Insulator is fixed on by skidding group on portal frame, and insulator, pulley blocks, hand capstan are connected using steel wire rope
Together, it realizes and insulator is moved up and down.
The hand winch offers mounting hole, by the hand winch by wearing fixing bolt in the mounting hole
It is fixed on the portal frame；The hand winch includes bearing and to be set in the bearing outer and around the capstan winch that bearing rotates,
The capstan winch is provided with crank.
The hand winch further includes positioning pin and safety lock, and the crank offers through hole, and the positioning pin passes through
It is fixed with the portal frame after the through hole, and the positioning pin is locked using the safety lock.The use of positioning pin, can
Prevent hand winch stress from rotating；Safety lock can lock positioning pin, prevent irrelevant personnel from opening positioning pin, causing need not
The loss wanted.
It is provided with safe fence around the sub- suspension arrangement of analog insulation.The installation of safe fence can avoid unrelated people
Member enters in device.
It is compared with the prior art, the advantage of the invention is that：Device design is simple, and low manufacture cost, installation are easy, no
It is affected by environment, from safeguarding；It movable pulley number can be increased according to scene reach best and save force mode, it can be with using the device
Quickly, flexible, safe efficient development disc insulator pollution degree test；It is easy to use, it is time saving, laborsaving, economical, safe；It is not necessarily to
It ascends a height, without arranging equipment to have a power failure, there is higher social economic value.

Embodiment
It is a kind of sub- suspension arrangement of analog insulation refering to fig. 1 to Fig. 3, including portal frame 2, the hand that is fixed on portal frame 2
Dynamic capstan winch 7 for suspension insulator 1 and controls skidding group and steel wire rope 6 that insulator 1 moves up and down；Pulley blocks include the
One fixed pulley 4, the second fixed pulley 5 and movable pulley 3, the first fixed pulley 4, the second fixed pulley 5 are separately fixed on portal frame 2；Steel
6 one ends wound of cord is on hand winch 7, after the other end sequentially bypasses the second fixed pulley 5, movable pulley 3, the first fixed pulley 4
It is fixed on the upper end of movable pulley 3.
Insulator 1 is fixed on by skidding group on portal frame 2, using steel wire rope 6 by insulator 1, pulley blocks, hand capstan
It is cascaded, realizes moving up and down to insulator 1.
Hand winch 7 offers mounting hole 15, is fixed hand winch 7 by wearing fixing bolt 9 in mounting hole 15
On portal frame 2；Hand winch 7 includes bearing 16 and is set in bearing 16 outside and around the capstan winch that bearing 16 rotates, capstan winch setting
There is crank 8.
Hand winch 7 further includes positioning pin 12 and safety lock 13, and crank 8 offers through hole 14, and positioning pin 12 is passed through and passed through
It is fixed with portal frame 2 after perforation 14, and utilizes 13 locking positioning pin 12 of safety lock.The use of positioning pin 12 can consolidate crank 8
It is scheduled on portal frame 2, and can prevent 7 stress of hand winch from rotating；Safety lock 13 can lock positioning pin 12, prevent unrelated
