Abstract

The invention discloses a crawling ladder. The crawling ladder comprises a cover plate which is arranged at the top of a stand column, wherein a first hoop is arranged along the side wall of the stand column; the cover plate is further provided with a lifting hook which is connected with the first hoop and is used for fixing the first hoop; and the first hoop is connected with a ladder rod for a worker to climb to the top of the stand column. The cover plate comprises at least three rod pieces which are connected end to end to form a sealed plane pattern and are fixed at the top of the stand column. The front and tail ends of any rod piece are located outside the range of the top of the stand column; and the lifting hook is arranged at the mutually-connected connection part of the two rod pieces. The first hoop is located at the position close to the top of the stand column; and a second hoop, which is connected with the ladder rod, is further arranged at the position close to the bottom of the stand column and along the side wall of the stand column. The first hoop and the second hoop are separately arranged, and are connected by a bolt to form a whole body and are wound on the side wall of the stand column. The ladder rod comprises an upper ladder rod and a lower ladder rod; and the upper ladder rod and the lower ladder rod are connected through a connection plate and a bolt. The crawling ladder can prevent from shaking so that the reliability is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a climbing ladder. Background technique [0002] With the rapid development of my country's economic construction, the market demand for various types of ladders is increasing. [0003] At present, the transmission lines with the highest voltage level in my country are 1000kV UHV AC transmission lines. Due to the high voltage level and the huge tower body, in order to stabilize the tower, large-diameter concrete foundation columns are generally used for the base of the column; in some areas, the column is affected by factors such as terrain, resulting in the distance between the top of the column and the ground exceeding More than two meters. As a result, it is often necessary to use the ladder bar when performing maintenance and other work on the column. [0004] In the prior art, embedded ladder poles are usually used; that is, the two ends of the ladder poles...
