It is convenient that the technical problem to be solved in the present invention is to provide a kind of operation, can reduce operating personnel on tower, and operating efficiency is high, the direct current high tension transmission line maintenance method that fail safe is good and safe chair lift.
Technical solution of the present invention is:
A direct current high tension transmission line maintenance method, step is as follows:
A. workmen's I is carried rope and a transmission pulley with anti-falling locking device is climbed cross-arm place, and transmission pulley is fixed on cross-arm, and rope one end is lifted to end through described transmission pulley and transmitted, fall earthward;
B. workmen's II is fastened the lifting end of rope to be positioned at ground safe chair lift upper end, workmen's I is that stiff end is thrown away ground by the other end of rope, by workmen's II, stiff end is fixed on the ground, workmen's II is by pulling rope to make safety seat rise to cross-arm place;
C. workmen's I is seated in safety seat, after fixing, by workmen's II, pulls rope to job position, and workmen's I starts service work;
D. after service work completes, workmen's II pulls rope that safety seat is risen to cross-arm place, and workmen's I is climbed on cross-arm, and workmen's II is put rope safety seat is dropped to ground, and the stiff end unhitching; Workmen's I is walked around transmission pulley by the stiff end of rope and is thrown away on ground, and workmen's I unloads transmission pulley, carries transmission pulley and gets back to ground.
A kind of direct current high tension transmission line maintenance Special safety chair lift, there is a suspension bracket, its special character is: the crown center position of suspension bracket arranges suspension ring, the middle part of suspension bracket and bottom are chair frame shape, the backrest place top bend forward of suspension bracket, and the backrest place of suspension bracket is provided with rod, on suspension bracket, between rod, be provided with safety belt, the seat support place of the corresponding chair frame in suspension bracket two ends arranges handrail, in the seat position of the corresponding chair frame of suspension bracket, seat board is set, and in the bottom of suspension bracket, pedal is set.
Before and after described pedal, be provided with the upwards card edge of bending, the moving range of control pin, increases fail safe.
The corresponding pedal position in suspension bracket bottom is provided with safety rope, and shank is played to constraint effect, improves fail safe.
In pedal surface, there is a plurality of small sircle holes, weight reduction.
Before and after described seat board, edge is bent to form edge downwards, to improve the intensity at seat board edge, and workmen is sitting in above feel comfortably cool.
The invention has the beneficial effects as follows: can replace hanging ladder in the past to carry out operation, operation is convenient, only need two people's operations, people's operation on tower, another person's operation under tower, reduces operating personnel on tower, operating efficiency is high, improved the fail safe of operation, the safety seat that uses is simple in structure, be easy to carry, lightweight.
