Specific embodiment
The present invention is described in detail with reference to the accompanying drawings of the specification, it should be noted that implementation of the invention is unlimited
In the following embodiments and the accompanying drawings.
As Figure 1-Figure 5, a kind of transformer equipment component ladder preventing mistake scrambling device, including fixed ladder 5, folding climbing ladder
6, anchor ear 3, spare tyre lifter 2, limit 1, limited post 7, lifter operating stick 8, the fixed ladder 5 are fixed on shaft tower 4 in flakes
On, the folding climbing ladder 6 is hinged on the bottom of fixed ladder 5, and the spare tyre lifter 2 is mounted on shaft tower 4 by anchor ear 3,
The rope traction end of spare tyre lifter 2 is fixedly connected with the bottom of folding climbing ladder 6, is fixed in the side of 6 bottom of folding climbing ladder
There is a limited post 7, the limit 1 is mounted on fixed ladder 5 and ipsilateral, the lifter with limited post 7 in flakes by installation axle
Operating stick 8 is adapted to spare tyre lifter 2.
The folding climbing ladder 6 includes crossbeam 10, vertical beam 11, several crossbeams 10 are fixed between two vertical beams 11, and two
The upper end of vertical beam 11 is equipped with axis hole, and the two sides of fixed 5 bottom of ladder are equipped with articulated shaft, and two vertical beams 11 of folding climbing ladder 5 pass through
