Abstract
The utility model discloses a spanning frame for aerial power lines, comprising an insulating ladder. The insulating ladder is of a telescopic structure, and equipped with a transverse supporting rod in the top, wherein inclined supporting rods are arranged between the transverse supporting rod and the insulating ladder; coiling devices are arranged on the transverse supporting rod, wherein each coiling device comprises an idle gear rack, an idle gear and a movable hasp; the movable hasp is arc-shaped, wherein one side of the movable hasp is hinged to one side in the upper end of the idle gear rack, and the other side of the movable hasp is movably connected with the other side in the upper end of the idle gear rack; and wear-resistant sheaths are arranged in the lower end portions of the insulating ladder. The spanning frame for aerial power lines is simple in structure and convenient in use; can adjust the height of the ladder at any time according to practical construction requirements; can obviously reduce the cost of line construction; and ensures efficiency of power line construction.
Description
Technical field:
The utility model relates to a kind of spanning equipment of transmission line, particularly relates to a kind of power circuit overhead wire crossing frame.
Background technology:
In the erection construction process of power circuit overhead wire, high-tension power circuit often needs to cross over power overhead network, communication line, lightguide cable link and other barriers of low-voltage, and when crossing over generation, usually need to build interim crossing frame, but because crossover point is more, when lower the and spacing of the relative ground distance of circuit of crossing over when needs is narrower, if build equally the interim crossing frame bothersome effort again of taking a lot of work that just seems, the construction investment that not only increases circuit also can extend construction period.
The utility model content:
Technical problem to be solved in the utility model is: provide a kind of cost power circuit overhead wire crossing frame lower, easy to use.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of power circuit overhead wire crossing frame, comprise insulating ladder, and described insulating ladder is the extension type structure, and top is provided with support rail, between described support rail and insulating ladder, is provided with knighthead; Be provided with Winder on described support rail.
Described Winder comprised wheel carrier, third wheel and movable hasp; Described movable hasp is circular shape, on one side with to cross wheel carrier upper end one side hinged, another side with cross wheel carrier upper end opposite side and be flexibly connected.
Described insulating ladder bottom is provided with wear-resistance protective sleeve.
During use, the utility model, near needing the object of crossing over, is opened to movable hasp, cable is passed from third wheel, buckle movable hasp, make cable stride across the object that need to be crossed over and get final product.
Positive beneficial effect of the present utility model is as follows:
Insulating ladder of the present utility model is the extension type structure, can need to adjust at any time the ladder height according to practice of construction, economic and practical.
The utility model is simple in structure, easy to use, can obviously reduce construction of line construction cost, the efficiency of construction that provides power circuit to set up.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further described:
Referring to Fig. 1, a kind of power circuit overhead wire crossing frame, comprise insulating ladder 6, wherein, insulating ladder 6 is the extension type structure, and its top is provided with support rail 4, between support rail 4 and insulating ladder 6, is provided with knighthead 5, be provided with Winder on support rail 5, Winder comprised wheel carrier, 1, third wheel 2 and movable hasp 3, and movable hasp 3 is circular shape, on one side with to cross wheel carrier 1 upper end one side hinged, another side with cross wheel carrier 1 upper end opposite side and be flexibly connected.Be provided with wear-resistance protective sleeve 7 in described insulating ladder 6 bottoms.
This utility model is simple in structure, easy to use, can need to adjust at any time the ladder height according to practice of construction, can obviously reduce the construction cost of the construction of line, the efficiency of construction that provides power circuit to set up.
