a folding ladder

Abstract

The invention relates to a folding climbing ladder, which is composed of multi-layer pedals and multiple sets of folding mechanisms. The folding mechanism is composed of a rotating connecting rod and a group of folding connecting rods. A group of folding connecting rods is composed of a long connecting rod and a short connecting rod; Two pivots at the corners. The present invention can be suspended and installed at the bottom of the carriage without taking up space on the carriage; the deployment and erection are not affected by the terrain, and are safe and stable; the operation is convenient, and rapid deployment and retraction can be realized; the degree of shrinkage is high, and it will not appear on the appearance of the carriage after shrinking form larger protrusions.

Description

technical field [0001] The invention belongs to the field of ground support equipment, and relates to a folding climbing ladder, in particular to a vehicle-mounted hanging folding climbing ladder. Background technique [0002] The missile ground vehicle launch system includes various mission platforms. Due to the consideration of military off-road performance, this type of platform often has a high chassis, and various functional modules erected on the chassis are generally higher than the reach of ordinary people. Auxiliary operation of equipment such as ladders. Existing climbing ladders mainly include two types of H-shaped ladders and wooden inclined ladders, and the following problems are prone to occur in practical applications: [0003] 1) These two types of ladders and vehicle-mounted platforms are separated and require special storage space; [0004] 2) The H-shaped ladder is a temporary erection type, and its stability and safety are difficult to guarantee due to ...

AI Technical Summary

Problems solved by technology

[0003] 1) These two types of ladders and vehicle-mounted platforms are separated and require special storage space;

[0004] 2) The H-shaped ladder is a temporary erection type, and its stability and safety are difficult to guarantee due to the influence of the position environment and vehicle-mounted equipment;

[0005] 3) Most of the existing H-shaped ladders are retractable, but their deployment and storage are inconvenient and time-consuming;

[0006] 4) The wooden inclined ladder is a platform-type climbing ladder, and its stability is better than that of the H-shaped ladder. However, its structure is bulky and bulky, and it needs to occupy a large vehicle space, which affects the placement of task equipment. It is also very inconvenient to lay it in place, and it takes a lot of money manpower
