Problems solved by technology

[0011] To sum up, the above-mentioned current methods of climbing work have their own advantages and disadvantages: aerial work vehicles, lifting platforms and scaffolding are relatively safe, but very inconvenient and uneconomical; ordinary escalators are easy to use and economical. Sex is good, but there is a big security risk

Embodiment 1

[0036] Such as figure 1 As shown, the special climbing ladder for casing maintenance includes an escalator 1, a soft contact piece 201 arranged on the upper part of the escalator 1 that can match the casing 5, and an angle increasing device arranged at the lower part of the escalator 1 for increasing the climbing angle of the escalator 1 3; the angle increasing device 3 includes an angle increasing frame 301, a support foot 302 located at the bottom of the angle increasing frame 301, a software piece 303 located on one side of the angle increasing frame 301, and one side of the angle increasing frame 301 The connecting side of the escalator 1 connected to the lower part of the escalator 1, the side opposite to the connecting side of the escalator 1 on the angle increasing frame 301 is the matching side of the casing 5, and the matching side of the casing 5 is provided with the soft part 303, The outer surface of the soft part 303 is an arc-shaped inner concave surface that ca...

Embodiment 2

[0045] The same as the first embodiment will not be repeated, the difference is: in order to improve the safety of the work, the upper and middle parts of the escalator 1 are equipped with telescopic fixing belts 4 that can bind the escalator 1 to the climbing object , the fixed belt 4 is connected and fixed with the escalator 1 through a horizontal connecting rod. The telescopic fixing belt 4 binds the escalator 1 on the casing 5 to avoid slipping away. After the telescopic fixing belt 4 is tied on the casing 5, no other personnel are required to hold it by hand to prevent it from toppling over and reduce labor costs.

[0046] In order to improve the installation strength of the fixing belt 4 without affecting the normal use, the escalator 1 is a telescopic escalator 1, wherein the upper fixing belt 4 is located at the crossarm position 500mm-700mm away from the top of the escalator 1, and the fixing belt 4 in the middle The belt 4 is located at the cross arm position 9000mm-...

Abstract

The invention relate to a climb ladder, in particular to a climb ladder special for casing pipe overhauling. At present, the climb operation means cannot simultaneously have safety, convenience and economy. The climb ladder special for casing pipe overhauling comprises a ladder body, a flexible contact capable of being matched with a casing pipe and arranged on the upper portion of the ladder body and an angle increasing device arranged on the lower portion of the ladder body and used for increasing the climb angle of the ladder body. The angle increasing device comprises an angle increasing frame, supporting feet arranged at the bottom of the angle increasing frame and a flexible piece arranged on one side of the angle increasing frame. One side of the angle increasing frame is a ladder body connecting side connected with the lower portion of the ladder body. The side, opposite to the ladder body connecting side, of the angle increasing frame is a casing pipe matching side. The casing pipe matching side is provided with the flexible piece, and the outer side face of the flexible piece is an internally-concave arc face capable of being matched with the casing pipe. According to the technical scheme, the flexible contact is arranged on the upper portion of the ladder body, a casing pipe porcelain bottle is prevented from being hit, the angle increasing device is additionally arranged, the angel between the ladder body and the casing pipe is increased, stability of the ladder body is improved, the possibilities of side turn and back turn are reduced, and safety, convenience and economy are simultaneously achieved.

Description

technical field [0001] The invention relates to a climbing ladder, in particular to a special climbing ladder for bushing maintenance. Background technique [0002] In the process of overhauling, testing and maintaining the main transformer medium-voltage bushings of 500kV substation and 220kV GIS bushings, it is often necessary to remove the terminals. Transformer bushing structure such as Figure 5 As shown, since the sum of the height of the transformer bushing and the riser has reached 3.5 meters, it is necessary to carry out climbing operations. The current means of climbing operations mainly include: [0003] 1. Use an aerial work vehicle. The aerial work vehicle is flexible, safe and reliable. However, its disadvantages are that complicated work plans, organizational measures, and technical measures need to be compiled, and personnel with aerial work certificates and crane command certificates are required to supervise. The cost of dispatching vehicles and human re...
