Special clamping tool for robot for live replacement of strain single insulator of ultrahigh-voltage line

Abstract

The utility model discloses a special clamping tool for a robot for the live replacement of a tension single insulator of an ultrahigh-voltage line. Each of a front clamp (3) and a rear clamp (1) comprises a main body (101) and an upper cover (102), wherein a collision block locking mechanism is arranged between the upper cover (102) and the main body (101); a motor locking mechanism (9) is arranged at the threaded connection part of the upper cover (102) and the main body (101); a motor (901) of the motor locking mechanism (9) is electrically connected with a robot controller; an adjusting lead screw (5) and a pulling plate frame assembly (2) are respectively and rigidly connected to two ends of the front clamp (3) and the rear clamp (1) to form an insulator tightening device; the end ofone side of the front clamp (3) and the end of one side of the rear clamp (1) are fixedly connected with a robot arm (7). The clamping tool has the advantages that the clamping tool is suitable for arobot to realize automatic replacement of the low-value single insulator at high altitude, the structure is simple, and automatic operation is easy to realize.

Description

technical field [0001] This patent relates to a jig for replacing insulators, in particular to a jig specially used for robots to replace strain-resistant single-piece insulators of ultra-high voltage lines. 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 heavy, and th...

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.
