Fixtures for live replacement of UHV and EHV single-piece insulator robots

Abstract

This patent discloses a robot fixture for electrified replacement of UHV and UHV tensile single-piece insulators. Both the front card (3) and the rear card (1) include a main body (101) and an upper cover (102). A striker locking mechanism is provided between (102) and the main body (101); a motor locking mechanism (9) is provided at the threaded connection between the upper cover (102) and the main body (101). The motor (901) is electrically connected with the robot controller; the adjusting lead screw (5) and the pulling plate frame assembly (2) are rigidly connected at both ends of the front clamp (3) and the rear clamp (1) respectively to form an insulator tightening device; the front clamp (3) and one end of the rear card (1) are fixedly connected with the robot arm (7); its advantages are: it is suitable for robots to automatically replace low-value single-piece insulators at high altitudes, and the structure is simple and easy to realize automatic operation. .

Description

technical field [0001] This patent relates to a jig for replacing insulators, in particular to a jig for a robot that replaces ultra-high voltage and ultra-high voltage tensile single-piece insulators with electricity. Background technique [0002] Tension insulators are an important part of UHV overhead transmission lines. The function of the insulator is to electrically insulate the wire and the tower on the one hand, and to connect the wire and the tower mechanically on the other hand. However, during long-term operation, insulators are easily damaged by strong winds, thunderstorms, hail, ice and other severe weather, and deteriorate into zero-value or low-value insulators, which will further affect the normal operation of the power transmission network. cause large-scale power outages. For this reason, zero-value or low-value insulators must be replaced regularly. [0003] The operation method of insulator replacement is complicated, the working tools are bulky and he...

AI Technical Summary

Problems solved by technology

It is already very laborious for the construction workers just to lift the insulators, and it is almost impossible to replace the defective insulators without using other tools, and the tools used for construction are also very cumbersome

Therefore, the traditional manual operation method is very difficult even if the power is cut off. The manual operation method is not only labor-intensive, but also the working environment of the construction personnel is very dangerous.
