Description

Technical Field

[0001] This invention relates to the field of escape device technology, and in particular to a portable rapid escape device for high-rise buildings. Background Technology

[0002] Today, due to the need for efficient use of land resources, the number of high-rise buildings is constantly increasing. In recent years, sudden catastrophic events in high-rise buildings have gradually attracted widespread attention from all sectors of society. Various escape devices for high-rise buildings have been developed and proposed. The application of these devices has effectively improved the escape success rate of high-rise residents in emergency situations.

[0003] Currently, various escape devices have emerged on the market to meet the needs of high-rise building escape. Most of these devices use ropes as the core load-bearing and descent components, relying on ropes to pull escape carriers (such as escape pods and safety belts) to transfer people from high-rise buildings to the ground.

[0004] However, during the actual descent, especially at higher floors, the wind can easily cause violent shaking, leading to escapees colliding with the building's exterior walls or falling due to loss of control of the descent speed.

[0005] Accordingly, this application proposes a portable rapid escape device for high-rise buildings. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable rapid escape device for high-rise buildings.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A portable high-rise building rapid escape device includes a fixed frame, a warning component, an anti-sway component, and a slow descent component. The fixed frame is provided with a support pulley, the support pulley is provided with a first hook chain, a descent frame is provided below the support pulley, and two damping pulleys are provided below the support pulley. The warning component is used to alert people downstairs to a potential danger. The anti-sway component is used to prevent the descent frame from tilting due to wind force; The descent control assembly is used to prevent the descent frame from accelerating too quickly during descent.

[0008] Preferably, the anti-sway assembly includes two sliding plates, two cylinders, and a wind direction sensor. The wind direction sensor is fixedly installed on the descent frame, the two cylinders are fixedly installed on the fixed frame, and the two sliding plates are slidably connected to the fixed frame.

[0009] Preferably, the warning assembly includes two searchlights, two second gears, and two half gears. The two second gears are rotatably connected to two sliding plates, the two half gears are rotatably connected to two sliding plates, and the two searchlights are fixedly mounted on the second gears.

[0010] Preferably, the descent control assembly includes two frame plates, two worm gears, two worm wheels, two electric telescopic rods, two second bevel gears, and two first bevel gears. The two frame plates are respectively fixedly connected to damping pulleys, the two worm wheels are respectively rotatably connected to the two frame plates, the two electric telescopic rods are respectively fixedly installed on the two worm wheels, the two second bevel gears are respectively fixedly connected to the output ends of the two electric telescopic rods, and the two first bevel gears are respectively fixedly connected to the handles of the two damping pulleys.

[0011] Preferably, the cylinder output end is fixedly connected to the sliding plate, a torsion spring is provided at the connection between the second gear and the sliding plate, the second gear meshes with the saw teeth on the half gear, a rotating shaft is fixedly connected to the half gear, the second bevel gear can mesh with the first bevel gear, and the worm is located on one side of the worm wheel.

[0012] Preferably, the end of the rotating shaft away from the half gear is fixedly connected to the inner pulley of the damping pulley, a rotating roller is fixedly connected to the first gear, the rotating roller is rotatably connected to the damping pulley, a second hook chain is provided on the damping pulley, and a pulley hook is provided on the second hook chain.

[0013] Preferably, the two pulley hooks are respectively hooked onto the descending frame, one end of the first hook chain is hooked onto the descending frame, the worm is fixedly connected to the rotating roller, the worm is meshed with the worm wheel, and a support rod is fixedly connected to the sliding plate.

[0014] Preferably, the support rod is fixedly connected to the damping pulley, the first gear and the half gear mesh with saw teeth, and the damping pulley is provided with a scale.

[0015] Preferably, a fixing plate is fixedly connected to the fixing frame, and the fixing plate is provided with a plurality of bolt holes.

[0016] Preferably, a mounting bracket is fixedly connected to the fixed frame, and the supporting pulley is mounted on the mounting bracket.

[0017] The present invention has the following beneficial effects: 1. Through the warning component, when the lowering frame descends, the inner pulley of the damping pulley causes the rotating shaft to drive the half gear to rotate. The half gear intermittently meshes with the second gear, causing the second gear to rotate. Subsequently, the torsion spring can reset the second gear, allowing the searchlight to swing back and forth, thereby enhancing the visual stimulation to people downstairs and expanding the warning range to cover more areas downstairs, so that people who are escaping can be rescued in time after falling.

[0018] Second, through the anti-sway component, when the surrounding wind speed is too high and the wind direction causes the descent frame to tilt during descent, the wind direction sensor transmits a signal to the control center. The control center can control the cylinders, causing the output end of the cylinder on the tilted side to drive the sliding plate to slide upward, which in turn causes the damping pulley to pull the tilted side of the descent frame upward. At the same time, the control center controls the cylinder on the other side, causing the output end of the cylinder on that side to drive the sliding plate to slide downward, which in turn causes the corresponding damping pulley to move downward, thereby correcting the tilt of the descent frame and preventing accidents to the escape personnel caused by the tilt of the descent frame due to strong winds.

[0019] Third, after adjusting the deceleration torque of the damping pulley through the descent assembly, the electric telescopic rod drives the second bevel gear to mesh with the first bevel gear. When personnel begin to descend in the descent frame, the half gear intermittently drives the first gear to rotate, causing the rotating roller to intermittently drive the second bevel gear to rotate through the worm and worm wheel. This causes the first bevel gear to slowly adjust the state of the damping pulley handle, changing the damping force of the damping pulley, thereby gradually slowing down the descent speed of the descent frame. This prevents the descent frame from falling faster and faster due to the continuous action of gravity, ensuring that personnel remain within a safe speed range during the descent.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Example 1: Reference Figure 1 , Figure 2 and Figure 3 A portable high-rise building rapid escape device includes a fixed frame 1, a warning component, an anti-sway component, and a slow-descent component. A fixed plate 2 is fixedly connected to the fixed frame 1. The fixed plate 2 has several bolt holes for bolts to pass through. The device is fixedly installed in front of load-bearing structures such as balcony railings and window sills using the fixed plate 2. It has wide application locations and is easy to move and install. The fixed frame 1 is equipped with a support pulley 24 for supporting a first hook chain 8. The first hook chain 8 is mounted on the support pulley 24. A descending frame 3 is located below the support pulley 24 to carry the escaping personnel. Two damping pulleys 10 are located below the support pulley 24 to provide damping force to control the descent speed. The fixed frame 1 is fixed with... A mounting bracket 7 is fixedly connected to the frame 1 for mounting the support pulley 24. The support pulley 24 is mounted on the mounting bracket 7 and fixed to the frame 1 by the mounting bracket 7. A second hook chain 25 is provided on the damping pulley 10, which connects the damping pulley 10 and the descending frame 3 to transmit damping force. A pulley hook 12 is provided on the second hook chain 25, which connects the second hook chain 25 and the descending frame 3 to achieve detachable hooking. The two pulley hooks 12 are hooked on the descending frame 3 respectively. The hooking makes the second hook chain 25 and the descending frame 3 form traction. One end of the first hook chain 8 is hooked on the descending frame 3 to ensure that the descending frame 3 remains stable when descending. The damping pulley 10 is provided with a scale to help to intuitively judge the adjustment range of the damping force.

[0024] The warning component is used to alert people downstairs to a potential hazard. Anti-sway components are used to prevent the descent frame 3 from tilting due to wind force; The descent control assembly is used to prevent the descent frame 3 from accelerating too fast during descent.

[0025] The anti-sway assembly includes two sliding plates 6, two cylinders 5, and a wind direction sensor 4. The wind direction sensor 4 is fixed to the descent frame 3, detects the wind direction, and transmits a signal. The wind direction sensor 4 is fixedly installed on the descent frame 3 to detect the wind direction around the descent frame 3 in real time. The two cylinders 5 are fixedly installed on the fixed frame 1. The two sliding plates 6 are slidably connected to the fixed frame 1 and can slide along the fixed frame 1 to adjust their positions. The output end of the cylinder 5 is fixedly connected to the sliding plate 6. The action of the cylinder 5 directly drives the sliding plate 6 to move. Two damping pulleys 10 are respectively set on the two sliding plates 6 and adjust their positions as the sliding plates 6 move, thereby correcting the tilt of the descent frame 3.

[0026] In this embodiment, when the surrounding wind speed is too high during the descent of the descent frame 3, and the wind direction causes the descent frame 3 to tilt, the wind direction sensor 4 transmits a signal to the control center. The control center can control the cylinder 5, so that the output end of the cylinder 5 on the tilted side drives the sliding plate 6 to slide upward, thereby causing the damping pulley 10 to pull the tilted side of the descent frame 3 upward. At the same time, the control center controls the cylinder 5 on the other side, so that the output end of the cylinder 5 on that side drives the sliding plate 6 to slide downward, thereby causing the corresponding damping pulley 10 to move downward, thus correcting the tilted state of the descent frame 3 and preventing accidents to the escape personnel caused by the tilting of the descent frame 3 due to strong winds.

[0027] Example 2: Unlike Example 1, referring to Figure 1 , Figure 2 , Figure 3 and Figure 5 This embodiment also has the following further features: The warning assembly includes two spotlights 9, two second gears 15, and two half gears 13. The two second gears 15 are rotatably connected to two sliding plates 6, and rotate with the sliding plates 6 as support. The two half gears 13 are rotatably connected to two sliding plates 6, and rotate with the sliding plates 6 as support. The two spotlights 9 are fixedly installed on the second gears 15. The spotlights 9 are used to emit warning light to remind people downstairs and move synchronously with the second gears 15. A torsion spring is provided at the connection between the second gear 15 and the sliding plate 6. When the second gear 15 rotates, it can drive the second gear 15 to reset, so that the second gear 15 returns to its initial position when it is not engaged. The second gear 15 meshes with the sawtooth on the half gear 13, and the power is transmitted through the sawtooth, so that the half gear 13 drives the second gear 15 to rotate. A rotating shaft 11 is fixedly connected to the half gear 13 and rotates synchronously with the rotating shaft 11. The end of the rotating shaft 11 away from the half gear 13 is fixedly connected to the inner pulley of the damping pulley 10 and rotates with the inner pulley of the damping pulley 10, transmitting power to the half gear 13. A support rod 16 is fixedly connected to the sliding plate 6 and is fixedly connected to the damping pulley 10, providing support for the damping pulley 10.

[0028] In this embodiment, when the lowering frame 3 is lowered, the inner pulley of the damping pulley 10 causes the rotating shaft 11 to drive the half gear 13 to rotate. The half gear 13 intermittently meshes with the second gear 15, causing the second gear 15 to rotate. Subsequently, the torsion spring can reset the second gear 15, allowing the searchlight 9 to swing back and forth, thereby enhancing the visual stimulation to people downstairs and expanding the warning range to cover more areas downstairs, so that people who are escaping can be rescued in time after falling.

[0029] Example 3: Reference Figure 3 , Figure 4 and Figure 5 Compared to Embodiment 1 and Embodiment 2, in this embodiment: The slow-descent assembly includes two frame plates 23, two worm gears 21, two worm wheels 22, two electric telescopic rods 20, two second bevel gears 19, and two first bevel gears 18. The two frame plates 23 are fixedly connected to the damping pulleys 10, and the two worm wheels 22 are rotatably connected to the two frame plates 23. The two electric telescopic rods 20 are fixedly installed on the two worm wheels 22 and can rotate with the rotation of the worm wheels 22. The two second bevel gears 19 are fixedly connected to the output ends of the two electric telescopic rods 20 and can move with the extension and retraction of the electric telescopic rods 20 to engage or disengage with the first bevel gears 18. The two first bevel gears 18 are fixedly connected to the handles of the two damping pulleys 10. When the first bevel gears 18 rotate, they can directly drive the handles of the damping pulleys 10 to adjust and change the damping force.

[0030] The second bevel gear 19 can mesh with the first bevel gear 18. When meshing, the power of the second bevel gear 19 can be transmitted to the first bevel gear 18, thereby enabling the adjustment of the damping pulley 10 handle. The worm 21 is located on one side of the worm wheel 22. The rotating roller 17 is rotatably connected to the damping pulley 10 and rotates with the damping pulley 10 as support. The rotating roller 17 is fixedly connected to the first gear 14. When the first gear 14 rotates, it can drive the rotating roller 17 to rotate synchronously. The worm 21 is fixedly connected to the rotating roller 17 and can rotate synchronously with the rotating roller 17. The worm 21 is meshed with the worm wheel 22. Through meshing, the rotational power of the worm 21 is transmitted to the worm wheel 22, driving the worm wheel 22 to rotate. The first gear 14 meshes with the sawtooth on the half gear 13. When the half gear 13 rotates, it drives the first gear 14 to rotate through the sawtooth.

[0031] In this embodiment, after adjusting the deceleration torque of the damping pulley 10, the electric telescopic rod 20 drives the second bevel gear 19 to mesh with the first bevel gear 18. When the personnel begin to descend on the descent frame 3, the half gear 13 intermittently drives the first gear 14 to rotate, causing the rotating roller 17 to intermittently drive the second bevel gear 19 to rotate through the worm 21 and worm wheel 22. This causes the first bevel gear 18 to slowly adjust the state of the handle of the damping pulley 10, changing the damping force of the damping pulley 10, thereby gradually increasing the descent speed of the descent frame 3. This prevents the descent frame 3 from falling faster and faster due to the continuous action of gravity, ensuring that the personnel are always within a safe speed range during the descent.

[0032] Working principle: When danger occurs and escape is needed, the handle of the damping pulley 10 is swung according to the weight of the person to adjust it to the corresponding scale. This activates the electric telescopic rod 20, which drives the second bevel gear 19 to mesh with the first bevel gear 18. The person then enters the descent frame 3. Under the weight of the person and the action of the damping pulley 10, the person slowly descends on the descent frame 3. At this time, the pulley inside the damping pulley 10 causes the rotating shaft 11 to drive the half gear 13 to rotate. The half gear 13 intermittently drives the first gear 14 to rotate, causing the rotating roller 17 to intermittently drive the second bevel gear 19 to rotate through the worm gear 21 and worm wheel 22. This causes the first bevel gear 18 to slowly adjust the state of the handle of the damping pulley 10, changing the damping force of the damping pulley 10, thereby gradually increasing the descent speed of the descent frame 3. This prevents the descent frame 3 from falling faster and faster due to continuous gravity, ensuring that the person remains within a safe speed range during the descent. Simultaneously, when… When the descent frame 3 descends, the half gear 13 intermittently meshes with the second gear 15, causing the second gear 15 to rotate. Subsequently, the torsion spring can reset the second gear 15, allowing the searchlight 9 to swing back and forth, thereby enhancing the visual stimulation for people below and expanding the warning range to cover more areas below, ensuring that people escaping can be rescued in time after falling. In addition, when the wind speed around the descent frame 3 is too high and the wind direction causes the descent frame 3 to tilt, the wind direction sensor 4 transmits a signal to the control center. The control center can control the cylinder 5, causing the output end of the cylinder 5 on the tilted side to drive the sliding plate 6 to slide upward, thereby causing the damping pulley 10 to pull the tilted side of the descent frame 3 upward. At the same time, the control center controls the cylinder 5 on the other side, causing the output end of the cylinder 5 on that side to drive the sliding plate 6 to slide downward, thereby causing the corresponding damping pulley 10 to move downward, thus correcting the tilt of the descent frame 3 and preventing accidents to people escaping due to the tilt of the descent frame 3 caused by strong winds.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
