Insulator bracket fastening device for replacing strain insulator of power transmission line

Abstract

The invention discloses an insulator bracket fastening device for replacing a strain insulator of a power transmission line, mainly composed of a rolling mechanism with a locking function, and a fixing base connected to the lower end part of the rolling mechanism; the rolling mechanism comprises a rotatable base; a tape coiling rack with a rocking handle is hinged at the upper part of the rotatable base through a moving connecting shaft; a locking mechanism capable of locking the expanding angle between the tape coiling rack and the rotatable base is configured on the moving connecting shaft; a tape coiling cylinder for coiling a transmission tape is connected to the tape coiling rack through a moving rotating shaft; a controllable transmission tape elastic clamp is configured on the tape coiling rack; the fixing base capable of rotating relatively is hinged at the lower part of the rotatable base at least through one connecting bolt; the rotatable base and the fixing base at the lower part are connected together through a fixing bolt and a moving bolt; and a controllable two-gang board clamp is arranged on the bottom surface of the fixing base. The device is featured by simple and reliable structure and convenient installation and use.

Description

technical field [0001] The invention relates to a special auxiliary tool for replacing the tension insulator of the transmission line in the electric power maintenance work, especially for lifting and fastening the bottle holder when replacing the insulator on the transmission line of the tension tower Replace the strain insulator support bottle holder fastening device for the transmission line. Background technique [0002] In the daily operation, maintenance and inspection of power transmission lines in the power system, when the insulator is damaged or self-exploded, it needs to be replaced in time. When using the big knife clamp to replace the strain insulator, the bottle holder is an indispensable replacement tool. However, through the usual maintenance work, it was found that when the bottle holder is used in conjunction with the fixture, the head end is fixed to the side connecting plate of the pole tower with long bolts, while the tail end needs to be tightened by th...

AI Technical Summary

Problems solved by technology

Since the tail end of the bottle holder needs to be tied by manpower, it is time-consuming and labor-intensive, and the physical fitness of the maintenance personnel is uneven. If the rope is not tied firmly, it will easily cause the bottle holder to tilt, and the insulator string is easy to come out of the bottle holder. Potential safety hazards are caused for maintenance work, and work efficiency is reduced; the reason for the above is that the way of manually bundling ropes is unreasonable, which may easily cause insulators to loosen and fall off
