Abstract
Description
Technical Field
[0001] This invention relates to the field of fall-prevention construction platform technology, and in particular to fall-prevention construction platforms for high-rise building construction. Background Technology
[0002] With the rapid development of the construction industry and increasingly taller buildings, the use of lifting platforms is expanding accordingly. Besides scaffolding, projects often require temporary construction platforms to meet the needs of large-scale high-altitude operations and worker mobility. However, scaffolding cannot be raised or lowered, making it difficult to meet usage requirements. Therefore, to use lifting platforms to transport people, the problem of fall prevention must be solved.
[0003] Construction hoisting platforms are commonly referred to as construction hoists, but the definition of construction hoisting is broader, and construction platforms also belong to the construction hoisting category. Construction hoists are frequently used personnel and cargo-carrying construction machinery in construction. With the continuous emergence of a large number of high-rise and super high-rise buildings, the height of buildings is increasing day by day, which brings considerable challenges to the application of construction hoists.
[0004] CN212984564U discloses a building construction platform, including a base, a guide column fixedly mounted on the base, a support plate slidably mounted on the guide column, and a lifting plate slidably mounted on the guide column in a vertical direction. A first drive assembly for driving the lifting plate to move up and down is provided on the guide column. During the use of the construction platform, workers stand on the support plate and raise it. When construction materials on the ground are needed, they are placed on the lifting plate, and the first drive assembly is activated to lift the materials. This patent facilitates workers in taking construction materials to the support plate, and after use, the materials are lowered back to the ground using a hoisting rope, avoiding the accumulation of too many materials on the support plate and greatly improving construction efficiency. However, the safe use of construction hoisting platforms is related to the progress and quality of construction, but it also poses significant safety hazards. The aforementioned patent uses a hoisting motor to drive the hoisting rope to achieve platform lifting. With prolonged use, the hoisting rope is prone to aging and breakage. The aging and eventual breakage of the hoisting rope is a gradual process that is often difficult to detect in a timely and effective manner. Once the hoisting rope breaks, the load-bearing plate has no fall protection measures, and the injury to the personnel on it is unimaginable. Therefore, traditional construction hoisting platforms that use hoisting ropes are not very safe, and the protection measures for construction personnel are inadequate, making it very dangerous for construction personnel to work on the exterior of tall buildings.
[0005] CN212801164U A lifting platform for bridge construction includes a support frame consisting of four corresponding columns, a top plate, and a bottom plate. The top plate has first slide rails and first sliders on both sides of its bottom surface, and the bottom plate has second slide rails and second sliders on both sides of its top surface. A running frame is provided between the first and second sliders, and a support plate is provided within the running frame. Two support blocks are fixedly installed on the support plate, and bearings are correspondingly provided on the two support blocks. A rotating shaft is provided between the inner rings of the two bearings. A drive motor is provided on one side of the rotating shaft, and a winding wheel is provided on the rotating shaft. A first steel wire rope is wound on the winding wheel. A support frame is provided below the first steel wire rope, and second steel wire ropes are provided at the four corners of the top of the support frame. Third slide rails and third sliders are provided on both side plates. The platform also includes a drive cylinder and a controller. The aforementioned patent has a wide maintenance range, a high degree of automation, and is easy to move, effectively improving the work efficiency of bridge maintenance and construction. However, it improves the construction safety of construction workers by setting safety belts on hooks to prevent workers from falling. When the first steel wire rope breaks, the construction workers will be suspended in the air, increasing the difficulty of subsequent rescue. Summary of the Invention
[0006] To address the shortcomings of existing technologies, a fall arrest platform for high-rise building construction is provided. When the steel wire rope breaks, it can cushion the load-bearing box carrying construction workers, improving the safety of construction workers. At the same time, after the load-bearing box is cushioned, it can be lowered slowly, reducing the difficulty of subsequent rescue.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is a fall-prevention construction platform for high-rise building construction, comprising a construction frame consisting of a base plate, a top plate, and four columns correspondingly arranged between the base plate and the top plate, and a lifting device arranged on the top plate. A carrying box for carrying construction personnel is provided inside the construction frame and connected to the lifting device. A slide rail is provided along the length of the four columns, and a first slider connected to the side walls of the carrying box is provided on the slide rail. A first elastic buffer device and a buffer plate are provided below the carrying box. The first elastic buffer device is configured to prevent fall when the buffer plate reaches a predetermined position. The system includes a locking device that locks the buffer plate, an air cushion at the bottom of the buffer plate, a second elastic buffer device connected to the slide rail via a second slider at the bottom of the construction frame, a buffer box for receiving the falling load box on the second elastic buffer device, steep slope deceleration components on the side walls of the buffer box, a load block slidably connected to the side wall of the buffer box inside the buffer box, elastic rods for sliding down the steep slope deceleration components on the side walls of the load block, and a first locking hole on the side wall of the buffer box below the steep slope deceleration components for locking the elastic rod when it descends to a predetermined position.
[0008] The aforementioned fall-prevention construction platform for high-rise building construction includes a steep slope deceleration component comprising a deceleration chamber corresponding to the two side walls of the buffer box, and a wedge-shaped block arranged along the height direction of the deceleration chamber.
[0009] The aforementioned high-rise building construction anti-fall platform includes an elastic rod comprising positioning cavities on both sides of the bearing block and a positioning rod disposed within the positioning cavity. A positioning spring is provided between one end of the positioning rod and the positioning cavity to connect the two.
[0010] The aforementioned high-rise building construction anti-fall platform includes a first elastic buffer device comprising fixed pipes on both sides of the bottom of the bearing box and telescopic pipes inside the fixed pipes. The two sides of the buffer plate are fixedly connected to the two telescopic pipes. Multiple first buffer springs are provided between the bottom of the bearing box and the buffer plate to connect the two.
[0011] The aforementioned high-rise building construction anti-fall platform includes a locking component comprising a fixed cavity formed on a telescopic tube and a locking rod disposed within the fixed cavity. A locking spring is provided between one end of the locking rod and the fixed cavity for connecting the two. A second locking hole is provided on the fixed tube for cooperating with the locking rod.
[0012] The aforementioned high-rise building construction platform for preventing falls includes a second elastic buffer device comprising a lifting plate connected to a second slider at both ends, and a plurality of second buffer springs located at the bottom of the lifting plate.
[0013] The aforementioned high-rise building construction anti-fall platform has a first sponge pad layer at the bottom of the bearing block, and a first locking hole on the side wall of the buffer box below the steep slope deceleration component for locking the elastic rod when it descends to a predetermined position.
[0014] The aforementioned fall-prevention construction platform for high-rise building construction has a second sponge pad layer at the bottom of the buffer plate.
[0015] The beneficial effects of the fall-prevention construction platform for high-rise building construction of this invention are that, by setting up a first elastic buffer device and a second elastic buffer device, the support box carrying construction personnel can be cushioned when the steel wire rope breaks, thereby improving the construction safety of the personnel. After the first and second elastic buffer devices cushion the support box, the compression of the air cushion by the first and second elastic buffer devices achieves a slow descent of the support box, thereby reducing the difficulty of subsequent rescue.
[0016] By incorporating a buffer box, the falling load-bearing box is transformed from a long, rapid descent into a short, slow descent. After the air cushion on the falling load-bearing box contacts the load-bearing block, the elastic friction between the elastic rod and the steep slope deceleration component causes the load-bearing box to slow down multiple times, thus cushioning the fall. Furthermore, the distance between the load-bearing block and the bottom of the buffer box gradually decreases, preventing the air cushion on the falling load-bearing box from directly contacting the second elastic buffer device. This reduces the shock felt by the workers inside the load-bearing box from direct contact with the second elastic buffer device during a rapid descent. Simultaneously, it improves the protection of the air cushion, preventing it from exploding. The buffer box, in conjunction with the second elastic buffer device and the air cushion, not only reduces the shock felt by the workers inside the load-bearing box but also reduces the impact force of the falling load-bearing box on the second elastic buffer device. This prevents the second elastic buffer device from experiencing excessive rebound due to a large impact force, which could cause the load-bearing box to vibrate violently multiple times due to excessive rebound, and also reduces the risk of damage to the second elastic buffer device. In other words, by setting up a buffer box, the falling carrier is changed from a long-distance, rapid descent to a short-distance, slow descent. Then, by setting up an air cushion, the height of the carrier is gradually reduced, thus achieving a slow descent of the carrier and reducing the difficulty of subsequent rescue.
[0017] After the first elastic buffer device, the second elastic buffer device, and the buffer box buffer the carrier box carrying the construction personnel, a locking device is installed so that the first elastic buffer device loses its elasticity after buffering the carrier box, and can rigidly press down on the air cushion. Meanwhile, the rebound force of the second elastic buffer device can elastically press up on the air cushion. The rigid downward pressure and elastic upward pressure not only ensure the compression effect of the air cushion, but also control the air cushion's exhaust speed, so that the falling carrier box descends slowly, preventing the shock to the construction personnel inside the carrier box when the rapidly falling carrier box contacts the carrier block. Moreover, the rigid downward pressure and elastic upward pressure control the air cushion's exhaust speed, which also protects the air cushion and prevents it from exploding.
[0018] By setting a first sponge pad at the bottom of the load-bearing block, the vibration of the load-bearing box is further reduced and the comfort is improved. A first locking hole is set on the side wall of the buffer box below the steep slope deceleration component to lock the elastic rod when it descends to the predetermined position. This ensures that after the load-bearing block slowly descends to the predetermined position, the first sponge pad no longer has elasticity, thus preventing the elastic first sponge pad from affecting the effect of the second elastic buffer device on the elastic pressure of the air cushion.
[0019] By adding a second sponge pad layer at the bottom of the buffer plate, the vibration of the load-bearing box is further reduced, and the protection of the air cushion is improved. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0030] Example 1
[0031] like Figure 1-6As shown, a fall-prevention construction platform for high-rise building construction includes a construction frame consisting of a base plate 1, a top plate 2, and four columns 3 correspondingly located between the base plate 1 and the top plate 2, as well as a lifting device 4 located on the top plate 1. A carrying box 5 for carrying construction personnel is provided inside the construction frame and connected to the lifting device 4. The lifting device is a winch, and the carrying box 5 is connected to the winch via a steel wire rope 6. This is existing technology and will not be described further. A slide rail 7 is provided along the length of the four columns 3. A first slider 8 connected to the side walls of the carrying box 5 is provided on the slide rail 7. A first elastic buffer device and a buffer plate 9 are provided below the carrying box 5. The first elastic buffer device has a locking element for locking the buffer plate 9 when it reaches a predetermined position. An air cushion 10 is provided at the bottom of the buffer plate 9. The air cushion 10 is an air cushion with multiple exhaust ports that can be opened by airflow. Air cushions with multiple exhaust ports that can be opened by airflow are existing technology and will not be described further. A second elastic buffer device is provided at the bottom of the construction frame, connected to the slide rail 7 via a second slider 11. A buffer box 12 for catching the falling load box 5 is provided on the second elastic buffer device. Steep slope deceleration components are correspondingly provided on the two side walls of the buffer box 12. A load block 13 is provided inside the buffer box 12, slidably connected to the side walls of the buffer box 12. The load block 13 is slidably connected to each side wall of the buffer box 12, which can limit the movement of the load block 13, allowing it to run vertically. Elastic rods are correspondingly provided on the two side walls of the load block 13 for sliding down on the steep slope deceleration components.
[0032] The steep slope deceleration assembly includes descent chambers 15 corresponding to the two side walls of the buffer box 12, and wedge-shaped blocks 16 arranged along the height direction of the descent chambers 15. By setting up the buffer box, the falling load box is transformed from a long-distance rapid descent to a short-distance slow descent. After the air cushion on the falling load box contacts the load block, the elastic friction between the elastic rod and the steep slope deceleration assembly causes the load box to decelerate multiple times, thus buffering the falling load box. Furthermore, the distance between the load block and the bottom of the buffer box gradually decreases, preventing the air cushion on the falling load box from directly contacting the second elastic buffer device quickly, reducing the vibration felt by the construction personnel inside the load box caused by the rapid descent of the load box directly contacting the second elastic buffer device. At the same time, it also improves the protection of the air cushion and prevents the air cushion from exploding. The buffer box, in conjunction with the second elastic buffer device and the air cushion, not only reduces the vibration felt by the construction personnel inside the load-bearing box, but also reduces the impact force of the falling load-bearing box on the second elastic buffer device. This prevents the second elastic buffer device from experiencing excessive rebound due to a large impact force, thus avoiding repeated large-amplitude up-and-down vibrations of the load-bearing box and reducing damage to the second elastic buffer device. In other words, by setting up the buffer box, the falling load-bearing box is transformed from a long, rapid descent to a short, slow descent. Then, the air cushion gradually lowers the height of the load-bearing box, achieving a slow descent and reducing the difficulty of subsequent rescue.
[0033] The elastic rod includes positioning cavities 17 opened on both sides of the bearing block 13, and positioning rod 18 disposed in the positioning cavity 17. A positioning spring 19 for connecting the two is provided between one end of the positioning rod 18 and the positioning cavity 17.
[0034] The first elastic buffer device includes fixed tubes 20 on both sides of the bottom of the bearing box 5, and telescopic tubes 21 inside the fixed tubes 20. The two sides of the buffer plate 9 are fixedly connected to the two telescopic tubes 21. A plurality of first buffer springs 22 are provided between the bottom of the bearing box 5 and the buffer plate 9 to connect the two.
[0035] The locking component includes a fixed cavity 23 formed on the telescopic tube 21 and a locking rod 24 disposed within the fixed cavity 23. A locking spring 25 is provided between one end of the locking rod 24 and the fixed cavity 23 to connect the two. A second locking hole 26 is provided on the fixed tube 20 to cooperate with the locking rod 24. After the first elastic buffer device, the second elastic buffer device, and the buffer box buffer the carrier box carrying the construction personnel, the locking component ensures that the first elastic buffer device, after buffering the carrier box, no longer has elasticity and can rigidly press down on the air cushion. The rebound force of the second elastic buffer device can elastically press up on the air cushion. The rigid pressing down and the elastic pressing up ensure the compression effect of the air cushion and control the air cushion's exhaust speed, so that the falling carrier box descends slowly, preventing the shock to the construction personnel inside the carrier box when the rapidly falling carrier box contacts the carrier block. Moreover, the rigid pressing down and the elastic pressing up control the air cushion's exhaust speed, which also protects the air cushion and prevents it from exploding.
[0036] The second elastic buffer device includes a lifting plate 27 connected to the second slider 11 at both ends, and a plurality of second buffer springs 28 disposed at the bottom of the lifting plate 27.
[0037] Example 2
[0038] The parts of this embodiment that are the same as those in Embodiment 1 will not be repeated here. The difference is that, for example... Figure 7-9 As shown, a first sponge pad 29 is provided at the bottom of the bearing block 13, and a first locking hole 14 is provided on the side wall of the buffer box 12 below the steep slope deceleration component to lock the elastic rod when it descends to a predetermined position. By providing a first sponge pad at the bottom of the bearing block, the vibration of the bearing box is further reduced, and the comfort is improved. The first locking hole on the side wall of the buffer box below the steep slope deceleration component ensures that the first sponge pad loses its elasticity after the bearing block slowly descends to the predetermined position, thus preventing the elastic first sponge pad from affecting the elastic pressure effect of the second elastic buffer device on the air cushion.
[0039] A second sponge pad 30 is provided at the bottom of the buffer plate 9. By providing a second sponge pad at the bottom of the buffer plate, the vibration of the load-bearing box is further reduced, and the protection of the air cushion is improved.
[0040] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
