Description

Technical Field

[0001] The present invention relates to the technical field of power grid equipment, and in particular to a parachute device on the top of a line supporting platform, which is used for achieving crossing over a span without power outage. Background Art

[0002] At present, it is difficult to implement the method of crossing transmission lines during power outages. The main types of existing transmission line crossings can be divided into: crossing power lines, crossing electrified railways, crossing navigable rivers and crossing highways. Common crossing frame construction methods include: (1) three-dimensional truss bamboo crossing frame; (2) fastener-type steel pipe crossing frame; (3) T-shaped (ram's horn) metal lattice crossing frame; (4) double-column combined suspension cable crossing frame; (5) tower-assisted cross-arm crossing frame.

[0003] Because there are many crossovers in the project line channel, high safety requirements and great construction difficulty, the traditional crossing frame construction always has various defects: for example, the bamboo frame has poor stability. When encountering typhoon weather, each bamboo must be checked repeatedly. In serious cases, the built frame must even be dismantled, otherwise there will be safety hazards. This will seriously delay the construction period, and all subsequent construction can only wait for the bamboo frame to be built. Moreover, building a bamboo frame requires a lot of manpower and time, and the height is limited, which may not meet the construction requirements. Moreover, the current crossing frames generally cannot achieve non-power-off crossing.

[0004] In the prior art, China's authorized patent announcement number: CN 105236277 A, discloses a fully automatic live net sealing vehicle and a net sealing method thereof, wherein the live net sealing vehicle includes a crane and a net sealing mechanism arranged on the top of the crane boom, wherein the net sealing mechanism includes a bracket, a scissor-fork telescopic arm, a cable, a net sealing, a hydraulic device, a hoisting device and a control device, wherein the bracket is fixedly mounted on the top of the crane boom, the scissor-fork telescopic arm is arranged on the side of the bracket, and the extension of the scissor-fork telescopic arm is controlled by the hydraulic device, one end of the cable is connected to the scissor-fork telescopic arm, and the other end is connected to the hoisting device, the net sealing is installed on the scissor-fork telescopic arm, and the control device is used to control the operation of the hydraulic device and the hoisting device. The fully automatic live net sealing vehicle and the net sealing method thereof described in the present invention use a crane as a carrier, can be moved and lifted by itself, and the retractable net sealing mechanism, the extension length of which can be set by itself according to requirements, has a small volume after folding, and is convenient to lift up and down.
