[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When the present invention is used, the direct push mechanism in the device plays a role in pushing the horizontal channel mechanism to rise to a high place, and after the device is unfolded, the escape cloth bags stretched at the front and back will relax and form a Z-shaped channel inside. At this time, the telescopic cloth bag, the escape channel and the escape cloth bag constitute a channel for escape.

At this time, the second rotating block at the top of the large oil cylinder will rotate inside the second rotating seat at the bottom of the second connecting plate, and the first rotating block at the bottom will rotate inside the first rotating seat at the top of the first connecting plate. Moreover, since the outer connecting rod and the inner connecting rod form a scissor frame structure, the scissor frame structure composed of the outer connecting rod and the inner connecting rod will gradually unfold when the large oil cylinder is extended, and the end will vertically thrust the first direct push column through the cooperation of the first rotating pin, thereby playing an auxiliary lifting effect, ensuring that the device can have a higher bearing capacity, thereby stably driving the transverse channel mechanism to be lifted to the required height, and ensuring the reliability of the escape device.

When the transmission belt rotates, it cooperates with the connecting strip, the connecting rope and the slip ring to drive the telescopic bag to contract and extend. When the telescopic bag is in a contracted state, the wind resistance of the device during the lifting process is reduced, and the stability during lifting is improved. When the telescopic bag is extended, the lateral distance of the escape passage is increased. The design structure is simple, so that the device can be kept at a certain distance from the fire scene for escape, thereby improving the high-rise escape effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In this embodiment, the two base frames 1 in the device are fixed on the transport vehicle for use with the transport vehicle, and the reinforced steel cables 4 and the escape cloth bags 41 in the device are in a relaxed state when the device is in the storage state. When a fire occurs in a high-rise building and the device needs to be used for rescue and escape, the device is moved outside the fire range of the high-rise building by the transport vehicle, and then all the small cylinders 204 are controlled by the controller to start and extend. When the small cylinders 204 are started, an upward thrust is generated, and the second straight push column 202 inserted into the first straight push column 201 is pushed upward. When the second straight push column 202 is pushed upward, the first straight push column 201 above it will move upward synchronously and use the small cylinders 204 inside to push the second straight push column 202 inside. Under the cooperation of each other, the device is geometrically The multiple increases, during this process, the straight-pushing mechanism 2 on the rear side will move toward the front side. At this time, the escape cloth bag 41 that is tightened at the front and back will become loose, the internal space will increase, and a Z-shaped channel will be formed. When the straight-pushing mechanism 2 raises the horizontal channel mechanism 5 to the floor height where people gather in the high-rise, the people can enter the horizontal telescopic cloth bag 513 from the window and then safely enter the escape channel 502 and then enter from the top of the Z-shaped escape cloth bag 41, and finally escape from the bottom of the escape cloth bag 41 to the ground.

The channel composed of the telescopic cloth bag 513, the escape channel 502 and the escape cloth bag 41 has good airtightness, which reduces the risk of rescuing people who are afraid of heights and the elderly and weak, and has a high safety factor.

[0031] Embodiment 2: Figure 1-Figure 7 As shown, a rotating frame 507 is fixedly connected to the top of the escape passage 502 near the middle position, a second belt roller 508 is rotatably connected between the front and rear inner surface walls of the rotating frame 507, a third connecting plate 505 extending upward is fixedly connected between the ends of the two cross bars 503, a first belt roller 506 is rotatably connected between the inner surface walls of the third connecting plate 505, and the first belt roller 506 and the second belt roller 508 are located at the same height, a motor 509 is installed on the front surface of the rotating frame 507, and the output end of the motor 509 rotates through the rotating frame 507. The front surface extends to the rear side, the output end of the motor 509 is fixedly connected to the front end of the second belt roller 508, two sets of transmission belts 510 are sleeved between the outer surfaces of the first belt roller 506 and the second belt roller 508, and a connecting rope 511 is connected between the tops of multiple slip rings 504 sleeved on the outside of the same cross bar 503, one end of the connecting rope 511 is fixedly connected to the outer surface of the escape passage 502, and the other end of the connecting rope 511 is fixedly connected to a connecting strip 512, and the top of the connecting strip 512 is fixedly connected to the outer surface of the transmission belt 510 near the bottom.

[0032] In this embodiment, when in use, the motor 509 in the device will drive the second belt roller 508 inside the rotating frame 507 to rotate. When the second belt roller 508 rotates, it cooperates with the first belt roller 506 to drive the transmission belt 510 to rotate. When the transmission belt 510 rotates counterclockwise, it will drive the left end of the connecting rope 511 to move to the right through the connecting strip 512. At this time, the connecting rope 511 will drive multiple slip rings 504 to slide to the left on the surface of the cross bar 503. When all the slip rings 504 are folded, they will drive the telescopic cloth bag 513 contracts. When the transmission belt 510 rotates clockwise, the connecting rope 511 will drive the left and right slip rings 504 to move to the left in sequence. Since the right end of the connecting rope 511 is connected to the escape passage 502, the left end of the connecting rope 511 will be in a taut state after moving to a certain distance, and all the slip rings 504 will be reset. At this time, the telescopic cloth bag 513 is in an extended state, which increases the lateral distance of the escape passage 502. The design mechanism is simple, so that the device can be kept at a certain distance from the fire scene for escape, thereby improving the high-rise escape effect.

[0033] Embodiment 3: Figure 1-Figure 7 As shown, the auxiliary lifting mechanism 3 is composed of a plurality of outer connecting rods 301, an inner connecting rod 302, a first connecting plate 304 and a second connecting plate 307. The outer connecting rod 301 and the inner connecting rod 302 are rotatably connected at the center with a second rotating pin 303. The first connecting plate 304 is fixedly connected between the bottoms of the two outer connecting rods 301 at the same height. The second connecting plate 307 is fixedly connected between the tops of the two outer connecting rods 301 at the same height. The first connecting plate 304 and the second connecting plate 307 are staggered up and down. The top center of the first connecting plate 304 is fixedly connected with a first rotating seat 30 5. The first rotating block 306 is rotatably connected between the inner surface walls of the first rotating seat 305, the second rotating seat 308 is fixedly connected at the bottom center of the second connecting plate 307, the second rotating block 309 is rotatably connected between the inner surface walls of the second rotating seat 308, a large oil cylinder 310 is fixedly installed between the outer surfaces of the opposite sides of the first rotating block 306 and the second rotating block 309, the outer surfaces of the plurality of first straight push columns 201 are fixedly connected with the first rotating pin 203 near the bottom, and both ends of the outer connecting rod 301 and the inner connecting rod 302 are rotatably connected to the first rotating pin 203.

[0034] In this embodiment, when the direct push mechanism 2 pushes the transverse channel mechanism 5 to rise, the large oil cylinder 310 can be started synchronously. At this time, the second rotating block 309 at the top of the large oil cylinder 310 will rotate inside the second rotating seat 308 at the bottom of the second connecting plate 307, and the first rotating block 306 at the bottom will rotate inside the first rotating seat 305 at the top of the first connecting plate 304. And because the outer connecting rod 301 and the inner connecting rod 302 form a scissor frame structure, the scissor frame structure composed of the outer connecting rod 301 and the inner connecting rod 302 will gradually unfold when the large oil cylinder 310 is extended, and the end will vertically push the first direct push column 201 through the cooperation of the first rotating pin 203, thereby playing an auxiliary lifting effect, ensuring that the device can have a higher bearing capacity, thereby stably driving the transverse channel mechanism 5 to be lifted to the required height, ensuring the reliability of the escape device.

[0035] The effect and working principle achieved by the entire mechanism are as follows: when a fire occurs in a high-rise building and the device needs to be used for rescue and escape, the device is moved outside the fire range of the high-rise building by a transport vehicle, and then all the small cylinders 204 are controlled by the controller to start and extend. When the small cylinders 204 are started, an upward thrust is generated, and the second straight push column 202 inserted into the first straight push column 201 is pushed upward. When the second straight push column 202 is pushed upward, the first straight push column 201 above it will move upward synchronously and use the small cylinders 204 inside to push the second straight push column 202 inside. Under the cooperation of each other, the device increases geometrically. During this process, the straight push mechanism 2 on the rear side will move forward sideways. When the escape bag 41 is pulled tight at the front and back, it will become loose, the internal space will increase, and a Z-shaped channel will be formed. When the direct-pushing mechanism 2 raises the transverse channel mechanism 5 to the height where people gather in the high-rise, the people can enter the transverse telescopic bag 513 from the window, then safely enter the escape channel 502, and then enter from the top of the Z-shaped escape bag 41, and finally escape from the bottom of the escape bag 41 to the ground. The structure of the device is simple and reliable, and can effectively cope with high-rise escape situations. The channel composed of the telescopic bag 513, the escape channel 502 and the escape bag 41 has good airtightness, which reduces the risk of rescuing people who are afraid of heights and the elderly and weak, and has a high safety factor.

[0036] In addition, when the direct push mechanism 2 pushes the transverse channel mechanism 5 to rise, the large oil cylinder 310 can be started synchronously. At this time, the second rotating block 309 at the top of the large oil cylinder 310 will rotate inside the second rotating seat 308 at the bottom of the second connecting plate 307, and the first rotating block 306 at the bottom will rotate inside the first rotating seat 305 at the top of the first connecting plate 304. Since the outer connecting rod 301 and the inner connecting rod 302 form a scissor frame structure, the scissor frame structure composed of the outer connecting rod 301 and the inner connecting rod 302 will gradually unfold when the large oil cylinder 310 is extended, and the end will vertically push the first direct push column 201 through the cooperation of the first rotating pin 203, thereby playing an auxiliary lifting effect, ensuring that the device can have a higher bearing capacity, thereby stably driving the transverse channel mechanism 5 to be lifted to the required height, ensuring the reliability of the escape device.

[0037] When the second belt roller 508 rotates, it cooperates with the first belt roller 506 to drive the transmission belt 510 to rotate. When the transmission belt 510 rotates counterclockwise, it drives the left end of the connecting rope 511 to move to the right through the connecting strip 512. At this time, the connecting rope 511 drives multiple slip rings 504 to slide to the left on the surface of the cross bar 503. When all the slip rings 504 are retracted, the telescopic cloth bag 513 will shrink. When the transmission belt 510 rotates clockwise, the connecting rope 511 drives the left and right slip rings 504 to move to the left in turn. When the connecting rope 511 is in a taut state, all the slip rings 504 are reset. At this time, the telescopic cloth bag 513 is in an extended state, which increases the lateral distance of the escape passage 502. The design structure is simple, so that the device can be kept at a certain distance from the fire scene for escape, thereby improving the high-rise escape effect.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
