Description

Technical Field

[0001] This utility model relates to the field of construction materials technology, and in particular to a safety ladder cage base fixing device. Background Technology

[0002] In various scenarios such as construction, equipment maintenance, and emergency evacuation, safety ladders serve as crucial equipment for working at heights and facilitating escape. Their stability and safety directly impact the lives of workers. The installation of safety ladders requires a level bottom; however, irregularities in the ground, such as slight height differences or unevenness, can occur in real-world environments. These suboptimal ground conditions often prevent the safety ladder from achieving the desired level after installation, affecting not only user comfort but, more importantly, potentially leading to structural instability and increased safety hazards.

[0003] On the other hand, even if the initial installation of the safety cage is completed, long-term operating loads and environmental factors may cause the support structure to gradually loosen or deform. In particular, when the support column relies on a single main support without auxiliary support, its overturning resistance will be greatly reduced, and safety hazards will increase accordingly.

[0004] Therefore, it is now necessary to design a safety ladder cage base fixing device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a safety ladder cage base fixing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A safety ladder cage base fixing device includes a safety ladder cage. Fixing components are installed at the four lower corners of the safety ladder cage. Each fixing component includes a second support column. A first support column is slidably inserted into the upper end of the second support column. The first support column is connected to the lower end of the safety ladder cage. The interior of the second support column is provided with a height adjustment mechanism connected to the first support column. A base plate is fixed to the lower end of the second support column. Eight reinforcing ribs are connected between the second support column and the base plate. An auxiliary support mechanism is installed between two of the reinforcing ribs.

[0008] As a further improvement of this utility model, the first support column is fitted onto the lower end of the safety cage, and two connecting bolts are provided through the side wall of the first support column, with the connecting bolts penetrating the first support column and a connecting nut threaded onto the connecting bolt.

[0009] As a further improvement of this utility model, the height adjustment mechanism includes a threaded rod rotatably connected to the inner bottom wall of the second support column. The threaded rod passes through the lower end of the first support column and is threadedly connected to the first support column. A worm gear is fixedly sleeved on the side wall of the threaded rod. A worm is provided on the inner side of the second support column. The worm meshes with the worm gear. One end of the worm is rotatably connected to the inner wall of the second support column. The other end of the worm passes through the second support column and is fixedly connected to a rotating block. A hexagonal groove is provided on the side wall of the rotating block. A groove is provided on the side wall of the second support column. The rotating block is located inside the groove.

[0010] As a further improvement of this utility model, the auxiliary support mechanism includes an auxiliary support plate, on which a pin is provided through, the pin being rotatably connected to the auxiliary support plate, two reinforcing ribs passing through both ends of the pin and being fixedly connected to the reinforcing ribs, and a second mounting hole is provided through the auxiliary support plate.

[0011] As a further improvement of this utility model, a sealing plug is embedded inside the groove.

[0012] As a further improvement of this utility model, the base plate is provided with first mounting holes at the four corners of its upper end.

[0013] The beneficial effects of this utility model are:

[0014] By setting up a height adjustment mechanism, the height of the first support column can be adjusted. When the four corners of the safety cage are not level and there is a small height difference, adjusting the height of the first support column can provide stable installation support for the safety cage, making it more adaptable.

[0015] By setting up an auxiliary support mechanism, the second support column can be further supported, ensuring its stability and improving safety.

[0016] This utility model is equipped with a height adjustment mechanism, which can flexibly adapt to different ground height changes, provide stable installation support for the safety cage, and has better adaptability. It also has an auxiliary support mechanism, which further improves the overall structural safety, thereby effectively enhancing the safety of high-altitude operations. Attached Figure Description
