[0036] The lifting assembly 300 includes a placement slot 301 opened in the fixed rod 101, a rack 302 slidably installed in the placement slot 301, a rectangular plate 303 fixedly installed on the fixed rod 101, and a rotating member 304 arranged on the rectangular plate 303, through which the overall height of the device can be adjusted.

[0037] Specifically, the hanging component 107 includes a servo motor 107a fixedly mounted on one of the mounting plates 106, a forward and reverse screw rod 107b symmetrically and rotationally mounted on the mounting plate 106, a first belt 107c arranged between the two forward and reverse screw rods 107b, a movable frame 107d symmetrically and threadedly mounted on the forward and reverse screw rods 107b through the first belt 107c, a winding wheel 107e and a motor 107f arranged on the movable frame 107d, a rope 107g rotatably mounted on the movable frame 107d and wound around the winding wheel 107e, and a counterweight block 107h and a hook 107i fixedly mounted on the rope 107g.

[0038] Furthermore, the output end of the servo motor 107a is fixedly connected to one end of one of the forward and reverse screw rods 107b, and one of the forward and reverse screw rods 107b is driven to rotate by the servo motor 107a. One end of the winding wheel 107e is fixedly connected to the output end of the motor 107f, and the winding wheel 107e is driven to rotate by the motor 107f. The counterweight block 107h is arranged at one end close to the hook 107i, and the weight of the hook 107i is increased by the counterweight block 107h.

After the hook 107i contacts the bottom end of the electrical cabinet, the motor 107f stops working, and the staff hooks the hook 107i with the bottom of the electrical cabinet, and then starts the motor 107f again, so that the motor 107f rotates in the opposite direction, and the rope 107g begins to be recovered, and the electrical cabinet is driven up by traction, thereby completing the lifting.

[0041] Example 2

[0042] Reference Figure 1 - Figure 4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that the limiting member 205 includes a slide groove 205a opened on one group of fixed rods 101, a limiting frame 205b and a first spring 205c arranged on the slide groove 205a, the limiting frame 205b is slidably installed on the slide groove 205a, a rotating rod 205d is rotatably installed on the limiting frame 205b, and a cross bar 205e is fixedly installed on this group of fixed rods 101.

[0043] Specifically, the first spring 205c is located between the limit frame 205b and the slide groove 205a, and the limit frame 205b can be reset through the first spring 205c. The shape of the rotating rod 205d is "L" shape. A groove is provided at the bottom end of the limit frame 205b. The size of the groove is consistent with the size of the first load-bearing plate 201 and the second load-bearing plate 202 after being combined, thereby fixing the first load-bearing plate 201 and the second load-bearing plate 202.

[0044] Furthermore, the lower pressing member 206 includes a pressing plate 206a and a second spring 206b disposed on the support rod 103, and the pressing plate 206a is sleeved on the support rod 103;

[0045] There are a plurality of second springs 206b.

[0046] Furthermore, the second spring 206b is fixedly installed between the pressure plate 206a and the cross plate 105, and is sleeved on the support rod 103. The top of the pressure plate 206a is connected to open a plurality of square grooves, which are arranged equidistantly, and the rope 107g is located between the square grooves.

[0047] The rest of the structure is the same as that of Example 1.

[0048] Operation process: After the electrical panel cabinet is lifted, the top of the electrical panel cabinet will contact the pressure plate 206a, and push the pressure plate 206a to squeeze the second spring 206b. Then the staff will pull the rotating rod 205d upward, so that the rotating rod 205d drives the limit frame 205b to rise, so that the groove at the bottom of the limit frame 205b no longer contacts the combined first load-bearing plate 201 and the second load-bearing plate 202, so that the top height of the rotating rod 205d is greater than the cross bar 205e. At this time, the rotating rod 205d is pulled upward. The cross bar 205e is rotated 90 degrees, so that the cross bar 205e limits the rotation rod 205d, and then the limit frame 205b is fixed at this height. Then the staff pulls the second load-bearing plate 202, and drives the first load-bearing plate 201 to unfold and form a plane through the hinge. At this time, the cylinders 203 at both ends of the second load-bearing plate 202 will be inserted into the round holes 204, thereby limiting the second load-bearing plate 202. At this time, the motor 107f works again, and the rope 107g is lowered through the winding wheel 107e, so that the motor 107f can work again. The gas panel cabinet descends, so that the bottom end of the electrical panel cabinet contacts the top of the first load-bearing plate 201 and the second load-bearing plate 202, and supports the electrical panel cabinet. At this time, the reaction force of the second spring 206b will also cause the pressure plate 206a to follow the decline. The electrical panel cabinet is fixed by the downward pressure and the support of the first load-bearing plate 201 and the second load-bearing plate 202, and the shaking is reduced during the movement. After the electrical panel cabinet is moved to a suitable position, the electrical panel cabinet is lifted again by the rope 107g and the hook 107i. , then lift the second load-bearing plate 202 so that the second load-bearing plate 202 and the first load-bearing plate 201 are folded again and placed vertically, and then reset the rotating rod 205d. At this time, the reaction force of the first spring 205c pushes the limit frame 205b to reset, so that the groove at the bottom of the limit frame 205b is again engaged with the combined second load-bearing plate 202 and the first load-bearing plate 201 to fix them, and then lower the electrical cabinet through the rope 107g and the hook 107i to complete the movement of the electrical cabinet.

[0051] Specifically, there are several connecting rods 304a, one of which has a length consistent with the horizontal plate 105, a turntable is installed at one end of the connecting rod 304a, a slot 304d is opened at the other end, the gear 304b is meshed with the rack 302, and the rack 302 is fixedly installed on the support rod 103.

[0052] The rest of the structure is the same as that of Example 2.

[0053] Operation process: When the height of the device needs to be adjusted, the matching connecting rod 304a is rotated by rotating the turntable, and the other connecting rods 304a are also rotated synchronously through the transmission of the second belt 304c and the third belt 304g, so that the gear 304b starts to rotate, and the rack 302 rises through meshing, thereby driving the support rod 103 to rise, so that the lifting component 100 can be adjusted to a suitable height for lifting work according to the usage scenario. At the same time, before lifting, the rotating shaft 304f can be pulled outward to separate the block 304e from the slot 304d, and then the third belt 304g can be disassembled, so that the device can be moved horizontally or vertically to the position of the electrical panel cabinet, thereby improving the usage scenario of the device, and then the block 304e is inserted into the slot 304d to complete the installation of the rotating shaft 304f, and then the height is adjusted.
