The purpose of this utility model can be reached by following measure: a kind of transmission tower fastened by screw aid, it is characterized in that it comprises connecting rod turnbarrel, connecting rod turnbarrel is connected loop bar by the first connection loop bar and second and forms, first connects loop bar by head rod body) to be fixedly connected with coupling box and to form, coupling box is the inner hollow cylinder in bihexagon, second connects loop bar is made up of the second connecting-rod body and dicyclo sleeve connection, dicyclo sleeve is that a sleeve outer wall is excised the cylindrical sleeve of 300 ° of sidewalls from 1/3 height to 2/3 height component, dicyclo sleeve is fixedly connected with the second connecting-rod body, coupling box is enclosed within dicyclo sleeve inner and can rotates freely, the end of head rod body and the second connecting-rod body is equipped with screw thread, connect the first screw shell respectively, second screw shell, first screw shell is threaded one end of head rod, second screw shell is threaded one end of the second connecting rod, the other end of head rod and the other end of the second connecting rod connect a connecting rod collar respectively, each connecting rod collar is equipped with rotating switch controller, all ratchet is embedded with in each connecting rod collar, head rod body is contrary with the second connecting rod threaded one end direction with head rod with the second connecting-rod body end thread direction.
The utility model can produce following good effect compared with the prior art: the utility model is that the feature utilizing electric power line pole tower main material connecting screw mostly to adopt double alternating expression to arrange is developed, in the process of iron tower of power transmission line fastened by screw, realize the fixing of bolt with more effective means, facilitate fastened by screw work can to complete within the shortest time.The multiple position of the utility model takes the design of adjustable length and adjustable angle, the fastening of steel tower different parts screw can be adapted to, and sleeve wall thickness thin, there is no lever, also the fixing of bolt can be realized in the space of bolt head and tower material close together, solving spanner can not the problem of set bolt when screw and tower material close together, the quantity of set bolt is many, can fix three bolts at most simultaneously, avoids the puzzlement using spanner to need constantly adjustment.Adopt the mode that fixing at 3, bolt can be made mutually stressed in fastener cycle, do not need manually to exert all one's strength fixing, operating personnel can only make a hand firmly by the utility model, the adjustment of convenient high aerial work posture, convenient working personnel keep comfortable operating attitude, reduce the risk of work high above the ground, improve the security of operating personnel's work high above the ground, there is good stability.Improve operating efficiency.
Due to application of the present utility model, the operating efficiency of standing for improving electric power line pole tower group and overhauling serves great impetus, shortens the time of tower erection and maintenance, duration of a project and power off time is greatly reduced, improves the reliability of power supply.The utility model makes shorten to 60 seconds by 90 seconds the average time of a fastened by screw, and calculate according to a base steel tower 1000 screws, the time that a base steel tower is saved in fastened by screw work is:
1000 * (90 seconds-60 seconds)=30000 seconds ≈ 8.3 hours
With a transmission line of electricity 50 base tower calculation, the completion time of project of a transmission line of electricity will shorten:
8.3 hours * 50 base ÷, 24 hours/day ≈ 17.2 days
Therefore, the utility model is rational in infrastructure, easy to operate, saving muscle power, has stronger practicality, objectively safety benefit and economic benefit, is adapted at electric power line pole tower group and stands and use on a large scale in service work.Meanwhile, the other field needing fastened by screw to face same problem can be generalized to.
