Description

Technical Field

[0001] This utility model relates to an operating platform, specifically an adjustable and adaptive mobile operating platform for the repair of ancient buildings, belonging to the field of building construction equipment technology. Background Technology

[0002] The restoration and construction of ancient buildings, especially the work on the exterior eaves, faces two major challenges: First, the complexity of the working environment, such as narrow courtyards, uneven ground (slopes, steps), and obstacles such as thresholds, makes it difficult for large equipment to enter and move flexibly; second, the special nature of the restoration process requires the work platform to be able to flexibly adapt to different depths of the exterior eaves, and to absolutely ensure the stability of the structure and the safety of personnel during the construction process, while adhering to the "principle of minimal intervention" in cultural relic protection.

[0003] Currently, traditional scaffolding is cumbersome to erect and dismantle and has poor mobility. Standard aerial work vehicles or work platforms are often bulky, have high ground pressure, and are difficult to adapt to ancient building floors. In addition, their support and working range adjustment capabilities are limited, making it impossible to efficiently cross obstacles or adapt to complex facades while ensuring stability. To address these issues, we provide an adjustable and adaptive mobile operating platform for the restoration of ancient buildings. Utility Model Content

[0027] This utility model provides an adjustable and adaptive mobile operating platform for the repair of ancient buildings.

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes a central lifting pole 1 and a fixed frame 2. The inner wall of the fixed frame 2 is fixedly connected to the central lifting pole 1. A cantilever mechanism 3 is provided on the outside of the central lifting pole 1. The cantilever mechanism 3 includes an operating platform 301. The bottom surface of the operating platform 301 is fixedly connected to the telescopic end of the central lifting pole 1. A guardrail 302 is fixedly connected to the top surface of the operating platform 301. A limit groove 303 is provided on the top surface of the operating platform 301. A movable support mechanism 4 is provided on the outside of the central lifting pole 1. The movable support mechanism 4 includes an auxiliary telescopic rod 401. The telescopic end of the auxiliary telescopic rod 401 is fixedly connected to the operating platform 301. The outer surface of the auxiliary telescopic rod 401 is fixedly connected to the fixed frame 2. A locking hole 402 is provided on the outer surface of the auxiliary telescopic rod 401. The lifting of the central lifting pole 1 can drive the overall lifting of the operating platform 301. The auxiliary telescopic rod 401 is locked by a pin that cooperates with the locking hole 402 to improve the stability of the operating platform 301.

[0029] The inner wall of the limiting slide groove 303 is slidably connected to the driven slide rod 304, and the outer surface of the driven slide rod 304 is fixedly connected to the second operating platform 305. The second operating platform 305 can slide along the direction of the limiting slide groove 303 with the driven slide rod 304. This sliding structure realizes the extension and retraction of the second operating platform 305 relative to the first operating platform 301.

[0030] The top surface of the second operating platform 305 is fixedly connected to the second guardrail 306. The outer surface of the second guardrail 306 is slidably connected to the first guardrail 302. When the second guardrail 306 moves with the second operating platform 305, it maintains a slidable connection with the first guardrail 302. The first guardrail 302 and the second guardrail 306 together form an expandable continuous safety protection structure.

[0031] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 A limiting ring 307 is fixedly connected to the outer surface of the auxiliary telescopic rod 401. An inclined adjustment rod 308 is rotatably connected to the inner wall of the limiting ring 307. The telescopic end of the inclined adjustment rod 308 is rotatably connected to the driven slide rod 304. The telescopic movement of the inclined adjustment rod 308 can push or pull the driven slide rod 304 to slide in the limiting slide groove 303. The limiting ring 307 provides a stable fulcrum for the rotation of the inclined adjustment rod 308.

[0032] Telescopic adjustment rods 403 are fixedly connected to the fixed ends of the central lifting pole 1 and the auxiliary telescopic pole 401 and the bottom surface of the fixed frame 2. Each telescopic adjustment rod 403 has a drive wheel 404 fixedly connected to its telescopic end. An angle sensor is installed inside the telescopic adjustment rod 403. The telescopic adjustment rod 403 is used to adjust the height of the drive wheel 404 relative to the platform body. This structure allows the drive wheel 404 to adapt to uneven ground to maintain platform stability.

[0033] An inclined telescopic rod 405 is hinged to the outer surface of the fixed frame 2. A support plate 406 is hinged to the telescopic end of the inclined telescopic rod 405. The inclined telescopic rod 405 can extend and retract to change the contact state between the support plate 406 and the ground. The support plate 406 is used to increase the contact area with the ground to improve the overall support stability.

[0034] The top surface of the operating platform 301 is fixedly connected to the hoisting equipment 5, and the outer surface of the operating platform 301 is provided with a ladder limiting groove 6. The hoisting equipment 5 is used to lift construction materials or tools onto the operating platform 301, and the ladder limiting groove 6 is used to fix the ladder so that construction personnel can safely enter and exit the operating platform.

[0035] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0036] In use, this utility model consists of three core components working collaboratively: a terminal intelligent control system, a cantilever mechanism 3, and a mobile support mechanism 4. The central lifting pole 1 and the fixed frame 2 form the main structural components. The intelligent control system uses a PID algorithm to coordinate the movements of the cantilever mechanism 3 and the mobile support mechanism 4. When the platform moves, tilt sensors are installed between the telescopic adjustment rods 403 and the drive wheels 404. All telescopic adjustment rods 403 independently fine-tune based on the feedback from the tilt sensors to adapt to ground undulations, ensuring that the fixed frame 2 and its operating platform 301 remain level. When encountering obstacles such as steps, the system activates a preset "obstacle-crossing mode." First, the two rear telescopic adjustment rods 403 extend, ensuring the drive wheels 404 are firmly grounded and bear the main weight. Then, the two middle telescopic adjustment rods 403 retract, raising the middle drive wheels 404 to avoid the obstacle. At this time, the system drives the two front drive wheels 404 to rotate, propelling the platform forward with the front as the fulcrum. The platform rotates to smoothly cross the obstacle in the middle. After crossing the obstacle, the middle telescopic adjustment rod 403 immediately extends to re-ground the drive wheel 404 and bear the weight. Then the rear telescopic adjustment rod 403 retracts, completing a non-destructive obstacle crossing. This three-wheeled center of gravity transfer logic is the key to the platform's mobility. After arriving at the work point, in order to obtain ultimate stability, the tilt telescopic rod 405, which is hinged to the fixed frame 2, unfolds, so that the support plate 406 at its end is reliably grounded, forming a stable multi-point support system together with the drive wheel 404. At the same time, the cantilever operation begins. The second operating platform 305 slides in the limiting groove 303 of the first operating platform 301 through the driven slide rod 304 to adjust the working range, while the tilt adjustment rod 308 extends and retracts synchronously to provide rigid support for the cantilever part. Throughout the process, the safety interlock function of the intelligent control system ensures that heavy load cantilever operations are only allowed after the support system is fully unfolded and grounded, thus comprehensively ensuring construction safety and efficiency in complex ancient building environments.
