Description

Technical Field

[0001] The present invention relates to a building climbing ladder, and more particularly to a steel structure safety climbing ladder device. Background Art

[0002] With the improvement of the building construction technology level, steel structure buildings have gradually become one of the main forms of urban building types in our country; at the same time, due to their advantages such as high strength and light weight, they are widely used in building shape shaping and the main structure of public buildings. During the construction of steel structures, the construction is usually carried out by prefabricating steel columns and steel beams in the factory and then installing them on site, so a large number of high-altitude operations are inevitably required.

[0003] During the construction process of buildings, on the steel structure, in order to facilitate the workers to go up and down, a climbing ladder structure needs to be used. The ordinary climbing ladder structure does not have a protection function, and it is very easy to cause workers to fall and have accidents during the process of workers going up and down.

The four corners of the ladder 1 are fixed in sequence to fix the ladder 1.

[0034] When a worker falls, due to the weight and falling speed of the worker being relatively fast, the safety belt 6 will pull the connecting belt 710 as the falling speed of the worker. Thus, the gravity at the moment of falling will pull the elastic block 711 out of the connecting shell 707, thereby continuing to pull the connecting belt 710 to move quickly. When falling 0.5 m, the clockwork spring 709 will be tightened, causing the winding shaft 701 to rotate quickly. In this way, the centrifugal force causes the connecting block 704 to displace outwards. The first engaging teeth 706 on the connecting block 704 are engaged with the second engaging teeth 708, and the winding shaft 701 stops rotating, thus preventing the worker from falling and preventing the impact force caused by the worker's sudden stop, and giving a certain buffer distance.

[0035] When the worker falls, the pulling causes the winding shaft 701 to stop rotating, pulls the slider 7, the slider 7 pulls the limit plate 9, the limit plate 9 compresses the first spring 14, the limit plate 9 approaches the guide rail, and the limit teeth 10 on the limit plate 9 are clamped on the first rack 8 outside the slide rail 5, realizing the stopping of the slider 7, thereby preventing the worker from falling.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
