[0002] After a fire breaks out, some people are unable to escape in time and usually wait for rescue at the building's windows.
[0003] Existing emergency escape descent devices are usually some distance from the window when they rise to the window where the trapped person is located, which increases the difficulty of rescue. In addition, the trapped person needs to climb up the window to get onto the lifting device. If the balance is not well controlled during this process, it is easy to cause danger. Moreover, it is more difficult for the elderly, children and other people with mobility difficulties to climb up the window, resulting in a slow evacuation speed. Summary of the Invention

In addition, the trapped person needs to climb onto the window to get onto the lifting device, which can be dangerous if the balance is not well controlled. Furthermore, it is difficult for the elderly, children and other people with mobility difficulties to climb onto the window, resulting in a slow evacuation speed.

[0010] The deployment unit, which connects to the docking unit, is used to enable trapped personnel to safely and quickly board the docking unit.
[0011] Furthermore, a walking opening is provided on the outer wall of one side of the enclosure.
[0012] Furthermore, the monitoring mechanism includes an electric push rod installed inside the enclosure and a camera installed at the extended end of the electric push rod, the camera having intercom and angle adjustment functions.
[0013] Furthermore, the docking mechanism includes a chute formed inside the transfer platform, multiple hydraulic cylinders installed inside the chute, and a docking platform that slides inside the chute.
[0014] The extended ends of all of the hydraulic cylinders are fixedly connected to one end of the docking platform;
[0015] The other end of the docking platform slides out to the outside of the adapter.
[0016] Furthermore, the protective mechanism includes two columns fixed to the top of the other end of the docking platform and two protective ropes respectively fixed to the top of the two columns;
[0017] The other ends of both protective ropes are fixed to the outer wall of the enclosure, and the two protective ropes are located on both sides of the passageway.
[0018] Furthermore, the docking platform has a hollow structure, and an opening is provided at the end of the docking platform away from the hydraulic cylinder.
[0019] Furthermore, the delivery mechanism includes a climbing plate disposed inside the docking platform, multiple pedals installed on the top of the climbing plate, a limiting component for limiting the climbing plate, and a driving component for driving the climbing plate to move.
[0020] One end of the climbing plate extends to the outside of the docking platform.
[0021] Furthermore, the drive assembly includes two fixed seats respectively fixed to the inner walls on both sides of the docking platform, a connecting block disposed between the two fixed seats, and a plurality of first springs fixed to the outer wall of the docking platform near the hydraulic cylinder.
[0022] One end of each of the two fixed seats extends to the outside of the docking platform. The outer wall of each of the two fixed seats on the opposite side is provided with a movable groove along its length. A slider is slidably connected inside each of the two movable grooves. A drive shaft is rotatably connected between the two sliders. The connecting block is fixedly sleeved on the outside of the drive shaft and is fixedly connected to the climbing plate.
[0023] A push plate is fixed to the other end of one or more of the first springs, and the push plate abuts against the connecting block.
[0024] Furthermore, the limiting component includes a housing fixed to the bottom of the docking platform, a limiting block slidably connected inside the housing along the height direction, and a triggering component for driving the limiting block to move downward.
[0025] A limiting groove is formed through the interior of the climbing plate, and the top of the limiting block slides into the interior of the limiting groove.
[0026] Furthermore, the triggering component includes a drive bar that slides inside the housing in the horizontal direction and a limiting ring that is fixedly sleeved on the outside of the drive bar;

[0029] Compared with the prior art, the emergency escape descent device provided by the present invention has the following beneficial effects:
[0030] 1. By driving the docking platform to move towards the building window sill, a passage is established that allows people to climb onto the transfer platform from the window. As the docking platform moves towards the building window sill, the distance between the column and the fence increases, and the originally bent safety rope is gradually straightened, thereby improving the safety of trapped personnel in the process of moving from the window sill to the transfer platform.
[0031] 2. When the docking platform moves to the top of the lower edge of the window sill, as the hydraulic cylinder continues to drive the docking platform to move, the limiting effect on the climbing board is automatically released. The climbing board quickly moves to the right and enters the building. Through its own weight, the climbing board rotates around the drive shaft, so that the end of the climbing board away from the docking platform rests on the ground inside the building. At this time, the trapped personnel can put their feet on the footboard and climb the climbing board to reach the docking platform. This reduces the difficulty for the trapped personnel to climb directly onto the window sill, further improves the evacuation speed of the trapped personnel, and reduces the potential risks caused by poor balance during the process of climbing onto the window sill. It also facilitates the rapid evacuation of the elderly, children and other people with mobility difficulties.
[0032] 3. Once the trapped personnel are on the transfer platform, the hydraulic control mechanism is used to move the transfer platform downwards. At this time, the inclined angle of the climbing board can be manually controlled to make contact with the ground, thus facilitating the evacuated personnel to climb down from the transfer platform.

[0042] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0043] Example: Please refer to Figure 1 - Figure 6 An emergency escape descent device includes a vehicle 1, a hydraulic lifting mechanism 2 mounted on top of the vehicle 1, and a transfer platform 3 mounted on top of the hydraulic lifting mechanism 2. The hydraulic lifting mechanism 2 is existing technology and is used to drive the transfer platform 3 to move slowly upward or downward.
[0044] Also includes:
[0045] The enclosure 28 is installed on the top of the transfer platform 3, and a walking opening 4 is provided on the outer wall of one side of the enclosure 28;
[0046] The enclosure 28 is designed to improve the safety of evacuated personnel when they are on top of the transfer platform 3, and to prevent them from falling off the transfer platform 3. The walkway 4 is designed to allow evacuated personnel to enter the inside of the enclosure 28 and to facilitate the exit of evacuated personnel inside the enclosure 28, thereby effectively improving the safety of evacuated personnel and preventing casualties during the evacuation process.
[0047] The monitoring mechanism is installed on the fence 28 and is used to monitor and direct the evacuation process. The monitoring mechanism includes an electric push rod 5 installed inside the fence 28 and a camera 6 installed at the extended end of the electric push rod 5. The camera 6 has intercom and angle adjustment functions.
[0048] On-site commanders can control the height of camera 6 by extending and retracting electric push rod 5, and control the height of transfer platform 3 through the image transmitted by camera 6, which facilitates docking with building windows. At the same time, camera 6 can be used to observe the situation of trapped personnel, which facilitates precise command and improves the speed and safety of evacuation of trapped personnel.
[0049] The docking mechanism is installed inside the transfer platform 3 to establish a connection channel between the transfer platform 3 and the building window sill. The docking mechanism includes a slide groove opened inside the transfer platform 3, multiple hydraulic cylinders 7 installed inside the slide groove, and a docking platform 8 slidably connected inside the slide groove. The extended ends of the multiple hydraulic cylinders 7 are all fixedly connected to one end of the docking platform 8. The other end of the docking platform 8 slides to the outside of the transfer platform 3.
[0050] By controlling the hydraulic lifting mechanism 2 to move the transfer platform 3 upward, the lower edge of the transfer platform 3 is not lower than the lower edge of the window of the building. Then, the hydraulic cylinder 7 is extended to move the docking platform 8 towards the window of the building, so that the docking platform 8 moves to the top of the lower edge of the window of the window, and a passage is established that can be accessed from the window to the transfer platform 3.
[0051] After the trapped personnel climb onto the transfer platform 3, they control the hydraulic cylinder 7 to retract, causing the docking platform 8 to move towards the interior of the transfer platform 3.
[0052] The protective mechanism, which is connected to the docking mechanism, is used to improve the safety of the connection channel. The protective mechanism includes two columns 9 fixed to the top of the other end of the docking platform 8 and two protective ropes 10 fixed to the top of the two columns 9 respectively. The other ends of the two protective ropes 10 are fixed to the outer wall of the enclosure 28, and the two protective ropes 10 are located on both sides of the passage 4 respectively.
[0053] As the docking platform 8 moves toward the building window sill, the distance between the column 9 and the fence 28 increases, and the originally bent protective rope 10 is gradually straightened, thereby improving the safety of the trapped personnel during the process from the window sill to the transfer platform 3.
[0054] The deployment mechanism, connected to the docking mechanism, is used to allow trapped personnel to safely and quickly board the docking mechanism. The docking platform 8 has a hollow structure, and an opening is provided at the end of the docking platform 8 away from the hydraulic cylinder 7. The deployment mechanism includes a climbing plate 11 disposed inside the docking platform 8, multiple pedals 12 mounted on the top of the climbing plate 11, a limiting component for limiting the climbing plate 11, and a driving component for driving the climbing plate 11 to move. One end of the climbing plate 11 extends to the outside of the docking platform 8. The driving component includes two fixed seats 13 respectively fixed to the inner walls on both sides of the docking platform 8, a connecting block 14 disposed between the two fixed seats 13, and multiple first springs 15 fixed to the outer wall of the docking platform 8 near the hydraulic cylinder 7. One end of each of the two fixed seats 13 extends to the outside of the docking platform 8. Movable grooves 16 are provided along the length of the outer walls on opposite sides of the two fixed seats 13. Sliding blocks 17 are slidably connected inside the two movable grooves 16. A drive shaft 18 is rotatably connected between the two sliding blocks 17. The connecting block 14 is fixedly sleeved on the outside of the drive shaft 18, and the connecting block 14 is fixedly connected to the climbing plate 11; the other end of the plurality of first springs 15 is fixedly connected to a push plate 19, the push plate 19 abuts against the connecting block 14, and the limiting assembly includes a housing 20 fixedly connected to the bottom of the docking platform 8, a limiting block 21 slidably connected inside the housing 20 along the height direction, and a triggering component for driving the limiting block 21 to move downward; a limiting groove 22 is formed through the inside of the climbing plate 11, and the top of the limiting block 21 slides to the limiting groove 22. Inside the slot 22, the triggering component includes a drive bar 23 that slides horizontally inside the housing 20 and a limiting ring 24 that is fixedly sleeved on the outside of the drive bar 23. The limiting ring 24 is located inside the housing 20 and is used to limit the drive bar 23. The limiting block 21 has an inclined groove 25 and a through groove 26 inside, and the inclined groove 25 and the through groove 26 are connected to each other. A second spring 27 is fixedly connected to the bottom of the limiting block 21, and the bottom end of the second spring 27 is fixedly connected to the inner wall of the bottom of the housing 20.
[0055] When the docking platform 8 moves to the top of the lower edge of the window sill, as the hydraulic cylinder 7 continues to drive the docking platform 8 to move, the drive bar 23 begins to abut against the wall below the window sill. The drive bar 23 then moves into the housing 20. Through the action of one end of the drive bar 23 abutting against the inclined groove 25, the drive limiting block 21 slides downward. At this time, the second spring 27 is compressed. When the drive bar 23 enters the through groove 26, the limiting block 21 completely disengages from the limiting groove 22. After the climbing plate 11 loses its limiting effect, through the rebound force of the first spring 15, in conjunction with the push plate 19 and the connecting block 14, the climbing plate 11 is driven to move quickly to the right and enter the building. During this process, the slider 17 moves accordingly. The connecting block 14 and the climbing plate 11 are completely separated from the docking platform 8 at this time. The climbing plate 11 rotates around the drive shaft 18 by its own weight, so that the end of the climbing plate 11 away from the docking platform 8 rests on the ground inside the building. At this time, the trapped personnel can put their feet on the footboard 12 and climb the climbing plate 11 to reach the docking platform 8. This reduces the difficulty for the trapped personnel to climb directly onto the windowsill, further improves the evacuation speed of the trapped personnel, and reduces the potential risks caused by poor balance during the process of climbing onto the windowsill. It also facilitates the evacuation of the elderly, children and other people with mobility difficulties.
[0056] In addition, after the trapped personnel climb onto the transfer platform 3, the hydraulic cylinder 7 is controlled to retract, which drives the docking platform 8 to move and reset towards the inside of the transfer platform 3. Then, the hydraulic control mechanism 2 is controlled to drive the transfer platform 3 to move downward. At this time, the climbing board 11 can be manually controlled to tilt and contact the ground, so that the evacuated personnel can climb down from the transfer platform 3 through the climbing board 11.
[0057] Working principle: During use, the commander controls the vehicle 1 to move to the ground on the side of the window where the trapped personnel are waiting, and controls the lateral distance between the vehicle 1 and the window. Due to obstacles such as flower beds and green plants at the bottom of some buildings, the transfer platform 3 cannot directly reach the window and there is still a certain distance. At this time, the hydraulic lifting mechanism 2 is first controlled to move the transfer platform 3 upward, so that the lower edge of the transfer platform 3 is not lower than the lower edge of the window sill of the building. Then, the hydraulic cylinder 7 is controlled to extend, driving the docking platform 8 towards the window sill of the building, so that the docking platform 8 moves to the window sill. At the top of the lower edge, a passageway is established for access to the transfer platform 3 via the window. As the docking platform 8 moves towards the building window sill, the distance between the column 9 and the barrier 28 increases, and the originally bent safety rope 10 is gradually straightened, thereby improving the safety of trapped personnel during the process from the window sill to the transfer platform 3. When the docking platform 8 moves to the top of the lower edge of the window sill, as the hydraulic cylinder 7 continues to drive the docking platform 8 to move, the drive bar 23 begins to abut against the wall below the window sill. The drive bar 23 then moves into the housing 20. One end of the limit block 21 slides downwards due to its contact with the inclined groove 25. At this time, the second spring 27 is compressed. When the drive bar 23 enters the through groove 26, the limit block 21 completely disengages from the inside of the limit groove 22. After the climbing plate 11 loses its limiting function, it is driven by the rebound force of the first spring 15, in conjunction with the push plate 19 and the connecting block 14, to move the climbing plate 11 quickly to the right and into the building. During this process, the slider 17 slides synchronously to the right along the inner wall of the movable groove 16 to the rightmost side of the movable groove 16. At this time, the connecting block 14 and the climbing plate 11 are completely separated. Completely detached from the docking platform 8, the climbing board 11 rotates around the drive shaft 18 under its own weight, causing the end of the climbing board 11 away from the docking platform 8 to rest on the ground inside the building. At this time, the trapped personnel can place their feet on the footboard 12 and climb the climbing board 11 to reach the docking platform 8. This reduces the difficulty for the trapped personnel to climb directly onto the windowsill, further increases the speed of evacuation, and reduces the potential risks caused by poor balance during the process of climbing onto the windowsill. It also facilitates the evacuation of elderly people, children, and other people with mobility difficulties.
