Description

Use stable brake pull rod

Technical Field

The application relates to the field of equipment for electric power overhaul, in particular to a brake pull rod stable in use.

Background

When the electric power system circuit is overhauled, the electric power system circuit needs to be opened, closed and overhauled. Since these power system lines are typically high and may be live, an operator typically stands on the ground, holds one end of the trip bar, and uses the other end of the trip bar to operate the switch.

The brake pull rod that currently generally uses includes the body of rod and sets up the pole head at body of rod top, and the pole head includes the montant and sets up the horizontal pole in montant intermediate position department perpendicularly, and the horizontal pole is used for stirring, dismantles and overhauls the switch. When utilizing brake pull rod to carry out the operation, and when needing to change the part that damages, will damage the installation ring cover on the part and establish on the horizontal pole, utilize the body of rod to drive the part and remove, and accomplish the dismantlement that damages the part, then will treat new parts cover of changing and establish on the horizontal pole, the body of rod drives the horizontal pole and removes, the horizontal pole drives new parts and removes, and transport the eminence with new parts from ground, accomplish the installation of new parts, however, under some rugged operation environment, especially under strong wind weather, new parts transports the in-process to the eminence from the low, the installation ring on the new parts is easily fallen from the horizontal pole by strong wind effect, waste time and energy.
