High-voltage transmission line linear tower electrified operation overhead ground wire lifting device

Abstract

The invention discloses a high-voltage transmission line linear tower electrified operation overhead ground wire lifting device comprising a main plate, clamping plates, a pressing plate and lifting screws. Two sides of the main plate are provided with symmetrical left and right elongated bolt grooves, the clamping plates are inverted triangle plates, and left and right inverted triangle plates are arranged at the bottom of the main board corresponding to the left and right elongated bolt grooves and are connected to the main plate through the left and right bolts in the left and right elongated bolt grooves and corresponded screwed nuts; the pressing plate is arranged below the main plate, is lower than the left and right inverted triangle plates and is middle between the left and right inverted triangle plates, and the pressing plate is connected to the main plate through left and right pressing screws in the left and right elongated bolt grooves and corresponded screwed nuts; the upper ends of the left and right lifting screws are screwed with left and right screwed sleeves of the main plate through left and right through holes, and the lower ends of the left and right screws are provided with hanging rings. The device is light and convenient to carry, can be operated by one person and is capable of operating in an electrified manner, the operating time of an operator is reduced, and the operating efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of power line maintenance equipment, in particular to a lifting device for an overhead ground wire for live work on a straight line iron tower of a high-voltage transmission line. Background technique [0002] In view of the ever-increasing overhaul of overhead ground wires of linear pole towers on high-voltage lines, such as suspension point displacement, suspension clamp replacement, ground wire repair, etc., the commonly used method is to use tools such as pulleys, hand hoists, and wire rope heads to perform steering operations. Complete the lifting of the overhead ground wire. This ordinary method is inefficient, requires a lot of tools and tools, and the lifting force is often turned, the fixing and binding are complicated and the safety risk is relatively large. Appropriate, the lifting of the overhead ground wire will shift, which may lead to repeated work, and greatly increase the staff's stay time ...

AI Technical Summary

Problems solved by technology

This ordinary method is inefficient, requires a lot of tools and tools, and the lifting force is often turned, the fixing and binding are complicated and the safety risk is relatively large. Appropriate, the lifting of the overhead ground wire will shift, which may lead to duplication of work, and greatly increase the staff's stay time on the tower. On average, it takes nearly one and a half hours for one job, and it also increases the safety hazards in the work

[0003] More importantly, with the requirement of social benefits to reduce the power outage time of the line, live work will become more frequent in future work. However, the tools used in the traditional method are long strip-shaped all-metal tools and have many hanging points. Therefore, it cannot meet the requirements of live work, so we are in urgent need of an overhead ground wire lifting device that can meet live work, is light and smart, and can adapt to most types of iron towers.
