Problems solved by technology

However, these devices are mostly used for high-voltage wiring. If they are used for low-voltage wiring in villages, they will look like big horses and small carts, and there are almost no trolleys and drones for wiring in rural areas.
In some rugged mountainous areas and poor mountain villages, it is even more unrealistic to use drones and trolleys; even if there is such equipment, it cannot be used due to the terrain; and the high cost of equipment cannot be afforded
Therefore, when wiring in rural areas, many people still use manpower to stretch the wires, and then fix them to the porcelain bottle on the cross arm. This kind of wiring not only wastes manpower, but also makes the sag of the wires not meet the national standard, and is prone to disconnection, etc. ACCIDENT

Abstract

The invention discloses a wire tightening device for low-voltage stringing and a stringing method, which relate to the technical field of stringing in a power system. The device comprises a wire pole part, a pole-mounting device part, a ground device part, a steel wire guiding rope and a power part. The wire tightening device is small in size, small in occupied space, easy to transport, and suitable for being used in harsh environment areas and plain areas. The device is simple to manufacture, and compared with a stringing vehicle and an unmanned stringing machine, the device is low in needed cost and little in maintenance cost. A drum is used for tightening the wire, the occupied area is narrowed in the case of construction, and the device is suitable for being used in a mountain area with a harsh environment. When the wire is light, the wire tightening device can tighten the wire via a crank; when the wire is long and heavy, a motor generates power for stretching the wire; and thus, manpower can be greatly reduced and the operation is more convenient and quicker. The DC motor is adopted as the power part, and the motor is quick to start, good in speed regulation performance and easy to control.

Description

technical field [0001] The invention relates to the technical field of stringing devices for electric power systems, in particular to a wire tightening device for low-voltage stringing. Background technique [0002] In recent years, with the continuous development of science and technology, various technologies of the power system continue to mature. At present, the wiring of power system lines has been developed to the high-tech level such as unmanned aerial vehicles and trolleys, saving time and effort. However, these devices are mostly used for high-voltage wiring. If they are used for low-voltage wiring in villages, they will look like big horses and small carts, and there are almost no trolleys and drones for wiring in rural areas. In some rugged mountainous areas and poor mountain villages, it is even more unrealistic to use drones and trolleys; even if there is such equipment, it cannot be used due to the terrain; and the high cost of equipment cannot be afforded.
