Description

Technical Field

[0001] The invention relates to the technical field of climbing ladders, in particular to a foldable climbing ladder. Background Art

[0002] In various constructions, high-altitude installation is very common, especially high-altitude installation on the wall, which will appear in various constructions. The climbing tool often used for this kind of high-altitude installation is the ladder, which is generally a retractable aluminum alloy ladder. The climbing ladder can greatly facilitate people to use it for high-altitude operations.

[0003] The climbing ladder disclosed in the Chinese invention patent application publication specification CN103573179A has two wheels that do not touch the ground to ensure the stability of the ladder and is safe to use. The outermost ends of the two wheels should extend a portion of the ladder body in parallel. When moving the ladder, the ladder body is tilted in the direction in which the wheels extend, and the ladder can be moved by the wheels extending out of the body. The movement is convenient and labor-saving. However, it is difficult to transport the tools needed by the workers to the top of the ladder during use. A special person is required to deliver them, or the workers have to constantly take them up and down, which greatly increases the labor intensity of the workers. The tools are prone to fall during the delivery process, affecting the safety of the workers. After use, the climbing ladder is difficult to collect due to its large size, and the climbing ladder can only be used as a ladder, which occupies a large space and has low practicality. Therefore, a foldable climbing ladder is proposed to solve this problem. Summary of the invention
