Description

Technical Field

[0001] The invention relates to the technical field of safety ladder cages, and in particular to a movable and adjustable multifunctional safety ladder cage. Background Art

[0002] Traditional safety measures for aerial work and up and down traffic at docks only use safety nets, safety ropes, temporary ladders and other measures, with a very low safety factor, and the service life of safety nets and safety ropes is very short and they are very easy to wear. In addition, there are few construction focus points, making it difficult for operators to carry out construction. When using temporary ladders and other safety measures for aerial work and up and down traffic, although the safety factor is improved to a certain extent and it is less prone to damage, the temporary ladder can only provide a fixed temporary passage, which is only a drop in the bucket for the large-scale construction of the entire dock. A large number of temporary ladders or the use of cranes to change positions are required to solve this type of problem. Moreover, this type of temporary construction ladder is generally a finished ladder prefabricated in the factory, and the dimensions of the ladder, such as the length of the ladder and the angle of the pedal, are fixed. Therefore, it can only be used within a fixed space range, a fixed angle range, and a fixed distance range, and the use environment is limited.

[0003] For example, Chinese patent CN108783928A discloses a mobile ladder for book management, including a storage cart, a ladder mechanism, a book box, etc., which can realize the up and down and overall horizontal movement of the storage mechanism, thereby improving the efficiency, convenience and safety of book sorting by staff.

[0004] For example, Chinese patent CN105133858A discloses an adjustable safety construction ladder, which belongs to the field of construction ladders in the loading and unloading industry. It includes a counterweight box, a fixed cantilever column, a cantilever top pin, a movable ladder positioner, a movable cantilever column, a cantilever beam, a safety belt hanging ring, etc. It can be adjusted to different heights and angles to ensure the personal safety of construction workers performing aerial operations. It uses detachable parts, and is quick and easy to install, transport, and use.

[0005] Moreover, the above-mentioned ladder can only be used in construction environments such as from low to high, straight up or straight down, diagonally up or diagonally down, and horizontally, but cannot be used in usage environments such as crossing obstacles and moving in space.

[0006] Based on this, the present invention designs a movable and adjustable multifunctional safety ladder cage to solve the above problems. Summary of the invention
