Abstract
Description
Technical Field
[0001] This utility model relates to a ladder safety cage, specifically a ladder safety cage that is easy to assemble. Background Technology
[0002] Traditional ladder cages are assembled on-site by welding. A traditional maintenance ladder section consists of ladder arms, supports, and rungs. During installation, the angle steel supports are first welded to the wall beams, and any damaged coating areas are painted. Next, the perforated wall panel is inserted through the angle steel support, and the other end of the support is welded to the angle steel ladder arm and painted. After installation, the perforations in the wall panel need to be sealed and waterproofed. However, practical experience has shown that due to a shortage of skilled welders, assembly efficiency is significantly reduced. Therefore, improvements to existing ladder cages are necessary. This invention designs a ladder cage assembled using bolts. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a climbing ladder cage that is easy to assemble. It has a reasonable structural design, is easy to assemble, and is easy and smooth to disassemble. After disassembly, it occupies little space, is easy to transport and store, and is highly practical.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a ladder and cage for easy assembly, comprising a ladder and a cage. The cage is bolted to the upper outer side of the ladder. The ladder includes ladder arms and crossbars. The ladder arms are vertically arranged, and crossbars for climbing are evenly distributed between the ladder arms from bottom to top. The cage includes guardrails and connecting plates. Multiple guardrails are bolted to multiple vertical connecting plates. The guardrails include a central arc-shaped section and two side arc-shaped sections. The two ends of the central arc-shaped section are connected to the two side arc-shaped sections respectively. The two side arc-shaped sections are bolted to the ladder arms. The diameter of the central arc-shaped section at the bottom is larger than the diameter of all the upper central arc-shaped sections. The ladder arms are made of channel steel.
[0005] Preferably, the ladder is fixed to the equipment or wall by two ladder fixing plates.
[0006] Preferably, the bottom of the ladder arm is fixed with a foot by bolts, nuts and washers, and the foot is made of angle steel.
[0007] Preferably, the crossbar is made of round steel and has anti-slip texture.
[0008] Preferably, the ladder arm has multiple bolt holes evenly distributed from top to bottom, and the ladder arm is tightened and fixed to the arc-shaped parts at both ends of the cage by bolts through the bolt holes.
[0009] Preferably, the cage is made of flat steel.
[0010] Preferably, all bolts are square neck bolts.
[0011] The beneficial effects of this utility model are as follows: The ladder and cage, as well as the guardrails and connecting plates of the cage, all utilize square neck bolts, replacing traditional welding with bolt connections. This eliminates the need for complex welding or special tools, greatly simplifying the installation process. The modular design allows for assembly and disassembly of components as needed, improving flexibility. The cage design provides comprehensive protection, especially effective in preventing falls during high-altitude operations. The anti-slip texture on the crossbars increases friction during climbing, reducing the risk of slipping. Angle steel feet at the bottom of the ladder arms enhance the overall stability of the ladder. The cage uses a flat steel structure, strengthening its strength and durability. The ladder can be fixed to various equipment or walls using ladder fixing plates, making it widely applicable. Multiple bolt holes on the ladder arms allow for adjustment and fixation of the cage according to actual needs. All connections are bolted, facilitating future maintenance and replacement. The modular design allows damaged parts to be replaced individually, reducing maintenance costs. Attached Figure Description

[0019] Reference Figure 1-5The specific embodiment adopts the following technical solution: an easy-to-assemble climbing ladder cage, including a climbing ladder 1 and a cage 2. The cage 2 is fixed to the upper outer side of the climbing ladder 1 by bolts. The climbing ladder 1 includes ladder arms 3 and crossbars 4. The ladder arms 3 are vertically arranged, and crossbars 4 for climbing are evenly distributed between the ladder arms 3 from bottom to top. The cage 2 includes guardrails 5 and connecting plates 6. Multiple guardrails 5 are connected and fixed to multiple vertical connecting plates 6 by bolts. The guardrails 5 include a middle arc-shaped section 51 and two side arc-shaped sections 52. The two ends of the middle arc-shaped section 51 are respectively connected to the two side arc-shaped sections 52. The two side arc-shaped sections 52 are connected to the ladder arms 3 by bolts. The diameter of the middle arc-shaped section 51 at the bottom is larger than the diameter of all the middle arc-shaped sections at the top.
[0020] It is worth noting that the ladder 1 is fixed to the equipment or wall by two ladder fixing plates 7.
[0021] It is worth noting that the bottom of the ladder arm 3 is fixed with a foot 9 by bolts 8, nuts and washers, and the foot 9 is made of angle steel.
