Description

Technical Field

[0001] This invention belongs to the field of suspended platform stability assistance technology, and more specifically, relates to a suspended platform stability assistance system. Background Technology

[0002] A suspended platform is a commonly used suspended work platform in construction, typically constructed of steel or aluminum alloy. It can be suspended from and vertically moved along the exterior facade of a building. Equipped with an electric lifting system, the platform can move up and down the building's exterior wall, providing a working platform for construction workers at height. Its main function is for exterior work on high-rise buildings, such as cleaning, maintenance, painting, and window installation. With the advancement of urbanization and the proliferation of high-rise buildings, the requirements for efficiency and safety in construction are increasingly stringent. The use of suspended platforms meets the demands of modern construction for efficiency, precision, and safety. In cities with a high density of high-rise buildings, traditional construction methods are insufficient to meet the requirements of rapid and high-quality construction. Suspended platforms offer a solution, helping the construction industry adapt to the rapidly evolving needs of society. The exterior facade construction of high-rise buildings is challenging, and traditional scaffolding or hoisting equipment cannot meet the demands. Suspended platforms can move vertically along the building's exterior wall, directly reaching the construction area, improving work efficiency and shortening the construction cycle.

[0003] However, uneven building surfaces can cause a series of problems for the placement and use of the suspended platform. An uneven surface may prevent the platform from providing even support, leading to instability. This increases the risk of tilting or swaying during operation, affecting worker safety. An uneven surface can also cause uneven load distribution when the platform bears the weight of the building. Some areas may experience excessive pressure, increasing the risk of structural deformation and potentially damaging both the platform and the building structure. Summary of the Invention

[0004] In view of this, the present invention provides a suspended platform stability auxiliary system, which can solve the problems of suspended platform instability caused by uneven working surface height and low safety factor due to insufficient stability of the suspended platform support.

[0005] This invention is implemented as follows:

[0006] This invention provides a suspended platform stability assistance system, comprising a support frame, a horizontal adjustment component, a counterweight component, and a braking component. The bottom of the support frame is fixed to any plane on the top of the building to provide stability support for the suspended platform. The horizontal adjustment component is provided at the bottom of the support frame to adjust the tilt angle of the support frame. One end of the counterweight component is fixedly connected to the suspended platform, forming a lever structure between them to balance the descent height and the loaded weight of the suspended platform to ensure its stability during operation. One end of the braking component is fixedly connected to the support frame, and the other end is connected to the suspended platform to perform emergency braking in case of abnormal operation of the suspended platform to ensure its safety during operation.

[0007] The technical effects of the suspended platform stability assistance system provided by this invention are as follows: By setting up a support frame, it can be fixed to the top of the building, providing stable support for the suspended platform and preventing it from swaying or tilting during use, thereby improving operational safety. The support frame can evenly distribute the load of the suspended platform, reducing local pressure on the building structure and lowering the risk of damage. The stable support frame allows the suspended platform to work steadily at high altitudes, improving the accuracy and efficiency of worker operations and shortening construction time. By setting up a horizontal adjustment component, the support frame can be kept stable, thus avoiding tilting or instability caused by slope, ensuring the stability of the suspended platform during high-altitude operations. By eliminating the influence of slope on the support frame, the safety risks caused by instability are reduced. At the same time, it can adapt to building surfaces with different slopes, expanding the application range and flexibility of the support frame. By setting up a counterweight component, the suspension platform's descent height and load weight can be balanced, preventing instability or swaying during operation, thereby improving operational safety. The counterweight component can adjust the counterweight according to the weight loaded on the suspended platform, adapting to different load conditions, thus enabling the suspended platform to operate stably. By installing braking components, the rapid descent of the suspended platform can be prevented, thus preventing accidental falls due to slippage or other malfunctions, thereby significantly improving the safety of workers and equipment; and effectively avoiding the potential risks caused by rapid falls.

[0008] Based on the above technical solution, the suspended platform stability auxiliary system of the present invention can be further improved as follows:

[0009] The support frame includes a main beam frame and a cantilever beam. The main beam frame is fixed at the top of the building, and the cantilever beam is fixedly connected to the main beam frame to extend outward to allow the suspended platform to adjust its distance from the building.

[0010] The main beam frame includes an inner ring frame, which is fixed to the planar position of the building by an inner fixing connection assembly; the inner ring frame has an octagonal structure; an outer ring frame is provided on the outside of the inner ring frame, and the outer ring frame is concentrically corresponding to the inner ring frame; the bottom of the outer ring frame is fixed with the horizontal adjustment assembly, which is used to adjust the tilt angle of the plane formed by the inner ring frame and the outer ring frame; the outer ring frame is fixed to the top of the building by an external fixing connection assembly.

[0011] The inner ring frame and the outer ring frame are fixedly connected by horizontal bars. The horizontal bars consist of three layers: upper, middle, and lower, which sequentially enhance the connection strength between the inner ring frame and the outer ring frame. Multiple diagonal bars are fixed between the three layers of horizontal bars. The connection angles between the diagonal bars and the inner ring frame, outer ring frame, and horizontal bars are all 45°, forming triangular structures between adjacent inner ring frames, outer ring frames, and horizontal bars to distribute the stress and ensure the structural stability of the support frame.

[0012] The beneficial effects of adopting the above-mentioned improved scheme are as follows: By setting an octagonal main beam frame, the corresponding supports on each side can be adjusted accordingly, achieving uniform load distribution, preventing excessive local pressure, protecting buildings and equipment, and providing stable support on irregular or sloping terrain, reducing the risk of the support frame tilting or sliding. By setting diagonal braces, the load can be effectively distributed and transferred, enhancing the overall stability of the support frame. The isosceles right triangle can effectively control the deformation of the support frame, preventing deformation or twisting caused by uneven load or external forces. The triangular structure can effectively distribute and transfer forces, making the force application more uniform and improving the overall mechanical performance of the structure.

[0013] Furthermore, both the inner ring frame and the outer ring frame are structures composed of square frames, and vertical rods and diagonal rods are fixed inside the square frames to enhance the stability of the inner ring frame and the outer ring frame.

[0014] The inner ring frame, the outer ring frame, the horizontal bar, and the diagonal bar are all made of aluminum alloy, and adjacent structures are fixedly connected by reinforcing bolts.

[0015] Furthermore, a tension member is fixed to the side of the main beam frame that is close to the interior of the building and away from the cantilever beam. The tension member includes a first winch motor, a guide ring, and a fixing rope. The first winch motor is fixed inside the building. The guide ring is disposed between the first winch motor and the main beam frame. One end of the fixing rope is fixed to the main beam frame, and the other end passes through the guide ring and is wound around the first winch motor. The first winch motor is used to apply a force towards the interior of the building to the main beam frame by stretching the fixing rope to ensure the stability of the cantilever beam.

[0016] The guide ring is fixed to the surface of the building by a bracket, and its height is the same as that of the first winch motor, so that the fixing rope is parallel to the top plane of the building between the guide ring and the first winch motor; the guide ring is inclined inside, and its inclination angle is the inclination angle between the center position of the main beam frame and the position of the first winch motor.

[0017] The side of the fixing rope connected to the main beam frame has a double-headed structure, which is fixedly connected to the top and bottom of the outer ring frame respectively. A fixing ring is provided at the intersection point that is inclined towards the center of the outer ring frame. The fixing ring is used to fix the double head into a single-headed structure.

[0018] The beneficial effects of adopting the above-mentioned improved scheme are as follows: By setting guide loops, it can be ensured that the fixing rope remains parallel to the top surface of the building when taut, thereby providing a uniform tension distribution, reducing structural instability caused by inconsistent rope angles, reducing mechanical problems caused by angle deviations, and improving the overall structural reliability. The double-ended structure of the fixing rope can provide more comprehensive support, enhance the vertical stability of the support frame, and prevent it from tilting or swaying. The double fixation of the fixing rope at the top and bottom helps to evenly distribute the load, reduce local stress concentration, and thus improve the overall stability of the structure.

[0019] Furthermore, the internal fixing connection assembly includes embedded rivets and internal tension members, and the external fixing connection assembly also includes rivets and external tension members;

[0020] The pre-embedded rivets are fixed on the building plane at the corresponding positions of the inner ring frame and the outer ring frame. The bottom of the rivets is a screw structure and the top is a flexible steel plate. After passing through the top of one side of the corresponding inner ring frame and outer ring frame, the rivets are fixed to the pre-embedded rivets by bolts. The flexible steel plate is made of shape memory metal.

[0021] The inner tension member includes an octagonal fixing member that is fixed to the center position of the inner ring frame by screws, and a compression spring connecting the inner ring frame and the octagonal fixing member.

[0022] The outer tension member includes a fixing nail and a tension steel core. The fixing nail is inclined and fixed on the plane of the building in the direction of the outer ring frame. A connecting lug is provided on the outside of the outer ring frame. The tension steel core is connected between the fixing nail and the connecting lug.

[0023] The inner tension member and the outer tension member work together to provide the main beam frame with a tensile force that acts both inward and outward to ensure the stability of the main beam frame.

[0024] The beneficial effects of adopting the above-mentioned improved scheme are as follows: By setting internal and external fixed connectors, a strong fixation can be provided, giving the connection parts high structural strength and stability. The flexible steel plate at the top can adapt to minor deformations, ensuring that the connection points can be stably fixed to the support frame, reducing loosening or instability caused by installation errors. Bolt fixing allows for quick and accurate installation of the connecting components, simplifying the installation process and improving efficiency. Bolted connections also allow for fine-tuning after installation to ensure precise mating and alignment of the components and the support frame.

[0025] By incorporating internal and external tension members, adaptive tension adjustment is provided. The internal tension member automatically adjusts its tension force according to load changes, thus maintaining the stability of the support frame and the overall structural integrity. The springs effectively absorb and reduce impacts caused by external load variations or vibrations, minimizing the impact of vibrations on the support frame and improving structural stability and comfort.

[0026] Furthermore, the cantilever beam extends integrally from the bottom of the inner ring frame and the outer ring frame outwards. The cantilever beam is a structure in which a straight plate and an arc plate are integrally connected. The arc plate is located on the outside of the straight plate and extends to the outside of the building. A sliding rail is provided on its surface for the lifting rope of the suspended platform to pass through. Reinforcing ribs are fixed on the side wall of the cantilever beam to support its stability. A triangular stability structure is fixed between the top of the cantilever beam and the upper structure of the outer ring frame to enhance the strength of the connection between the cantilever beam and the main beam frame.

[0027] A partition is provided on the upper surface of the cantilever beam. The height of the partition is higher than the height of the structure that controls the lifting and lowering of the suspended platform. The partition is provided with through holes for the lifting rope to pass through.

[0028] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting up a partition, it is possible to prevent the hoisting motor of the suspended platform from falling due to being suddenly pulled by the suspended platform, and the partition can provide a buffer for the falling of the hoisting motor of the suspended platform.

[0029] Furthermore, the horizontal adjustment assembly includes a reinforcing layer and rotating bolts. The reinforcing layer is fixed to the bottom two sides of the outer ring frame by the rotating bolts. The surface of the reinforcing layer is provided with multiple screw holes, each screw hole corresponding to one rotating bolt. A compression spring is provided between the reinforcing layer and the bottom of the outer ring frame. The tilt angle of the fixing plane of the outer ring frame is adjusted by the clamping force of the rotating bolts on the compression spring.

[0030] The horizontal adjustment component and the external fixing connector are arranged alternately.

[0031] The beneficial effects of adopting the above-mentioned improved scheme are as follows: By setting the rotating bolts, the thickness of the reinforcing layer can be adjusted to allow the support frame to precisely adapt to the slope of the building, ensuring that the support frame is level or consistent with the requirements of the building. The rotating bolts provide a convenient adjustment mechanism, allowing for quick and accurate fine-tuning of the support frame during installation and adjustment, thus simplifying the installation process.

[0032] Furthermore, the counterweight assembly includes pulleys, connecting ropes, a hoisting component, and a counterweight block. The pulleys are fixed to the top of the building plane, and there are two pulleys, respectively located on both sides of the suspended platform. One end of the connecting rope is fixed to the suspended platform, and the other end passes around the pulley and is fixed to the hoisting component. The counterweight block is manually placed on the hoisting component. The lever structure formed by the pulleys, the connecting ropes, the hoisting component, and the counterweight block is used to reduce the tensile force of the suspended platform lifting assembly on the suspended platform, thereby improving the stability of the suspended platform.

[0033] Furthermore, the braking assembly includes a second winch motor, a friction element, and a lifting rod. The second winch motor is fixed inside the inner ring frame and is connected to the suspended basket via the friction element. The lifting rod is positioned between the second winch motor and the suspended basket. A brake element matching the friction element is fixed to the top of the lifting rod. The friction force generated when the friction element contacts the brake element causes the friction element to exert an upward force on the suspended basket, thus performing emergency braking on the suspended basket.

[0034] Furthermore, the lifting rod comprises multiple members, and the tilt angle of its top braking member is the same as the tilt angle of the friction member at the corresponding position.

[0035] Compared with existing technologies, the beneficial effects of the suspended platform stability assistance system provided by this invention are as follows: By setting up a support frame, it can be fixed to the top of the building, providing stable support for the suspended platform and preventing it from swaying or tilting during use, thereby improving operational safety; the support frame can evenly distribute the load of the suspended platform, reducing local pressure on the building structure and lowering the risk of damage to the building; the stable support frame allows the suspended platform to work steadily at high altitudes, improving the accuracy and efficiency of worker operations and shortening construction time. By setting up a horizontal adjustment component, the support frame can be kept stable, thereby avoiding tilting or instability caused by slope, ensuring the stability of the suspended platform during high-altitude operations; by eliminating the influence of slope on the support frame, the safety risks caused by instability are reduced; at the same time, it can adapt to building surfaces with different slopes, expanding the application range and flexibility of the support frame. By setting up a counterweight component, the suspension platform's descent height and load weight can be balanced, preventing instability or swaying during operation, thereby improving operational safety. The counterweight component can adjust the counterweight according to the weight loaded on the suspended platform, adapting to different load conditions, thus enabling the suspended platform to operate stably. By installing braking components, the rapid descent of the suspended platform can be prevented, thus preventing accidental falls due to slippage or other malfunctions, thereby significantly improving the safety of workers and equipment; and effectively avoiding the potential risks caused by rapid falls.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0045] like Figure 1-5 The diagram illustrates an embodiment of a suspended platform stability assistance system provided by the present invention. This embodiment includes a support frame 10, a horizontal adjustment component 20, a counterweight component 30, and a braking component 40. The bottom of the support frame 10 is fixed to any plane on the top of the building, providing stability support for the suspended platform. The horizontal adjustment component 20 is provided at the bottom of the support frame 10, used to adjust the tilt angle of the support frame 10. One end of the counterweight component 30 is fixedly connected to the suspended platform, forming a lever structure between them, used to balance the descent height and the loaded weight of the suspended platform to ensure its stability during operation. One end of the braking component 40 is fixedly connected to the support frame 10, and the other end is connected to the suspended platform, used to apply emergency braking to the suspended platform in case of abnormal operation, ensuring its safety during operation.

[0046] The structure of the suspended platform is referenced in Chinese Patent No. CN202310238101.1 (Publication No.: CN115929008B): A Suspended Platform for Urban Construction.

[0047] In the above technical solution, the support frame 10 includes a main beam frame 11 and a cantilever beam 12. The main beam frame 11 is fixed at the top of the building, and the cantilever beam 12 is fixedly connected to the main beam frame 11 to extend outward to the outside of the building so that the width of the suspended basket can be adjusted from the building.

[0048] The main beam frame 11 includes an inner ring frame 111, which is fixed to the building's plan position by an inner fixing connection assembly. The inner ring frame 111 has an octagonal structure. An outer ring frame 112 is provided on the outside of the inner ring frame 111, and the outer ring frame 112 is concentrically corresponding to the inner ring frame 111. A horizontal adjustment assembly 20 is fixed to the bottom of the outer ring frame 112 to adjust the tilt angle of the plane formed by the inner ring frame 111 and the outer ring frame 112. The outer ring frame 112 is fixed to the top of the building by an external fixing connection assembly.

[0049] The inner ring frame 111 and the outer ring frame 112 are fixedly connected by a horizontal bar 113. The horizontal bar 113 includes three layers: upper, middle and lower, which successively enhance the connection strength between the inner ring frame 111 and the outer ring frame 112. Multiple diagonal bars 114 are fixed between the three layers of horizontal bars 113. The connection angles between the diagonal bars 114 and the inner ring frame 111, the outer ring frame 112 and the horizontal bar 113 are all 45°. They form triangular structures between adjacent inner ring frames 111, outer ring frames 112 and horizontal bars 113 to distribute the force and ensure the structural stability of the support frame 10.

[0050] Furthermore, in the above technical solution, both the inner ring frame 111 and the outer ring frame 112 are structures composed of square frames. Vertical rods and diagonal rods are fixed inside the square frames to enhance the stability of the inner ring frame 111 and the outer ring frame 112.

[0051] The inner ring frame 111, outer ring frame 112, horizontal bar 113 and diagonal bar 114 are all made of aluminum alloy, and adjacent structures are fixedly connected by reinforcing bolts.

[0052] Furthermore, in the above technical solution, a tension member 115 is fixed on the side of the main beam frame 11 that is close to the interior of the building and away from the cantilever beam 12. The tension member 115 includes a first winch motor 1151, a guide ring 1152, and a fixing rope 1153. The first winch motor 1151 is fixed inside the building. The guide ring 1152 is disposed between the first winch motor 1151 and the main beam frame 11. One end of the fixing rope 1153 is fixed to the main beam frame 11, and the other end passes through the guide ring 1152 and is wound around the first winch motor 1151. The first winch motor 1151 is used to give the main beam frame 11 a force toward the interior of the building by stretching the fixing rope 1153 to ensure the stability of the cantilever beam 12.

[0053] The guide ring 1152 is fixed to the surface of the building by a bracket, and its height is the same as that of the first winch motor 1151, so that the fixing rope 1153 is parallel to the top plane of the building between the guide ring 1152 and the first winch motor 1151; the inside of the guide ring 1152 is inclined, and its inclination angle is the inclination angle between the center position of the main beam frame 11 and the position of the first winch motor 1151.

[0054] The side of the fixing rope 1153 connected to the main beam frame 11 is a double-headed structure, which is fixedly connected to the top and bottom of the outer ring frame 112 respectively. A fixing ring is provided at the intersection of the rope 1153 and the outer ring frame 112, which is inclined towards the center of the outer ring frame 112. The fixing ring is used to fix the double head into a single-headed structure.

[0055] Furthermore, in the above technical solution, the internal fixing connection assembly includes embedded rivets and internal tension members, and the external fixing connection assembly also includes rivets and external tension members.

[0056] The pre-embedded rivets are fixed on the building plane at the corresponding positions of the inner ring frame 111 and the outer ring frame 112. The bottom of the rivets is a screw structure and the top is a flexible steel plate. After passing through the top of one side of the corresponding inner ring frame 111 and outer ring frame 112, the rivets are fixed to the pre-embedded rivets by bolts. The flexible steel plate is made of memory metal.

[0057] The inner tension member includes an octagonal fastener fixed to the center of the inner ring frame 111 by screws and a compression spring connected between the inner ring frame 111 and the octagonal fastener.

[0058] The outer tension member includes a fixing nail and a tension steel core. The fixing nail is inclined and fixed on the plane of the building in the direction of the outer ring frame 112. The outer ring frame 112 is provided with a connecting ear on the outside. The tension steel core is connected between the fixing nail and the connecting ear.

[0059] The combined action of the inner and outer tension members provides the main beam frame 11 with tensile forces acting inward and outward to ensure the stability of the main beam frame 11.

[0060] Furthermore, in the above technical solution, the bottom of the inner ring frame 111 and the outer ring frame 112 extends integrally from the inside to the outside to form a cantilever beam 12. The cantilever beam 12 is a structure in which a straight plate and an arc plate are integrally connected. The arc plate is set on the outside of the straight plate and extends to the outside of the building. A sliding rail is provided on its surface for passing through the lifting rope of the suspended platform. Reinforcing ribs are fixed on the side wall of the cantilever beam 12 to support the stability of the cantilever beam 12. A triangular stability structure is fixed between the top of the cantilever beam 12 and the upper structure of the outer ring frame 112 to enhance the strength of the connection between the cantilever beam 12 and the main beam frame 11.

[0061] A partition is provided on the upper surface of the cantilever beam 12. The height of the partition is higher than the height of the structure that controls the lifting of the suspended platform. The partition has through holes for the lifting ropes to pass through.

[0062] Furthermore, in the above technical solution, the horizontal adjustment component 20 includes a reinforcing layer 21 and a rotating bolt 22. The reinforcing layer 21 is fixed to the bottom sides of the outer ring frame 112 by the rotating bolt 22. The surface of the reinforcing layer 21 is provided with a plurality of screw holes, each screw hole corresponding to a rotating bolt 22. A compression spring is provided between the reinforcing layer 21 and the bottom of the outer ring frame 112. The tilt angle of the fixed plane of the outer ring frame 112 is adjusted by the clamping force of the rotating bolt 22 on the compression spring.

[0063] The horizontal adjustment component 20 is staggered with the external fixed connector.

[0064] Furthermore, in the above technical solution, the counterweight assembly 30 includes a pulley 31, a connecting rope 32, a hoisting component 33, and a counterweight block 34. The pulley 31 is fixed to the top of the building plane, including two pulleys, which are respectively set on both sides of the suspended platform. One end of the connecting rope 32 is fixed to the suspended platform, and the other end passes around the pulley 31 and is fixed to the hoisting component 33. The counterweight block 34 is manually placed on the hoisting component 33. The lever structure composed of the pulley 31, the connecting rope 32, the hoisting component 33, and the counterweight block 34 is used to reduce the tensile force of the suspended platform lifting assembly on the suspended platform to improve the stability of the suspended platform.

[0065] Furthermore, in the above technical solution, the braking assembly 40 includes a second winch motor 41, a friction element 42, and a lifting rod 43. The second winch motor 41 is fixed inside the inner ring frame 111 and is connected to the suspended basket through the friction element 42. The lifting rod 43 is positioned between the second winch motor 41 and the suspended basket. A brake element matching the friction element 42 is fixed to the top of the lifting rod 43. The friction force generated when the friction element 42 contacts the brake element causes the friction element 42 to exert an upward force on the suspended basket, thus performing emergency braking on the suspended basket.

[0066] The top brake is made of rubber with a rough textured surface. The lifting rod 43 is a cuboid structure made of steel with a cross-section of 40*90mm.

[0067] Furthermore, in the above technical solution, the lifting rod 43 includes multiple rods, and the tilt angle of its top braking component is the same as the tilt angle of the corresponding friction component 42.

[0068] Adjusting the rotating bolts 22 at different positions changes the height of the reinforcing layer 21, thereby causing the inner ring frame 111 and outer ring frame 112 at corresponding positions to change height to adapt to the sloping roof surface, ensuring the stability of the octagonal support frame 10. During operation, the hoisting motor pulls the basket upwards, and the lifting rope connected to the basket slides at the arc plate of the cantilever beam 12. Simultaneously, because the connecting rope 32 is connected to the basket, the lifting component 33 descends as the basket rises. A suitable counterweight 34 is selected based on the weight of the basket. According to the lever balance formula F1L1=F2L2, the product of the basket's weight and the length from the basket to the pulley 31 is equal to the product of the sum of the weights of the lifting component 33 and the counterweight 34 and the distance between the lifting component 33 and the pulley 31. Because the friction component 42 is connected to the basket, as the basket rises, the friction component 42 rubs against the top brake, limiting the basket's lifting speed. When the suspension basket slips, the friction of the top braking component can prevent the suspension basket from falling rapidly.

[0069] Example:

[0070] The support frame and main beam frame are made of aluminum alloy. The inner ring frame is octagonal with a side length of 3 meters. The outer ring frame is 0.5 meters away from the edge of the inner ring frame. The horizontal bars are in three layers, each layer is 0.1 meters wide, with a 0.5-meter distance between the upper and lower layers and a 0.3-meter distance between the middle layers.

[0071] The cantilever beams are made of aluminum alloy and steel, with straight plates 1 meter wide, curved plates extending 0.8 meters to the exterior of the building, and sliding rails 0.2 meters wide.

[0072] The tensioning components include a first winch motor with a power of 2kW; a wire ring with an inclination angle of 10°; and a fixing rope with a length of 20 meters.

[0073] The reinforcing layer is 0.05 meters thick and has a bottom width of 2 meters.

[0074] Two pulleys, each 0.3 meters in diameter. A connecting rope, 0.02 meters in diameter and 20 meters in length. Lifting components: rated load 500 kg. Counterweights (34): each weighing 200 kg, total weight 600 kg.

[0075] Second hoist motor: power is 1.5kW. Friction coefficient of friction is 0.8. Lifting rod: 3 rods, each 2 meters long, with a brake fixed at the top, and the tilt angle is the same as that of the friction rod.

[0076] The suspended platform has a maximum load capacity of 800 kg and a weight of 200 kg. The working height is adjustable up to 50 meters. Through the design of the counterweight components and support frame, the stability of the suspended platform under maximum load is ensured to be no less than 90%.

[0077] Specifically, the principle of this invention is as follows: adjusting the rotating bolts 22 at different positions changes the height of the reinforcing layer 21, thereby causing the inner ring frame 111 and outer ring frame 112 at corresponding positions to change height to adapt to the sloping roof surface, thus keeping the octagonal support frame 10 stable. During operation, the hoisting motor pulls the basket upwards, and the lifting rope connected to the basket slides at the arc plate of the cantilever beam 12. Simultaneously, because the connecting rope 32 is connected to the basket, the lifting component 33 descends as the basket rises. A suitable counterweight 34 is selected based on the weight of the basket. According to the lever balance formula F1L1=F2L2, the product of the basket's weight and the length from the basket to the pulley 31 is equal to the product of the sum of the weights of the lifting component 33 and the counterweight 34 and the distance between the lifting component 33 and the pulley 31. Because the friction component 42 is connected to the basket, as the basket rises, the friction component 42 rubs against the top brake, limiting the basket's lifting speed.
