Description

Technical Field

[0001] This application relates to the field of construction suspended platform equipment technology, and in particular to a suspended platform for high-rise building construction. Background Technology

[0002] With the continuous advancement of urbanization in my country, high-rise and super high-rise buildings are springing up like mushrooms after rain. In the construction, decoration, maintenance and other operations of high-rise buildings, suspended platforms, as an important type of high-altitude work equipment, have been widely used in various construction projects due to their advantages such as simple structure, convenient installation and disassembly, flexible operation and relatively low cost.

[0003] In the construction of high-rise buildings, situations often require repeated work on the same area, such as multiple coats of exterior wall paint, layered insulation layer construction, and fine adjustments for curtain wall installation. In these situations, workers need to frequently perform small-scale adjustments in the vertical direction. However, the lifting and lowering operation of traditional suspended platforms is relatively complex, requiring workers to stop their current work, operate the hoist control buttons, wait for the platform to slowly rise and fall to the target position, and then resume work. This process is not only inefficient but also disrupts the worker's work rhythm. To save time and improve efficiency, some workers resort to unsafe practices: directly climbing the safety railings of the suspended platform and stretching their bodies to reach the work point, which poses serious safety hazards.

[0004] Although modern suspended platform systems are equipped with comprehensive safety protection devices, including safety locks, safety ropes, and shock absorbers, suspended platform falls can still occur in extreme situations. When a suspended platform suddenly falls, workers will instinctively grab onto the platform's railings or other fixed components to stabilize themselves. When the safety rope begins to taut and pull upwards on the worker's body, it can easily lead to severe strain injuries. Summary of the Invention

[0005] This application proposes a suspended platform for high-rise building construction. By setting up a laterally movable gantry and independently liftable pedal assembly, the working range of workers is expanded and climbing of guardrails is avoided. At the same time, the detachable connection structure between the handrail and the pedal assembly is adopted to automatically sever the mechanical connection between the worker and the falling platform when the platform falls, effectively avoiding two major safety hazards in high-altitude operations.

[0006] To achieve the above objectives, this application adopts the following technical solution: a suspended platform for high-rise building construction, comprising a frame, a traction rope assembly, and a suspended platform. The frame is connected to the suspended platform via the traction rope assembly to achieve lifting and lowering. The suspended platform is equipped with a horizontally movable gantry, which is connected to a vertical guide rail. A footboard assembly is slidably connected to the guide rail. The footboard assembly is movably connected to a handrail, which includes an upright and a guardrail. A height difference of not less than 0.8 meters is maintained between the guardrail and the footboard assembly to form effective protection. The footboard assembly is equipped with a footboard for workers to stand on and can be lifted and lowered independently of the suspended platform to expand the working area and prevent workers from climbing the guardrail. The handrail and the footboard assembly adopt a detachable connection structure. When the suspended platform falls, the handrail can automatically detach from the footboard assembly to avoid workers being injured by instinctive gripping. Furthermore, the movable gantry includes a drive wheel, which rotates to drive the gantry to move laterally. The drive wheel is connected to a drive component, which includes a worm gear. The worm gear is movably connected to a movable plate via a bearing. A splined rod is slidably connected to the worm gear, and the splined rod can move axially relative to the worm gear. A rotating disk is fixedly connected to the top of the splined rod. A worm wheel is driven by the worm gear and is coaxially arranged with the drive wheel. This design allows for easy adjustment of the movable gantry's position while simultaneously locking it in place to prevent accidental sliding. The splined rod is connected to the upright via a synchronizing rod.

[0007] Furthermore, the pedal assembly is movably connected to the upright via a sleeve. The upright is inserted into the sleeve, and the sleeve is embedded in the pedal assembly and rises and falls with the pedal assembly. After the upright is inserted into the sleeve, it abuts against the pedal assembly to provide load-bearing capacity, and also ensures easy detachment in the event of a fall from the suspended platform.

[0008] Furthermore, the pedal assembly includes a sliding shoe that slides vertically along a guide rail. The sliding shoe is connected to the pedal, and the guide rail drives the sliding shoe to rise and fall via a pneumatic rod and a drive rope. The drive rope and the pneumatic rod are concealed in corresponding receiving slots on the guide rail, resulting in a relatively compact structure while maintaining strong lifting capacity.

[0009] Furthermore, the movable gantry is located outside the suspended platform, extending beyond the upper and lower end faces of the suspended platform and connecting to the guide rail. The lower end of the suspended platform is provided with a transverse groove, through which the guide rail passes downwards and is fixedly connected to the movable gantry. This reduces the space occupied by the guide rail, pedal assembly, and movable gantry within the suspended platform.

[0010] Furthermore, the pedal can be hinged to the sliding shoe via a connecting shaft. The connecting shaft has a limiting block, and the sliding shoe has a positioning block corresponding to the connecting shaft. When the pedal rotates to a horizontal angle, the limiting block precisely engages with the positioning block. When not in use, the pedal can be stood upright, reducing its occupation of horizontal space.

[0011] Furthermore, the guide rail is equipped with an air pump and a deflation valve, located on the left and right sides of the skis respectively, each with a foot pedal on top. The air pump is connected to the air inlet side of the air compressor via a hose, and the deflation valve is connected to the air outlet side of the air compressor via a hose. The foot pedal is used to control the raising and lowering of the pedals, without interfering with the worker's manual operations.

[0012] Furthermore, the sliding shoe has a groove on the side facing the guide rail, and two braking blocks are installed in the groove. The braking blocks have an oblique "U"-shaped cross-section, with the concave part of the braking block vertically engaging the side wall of the sliding shoe, leaving a gap between the concave part and the sliding shoe. The top of the braking block has a wedge-shaped head, the tip of which inserts between the two braking blocks. A return spring is installed between the two braking blocks, and a pre-tension spring is installed between the wedge-shaped head and the sliding shoe. The elastic force of the pre-tension spring is sufficient to overcome the tension of the return spring, causing the two braking blocks to separate. After separation, the braking blocks can press against the side wall of the guide rail. The guide rail has a braking groove for the braking blocks to press against. When the drive rope is fixedly connected to the wedge-shaped head, it can pull it to the top, preventing the sliding shoe and pedal from falling quickly.

[0013] The beneficial effects of this invention are as follows: This application provides a suspended platform for high-rise building construction. Addressing the safety hazard of workers climbing guardrails for repeated construction work, this invention incorporates a height fine-adjustment function for the pedal assembly and a lateral adjustment function for the movable gantry. This allows workers to flexibly adjust their working position without operating a complex suspended platform lifting system, maintaining both the continuity and efficiency of the work while ensuring workers remain within the effective protection range of the guardrail. This fundamentally reduces workers' motivation to climb guardrails, thereby mitigating the resulting safety risks.

[0014] To address the issue of workers instinctively gripping the platform during a fall and causing strains, this invention innovatively designs a detachable connection structure between the handrail and the footboard assembly. When the platform falls, the handrail automatically detaches from the footboard assembly, and the rotating disc and uprights also detach simultaneously. This effectively severs the mechanical connection between the worker's arm and the falling platform, preventing secondary injuries such as shoulder dislocations and muscle tears caused by the reverse tension generated when the safety rope is taut. This provides more comprehensive safety protection for workers operating at heights. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1, please refer to Figure 1 A suspended platform for high-rise building construction includes a hanging frame 1, a traction rope assembly 2, and a suspended platform 3. The hanging frame 1 is connected to the suspended platform 3 through the traction rope assembly 2. The traction rope assembly 2 includes a traction rope and a winch. The winch winds up and unwinds the safety rope to realize the raising and lowering of the suspended platform 3.

[0019] Please see Figures 1-3The suspended platform 3 includes a suspended platform 310 and a movable gantry 320 that moves laterally along the suspended platform 310. Lateral refers to the direction parallel to the building facade. The upper and lower sides of the suspended platform 310 are respectively provided with an upper support rail 311 and a lower support rail 312. The movable gantry 320 includes a movable plate 321. The side wall of the movable plate 321 is provided with limiting guide wheels 322 corresponding to the upper support rail 311 and the lower support rail 312. The top of the upper support rail 311 and the bottom of the lower support rail 312 are provided with guide grooves. The limiting guide wheels 322 move in the guide grooves. The side wall of the movable plate 321 is also provided with a support guide wheel 323 and a drive wheel 324. The support guide wheel 323 moves along the upper end face of the lower support rail 312 to bear most of the weight of the movable gantry 320. The lower surface of the upper support rail 311 is provided with a rack. The drive wheel 324 rotates to drive the movable gantry 320 to move laterally. The drive wheel 324 is connected to a drive component 360.

[0020] The movable gantry 320 is connected to a vertical guide rail 330. The guide rail 330 is slidably connected to a liftable platform assembly 350. The platform assembly 350 is movably connected to a handrail 340 via a sleeve. The handrail 340 includes an upright 341 and a safety railing 342. The upright 341 is inserted into the sleeve, and the insertion depth is sufficient, or there is damping between the upright 341 and the sleeve, to prevent the upright 341 from accidentally falling when the suspended platform 3 sways. After the sleeve is embedded in the platform assembly 350, it abuts against the platform assembly 350, causing the upright 341 to rise and fall with the platform assembly 350. The upright 341 is fixedly connected to the safety railing 342. The height difference between the safety railing 342 and the platform assembly 350 is not less than 0.8 meters, ensuring effective protection for workers. The guardrail 342 is semi-enclosed with an open rear side. During construction, workers can stand on the platform assembly 350, which is height-adjustable, providing a wider working range and greater freedom of movement. Furthermore, the upright 341 is inserted into the sleeve to ensure stability. When the platform assembly 350 is raised or lowered, workers remain within the protection zone of the guardrail 342. If the suspended platform 3 sways and a worker loses balance, they will first grab the guardrail 342 to maintain their equilibrium. When the suspended platform 3 falls, the handrail 340 can be pulled out of the sleeve, separating from the platform assembly 350 and severing the mechanical connection between the worker's arm and the falling platform, preventing the weight of the suspended platform 3 from concentrating on the arm and causing severe strain.

[0021] The pedal assembly 350 includes a sliding shoe 351 that slides vertically along a guide rail 330. The sliding shoe 351 is connected to a pedal 352. A pneumatic rod 353 and a drive rope 354 are provided on the guide rail 330. One end of the drive rope 354 is fixedly connected to the sliding shoe 351, and the other end is fixedly connected to the guide rail 330. A pulley is provided at the end of the drive rope 354. The pulley pushes the drive rope 354 upward. The pneumatic rod 353 extends and retracts to drive the sliding shoe 351 to rise and fall more quickly. In order to make the structure more compact, the guide rail 330 is provided in a receiving groove corresponding to the pneumatic rod 353 and the drive rope 354.

[0022] To reduce the space occupied by the guide rail 330, pedal assembly 350, and movable gantry 320 within the suspended platform 310, the movable gantry 320 is located outside the suspended platform 3. The movable gantry 320 extends beyond the upper and lower end faces of the suspended platform 310 and connects to the guide rail 330. Since the upper end of the suspended platform 310 is open, the upper end of the movable gantry 320 can be directly and fixedly connected to the upper end of the guide rail 330. The lower end of the suspended platform 310 is provided with a transverse groove 313, through which the guide rail 330 passes downward and is fixedly connected to the movable gantry 320.

[0023] Please see Figure 2 and Figure 5 To further reduce the space occupied by the suspended platform 310, the pedal 352 can be hinged to the sliding shoe 351 via the connecting shaft 3512. When not in use, the pedal 352 can be erected to reduce the occupation of horizontal space. The connecting shaft 3512 is provided with a limiting block 3513, and the sliding shoe 351 is provided with a positioning block 3514 corresponding to the connecting shaft 3512. When the pedal 352 rotates to a horizontal angle, the limiting block 3513 just locks the positioning block 3514, restricting the continued rotation of the pedal 352. When a worker stands on the pedal 352, the pedal 352 can effectively bear the weight.

[0024] Please see Figure 4 The guide rail 330 is equipped with an air pump 355 and an air release valve 356. The air pump 355 and the air release valve 356 are located on the left and right sides of the sliding shoe 351 (when the person is facing the building), and each of them is equipped with a foot pedal. When the foot pedal 352 is horizontal, it is almost at the same height as the upper surface of the sliding shoe 351. The air pump 355 is connected to the air inlet side of the air pressure rod 353 through a hose, and the air release valve 356 is connected to the air outlet side of the air pressure rod 353 through a hose. When the person repeatedly steps on the foot pedal corresponding to the air pump 355, the air pressure rod 353 is inflated, which extends it and thus raises it. When the foot pedal corresponding to the air release valve 356 is stepped on, the air release valve 356 releases air at a uniform speed and slowly, and the air pressure rod 353 retracts, thus slowly lowering the height.

[0025] When the pipeline ruptures or the pneumatic rod 353 fails, to prevent the pedal 352 from suddenly dropping, the sliding shoe 351 has a groove on the side facing the guide rail 330. Two brake blocks 359 are installed in the groove. The brake blocks 359 have an oblique "U"-shaped cross-section. The recessed part of the brake block 359 is vertically engaged with the side wall of the sliding shoe 351, with a gap 3511 between the recessed part and the sliding shoe 351, allowing the brake blocks 359 to slide both vertically and laterally. A wedge-shaped head 358 is provided at the top of the brake blocks 359, with its tip inserted between the two brake blocks 359. A return spring 357 is provided between the two brake blocks 359, keeping the brake blocks 359 against the lower side of the wedge-shaped head 358 and preventing them from contacting the guide rail 330. A preload spring 3510 is provided between the wedge-shaped head 358 and the sliding shoe 351. The preload spring 3510... The force is sufficient to overcome the elastic force of the return spring 357, causing the two brake blocks 359 to separate. After separation, the brake blocks 359 can press against the side wall of the guide rail 330. The guide rail 330 is provided with a brake groove for the brake blocks 359 to press against. In this embodiment, the brake groove is a receiving groove. After the brake blocks 359 press against the guide rail 330, the friction force causes the brake blocks 359 to move upward and press against the wedge head 358. The greater the gravity, the greater the force between the brake blocks 359 and the wedge head 358, and the tighter the brake blocks 359 are against the guide rail 330, the greater the friction force, which prevents the slipper 351 and the pedal 352 from falling quickly. When the pneumatic rod 353 is not in failure, the gravity is mainly borne by the drive rope 354. When the drive rope 354 is fixedly connected to the wedge head 358, it pulls it to the top. The brake blocks 359 do not contact the guide rail 330, and the slipper 351 can rise and fall freely.

[0026] Please see Figure 2 and Figure 3 The driving component 360 includes a worm gear 361, which is movably connected to the moving plate 321 via a bearing. A splined rod 362 is slidably connected to the worm gear 361. The splined rod 362 can move axially relative to the worm gear 361 and can also rotate the worm gear 361. A rotating disk 364 is fixedly connected to the top of the splined rod 362. The worker rotates the splined rod 362 by rotating the disk 364. A worm wheel 365 is driven by the worm gear 361. The worm wheel 365 is coaxially arranged with the driving wheel 324. The rotating disk 364 drives the driving wheel 324 to rotate, thereby adjusting the position of the moving gantry 320. At the same time, the self-locking ability of the worm wheel and worm gear is used to lock the position of the moving gantry 320 and prevent the moving gantry 320 from sliding accidentally.

[0027] To facilitate the operation of the rotating disc 364, the spline rod 362 is connected to the upright rod 341 via the synchronizing rod 363. The rotating disc 364 rises and falls synchronously with the upright rod 341. At the same time, when the suspended platform falls, if the worker holds onto the rotating disc 364, the rotating disc 364 and the upright rod 341 will fall off synchronously, avoiding injury to the worker.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
