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] Such as figure 2 As shown, the present invention includes a hoisting mechanism, a transfer mechanism and a control system, among which,

[0039] The hoisting mechanism includes a fixed base, a supporting rod 2 and an upper arm 3. The fixed base includes a fixed plate 4, a fastener 5 for fixing the fixed plate 4 and the series compensation platform 1, and an adapter for connecting the supporting rod 2 6. The fastener 5 uses bolts. The adapter 6 is a bearing welded on the upper end surface of the fixing plate 4, and the reinforcing rib 7 is welded between the adapter 6 and the fixing plate 4. The lower end of the support rod 2 and the adapter 6 The inner ring (not shown) is fixedly connected, the upper end of the support rod 2 is hinged with one end of the upper arm 3, and a fastening bolt 8 is set at the connection between the support rod 2 and the upper arm 3, and the upper arm 3 is hydraulically telescopic The cylinder is welded with a limit ring 9 on its upper end surfa...

Embodiment 2

[0043] The structure of this embodiment is basically the same as that of the first embodiment, the difference is: 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 clamp bodies 28 arranged symmetrically. One end of the groove-shaped clamp body 28 is provided with a semi-annular guard plate 29, and the groove-shaped clamp A limiting protrusion 30 is arranged in the groove at the other end of the body 28, and the two groove-shaped clip bodies 28 are fixed by bolts.

Embodiment 3

[0045] The structure of this embodiment is basically the same as that of the first embodiment, the difference is: Image 6 As shown, when the series compensation platform 1 is a grid structure, the fixing plate 4 is provided with a first through hole (not shown in the figure), and a fixing bolt 31 is inserted through the first through hole. The fastener 5 is an M-shaped plate. The shaped plate is installed between the fixed plate 4 and the series compensation platform 1 and is provided with a second through hole (not shown). The fixing bolt 31 penetrates the first through hole and the second through hole and then a nut 32 is provided. The nut 32 is located in the series compensation platform. The bottom 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 UHV series compensation platform equipment. Background technique [0002] The series capacitance compensation technology is to string a capacitor bank in the transmission line, and use the capacitive reactance of the capacitor to offset part of the inductance of the transmission line, thereby reducing the equivalent reactance of the line. On the high-voltage long-distance transmission line, it is equivalent to shortening the electrical Distance, thereby improving the stability limit and transmission capacity of the line. [0003] The UHV series compensation platform is 13 meters high (such as figure 1 Shown) Used for the first time in China. The platform includes capacitors, MOVs, damping, GAP, etc. The equipment components are dense and the failure rate is high. The manufacturer only has a human-shaped ladder. Due to t...
