Abstract
The utility model discloses a draw gear for a live spanning rack. The draw gear comprises a double-layer pulley, a first haulage rope and a towing plate, wherein the towing plate is of an elongated isosceles triangle shape, connecting holes are respectively arranged in the three angles of the isosceles-triangle plate, the first haulage rope is connected with the top connecting hole of the isosceles-triangle plate, and the two bottom connecting holes of the isosceles-triangle plate are respectively connected with a bearing rope and a second haulage rope. The draw gear for the live spanning rack has the advantage including simple structure, convenient operation, short time and high efficiency.
Description
Technical field
The utility model relates to charged paying-off implement field in power circuit process of construction, relates in particular to a kind of live crossing frame draw-gear.
Background technology
In power circuit engineering construction, inevitably run into the power circuit that has some to be crossed over, the one, before stringing, first the power circuit of being crossed over is had a power failure, will cause a lot of potential safety hazards like this, and the personnel that use are more, not only inconvenience but also dangerous; The 2nd, there are some power circuits of being crossed over not have a power failure, necessary live across; Live crossing frame is used in power circuit engineering construction by more and more, two carrying ropes in live crossing frame connect earth anchor formation cableway by hanging on double-deck coaster under cross-arm respectively, on cableway, establish some glass reinforced plastic pipes, electric wire by frame passes through from glass reinforced plastic pipe, completes live across stringing.At present, carrying rope, pull rope are from double-deck coaster by being to draw respectively, and not only workload is large, and operation easier is large, and glass reinforced plastic pipe is when arrange on cableway, and position is not easy accurate location.
Summary of the invention
Not enough for solving prior art, the utility model aim to provide a kind of simple in structure, easy to operate, the time is short, efficiency is high, glass reinforced plastic pipe easy accurate live crossing frame draw-gear of location in position while arranging on cableway.
The utility model is achieved by the following technical solution: a kind of live crossing frame draw-gear, comprise double-deck coaster, the first pull rope, it is characterized in that: it also comprises towing plate, described towing plate is elongated shape isosceles triangle plate, the place, three angles of described isosceles triangle plate is provided with connecting hole, and the first described pull rope is connected with isosceles triangle wrench portion connecting hole, two of bottoms of isosceles triangle plate connecting holes respectively with carry restrict, the second pull rope is connected.
The first described pull rope and isosceles triangle wrench portion's connecting hole junction, two of bottoms of isosceles triangle plate connecting hole is connected with rotary connector with carrying rope, the second pull rope junction respectively.
The first described pull rope is the Di Nima rope of diameter 10mm, the Di Nima rope that carrying rope is diameter 22mm, and the second pull rope is the Di Nima rope of diameter 10mm.
A kind of live crossing frame of the utility model draw-gear use principle: utilize two of bottoms of isosceles triangle towing plate plate connecting hole is connected with carrying rope, the second pull rope respectively, carrying rope, the second pull rope are pulled simultaneously, reach effect easy to operate, that the time is short, efficiency is high.
The concrete using method of draw-gear for a kind of live crossing frame of the utility model: adopt a mode of two of leading to unfold bearing rope and the second pull rope by towing plate, in advance the first pull rope is passed to the lower block of double block, the first pull rope is connected with isosceles triangle plate traction head connecting hole, two of bottoms of isosceles triangle towing plate plate connecting hole is restricted with carrying respectively, the second pull rope connects, after towing plate is crossed double block, remove the upper pulley pivot pin of double block, take out upper pulley, utilization is carried line apparatus bearing rope is carried to upper pulley top, again load onto coaster, pine removes to carry line apparatus, bearing rope is dropped down onto on the upper pulley of double block, the continuous traction of the second pull rope drops down onto on the lower block of double block, continue to tract bearing rope and the second pull rope.
A kind of live crossing frame of the utility model band with draw-gear have advantages of simple in structure, easy to operate, the time is short, efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, each sequence number respectively: 1, double-deck coaster; 2, the first pull rope; 3, towing plate; 4, carrying rope; 5, the second pull rope.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
Referring to accompanying drawing 1, a kind of live crossing frame draw-gear, comprise double-deck coaster 1 first pull rope 2, it also comprises the towing plate 3 elongated shape isosceles triangle plates described in towing plate 3, the place, three angles of described isosceles triangle plate is provided with connecting hole, the first described pull rope 2 isosceles triangle wrench portion connecting holes connect, and two of bottoms of isosceles triangle plate connecting hole connects with carrying rope 4 second pull ropes 5 respectively; First described pull rope 2 isosceles triangle wrench portion's connecting hole junctions, two of bottoms of isosceles triangle plate connecting hole is connected with rotary connector with carrying rope 4 second pull rope 5 places of connecing respectively; The Di Nima rope of the first described pull rope 2 diameter 10mm, the Di Nima rope of carrying rope 4 diameter 22mm, the Di Nima rope of the second pull rope 5 diameter 10mm.
Embodiment is just for the ease of understanding the technical solution of the utility model; do not form the restriction to the utility model protection range; every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present utility model, above scheme being done that does not depart from technical solutions of the utility model, within all still belonging to the utility model protection range.
