Problems solved by technology

According to the survey, grounding faults caused by the drop of overhead lightning wires caused by the wear of the suspension clamps occur from time to time. These faults are usually permanent accidents, which may cause tripping and power outages, or may burn the wires or lightning protection. line, which brings difficulties to the repair of the line and seriously threatens the security of the power grid
In the prior art, when replacing the suspension clamp of the overhead ground wire of the linear pole tower, usually multiple operators control the tension and angle to replace the suspension clamp, which is easy to cause damage to the equipment, and the construction safety is poor

Embodiment 1

[0021] Embodiment 1, a wire take-up device for a linear tower overhead line, including a pulley, a support mechanism, a support, a hook, a hook pulley and a control hinge, the support mechanism and the support are hinged and fixed, and the support mechanism includes a support body, two vertical The board and the angle adjustment unit, the two vertical boards are fixed vertically on the support body, the pulley is fixed between the two vertical boards through the pulley shaft, and the angle adjustment unit includes a hinged board body 1 and a hinged board body 2 respectively fixed to the support body. A number of hinged holes are arranged on the first hinged plate body and the second hinged plate body, and the support is fixed to the support mechanism through the hinged holes, and the support is fixed to the linear pole tower.

Embodiment 2

[0022] Embodiment two, see Figure 1~2 As shown, it is basically the same as Embodiment 1, the difference is that the first hinged plate and the second hinged plate are arranged parallel to each other, and several hinged holes are respectively arranged in a circular arrangement on the first hinged plate body and the second hinged plate body, and the adjustment of the tension angle is more convenient. Convenient, reliable, practical, see figure 2 As shown, with the cooperation of the hook and the hook pulley, the replacement of the suspension clamp can be completed under the adjustment and control of one operator. The pulley can choose U-shaped groove pulley or V-shaped groove pulley to adjust and control according to the use requirements. Due to the friction between the hinge and the pulley, the operator can adjust the tension and angle of the suspension line by controlling the hinge. The operation is more convenient and reliable. The tension of each suspension line is differ...

Abstract

The present invention relates to a suspension tower overhead line take-up device. The suspension tower overhead line take-up device comprises a pulley, a supporting mechanism, a support, a hook, a hook pulley and a control hinge, the supporting mechanism is hinged and fixed to the support and comprises a supporting body, two vertical plates and an angle adjusting unit, and the two vertical plates are fixed on the supporting body vertically. The pulley is fixed between the two vertical plates via a pulley shaft, and the angle adjusting unit comprises a hinging plate body 1 and a hinging plate body 2 which are fixed to the supporting body separately. The hinging plate body 1 and the hinging plate body 2 are both equipped with a plurality of hinging holes, and the support is fixed to the supporting mechanism via the hinging holes. The suspension tower overhead line take-up device of the present invention is simple in structure and reasonable in design, and enables the suspension clamps to be replaced under the cooperation of the hook and the hook pulley, namely under the regulation and control of a worker. The tension force of each suspension line is different and can be controlled by the angle adjusting unit, thereby being convenient to operate, relieving the labor intensity of the working personnel substantially, improving the safety of the construction working personnel, and being easy to popularize and implement.

Description

technical field [0001] The invention relates to the field of overhead ground wire equipment, in particular to a line take-up device for a straight pole tower overhead line with simple structure, reasonable design and good use effect. Background technique [0002] Overhead ground wires protect overhead transmission lines from lightning strikes, also known as lightning protection wires, or ground wires for short. The transmission line spans a vast area, and it is easy to be struck by lightning in the thunderstorm season, which will cause interruption of power transmission, which has become one of the main reasons for power outages in the power system. Installing overhead ground wires can reduce lightning accidents and improve the safety of line operation. The overhead ground wire is an important part of the high voltage transmission line structure. High-voltage and ultra-high-voltage substations occupy a large area and require a large area for direct lightning protection. It...
