Pawl, grasping beam center is provided with screwed hole, and jackscrew is threadedly coupled with grasping beam, and the tail end of jackscrew is hexahedron, and the screw front end of jackscrew is in
Taper.
Anti-disassembling nut is installed and method for dismounting, is comprised the following steps that：
When a. installing, bolt is installed in place with anti-return nut, ball is glued into the through hole that a little glycerine is put into anti-return nut
It is interior；
B. side of the retaining gland with the conical surface is scheduled on ball surface, takes the installation tool of anti-disassembling nut, will cover jacket casing
On retaining gland, sleeve top is tapped with weight, retaining gland is pressed into, the annular ditch of retaining gland is fitted compression with ball
In ball, the screw thread of ball dump bolt, bolt can not turn, installation with anti-return nut；
When c. dismantling, the extracting tool of anti-disassembling nut is taken, gripper the ladder of retaining gland is gripped in into along upper, jackscrew is withstood on
On bolt, turn jackscrew removes retaining gland, then rotates nut, and Bolt dismantling is finished.
Compared with prior art, the beneficial effects of the invention are as follows：
Anti-disassembling nut and its matched special purpose tools, it is simple to operate, quick, operating efficiency is improved, staff is reduced
Labor intensity, improves the fixed assets rate of recovery and line construction, the efficiency of maintenance.It can solve the problem that transmission line construction, maintenance are real
Border work problem.
