Description

Technical Field

[0001] This invention belongs to the field of work platform technology, specifically a foldable edge-operating platform for high-rise building curtain wall construction. Background Technology

[0002] Foldable edge work platforms are mainly used for curtain wall construction of high-rise buildings. They are erected at the edge of the building structure and, when unfolded, provide workers with a stable edge working space to meet the construction needs of curtain wall keel installation, glass panel hoisting and positioning, and caulking and sealing. After completion, they can be folded inward to avoid protruding outward and affecting vertical transportation and subsequent construction. They also have edge work load-bearing and safety protection functions. Compared with traditional cantilever platforms, they are easier to assemble and disassemble and occupy less space, effectively improving the safety of high-altitude curtain wall construction and site utilization.

[0003] A Chinese patent with publication number CN106437121A discloses an industrialized prefabricated construction platform for external work on buildings, designed to withstand falling objects. The platform includes a frame detachably connected to the building's exterior wall, horizontally arranged operating platforms mounted on the frame, and vertically arranged external protective barriers. The protective barriers, operating platforms, and the corresponding building exterior wall together form the work space for construction workers. The two sides of the protective barriers are hinged to protective doors. Multiple operating platforms are arranged horizontally along the building's exterior wall to form an operating passage. When it is necessary to isolate any operating platform, the protective doors on one or both sides of the corresponding platform can be closed. This invention, considering both practical engineering conditions and characteristics, effectively solves the problem of construction workers lacking operating platforms for external wall work by installing and fixing multiple operating platforms to the building's exterior wall to form a worker operating passage. Furthermore, the invention has a simple and reliable structure, is easy and standardized to install, can be reused, and is more aesthetically pleasing than traditional cantilever scaffolding.

[0004] Existing folding edge-operated platforms for high-rise building curtain wall construction are difficult to adjust the effective working support area flexibly according to the on-site construction conditions when supporting construction personnel to carry out curtain wall construction work. The overall flexibility of use is poor, and it cannot adapt to diverse application scenarios such as changes in the number of personnel, temporary material stacking, and corner curtain wall construction. If the platform's preset working area is too large, the overall size of the platform will increase accordingly, and it will still occupy a lot of space when folded up, which can easily interfere with the hoisting of curtain wall panels and other construction procedures on the facade. On the other hand, if the platform area is too small, it is difficult to meet the operational needs under complex working conditions, and its versatility is obviously limited.

[0005] Therefore, the present invention provides a foldable edge-operated platform for the construction of curtain walls of high-rise buildings. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies and solve the problem of difficulty in flexibly adjusting the effective working support area according to the on-site construction conditions, this invention proposes a foldable edge-operating platform for high-rise building curtain wall construction.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A folding edge-operating platform for high-rise building curtain wall construction, comprising a bearing plate, a positioning block fixedly disposed on the side of the bearing plate, a concave frame fixedly disposed on the bearing plate, a support block passing through the concave frame, an adjustment mechanism for adjusting the position of the support block disposed within the concave frame, a storage box fixedly disposed on the support block, a support plate disposed on the top of the storage box, and an adjustment component for adjusting the vertical position of the support plate disposed within the storage box. The system includes a storage slot with a connecting plate passing through it. A side rail is fixedly mounted on the connecting plate, and a horizontal rail is fixedly mounted on the support plate. A movable box is fixedly mounted at the bottom of the support plate and is connected to the storage slot. A support frame is fixedly mounted inside the movable box, and a dual-shaft motor is fixedly mounted inside the support frame. An adjusting screw is rotatably mounted inside the movable box, and the end of the adjusting screw is fixedly connected to the output end of the dual-shaft motor. An adjusting block is fixedly connected to the bottom of the connecting plate, and the outer surface of the adjusting screw is threadedly connected to the inside of the adjusting block.

[0008] By adopting the above solution, when using the foldable edge protection platform for high-rise curtain wall construction to provide working space for workers, installation points corresponding to the positioning blocks are pre-set on the floor. Bolts are used in conjunction with the positioning blocks to position the support plate, thereby positioning and installing the foldable edge protection platform. When not in use, the platform folds up, and side railings and horizontal railings provide protection for the unfinished side of the floor. There is no need to erect a separate steel pipe edge protection system, eliminating the risks of high-altitude operations caused by the erection and dismantling of protective measures, as well as the gap period without edge protection. Furthermore, the railings are linked components of the platform itself, making them difficult for workers to dismantle independently, resulting in higher protection reliability. This also reduces the input of reusable materials such as steel pipes and fasteners, simplifies on-site construction procedures, and achieves integrated reuse of the curtain wall work platform and floor edge protection. The controller is electrically connected to the electronic equipment on the foldable edge protection platform, allowing control of the electronic equipment's operation. During curtain wall construction, the control mechanism can adjust the position of the support blocks, which can be carried away through a storage box. The moving support plate, horizontal railing, and side railing move synchronously, thus moving them out of the building and adjusting their front and rear positions to the predetermined positions. The support plate then provides a working space for workers, facilitating curtain wall construction on high-rise buildings. Adjustable components allow for vertical adjustment of the support plate, enabling flexible adjustment of the working position and improving flexibility. When expanding the working area, controlling the dual-shaft motor drives the adjusting screws to rotate. The two sets of adjusting screws have opposite threads, thus adjusting the position of the adjusting block as the screws rotate. The movement of the adjusting block also moves the connecting plate. After the connecting plate moves from the storage slot to the outside, its position is fixed, expanding the working platform area. When not needed, the connecting plate can be folded and stored, reducing its footprint and expanding the effective working area of ​​the platform. This meets the needs of multiple workers simultaneously and temporary material storage. The connecting plate can be folded and stored when not in use, reducing the overall platform space and facilitating platform storage and placement, minimizing interference with the external facade construction space. This allows for flexible adjustment of the working area, balancing practicality and space efficiency.

[0009] Preferably, a guide cylinder is provided inside the support block, a guide rod is inserted inside the guide cylinder, and the other end of the guide rod is fixedly connected to the inner wall of the concave frame.

[0010] By adopting the above scheme, when adjusting the position of the support block, the support block is guided by the cooperation of the guide cylinder and the guide rod, so that the support block moves smoothly.

[0011] Preferably, the adjusting mechanism includes a threaded screw, a power motor, a reducer, and pulleys. The threaded screw is rotatably disposed inside the concave frame, and the outer surface of the threaded screw is threadedly connected to the inside of the support block. The reducer is fixed to the top of the concave frame, and the power motor is fixed to the reducer. The output end of the power motor is fixedly connected to the input end of the reducer. Both the threaded screw and the output end of the reducer are fixedly connected to pulleys, and the two sets of pulleys are connected by belt drive.

[0012] By adopting the above scheme, controlling the power motor to work will drive the reducer to move. When the reducer moves, it will drive the threaded screw to rotate through the cooperation of two sets of pulleys. When the threaded screw rotates, it will adjust the position of the support block, thereby adjusting the front and rear position of the storage box.

[0013] Preferably, a protective cover is fixedly provided on the side of the concave frame, and the protective cover is located on one side of the pulley.

[0014] By adopting the above solution, a protective cover is used to protect the pulley, effectively preventing external factors from affecting the pulley transmission.

[0015] Preferably, the concave frame is symmetrically provided with locking blocks, the support block is fixedly provided with a locking groove corresponding to the locking block, and the locking block engages with the corresponding locking groove. The top of the locking block is provided with an installation groove, and the installation groove is provided with an array of support wheels.

[0016] By adopting the above scheme, when the position of the support block is adjusted, the slot will move. Through the cooperation of the slot and the support block, the support block will be further guided, so that the support block moves smoothly. The top of the support wheel supports the top of the inner wall of the slot, and the support wheel can easily assist the slot in moving, so that the support block moves smoothly.

[0017] Preferably, the adjustment assembly includes a cross lifting linkage and an electric push rod. The cross lifting linkage is located inside the storage box and is connected to the bottom of the support plate. The electric push rod for driving the movement of the cross lifting linkage is located inside the storage box and is connected to the cross lifting linkage.

[0018] By adopting the above scheme, controlling the operation of the electric push rod can drive the cross lifting linkage to move, and the movement of the cross lifting linkage can push the support plate to move, thereby adjusting the up and down position of the support plate.

[0019] Preferably, the horizontal railing and side railing are provided with corresponding threaded holes in an array, which are used to thread the horizontal railing for protection.

[0020] By adopting the above solution, after the connecting plate is unfolded, it will drive the side railing to move synchronously. After the side railing moves to the predetermined position, the crossbar can be threadedly connected through the threaded hole to protect the gap between the side railing and the crossbar.

[0021] Preferably, the adjusting block is symmetrically provided with guide grooves, the movable box is fixedly provided with a guide plate corresponding to the guide groove, and the guide plate is engaged with the guide groove. The front of the concave frame is fixedly provided with a controller, the horizontal rail is provided with a connecting groove, a protective plate is inserted through the connecting groove, and the other end of the protective plate is fixedly connected to the side rail.

[0022] By adopting the above scheme, when adjusting the position of the adjusting block, the guide groove and guide plate work together to guide the adjusting block and make it move smoothly. After the connecting plate is unfolded, the side railing will drive the protective plate to slide in the connecting groove. The two work together to guide the connecting plate and make it move smoothly.

[0023] Preferably, the support plate is provided with a movable groove, a sliding block is engaged in the movable groove, and the sliding block is fixedly connected to the bottom of the support block. A cylinder is provided inside the sliding block, and a connecting shaft passes through the cylinder. A first electromagnet is fixedly provided inside the sliding block and is located on one side of the connecting shaft. A traction rope is fixedly connected to one end of the connecting shaft. A square frame is fixedly provided inside the movable groove, a limit cylinder is fixedly provided on the square frame, a first rotating wheel is provided inside the square frame, and the traction rope passes around the first rotating wheel. A sliding groove is provided inside the support plate, and one end of the traction rope passes through the sliding groove.

[0024] By adopting the above scheme, when the position of the support block is adjusted, the No. 1 electromagnet generates a strong magnet, which positions the connecting shaft. The movement of the support block can drive the traction rope to move through the sliding block and the connecting shaft. The No. 1 rotating wheel, the limiting cylinder and the slide groove will drive the traction rope to move smoothly. Conversely, when the No. 1 electromagnet stops working, it no longer generates a strong magnet and no longer positions the connecting shaft. When the support block moves and drives the sliding block to move, it will drive the cylinder to move. The movement of the cylinder will not pull the connecting shaft to move, and thus will not drive the traction rope to move.

[0025] Preferably, the support plate is symmetrically provided with a frame, the frame is provided with a groove, a second rotating wheel is rotatably provided in the groove, a guide ring is fixedly provided in the frame, and the traction rope passes through the guide ring after passing around the second rotating wheel. The frame is symmetrically provided with a strip groove, a limit rod is fixedly provided in the strip groove, a return spring is surrounded on the limit rod, a sliding seat is engaged on the frame, and the limit rod passes through the sliding seat. A pull block is fixedly connected in the sliding seat, and the pull block is fixedly connected to the other end of the traction rope. The sliding seat is symmetrically provided with limit holes, a counterweight is provided on the sliding seat, a limit shaft is provided on the counterweight, and the limit shaft engages with the corresponding limit hole. A second electromagnet is embedded in the frame in an array, and the second electromagnet is located below the sliding seat.

[0026] By adopting the above scheme, the movement of the traction rope is assisted by the cooperation of the second rotating wheel and the guide ring. The movement of the traction rope, via the pull block, drives the sliding seat to move. The limit rod guides the sliding seat, ensuring its smooth movement. The movement of the sliding seat causes the counterweight to move. Once the sliding seat is adjusted to the predetermined position, the second electromagnet generates a strong magnet to fix the sliding seat in place. Simultaneously, the first electromagnet stops working and no longer pulls the traction rope, thus ceasing further adjustment of the sliding seat's position. By adjusting the position of the counterweight, the center of gravity can be flexibly adjusted, allowing for flexible changes to the work platform. The overall center of gravity distribution effectively balances the overturning moment generated by the outward cantilever of the platform, improving structural stability under edge-adjacent working conditions and reducing the safety risk of high-altitude overturning. At the same time, the center of gravity can be dynamically adapted according to the platform's expansion area, personnel, and material stacking positions, eliminating the need for additional diagonal support components. This better adapts to different construction conditions and broadens the platform's application range. When the counterweight is no longer needed, the No. 2 electromagnet stops working, and the sliding seat can be moved manually. It can be reset by a return spring, which can assist personnel in pushing the sliding seat back to its original position. After the sliding seat is reset, the No. 2 electromagnet is controlled to generate a strong magnet, which can reposition the sliding seat.

[0027] The beneficial effects of this invention are as follows: 1. The foldable edge-operated platform for high-rise building curtain wall construction described in this invention expands the working area by using a dual-shaft motor to drive the adjusting screws to rotate. The two sets of screws have opposite threads, allowing for synchronous adjustment of the adjusting block position during rotation. The adjusting block is guided by a guide groove and guide plate, ensuring smooth movement. The adjusting block causes the connecting plate to extend from the storage groove. During the unfolding of the connecting plate, the side railings drive the protective plate to slide along the connecting groove, ensuring smooth guidance of the connecting plate. Once the connecting plate is fully extended and locked, the working platform area can be expanded. Simultaneously, the side railings move synchronously with the connecting plate. After reaching the desired position, a crossbar can be installed through the threaded hole to close the protective gap between the side railings and the crossbar. When there is no need to expand the working area, the connecting plate can be folded and stored, effectively reducing the platform's space occupation and minimizing interference with facade construction. This allows for flexible adjustment of the working area, balancing practicality and space efficiency.

[0028] 2. The foldable edge protection platform for high-rise building curtain wall construction described in this invention allows the platform to be continuously protected against unfinished floor edges by means of side railings and horizontal railings after work is suspended and folded up. This eliminates the need for a separate steel pipe edge protection system, thus eliminating the risks of high-altitude operations caused by the erection and dismantling of protective facilities, avoiding unprotected gaps at edge openings, and ensuring that the railings are integrated components of the platform, making them difficult for construction workers to disassemble in parts without authorization. This provides stronger protection stability, reduces the input of turnover materials such as steel pipes and fasteners, simplifies on-site construction procedures, and realizes the integrated reuse of the curtain wall construction platform and the floor edge safety protection.

[0029] 3. The foldable edge-operated platform for high-rise building curtain wall construction described in this invention, when carrying out curtain wall construction work, drives the adjustment mechanism to adjust the position of the support block. The support block, through the storage box, drives the support plate, horizontal railing and side railing to move outward and out of the floor at the same time. After the front and rear positions are adjusted to the correct position, the support plate can provide a working surface for construction personnel, meeting the needs of high-rise building curtain wall construction. At the same time, the vertical height of the support plate can be adjusted with the help of the adjustment components, realizing flexible control of the working position and effectively improving the adaptability and flexibility of the equipment.

[0030] 4. The foldable edge-operating platform for high-rise building curtain wall construction described in this invention, when the traction rope moves, drives the sliding seat to slide via the pull block. The guide structure ensures the smooth operation of the sliding seat. During the movement of the sliding seat, the counterweight block is simultaneously displaced. After the sliding seat is adjusted to the target position, the second electromagnet is energized to generate magnetic force to lock the sliding seat in place. At the same time, the first electromagnet stops working, releasing the traction of the traction rope and ending the counterweight position adjustment. By adjusting the position of the counterweight block through this mechanism, the overall center of gravity distribution of the operating platform can be flexibly changed, effectively counteracting the overturning moment formed by the outward cantilever of the platform, improving the structural stability during edge operations, reducing the risk of high-altitude overturning, and dynamically matching the center of gravity according to the platform's expansion area, personnel positioning, and material stacking. No additional diagonal support components are required, making it suitable for various curtain wall construction conditions and broadening the applicable scenarios of the equipment.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figures 1 to 11As shown in the embodiment of the present invention, a foldable edge-operating platform for high-rise building curtain wall construction includes a bearing plate 1, a positioning block 2 fixedly installed on the side of the bearing plate 1, a concave frame 3 fixedly installed on the bearing plate 1, a support block 4 passing through the concave frame 3, an adjustment mechanism for adjusting the position of the support block 4 provided in the concave frame 3, a storage box 5 fixedly installed on the support block 4, a support plate 19 installed on the top of the storage box 5, an adjustment component for adjusting the vertical position of the support plate 19 provided in the storage box 5, a storage groove 21 provided in the support plate 19, and a connecting rod passing through the storage groove 21. A side railing 23 is fixedly installed on the connecting plate 22, and a horizontal railing 20 is fixedly installed on the support plate 19. A movable box 25 is fixedly installed at the bottom of the support plate 19, and the movable box 25 is connected to the storage slot 21. A support frame 26 is fixedly installed inside the movable box 25, and a dual-output shaft motor 27 is fixedly installed inside the support frame 26. An adjusting screw 28 is rotatably installed inside the movable box 25, and the end of the adjusting screw 28 is fixedly connected to the output end of the dual-output shaft motor 27. An adjusting block 29 is fixedly connected to the bottom of the connecting plate 22, and the outer surface of the adjusting screw 28 is threadedly connected to the inside of the adjusting block 29.

[0036] When using a foldable edge protection platform for high-rise building curtain wall construction to provide working space for workers, installation points corresponding to positioning blocks 2 are pre-set on the floor. Bolts are used to engage with positioning blocks 2 to position the bearing plate 1, thereby positioning and installing the foldable edge protection platform for high-rise building curtain wall construction. When not in use, the platform is folded, and the side railings 23 and horizontal railings 20 provide protection for the side of the floor that has not been completed. There is no need to set up a separate steel pipe edge protection system, eliminating the risks of high-altitude operations caused by the erection and dismantling of protective structures and the gap period without edge protection. Moreover, the railings are linked components of the platform body and are not easily dismantled by workers, resulting in higher protection reliability. At the same time, it reduces the input of turnover materials such as steel pipes and fasteners, simplifies on-site construction procedures, and realizes the integrated reuse of the curtain wall operation platform and the floor edge protection.

[0037] The controller 32 is electrically connected to the electronic equipment on the foldable edge-operated platform for high-rise building curtain wall construction. It can control the operation of the electronic equipment and, during curtain wall construction, control the movement of the adjustment mechanism to adjust the position of the support block 4. The support block 4 can drive the support plate 19, the horizontal railing 20, and the side railing 23 to move synchronously through the storage box 5, thereby moving it out of the floor. After the front and back positions are adjusted to the predetermined positions, the support plate 19 provides working space for the workers, facilitating the construction of the high-rise building curtain wall. Through the adjustment components, the vertical position of the support plate 19 can be adjusted, thereby achieving the purpose of flexibly adjusting the working position and improving flexibility.

[0038] When expanding the working area, controlling the dual-shaft motor 27 will drive the adjusting screw 28 to rotate. The threads on the two sets of adjusting screws 28 are opposite, and the rotation of the adjusting screw 28 will adjust the position of the adjusting block 29. When the adjusting block 29 moves, it will also drive the connecting plate 22 to move. After the connecting plate 22 moves from the storage slot 21 to the outside, the position of the connecting plate 22 is fixed, which can expand the working platform area. When not needed, the connecting plate 22 can be folded and stored to reduce the space occupied. This can expand the effective working area of ​​the working platform and meet the needs of multiple people working at the same time and temporary material storage. When not in use, the connecting plate 22 can be folded and stored to reduce the overall space occupied by the platform, making it easy to store and place the platform, reducing interference with the external facade construction space, and realizing flexible adjustment of the working area, taking into account both construction practicality and space intensification.

[0039] Furthermore, a guide cylinder 6 is provided inside the support block 4, and a guide rod 7 is inserted inside the guide cylinder 6, with the other end of the guide rod 7 fixedly connected to the inner wall of the concave frame 3.

[0040] When adjusting the position of the support block 4, the guide cylinder 6 and the guide rod 7 work together to guide the support block 4, so that the support block 4 moves smoothly.

[0041] Furthermore, the adjustment mechanism includes a threaded screw 8, a power motor 9, a reducer 10, and pulleys 12. The threaded screw 8 is rotatably mounted inside the concave frame 3, and the outer surface of the threaded screw 8 is threadedly connected to the inside of the support block 4. The reducer 10 is fixed to the top of the concave frame 3, and the power motor 9 is fixed to the reducer 10. The output end of the power motor 9 is fixedly connected to the input end of the reducer 10. Both the threaded screw 8 and the output end of the reducer 10 are fixedly connected to pulleys 12, and the two sets of pulleys 12 are connected by belt drive.

[0042] The operation of the control motor 9 will drive the reducer 10 to move. When the reducer 10 moves, it will drive the threaded screw 8 to rotate through the cooperation of two sets of pulleys 12. When the threaded screw 8 rotates, it will adjust the position of the support block 4, thereby adjusting the front and rear position of the storage box 5.

[0043] Furthermore, a protective cover 11 is fixedly installed on the side of the concave frame 3, and the protective cover 11 is located on one side of the pulley 12.

[0044] The protective cover 11 is used to protect the pulley 12, effectively preventing external factors from affecting the transmission of the pulley 12.

[0045] Furthermore, the concave frame 3 is symmetrically provided with locking blocks 13, and the support block 4 is fixedly provided with a locking groove 16 corresponding to the locking block 13, and the locking block 13 engages with the corresponding locking groove 16. The top of the locking block 13 is provided with an installation groove 14, and the installation groove 14 is provided with an array of support wheels 15.

[0046] When the position of the support block 4 is adjusted, the slot 16 will move. Through the cooperation of the slot 13 and the slot 16, the support block 4 will be further guided, so that the support block 4 moves smoothly. The top of the support wheel 15 supports the top of the inner wall of the slot 16. The support wheel 15 facilitates the movement of the slot 16, so that the support block 4 moves smoothly.

[0047] Furthermore, the adjustment assembly includes a cross lifting link 17 and an electric push rod 18. The cross lifting link 17 is located inside the storage box 5 and is connected to the bottom of the support plate 19. The electric push rod 18, which drives the cross lifting link 17, is located inside the storage box 5 and is connected to the cross lifting link 17.

[0048] The operation of the electric push rod 18 can drive the cross lifting link 17 to move, and the movement of the cross lifting link 17 can push the support plate 19 to move, thereby adjusting the vertical position of the support plate 19.

[0049] Furthermore, the horizontal railing 20 and the side railing 23 are provided with corresponding threaded holes 24, which are used for threaded connection of the horizontal railing for protection.

[0050] After the connecting plate 22 is unfolded, it will drive the side railing 23 to move synchronously. After the side railing 23 moves to the predetermined position, the crossbar can be threadedly connected through the threaded hole 24 to protect the gap between the side railing 23 and the crossbar 20.

[0051] Furthermore, the adjusting block 29 is symmetrically provided with guide grooves 30, and the movable box 25 is fixedly provided with a guide plate 31 corresponding to the guide groove 30, and the guide plate 31 is engaged with the guide groove 30. The concave frame 3 is fixedly provided with a controller 32 on the front side, and the horizontal rail 20 is provided with a connecting groove 33. A protective plate 34 is inserted through the connecting groove 33, and the other end of the protective plate 34 is fixedly connected to the side rail 23.

[0052] When adjusting the position of the adjusting block 29, the adjusting block 29 is guided by the guide groove 30 and the guide plate 31, so that the adjusting block 29 moves smoothly. After the connecting plate 22 is unfolded, the protective plate 34 will slide in the connecting groove 33 by the side rail 23. The two work together to guide the connecting plate 22, so that the connecting plate 22 moves smoothly.

[0053] Furthermore, the support plate 1 is provided with a movable groove 35, a sliding block 36 is engaged in the movable groove 35, and the sliding block 36 is fixedly connected to the bottom of the support block 4. A cylinder 37 is provided in the sliding block 36, and a connecting shaft 38 passes through the cylinder 37. A first electromagnet 39 is fixedly provided in the sliding block 36, and the first electromagnet 39 is located on one side of the connecting shaft 38. A traction rope 40 is fixedly connected to one end of the connecting shaft 38. A square frame 41 is fixedly provided in the movable groove 35, a limit cylinder 42 is fixedly provided on the square frame 41, a first rotating wheel 43 is provided in the square frame 41, and the traction rope 40 passes around the first rotating wheel 43. A sliding groove 44 is provided in the support plate 1, and one end of the traction rope 40 passes through the sliding groove 44.

[0054] When the position of the support block 4 is adjusted, the first electromagnet 39 generates a strong magnet, which positions the connecting shaft 38. The movement of the support block 4, through the sliding block 36 and the connecting shaft 38, can drive the traction rope 40 to move. Through the first rotating wheel 43, the limiting cylinder 42 and the slide groove 44, the traction rope 40 will move smoothly. Conversely, when the first electromagnet 39 stops working, it no longer generates a strong magnet and no longer positions the connecting shaft 38. When the support block 4 moves and drives the sliding block 36 to move, it will drive the cylinder 37 to move. The movement of the cylinder 37 will not pull the connecting shaft 38 to move, and thus will not drive the traction rope 40 to move.

[0055] Furthermore, a frame 45 is symmetrically arranged on the bearing plate 1, a groove 46 is provided inside the frame 45, a second rotating wheel 47 is rotatably arranged inside the groove 46, a guide ring 48 is fixedly arranged inside the frame 45, and the traction rope 40 passes through the guide ring 48 after passing around the second rotating wheel 47. A strip groove 49 is symmetrically arranged on the frame 45, a limit rod 50 is fixedly arranged inside the strip groove 49, a return spring 51 is arranged around the limit rod 50, and a sliding seat 52 is engaged on the frame 45. The limiting rod 50 passes through the sliding seat 52. A pull block 53 is fixedly connected inside the sliding seat 52, and the pull block 53 is fixedly connected to the other end of the traction rope 40. Limiting holes 54 are symmetrically arranged on the sliding seat 52. A counterweight 55 is arranged on the sliding seat 52. A limiting shaft 56 is arranged on the counterweight 55, and the limiting shaft 56 engages with the corresponding limiting hole 54. A second electromagnet 57 is arrayed and embedded inside the frame 45, and the second electromagnet 57 is located below the sliding seat 52.

[0056] When the traction rope 40 moves, it is assisted by the No. 2 rotating wheel 47 and the guide ring 48. When the traction rope 40 moves, it drives the sliding seat 52 to move through the pull block 53. The limit rod 50 guides the sliding seat 52 to move smoothly. When the sliding seat 52 moves, it drives the counterweight block 55 to move. After the sliding seat 52 is adjusted to the predetermined position, the No. 2 electromagnet 57 generates a strong magnet to position the sliding seat 52. At the same time, the No. 1 electromagnet 39 stops working and no longer pulls the traction rope 40 to move, and thus no longer adjusts the position of the sliding seat 52. By adjusting the position of the counterweight block 55, the center of gravity position can be flexibly adjusted, which can flexibly change the overall center of gravity distribution of the working platform, effectively balance the overturning moment generated by the outward cantilever of the platform, improve the structural stability in the edge working state, reduce the safety risk of high-altitude overturning, and can dynamically adapt the center of gravity according to the platform expansion area, personnel and material stacking position, without the need to add additional diagonal support components, better adapt to different construction conditions, and broaden the platform's application range. Furthermore, different numbers of counterweights 55 can be pre-installed for counterweighting via the limiting shaft 56, and the bottom of the sliding seat 52 can be pre-set with traveling wheels. The traveling wheels contact the inner wall of the frame 47, which can effectively assist the sliding seat 52 to move smoothly. When the counterweight is no longer needed, the second electromagnet 57 stops working, and the sliding seat 52 can be moved manually. It is then reset by the return spring 51. The sliding seat 52 can be reset by the manual pusher. After the sliding seat 52 is reset, the second electromagnet 57 is controlled to generate a strong magnet, which can reposition the sliding seat 52.

[0057] Working Principle: First, during high-rise curtain wall construction, when using the foldable edge-protection platform for high-rise building curtain wall construction to provide working space for workers, installation points corresponding to positioning blocks 2 are pre-set on the floor. Bolts are used in conjunction with positioning blocks 2 to position the bearing plate 1, thereby positioning and installing the foldable edge-protection platform for high-rise building curtain wall construction. When not in use, the platform folds up, and the side railings 23 and horizontal railings 20 provide protection for the unfinished side of the floor. There is no need to erect a separate steel pipe edge protection system, eliminating the risks of high-altitude operations caused by the erection and dismantling of protective measures, as well as the gap period without edge protection. Furthermore, the railings are linked components of the platform body, making them difficult for workers to dismantle independently, resulting in higher reliability of protection and reducing costs. This reduces the input of reusable materials such as steel pipes and fasteners, simplifies on-site construction procedures, and achieves integrated reuse of the curtain wall operation platform and floor edge protection. During curtain wall construction, the operation of the control motor 9 drives the reducer 10. When the reducer 10 moves, it drives the threaded screw 8 to rotate through the cooperation of two sets of pulleys 12. When the threaded screw 8 rotates, it adjusts the position of the support block 4, which in turn allows for the adjustment of the front and rear position of the storage box 5. Through the storage box 5, the support plate 19, the horizontal railing 20, and the side railing 23 can be moved synchronously, thus moving them out of the floor. After the front and rear positions are adjusted to the predetermined positions, the support plate 19 provides working space for the workers, facilitating the construction of the curtain wall of high-rise buildings. Controlling the operation of the electric push rod 18 can drive the cross lifting linkage 17 to move. The movement of the cross lifting linkage 17 can push the support plate 19 to move, thereby adjusting the vertical position of the support plate 19 and achieving flexible adjustment of the working position, improving flexibility. When expanding the working area, controlling the dual-output shaft motor 27 will drive the adjusting screw 28 to rotate. The threads on the two sets of adjusting screws 28 are opposite, so the rotation of the adjusting screw 28 will adjust the position of the adjusting block 29. When the adjusting block 29 moves, it will also drive the connecting plate 22 to move. When adjusting the position of the adjusting block 29, the guide groove 30 and the guide plate 31 cooperate to guide the adjusting block 29, so that the adjusting block 29 moves smoothly. After the connecting plate 22 is unfolded, the side rail 23 will drive the protective plate 34 to slide in the connecting groove 33. The two cooperate to protect the connecting plate 22. The guide plate 22 moves smoothly from the storage slot 21 to the outside. After the connecting plate 22 is moved and its position is fixed, the working platform area can be expanded. When the connecting plate 22 is unfolded, it will drive the side rails 23 to move synchronously. After the side rails 23 move to the predetermined position, they can be threaded to the crossbars through the threaded holes 24 to protect the gap between the side rails 23 and the crossbars 20. When not needed, the connecting plate 22 can be folded and stored to reduce the space occupied, thereby expanding the effective working area of ​​the working platform and meeting the needs of multiple people working at the same time and temporary material storage. When not in use, the connecting plate 22 can be folded and stored to reduce the overall space occupied by the platform, making it easy to store and place the platform and reducing interference with the external construction space.The working area can be flexibly adjusted, taking into account both construction practicality and space efficiency. When the position of the support block 4 is adjusted, the first electromagnet 39 generates a strong magnet, which positions the connecting shaft 38. The movement of the support block 4, through the sliding block 36 and the connecting shaft 38, can drive the traction rope 40 to move. Through the first rotating wheel 43, the limiting cylinder 42, and the slide groove 44, the traction rope 40 will move smoothly. When the traction rope 40 moves, the second rotating wheel 47 and the guide ring 48 will assist the movement of the traction rope 40. When the traction rope 40 moves, it will drive the sliding seat 52 to move through the pull block 53. The limiting rod 50 will guide the sliding seat 52 to move smoothly. When the sliding seat 52 moves, it will drive the counterweight block. After the sliding seat 52 is adjusted to the predetermined position by moving the counterweight 55, the second electromagnet 57 generates a strong magnet to position the sliding seat 52. At the same time, the first electromagnet 39 stops working and no longer pulls the traction rope 40, thus ceasing to adjust the position of the sliding seat 52. By adjusting the position of the counterweight 55, the center of gravity can be flexibly adjusted, allowing for flexible changes in the overall center of gravity distribution of the work platform. This effectively balances the overturning moment generated by the outward cantilever of the platform, improving structural stability under edge-prone working conditions, reducing the safety risk of high-altitude overturning, and dynamically adapting the center of gravity according to the platform's expansion area, personnel, and material stacking location without the need for additional diagonal support components. This better adapts to different construction conditions and broadens the platform's applicability.
