Description

Technical Field

[0001] This invention belongs to the technical field of building exterior wall construction equipment, and more specifically, relates to an auxiliary device and its construction method suitable for a suspended platform for building exterior wall construction. Background Technology

[0002] With the accelerated pace of modern urbanization and the booming development of the construction industry, high-rise and super high-rise buildings are springing up like mushrooms after rain. After the main structure is completed, these buildings often face heavy tasks of exterior decoration and maintenance, encompassing various operations such as exterior wall tiling, glass curtain wall installation, aluminum panel decoration, exterior wall paint spraying, and subsequent cleaning and maintenance. In traditional construction methods, steel pipe scaffolding was once the main auxiliary construction facility. However, faced with increasingly complex building shapes and extremely high building heights, erecting ground-mounted or cantilevered scaffolding is not only extremely costly and time-consuming, but also often subject to severe limitations such as limited site space and insufficient foundation bearing capacity, making it impossible for some projects to be constructed normally using external scaffolding. Against this backdrop, suspended platforms for high-altitude operations, as a more advanced, economical, and efficient construction machinery, have gradually replaced traditional scaffolding as the dominant method. Suspended platforms are erected on the roof of buildings via a suspension mechanism. A hoist drives the suspended platform up and down along the facade. They offer significant advantages such as flexible operation, convenient relocation, strong practicality, relatively high safety and reliability, substantial work efficiency, and small footprint, greatly solving the problem of difficult access to heights in complex construction environments. Therefore, suspended platforms have become an indispensable key piece of equipment in current exterior wall construction projects.

[0003] In current construction practices, electric suspended platforms are the most common type of equipment. Their basic working principle involves a suspension mechanism mounted on the building's roof extending a cantilever, lowering working and safety steel cables. A hoist and safety lock are installed on the suspended platform (i.e., the work basket). Construction workers operate buttons in the control box to drive the hoist up or down on the working steel cables, thereby transporting the suspended platform and the personnel and materials it carries to the designated working height. Given the high-risk nature of working at heights, ensuring safety is always the primary focus in the design, manufacture, and use of suspended platforms, and it is the first priority that must be upheld at any stage of construction. Existing standard suspended platform equipment is typically equipped with multiple safety protection mechanisms, including a swing-arm anti-tilt safety lock, a centrifugal speed limiter, an upper limit switch, and an emergency stop device. Under ideal or standard working conditions, these can basically meet the needs of vertical transportation and work platform support. Because of its strong adaptability to building outlines and the fact that it does not require a large amount of ground and facade space like scaffolding, suspended platform technology has greatly freed up construction productivity, enabling continuous and rapid progress in processes such as curtain wall installation and exterior wall decoration.

[0004] Although existing suspended platform technology is relatively mature and widely used, in complex engineering applications, its inherently flexible suspension structure still presents insurmountable technical defects and safety hazards, severely restricting the improvement of construction accuracy and the personal safety of workers. For example, existing suspended platforms are typical flexible connection systems, with the suspended platform suspended in the air solely by steel wire ropes. When the platform rises to a designated working position tens or even hundreds of meters high, the lack of rigid or semi-rigid connections to the building walls makes the entire system mechanically resemble a giant pendulum. In the event of sudden severe weather conditions such as high-altitude gusts or heavy rain, or during operations that generate reaction forces, such as drilling or installation, the platform is prone to violent shaking, rotation, or impacting the wall. This shaking can cause dizziness and panic among workers, severely impacting construction efficiency, and may even lead to collisions with expensive curtain wall glass or stone, damaging exterior wall decorations, or even causing serious safety accidents such as platform overturning and personnel falls.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0024] Example 1, please refer to Figures 1 to 4 This invention provides an auxiliary device for a suspended platform used in building exterior wall construction, comprising: a fixing box 2, a support assembly 3, and an adsorption assembly 4; The fixed box 2 is fixedly mounted on the side of the suspended basket 1 facing the building exterior wall by the support component 3; the fixed box 2 is a hollow structure, and a first buffer pad 201 is fixedly mounted on the side of the suspended basket facing the building exterior wall; The adsorption assembly 4 includes at least five suction cups 401 and a vacuum machine 402; the suction cups 401 are inserted through the side plate of the fixed box 2 facing the exterior wall of the building, and their openings protrude to the outside of the first buffer pad 201; the vacuum machine 402 is fixedly mounted on the hanging basket 1. The multiple suction cups 401 are interconnected through pipes inside the fixed box 2, and these pipes are connected to the air extraction port of the vacuum machine 402 via air extraction hoses.

[0025] Understandably, during use, the fixed box 2 is securely installed on the side of the suspended basket 1 facing the building's exterior wall via the support assembly 3. Its side panel facing the wall is equipped with a first buffer pad 201, which effectively absorbs impact and prevents rigid collisions when in contact with the wall, protecting the building's finish and equipment structure. The adsorption assembly 4 includes at least five suction cups 401 and a vacuum machine 402. Each suction cup 401 passes through the side panel of the fixed box 2 and protrudes beyond the first buffer pad 201, ensuring full contact with the wall surface. Multiple suction cups 401 are interconnected through internal pipes in the fixed box 2 and connected to the vacuum machine 402 on the suspended basket 1 via a vacuum hose. When the suspended basket 1 is raised to the designated construction height, the vacuum machine 402 is activated to simultaneously create a vacuum, causing all suction cups 401 to form a uniform and reliable negative pressure adsorption force on the building's exterior wall, thereby firmly anchoring the suspended basket 1 to the wall surface.

[0026] In an optional embodiment, multiple suction cups 401 are arranged in a quincunx pattern on one side of the fixed box 2, thereby forming a centrally symmetrical and multi-directionally supported adsorption array in space. This not only effectively expands the contact coverage with the building's exterior wall, but also ensures that at least three suction cups 401 remain stably attached under different wall flatness conditions, thus improving the overall adsorption reliability. At the same time, this arrangement helps to evenly distribute the negative pressure load, avoiding local stress concentration that could lead to sealing failure or suction cup 401 detachment. This significantly enhances the anti-overturning and anti-wind disturbance capabilities of the suspended platform 1 in fixed-point operation, further ensuring the safety and stability of high-altitude construction.

[0027] In an optional embodiment, the buffer plate 201 is made of elastic rubber material. It is understood that, through the above design, when the suspended platform 1 approaches or contacts the building's exterior wall, the first buffer pad 201 can effectively buffer the instantaneous impact caused by operational errors or wind disturbances, preventing rigid collisions between the suspended platform 1 and the wall, thereby protecting the building's exterior facade from damage and reducing vibration impact on the suspended platform 1's main structure. Furthermore, the elastic rubber material has good sealing adaptability, can conform to walls with varying flatness, providing a stable pre-pressure contact environment for the suction cup 401, and improving its vacuum adsorption sealing effect and reliability.

[0028] Furthermore, the support assembly 3 includes: a positioning plate 301, a damping adjustment arm 302, and a support rod 303; The positioning plate 301 is fixedly installed on the side of the suspended basket 1 facing the exterior wall of the building; There are four damping adjustment arms 302, and each of the damping adjustment arms 302 is hinged at one corner of the positioning plate 301 and the fixed box 2 respectively. The two ends of the support rod 303 are respectively hinged to the positioning plate 301 and the middle of the fixed box 2.

[0029] Understandably, during use, the positioning plate 301 is fixedly installed on the side of the suspended platform 1 facing the building's exterior wall, serving as the overall support base; the four damping adjustment arms 302 are respectively hinged to the corresponding corners of the positioning plate 301 and the fixed box 2, providing not only multi-point constraints but also absorbing external disturbance energy through the built-in damping mechanism, effectively suppressing the swaying of the suspended platform 1 during lifting or fixed-point operation; the support rod 303 set in the middle connects the positioning plate 301 and the center of the fixed box 2, forming a stable triangular support system, enhancing the overall rigidity and preventing the fixed box 2 from twisting or shifting.

[0030] In an optional embodiment, the damping adjustment arm 302 includes: two connecting rods 302a and a damper 302b; One end of each of the two connecting rods 302a is respectively hinged to one side of the positioning plate 301 and the fixed box 2; The damper 302b is used to connect the other end of the two connecting rods 302a.

[0031] Understandably, through the above design, when the suspended platform 1 approaches an uneven or sloping building exterior wall, the fixed box 2 can freely adjust its tilt angle according to the wall contour, while the damper 302b provides controllable damping force during the movement, effectively suppressing vibration and impact caused by wind load or operational disturbance, and achieving stepless locking and stable support at any tilt position.

[0032] It should be noted that in this embodiment, the damper 302b is an FYN-LA3 type rotary damper. In other embodiments, other types of dampers can also be used, as long as the fixed box 2 can be freely adjusted to follow the contour of the wall. No specific limitation is made here, but these solutions are all within the protection scope of this invention.

[0033] Furthermore, the auxiliary device also includes a dust removal assembly 5, which includes a nozzle 501 and an air compressor 502; The nozzle 501 is inserted through the fixed box 2 on the side facing the building's exterior wall; The plurality of nozzles 501 correspond to one suction cup 401 and are arranged around the suction cup 401; the nozzles 501 spray air in the front end region of the opening of the suction cup 401; The plurality of nozzles 501 are interconnected by a pipe provided in the fixed box 2, and the pipe is connected to the air compressor 502 through an air delivery hose; The air compressor 502 is fixedly mounted on the suspended basket 1.

[0034] Understandably, through the above design, before the suspended platform 1 reaches the working position, the air compressor 502 fixed on the suspended platform 1 is started. Compressed air is delivered to each nozzle 501 through the air delivery hose and the pipeline inside the fixed box 2, which instantly blows the wall adsorption area to remove impurities such as dust, debris or water film, thereby ensuring that the contact surface between the suction cup 401 and the wall is clean and dry, significantly enhancing the vacuum sealing effect, avoiding adsorption failure due to contaminants, thereby improving the stability and safety of the fixed-point fixation of the suspended platform 1, and is especially suitable for complex construction environments such as windy and sandy, high humidity or old wall renovation.

[0035] Furthermore, the auxiliary device also includes: rollers 6 and limiting components 7; the limiting components 7 are fixedly mounted on the upper end of the fixed box 2 and are used to adjust the contact state between the rollers 6 and the building exterior wall; the rollers 6 are fixedly mounted on the side of the limiting components 7 facing the building exterior wall. It can be understood that, through the above design, during the ascent or descent of the suspended platform 1, the rollers 6 preferentially contact the wall surface and achieve auxiliary rolling, effectively reducing the frictional resistance between the suspended platform 1 and the wall, improving the stability of lifting and lowering, and preventing scratches to the exterior facade; when the suspended platform 1 reaches the designated working height and needs to be fixed by suction, the limiting components 7 drive the rollers 6 to retract, so that the first buffer pad 201 and the suction cup 401 fully contact the wall surface, ensuring the sealing and reliability of the vacuum suction.

[0036] In an optional embodiment, the upper end of the fixed box 2 is provided with at least two sets of adjustment units consisting of the rollers 6 and the limiting components 7, thereby forming multi-point rolling support when the suspended basket 1 moves vertically along the building's exterior wall, effectively dispersing the contact load and avoiding swaying or jamming caused by single-point force; at the same time, each roller 6 independently controls its extension and retraction state through the corresponding limiting components 7, extending synchronously during the lifting and lowering phase to achieve smooth rolling, and retracting synchronously during the adsorption and fixing phase, ensuring that the first buffer pad 201 and suction cup 401 are fully attached to the wall surface, and the sealing effect is not affected by the interference of the rollers 6.

[0037] In an optional embodiment, the limiting component 7 includes: a support rod 701, a fixing sleeve 702, a spring pull rod 703, a connecting plate 704, and a handle 705; The support rod 701 is fixedly mounted on the upper end of the fixed box 2; The fixing sleeve 702 is fixedly disposed on one side of the support rod 701 along the width direction of the fixing box 2; the fixing sleeve 702 is a hollow structure and has openings at both ends; The spring rod 703 includes: a rod 703a, a spring 703b, a first limiting plate 703c, and a second limiting plate 703d; The pull rod 703a is inserted into the fixed sleeve 702, and one end of the pull rod 703a passes through the opening of the fixed sleeve 702 near the basket 1 and is fixedly connected to the first limiting plate 703c, and the other end is fixedly connected to the second limiting plate 703d provided in the fixed sleeve 702. The spring 703b is sleeved on the outside of the pull rod 703a inside the fixed sleeve 702; The second limiting plate 703d slides in conjunction with the inner wall of the fixed sleeve 702; The radial dimensions of the first limiting plate 703c and the second limiting plate 703d are both larger than the inner diameter of the openings at both ends of the fixed sleeve 702. One end of the connecting plate 704 is fixedly connected to the roller 6, and the other end passes through the opening of the fixed sleeve 702 and is fixedly connected to the second limiting plate 703d; One end of the handle 705 is provided with a connecting hole, and through the connecting hole, it is sleeved onto a portion of the structure of the pull rod 703a between the first limiting plate 703c and the fixed sleeve 702.

[0038] Understandably, with the above design, during operation, by pulling the handle 705 to drive the lever 703a to overcome the resistance of the spring 703b, the roller 6 can be extended or retracted. Then, by rotating the handle 705 to make it abut against the side of the fixed box 2 facing the basket 1, the position can be mechanically locked.

[0039] Example 2, please refer to Figure 5 and Figure 6 Based on Embodiment 1, the auxiliary device in this embodiment further includes a suspension assembly 8 and a support assembly 3. The suspension assembly 8 includes: two suspension frames 801, a central connecting rod 802, a support plate 804, and multiple hanging rings 803; The two ends of the central connecting rod 802 are respectively fixedly connected to the middle of the upper crossbeams of the two suspension frames 801; The two ends of the support plate 804 are respectively fixedly connected to the middle of the lower crossbeams of the two suspension frames 801, for detachable connection with the hanging basket 1; The support assembly 3 includes a positioning plate 301, which is connected to the side of the two suspension frames 801 facing the building exterior wall; the fixing box 2 is mounted on the positioning plate 301 via the support assembly 3. The five lifting rings 803 are respectively located at the middle of the upper surface of the central connecting rod 802 and at both ends of the upper surface of the crossbeam of each suspension frame 801.

[0040] Understandably, during use, the two suspension frames 801 are arranged in a mirror-symmetric manner with respect to the axis of the central connecting rod 802, resulting in balanced structural stress. The five lifting rings 803 are respectively located at the middle of the upper surface of the central connecting rod 802 and at both ends of the upper crossbeam of each suspension frame 801, facilitating connection with the lifting wire rope or multi-point suspension system of the suspended platform 1, achieving uniform load distribution and improving the overall anti-overturning capacity. The support plate 804 connects the middle of the lower crossbeam of the two suspension frames 801 and is detachably connected to the suspended platform 1 by bolts, ensuring structural rigidity and facilitating on-site installation and maintenance. At the same time, the positioning plate 301 is fixed at both ends to the rear column of the suspension frame 801, making the support component 3 and the suspension component 8 form an integrated frame system, significantly enhancing the overall rigidity and spatial stability of the device, ensuring reliable collaborative operation of each functional module during lifting and adsorption fixation, and effectively improving the safety and construction efficiency of high-altitude operations.

[0041] In an optional embodiment, the suspension assembly 8 further includes a second buffer pad 805, which is fixedly disposed on the upper surface of the support plate 804, thereby effectively improving the overall vibration reduction performance and structural protection capability of the device.

[0042] In an optional embodiment, the suspension assembly 8 further includes: three traction ropes 806 and a rope catcher 807; One traction rope 806 is threaded through the lifting ring 803 on the middle connecting rod 802; the other two traction ropes 806 are respectively threaded through the lifting rings 803 at the same end of the crossbeams of the two suspension frames 801. The rope catcher 807 is located above the shackle 803 on the central connecting rod 802 and is used to simultaneously gather the ends of the three traction ropes 806.

[0043] Understandably, during use, the three traction ropes 806 added to the suspension assembly 8 and the rope binder 807 form a three-rope five-ring suspension structure. This structure can automatically balance the force on each rope during the lifting process of the suspended platform 1, effectively suppressing the left and right tilting caused by load eccentricity, wind load disturbance or asynchronous hoisting, and ensuring that the suspended platform always remains horizontal. At the same time, the multi-point suspension enhances the overall torsional stiffness and safety redundancy, greatly improving the stability, reliability and safety of high-altitude operations.

[0044] In an optional embodiment, the inner wall of the lifting ring 803 is provided with a smooth layer 803a, and a plurality of balls 803b are uniformly embedded in the circumferential direction on the surface of the smooth layer 803a, in order to reduce the frictional resistance between the traction rope 806 and the lifting ring 803 during operation. It can be understood that through the above design, not only is it ensured that the three traction ropes 806 pass smoothly through the lifting ring 803 during the lifting process, improving the dynamic response and tension balance of the three-rope five-ring suspension system, but it can also extend the service life of the traction ropes 806 and the lifting ring 803, avoiding safety hazards caused by local overheating or breakage, thereby ensuring the stable, safe and efficient operation of the suspended basket 1.

[0045] Example 3, please refer to Figure 7 This invention provides a construction method for an auxiliary device suitable for a suspended platform in building exterior wall construction, comprising the following steps: S1: Securely install the fixing box 2 on the side of the suspended basket 1 facing the building exterior wall using the adaptive component 3; at the same time, confirm that the vacuum machine 402 in the adsorption component 4 is fixed on the suspended basket 1, and complete the sealed connection between the suction cup 401 and the internal pipe and exhaust hose of the fixing box 2. S2: Start the lifting system of the suspended platform 1 to raise it smoothly along the building facade to the predetermined construction height; during this process, the first buffer pad 201 moves closer to the wall synchronously with the fixed box 2; S3: When the basket 1 reaches the target position, its posture is slightly adjusted so that the first buffer pad 201 on the fixed box 2 gently abuts against the building exterior wall. The elasticity of the first buffer pad 201 is used to adapt to the local unevenness of the wall surface, ensuring that the opening ends of each suction cup 401 can effectively fit the wall surface. S4: The operator starts the vacuum machine 402 and draws air from the pipe inside the fixed box 2 through the exhaust hose, so that five or more suction cups 401 simultaneously form negative pressure, and perform uniform and reliable vacuum adsorption on the external wall, thereby firmly fixing the hanging basket 1 to the designated working position. S5: After the suspended platform 1 is stably anchored, the exterior wall construction work will be carried out; S6: After the current work surface is completed, turn off the vacuum machine 402 and release the negative pressure in the suction cup 401 to release the adsorption; operate the basket 1 to move horizontally or lift it to the next construction area, and repeat steps S2 to S5 to complete all work tasks.
