Live working R-type pin remover

Abstract

The invention relates to a live working R-type pin recover which comprises a base, a linkage rotary shaft, a pin removing head, a drive rod, an operation rod component and a tension spring, wherein one end of the base is provided with a rotary socket, and the other end is provided with a guide slot; the linkage rotary shaft is inserted in the rotary socket; the pin removing head is matched with the guide slot; one end of the drive rod is connected with the pin removing head, and the other end is connected with the linkage rotary shaft through a rotary shaft connection plate; the operation rodcomponent is in pivot joint with the linkage rotary shaft; and the tension spring connects the base and the operation rod component. The live working R-type pin remover has the outstanding substantive characteristics: the shape of the pin remover is changed, and the pin remover can be independently used to smoothly remove an R-type pin and replace an insulator in live working situations. By rotating the operation rod, an operation strut, the linkage rotary shaft, the rotary shaft connection plate and the drive rod can be sequentially driven to act so as to drive the pin removing head to pull out the R-type pin; and during pin removal, only the operation rod (made of insulator materials) needs to be operated, thereby ensuring that the pin remover is suitable for live working. In the process of removing the R-type pin, a matched insulator pin ball connecting rod can be used for clamping and positioning, and the swing of the insulator is avoided, thereby improving the smoothness of the removal work.

Description

technical field [0001] The invention relates to a pin removal tool for replacing insulators in high-voltage transmission lines, in particular to an R-type pin removal device for live work. Background technique [0002] Live work is an engineering technique in which workers touch live electrical equipment or operate live electrical equipment with operating tools, equipment, and devices. In the operation and maintenance of transmission lines, live operation relies on its unique technical advantages to maintain and repair the lines without power failure, so as to avoid various losses caused by power failures. [0003] However, with the continuous development and improvement of line equipment, the original live working tools can no longer meet the needs of current live working. For example, R-type pins have been widely applied to insulators of lines, and the original live work pin remover cannot take R-type pins while electrified, which results in that insulators using R-type p...

[0003] However, with the continuous development and improvement of line equipment, the original live working tools can no longer meet the needs of current live working work.

For example, R-type pins have been widely used on line insulators, but the original live work pin remover cannot pick up R-type pins while live. Specific Conditions for R-type Pins to Conduct Live Work
