Novel portable and scalable climbing ladder and preparation method thereof

Abstract

The invention discloses a novel telescopic crawling ladder convenient to move and a manufacturing method thereof. The crawling ladder comprises a supporting base and a crawling ladder body. The supporting base is an inverted-T-shaped base, universal wheels are arranged at the three protruding ends of the base correspondingly, and locking devices are arranged on the universal wheels. The crawling ladder body is vertically erected in the center of the inverted-T-shaped base and divided into an inner frame section and an outer frame section. The outer frame is a fixed crawling ladder section, the bottom of the outer frame section is fixed to the inverted-T-shaped base, and three inclined struts corresponding to the three protruding ends of the inverted-T-shaped base are arranged at the top of the outer frame section to from a triangle support. The inner frame section is a telescopic crawling ladder section, and the bottom of the inner frame section is adjustably mounted on the fixed crawling ladder section through buckles. According to the novel telescopic crawling ladder, the sleeving-connection mode of the triangle support, the inner frame section and the outer frame section is flexibly used, the height is adjustable while the strength of the crawling ladder is ensured, the novel telescopic crawling ladder is suitable for the environments with broad space and high operation height, convenient to move, capable of being independently used without depending on other supports and low in technical requirement, manufacturing can be completed by common welders, quite common galvanized steel pipes are used as materials, material taking is convenient, and the application range is broad.

Description

technical field [0001] The invention relates to the technical field of ladders, in particular to a novel ladder that is easy to move and expandable and a preparation method thereof. Background technique [0002] During the construction process, the traditional ladder needs to rely on a certain reliable point before it can be erected and used, and its climbing height is generally within 3m. When there is no reliable object around in a relatively large space, it needs to be climbed higher However, the cost of electric lifting platform vehicles and scaffolding is high, the scaffolding takes up a lot of space, and it takes a long time to install and dismantle, which may affect other construction operations and other factors. Although some mobile ladders that can be climbed independently at present, the height of climbing is less than two meters. Therefore, need badly a kind of novel ladder tool. Contents of the invention [0003] The purpose of the present invention is to pr...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a new type of climbing ladder that is easy to move and expandable and its preparation method, which can make up for the defects of the climbing height of the moving ladder and the fact that the climbing ladder cannot be placed in isolation in the prior art, as well as the high cost of the electric lifting platform vehicle or scaffolding and the occupation of the scaffolding. Large space, long installation and dismantling time, there are problems affecting other construction operations
