Summary of the invention
It is little that the utility model is primarily aimed in the prior art contact-making surface, causes the lead damage, staff's shortcoming such as come to harm, invented a kind of device that 110kV ~ 500kV circuit promotes lead that is used for wire clamp function, make work convenient, safety, and lead is injury-free.
Above-mentioned technical problem of the present utility model is implemented by the following technical programs.
A kind of device that is used for 110kV ~ 500kV circuit lifting lead, comprise vertical gusset piece, the gusset piece upper end is hook, gusset piece is horizontally arranged with symmetrical connector, connector is provided with permanent joint or active joint, and permanent joint or active joint are connected by brazier head screw with thread-lifting hook; Described thread-lifting hook is provided with cover plate, and cover plate one side is connected with thread-lifting hook by pin, and the cover plate opposite side passes the split pin that is arranged on the thread-lifting hook, and split pin is provided with hex nut.Increase flip structure, make thread-lifting hook have the effect of wire clamp, in the process that promotes lead, lead is clamped fixing, has avoided the situation of accidental release, downslide.
As preferably, described hook is fixed on the top of gusset piece by hex bolts, packing ring, nut.Hook is as the connecting portion of this device with other objects.
As preferably, be provided with down fixture block in the middle of the described thread-lifting hook, the centre of cover plate is provided with fixture block.
As preferably, the width of described fixture block down and last fixture block all is wider than the width of thread-lifting hook or cover plate.
Fixture block is set, and purpose is to increase the contact area of lead and thread-lifting hook, avoids the lead part to be subjected to excessive pressure and causes fracture or damage.
As preferably, described fixture block down, to go up fixture block and be semicircle, the centre is provided with rubber packing.The elasticity that rubber packing has can be adjusted interaction face and active force between fixture block and lead at any time, reaches optimum clamping dynamics; Frictional resistance between rubber packing and lead is big, and lead is more firm in lifting process.
As preferably, described permanent joint and connector are for being wholely set, and active joint is connected by pin with connector.Be wholely set, reduce production process; The active joint that pin connects is set, increases the flexibility ratio of thread-lifting hook, same device can promote the lead of different directions.
The utility model compared with prior art has following advantage.
The utility model card line is firm, supporting bracket and thread-lifting hook flexibility and changeability, and the scope of application is wider; The fastness of clamp is strengthened in the design of renovating, and rubber packing cooperates the lead of different size, even adjust contact-making surface and interaction force, reaches to hold preferably and puts forth effort, and effectively avoids damage wires, and causes the staff to come to harm thus.
