Abstract
The utility model relates to a rolling bracket for a winding and unwinding line in a power transmission line, belonging to an auxiliary device for the winding and unwinding line in the power transmission line. The utility model aims at solving the technical problems that the existing spanning bracket is easy to hang and abrade the lead wires and has large traction resistance and high maintenance cost. The technical scheme of the utility model is: the rolling bracket for the winding and unwinding line in the power transmission line comprises a main frame and a supporting bracket which is arranged in the middle part of the main frame, wherein the rolling bracket further comprises a carrier roller and two vertical blocking rollers, the carrier roller is installed in the middle of the supporting bracket; the lower ends of the two vertical blocking rollers are mounted on the main frame and located at the two sides of the carrier roller. The rolling bracket is not easy to hang and abrade the lead wire, and the rolling bracket is high in lead wire transmission capacity, small in tractor load, low in maintenance cost, saved in energy and little in working intensity.
Description
Technical field
The utility model relates to a kind of transmission line and puts stringing with rolling frame, and it belongs to a kind of auxiliary equipment that transmission line is put stringing that is used for.
Background technology
In the transmission line installation process, the situation that lead is crossed over railway, highway, power circuit, communication line and various buildings happens occasionally, and especially in the mountain construction process, the lead span is bigger, brings a lot of inconvenience for workpeople's installment work.The tradition solution is to build a steel pipe crossing frame or China fir bridge, and lead is placed on the crossing frame, adopts hauling machine traction lead, this method to a certain extent solved the problems referred to above.But because crossing frame is a fixed structure, resistance is bigger, and lead easily blocks the extension accident in the process of advancing on the one hand, have potential safety hazard, lead also easy to wear makes smooth lead become coarse, even burr, reduced the transmittability of electric energy, easily cause the corona accident; Bigger on the other hand resistance has also increased the weight of the mechanical load of hauling machine, has increased maintenance cost, energy resource consumption and the working strength of workers of hauling machine.
Summary of the invention
The purpose of this utility model is to solve easy card hanging mill that existing crossing frame exists to decrease lead, tractive resistance is big, maintenance cost is high technical problem, provides a kind of and does not block extension, the lead that do not wear and tear, tractive resistance is little and maintenance cost is low transmission line put stringing with rolling frame.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be:
A kind of transmission line is put stringing with rolling frame, comprises body frame and the bracing frame that is contained in the body frame middle part, and wherein: it comprises that also idler pulley and two perpendicular retainings roll, and idler pulley is contained in the centre of bracing frame; The lower end that two perpendicular retainings roll is contained on the body frame and is positioned at the both sides of idler pulley.
Transverse blocking-rod is equipped with to prevent wire dropping in the upper end that described perpendicular retaining rolls.
Described idler pulley and perpendicular retaining roll and adopt the nylon insulating material to make.
Because the utility model has adopted technique scheme, rotatable idler pulley has been installed on the frame and perpendicular retaining rolls rolling, and idler pulley and perpendicular retaining roll and adopt the nylon insulating material to make, smooth surface, prevented the card extension accident in the lead distraction procedure, reduced tractive resistance, also prevented the wearing and tearing of crossing frame lead, improve the transmittability of lead, reduced the generation of corona accident; Rotatable idler pulley has also alleviated the load of hauling machine simultaneously, has reduced maintenance cost, has saved the energy, has alleviated working strength of workers.If in the mountain area operation, also can roll on end transverse blocking-rod is installed at perpendicular retaining, prevent from that lead breaks away to roll frame, improved the fail safe of work.Therefore, compared with prior art, the utlity model has do not block extension, the lead that do not wear and tear, lead transmittability height, the hauling machine load is little, maintenance cost is low, save the energy and the little advantage of labor strength.
