An electric climbing ladder that realizes rapid climbing under dangerous conditions of underground operations

Abstract

The invention belongs to the technical field of climbing ladders, and specifically relates to an electric climbing ladder that realizes rapid climbing under dangerous conditions of underground operations, including a ladder body; multiple groups of the ladder bodies are stacked and slidingly connected; the inner side walls of the middle part of the ladder body are fixed There is an electric cylinder; the side wall of the electric cylinder is fixed with a protective shell; the protective shell is sleeved on the ladder body; the inner side wall of the top of the protective shell is slidingly connected with a sleeve; the sleeve is sleeved on the output of the electric cylinder On the end; the motor is protected by a protective shell and a casing, and when the electric cylinder is extended, the casing will protrude from the inside of the protective shell to protect the output rod of the electric cylinder and protect it. The setting of the shell and casing protects the electric cylinder from being easily affected by small stones from the outside. When small stones and sand fall in the well, avoid direct contact with the electric cylinder, which may affect the normal operation of the electric cylinder. The stability of the ladder body when it is unfolded.

Description

technical field [0001] The invention belongs to the technical field of climbing ladders, and in particular relates to an electric climbing ladder which realizes rapid climbing under dangerous conditions of underground operations. Background technique [0002] Ladder is a tool that is often used in daily life and construction scenes. There are also ladders in various states, such as folding ladders, telescopic ladders, etc. [0003] There are also some technical solutions about climbing ladders in the prior art. For example, a Chinese patent with application number 2016110189964 discloses a climbing ladder mechanism for inspection wells, including a ladder, one of which is arranged at intervals up and down along one side wall of the inspection well. Pre-embedded bracket 1 and at least two pre-embedded brackets 2. The top of the ladder has a bent part for hooking on the well edge of the inspection well. Inoue. [0004] In the current prior art, during the use of the electric...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, it is solved that because the underground ladder is in a dark and humid environment with a lot of gravel for a long time, during the standby process of the electric ladder, there will be falling rocks and gravels inside the inspection well. When it collides with the electric cylinder on the ladder, the electric cylinder will be damaged. In severe cases, the electric cylinder cannot be used normally. The invention proposes an electric climbing ladder that realizes rapid climbing under dangerous conditions of underground operations.
