Description
Technical field:
The utility model relates to a kind of iron tower of power transmission line fastened by screw instrument, belongs to power system transmission line maintenance field.
Background technology:
In the process that iron tower of power transmission line group is stood and overhauled, need the fastened by screw work of a large amount of repeatability.In the process of fastened by screw, often there is the situation of bolt with cap rotation, need to bolt head be fixed can continue fastening.At present, what generally adopt is the method using spanner set bolt head and nut respectively, uses instrument many, and needs bimanualness.Meanwhile, because on tower, working space is limited, serious inconvenience is caused to work, reduce operating efficiency, add the danger coefficient of operating personnel.Hole may occur hindering the phenomenon of wrench operated relative to the position of tower material, makes spanner cannot set bolt head.
Utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of flexibility good, simple to operate, shorten the time of fastened by screw, improve the efficiency of tower erection, improve the security of work high above the ground, save the muscle power of operating personnel, reduce the iron tower of power transmission line fastened by screw instrument of the quantity of operating personnel's carrying implement.
The purpose of this utility model can be reached by following measure: a kind of iron tower of power transmission line fastened by screw instrument, it is characterized in that it comprises spline spanner, spline spanner connects connecting plate by connecting rod, connecting plate is nested with locking wrench, locking wrench is nested in connecting plate by the draw-in groove on connecting plate top, locking wrench connects ratchet spanner, and spline spanner and locking wrench all adopt coupling box spanner.
In order to realize the purpose of this utility model further, the distance between described spline spanner and draw-in groove is 100mm.
The utility model can produce following good effect compared with the prior art: the utility model can improve the convenience of fastened by screw, shortens the time of fastened by screw, and then shortens the time of tower erection and maintenance, improves the efficiency of tower erection.The utility model only uses an instrument to achieve the fastening of screw, minimizing operating personnel climbs the number of tools that pole tower operation needs to carry, simplify the operating procedure of operating personnel's work high above the ground, reduce the work high above the ground risk of operating personnel to a certain extent, simultaneously, in the process of fastened by screw, make the operating attitude that operating personnel keeps comfortable, improve the security of work high above the ground, save the muscle power of operating personnel.The utility model and use two spanners realize, compared with fastened by screw, having the advantages that flexibility is good, simple to operate.
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 50 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-65 seconds)=25000 seconds ≈ 6.94 hours
With a transmission line of electricity 50 base tower calculation, the completion time of project of a transmission line of electricity will shorten:
6.94 hours * 50 base ÷, 24 hours/day ≈ 14.46 days
Therefore, Novel electric power line tower fastened by screw instrument that is rational in infrastructure, easy to operate, that save 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.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of the A position of Fig. 1.
Detailed description of the invention: elaborate below in conjunction with the detailed description of the invention of accompanying drawing to utility model:
Embodiment: a kind of iron tower of power transmission line fastened by screw instrument (see Fig. 1, Fig. 2), it comprises spline spanner 1, prevents the screws when holding screw.Spline spanner 1 is linked together by connecting rod 5 and connecting plate 4, is locked between spline spanner 1 and connecting rod 5 by bolt 6; Can be fixed by closing-up at the first connecting portion 7 between connecting rod 5 and connecting plate 4.Connecting plate 4 top nested has locking wrench 2, locking wrench 2 is nested in connecting plate 4 by the draw-in groove 8 on connecting plate 4 top, locking wrench 2 can rotate and move left and right, and reaches the object that arbitrarily can regulate spline spanner 1 and locking wrench 2 spacing and fastened by screw.Distance between spline spanner 1 and draw-in groove 8 is 100mm, i.e. the distance of locking wrench 2 movement can reach 100mm, is greater than the spiro rod length of all shaft tower bolts.Locking wrench 2 connects ratchet spanner 3, is welded and fixed between locking wrench 2 and ratchet spanner 3 by the 3rd connecting portion 9, and ratchet spanner 3 can rotate and reverse by regulating realization.Spline spanner 1 and locking wrench 2 all adopt coupling box spanner see Fig. 2, can ensure can be held in hex bolts or hexagonal (hexagon)nut from all angles, thus like a cork by tool card on screw rod, by regulating the position of locking wrench 2, while making spline spanner 1 be fitted in bolt head, locking wrench 2 fits tightly on nut, rotating ratchet spanner 3, it is mobile that locking wrench 2 drives nut not stop on screw rod, move to spline spanner 1 direction during fastened by screw, move to draw-in groove 8 direction when loosening, finally complete fastened by screw and loosening work.
Claims (2)
1. an iron tower of power transmission line fastened by screw instrument, it is characterized in that it comprises spline spanner (1), spline spanner (1) connects connecting plate (4) by connecting rod (5), connecting plate (4) is nested with locking wrench (2), locking wrench (2) is nested in connecting plate (4) by the draw-in groove (8) on connecting plate (4) top, locking wrench (2) connects ratchet spanner (3), and spline spanner (1) and locking wrench (2) all adopt coupling box spanner.
