Embodiment
The structure of the utility model earth potential live operation glass insulator R pin pin removals is made into one below in conjunction with the accompanying drawings
Walk explanation.
As shown in Figure 1, the utility model earth potential live operation glass insulator R pins pin removal is mainly by insulating bar 1, branch
Bracer 2, upper strut 3-1, rotation coupling head 5, leading screw 6, thread bush 7, thread 8, R pin drag hooks 9 form.
Thread bush 7 and upper strut 3-1 parallel arrangements, the top of supporting rod 3-1 is formed by connector 10 and thread bush 7 cuts with scissors
Connect, thread bush 7 is fixedly connected by rotating coupling head 5 with insulating bar 1, and the top of leading screw 6 is installed in thread bush 7, leading screw 6
Middle part is connected through a screw thread mode and is provided with the tightening of 6 both ends of control leading screw or flexible thread 8, the bottom installation R of leading screw 6
Drag hook 9 is sold, the lower part of supporting rod 7 and the lower part set of leading screw 6 pick up the supporting block 2 of position-limiting action；R pin drag hooks 9 are small cross bar
Part, its one end can be stretched into the hole of R pins 12, and the other end is formed a fixed connection by fixing piece 11 and the bottom of leading screw 6；Upper support
The bottom of bar 3-1 is connected with a half arc fixture block being stuck on insulator steel cap, and the recess of the half arc fixture block is downward.
When need to pull out R pins 12 go out pin when, need double compounding practice, people's both hands hold insulating bar 1 and operate upper support bar 3-1
Half arc fixture block be stuck on the steel cap of insulator 4, and R pin drag hooks 9 is hooked in the hole of R pins 12, another people pushes and pulls screw thread and draws
Bar 8 is tightened leading screw 6 and is moved up, while drives R pin drag hooks 9 to pull up R pins 12, completes out pin work.
When needing R pins 12 being pressed into use, upper support bar 3-1 is changed to lower support bar 3-2, as shown in Fig. 2, lower branch
Half arc fixture block on the steel cap that strut 3-2 connections one are stuck in insulator 4, the recess of the half arc fixture block is upward.During operation,
Double compounding practice is needed, people's both hands are held the operation of insulating bar 1 lower support bar 3-2 and are stuck on the steel cap of insulator 4, and sell R
Drag hook 9 is hooked in the hole of R pins 12, and another people, which pushes and pulls thread 8, to be stretched out leading screw 6 and move down, while drives R to sell drag hook
9 pressure R are sold into pin, so as to complete to work into pin.
Supporting block 2, upper support bar 3-1 and lower support bar 3-1 described in the utility model use high-strength aluminum alloy material
7A04 is fabricated, and supporting block 2 can slide up and down along supporting rod and screw, and when operation makes R pin drag hooks just correspond to what R was sold
Position.
