Abstract
The utility model relates to an insulating gap bridge for repairing power lines, comprising a gap bridge main body which is made of insulating material; one end of the gap bridge main body is provided with a rod tower cross arm hook, and the other end of the gap bridge main body is provided with a hanger; the gap bridge main body consists of an inner box body and an outer box body; the outer box body is sheathed at the periphery of the inner box body; one end of the outer box body is provided with the rod tower cross arm hook by a sleeve hoop; a rotatable pin shaft is arranged between the rod tower cross arm and the sleeve hoop; one end of the inner box body is provided with the hanger by the sleeve hoop, a rotatable pin shaft is arranged between the sleeve hoop and the hanger; and the other end of the outer box body is sheathed at the periphery of the inner box body. In the insulating gap bridge for repairing the power lines, two ends of the gap bridge main body are provided with the rod tower cross arm hook and the hanger, when being used, the insulating gap bridge can be hung at proper positions at a rod tower and the insulated front end, and an operator can lead out lines along the gap bridge main body for operation, so that an insulator umbrella skirt is avoided being trampled in the operation process.
Description
Technical field
The utility model relates to electric power transmission line maintenance servicing unit, specifically is that a kind of insulation that is used for the power circuit maintenance is passed a bridge.
Background technology
In the insulator installation and maintenance process of power circuit, when the maintainer goes out line process aloft, need balance to stand and walk, to guarantee its safety along the certain distance span.And when practical work process, the frequent pin of staff is stepped on the insulator full skirt, can not guarantee its balance on the one hand, tramples on the insulator full skirt on the other hand easily, and influence is installed or maintenance work.Owing to be operation aloft, also adopt bucket arm vehicle lifting operating personnel sometimes, but this mode inefficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of insulation that is used for the power circuit maintenance to pass a bridge, the technical problem that the operating personnel trampled on the insulator full skirt easily when the described this insulation gap bridge that is used for the power circuit maintenance will solve the I﹠M of prior art insulator.
The purpose of this utility model is achieved through the following technical solutions: comprise the gap bridge main body, the gap bridge main body is made of insulating material, gap bridge main body one end is established the shaft tower cross-arm and is had contact with, the gap bridge main body other end is provided with hook, the gap bridge main body is made of internal box and outer case, outer case is sheathed on the internal box periphery, outer case one end is provided with the shaft tower cross-arm by cuff and has contact with, the shaft tower cross-arm have contact with and cuff between be provided with rotating bearing pin, internal box one end is established hook by cuff, be provided with rotating bearing pin between cuff and the hook, the outer case other end is sheathed on the internal box periphery.
On outer case, be provided with groove, on internal box, be provided with bolt hole, in the groove of the bolt hole of internal box and outer case, be equipped with bolt along its length direction.
The shaft tower cross-arm have contact with and cuff between the bearing pin place be provided with lock-screw, cuff and the hook between the bearing pin place be provided with lock-screw.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model is provided with the shaft tower cross-arm at the gap bridge main body two ends that the insulation that is used for the power circuit maintenance is passed a bridge and has contact with and hook, can be mounted on shaft tower and insulation front end proper site in use respectively, the operating personnel can be along the outlet of gap bridge main body, carry out operation, avoided trampling on the insulator full skirt in the industry process, the shaft tower cross-arm have contact with and the cuff of hook and gap bridge main body between be provided with rotating bearing pin, can avoid the gap bridge main body too being tilted because of the two ends articulated end is not vertical state, this gap bridge main body is made of outer case and internal box, be connected by bolt, be convenient to regulate the length of gap bridge main body, to adapt to the maintenance of insulator under the different situations.This insulation gap bridge weight is little, is easy to carry.
