Description
Technical Field
The invention relates to the field of power transmission line construction, in particular to a multi-layer modularized uninterrupted power supply crossing frame suitable for dense net sealing construction.
Background
With the increase of the voltage grade of the power transmission line, the increase of newly-built power transmission lines and the reduction of corridor resources of the power transmission lines, the newly-built lines inevitably need to cross the existing power transmission lines, railway tracks and the like. In order to ensure the construction safety, a crossing frame is usually erected above a crossed line and a protective net is installed to ensure the safety of the construction process of a newly-built line.
Currently, frame structures such as lifting type crossing frames, steel pipe crossing frames, self-lifting type crossing frames and lattice type crossing frames exist, but the frame structures are limited in the aspects of erection height, bearing capacity and the like, and short-time power failure is still needed when the crossing frames are erected and dismantled, so that the crossing frames are increasingly difficult to meet the requirements on stability, rapidity, convenience and protectiveness of the crossing frames during the cross-domain construction of ultra-high and extra-high voltage lines. Particularly, with the emergence of the requirement of dense net sealing spanning construction, the spanning frame is required to be capable of meeting the requirement of uninterrupted spanning of a plurality of lines with different spans.
Aiming at the problems, novel crossing frames are proposed in related institutions and construction units in recent years, for example, in a CN106655009A hydraulic lifting crossing frame, the height of a frame body can be increased through a hydraulic lifting device, the use of lifting equipment is avoided, and the requirement on construction rapidity is met to a certain extent. For example, in a patent CN 106368493a double-arm hydraulic propulsion type hard seal top lattice type crossing structure, a crossing arm is built in advance and integrally propelled by hydraulic pressure, but in order to ensure construction safety in the crossing mode, the length of the crossing arm is limited, and a long crossing arm is difficult to lift to a sufficient height after being assembled on the ground; when the crossing frame is assembled at high altitude, due to the lack of a reliable balancing device, in order to ensure the stability of the frame body and the construction safety, a base and an aerial work platform which are large enough and reliable enough must be designed, so that the crossing frame body is overstaffed, the difficulty of lifting the crossing frame is increased, and the requirement of uninterrupted crossing of a plurality of lines with different spans is difficult to adapt. Like patent CN107394678A telescopic boom block spanning frame adopts flexible arm structure, this kind of spanning frame easily installs and can realize not shutting off the block and stride across, but flexible arm structure adopts the design of multistage telescopic joint, and the telescopic joint is more flexible distance longer but flexible arm stability just is worse simultaneously, and reduce the telescopic joint and can improve stability but flexible distance will receive the restriction simultaneously, and the biggest span length is limited, is difficult to satisfy the requirement of crossing many transmission lines simultaneously under the intensive block spanning construction condition.
