Abstract

The utility model relates to a dedicated ladder facilitating operation of 220 KV/ 66 KV in-and-out wire, which is characterized by comprising a folding ladder body, on the top of the ladder body is fixed with a hook provided with a thread locking device. By adopting the lifting method employing the ladder body instead of a rope, time and effort are saved. The top of the ladder body is provided with the hook cooperated with a metal cross arm and locked with a locking device, so that working security is enhanced. Due to the folding ladder body, the dedicated ladder is convenient to carry and use.

Description

220KV/66KV turnover wire special ladder
Technical field
The utility model relates to operation aid on tower, particularly a kind of 220KV/66KV turnover wire special ladder.
Background technology
At present, when transformer master, change both sides wire line shaft tower turnover wire are carried out operation or are safeguarded, operating personnel first utilizes rope to become in the metal cross arm that hanging ring hangs over steel tower conventionally, then be promoted to steel tower top by rope, its process is time-consuming, effort, there is potential safety hazard simultaneously, be unfavorable for carrying out smoothly of operation on tower.
Summary of the invention
The purpose of this utility model is the 220KV/66KV turnover wire special ladder that addresses the above problem, significantly improves operating efficiency and coefficient of safety in order to provide a kind of.
The technical solution of the utility model is:
A kind of 220KV/66KV turnover wire special ladder, its special character is: it has collapsible ladder body, and described terraced body top is fixed with hook, and described hook is provided with screw-threaded coupling device.
Described terraced body has two channel-section steel shape pillars and is connected to the multiple crossbeams between two pillars.
Described screw-threaded coupling device is made up of threaded post, the handle being located at the portion that holds out against of threaded post one end and being located at the threaded post other end, described in hold out against and deploy in described hook inner side.
The beneficial effects of the utility model are:
1, owing to terraced body being set as the instrument of climbing, replace rope hoisting way, time saving and energy saving;
2, coordinate with the metal cross arm of steel tower and utilize locking device locking because terraced body top is provided with hook, having strengthened operational security;
3,, because terraced body is collapsible, be convenient to carrying and use.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is folded state schematic diagram of the present utility model.
In figure: terraced body 1, pillar 101, crossbeam 102, screw-threaded coupling device 3, threaded post 301, hold out against portion 302, handle 303.
Embodiment
As shown in the figure, this 220KV/66KV turnover wire special ladder, it has the collapsible ladder body 1 that utilizes hinge 4 to connect, described terraced body 1 is made up of aluminum alloy materials, ladder body 1 has two channel-section steel shape pillars 101 and is connected to the multiple crossbeams 102 between two pillars 101, the top of two pillars 101 is fixed with metal hanger 2, and described hook 2 is provided with screw-threaded coupling device 3.Described screw-threaded coupling device 3 is made up of threaded post 301, the handle 303 being located at the portion that holds out against 302 of threaded post 301 one end and being located at threaded post 301 other ends, described in hold out against portion 302 and be placed in hook 2 inner sides.When use, first hook 2 is hooked in the metal cross arm of steel tower, then rotates the handle 303 of screw-threaded coupling device 3, make it hold out against portion 302 and closely cooperate and realize locking with metal cross arm contact-making surface.
