Description

Technical Field

[0001] This invention relates to an adaptive channel for aerial work platforms, belonging to the technical field of aerial work platforms. Background Technology

[0002] In high-altitude equipment maintenance, steel structure construction, and factory platform operations, there is often a fixed height difference between two work surfaces, requiring the construction of temporary access passages. Traditional fixed inclined ladders and simple scaffolding passages have significant drawbacks: 1. The passage has a fixed inclination angle, making it unsuitable for different height differences and lacking versatility; it requires re-fabrication and construction when changing height differences. 2. The steps of the inclined ladder tilt with the entire passage, causing a shift in the center of gravity when personnel walk, making them prone to slipping and falling. 3. The accompanying guardrails are directly fixed to the inclined beams, and when the passage tilts, the guardrails also tilt, rendering the protection ineffective and increasing the risk of falls from heights. 4. The overall structure is mostly welded as a single piece, which cannot be disassembled, making transportation and storage difficult. To address these shortcomings, this invention proposes an adaptive passage for high-altitude work platforms. Summary of the Invention

The fixed ladder 4111 has a panel slot 4114 in the middle of its top surface. The bottom of the panel slot 4114 has a first long bolt through hole 4115 on both the front and rear sides. The extension panel 4112 has a second long bolt through hole 4116 on both the front and rear sides of its top surface, which communicates with the first long bolt through hole 4115.

[0025] Each of the aforementioned steering mechanisms 43 includes a fixed rail 431, with a movable rail 432 laterally sliding at the lower end of the fixed rail 431. The left end of the movable rail 432 is threadedly connected to an adjusting screw 433 and a rotating seat 434. The bottom surface of the fixed rail 431 has a rail groove 4311 for the movable rail 432 to be fitted into. The middle of the left groove wall of the rail groove 4311 has a screw through-hole 4312 for the adjusting screw 433 to pass through.

The bottom surface of the movable rail 432 has multiple positioning slots 4322 spaced apart for the ladder hinge seat 42 to be fitted and locked.

[0026] Each of the guardrail post groups 51 includes a post body 511, and multiple anti-detachment seats 512 are spaced apart on the post body 511. A wire guide wheel 513 is fitted in the middle of the cavity of the anti-detachment seat 512.

[0027] The adaptive steel wire spacing seat 53 includes a steel wire hinge seat 531, on which a tension outer rod 532 is hinged. A tension groove 533 is provided in the middle of the tension outer rod 532, and a pull rod 534 and a pull rod spring 535 are fitted inside the tension groove 533.

[0028] Working principle: During high-altitude segmented assembly, the upper support rod group 31, lower support group 32, and vertical connecting rod group 33 on the same side must be assembled in advance. The upper support rod group 31 will have a steering mechanism 43 and a ladder hinge seat 42 fixed on its bottom surface, for a total of two. Then, it is hoisted to the high-altitude installation between the low-position installation base plate 1 and the high-position installation base plate 2. The first hinge collar 314 and the second hinge collar 315 are hinged to the corresponding support rod hinge seat 13 through pins. During the installation process, the main support rod 311 and the telescopic support rod 313 can be extended and retracted to adaptively adjust their length for easy hinge connection, adapting to the distance between the low-position installation base plate 1 and the high-position installation base plate 2. The vertical connecting rod group 33 can adaptively adjust its length to facilitate the adjustment of the distance between the upper support rod group 31 and the lower support group 32, adapting to the distance between the two support rod hinge seats 13 on the same side.

[0029] Then, assemble the triangular ladder 411, sleeve rod 412, adjusting rod 413, anti-detachment parts, and corresponding guardrail post group 51 in advance. There are multiple of them. Then, hoist them so that the sleeve rod 412 and the sleeve rod through hole 334 are aligned and threaded through. When threading the sleeve rod 412 and the sleeve rod through hole 334, the anti-detachment parts on both sides need to be removed first. After the sleeve rod 412 and the sleeve rod through hole 334 are threaded through, they are inserted. Then, the adjusting rod 413 and the corresponding ladder hinge seat 42 are hinged through the pin.

[0030] After installation, due to the different tilt angles between the parallelogram support assembly 3 and the lower mounting base plate 1 and the upper mounting base plate 2, the top surface of the triangular ladder 411 is tilted. The guardrail post assembly 51 tilts along with the top surface of the triangular ladder 411. It needs to be adjusted by the adjustment mechanism 43. During adjustment, the adjusting screw 433 is rotated. Through the threaded connection between the adjusting screw 433 and the screw through-hole 4312, the movable rail 432 slides laterally within the fixed rail 431. This causes the hinge of the ladder hinge seat 42 and the adjusting rod 413 to swing and level the right side of the triangular ladder 411. The guardrail post assembly 51 then becomes vertical. The upper right triangular ladder 411 needs to be adjusted by the fixed ladder 4111, the extension panel 4112, and multiple bolts 4113 to increase the area of ​​the top surface of the triangular ladder 411 and prevent a large gap between the upper right triangular ladder 411 and the upper mounting base plate 2.

[0031] Finally, the steel wire rope 52 and the steel wire self-adjusting distance seat 53 are installed and fixed between the guardrail post group 51, the first fixed guardrail 6, and the second fixed guardrail 7. The above segmented assembly is suitable for hoisting in areas with limited space for movement.

[0032] When the activity space allows the adaptive channel mechanism to be hoisted between the low-position mounting base plate 1 and the high-position mounting base plate 2, the adaptive channel mechanism needs to be assembled on the ground in advance. Only the steel wire rope 52 and the steel wire adaptive distance adjustment seat 53 can be assembled at high altitude later.
