Description

Technical Field

[0001] This invention belongs to the field of suspended platforms for building exterior wall construction, and more specifically, relates to safety protection devices and methods for suspended platforms used in exterior wall construction. Background Technology

[0002] With the continuous development of construction engineering, the number of high-rise and super high-rise buildings is increasing daily. As a crucial part of building construction, the safety and efficiency of exterior wall construction have received widespread attention. Among various exterior wall construction equipment, suspended platforms are a common tool widely used in the construction process. However, in the actual use of suspended platforms, safety has always been a key concern for construction workers and relevant management personnel.

[0003] Traditional suspended platform protective structures primarily use rubber protective sleeves, which are directly installed on the surface of the suspended platform. The main purpose of these sleeves is to prevent direct collisions between the suspended platform and the building's exterior wall during construction, thus protecting both the platform and the wall surface. However, this existing protective structure has many problems and limitations in practical use.

[0004] First, when suspended platforms are used for high-altitude operations, they may sway in the air due to factors such as wind, worker activity, and equipment operation. This swaying causes the protective structure to constantly rub and collide with the building's exterior walls, accelerating wear and tear. Over time, scratches and cracks will gradually appear on the surface of the protective cover, reducing its protective performance. This not only shortens the lifespan of the protective structure but may also affect the overall safety of the suspended platform to some extent. Summary of the Invention

[0005] In view of the above-mentioned defects or improvement needs of the existing technology, the present invention provides a safety protection device and method for suspended scaffolds used in exterior wall construction. When the surface of the exterior wall is smooth, the suction cup can be well adsorbed on the surface of the exterior wall. When the surface of the exterior wall is not smooth, the suction cup acts as a rubber buffer and is pressed against the wall surface. This can, to a certain extent, prevent the protective sleeve from directly impacting the surface of the exterior wall and causing wear and damage to the protective sleeve.

[0006] To achieve the above objectives, according to one aspect of the present invention, a safety protection device for a suspended scaffold used in exterior wall construction is provided, characterized in that it includes a protective sleeve for covering the outside of the suspended scaffold and a support device installed on the protective sleeve, wherein: The support device includes a connecting frame and a suction cup assembly. The suction cup assembly includes a rotating shaft, a suction cup connecting seat, a suction cup, a limiting frame, a first guide rod, and a first spring. The connecting frame is fixedly installed on the outside of the protective sleeve. The connecting frame has a receiving groove for accommodating the suction cup connecting seat and the suction cup. The first guide rod is fixedly installed on the connecting frame. The first spring passes through the first guide rod. One end of the first spring is fixedly connected to the connecting frame, and the other end is fixedly connected to the limiting frame. The limiting frame is installed on the first guide rod and can move along the length of the first guide rod. The suction cup connecting seat has a limiting groove. The end of the limiting frame near the suction cup connecting seat is the limiting end. The suction cup connecting seat is rotatably installed on the protective frame via the rotating shaft, so that the suction cup connecting seat can rotate to a first position and a second position. The suction cup is fixedly installed on the suction cup connecting seat, and: When the suction cup connecting seat is rotated to the first position, the limiting end of the limiting frame abuts against the suction cup connecting seat; When the suction cup connector is rotated to the second position, the suction cup connector and the suction cup are housed in the receiving groove. Under the action of the return force of the first spring, the limiting end of the limiting frame moves along the length direction of the first guide rod and enters the limiting groove, thereby limiting the suction cup connector in the limiting groove.

[0007] Preferably, the suction cup connecting seat includes a rotating block, a connecting block, a second guide rod, and a second spring. The rotating block is rotatably mounted on the connecting frame via the rotating shaft. One end of the second guide rod is fixedly connected to the rotating block. The connecting block is mounted on the second guide rod and can move along the length direction of the first guide rod. The second spring is threaded onto the second guide rod, with one end of the second spring abutting against the rotating block and the other end abutting against the connecting block. The suction cup is mounted on the connecting block.

[0008] Preferably, the connecting block is connected to the suction cup via a third guide rod. A third spring is mounted on the third guide rod. A movable ring is provided on the outer side of the suction cup. The movable ring is mounted on the third guide rod and can move along the length of the third guide rod. One end of the third spring abuts against the movable ring and the other end abuts against the connecting block, so as to move the movable ring along the length of the third guide rod, thereby squeezing the suction cup and making the suction cup adhere tightly to the outer wall. The connecting block is movably mounted on the third guide rod, or the third guide rod is a telescopic damping rod.

[0009] Preferably, rubber buffer blocks are installed on the opposite sides of the rotating block and the connecting block.

[0010] Preferably, the device further includes a limiting component, which comprises a storage frame, a sliding rod, a fourth guide rod, a fourth spring, and a limiting seat. The storage frame is fitted onto the protective sleeve and has a slide rail. The sliding rod is slidably mounted on the slide rail, and the storage frame has a second limiting structure to prevent the sliding rod from disengaging from the slide rail and falling off the storage frame. One end of the fourth guide rod is fixedly mounted on the storage frame, and the limiting seat is mounted on the other end of the fourth guide rod and can move along the length of the fourth guide rod. The fourth guide rod has a third limiting structure to prevent the limiting seat from falling off the fourth guide rod. The fourth spring is threaded onto the fourth guide rod, with one end abutting against the storage frame and the other end abutting against the limiting seat. The limiting seat has a slot so that the railing on the exterior wall can be engaged in the slot.

[0011] Preferably, the limiting seat includes an L-shaped plate, a fifth guide rod, a fifth spring, and a pressing plate. The L-shaped plate is fixedly connected to one end of the fifth guide rod. The fifth spring is a tension spring that is threaded onto the fifth guide rod. One end of the fifth spring is fixedly connected to the L-shaped plate, and the other end is fixedly connected to the pressing plate, so that the pressing plate cooperates with the L-shaped plate to clamp the railing.

[0012] Preferably, it further includes a sixth guide rod and a sixth spring. One end of the sixth guide rod is fixedly installed on the storage frame. The sliding rod is installed on the sixth guide rod and can move along the length of the sixth guide rod. The sixth spring is inserted through the sixth guide rod, with one end of the sixth spring abutting against the sliding rod and the other end abutting against the storage frame.

[0013] Preferably, a ball is detachably installed inside the suction cup, and the ball can roll inside the suction cup.

[0014] According to another aspect of the present invention, a suspended platform assembly for exterior wall construction is also provided, including the aforementioned suspended platform safety protection device, characterized in that it further includes a suspended platform, multiple steel ropes, a control cabinet, a cantilever frame, and a winch. The protective sleeve of the safety protection device for exterior wall construction is fixedly fitted on the outside of the suspended platform. One end of each steel rope is connected to the suspended platform and the other end is connected to the winch. Each steel rope passes through a pulley on the cantilever frame. The control cabinet is installed on the suspended platform or the safety protection device for exterior wall construction to control the winch via wireless control.

[0015] According to another aspect of the present invention, a method for protecting a suspended platform safety device used in exterior wall construction is also provided, characterized by comprising the following steps: 1) The winch is controlled by the control cabinet on the suspended platform. The winch moves the suspended platform and the safety protection device installed on the platform through the steel rope on the platform, so that the platform moves along the outer wall to the position where construction needs to be carried out. 2) After the suspended platform reaches the designated position, adjust the position of the suction cup connector of the suspended platform safety protection device so that the suction cup on the suction cup connector is attached to the exterior wall; 3) After the suction cup is attached to the exterior wall, adjust the position of the sliding rod and the limit seat on the sliding rod of the suspended platform safety protection device according to the position of the railing on the exterior wall, so that the limit seat on the sliding rod is aligned with the railing on the exterior wall, and then the limit seat on the sliding rod is inserted into the railing. 4) After the exterior wall construction is completed, first separate the limiting seat on the sliding rod from the railing, then rotate the suction cup connecting seat so that the suction cup and suction cup connecting seat are housed in the receiving groove of the connecting frame. Under the action of the first spring, the limiting frame also enters the limiting groove of the suction cup connecting seat, thereby limiting the suction cup connecting seat in the receiving groove. 5) The winch returns to the set position via a steel rope.

[0016] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects: 1) The present invention provides a safety protection device for a suspended platform for exterior wall construction. By setting a support device with a suction cup assembly, the suction cup connecting seat is rotatably installed on the connecting frame. When the exterior wall surface is smooth, the suction cup can tightly adhere to the platform, providing stable support and reducing contact and collision between the protective cover and the exterior wall. When the exterior wall surface is not smooth, the suction cup acts as a buffer, pressing against the wall surface as a buffer to prevent the protective cover from being directly impacted, greatly extending the service life of the protective cover, ensuring the safety and stability of the suspended platform during operation, and reducing the potential risks caused by damage to the protective cover.

[0017] 2) The present invention provides a safety protection device for a suspended platform for exterior wall construction. The suction cup assembly has a receiving groove in which the suction cup connecting seat and the suction cup can be stored when the suction cup is not needed. At this time, the limiting frame enters the limiting groove under the action of the first spring return force, which firmly limits the suction cup connecting seat and prevents it from loosening and shaking in the stored state, thus ensuring the integrity and safety of the suspended platform during movement.

[0018] 3) The present invention provides a safety protection device for suspended scaffolds used in exterior wall construction. The connecting frame is fixedly installed on the outside of the protective sleeve. The overall structure is easy to assemble and maintain. The components are connected and cooperated by components such as rotating shafts, guide rods, and springs. It has high reliability and is easy to adjust and adapt to different suspended scaffold models and exterior wall conditions. It has wide applicability and can effectively meet the current requirements of high-rise building exterior wall construction for the protective performance of suspended scaffolds.

[0020] 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.

[0021] Reference Figures 1-7 A safety protection device for a suspended platform used in exterior wall construction includes a protective sleeve 1 for covering the outside of the suspended platform and a support device 4 installed on the protective sleeve 1.

[0022] The support device 4 includes a connecting frame 401 and a suction cup assembly 400. The suction cup assembly 400 includes a rotating shaft 403, a suction cup connecting seat, a suction cup 406, a limiting frame 407, a first guide rod 408, and a first spring 409. The connecting frame 401 is fixedly installed on the outside of the protective sleeve 1. The suction cup connecting seat is rotatably installed on the protective frame via the rotating shaft 403 to adjust the position of the suction cup connecting seat. The suction cup 406 is fixedly installed on the suction cup connecting seat for adhering to the exterior wall. The connecting frame 401 is provided with a accommodating... The suction cup connector and the receiving groove 402 of the suction cup 406 are described. The first guide rod 408 is fixedly installed on the connecting frame 401. The first spring 409 is inserted through the first guide rod 408. One end of the first spring 409 is fixedly connected to the connecting frame 401, and the other end is fixedly connected to the limiting frame 407. The limiting frame 407 is installed on the first guide rod 408 and can move along the length direction of the first guide rod 408. The suction cup connector is provided with a limiting groove 410, and the end of the limiting frame 407 near the limiting frame 407 is the limiting end. The suction cup 406 is preferably detachably installed on the suction cup connector and can be replaced after the suction cup 406 is damaged. Multiple suction cup assemblies 400 can be provided.

[0023] The limiting frame 407 is preferably a U-shaped frame. The limiting frame 407 can be movably mounted on the first guide rod 408, or the limiting frame 407 can be fixedly mounted on the first guide rod 408, and the first guide rod 408 is a telescopic damping rod. Both of these methods can ensure that the limiting frame 407 can move along the length direction of the first guide rod 408.

[0024] When the suction cup connecting seat is rotated to the first position where the suction cup 406 can adhere to the exterior wall, one end of the limiting frame 407 is a limiting end and the limiting end abuts against the suction cup connecting seat.

[0025] When the suction cup connector is rotated to the second position, the suction cup connector and the suction cup 406 are housed in the receiving groove 402. Under the action of the return force of the first spring 409, the limiting end of the limiting frame 407 moves along the length direction of the first guide rod 408 and enters the limiting groove 410, thereby confining the suction cup connector within the limiting groove 410. The first spring 409 is a tension spring.

[0026] When using the protective device, the rubber protective sleeve 1 is directly installed on the surface of the suspended platform 2, so that the surface of the suspended platform 2 can directly hit the surface of the building's exterior wall.

[0027] When using the support device 4, the rotating block 404 is manually controlled to rotate on the surface of the rotating shaft 403, so that the rotating block 404 is perpendicular to the outer wall surface. When the outer wall surface is smooth, the suction cup 406 can be well attached to the outer wall surface. When the outer wall surface is not smooth, the suction cup 406 acts as a rubber buffer and is pressed against the wall surface. This can prevent the protective sleeve 1 from directly hitting the outer wall surface to a certain extent.

[0028] Furthermore, the suction cup connecting seat includes a rotating block 404, a connecting block 405, a second guide rod 411, and a second spring 412. The rotating block 404 is rotatably mounted on the connecting frame 401 via the rotating shaft 403. One end of the second guide rod 411 is fixedly connected to the rotating block 404. The connecting block 405 is mounted on the second guide rod 411 and can move along the length of the second guide rod 411. The second spring 412 is threaded onto the second guide rod 411, with one end abutting against the rotating block 404 and the other end abutting against the connecting block 405. The suction cup 406 is mounted on the connecting block 405. The second spring 412 is a compression spring.

[0029] The connecting block 405 can be movably mounted on the second guide rod 411, or the connecting block 405 can be fixedly mounted on the second guide rod 411, and the second guide rod 411 can be a telescopic damping rod. Both of these can ensure that the connecting block 405 can move along the length direction of the second guide rod 411.

[0030] The cooperation between the rotating block 404 and the connecting block 405, along with the connection method of the second guide rod 411 and the second spring 412, allows the suction cup 406 to have more flexible adjustment capabilities during suction operations. When the suction cup 406 contacts the exterior wall surface, and when the suspended platform 2 shakes, the second spring 412 is compressed and stretched. The elasticity of the second spring 412 can alleviate the impact force at the moment of suction, allowing the suction cup 406 to adhere more stably to the wall surface, enhancing the stability and reliability of suction.

[0031] The limiting bracket 407 is pulled towards the connecting frame 401 by the first spring 409, causing the limiting bracket 407 to pass through the top of the connecting frame 401. The limiting end of the limiting bracket 407 abuts against the surface of the rotating block 404 and can slide relative to the rotating block 404. When the support device 4 is not used, the rotating block 404 is rotated into the receiving groove 402, and the limiting bracket 407 is pushed towards the rotating block 404 by the first spring 409, causing the limiting end of the limiting bracket 407 to slide into the limiting groove 410. This effectively restricts the rotating block 404 inside the receiving groove 402.

[0032] Furthermore, the connecting block 405 is connected to the suction cup 406 via the third guide rod 414. A third spring 415 is mounted on the third guide rod 414. A movable ring 416 and a rubber ring 417 are provided on the outer side of the suction cup 406. The movable ring 416 is mounted on the third guide rod 414 and can move along the length of the third guide rod 414. One end of the third spring 415 abuts against the movable ring 416 and the other end abuts against the connecting block 405, so as to allow the movable ring 416 to move along the length of the third guide rod 414, thereby allowing the movable ring 416 to squeeze the suction cup 406, and thus allowing the suction cup 406 to better adhere to the outer wall. The connecting block 405 is movably mounted on the third guide rod 414, allowing it to move along the length of the third guide rod 414. Alternatively, the third guide rod 414 can be a telescopic damping rod, with the suction cup 406 and the connecting block 405 fixedly connected to its two ends, allowing the suction cup 406 to move along the length of the third guide rod 414. The third spring 415 is a compression spring. When the suction cup 406 abuts against the exterior wall, the exterior wall exerts a reaction force on the suction cup 406 and the third guide rod 414, causing the moving ring 416 and the connecting block 405 to cooperate in compressing the third spring 415. Simultaneously, the third spring 415 undergoes elastic deformation, compressing the moving ring 416, which in turn compresses the suction cup 406, allowing the suction cup 406 to adhere better to the exterior wall. The rubber ring 417 restricts the movement of the moving ring 416, preventing it from moving beyond the suction cup 406.

[0033] The movable ring 416 can be movably mounted on the third guide rod 414, or the movable ring 416 can be fixedly mounted on the third guide rod 414, and the third guide rod 414 can be a telescopic damping rod. Both of these can ensure that the third guide rod 414 can move along the length direction of the third guide rod 414.

[0034] Furthermore, rubber buffer blocks 413 are installed on the opposite sides of the rotating block 404 and the connecting block 405. The rubber buffer blocks 413 effectively reduce the impact force generated by the collision between the rotating block 404 and the connecting block 405, reducing mechanical wear and ensuring the stability and precision of the component connections. Simultaneously, the rubber material has good elastic recovery capabilities, ensuring a stable buffering effect over a long period, guaranteeing that the suction cup assembly maintains good operating condition even under frequent operation, further improving the performance stability of the entire safety protection device. When the suspended platform 2 shakes significantly, the rubber buffer blocks 413 are pressed against each other, thus providing a certain degree of cushioning.

[0035] Furthermore, it also includes a limiting component 5, which includes a storage frame 501, a sliding rod 503, a fourth guide rod 507, a fourth spring 509, and a limiting seat 500. The storage frame 501 is fitted onto the protective sleeve 1, and a slide rail is provided on the storage frame 501. The sliding rod 503 is slidably mounted on the slide rail, and a second limiting structure is provided on the storage frame 501 to prevent the sliding rod 503 from disengaging from the slide rail and falling off the storage frame 501. One end of the fourth guide rod 507 is fixedly mounted on the storage frame 501. On frame 501, the limiting seat 500 is mounted on the other end of the fourth guide rod 507 and can move along the length of the fourth guide rod 507. The fourth guide rod 507 is provided with a third limiting structure to prevent the limiting seat 500 from falling off. The fourth spring 509 is threaded onto the fourth guide rod 507, with one end abutting against the storage frame 501 and the other end abutting against the limiting seat 500. The limiting seat 500 is provided with a slot so that railings on the exterior wall can be engaged in the slot. The fourth spring 509 is a compression spring. Multiple limiting components can be provided.

[0036] The limiting seat 500 can be movably mounted on the fourth guide rod 507, or the limiting seat 500 can be fixedly mounted on the fourth guide rod 507, and the fourth guide rod 507 is a telescopic damping rod. Both of these can ensure that the limiting seat 500 can move along the length direction of the fourth guide rod 507.

[0037] The introduction of the limiting component 5 adds a crucial layer of protection to the suspended platform's safety system. The storage frame 501 is fitted onto the protective sleeve 1, and the sliding rod 503 can slide along the track, prevented from detaching by the second limiting structure, forming a stable frame structure. The cooperation of the fourth guide rod 507, the fourth spring 509, and the limiting seat 500 allows the limiting seat 500 to flexibly adjust its position and tightly fit the exterior wall railing. During operation of the suspended platform 2, the positions of the sliding rod 503 and the limiting seat 500 are adjusted promptly according to the distribution of railings at different locations on the exterior wall, locking the railings into the slots. This achieves an effective limiting connection between the suspended platform 2 and the building structure, preventing lateral displacement or increased swaying of the suspended platform 2 due to unforeseen circumstances, significantly improving the stability and safety of the suspended platform 2 during operation. Especially in situations involving strong winds or concentrated activity of construction workers causing significant swaying of the suspended platform 2, the limiting component 5 effectively constrains the displacement range of the suspended platform 2, reducing safety risks and ensuring the safety of construction personnel and the quality of construction work.

[0038] Furthermore, the limiting seat 500 includes an L-shaped plate 508, a fifth guide rod 510, a fifth spring 511, and a pressing plate 512. The L-shaped plate 508 is fixedly connected to one end of the fifth guide rod 510. The fifth spring 511 is a tension spring, which is mounted on the fifth guide rod 510. One end of the fifth spring 511 is fixedly connected to the L-shaped plate 508, and the other end is fixedly connected to the pressing plate 512, so that the pressing plate 512 cooperates with the L-shaped plate 508 to clamp the railing. The fifth spring 511 is a tension spring.

[0039] The extrusion plate 512 can be movably mounted on the fifth guide rod 510, or the extrusion plate 512 can be fixedly mounted on the fifth guide rod 510, which is a telescopic damping rod.

[0040] The L-shaped plate and the extrusion plate 512 work together to effectively clamp the guardrail. Under the tension of the fifth spring 511, it can firmly clamp external wall railings of different diameters, offering strong adaptability. Compared to a fixed limiting structure, this flexible and adjustable clamping method can more precisely conform to the shape of the railing and provide stronger lateral restraint, thus effectively confining the suspended basket 2 to one side of the external wall. A guide block 513 is also installed on the L-shaped plate 508, and the extrusion block is slidably mounted on the guide block 513.

[0041] Furthermore, a rubber strip 515 is fixedly connected to one side of the L-shaped plate 508, and a bolt 514 is threadedly connected to one side of the extrusion plate 512. The thread of the bolt 514 is used to abut against the rubber strip 515. When the extrusion plate 512 slides to the appropriate position, the bolt 514 is manually controlled to rotate, thereby causing the bolt 514 to press against one side of the rubber strip 515. This allows the extrusion plate 512 to be well restricted to one side of the L-shaped plate 508.

[0042] Furthermore, it also includes a sixth guide rod 504 and a sixth spring 505. One end of the sixth guide rod 504 is fixedly mounted on the storage frame 501. The sliding rod 503 is mounted on the other end of the sixth guide rod 504 and can move along the length of the sixth guide rod 504. The sixth spring 505 is threaded onto the sixth guide rod 504, with one end abutting against the sliding rod 503 and the other end abutting against the storage frame 501. The sixth guide rod 504 and the sixth spring 505 are preferably arranged within a connecting groove 502 provided on the storage frame 501. The sixth spring 505 is a compression spring.

[0043] The sliding rod 503 can be movably mounted on the sixth guide rod 504, or the sliding rod can be fixedly mounted on the sixth guide rod 504, which is a telescopic damping rod.

[0044] The sixth spring 505 abuts against the sliding rod 503 and the storage frame 501, providing elastic support for the sliding rod 503. This elastic connection method plays a certain role in buffering and shock absorption when the basket 2 sways, preventing the limiting component 5 from being damaged due to excessive impact from the rigid connection, and enhancing the durability and reliability of the limiting component 5.

[0045] Furthermore, a ball 418 is detachably mounted inside the suction cup 406, and the ball 418 can roll within the suction cup 406. When facing a slightly uneven wall surface or needing to cross minor obstacles, the ball 418 is driven to roll as the basket 2 moves, thus preventing the support device 4 from interfering with the movement of the basket 2 to some extent. The ball 418 can be detached when not in use.

[0046] Reference Figure 8 An external wall construction suspended platform assembly includes the aforementioned suspended platform safety protection device, a suspended platform 2, multiple steel cables 3, a control cabinet 6, a cantilever frame 7, and a winch. The protective sleeve 1 of the external wall construction suspended platform safety protection device is fixedly fitted onto the outside of the suspended platform 2. One end of each steel cable 3 is connected to the suspended platform 2, and the other end is connected to the winch. Each steel cable 3 passes through a pulley on the cantilever frame 7. The control cabinet 6 is mounted on the suspended platform 2 or the external wall construction suspended platform safety protection device to control the winch wirelessly. The winch can be mounted on the cantilever frame 7.

[0047] The protective sleeve 1 is tightly secured to the outside of the suspended platform 2, providing basic protection for the platform 2. Multiple steel cables 3 connect the suspended platform 2 to the winch, and work with the pulleys of the cantilever frame 7 to achieve stable lifting and movement of the suspended platform 2. The wireless control function of the control cabinet 6 enhances the ease and flexibility of operation, allowing construction personnel to remotely control the winch from inside the suspended platform 2, precisely controlling the position changes of the platform 2 and reducing the tedious steps and potential risks of manual adjustments. All components work together, fully utilizing the adsorption, buffering, and limiting functions of the safety protection devices. Compared to traditional suspended platform systems, overall safety is significantly improved, and construction efficiency is optimized due to the reasonable structural layout and automated control, meeting the high-performance and high-reliability requirements of modern high-rise building exterior wall construction.

[0048] According to another aspect of the present invention, a method for protecting a safety protection device for a suspended platform used in exterior wall construction is also provided, comprising the following steps: 1) The winch is controlled by the control cabinet 6 on the suspended platform 2. The winch drives the suspended platform 2 and the safety protection device installed on the suspended platform 2 to move along the outer wall to the position where construction needs to be carried out.

[0049] 2) After the suspended platform 2 reaches the designated position, adjust the position of the suction cup connecting seat of the suspended platform safety protection device so that the suction cup 406 on the suction cup connecting seat is attached to the exterior wall.

[0050] 3) After the suction cup 406 adheres to the exterior wall, adjust the position of the sliding rod 503 and the limiting seat 500 on the sliding rod 503 according to the position of the railing on the exterior wall, so that the limiting seat 500 on the sliding rod 503 is aligned with the railing on the exterior wall, and then the limiting seat 500 on the sliding rod 503 is inserted into the railing.

[0051] 4) After the exterior wall construction is completed, first separate the limiting seat 500 on the sliding rod 503 from the railing, then rotate the suction cup connecting seat so that the suction cup 406 and the suction cup connecting seat are housed in the receiving groove 402 of the connecting frame 401. The limiting frame 407 also enters the limiting groove 410 of the suction cup connecting seat under the action of the first spring 409, thereby limiting the suction cup connecting seat in the receiving groove 402.

[0052] 5) The winch drives the basket 2 back to the set position via the steel rope 3.

[0053] The detailed working process is as follows: When the worker is working, the servo motor drives the winding roller to rotate through the control cabinet 6, thereby causing the steel rope 3 to wrap around or move away from the winding roller. This effectively achieves the lifting and lowering of the suspended platform 2, making it easy to control the placement of the suspended platform 2 at a suitable position on the exterior wall. Multiple steel ropes 3 are connected, which to a certain extent ensures the stability of the suspended platform 2 in the air. The protective devices mostly use airbags filled with inert gas in the middle, which to a certain extent avoids adding weight to the suspended platform 2. The guardrail of the suspended platform 2 uses a grid structure to effectively reduce wind resistance. When using the protective structure, the rubber protective sleeve 1 is directly installed on the surface of the suspended platform 2, preventing the surface of the suspended platform 2 from directly impacting the surface of the building's exterior wall. Support devices are used. At step 4, the rotating block 404 is manually controlled to rotate on the surface of the rotating shaft 403. The first spring 409 pulls the limiting bracket 407 towards the connecting frame 401, causing the limiting bracket 407 to slide and fit onto the surface of the rotating block 404 after passing through the top of the connecting frame 401. This ensures that the rotating block 404 is vertical to the exterior wall surface. When the exterior wall surface is smooth, the suction cup 406 can adhere well to it. When the exterior wall surface is rough, the suction cup 406 acts as a rubber buffer, pressing against the wall surface. This helps to prevent the protective sleeve 1 from directly impacting the exterior wall surface. Furthermore, a ball 418 can be installed on the suction cup 406. The ball 418 is detachable. When the suspended platform 2 moves, the ball 418... Driven to roll, thus to some extent preventing the support device 4 from affecting the movement of the basket 2. When the support device 4 is not in use, the rotating block 404 is rotated into the receiving groove 402, and then the first spring 409 pulls the limiting frame 407 towards the connecting frame 401, so that one end of the limiting frame 407 slides into the limiting groove 410. This can effectively restrict the rotating block 404 inside the receiving groove 402. When the support device 4 is not in use, the third spring 415 squeezes the moving ring 416 away from the connecting block 405, thus squeezing the moving ring 416 into the middle of the two rubber rings 417. This can compress the volume of the suction cup 406 to some extent. When the basket 2 shakes, the second Spring 412 is compressed and stretched. When the amplitude is large, the rubber blocks are squeezed against each other, which can play a certain buffering role. When using the limiting component 5, the control sliding rod 503 slides out of the interior of the connecting groove 502 and the fourth spring 509 squeezes the L-shaped plate 508 towards the bottom of the inner wall of the sliding groove 506. The fifth spring 511 pulls the compression plate 512 towards the L-shaped plate 508. This can effectively hold the guardrail in place by the compression plate 512 and the L-shaped plate 508. When the compression plate 512 slides to the appropriate position, the bolt 514 is manually controlled to rotate, which causes the bolt 514 to squeeze against one side of the rubber strip 515. This can effectively limit the compression plate 512 to one side of the L-shaped plate 508.This design effectively confines the suspended platform 2 to one side of the exterior wall. When the platform 2 sways, the sixth spring 505 is compressed and stretched, providing a certain degree of cushioning.

[0054] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
