Description
Technical field
The utility model relates to electric equipment maintenance technical field, specifically relates to a kind of straight line shoulder pole card for changing straight line list insulator string string.
Background technology
China is one of country carrying out live line working the earliest in the world, and 500kV and following line live-line work conventional project carry out corresponding multiplexer development quite ripe experience; But 750kV grade circuit is new voltage order one grade, due to the particularity of line construction, objectively determine to use for reference and can not indiscriminately imitate or directly apply 500kV and following line live-line work conventional project, carry out the technology of corresponding multiplexer development, data and experience, and must in conjunction with 750kV circuit concrete condition, carry out series, science, the exploitation of the research of live line working project targetedly and Work tool, that serves 750kV live line working carries out needs.
Traditional 500KV straight line shoulder pole card structure is connected with jig main body by lifting spindle with insulation pull-rod, and jig six hook catches on six wires, and lifting spindle seat is placed on circuit angle steel.When changing the string work of straight line list insulator string, operator tightens up leading screw, mentions wire, and lax insulator string is namely replaceable.The shortcoming of this jig is that jig directly carries wire, and jig easily hurts conductive line surfaces and easily makes wire occur bending and deformation.In addition, after wire occurs bending and deformation, directly impact connects the adjustment of pull-rod, and required screw travel is just long, causes difficulty of processing to increase, and jig is heavy, and cost is larger.
For the present situation of 330 ~ 500kV transmission line of alternation current live working tools, be necessary to develop the Work tool being applicable to carry out 750kV line live-line work conventional project.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency existed for prior art, and provide one jig when changing straight line list insulator string string not hinder wire, structure is simple, the straight line shoulder pole card for changing straight line list insulator string string easy and simple to handle.
A kind of straight line shoulder pole cartoon for changing straight line list insulator string string of the utility model is crossed following technical proposals and is achieved: a kind of straight line shoulder pole card for changing straight line list insulator string string comprises jig main body, base base screw, lifting sub, hydraulic screw rod, described base is seated on circuit angle steel, jig main body is connected with base by base screw, jig main body two ends are connected with hydraulic screw rod, hydraulic screw rod is connected with lifting sub by insulation pull-rod, and lifting sub is connected with line hardware connecting plate by connecting bolt.
A kind of straight line shoulder pole card for changing straight line list insulator string string of the utility model has following beneficial effect compared with prior art: the jig for changing straight line list insulator string string of a kind of 750KV of being suitable for circuit of the utility model design, jig does not directly carry wire, but directly carry yoke plate, overcome the various shortcoming that 500KV straight line shoulder pole card exists.Tighten up leading screw during work, line hardware yoke plate is mentioned in lifting sub, lax insulator string, namely replaceable.This shoulder pole card replacement insulator string, direct lifting yoke plate, there is no lifting lead wire, such jig can not hurt wire, and wire also can not occur bending and deformation, and screw travel is short, the fixture structure that the utility model provides is simple, lightweight, easy and simple to handle, bring conveniently to the operation of electrified replacing linear list insulator string string.
It should be noted that in addition, existing 500KV straight line shoulder pole card is suitable only on the angle steel that is seated on line hardware, and the 700KV straight line shoulder pole card that the utility model provides not only is suitable for being seated on the angle steel on line hardware but also is suitable for being seated on channel-section steel, universal performance is relatively good.
