Description

Technical Field

[0001] This invention belongs to the field of high-altitude work tools, specifically relating to a wind-resistant suspended platform for high-rise building exterior wall construction. Background Technology

[0002] In the modern construction industry, high-rise and super high-rise buildings are constantly emerging. Construction scaffolding, as a common piece of equipment for exterior wall construction, decoration, and maintenance of high-rise buildings, is widely used due to its flexibility and convenience. However, in actual use, the safety and stability of scaffolding has always been a key concern in the industry. Especially in windy weather, the swaying of scaffolding seriously threatens the lives of construction workers and also affects construction progress and project quality. To reduce the wind resistance and stability of scaffolding during high-altitude operations, minimize economic losses, prevent personnel injuries and fatalities, and improve the safety of scaffolding operations, it is necessary to develop wind-resistant scaffolding for high-rise building exterior wall construction.

[0010] Furthermore, the upper triggering structure includes a support cylinder, a moving rod, a triggering rod, a first spring, a pressure ring, and a triggering arc plate. The support cylinder is horizontally connected to the side wall of the locking box and located beside the wire rope. The pressure ring is located on the moving rod.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] This invention provides a wind-resistant suspended platform for high-rise building exterior wall construction. Through a dual upper and lower wind sway sensing and mechanical locking system, it achieves rapid and effective suppression of severe swaying of the platform in strong winds, instantly transforming the flexible suspension system into a near-rigid support, greatly improving the safety, stability, and reliability of high-rise exterior wall construction operations. Simultaneously, a synchronous adjustment structure ensures the stability of the platform's posture. The overall design is ingenious, responsive, and reliable.

[0016] Through a coordinated upper and lower locking mechanism, the flexible wire rope system is transformed into a near-rigid support structure. When the upper triggering structure senses abnormal swaying of the upper wire rope (usually caused by wind), the upper locking structure (ratchet and pawl) quickly activates, locking the upper wire rope to prevent it from sliding down from the crane or exacerbating the swaying, thus stabilizing the top of the suspended platform. When the lower triggering structure senses abnormal swaying of the lower wire rope, the lower locking structure (first and second rotating rollers pressing) immediately locks the lower wire rope, preventing it from slackening or swaying. The simultaneous activation of the upper and lower locking structures instantly tensions and fixes the ropes connecting the top (upper wire rope) and bottom (lower wire rope) of the suspended platform, transforming the entire suspended platform system from flexible to rigid. This significantly restricts the degree of freedom of the suspended platform under wind loads, substantially reducing the sway amplitude and sway energy, providing a more stable and safer platform for workers at height, and reducing the risk of falls and psychological stress.

Detailed Implementation

[0035] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0036] like Figure 1 , Figure 2 , Figure 13 As shown: A wind-resistant suspended platform for the construction of the exterior wall of a high-rise building includes a suspended platform 1, with two upper steel wire ropes 11 for lifting at the top of the suspended platform 1 and two lower steel wire ropes 12 for tensioning at the bottom of the suspended platform 1.

[0037] The lower end of the upper wire rope 11 is divided into two branches, which are connected to two hoisting points of the suspended basket 1. A synchronous adjustment structure 2 for pulling and limiting is provided between the two branches of the upper wire rope 11, and the branches of the upper wire rope 11 pass through the synchronous adjustment structure 2.

[0038] It also includes two cranes 3, which are located on the roof of the high-rise building. The upper wire rope 11 is connected to the crane 3. The crane 3 is equipped with an upper locking structure 4 to lock the upper wire rope 11. The upper wire rope 11 passes through the upper locking structure 4. The upper locking structure 4 is equipped with an upper triggering structure 5 to sense the swing of the upper wire rope 11.

[0039] It also includes two rope winding mechanisms 6 set on the ground. The two rope winding mechanisms 6 are respectively connected to two lower steel wire ropes 12. The rope winding mechanism 6 is provided with a lower locking structure 7 to lock the lower steel wire rope 12. The lower steel wire rope 12 passes through the lower locking structure 7. The lower locking structure 7 is provided with a lower triggering structure 8 to sense the swing of the lower steel wire rope 12.

[0040] During high-rise construction, the crane 3 and the rope winding mechanism 6 move in sync to achieve vertical transportation. The crane 3 pulls the upper wire rope 11 to drive the suspended basket 1 to rise and fall vertically along the wall, while the rope winding mechanism 6 simultaneously raises and lowers the wire rope 12 to meet the needs of vertical transportation of construction personnel, tools and materials.

[0041] When the upper wire rope 11 swings and triggers the upper triggering structure 5, the upper locking structure 4 will lock the upper wire rope 11 to prevent it from falling from the hoist 3, thereby reducing the sway of the suspended basket 1. When the lower wire rope 12 swings and triggers the lower triggering structure 8, the lower locking structure 7 will lock the lower wire rope 12. The upper wire rope 11 at the top of the suspended basket and the lower wire rope 12 at the bottom are simultaneously tensioned, and the flexible rope becomes a "steel rope" to reduce the sway of the suspended basket 1.

[0042] like Figure 3 , Figure 4 , Figure 5 As shown: The synchronous adjustment structure 2 includes a support rod 21, a mounting frame 22, an adjustment motor 23, two adjustment gear plates 24, and two wire rope tensioning assemblies 20. The support rod 21 is vertically installed on the top of the suspended basket 1, and the mounting frame 22 is horizontally installed on the top of the support rod 21. The adjustment motor 23 is located on the mounting frame 22. The main shaft of the adjustment motor 23 is equipped with an adjustment gear 26 and is located inside the mounting frame 22. The two adjustment gear plates 24 are respectively equipped with two slide rods 25. The slide rods 25 are slidably engaged with the mounting frame 22. The two adjustment gear plates 24 are slidably connected inside the mounting frame 22 and mesh with the adjustment gears 26. The two wire rope tensioning assemblies 20 are respectively connected to the two slide rods 25.

[0043] like Figure 6 , Figure 7 As shown: The wire rope tensioning assembly 20 includes a mounting cylinder 201 horizontally connected to the end of the slide bar 25. A rotary motor 202 is provided inside the mounting cylinder 201. A rotary cylinder 203 is provided on the main shaft of the rotary motor 202. An adjusting frame 204 is connected to the rotary cylinder 203. Two tensioning rollers 205 are provided inside the adjusting frame 204. A branch of the upper wire rope 11 passes through the two tensioning rollers 205.

[0044] The synchronous adjustment structure 2 ensures the synchronization of the two upper wire ropes, maintaining the horizontal stability of the suspended platform 1. The synchronous adjustment structure 2 can actively adjust the tension of the two upper wire rope branches, ensuring that the upper wire ropes 11 on both sides of the suspended platform 1 are of consistent length and evenly stressed. Even when strong winds cause uneven stress on both sides of the suspended platform 1 or minor differences occur during normal use, the tensioning assembly can be dynamically compensated by adjusting the motor 23 to drive its movement, always maintaining the horizontal state of the top of the suspended platform and preventing the suspended platform 1 from tilting due to slack on one side of the wire rope, further enhancing overall stability and safety. The wire rope tensioning assembly 20 (with tensioning rollers alternately pressing the wire rope) not only provides an adjustment fulcrum, but its friction also helps to suppress minor movement of the wire rope during the adjustment process.

[0045] like Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown: The upper locking structure 4 includes a locking box 41, a rotating roller 42, a drive cylinder 43, a ratchet 44, a pawl 45, and a rotating shaft 46. The locking box 41 is located on the hoist 3. The rotating roller 42 is rotatably connected to the locking box 41 via the rotating shaft 46. The ratchet 44 is connected to the end of the rotating shaft 46 and is located on the outside of the locking box 41. The pawl 45 is rotatably connected to the side wall of the locking box 41 at its middle position. The pawl 45 can engage with the ratchet 44 to lock it. The tail end of the drive cylinder 43 is hinged to the side wall of the locking box 41. The extension end of the drive cylinder 43 is provided with a drive block 47, which is hinged to the pawl 45. The upper wire rope 11 is wound on the rotating roller 42. The hoist 3 can drive the roller 42 to rotate, thereby winding and unwinding the upper wire rope 11. The height of the suspended basket 1 is controlled to meet construction requirements.

[0046] like Figure 12 As shown: The upper trigger structure 5 includes a support cylinder 51, a moving rod 52, a trigger rod 53, a first spring 54, a pressure ring 55, and a trigger arc plate 56. The support cylinder 51 is horizontally connected to the side wall of the locking box 41 and located beside the wire rope 11. The pressure ring 55 is located on the moving rod 52. The trigger arc plate 56 is located at one end of the moving rod 52. The first spring 54 is supported between the support cylinder 51 and the pressure ring 55. The trigger rod 53 is connected to the other end of the moving rod 52. A first trigger switch 57 is provided inside the support cylinder 51. The first trigger switch 57 serves as the start switch for driving the electric cylinder 43.

[0047] When the suspended platform 1 shakes, it will cause the upper wire rope 11 to swing. When the upper wire rope 11 swings left and right, it will hit the trigger arc plate 56. The trigger arc plate 56 will push the moving rod 52 to move horizontally in the support cylinder 51. The trigger rod 53 at the end of the moving rod 52 will collide with the first trigger switch 57. The first trigger switch 57 will control the drive cylinder 43 to be energized and work. The drive cylinder 43 operates to rotate the pawl 45, which abuts against the ratchet 44, thus restricting the rotation of the ratchet 44. The rotating roller 42, which is coaxial with the ratchet 44, is also locked, and the upper wire rope 11 is locked. This prevents the suspended basket 1 from falling due to the slippage of the upper wire rope 11. The locking structure rigidly fixes the upper wire rope 11, ensuring that the crane 3 and the drum brake synchronously, avoiding the fatal risk caused by "rope slippage". The locking structure can quickly respond to the displacement of the upper wire rope 11 caused by wind, preventing the suspended basket 1 from hitting the building facade or adjacent structures like a "pendulum", avoiding secondary disasters such as personnel injury and structural damage to the suspended basket 1.

[0048] like Figure 16 As shown: The first trigger switch 57 includes a fixed cap 571, a movable cap 572, a blade 573, and a wire 574. The fixed cap 571 and the movable cap 572 are slidably sleeved together. The fixed cap 571 is mounted on the support cylinder 51, and the movable cap 572 faces the trigger rod 53. The first trigger switch 57 is connected in parallel with the drive cylinder 43. The drive cylinder 43 is connected in series with a resistor 575. The wire 574 passes through the fixed cap 571 and is connected to the parallel circuit. The wire 574 inside the fixed cap 571 is taut and suspended. The blade 573 is mounted on the movable cap 572, and the blade edge of the blade 573 faces the wire 574. When the upper trigger structure 5 is in a stationary state, the first trigger switch 57 is in the closed state, and the first trigger switch 57 short-circuits the drive cylinder 43, so the drive cylinder 43 does not work. When the trigger rod 53 collides with the movable cap 572, the movable cap 572 moves deeper into the fixed cap 571, and the blade 573 cuts the wire 574. The taut wire 574 is disconnected. At this time, the first trigger switch 57 is in the open state, and the drive cylinder 43 is energized and works. The first trigger switch 57 provides a physical circuit breaking triggering method by using the blade 573 to cut the wire 574.

[0049] like Figure 12 , Figure 14As shown: The lower locking structure 7 includes a first rotating roller 71, a second rotating roller 72, and two mounting seats 73. The two mounting seats 73 are located on the top of the rope winding mechanism 6. The two mounting seats 73 are provided with grooves 74. The two ends of the first rotating roller 71 are rotatably connected to the two mounting seats 73. Each groove 74 is provided with a sliding block 75. The two ends of the second rotating roller 72 are rotatably connected to the two sliding blocks 75. Each mounting seat 73 is provided with a locking electric cylinder 76 on its side wall. The tail end of the locking electric cylinder 76 is fixedly connected to the mounting seat 73. The telescopic end of the locking electric cylinder 76 is connected to the sliding block 75. The lower wire rope 12 is located between the first rotating roller 71 and the second rotating roller 72.

[0050] like Figure 15 As shown: The lower trigger structure 8 includes a placement frame 81 disposed between two mounting seats 73. The placement frame 81 is located below the first rotating roller 71 and the second rotating roller 72. The outer wall of the placement frame 81 is provided with a placement frame 82. The placement frame 81 is provided with a sliding rod 83 that is slidably engaged. The sliding rod 83 is provided with a trigger plate 84. A second spring 85 is provided between the sliding rod 83 and the placement frame 81. The sliding rod 83 is provided with a trigger post 86. The placement frame 82 is provided with a second trigger switch 87, which serves as the start switch for the locking electric cylinder 76.

[0051] The upper triggering structure 5 and the lower triggering structure 8 adopt a mechanical triggering mechanism based on spring displacement, which can automatically and in real time sense abnormal swing (wind sway signal) of the upper wire rope 11 and the lower wire rope 12. The sensing signal automatically triggers the corresponding upper locking structure 4 and lower locking structure 7. The drive cylinder 43 in the upper locking structure 4 is energized to push the pawl 45 to lock the ratchet 44, and the locking cylinder 76 in the lower locking structure 7 is energized to push the second rotating roller 72 to press the lower wire rope 12. The closed-loop process of sensing-triggering-locking is completed automatically without manual intervention. It has a fast response speed and can suppress the sway in the early stage of wind sway, effectively preventing the sway from aggravating and greatly improving the reliability and safety of the system in severe weather.

[0052] The upper locking structure 4 uses a ratchet and pawl mechanism with an electric cylinder drive, a mechanical self-locking method. Once locked, it cannot move in the opposite direction (fall) unless manually released, ensuring high reliability and preventing the significant risk of the suspended basket 1 falling due to uncontrolled upper rope. The lower locking structure 7 uses a movable roller to press the wire rope, providing strong positive pressure through a locking electric cylinder, using friction to lock the lower wire rope 12, preventing it from being pulled out or slackening. This structure is simple and effective, and can quickly respond to locking commands. The two independent locking systems complement each other, forming a robust defense against wind.

[0053] like Figure 17As shown: The structure of the second trigger switch 87 is the same as that of the first trigger switch 57. Two locking electric cylinders 76 and a resistor 575 are connected in series, and the second trigger switch 87 is connected in parallel with the two locking electric cylinders 76. When the second trigger switch 87 is in the closed state, the two locking electric cylinders 76 are short-circuited and do not work. The trigger pin 86 hits the second trigger switch 87. After the second trigger switch 87 cuts the internal wire, the two locking electric cylinders 76 are energized and work.

[0054] When the suspended platform 1 sways, it will also cause the lower wire rope 12 to swing left and right. The lower wire rope 12 will collide with the trigger plate 84. After being subjected to force, the trigger plate 84 will move to one side, pushing the sliding rod 83 to move on the placement frame 81. The trigger post 86 at the end of the sliding rod 83 will collide with the second trigger switch 87. The second trigger switch 87 controls the two locking electric cylinders 76 to be energized and work. The second trigger switch 87 adopts a physical circuit breaking triggering method. After being triggered, it must be manually restored to improve safety.

[0055] When the two locking electric cylinders 76 work simultaneously, they drive the two sliders 75 to move within the two sliding grooves 74 respectively, thereby moving the second rotating roller 72 towards the first rotating roller 71. The second rotating roller 72 and the first rotating roller 71 lock the lower wire rope 12, preventing the lower wire rope 12 from moving on the drum of the rope winding mechanism 6. When the suspended platform 1 swings, this structure can quickly lock the lower wire rope 12 to prevent it from sliding on the drum of the rope winding mechanism 6, thus avoiding the increased swaying amplitude of the suspended platform 1 due to the displacement of the lower wire rope 12. By rigidly fixing the lower wire rope 11, the transmission of swing energy is limited, reducing the instability of the suspended platform 1 caused by centrifugal force or wind force. In response to sudden swaying, the locking structure can brake in time to prevent the swaying from continuing to expand, providing a more stable working environment for operators, reducing the risk of operational errors caused by swaying, and improving the safety and efficiency of high-altitude operations.
