Description
Technical field
The present invention relates to the specific purpose tool of power transmission line overhead ground wire suspension clamp and hardware fitting replacement, the ground wire suspension clamp of especially ± 500 kilovolts and ± 800 kilovolts of DC power transmission lines and the instrument of hardware fitting replacement。
Background technology
The particularity of 500 kilovolts and 800 kilovolts AC and DC power transmission line overhead ground wire hardwares, make when changing ground wire suspension clamp and gold utensil operation, load leading screw is installed without effective stress point, all have received yoke plate when changing ground wire suspension clamp gold utensil and affect the bulk of Impact direction, all occurring the situation of collision yoke plate when tightening up and loosen load leading screw, this all brings great potential safety hazard to operating personnel and equipment。
Summary of the invention
It is an object of the invention to provide the specific purpose tool changing overhead ground wire suspension clamp and gold utensil that one stable, that safety is higher, it may be achieved change the operation of ground wire suspension clamp and gold utensil。
The present invention is achieved through the following technical solutions: a kind of specific purpose tool changing overhead ground wire suspension clamp and gold utensil, one end is for being connected with tower material, the other end is for changing gold utensil by aerial earth wire, including connector, described connector includes the draw-in groove blocking tower material level one side, described draw-in groove upper end slot is towards being above bent to form the vertical fixation wall fixing with tower material another side, draw-in groove bottom land horizontally outward extends and is provided with hanging point, also include load leading screw, its one end is connected on hanging point, the other end is provided with shackle, load leading screw is connected with aerial earth wire by shackle。
A kind of specific purpose tool changing overhead ground wire suspension clamp and gold utensil utilize the structure of ground wire hanging point place tower material on shaft tower cooperate composition one new stress point, the side of being disposed to of new stress point avoids ground wire hardware tool duplex plate, and with the plumb line of ground wire in same direction。Two bolts of two screws on specific purpose tool and back-to-back 90 × 90mm tower material cooperatively form fixing stress point, and instrument lower surface draw-in groove formation second stress point mutually embedding with tower material, specific purpose tool is fixed on shaft tower by two stress points cooperations。Only need to being connected on specific purpose tool by one end of load leading screw, the other end of load leading screw is connected with shackle, and shackle is connected with ground wire again。The replacing of the lifting of ground wire, decline and ground wire overhanging golden tool can be realized by load leading screw
Compared with prior art, the invention have the advantage that the installation of load leading screw is easy in the instrument stress point position that can avoid ground wire hardware tool yoke plate that stretches out；Utilize tangent tower hanging point tower material bolt as fixing point, use original bolt to fix through specific purpose tool and tower material, solve former ground wire lifting device instrument factors of instability after stress；Extend outside instrument stress point, it is possible to meet the Impact direction of gold utensil in ground wire inside lock and outer corner situation；There is simple in construction, mechanical strength is high, security reliability is high advantage。Operation can alleviate the work of operating personnel powerful and shorten the activity duration。

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, present disclosure is described in further details。
Embodiment
Refer to shown in Fig. 1 and Fig. 2, a kind of specific purpose tool changing overhead ground wire suspension clamp and gold utensil, one end is for being connected with tower material 3, the other end is for changing gold utensil by aerial earth wire 6, including connector 1, connector 1 includes the draw-in groove 11 blocking tower material 3 level one side, draw-in groove 11 upper end slot is towards being above bent to form the vertical fixation wall 12 fixing with tower material 3 another side, draw-in groove 11 bottom land horizontally outward extends and is provided with hanging point 2, also include load leading screw 4, its one end is connected on hanging point 2, the other end is provided with shackle 5, load leading screw 4 is connected with aerial earth wire 6 by shackle 5。In the present embodiment, the connector 1 of specific purpose tool is mutually embedding with ground wire hanging point back-to-back 90 × 90mm tower material 3, the hanging point 2 on specific purpose tool top is connected with one end of load leading screw 4, the other end of load leading screw 4 is connected with shackle 5, shackle 5 is connected the instrument forming complete set with aerial earth wire 6, can be realized the replacing of the lifting of ground wire, decline and ground wire overhanging golden tool by load leading screw。
The using method of a kind of specific purpose tool changing overhead ground wire suspension clamp and gold utensil, comprises the steps:
(1), load and the leading screw of hardware fitting structure space length requirement are met according to the selection of O&M data；
(2), the specific purpose tool according to on-the-spot overhead ground wire suspension clamp and gold utensil
The form of ground wire and the structure of ground wire hardware tool hanging point shaft tower junction, measure it and hang space。Select the length of leading screw, and for the instrument with optical cable ground wire。
(3), personnel arrive on tower after setting, first the specific purpose tool of overhead ground wire suspension clamp and gold utensil be installed, then leading screw be installed and shackle is connected with aerial earth wire；
(4) after, having hung aerial earth wire back protection rope; checking tool connection; prevent replacing instrument from coming off; adjust and tighten up load leading screw so as to stress balance; finally check that the connection of Work tool guarantees that junction point connects well; in the complete stress of load leading screw, after ground wire connection gold utensil is rotatable, get final product lifting and the decline work of ground wire。
(5) remove, in order and change Work tool, remove backup protection rope, reach ground, tower under personnel。
