DETAILED DESCRIPTION

[0017] Embodiment 1

[0018] As shown in the figure: Figure 3 and Figure 4 The embodiment provides a ladder cage that can be assembled to solve the problem that the non-detachable ladder cage is placed horizontally in the construction site, occupies a large site space, and cannot be flexibly adjusted in size according to the underground construction depth, and only large size ladder cages can be replaced.

[0019] The assembled ladder cage is composed of several stacked module ladders 2, and adjacent module ladders 2 are connected by fasteners. The modular design allows the ladder cage to flexibly increase or decrease the number of module ladders 2 according to the change of construction depth, adapting to different construction needs. Through simple fastener connection, workers can quickly complete the splicing of the module ladders 2, reducing installation time and labor cost.

[0020] When assembling the ladder cage, adjacent module ladders 2 have a 180° angle difference to achieve the alternating appearance of adjacent steps 25 between the upper tread 22 and the lower tread 23. This staggered layout not only saves vertical space, but also provides a more reasonable passage path, avoiding congestion when personnel go up and down.

[0021] Specifically, as shown in Figure 3 , the module ladder 2 includes a frame body 21, an upper tread 22, a lower tread 23, and a step 25. The frame body 21 is in a cuboid frame structure, which ensures the strength and stability of the frame body 21, and remains unchanged even under heavy load.

[0022] The upper tread 22 and the lower tread 23 are separately arranged at the upper and lower ends of the frame body 21, and the upper tread 22 and the lower tread 23 are staggered. The step 25 is installed between the upper tread 22 and the lower tread 23.

[0023] A plurality of mounting holes are formed in the frame body 21 for fastener connection between adjacent frame bodies 21. The design of the mounting holes makes the connection between the module ladders more secure and can be expanded or disassembled in a simple way, facilitating transportation and storage.

[0024] In summary, the uniform mounting hole position and size standard of the module ladder 2 enable seamless connection of module ladders produced in different batches, improving the versatility and interchangeability of the equipment.

[0025] As shown in Figure 3 and Figure 4 , the upper tread 22 and the lower tread 23 have the same structure. The upper tread 22 includes a plate body 221, a bracket 222, a lower ladder end block 223, and an upper ladder end block 224. The bracket 222 is connected to the frame body 21 by a fixed plate 225, the plate body 221 is installed on the bracket 222, the lower ladder end block 223 and the upper ladder end block 224 are installed on the bracket 222, one end of the step 25 is installed on the upper ladder end block 224 of the upper tread 22, and the other end is installed on the lower ladder end block 223 of the lower tread 23.

[0026] As shown in Figure 3As shown, the module ladder 2 further comprises a protective railing 24 installed on the frame body 21 and / or the step ladder 25. The protective railing 24 provides a firm gripping point and a physical barrier, effectively preventing workers from falling when climbing up and down the ladder cage. This design can significantly improve work safety and efficiency in various construction environments.

[0027] Embodiment 2

[0028] This embodiment is based on the module ladder 2 provided in Embodiment 1, and provides an assembled lifting ladder cage to solve the problem that the expandable standard fixed ladder cage cannot match the changing construction depth due to its standard size limitation.

[0029] As shown in Figure 1 and Figure 2 , an assembled lifting ladder cage comprises a depth compensation truss 1 and a plurality of module ladders 2 provided in Embodiment 1.

The output end of the depth compensation truss 1 is connected to the module ladder 2 located in the lowermost layer.

[0030] As shown in Figure 2 , the depth compensation truss 1 comprises a placement frame 11 and electric hoists 13. The placement frame 11 forms a lowering channel inside for accommodating the module ladder 2. A plurality of electric hoists 13 are installed on the placement frame 11, and the output end of the electric hoist 13 is connected to the module ladder 2. In order to facilitate the connection of the output end of the electric hoist 13 to the module ladder 2, the output end of the electric hoist 13 is provided with a hook, and the lower end structure of the frame body 21 is provided with a lifting ring 26.

[0031] The size of the lowering channel of the placement frame 11 matches the length and / or width of the module ladder 2. The placement frame 11 is provided with a plurality of limiting blocks 12, which are in contact with the module ladder 2 to limit the position of the module ladder 2 in the lowering channel. The placement frame 11 is made of an I-beam, and the limiting block 12 is a load block that is slidably arranged on the I-beam. A locking bolt is threadedly installed on the load block, and the locking of the load block at a specified position on the I-beam can be achieved by adjusting the locking bolt, thereby limiting the module ladder 2 in the lowering channel.

[0032] In summary, the utility model discloses in use, first depth compensation truss 1 is stably arranged on the ground building base, then according to the construction needs, with hoisting device, one module ladder 2 is transferred and placed in the lower passageway of frame 11, then the hook of electric hoist 13 output end is connected on the lifting ring 26, then the chain of electric hoist 13 is slowly lowered and module ladder 2 is taut.If the construction environment needs deeper ladder cage, hoisting device can be used to continuously staggered new module ladder 2 on the module ladder 2 of connecting lifting ring 26, and adjacent module ladder 2 is connected by using fastener.If the ladder cage needs to be deeper, electric hoist 13 can adjust the space height of module ladder 2 according to the on-site situation, and the adjustment process can compensate the difference between the modular size and the on-site demand.In this way, the topmost module ladder 2 and the ground will appear the difference, and the difference needs other ladders to compensate, but the ground sets up compensation ladders than the safety and convenience of the foundation pit set up is better.
