Insulator string pushing terminal

Abstract

The invention provides an insulator string pushing terminal. The insulator string pushing terminal comprises a base, a shell installed on the base, a first grasping arm, a second grasping arm and two connecting rods, wherein the shell is T-shaped and comprises a longitudinal extension portion and a horizontal extension portion, a screw-nut structure is arranged in the longitudinal extension portion, and a nut of the screw-nut structure extends out from the front part of the shell; the first grasping arm and the second grasping arm are pivotally connected with two ends of the horizontal extension portion of the shell respectively; and the two connecting rods are pivotally connected to the middle parts of the first grasping arm and the second grasping arm and the nut of the screw-nut structure. According to the invention, a motor drives a screw to rotate, the nut is driven to move along the longitudinal direction, and the connecting rods are driven so as to enable the first grasping arm and the second grasping arm to be folded or separated. The insulator string pushing terminal provided by the invention is simple in structure, stable in operation and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of high-voltage transmission line maintenance, in particular, the invention relates to an insulator string pushing end of a live-operating robot for a high-voltage transmission line. Background technique [0002] After the electric energy is generated in the power plant, it needs to be transmitted to various places through high-voltage transmission lines, so high-voltage transmission lines are everywhere, including cities, rural areas and so on. High-voltage transmission lines generally refer to lines with a voltage of 220V or above. The maintenance and maintenance of high-voltage transmission lines are subject to various restrictions. First, because the lines are electrified, there are potential safety hazards in direct manual operation. The environment or topography may have high-voltage transmission lines that are difficult or impossible for workers to touch or approach. Therefore, there is a demand for a...

High-voltage transmission lines generally refer to lines with a voltage of 220V or above. The maintenance and maintenance of high-voltage transmission lines are subject to various restrictions. First, because the lines are electrified, there are potential safety hazards in direct manual operation. The environment or topography may have high-voltage transmission lines that are difficult or impossible for workers to touch or approach. Therefore, there is a demand for automatic maintenance or maintenance or repair devices for high-voltage transmission lines, and high-voltage transmission line robots emerge as the times require.

[0003] The existing high-voltage transmission line robots are usually used for high-voltage line inspections. Although they can replace manual inspections and have the advantages of stable operation quality and high efficiency, they cannot perform basic maintenance operations, such as insulator string replacement, durable Tension clamp bolt fastening and other work, these work also need manual live operation, there is a big potential safety hazard
