However, in some special cases, operators often need to enter these places for maintenance or other emergency operations
In the prior art, since there are no dedicated working passages in these places, operators generally use temporary tools such as stepladders, straight ladders, and scaffolds for maintenance and other operations. The safety factor is not high, so it is not suitable for nuclear power plant operations; the vertical ladder is not flexible, the applicable drop range is limited, and it is inconvenient to carry, so it is not suitable for emergency operations with high drop ranges; Suitable for pools, corridors and other construction sites with limited space

Embodiment Construction

[0019] In order to describe the technical solution, structural features, and achieved technical effects of the present invention in detail, the following will be described in detail in combination with specific embodiments and accompanying drawings.

[0020] see figure 1 , the present invention provides a combination ladder, which is suitable for being arranged on a leaning body for climbing. The combination ladder comprises at least two ladder modules which are detachably connected from head to tail and at least two ladder modules are rotatably connected. In this embodiment, the combined ladder includes three ladder modules, the ladder module 1 at the top, the ladder module 2 at the middle and the ladder module 3 at the bottom, and the ladder modules are rotatably connected. In this embodiment, the head of the ladder module 2 is connected to the tail of the ladder module 1 through a hinged structure or other connections that allow the ladder modules 1 and 2 to rotate relative...

Abstract

The invention provides a combined crawling ladder. The combined crawling ladder can be arranged on a backrest body so that climbing is convenient. The combined crawling ladder comprises at least two crawling ladder modules of which the head and tail can be detachably connected. The crawling ladder module is provided with a supporting part extending to the backrest body so that the crawling laddermodule is supported on the backrest body. The top end of the crawling ladder module in the top is provided with a hanging part bent to the backrest body so that the crawling ladder module can be suspended to the top surface of the backrest body. The hanging portion is provided with a top fixing part fixed to the top surface of the backrest body. The bottom end of the crawling ladder module at thebottom is provided with a bottom fixing part fixed to the crawling ladder module. The combined crawling ladder is easy to assemble, has a high safety factor and is suitable for various drop ranges.

Description

technical field [0001] The invention relates to a climbing ladder, in particular to a combined climbing ladder. Background technique [0002] Culverts, pools, pits, corridors, etc. are relatively hidden construction locations of nuclear power plants. These construction locations are inconvenient to enter and exit, and basically no one enters them at ordinary times. However, in some special cases, operators often need to enter these places for maintenance or other emergency operations. In the prior art, since these places do not have dedicated working passages, workers generally use temporary tools such as ladders, straight ladders, and scaffolds for maintenance and other operations. The safety factor is not high, so it is not suitable for nuclear power plant operations; the vertical ladder is not flexible, the applicable drop range is limited, and it is inconvenient to carry, so it is not suitable for emergency operations with high drop ranges; It is suitable for construct...
