Abstract
The invention relates to a portable electric power line spanning support. The portable electric power line spanning support comprises a vertical rod, a fixed pulley arranged at the upper portion of the vertical rod, and two stop rods which are arranged at two sides of the fixed pulley and are arranged in an inverted herringbone mode. The portable electric power line spanning support is characterized in that upper and lower end rod bodies of the vertical rod are respectively provided with a fixing ring, two ends of a binding rope are in movable connection with the two fixing rings. According to the portable electric power line spanning support, the ring wall of the vertical rod is additionally provided with the upper and lower fixing rings, so the vertical rod can be conveniently positioned at one side of a lower line through the binding rope, and the portable electric power line spanning support further has advantages of simple structure, convenient operation and strong practicality, moreover, the two stop rods are additionally provided with sleeves capable of realizing axial positioning and radial free rotation, so cable bounce does not occur in a wiring processing, even if cable bounce occurs, the cable can rapidly slide back to the fixed pulley, and the portable electric power line spanning support facilitates operators to carry out labor-saving time-saving wiring operation.
Description
Technical field
The present invention relates to a kind of electric power transmission line erection aid, especially belong to a kind of portable power circuit and cross over support.
Technical background
In erection electric power transmission line process; often can run into the problem of crossing over low voltage transmission line (namely rolling off the production line); for avoiding rolling off the production line generation friction in scissors crossing, cause mutual damage, before the present invention makes; usually two kinds of methods are had: one sets up crossing frame above rolling off the production line is introduced through and reaches the standard grade; this method cost of wasting time and energy is high, and two is on rolling off the production line, lay transition net, will reach the standard grade to be pulled through and roll off the production line; this method investment is little, but troublesome poeration is time-consuming.For this reason, occur in known technology that some plain types cross over the support rolled off the production line, these supports generally include a vertical rod, a fixed pulley is established in end thereon, during use, threw to roll off the production line by one of lead-in wire and to connect with cable, then, pulling goes between makes the lead-in wire be shelved on fixed pulley draw electric wire to cross and roll off the production line.But these supports exist following problems in actual use: vertical rod location structure is complicated, uses inconvenience, also there will be in extradition process and jump cable phenomenon.
Summary of the invention
For solving the problems of the technologies described above, the present invention aims to provide a kind of portable power circuit and crosses over support, and it is simple, easy to operate, practical that this support has structure, in extradition operation, there will not be the advantage of jumping cable phenomenon.
For achieving the above object, present invention employs following technical proposals: this portable power circuit crosses over support, comprise a vertical rod, and be arranged on the fixed pulley on this vertical rod top, two pins being positioned at these fixed pulley both sides, arranging in herringbone, it is characterized in that: on the shaft of described vertical rod upper and lower side, be respectively equipped with a retainer ring, the two ends of a tie are movable to be respectively connected on these two retainer rings.
During concrete enforcement, the shaft of described two pins is respectively equipped with an axial location, radial rotatable sleeve pipe.
During concrete enforcement, described two retainer rings are positioned on the upper-lower position of the same side ring wall of described vertical rod.
Beneficial effect: compared with prior art, after the present invention sets up retainer ring on the upper and lower ring wall of vertical rod, just can be positioned at vertical rod side of rolling off the production line easily by a tie, have the advantage that structure is simple, easy to operate and practical.In addition, after two pins are set up axial location, radial rotatable sleeve pipe, cable jumping phenomena would not be there is in lead-in wire process, even if there is jumping phenomena, cable also can slide to fixed pulley fast, contributes to that operating personnel is time saving and energy saving carries out lead-in wire operation.
Below in conjunction with accompanying drawing, by an embodiment, the invention will be further described.
Embodiment
See Fig. 1.This support comprises a vertical rod 1, and is arranged on the fixed pulley 2 on this vertical rod 1 top, two pins 3 being positioned at fixed pulley 2 both sides, arranging in herringbone.The shaft of described vertical rod 1 is respectively equipped with retainer ring 4 and lower retainer ring 6, connection part 7 represents that this vertical rod 1 can adopt multistage thread joined structure, with convenient working.The upper end of tie 5 can be fixed on upper retainer ring 4 through a knot that can be undone by a pull ring, and the lower end of tie 5 connects lower retainer ring 6 with colligation knot form.Two retainer rings are positioned at the same side of vertical rod 1, convenient operation.
The shaft of two pins 3 is set up axial location, radial rotatable sleeve pipe 31, contributes to that operating personnel is time saving and energy saving carries out lead-in wire operation.
During operation, first by this device horizontal in side of rolling off the production line, the free end of tie 5 was thrown the A that rolls off the production line, inflection is fastened on lower retainer ring 6, vertical vertical rod 1, makes its upper end rest on and rolls off the production line on A.Then, be introduced through one of pull rope the A that rolls off the production line, tie cable line 8, and make pull rope drop on the wheel face of fixed pulley 2, pulling traction rope can extradite cable 8.
Applicant states: above-described embodiment is only for explaining of the present invention opening one's minds, and any simple deformation structure of making by it inspires, all should include protection scope of the present invention in.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of one embodiment of the invention.
In figure: vertical rod 1, fixed pulley 2, pin 3, sleeve pipe 31, upper retainer ring 4, tie 5, lower retainer ring 6, connection part 7, cable 8(or deserve to be called line), roll off the production line A.
