Deng severe maintenance construction requirement.
The present invention is improved to original insulated flexible ladder, using single pendulum pendency adjusting method, in the bottom of rope ladder head with list
Point manner fixes a terraced head and swings undercarriage component, realizes two side rollers of hook stress simultaneously, good contact is kept with wire,
And swinging undercarriage component can keep rope ladder perpendicular to the ground all the time, make to remain steady shape in the insulated flexible ladder course of work
State, prevent the generation of hook and wire break-off, meanwhile, install back-up protection pulley additional in the center of hook two-arm,
Improve the security of livewire work personnel.
After insulated flexible ladder ladder head improves, its major advantage has：
1st, the security of livewire work work is enhanced, it not only eliminates existing hook, and have can in livewire work work
The potential safety hazard of wire can be departed from, while a backup rope, pole are added during operating personnel climbs insulated flexible ladder
It is big to improve overall operation level of security.
2nd, greatly mitigate the labor intensity that livewire work personnel climb insulated flexible ladder process, reduce physical demands, carry
Operating efficiency in high workload.
3rd, improving cost is cheap, simple and easy to do, and attended operation is simple.
It is improved, it can greatly mitigate the labor intensity that livewire work personnel climb insulated flexible ladder process, reduce muscle power
Consumption, the operating efficiency in work is improved, and largely enhance the security of livewire work work.
In a word, a kind of livewire work single pendulum adjustable type rope ladder head device of the present invention, is that a kind of hot line maintenance is soft
Terraced method enters the instrument of highfield.The rope ladder head device is by hook block component, single pendulum adjusting part, terraced head chassis body three
It is grouped into.The device makes hook block component equal with wire holding good contact, stress all the time using single pendulum pendency regulation method
Weighing apparatus, meanwhile, the device sets up one-way brake tackle arrangement as personnel's fall arrest second protection at the suspension ring of terraced head bottom, climbs
When can remain that rope ladder is perpendicular to the ground.The development of the device, which solves, has rope ladder hanging point stress when the wire gradient is larger
Safety problem caused by stability difference caused by unbalanced and deviation wire, reduces the labor intensity of operating personnel, ensures
The personal safety of operating personnel, improve livewire work service work efficiency.The present invention is simple in construction, easy to operate, and safety is high
Effect.
More than, only presently preferred embodiments of the present invention, the practical range of the present invention is not limited only to, it is all according to the scope of the invention
The equivalence changes done of content and modification, all should be the technology category of the present invention.
