Special installation rod of U-type seat

Abstract

Provided is a special installation rod of a U-type seat. An L-type support arm and a fixed pulley group are installed on left and right sides of a support bench. A through hole on which a rubber leather bowl is installed is arranged in a horizontal arm of the L-type support arm. The rubber leather bowl has a cone-shaped outer wall, a downward big end and a cone-shaped inner cavity. A chamber of the inner cavity is gradually shrunk from top to bottom. One end of a pull rope is fixedly connected with the rubber leather bowl and the other end is successively wound around a first pulley and a second pulley and then is freely hung from the second pulley. The support bench sleeves the upper end of an outer rod 1. An inner rod 1 is capable of performing axially linear movement relative to the outer rod 1 and axially rotating. The lower end of a fastening rod is threaded into an oil cavity of the outer rod 1 and then is fixedly connected with the upper end of the inner rod 1, so the fastening rod is capable of performing axially linear movement relative to the outer rod 1 and axially rotating. An axial hexagonal prism blind hole is arranged in the upper end face of the fastening rod. According to the invention, the special U-type seat on a bird repellent device is connected with and fixed on the L-type support arm via a cone-shaped column on the U-type seat, so live-line work and installation of the bird repellent device can be achieved and a problem of long time of power outage for installation of the bird repellent device is solved.

Description

technical field [0001] The invention relates to the field of power transformation application equipment, in particular to a special mounting rod for a U-shaped seat used for installing the U-shaped seat at the lower end of a bird repellent. Background technique [0002] Since the power supply lines are mostly located in the suburbs and are elevated, the duration of the power supply lines will be "harassed" by birds' nesting. According to statistics, the faults of power distribution lines caused by bird nesting have been on the rise in a straight line in recent years. The reason is related to the current indiscriminate logging and the continuous expansion of human activities. Birds nesting on power supply towers will seriously threaten the safe power supply of power distribution lines, so effective measures must be taken to stop them. At present, it is mainly to clean up the bird's nest after finding the bird's nest during line inspection, which is far from enough to realize...

AI Technical Summary

Problems solved by technology

Because the power distribution line is long, if the bird repellent is installed according to the current installation method of the bird repellent, and at the same time limited by the small number of personnel, multiple power outages are required. On the one hand, it will bring a lot of inconvenience to electricity customers, on the other hand , During the installation process, it is necessary to climb to the top of the tower to operate. The whole process is not only intensive but also poses a major hidden danger to the safety of operators.
