Abstract
The invention discloses a multifunctional suspension insulator string cross arm side hardware fitting replacement fixture, which comprises a cross arm side fixture, a lead side fixture and a frapping device. The cross arm side fixture comprises a first fixture and a second fixture. When the fixture is used, the first and second fixtures can be freely selectively arranged in a required way according to the form of a cross arm end. When fixing holes on the upright sides of T-shaped structures of the first and second fixtures connect the first and second fixtures by utilizing connecting parts, a relative distance between the two fixtures can be regulated according to the needs of the cross arm end. Simultaneously, a position at which the arrangement of the frapping device is required can be regulated by utilizing through holes on one transverse side of each of the T-shaped structures of the first and second fixtures to enable cross arms with different widths to enter the frapping device for fit with an insulator socket fixture. The lower part of each of the first and second fixtures has a ladder-like structure so as to be adaptively arranged on a planar tower material and clamped to angle iron and the like.
Description
Technical field
The present invention relates to a kind of suspension insulator and change jig, particularly a kind of multi-functional suspension insulator cross-arm side gold utensil is changed jig.
Background technology
Owing to move in the ultra-high-tension power transmission line long term exposure lowered in field environment, bearing wind, drenching with rain, airborne impurity and the effect that colds and heat succeed each other etc., gold utensil produced wear and tear, get rusty, defective such as corrosion.And the replacing conventional method of " suspension insulator cross-arm side gold utensil " is: personnel utilize wire grip to tighten up lead to make insulator string loose on the bar, cooperated by the ground staff then insulator string is sling, and carry out the replacing of cross-arm side gold utensil again.But since 35-220kV circuit straight line pole, strain insulator shaft tower wire jumper suspension insulator be in mostly landform, bar type complexity, and high tower etc. locate.Therefore power tool and operational method not only waste time and energy like this, and operation is loaded down with trivial details.Though people also develop some suspension insulator cross-arm side gold utensils at present successively and change jig, but these jigs are are often just researched and developed at the cross-arm head of a certain specific assembling mode, therefore range of application is too narrow, versatility is poor, this just causes a maintenace point need be equipped with the jig of many covers to adapt to multiple cross-arm head, to using, depositing and brought great inconvenience.
