Abstract
Description
Technical Field
[0001] This invention belongs to the field of construction machinery technology, specifically relating to an adjustable and reinforced suspended platform support foot device and adjustment method. Background Technology
[0002] In high-altitude operations in construction projects, electric suspended platforms are core equipment for exterior wall construction, painting, maintenance, and renovation. Their ground support and leveling directly affect construction safety and work efficiency. Traditional suspended platforms generally use fixed rigid structures for their support legs, which are not height-adjustable. When encountering complex construction ground with unevenness, varying slopes, or local settlement, it is necessary to manually place auxiliary components such as wooden blocks, steel plates, and mortar blocks to barely level the surface. This is not only cumbersome and time-consuming, but also prone to problems such as slippage of the support blocks, inadequate support, and local suspension, causing the suspended platform to tilt and sway after landing, posing serious safety hazards for high-altitude operations.
[0003] With technological advancements, a small number of adjustable suspended platform support legs have appeared on the market. However, these devices are mostly single-stage manual screw adjustments or single-cylinder lifting, only capable of single-stroke adjustment. They cannot simultaneously meet the dual requirements of rapid, large-stroke adjustment and high-precision micro-leveling. Their adjustment speed is slow, and their positioning accuracy is poor, making it difficult to meet high-standard construction requirements. More significantly, existing devices all adopt a working mode of adjusting only after the platform touches the ground. This means that ground height differences cannot be predicted and compensated for in advance during the stage when the suspended platform is about to touch the ground, leading to impact and swaying at the moment of landing, resulting in poor stability. Summary of the Invention
[0004] In view of this, the purpose of the present invention is to provide an adjustable and reinforced suspended platform support foot device and adjustment method to solve the problem that the current suspended platform cannot compensate for the ground height difference in advance before it descends to the ground, resulting in an excessive tilt angle when the suspended platform lands, which affects the safety of the workers.
[0005] To achieve the above objectives, the present invention provides the following technical solution: An adjustable reinforced suspended platform support foot device includes a suspended platform body and a reinforced support truss disposed on the lower surface of the suspended platform body. Vertically arranged adjustable support feet are provided around the reinforced support truss. Each adjustable support foot includes a support shell, a telescopic shell slidingly passing through the lower end of the support shell, and a first drive motor that drives the telescopic shell to move. The telescopic shell and the support shell are coaxially nested. The first drive motor is vertically fixedly installed inside the support shell, and its output end is poweredly connected to a transmission screw. The transmission screw is vertically rotatable within the support shell, and its end away from the first drive motor passes through the telescopic shell and is threadedly connected to it. Horizontally arranged winding motors are provided at the four corners of the upper surface of the suspended platform body. Steel cables are fixedly connected to the output ends of each winding motor, and the free ends of each steel cable are connected to a suspension lifting mechanism for raising and lowering the suspended platform body. Each adjustable support foot corresponds one-to-one with an adjacent winding motor and steel cable and cooperates with it.
[0006] Furthermore, a movable housing is elastically slidably inserted through the end of the telescopic housing away from the supporting housing. The movable housing and the telescopic housing are coaxially nested. The telescopic housing is provided with a fine-tuning component for driving the movement of the movable housing. The fine-tuning component includes a cam rotatably disposed in the telescopic housing and a second drive motor that drives the cam to rotate. The second drive motor is vertically fixedly installed in the movable housing, and the output end of the second drive motor is connected to a worm gear. A worm wheel that meshes with the worm gear is coaxially connected at the rotation center of the cam. The upper surface of the movable housing abuts against the peripheral surface of the cam.
[0007] Furthermore, the transmission screw is provided in two parts, and the two transmission screws are symmetrically arranged about the horizontal axis of the support housing. The first drive motor rotates synchronously with each transmission screw, and the rotation center of the cam is located on the vertical center line of the telescopic housing.
[0008] Furthermore, the upper surface of the movable housing is provided with a groove that matches the peripheral surface of the cam, and a roller is rotatably connected in the groove. The roller is located directly below the cam, and the roller abuts against the peripheral surface of the cam.
[0009] Furthermore, the end of the movable housing away from the telescopic housing is hinged to a support base via a ball joint.
[0010] Furthermore, a dual-axis tilt sensor is provided at the center of the lower surface of the main body of the suspended basket, a pressure sensor and a distance sensor are provided on the lower surface of each of the support bases, and a tension sensor is provided at the connection between each of the winding motors and the steel cable. The distance sensor, pressure sensor, tension sensor, winding motor, first drive motor, second drive motor and dual-axis tilt sensor are all electrically connected to a central controller.
[0011] An adjustable and reinforced suspended platform adjustment method, applied to the aforementioned adjustable and reinforced suspended platform support foot device, includes the following implementation steps; S1. During the descent of the suspended platform, each distance sensor detects the distance between the support base and the ground in real time and transmits the distance signal to the central controller. S2. When the distance sensor detects that the support base is close to the ground, the central controller controls the first drive motor of each adjustable support foot to start, and drives the telescopic shell to extend through the transmission screw to complete the pre-leveling before landing and compensate for the height difference of the four corners of the ground. S3. The main body of the suspended platform continues to descend until the pressure sensor at the bottom of the support base detects the ground contact signal and uploads it to the central controller. The central controller collects the levelness signal of the main body of the suspended platform in real time through the dual-axis tilt sensor. S4. When the central controller determines that the main body of the suspended platform needs to be leveled again, it first controls the winding motor of the corresponding corner to wind the steel cable in the forward direction until the pressure sensor detects that the support base of the corner is completely unloaded and stops the winding motor. S5. The central controller starts the first drive motor and the second drive motor respectively according to the tilt angle. The first drive motor controls the transmission screw to achieve rapid coarse adjustment over a wide range of strokes. The second drive motor drives the cam to rotate through the worm gear and worm wheel, driving the movable shell to perform small-stroke high-precision telescopic adjustment. After the compensation distance is in place, the controller controls the winding motor to release the steel cable in reverse, so that the movable shell can be pressured again. S6. Perform steps S4 to S5 sequentially on each corner until the dual-axis tilt sensor detects that the main body of the suspended platform has reached the set level. The central controller then locks each mechanism, and the leveling is completed.
[0012] The beneficial effects of this invention are as follows: 1. This invention can detect and predict ground height differences and unevenness in advance during the descent of the suspended platform. When the support feet are about to touch the ground, the pre-compensation adjustment is initiated. The large-stroke coarse adjustment mechanism quickly compensates for the height difference at the four corners, fundamentally preventing tilting, shaking, slippage and impact when the suspended platform lands. This achieves a stable ground contact and quick positioning of the suspended platform, eliminating the tedious process of manually setting up pads and making repeated adjustments. It significantly improves the efficiency of the suspended platform's landing and initial support stability, and is more adaptable to the complex and ever-changing ground conditions at construction sites. 2. This invention adopts a closed-loop control mode that combines the coordinated unloading of the winding motor with coarse and fine two-stage adjustment. The winding motor can effectively unload the load at the bottom of each adjustable support foot while allowing each adjustable support foot to automatically and quickly adjust its extension and retraction according to the tilt angle. Large angle deviations are quickly coarsely adjusted using a screw mechanism, while small angle deviations are finely adjusted using a cam mechanism. Combined with the worm gear self-locking and rolling friction transmission, the adjustment process is ensured to be smooth and without jamming, with uniform force and no overload. Ultimately, it achieves high-precision horizontal positioning of the suspended platform, greatly improving the leveling accuracy, structural reliability, and safety of high-altitude operations.

[0015] like Figures 1-6 As shown, An adjustable reinforced suspended platform support foot device includes a suspended platform body 1 and a reinforced support truss 2 disposed on the lower surface of the suspended platform body 1. The reinforced support truss 2 is detachably connected to the suspended platform body 1 by bolts. Vertically arranged adjustable support feet 3 are provided around the reinforced support truss 2. Each adjustable support foot 3 includes a support housing 301, a telescopic housing 302 slidingly passing through the lower end of the support housing 301, and a first drive motor 303 driving the telescopic housing 302. The support housing 301 is welded and fixed to the support truss. The telescopic housing 302 is coaxially nested with the support housing 301. The first drive motor 303 is vertically fixedly installed inside the support housing 301. The vertical centerline of the housing 301 is coaxially arranged, and the output end of the first drive motor 303 is poweredly connected to the transmission screw 304. The transmission screw 304 is vertically rotatably arranged inside the supporting housing 301, and the end of the transmission screw 304 away from the first drive motor 303 passes through the telescopic housing 302 and is threadedly connected to it. At the four corners of the upper surface of the suspended basket body 1, there are horizontally arranged winding motors 4. The output end of each winding motor 4 is fixedly connected to a steel cable 5, and the free end of each steel cable 5 is connected to a suspension lifting mechanism for lifting the suspended basket body 1. Each adjustable support foot 3 corresponds one-to-one with the adjacent winding motor 4 and steel cable 5 and cooperates with each other. The suspension lifting mechanism is installed on the top of the building and is not shown in the figure.
[0016] As shown in the figure, when the main body 1 of the suspended platform is working at height, the winding motors 4 do not participate in the work, but only participate in the coordinated work during the leveling. The lifting and lowering of the main body 1 of the suspended platform is mainly controlled by the suspension hoist. When the main body 1 of the suspended platform is about to be lowered to the ground by the suspension hoist, the first drive motors 303 are started. The output end of the first drive motor 303 drives the transmission screw 304 to rotate. The transmission screw 304 then drives the telescopic housing 302 to move through the thread. One end of the telescopic housing 302 moves along the axis of the transmission screw 304 and extends out of the support housing 301. By controlling the length of each telescopic housing 302 extending out of the support housing 301, the main body 1 of the suspended platform is indirectly kept horizontal after contacting the ground, thus achieving pre-compensation for the main body 1 of the suspended platform before contacting the ground. When the telescopic housings 302 at the bottom of the suspended platform body 1 contact the ground, the ground at the construction site may not have been properly hardened, causing a depression after the telescopic housings 302 come into contact with the ground. In this case, the telescopic housings 302 need to be adjusted again to compensate for the depression. For example, when the upper left telescopic housing 302 contacts the ground and causes a depression, the suspended platform body 1 will tilt in that direction. At this point, the winding motor 4 corresponding to the upper left telescopic housing 302 starts winding the steel cable 5 connected to it, causing the tilted position of the upper left corner of the suspended platform body 1 to gradually rise until the suspended platform body 1 is back to a horizontal position. The winding motor 4 then stops working, and the telescopic housing 302 at this point... 2. With the bottom suspended and no longer bearing weight, the overall weight of the suspended platform body 1 and the reinforcing support truss 2 is shared by the winding motor 4 in the upper left corner and the other support shells 301. Subsequently, the first drive motor 303 corresponding to the telescopic shell 302 in the upper left corner is controlled again, causing the telescopic shell 302 to move a distance away from the support shell 301, continuing to compensate for the height error at the ground depression until the bottom of the telescopic shell 302 touches the ground again and bears force, keeping the suspended platform body 1 in a horizontal state. The winding motor 4 in the upper left corner can release the wire rope and no longer bear force. The overall weight of the suspended platform body 1 and the processing support truss is borne by the four adjustable support feet 3. Similarly, when there is a depression in the road surface at the bottom of any or several telescopic shells 302, the telescopic length of each telescopic shell 302 can be quickly adjusted by starting the corresponding winding motor 4 to ensure the horizontality of the suspended platform body 1 when placed on the ground.
[0017] This device works in coordination with the adjustable support feet 3 and the cable 5 winding mechanism. It can adaptively adjust the length of the telescopic support in advance during the landing stage of the suspended platform body 1, effectively achieving pre-height compensation for the landing posture and ensuring that the suspended platform body 1 remains stable and level after contacting the ground. For construction site conditions where the ground is soft and prone to settlement, or has local depressions and unevenness, it can quickly balance the tilt posture of the suspended platform body 1 by linking the corresponding winding motor 4, flexibly adjust the extension and retraction stroke of the support feet to compensate for the ground settlement difference, and distribute the overall load by bearing force at multiple points simultaneously, greatly improving the stability of the suspended platform body 1 when it is placed on the ground.
[0018] In this embodiment, a movable housing 6 is elastically slidably inserted through one end of the telescopic housing 302 away from the supporting housing 301. The movable housing 6 and the telescopic housing 302 are coaxially nested. The telescopic housing 302 is provided with a fine-tuning component for driving the movement of the movable housing 6. The fine-tuning component includes a cam 7 rotatably disposed in the telescopic housing 302 and a second drive motor 8 that drives the cam 7 to rotate. The second drive motor 8 is vertically fixedly installed in the movable housing 6, and the output end of the second drive motor 8 is connected to a worm gear 9. A worm wheel 10 that meshes with the worm gear 9 is coaxially connected at the rotation center of the cam 7. The worm wheel 10 and the cam 7 are coaxially spaced apart. The upper surface of the movable housing 6 abuts against the peripheral surface of the cam 7.
[0019] As shown in the figure, when fine-tuning of the telescopic height of the adjustable support leg 3 is required, the second drive motor 8 is activated. The second drive motor 8 drives the worm gear 9 to rotate, and the worm gear 9 in turn drives the cam 7 to rotate. The cam 7 abuts against the upper surface of the movable housing 6 through its peripheral surface, causing the movable housing 6 to move away from the telescopic housing 302. Through the cooperation between the cam 7 and the movable housing 6, stepless adjustment of the telescopic distance of the movable housing 6 is achieved, thereby indirectly achieving fine-tuning of the height of the suspended platform body 1 with a small stroke. Combined with the large stroke rapid coarse adjustment between the transmission screw 304 and the telescopic housing 302, the efficiency and accuracy of the leveling process of the suspended platform body 1 can be effectively improved, thereby ultimately ensuring the levelness of the suspended platform body 1.
[0020] By adding a worm gear 10 and worm 9 transmission in conjunction with a cam 7 push-type fine-tuning component, the support height can be rapidly and continuously adjusted steplessly by extending the support leg length, building upon the existing large-stroke coarse adjustment of the transmission screw 304. The coarse and fine adjustments work in tandem, with clear division of labor. This allows for rapid and wide-range adaptation to uneven ground with significant elevation differences, while also enabling high-precision, small-distance attitude correction of the overall posture of the suspended platform 1. This significantly improves the overall leveling response speed and accuracy of the suspended platform 1. The worm gear 10 and worm 9 meshing transmission has excellent self-locking performance, ensuring a stable support position after adjustment and preventing displacement or loosening. The elastic nested movable shell 6 provides better force buffering, further optimizing the landing force state of the suspended platform 1, effectively avoiding localized force concentration problems, and comprehensively ensuring the stable and level parking of the suspended platform 1. This significantly improves the safety, adaptability to working conditions, and overall operational stability of the high-altitude construction suspended platform 1. In this embodiment, two transmission screws 304 are provided, and the two transmission screws 304 are symmetrically arranged about the horizontal axis of the support housing 301. The output end of the first drive motor 303 is connected to a drive gear 11. One end of each transmission screw 304 is coaxially fixed with a transmission gear 12 that meshes with the drive gear 11. The first drive motor 303 rotates synchronously with each transmission screw 304 through the meshing of the drive gear 11 and the transmission gear 12. The rotation center of the cam 7 is located on the vertical center line of the telescopic housing 302.
[0021] As shown in the figure, the two transmission screws 304 effectively ensure the stability of the telescopic housing 302 during movement, making the force on the telescopic housing 302 more balanced during telescopic sliding. This effectively prevents the offset, jamming, and shaking caused by unilateral force, and significantly improves the overall stability and structural rigidity of the support leg's telescopic movement. The symmetrical layout of the dual transmission screws 304 optimizes the internal space layout of the support housing 301, avoids interference in component installation, and provides sufficient assembly and movement space for the fine-tuning components such as the second drive motor 8, cam 7, worm gear 10, and worm 9 inside the telescopic housing 302. The structure is compact and reasonable.
[0022] In this embodiment, the upper surface of the movable housing 6 is provided with a groove 13 that matches the peripheral surface of the cam 7, and a roller 14 is rotatably connected in the groove 13. The roller 14 is located directly below the cam 7, and the roller 14 abuts against the peripheral surface of the cam 7. The surface where the roller 14 contacts the cam 7 is a continuous smooth surface.
[0023] As shown in the figure, the hard sliding friction between cam 7 and movable housing 6 is transformed into rolling friction between cam 7 and roller 14. This significantly reduces the frictional resistance and mechanical wear when cam 7 rotates, reduces the energy consumption and transmission noise of the fine-tuning components, and makes the small-stroke high-precision adjustment process driven by cam 7 smoother and more sensitive. At the same time, it avoids the problems of component jamming, sticking, and structural wear and deformation caused by long-term hard contact, effectively extends the service life of precision adjustment components such as cam 7 and movable housing 6, improves the smoothness and adjustment accuracy of the support leg height fine-tuning action, ensures the stability and reliability of the attitude fine-tuning process of the suspended basket body 1, and further optimizes the overall device's operational durability and operational stability.
[0024] In this embodiment, the end of the movable shell 6 away from the telescopic shell 302 is connected to a support base 15 via a ball joint hinge. The support base 15 has an adaptive adjustment capability with free deflection at multiple angles, and can autonomously conform to the complex ground with unevenness and varying slopes at the construction site, effectively eliminating the force deviation caused by single-point hard contact; the ball joint hinge structure can flexibly adapt to the ground tilt angle, increase the contact area between the support base 15 and the ground, disperse local concentrated loads, and avoid single-point overload, slippage, or overturning of the support leg.
[0025] In this embodiment, a dual-axis tilt sensor is provided at the center of the lower surface of the suspended basket body 1, and a pressure sensor and a distance sensor are provided on the lower surface of each of the support bases 15. A tension sensor is provided at the connection between each of the winding motors 4 and the steel cable 5. The distance sensor, pressure sensor, tension sensor, winding motor 4, first drive motor 303, second drive motor 8 and dual-axis tilt sensor are all electrically connected to a central controller.
[0026] An adjustable and reinforced suspended platform adjustment method, applied to the aforementioned adjustable and reinforced suspended platform support foot device, includes the following implementation steps; S1. During the descent of the main body 1 of the suspended platform, the distance sensors at each support base 15 detect the distance between the support base 15 and the ground in real time and transmit the distance signal to the central controller in real time. S2. When the distance sensor detects that the support base 15 is close to the ground, the central controller controls the first drive motor 303 of each adjustable support foot 3 to start synchronously. The telescopic shell 302 is driven to extend downward through the double transmission screw 304 to pre-compensate and level the ground height difference at the four corners before landing, so that the main body of the suspended basket 1 maintains a near-horizontal posture when it is about to touch the ground. S3. The main body of the suspended platform 1 continues to descend slowly until the pressure sensors at the bottom of each support base 15 detect a stable ground contact signal and upload it to the central controller. The central controller collects and judges the current levelness of the main body of the suspended platform 1 in real time through the dual-axis tilt sensor at the center of the main body of the suspended platform 1. S4. When the central controller determines that the main body 1 of the suspended platform needs to be leveled again due to ground subsidence or depression according to the preset program, it first locks the corner with the largest tilt angle and controls the winding motor 4 corresponding to the corner to wind the steel cable 5 in the forward direction until the corresponding pressure sensor detects that the support base 15 is completely unloaded and the support is suspended. The winding motor 4 stops operating and maintains the current state. S5. The central controller adjusts the tilt in stages according to the size of the tilt: when the tilt is large, the first drive motor 303 is started first to complete the large stroke and rapid coarse adjustment; when the tilt is small, the second drive motor 8 is started directly; the second drive motor 8 drives the cam 7 to rotate through the worm 9 and worm wheel 10, and the cam 7 pushes the movable housing 6 to achieve small stroke and high-precision telescopic adjustment; after the height compensation is in place, the central controller controls the winding motor 4 to slowly release the steel cable 5 in the reverse direction until the pressure sensor detects that the support base 15 is stable and bearing pressure again. S6. Repeat steps S4 to S5 for each corner in sequence according to the degree of tilt, until the dual-axis tilt sensor detects that the level of the main body 1 of the suspended basket reaches the preset threshold. The central controller then controls the first drive motor 303, the second drive motor 8, and the winding motor 4 to lock, and the leveling is completed.
[0027] When the tilt angle is greater than 1°, it is determined to be a large angle deviation. The first drive motor 303 is started to perform a large stroke rapid coarse adjustment. The effective stroke of the coarse adjustment is 0 to 300 mm, and the adjustment accuracy is ±1 mm. When the tilt angle is ≤1°, it is determined to be a small angle deviation. The second drive motor 8 is started to perform a small stroke high-precision fine adjustment. The effective fine adjustment stroke is 0~25mm and the adjustment accuracy is ≤0.05mm. The leveling process continues until the dual-axis tilt sensor detects that the tilt angle of the main body 1 of the suspended platform is ≤0.1°, reaching the set level. The central controller then locks all mechanisms, and the leveling is completed.
[0028] Of course, parameters such as the preset threshold for tilt angle, adjustable screw, and cam 7 can be reasonably modified according to the actual size of the suspended basket body 1 to ensure its rationality in actual use.

S5. The central controller starts the first drive motor (303) and the second drive motor (8) respectively according to the tilt angle. The first drive motor (303) controls the transmission screw (304) to achieve rapid coarse adjustment over a wide range of strokes. The second drive motor (8) drives the cam (7) to rotate through the worm (9) and worm wheel (10), driving the movable housing (6) to perform small-stroke high-precision telescopic adjustment. After the compensation distance is in place, the winding motor (4) is controlled to release the steel cable (5) in the reverse direction, so that the movable housing (6) can bear pressure again. S6. Perform steps S4 to S5 sequentially on each corner until the dual-axis tilt sensor detects that the main body (1) of the suspended basket has reached the set level. The central controller then controls each mechanism to lock, and the leveling is completed.
