Description
Technical field
The utility model relates to the U-shaped fastened by screw device of a kind of hull wire clamp.
Background technology
The insulation property quality determines operating personnel's safety and the security of operation of transmission line in the live line working process, and operating personnel and earth electrode must keep regulation in " State Grid Corporation of China's electric power safety working regulation (circuit pack) " in the equal potential working process.66kV electric power line pole tower edge is 1500mm far from the distance of wire, in operation process, deduction person left and right distance is 600mm, only remain 900mm, the safe distance of the person and electrified body must not be less than 700mm during the regulation live line working in " State Grid Corporation of China's electric power safety working regulation (circuit pack) ", as the equipotential electrician, in operation process, will adjust job position and swings remaining margin of safety when excessive and almost can not meet the demands.and upper peace type arrangement upper conductor can not carry out equal potential working due to the safe distance deficiency, can only wait for has a power failure processes when the U-shaped screw of wire clamp moves back after buckleing, important transmission line can not have a power failure for a long time, wire clamp loses to hold and puts forth effort, after long-play under the impact of meteorologic factor, make the sag deflection span of wire a side, go down according to this other insulator strings produce displacements, can not meet in " 110kV-500kV overhead power line construction and acceptance specification " installation requirement to insulator string, so just can not meet the requirement of transmission line safe operation.The competency profiling of equal potential working method to the operating personnel, operative skill, the composition of Work tool, the condition of operation has very high requirement, and is indispensable otherwise difficultly complete this subjob.
In the earth potential working method, need only and can guarantee enough safe distances, the insulation property that operation tool is good, the operative skill that the operating personnel is skilled just can be processed the part defect timely, thereby while guaranteeing the existing equipotential Electrician Operation of safe and stable operation of transmission line, but when the present U-shaped loosened screw of 66KV wire clamp or loss operation, safe distance is had relatively high expectations, adopt common fastener, can only carry out U-shaped fastened by screw when having a power failure, still there is the unsteadiness of equipment, still have labour intensity large, ineffective problem exists.
The utility model content
The purpose of this utility model is to provide the U-shaped fastened by screw device of a kind of hull wire clamp, can only power failure operation with what overcome that currently available technology exists, and labour intensity is large, ineffective problem.
The purpose of this utility model is to be achieved through the following technical solutions:
The U-shaped fastened by screw device of a kind of hull wire clamp, comprise sleeve, in sleeve, be provided with spring steel plate, the below of spring steel plate is provided with and cogs, and the top and bottom that cog are provided with the fixed insulation bar, and the fixed insulation bar is fixedly connected with sleeve, the center that cogs is provided with rotating shaft, rotating shaft connects lower gear, and the top and bottom of lower gear are fixedly connected with the rotation insulating bar, and described rotating shaft lower end is connected with the rotation insulating bar by fixed screw.
Further, described spring steel plate lower end is connected with magnet, and the outer rim of magnet is fixedly connected on the inwall of sleeve.
Further, the inwall of described sleeve is provided with some friction teeth.
Further, the outer end of described rotation insulating bar is connected with joint.
The beneficial effects of the utility model are: simple in structure, reasonable in design, easy to operate, fail safe is good; When electric wire normally moves, needn't use the equal potential working method just can carry out the relevant operations such as fastened by screw; Increased the serviceability rate of equipment and reduced frequency of power cut, having guaranteed good power supply reliability.
