Problems solved by technology

The disadvantage of this structure is: due to the large volume of the capacitor, it is difficult to ensure the safety during the lifting process using the traditional hoist
The disadvantage of this structure is that there is no image monitoring of the equipment that needs to be lifted during the lifting process, so there is a visual blind spot when working at heights

Embodiment 1

[0038] like figure 2 As shown, the present invention includes a hoisting mechanism, a transfer mechanism and a control system, wherein,

[0039] The hoisting mechanism includes a fixed base, a support rod 2 and an upper arm 3, and the fixed base includes a fixed plate 4, a fastener 5 for fixing the fixed plate 4 and the serial compensation platform 1, and an adapter for connecting the support rod 2 6. Fasteners 5 use bolts, adapters 6 are bearings welded to the upper end surface of fixed plate 4, ribs 7 are welded between adapters 6 and fixed plate 4, and the lower end of support rod 2 and adapter 6 The inner ring (not shown in the figure) is fixedly connected, the upper end of the support rod 2 is hinged with one end of the upper support arm 3, and a fastening bolt 8 is set at the connection between the support rod 2 and the upper support arm 3, and the upper support arm 3 is hydraulically telescopic Cylinder and welding limit ring 9 on its upper end face;

[0040] like ...

Embodiment 2

[0043] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is: as Figure 5 As shown, the free end of the traction rope 20 is also provided with a clamping device. The clamping device includes two groove-shaped clips 28 arranged symmetrically. One end of the groove-shaped clip 28 is provided with a semi-ring guard plate 29. A limiting protrusion 30 is arranged in the groove at the other end of the body 28, and the two groove-shaped clamping bodies 28 are fixed by bolts.

Embodiment 3

[0045] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is: as Image 6 As shown, when the series compensation platform 1 is a grid structure, the first through hole (not shown in the figure) is set on the fixed plate 4, the fixing bolt 31 is set through the first through hole, the fastener 5 is an M-shaped plate, and the M The shape plate is installed between the fixed plate 4 and the series compensation platform 1 and is provided with a second through hole (not shown in the figure). After the fixing bolt 31 passes through the first through hole and the second through hole, a nut 32 is installed. The nut 32 is located at the The lower end face of platform 1.

Description

technical field [0001] The invention belongs to the technical field of power equipment maintenance, in particular to a portable emergency repair device for hoisting ultra-high voltage series compensation platform equipment. Background technique [0002] The series capacitance compensation technology is to connect a capacitor bank in series in the transmission line, and use the capacitive reactance of the capacitor to offset the inductive reactance of part of the transmission line, thereby reducing the equivalent reactance of the line. On high-voltage long-distance transmission lines, it is equivalent to shortening the electrical distance, thereby improving the stability limit and transmission capacity of the line. [0003] The height of the UHV series compensation platform is 13 meters (such as figure 1 shown) is used for the first time in China. The platform includes capacitors, MOVs, dampers, GAPs, etc. The equipment parts are densely populated and have a high failure rat...
