Described angle steel gripping mechanism includes angle steel standing screw and angle steel fixes fixture block, and angle steel fixes fixture block and is set in angle
It is on steel standing screw and spacing by nut.
The application method of the hard hard ladder of ladder afterbody stationary fixture fastening insulation of insulation, comprises the following steps：
1) the hard ladder front end of insulation is hooked on wire；
2) the angle steel gripping mechanism of two hard ladder afterbody stationary fixture rear ends of insulation is separately fixed at the X-type of high tension electric tower
On angle steel, both sides angle steel gripping mechanism is placed in the same level of X-type angle steel crosspoint top, angle steel standing screw and the two of angle steel
Right-angle side is fitted, and fastens angle steel fixing card block, fixes fixture；
3) two square terraced pipes of the hard ladder that insulate are put into the ladder tube fixer of both sides, and are fastened by screw rod and nut, made
Level is kept after the hard ladder of insulation and tower body fastening；
4) the hard ladder stability of insulation is checked；
5) after end-of-job, the hard ladder afterbody stationary fixture of insulation is removed in reverse order.
Compared with prior art, the beneficial effects of the invention are as follows：
Present clip small volume, it is lightweight, formed between the hard ladder of level insulation and the crosspoint of X-type angle steel after fastening
The triangle of stabilization, it is ensured that the fixed stability of the hard ladder of insulation.While enhancing security, the work of operating personnel is also mitigated
Intensity.Comfortableness, the security for entering powered position operation along the hard ladder of insulation can further be improved.It is rational in infrastructure, practicality
By force, with application value.
