Description

Technical Field

[0001] This invention relates to the field of ladder cage technology, specifically a unit-type ladder cage with automatically adjustable height. Background Technology

[0002] With the diversification of building structures and functions, building heights are becoming increasingly diverse. During construction, standardized access ladders or other types of walkways are commonly used. Standardized ladders offer high structural strength, good stability, an attractive appearance, and reliable safety, meeting various construction safety requirements. However, traditional standardized ladders are typically 3 meters high per section, which can lead to significant height differences between the ladder entrance / exit and the floor surface, and difficulties in constructing access routes. While various height-adjustable box-type ladders exist, most rely on assembly / disassembly or manual adjustment, resulting in low automation, limited practicality, and inconvenient installation and disassembly. Summary of the Invention

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations. Example

[0024] A modular ladder cage with automatically adjustable height, such as Figure 1 As shown, the base includes a bottom frame 1, a middle frame 2 is provided directly above the bottom frame 1, the four corners of the middle frame 2 are fixedly connected to the four corners of the bottom frame 1 by four first support tubes 3, and a bottom platform 4 is fixed to one end of the bottom frame 1.

[0025] like Figure 1 , 2 As shown, it also includes a middle platform 5, which is offset from the bottom platform 4. The middle platform 5 and the middle frame 2 are slidably connected by guide rails 6. Guide rails 6 are fixed on three sides of the middle platform 5 on the middle frame 2. Grooves are provided on the three sides of the middle platform 5. The grooves are snapped to the protrusions of the guide rails 6. The guide rails 6 are wirelessly remote controlled. Under the drive of the guide rails 6, the middle platform 5 and the middle frame 2 can be automatically slidably connected.

[0026] like Figure 1 As shown, it also includes a top base, which includes a top frame 7. Each of the four corners of the top frame 7 is provided with a second support tube 8. The size of the second support tube 8 is slightly smaller than that of the second support tube 3. The four second support tubes 8 are respectively connected to the four first support tubes 3 by socketing. The bottom of each of the four second support tubes 8 is connected to the bottom frame 1 through a hydraulic lifting rod 9. The hydraulic cylinder of the hydraulic lifting rod 9 is fixed to the top of the bottom frame 1. The piston rod extends into the second support tube 8 and is fixedly connected to the bottom of the second support tube 8. The hydraulic lifting rod 9 is wirelessly remote controlled. Under the drive of the hydraulic lifting rod 9, the top frame 7 and the bottom frame 1 can be automatically slidably connected. A top platform 10 is fixed on the top frame 7. The top platform 10 is staggered from the middle platform 5.

[0027] like Figure 1 , 3 As shown, it also includes a first stair section 11, located between the bottom platform 4 and the middle platform 5.

[0028] likeFigure 1 As shown, it also includes a second stair section 12, located between the middle platform 5 and the top platform 10.

[0029] Furthermore, such as Figure 3 , 4 As shown, both the first stair section 11 and the second stair section 12 include four support rods 13, and four pedals 14 are provided between the four support rods 13. Each pedal 14 has a first pivot 15 at both ends, and the pedal 14 is hinged to the support rod 13 through the first pivot 15. Rotating grooves and rotating holes are respectively provided on the first pivot 15 and the support rod 13 for mating connection. The bottom pedal 14 of the first stair section 11 is fixedly connected to the bottom platform 4 through four triangular connecting seats 18.

[0030] Furthermore, such as Figure 3 , 4 As shown, connecting plates 16 are provided on both sides of the first stair section 11 and the second stair section 12. Two support rods 13 at the top of the first stair section 11 and the second stair section 12 are fixedly connected to the connecting plates 16 on both sides, and two support rods 13 at the bottom of the first stair section 11 and the second stair section 12 are slidably connected to the connecting plates 16 on both sides. The connecting plates 16 have grooves for the sliding of the first rotating shaft 15. The connecting plates 16 of the first stair section 11 and the second stair section 12 are hinged to the bottom platform 4, the middle platform 5, and the top platform 10 respectively via three second rotating shafts 17. The middle platform 5 has an elongated hole for the second rotating shafts 17 to pass through, and these second rotating shafts 17 are connected to the top of the first stair section 11 and the bottom of the second stair section 12.

[0031] The steps 14 of the stair section are hinged to the four support rods 13 to form a variable and stable parallelogram linkage structure. The mounting plate 16 serves as a sliding pair of the parallelogram linkage structure, which can connect and fix the stair section between the platforms and keep the steps 14 parallel to each other during movement.

[0032] Furthermore, such as Figure 2 As shown, both the bottom platform 4 and the middle platform 5 are provided with extensions 19, which are used to extend to the bottom of the first step 11 and the second step 12 respectively, so as to support the treads at the bottom of the first step 11 and the second step 12.

[0033] In this embodiment, each frame and each stair section can be made of channel steel, square steel pipe and steel plate.

[0034] In this embodiment, during construction, the sliding of the middle platform 5 and the top platform 10 can be controlled by the guide rail 6 and the hydraulic lifting rod 9 respectively. The sliding control of the two is independent of each other and does not affect each other. In this way, the height of the middle platform 5 and the top platform 10 can be flexibly adjusted according to the construction conditions, which greatly improves the selectivity and flexibility of different orientation heights during construction, eliminates the height difference between the ladder cage entrance and the floor surface, and this embodiment is easy to set up, which is conducive to greatly improving construction efficiency.
