Abstract
The utility model discloses a four-column bridge live work crossing rack. The main body of the four-column bridge live-wire work crossing rack is composed of four columns, four pairs of telescopic bridge arms, two carrying cables, two net sealing ropes, an insulation safety net, a spherical nest and a base, the four pairs of telescopic bridge arms on the four columns can be respectively assembled into two sets of door-type bridges after butted in the air. The carrying cable, the net sealing rope and the insulation safety net arranged between the bridges cause two sets of door-type bridges to be mutually connected to form the entirety of a four-column live crossing rack. The crossing rack solves the problem of crossing the 10 kv-330 kv live circuit in conductor developing construction and the ground line developing construction in the transmission engineering, and successfully realizes crossing the live circuit without power failure. The function of the utility model can be completely expanded to the degree of crossing the highway and the electrified railway.
Description
The utility model belongs to tools for live working, is specifically related to a kind of crossing frame of live line working.
Domestic existing crossing frame has twin columns composite type aluminium alloy crossing frame at present, there are the upright two groups of twin columns of group or three groups of twin columns aluminium alloy crossing frames in the job site, lay respectively at the unwrapping wire passage below of newly-built circuit, after binding with nylon wire in the crossing frame top, can come payingoff construction with tension stringing and manual stringing's method.The queen post crossing frame exists following deficiency: (1) sets up three-phase conducting wire needs three groups of queen post crossing frames, Work tool cost and construction cost height that span line needs; (2) can not charged or live line working fully; (3) in the unwrapping wire process as broken string, or accident conditions such as lead and drafting tool slippage can not guarantee that crossed line is perfectly safe.
Task of the present utility model is a kind of four-column bridge crossing frame of design, realizes not having a power failure crossing live-line when it can make power construction department payingoff construction.
For finishing above-mentioned task, the utility model has designed a kind of four-column bridge live across frame, and the main body of this crossing frame is made up of four root posts, the telescopic brachium pontis of fourth officer, insulation safety net, two ropeway carrying-ropes, two block ropes, ball cup 2 and bases 1.Its central post is made up of aluminium alloy epimere 29, hypomere 3, brachium pontis flange 7, goat's horn 26, aluminum alloy frame posture straightway 4, and stand is on ball cup 2 and base 1; Telescopic brachium pontis is made up of twisted wire wheel operation device 13, principal arm 14, telescopic arm 17, aerial docking facilities 18, and the twisted wire wheel operation device 13 of telescopic brachium pontis is twisted together with an end of brachium pontis flange 7; Brachium pontis flange 7 is between the aluminum alloy frame posture straightway 4 and aluminium alloy epimere 29 of column, and its opposite side and weight arm 5 are twisted together; Be furnished with ace's spanner 12 at twisted wire wheel operation device 13 coaxial ends, its other end has a ratchet 9; After docking, the telescopic brachium pontis of fourth officer on four root posts can be assembled into two groups of gate-type crane span structures respectively aloft, the ropeway carrying-rope 23 that is provided with between two groups of gate-type crane span structures, block rope 10 and insulation safety net 11 are implicative of each other two groups of gate-type crane span structures, form a four-column bridge live across frame integral body.
The difficult problem of the leap 10kv-330kv alive circuit that the utility model has run into when having solved spreading conducting wire, ground wire construction in the power transmission engineering has successfully realized the crossing live-line that do not have a power failure.Function of the present utility model can expand to acrossing highway, electric railway fully, brings huge economic benefit for sending power transformation construction unit and society.
Below in conjunction with accompanying drawing structure of the present utility model is described further:
Fig. 1 is the utility model overall structure schematic diagram.
As shown in Figure 1, four root posts of four-column bridge aluminium alloy crossing frame are made up of aluminium alloy epimere (29) and hypomere (3), brachium pontis flange (7), goat's horn (26), aluminum alloy frame posture straightway (4) respectively, each aluminum alloy frame posture straightway connects by bolt, stand is on ball cup (2) and base (1), by the backguy system firmly on the ground.The telescopic brachium pontis of fourth officer aluminium alloy is made up of twisted wire wheel operation device (13), principal arm (14), telescopic arm (17), aerial docking facilities (18) respectively, it is twisted together with brachium pontis flange (7) by wearing pin (8), fourth officer weight arm (5) is twisted together by wearing pin (6) with the opposite side of brachium pontis flange (7), and fixing by backguy (27).
Found four root posts according to the span size groups when erectting crossing frame, put down the telescopic brachium pontis of aluminium alloy, accomplish fluently backguy (24), cooperate with pawl assembly (9) with ace's wrench (12), twisted wire wheel operation device (13) drives backguy (15) by pulley (16) elongation, telescopic arm (17) skids off on roller (20), roating sphere headstock (2) when aloft docking, adjust backguy (24), (25), make two telescopic brachium pontis of aluminium alloy on same horizontal plane, guarantee aerial docking facilities (18) butt joint smoothly, then telescopic arm (17) locking is adjusted backguy (25) again, make it stressed evenly, at last telescopic arm (17) two ends are connected with nut, so just be assembled into two groups of gate-type crane span structures respectively.
After two groups of gate-type crane span structures are established, two ropeway carrying-ropes (23) are hung on the same column of two groups of gate-type crane span structures by manpower traction's mode, outer hoop assembly (28) through the column upper end is anchored on the default earth anchor, install cabling dolly (22) in the same way, its pulley (21) can be gone up evenly at ropeway carrying-rope (23) slide.Mode by the manpower traction again, block rope (10)) be anchored on the default earth anchor through the block coaster that is fixed on the column.By carrying the net coaster insulation safety net (11) is hung on the cable in the same way then, the operating personnel just can finish on the gate-type crane span structure safely and lay insulation safety net (11) this moment, the extradition pull line arrives by the crossing live-line sky, realize aerial live across, the escape way the when safety net that lays becomes stringing.
