door-shaped support frame 2-2 in the support frame 2 can also be installed in other parts of the moving frame 1 in an upright or horizontal posture through connecting members such as bolts. Even in some embodiments, after the rotating support frame 2-1 is turned to touch the top of the moving frame 1, the door-shaped support frame 2-2 is horizontally installed on the upper surface of the rotating support frame 2-1. That is, the installation position of the door-shaped support frame 2-2 in the folded state can be variously selected, as long as it can realize the small footprint storage and placement of the door-shaped support frame 2-2.

[0049] Further, as Figure 3 As shown, the hanging basket structure 3 includes a tray 3-1, and the support surface of the tray 3-1 is provided with a rolling support 3-2, which includes but is not limited to a bull eye bearing, to facilitate the horizontal sliding of the electrical appliances 4.

[0054] Further, vertical sliding rails can also be arranged in the rotating support frame 2-1 and the door-shaped support frame 2-2, so that the hanging basket structure 3 can be stably lifted into the support frame 2 when the subsequent lifting adjustment of the hanging basket structure 3 is carried out.

[0055] Further, the circumferential side of the connecting rod 3-5 is vertically spaced with multiple connecting nodes 3-5a, and the lifting frame 3-4 can be connected at any connecting node 3-5a of the connecting rod 3-5. This makes the distance between the lifting frame 3-4 and the tray 3-1 flexible, and the overall height of the basket structure 3 can be adjusted to adapt to the size of the electrical device 4 and the article to be lifted.

[0056] As preferred, a bolt hole is provided at the connecting node 3-5a, and the detachable connection of the lifting frame 3-4 and the connecting rod 3-5 is realized by assembling a bolt and a nut at the bolt hole.

[0060] Further, the main body material of the device is made of profiled square steel material welded and spliced, and the overall structure is simple and the manufacturing cost is low. In addition, under the design scheme, the structures and frames of the present scheme are modularized, and the modules are connected by pins or bolts, which are easy to disassemble and assemble.

[0061] As described above, when the device is used for disassembling and assembling the electrical device 4, the device can be first adjusted to the tool frame state as shown in Figure 1 , the electrical device 4 is placed on the tray 3-1 of the basket structure 3, and the traction rope is driven to move the tray 3-1 assembly to realize lifting, and the electrical device 4 is pushed into the equipment installation position when it is lifted to the appropriate position.

[0062] Under the design, the device can be used to assist in disassembling large weight devices, eliminating the safety risks existing when only using manpower to disassemble and assemble, and reducing the physical consumption of the test personnel.
