Description

Technical Field

[0001] This utility model relates to the field of ladder technology, and more specifically to a stackable ladder. Background Technology

[0002] A ladder is a tool used to help people work at heights. Existing ladders include straight ladders, A-frame ladders, telescopic ladders, and cage ladders. Ladders are used during the assembly of work frames to allow personnel to reach certain heights for installation, maintenance, and inspection.

[0003] Existing aerial work platforms have a simple structure, generally consisting of a steel frame with stairs installed inside to allow workers to access the platform for work. Partitions are also installed inside the platform for workers to stand and perform tasks. For example, there is an aerial work platform with the existing technology publication number CN222140829U.

[0004] However, the above-mentioned existing technologies still have the following problems when in use: When using traditional ladders, the large number of devices next to the main assembly frame will affect the assembly and stability of the ladder. At the same time, since the ladder needs to change with the height of the main assembly frame, it is very time-consuming and laborious for workers to carry tools up the ladder. Using hoisting equipment for some small tools is very costly. Based on this, this utility model provides a stackable ladder with high stability and hoisting function. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a stackable ladder. By designing the ladder components to be stackable, the height of the ladder can be changed, thus increasing its applicability. At the same time, the stability of the ladder can be improved by using steel wire ropes and connectors. Furthermore, a winch that can move up and down is provided to facilitate the hoisting of items to different heights, greatly saving manual handling time and improving construction efficiency, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stackable ladder, comprising multiple sets of ladder units, each set of ladder units comprising multiple ladder components stacked sequentially from bottom to top, each ladder component comprising a base, the top of the base being connected to a top plate via multiple enclosures, two staircases connecting the bottom of the top plate and the top of the base, each top plate and each base having at least one passageway, each base being fixedly provided with a lifting bracket, the lifting bracket being connected to a steel wire rope for connecting to the ground to improve the stability of the base, each ladder component also being connected with a protective component, and the ladder component also being provided with a hoisting mechanism.

[0007] In a preferred embodiment, each base is fixedly provided with a connector, which is located below the lifting bracket. The connector is detachably connected to the assembly frame to further improve the stability of the ladder during use.

[0008] In a preferred embodiment, the protective component includes a protective fence that is detachably installed on top of the base at the very top. When workers walk to the top of the ladder, the protective fence can provide protection and prevent workers from accidentally falling.

[0009] In a preferred embodiment, the hoisting mechanism includes a fixed plate, which is detachably installed in an opening on the top plate. An installation plate is slidably mounted on the fixed plate, and a winch is fixedly mounted at the bottom of the installation plate. A hoisting rope is wound on the winch. By using the winch to wind up the hoisting rope and tying the bottom end of the hoisting rope to a ground object, the ground object can be automatically hoisted to different heights, making it convenient for workers to use.

[0010] In a preferred embodiment, each fixed plate has a groove on the side near the stairs, and each mounting plate has a slider fixed on the side near the fixed plate. The slider is slidably disposed in the groove to assist the workers in fixing the mounting plate.

[0011] In a preferred embodiment, each top plate is fixedly provided with a wire roller at its bottom, and each mounting plate is provided with a storage groove at its top. A pull rope is placed in the storage groove, and one end of the pull rope is fixed to the inner wall of the storage groove.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model designs the ladder components as stackable, which allows for arbitrary stacking and adjustment of the ladder height. It is simple to construct and has a wide range of applications. Furthermore, by using steel wire ropes and connectors, the firmness between the ladder and the main frame and the ground can be improved, thereby enhancing the stability of the ladder unit.

[0014] 2. By setting up a winch that can move up and down and working with a hoisting rope, it is convenient to move items to different heights, which can greatly save the time of manual handling and thus improve construction efficiency. In addition, by using the pull rope and the roller together, the height of the winch can be manually adjusted, making it faster to use. Attached Figure Description
