A link is respectively equipped with in the lower end of two support bars.
The present invention adopts such scheme, has the following advantages:
1, by crossing over coordinating of servicing unit and two head pulleys, the present invention can across obstacle, realizes working continuously in same shelves, improves operating efficiency.When running into barrier (splicing sleeve or finishing strips), first regulate the leap servicing unit being positioned at front side.Specifically, locking nut is unscrewed by instrument, the front and back position of adjusting screw(rod) in adjustment hole, auxiliary pulley and the distance between the head pulley of front side is made to be greater than the length of barrier, then locking nut is screwed by instrument, to maintain auxiliary pulley and the distance between the head pulley of front side.Then regulate the leap servicing unit being positioned at rear side, make the distance between the auxiliary pulley of rear side and the head pulley of rear side be greater than the length of barrier, concrete control method is the same.The present invention slides forward, and when barrier is between the auxiliary pulley and the head pulley of front side of front side, adjusting screw(rod) moves down.Specifically, unscrew locking nut by instrument, then by tool into rotation adjusting nut, screw rod is moved down, thus makes auxiliary pulley and conductive contact load, and then make the head pulley of front side power of unloading depart from wire, then screw locking nut by instrument.Regulate the leap servicing unit being positioned at rear side again, regulate its screw rod to move down, make auxiliary pulley and the conductive contact load of rear side, and then make the head pulley of rear side power of unloading depart from wire, concrete control method is the same.Now, the present invention relies on two auxiliary pulley loads, and two head pulleys unload power and depart from wire.The present invention continues to slide forward, when barrier is between the auxiliary pulley and the head pulley of rear side of rear side, (control method is the same to regulate two to cross over servicing unit, do not repeat them here), make two screw rods moves, two auxiliary pulleys unload power and depart from wire, two head pulley loads, now just can across obstacle.
2, on adjusting nut, be arranged with the first operating grip of two eccentric settings, locking nut is arranged with the second operating grip of two eccentric settings.Due to two first operating grips and two second operating grip eccentric settings, therefore without the need to using instrument just rotatable adjusting nut and locking nut, improve the convenience of maintainer's operation.
3, the lower end of two mounting panels exceeds auxiliary pulley to downward-extension.By this structural design, when auxiliary pulley load, head pulley unload power and depart from wire, when auxiliary pulley departs from wire accidentally, driving can also hang on wire, ensure that the personal safety of maintainer.
4, the side, top of every root support bar is provided with a mounting rod paralleled with it, top and the plate body of mounting rod are connected, the side of head pulley is flexibly connected with support bar, and the opposite side of head pulley is flexibly connected with mounting rod, and the lower end of mounting rod exceeds head pulley to downward-extension.By this structural design, when head pulley load, auxiliary pulley unload power and depart from wire, when head pulley departs from wire accidentally, driving still can hang on wire, ensure that the personal safety of maintainer.
5, the top of two support bars and two mounting rods lay respectively at the different side of two head pulleys.This structural design, has following two advantages: (1) improves balance of the present invention, makes the operation center of gravity of maintainer more close to the plumb line of hanging wire point; (2) when head pulley load, auxiliary pulley unload power and depart from wire, when head pulley departs from wire accidentally, driving still can hang on wire, further ensures the personal safety of maintainer.
6, the connecting rod being positioned at the top between two support bars is U-shaped bar.This structural design can be avoided between two support bars close to each other because there is deformation.
7, between two support bars the top connecting rod on be provided with suspension ring.Driving quick and stable can be pulled to overhead transmission line by suspension ring.
8, one end of two first poles and two support bars hinged, the other end of two first poles and one end of two second poles hinged, the other end of two second poles is connected by operation plate.This structural design, there are following three advantages: during (1) operation, maintainer opens operation plate, pin is placed on connecting rod, buttocks is sitting in or leans against on operation plate and carries out operation, the maintainer of different building shape can be adapted to, make it find the angle of the most comfortable, improve the operation comfortableness of maintainer; (2) make operation center of gravity more close to the plumb line of hanging wire point, enhance the balance of driving; (3) can fold, be easy to carry.
9, be respectively equipped with a link in the lower end of two support bars, be convenient to fixing rope ladder, thus make maintainer climb up driving along rope ladder.
