[0021] In this embodiment, the limiting clamping mechanism includes a plurality of guide rods 7 fixedly connected to the inside of the movable seat 1, a support plate 9 fixedly connected to the outer side of the guide rod 7, two limiting blocks 8 slidably connected to the outer side of the guide rod 7, and a protective pad 15 fixedly connected to the bottom of the support plate 9 and the opposite side of the two limiting blocks 8, so as to conveniently use the protective pad 15 to prevent damage to the electrical equipment during the process of clamping the electrical equipment. The two limiting blocks 8 are symmetrically arranged on the movable seat 1.

[0022] Among them, an adjustment component for adjusting the position of the limit block 8 is arranged inside the movable seat 1, and the adjustment component includes a clamping motor 5 fixedly connected to the right side of the movable seat 1, and the output end of the clamping motor 5 is fixedly connected to a bidirectional screw 6 threadedly connected to the limit block 8, so that the limit block 8 can move to the side that is away or close to it as the bidirectional screw 6 rotates.

[0023] In this embodiment, the interior of the limit block 8 is fixedly connected to an electric push rod 10, and the output end of the electric push rod 10 is fixedly connected to a movable block 11, so that the position of the movable block 11 can be adjusted conveniently by using the electric push rod 10. The interior of the movable block 11 is slidably connected to a limit base plate 12, and the front and rear sides and the top of the limit base plate 12 are fixedly connected to a limit slider 1202. A limit slot that is slidably matched with the limit slider 1202 and the limit base plate 12 is provided inside the movable block 11, so that the limit slider 1202 can be used conveniently to improve the activity stability of the limit base plate 12.

[0024] Among them, a moving component for adjusting the position of the limiting base plate 12 is arranged inside the movable block 11, and the moving component includes a transmission rack 1201 fixedly connected to the top of the limiting base plate 12, and a shift motor 13 is fixedly connected inside the movable block 11, and the output end of the shift motor 13 is fixedly connected to a transmission gear 14 meshing with the transmission rack 1201, so that the shift motor 13 can drive the limiting base plate 12 to move by utilizing the transmission action of the transmission rack 1201 and the transmission gear 14.

[0025] In this embodiment, the top of the movable seat 1 is fixedly connected with a lifting assembly for connecting to the lifting equipment. The lifting assembly includes a connecting frame 2 fixedly connected to the top of the movable seat 1. The top of the connecting frame 2 is detachably connected with a lifting rope 3. The lifting rope 3 is installed on the lifting equipment, so that the lifting equipment can easily adjust the lifting of the movable seat 1 by winding up the lifting rope 3.

[0026] The beneficial effects of the above embodiments are:

[0027] This lifting equipment for the construction of large-scale power equipment can adjust the position of the limiting base plate 12 by operating the electric push rod 10 after the movable seat 1 is moved to the top of the power equipment, so that the distance between the limiting base plate 12 and the abutment plate 9 can adapt to the height of the power equipment. After that, the movable component can be used to extend the limiting base plate 12 to the bottom of the power equipment to achieve the function of lifting the power equipment.

[0028] The working principle of the above embodiment is:

[0029] The lifting device for large-scale power equipment construction can realize the lifting and lowering adjustment of the movable seat 1 by winding up the lifting rope 3. When the power equipment needs to be lifted, the movable seat 1 needs to be moved to the top of the power equipment first, and the position of the limiting bottom plate 12 needs to be adjusted by operating the electric push rod 10, so that the distance between the limiting bottom plate 12 and the abutment plate 9 can be adapted to the height of the power equipment, and then the shifting motor 13 can be operated to make the shifting motor 13 drive the limiting bottom plate 12 to move by the transmission action of the transmission rack 1201 and the transmission gear 14, so as to facilitate the extension of the limiting bottom plate 12 to the bottom of the power equipment;

[0030] Afterwards, the clamping motor 5 can be operated to drive the bidirectional screw 6 to rotate, and the limit block 8 can move to the side that is separated or close to each other as the bidirectional screw 6 rotates, so as to facilitate the two limit blocks 8 to move closer to each other to clamp the power equipment. At this time, the electric push rod 10 can be retracted to make the limit base plate 12 lift the power equipment, so that the top of the power equipment fits against the plate 9, thereby limiting the movement of the power equipment during the lifting process, playing an anti-falling effect, improving the safety of the power equipment during the lifting process, and effectively improving the practical effect of the device.
