Description

Technical Field

[0001] The invention relates to the technical field of escape devices, in particular to a high-rise escape device. Background Art

[0002] The principle of today's high-rise escape devices is the climbing rope principle. The basic structure is a sufficiently long rope and a metal object. The rope is wrapped around the metal object layer by layer (without a knot), and the metal object is buckled with the buttons on the human body. The user only needs to use a small force to pull the rope to generate a certain friction force, and then the friction force is increased by a certain multiple by wrapping the rope around the metal object, so that a relatively large friction force can be generated between the rope and the metal object with a small force. When the friction force is greater than the weight of the human body, it will have the effect of staying in the air. Most of these similar products require professional operation, and they belong to the "instant stop type". Once force is applied, they stop immediately, which may cause secondary injuries to those who are helping the elderly escape, and The multiple of the friction increase between the rope and the metal object has been set and cannot be changed. If the magnification is small, a heavier user or multiple people will need more strength to stay in the air when descending; if the original setting is large, a lighter person may pull the rope slightly when descending, which will generate a particularly large friction force, and the instantaneous acceleration will be very large, which may cause harm to the human body. Moreover, if it is a rainy day or other special circumstances, it will affect the magnification factor. Therefore, we need a solution to the above problem, which can generate suitable friction according to the weight of different people, and can adjust the device to a certain extent through manual adjustment, so that the magnification factor of the device can be adjusted, thereby adjusting the final friction force. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a high-rise escape device, which adjusts the gravity pressure device and the brake pressure device according to the different weights of people so that the main rope is subjected to different degrees of pressure, which can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-rise escape device, comprising a columnar main body system, a left handle assembly, a gravity system, a right handle assembly and a life-saving suit system, wherein the left side of the columnar main body system is provided with a left handle assembly, and the gear assembly in the left handle assembly is meshed with a rotatable adjustable gear in the columnar main body system, the right side of the columnar main body system is provided with a right handle assembly, and the right handle assembly is connected to a connecting column in the columnar main body system through a connecting block, a gravity system is provided at the lower end of the columnar main body system, a life-saving suit system is provided at the lower end of the gravity system, and the life-saving suit system is connected to a gravity main cylinder in the gravity system through a safety rope, and the outer surfaces of various components of the columnar main body system, the left handle assembly, the gravity system, the right handle system and the life-saving suit system are provided with a fire-resistant layer.

[0005] Furthermore, the columnar main body system includes a connecting column, and circular holes are provided on the upper and lower ends of the upper surface and the outer side surface of the connecting column. The outer surface of the connecting column is provided with a fixed disk, a rotatable adjustable gear and a gravity pressure device from top to bottom. The fixed disk and the rotatable adjustable gear are both provided with circular holes. A main rope is provided on the outer side surface of the connecting column, and the main rope forms a spiral structure on the outer surface of the connecting column through the circular holes on the connecting column, the circular holes on the fixed disk and the circular holes on the rotatable adjustable gear. A rope roll is provided at the lower end of the main rope, and the friction force is changed by the winding of the main rope with the connecting column.

[0006] Furthermore, the left handle assembly includes a left handle, which is a U-shaped structure. The right end of the left handle is connected to an adjustment track, and the adjustment track is connected to a gear assembly. A gear meshing with the gear assembly is provided on the right side of the adjustment track. The left handle assembly is connected to a gravity sub-cylinder in a gravity system through a connecting block. By pulling the left handle downward, the adjustment track drives the gear assembly to rotate, and the pinion in the gear assembly meshes with a rotatable adjustable gear in the columnar main body system. When the rotatable adjustable gear rotates, the number of windings between the main rope and the connecting column increases, thereby increasing the friction force.

[0007] Furthermore, the gravity system includes a secondary rope, the left end of which is connected to the gravity pressure device in the columnar main body system, the outer surface of the secondary rope is provided with a rope shell, the lower end of the rope shell is provided with a gravity auxiliary cylinder, the side of the gravity auxiliary cylinder is connected to the gravity track, and the left side of the gravity auxiliary cylinder is connected to the gravity main cylinder.

[0008] Furthermore, a gravity spring is provided in the gravity main cylinder, the lower end of the gravity spring is connected to piston one, the ear plate on the right side of piston one is connected to the ear plate on the left side of piston two, and a gravity spring is provided on the upper surface of piston two, and the connecting column at the lower end of piston two is connected to the clamping seat on the inner side of the gravity track. According to the different weights of the human body, piston one drives piston two to move downward, and during the downward movement of piston two, a tightening force is applied to the secondary rope. During the tightening of the secondary rope, the pressure device is squeezed, thereby generating a friction force suitable for the escapee during the descent.

[0009] Further, the right handle assembly includes a right handle. The right handle has an L-shaped structure. Opposite-sex magnets that attract each other are provided at the bent hook of the L-shaped structure of the right handle. The outer side of the opposite-sex magnet is connected to a handle lever. A three-headed rope is provided at the left end of the handle lever. The left end of the three-headed rope is connected to a buffer assembly with a buffer spring inside through an outer rope housing. A braking pressure device is provided at the lower end of the buffer assembly, and the braking pressure device is connected to a connecting column in the cylindrical main body system through a connecting plate. The three-headed rope is connected to a card positioner assembly through the outer rope housing. By pressing the right side of the handle lever to generate an outward pulling force on the three-headed rope, a pulling force is simultaneously applied to both the left and right ends of the three-headed rope. The left end of the three-headed rope squeezes the braking pressure device, so that the rope reel does not release the rope due to excessive pressure, keeping the escapee in a suspended state. At the same time, the right end of the three-headed rope causes the card positioner to disengage from the gravity track through the pulling force. At this time, the gravity track can move up and down freely, so that the frictional force generated by the gravity pressure device can be adjusted arbitrarily. Similarly, when the handle lever is released, due to the attraction to the opposite-sex magnet, the handle lever returns to its original position, so that the left and right ends of the three-headed rope return to their original positions.

[0010] Further, the card positioner assembly includes a card positioner. The card positioner includes a card position plate and a semi-circular card position seat. The card position plate of the card positioner is located inside the semi-circular card position seat, so that the card positioner can only rotate clockwise. The card position plate in the card positioner fits with the gravity track. When the gravity track rotates upward to generate a large frictional force by the gravity pressure device, the card positioner is not affected. However, when the escape device descends too fast and the person is in a weightless state, since the card positioner can only rotate clockwise, the card positioner has a fixed limiting effect on the gravity track, so that the frictional force generated by the gravity pressure device will not decrease due to weightlessness. The outside of the card positioner is connected to a buffer through a connecting plate. The buffer has a hollow cylindrical structure, and a buffer spring is provided inside the buffer. The buffer spring has a function of returning the three-headed rope to its original position.

[0011] Further, the life jacket system includes a safety rope. The lower end of the safety rope is connected to the life jacket. The life jacket has a hollow structure. Circular ventilation slots are provided at the front end and the left and right sides of the life jacket shell. The circular ventilation slots of the life jacket place the user's head and arms outside, so that the user can observe the external situation and control the device.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The high-rise escape device of the present invention has the following advantages:

[0013] 1. The left handle assembly is provided on the present invention. By pulling down the left handle, the gear assembly drives the rotatable adjustment gear, thereby changing the number of turns of the main rope around the connecting column, and thus changing the first frictional force during the descent of the escape device.

[0014] 2. The present invention is provided with a gravity system. Through the action of human body gravity, piston one drives piston two to move downward, so that piston two pulls the gravity spring so that the secondary rope has a downward pulling force. The secondary rope squeezes the gravity pressure device through the downward pulling force. According to the different weights of the escapees, the spring has different downward forces, so that the gravity pressure device is squeezed to different degrees, thereby generating a suitable friction force for the escapees.

[0015] 3. The present invention is provided with a right handle assembly, and the pulling force of the handle lever on the three-head rope causes the left side of the three-head rope to exert pressure on the brake pressure device, thereby increasing the friction and resistance of the rope during the process of releasing the rope, slowing down the winding speed of the main rope on the connecting column, controlling the size of the friction between the main rope and the connecting column, and the positioning device on the right side of the three-head rope has a limiting effect on the gravity track, which has a control effect on the user in a weightless state, and has a control effect on the friction generated by the different weights of the human body on the secondary rope.

The fixed disc 8 and the rotatable adjustable gear 9 are provided with circular holes. The outer side of the connecting column 7 is provided with a main rope 6, and the main rope 6 forms a spiral structure on the outer surface of the connecting column 7 through the circular holes on the connecting column 7, the circular holes on the fixed disc 8 and the circular holes on the rotatable adjustable gear 9. The lower end of the main rope 6 is provided with a rope reel 11, and the friction force is changed by winding the main rope 6 with the connecting column 7. The left handle assembly 2 includes a left handle 12, and the left handle 12 is a U-shaped structure. The right end of 12 is connected to the adjustment track 14, the adjustment track 14 is connected to the gear assembly 13, and the right side of the adjustment track 14 is provided with a gear meshing with the gear assembly 13. The left handle assembly 2 is connected to the gravity sub-tube 18 in the gravity system 3 through the connecting block. By pulling the left handle 12 downward, the adjustment track 14 drives the gear assembly 13 to rotate, and the small gear in the gear assembly 13 is meshed with the rotatable adjustable gear 9 in the columnar main body system 1, so that when the rotatable adjustable gear 9 rotates, the number of winding circles between the main rope 6 and the connecting column 7 increases, thereby increasing the friction force. The gravity system 3 includes a secondary rope 15, the left end of the secondary rope 15 is connected to the gravity pressure device 10 in the columnar main body system 1, and the outer surface of the secondary rope 15 is provided with a rope shell 16, and the lower end of the rope shell 16 is provided with a There is a gravity sub-cylinder 18, the side of the gravity sub-cylinder 18 is connected to the gravity track 19, the left side of the gravity sub-cylinder 18 is connected to the gravity main cylinder 17, a gravity spring 20 is arranged in the gravity main cylinder 17, the lower end of the gravity spring 20 is connected to the piston 1 21, the ear plate on the right side of the piston 1 21 is connected to the ear plate on the left side of the piston 2 22, and the upper surface of the piston 2 22 is provided with a gravity spring 20, the connecting column at the lower end of the piston 2 22 is connected to the clamping seat on the inner side of the gravity track 19, according to the different weights of the human body, the piston 1 21 drives the piston 2 22 to move downward, and the piston 2 22 exerts a tightening force on the secondary rope 15 during the downward movement, and the pressure device 10 is squeezed during the tightening of the secondary rope 15, thereby generating a friction force suitable for the escapee's descent process, and the right handle assembly 4 includes a right handle 23.The right handle 23 is in an L-shaped structure. The bent part of the L-shaped structure of the right handle 23 is connected to the异性 magnet 24. The outer side of the异性 magnet 24 is connected to the handle lever 25. At the left end of the handle lever 25, there is a three-headed rope 29. The left end of the three-headed rope 29 is connected to a buffer assembly 26 with a buffer spring inside through an outer rope shell. At the lower end of the buffer assembly 26, there is a braking pressure device 27, and the braking pressure device 27 is connected to the connecting column 7 in the cylindrical main body system 1 through a connecting plate. The three-headed rope 29 is connected to a clamping device assembly 28 through an outer rope shell, pressing the right side of the handle lever 25 to give the three-headed rope 29 an outward pulling force, so that both the left and right ends of the three-headed rope 29 have a pulling force at the same time. The left end of the three-headed rope 29 squeezes the braking pressure device 27, so that the rope reel 11 does not release the rope due to excessive pressure, making the escapee in a suspended state. At the same time, the right end of the three-headed rope 29 makes the clamping device 30 disengage from the gravity track 19 through the pulling force. At this time, the gravity track 19 can move up and down freely, so that the frictional force generated by the gravity pressure device 10 can be adjusted arbitrarily. Similarly, when the handle lever 25 is released, due to the attraction to the异性 magnet 24, the handle lever 25 returns to its original position, so that the left and right ends of the three-headed rope 29 return to their original positions. The clamping device assembly 28 includes a clamping device 29. The clamping device 30 includes a clamping plate and a semi-circular clamping seat, and the clamping plate of the clamping device 30 is located inside the semi-circular clamping seat, so that the clamping device 30 can only rotate clockwise, and the clamping plate in the clamping device 30 fits with the gravity track 19. When the gravity track 19 rotates upward to make the gravity pressure device 10 generate a large frictional force, the clamping device 30 is not affected by it. But when the escape device descends too fast and the person is in a weightless state, because the clamping device 30 can only rotate clockwise, the clamping device 30 has a fixed limiting effect on the gravity track 19, so that the frictional force generated by the gravity pressure device 10 will not decrease due to weightlessness. The outside of the clamping device 30 is connected to a buffer 31 through a connecting plate. The buffer 31 is a hollow cylindrical structure, and there is a buffer spring inside the buffer 31. The buffer spring has a function of returning the three-headed rope 29 to its original position. The life jacket system 5 includes a safety rope 32. The lower end of the safety rope 32 is connected to the life jacket 33. The life jacket 33 is a hollow structure, and circular ventilation slots are provided at the front end and the left and right sides of the shell of the life jacket 33. The circular ventilation slots of the life jacket 33 place the user's head and arms outside, so that the user can observe the external situation and control the device.,

[0027] When in use:

[0028] It should be noted that the term "异性磁铁" in the original text is not a standard and common term. It may need to be further clarified according to the actual situation to ensure the accuracy of the translation. If it is a specific type of magnet with a specific name, it should be translated accurately.Initially, the left handle 12 is placed at the uppermost end of the adjustment track 14, so that the number of windings of the main rope 6 and the connecting column 7 is set to the minimum. The escapee puts on the immersion suit 33, and the escapee places his head and arms outside the immersion suit through the circular slots of the immersion suit 33, so as to observe the external environment and the slot escape device. At the same time, the escapee holds the handle 23 with his right hand and presses the handle lever 25 inward, so that the three-head rope 29 generates a pulling force. At this time, the left end of the three-head rope 29 tightens the brake pressure device 27, increasing the friction force, so that the rope reel 11 is pulled by the friction force. The large friction makes it impossible to release the rope. At this time, the escapee is in a suspended state. When the escapee is fully dressed, due to the escapee's own gravity, the piston 1 21 drives the piston 2 22 to have a downward force, and the piston 22 causes the secondary rope 15 to produce a compression effect on the gravity pressure device 10, and the gravity spring 20 produces different downward pulling forces according to the different weights of the escapee, so that the pulling force on the gravity pressure device 10 is different, thereby generating a friction force more suitable for the escapee. At this time, the handle lever 25 is loosened, and the handle is used to release the rope. The attraction between the lever 25 and the opposite magnet 24 causes the handle lever 25 to automatically return to its original position. At the same time, the returned handle lever 25 causes the three-head rope 29 to return to its original position. At this time, the positioner assembly 29 on the right side of the three-head rope 29 is separated from the gravity track 19 in the gravity system 3, so that the gravity track 19 can move up and down freely, thereby arbitrarily adjusting the size of the friction force produced by the gravity pressure device 10, and when the weightlessness caused by excessive speed during the accelerated descent is caused, the positioner assembly 29 can only rotate clockwise, thereby avoiding the problem of weightlessness caused by excessive speed. When the gravity track 19 moves downward and the friction force generated by the gravity pressure device 10 is reduced, the positioner assembly 29 has a positioning and fixing effect on the gravity track 19. When the handle lever 25 is released, the brake pressure device 27 has no pressure on the rope, and the rope reel 11 releases the rope, allowing the escapee to descend from a height. At the same time, the left handle 12 is pulled down to increase the number of windings of the main rope 6 and the connecting column 7, thereby increasing the friction force of the main rope 6 on the connecting column 7, thereby controlling the speed of the escapee during the descent, allowing the escapee to escape at a suitable speed.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
