Description

Technical Field

[0001] This invention relates to the field of escape equipment, and in particular to a high-altitude escape device. Background Technology

[0002] With urban development, high-rise buildings are increasing in number and height. In the event of a fire, people on higher floors cannot escape via staircases and are trapped in their original apartments or forced to go to the rooftop. Ground firefighters cannot rescue them via staircases, so the trapped people must rely on themselves to save themselves. The safest way to get from a high-rise to the ground is to use steel cables to lower people to the ground.

[0003] Some existing escape devices, such as the patent document disclosed in application number 201410305603.2, can be raised and lowered using steel wire ropes. This document uses the lever principle to control the brake, but due to the limited space, the distance between the lever fulcrum and the rope cannot be increased. Therefore, more force is required to use it, which is inconvenient or impossible for people with less strength to use. To address this issue, we provide a high-altitude escape device to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-altitude escape device.

[0011] Preferably, a locking device is provided on the top surface of the left or right housing. The locking device includes a locking outer shell with a slit fixedly installed on the top surface of the left or right housing. Locking blocks are fixedly installed on both side walls of the locking outer shell. A rotating rod is rotatably installed on the side wall of the locking outer shell. A curved rod located inside the locking outer shell is connected to the end of the rotating rod. A transmission rod is provided on the curved rod. A positioning pin is fixedly installed on the top surface of the transmission rod. A guide tube is fixedly installed on the top wall of the inner lock outer shell. A meniscus is rotatably installed on the upper surface of the locking outer shell. A limiting hole adapted to the positioning pin is opened on the upper surface of the meniscus. A torsion spring is sleeved on the outer surface of the rotating shaft of the meniscus located inside the locking outer shell.

[0012] Preferably, a disassembly device is provided between the two self-locking anti-fall devices. The disassembly device includes a first latching plate and a second latching plate disposed on the inner wall of the self-locking housing. A first latching block is fixedly connected to the side of the first latching plate near the second latching plate. A second latching block adapted to the first latching block is fixedly disposed on the side wall of the second latching plate near the first latching plate.

[0013] Preferably, the self-locking groove is inclinedly arranged on the self-locking plate, and the distances between the top and bottom ends of the self-locking groove and the side wall of the self-locking plate are a and b, respectively, then a < b.

[0015] Preferably, a waist belt is fixedly installed on the front of the left or right shell.

[0016] The present invention has the following advantages:

[0017] 1. This invention converts the pressing pressure from the button handle into pneumatic force through a pneumatic component, and then converts the pneumatic force into a force to release the self-locking anti-fall device through a transmission component. Thus, it does not directly apply the pulling force to the self-locking anti-fall device. Compared with the existing schemes that directly apply the pulling force to the self-locking anti-fall device, the scheme adopted by this invention is more labor-saving and can release the locking state with a smaller force.

[0018] 2. The present invention uses two adjacent self-locking grooves to bring the second roller group located therein closer to each other, thereby clamping the wire rope located between the two second roller groups. Due to gravity, the greater the downward force, the greater the clamping force on the wire rope between the two second roller groups, thereby achieving self-locking and preventing falling.

[0019] 3. The present invention applies force to the power rod, which drives the second connecting rod to move through the first pull rod and the sliding frame, thereby driving the second roller group to move. The second roller group slides downward in the self-locking groove. Since the self-locking groove is inclined, the distance between two adjacent second roller groups increases, and the wire rope is no longer clamped, thereby releasing the locking state.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0041] like Figure 1 The embodiment shown in —18,

[0042] A high-altitude escape device includes an outer shell comprising a left shell 11 and a right shell 12. A button handle 2 is fixedly installed on one side of the outer surface of both the left and right shells 11 and 12, and a footplate 4 is fixedly installed on the bottom of each. A fixing rod 6 is fixedly installed inside both the left and right shells 11 and 12. A self-locking fall arresting device 7 is fixedly installed on one side of each fixing rod 6. A pneumatic device 8 is provided on the other side of the fixing rod 6 in the left and / or right shells 12. The pneumatic device 8 includes a pneumatic component 81 and a transmission component 82. The transmission component 82 is connected to the pneumatic component 81 via a brake rope. The button handle 2 transmits gripping force to the pneumatic component 81, converting it into pneumatic pressure, which is then transmitted to the transmission component 82, thereby transmitting power to the self-locking fall arresting device 7.

[0043] The pressing force from the button handle 2 is converted into pneumatic force by the pneumatic component 81, and then the pneumatic force of the pneumatic component 81 is converted into the force to release the self-locking anti-fall device 7 by the transmission component 82. Therefore, it is not necessary to directly apply the pulling force to the self-locking anti-fall device 7. Compared with the existing schemes that directly apply the pulling force to the self-locking anti-fall device 7, the scheme adopted by the present invention is more labor-saving and can release the locking state with a smaller force.

[0044] When in use, for example, when climbing upwards, only the right foot needs to move the right shell 12 upwards. At this time, the person's center of gravity is on the left foot, and the self-locking fall arresting device 7 in the left shell 11 is in a locked state. The self-locking fall arresting device 7 in the right shell 12 is unlocked due to the upward movement. When the left foot needs to climb upwards, the person's center of gravity is on the right foot, and the right foot applies a downward force to the self-locking fall arresting device 7 in the right shell 12, thereby locking the self-locking fall arresting device 7 in the right shell 12. The left foot moves the left shell 11 and the self-locking fall arresting device 7 in it upwards. At this time, the self-locking fall arresting device 7 in the left shell 11 is in an unlocked state. After climbing, the self-locking fall arresting device 7 in the left shell 11 is locked by a downward force. That is, when climbing, it can move upwards but cannot move downwards, thus achieving self-locking fall arrest under the action of gravity.

[0045] The pneumatic assembly 81 includes a pneumatic housing 811 mounted on the side wall of the fixed rod 6. A mounting block 812 is fixedly installed inside the pneumatic housing 811. Two sliders 819 are slidably arranged left and right inside the mounting block 812, and a lifting plate 813 is slidably arranged up and down inside the mounting block 812. An active rod 815 is fixedly installed on the top surface of the lifting plate 813. A clamping plate 816 is fixedly connected to the bottom surface of each slider 819. An active airbag 818 is arranged between the two clamping plates 816. Inclined grooves 814 are opened through both ends of the side of the lifting plate 813. A sliding rod 817 is slidably arranged inside each inclined groove 814, and the sliding rod 817 is rotatably connected to the slider 819.

[0046] See Figure 9 and Figure 10 In this embodiment, the pneumatic device 8 can be divided into two, which are respectively installed on two fixed rods 6. That is, each pneumatic device 8 corresponds to a button handle 2 and a self-locking anti-fall device 7. When in use, the button handle 2 is pressed to transmit power to the active rod 815. The active rod 815 drives the lifting plate 813 to move downward in the mounting block 812, thereby causing the two sliding rods 817 to slide in the two inclined grooves 814. This causes the two sliders 819 to drive the clamping plates 816 connected to them to move closer to each other, flattening the active airbag 818 located between the two clamping plates 816 and forcing the gas inside out from the outlet to the transmission assembly 82. Through the mutual transmission of the above-mentioned components, the gripping force of the button handle 2 is converted into the pressure of the gas output by the active airbag 818.

[0047] The transmission assembly 82 includes a transmission housing 821 mounted on the side wall of the fixed rod 6. A driven airbag 822 is disposed inside the transmission housing 821. A transmission plate 823 is hinged to the top surface of the transmission housing 821, and one end of the transmission plate 823 is located inside the transmission housing 821. An unlocking rod 824 is also hinged to the top surface of the transmission housing 821. The other end of the transmission plate 823 is hinged to the end of the unlocking rod 824. The other end of the unlocking rod 824 is connected to the self-locking anti-fall device 7 through a brake rope.

[0048] See Figure 9 and Figure 11 In this embodiment, the transmission plate 823 is shaped like a "7". High-pressure gas from the active airbag 818 is transmitted to the driven airbag 822 through the air pipe. The driven airbag 822 expands due to the gas from the active airbag 818, which in turn causes the transmission plate 823 located in the transmission housing 821 to move. This causes the transmission plate 823 to rotate about the rotation axis, causing one end of the unlocking rod 824 to rotate downward with the transmission plate 823. The other end of the unlocking rod 824 will drive the brake rope connected to the self-locking anti-fall device 7 to move upward, thereby releasing the self-locking anti-fall device 7 from its locked state.

[0049] The self-locking fall arresting device 7 includes a self-locking housing 71 fixedly connected to the fixing rod 6. The self-locking housing 71 is divided into two parts. A self-locking mechanism 72 is provided inside the self-locking housing 71. The self-locking mechanism 72 includes two sets of self-locking plates 721 that are snapped and fixed to both sides of the inner wall of the self-locking housing 71. Each set of self-locking plates 721 is divided into two parts. A guide mounting groove 724 and a self-locking groove 725 are provided on the self-locking plate 721. The self-locking groove 725 is inclined on the self-locking plate 721. The top and bottom ends of the self-locking groove 725 are connected to the self-locking plate 724. The distances between the side walls are a and b, respectively, then a < b. A first roller group 722 and a second roller group 723 are rotatably arranged between the two relative guide mounting grooves 724 and the self-locking groove 725. A first connecting rod 726 and a second connecting rod 727 are rotatably arranged at both ends of each first roller group 722 and the second roller group 723. Each second connecting rod 727 is fixed to the end of the adjacent first connecting rod 726. The protrusion at the end of the second roller group 723 is located in the waist-shaped hole opened on the side of the first connecting rod 726.

[0050] See Figures 3-8 The first roller group 722 and the second roller group 723 each consist of two rollers. When in use, when a person needs to descend, the self-locking housing 71 is first driven to move downward. Since the self-locking groove 725 is a downwardly widening inclined groove, that is, the opening is larger at the bottom and smaller at the top, the self-locking plate 721 tends to move downward under the action of gravity. Correspondingly, under the action of the self-locking groove 725, the two rollers of the second roller group 723 move closer to each other, thereby clamping the wire rope located between the two rollers of the second roller group 723. The groove between the two rollers of the second roller group 723 is smaller than the diameter of the wire rope, thus ensuring that the wire rope is clamped. In the clamped state, the greater the gravity of descent, the greater the clamping force between the two rollers of the second roller group 723 on the wire rope, thereby achieving locking.

[0051] An unlocking device 73 is provided below the self-locking mechanism 72. A sliding frame 731 is connected between two opposing second connecting rods 727, and the two sliding frames 731 are rotatably connected. Guide posts 734 are slidably arranged on both sides of each sliding frame 731. A first fixing seat 732 is fixedly connected to the bottom surface of two guide posts 734 on the same side, and a second fixing seat 733 is fixedly connected to the bottom surface of two guide posts 734 on the other side. A first pull rod 735 is fixedly connected to the middle of the two sliding frames 731, and the second fixing seat... The bottom end of 733 is internally rotatably connected to a first lever 736 and a second lever 737. One end of the first lever 736 is hinged to a first pull rod 735, and the other end of the first lever 736 is hinged to the second lever 737. The bottom surfaces of the two first fixed seats 732 are fixedly connected to mounting seats 739. The bottom surface of the mounting seats 739 is hinged to a power rod 7310. The end of the power rod 7310 is connected to a second pull rod 738, and the other end of the second pull rod 738 is fixedly connected to the end of the second lever 737.

[0052] See Figures 3-8 When a person needs to descend from the escape device, pressing button 2 transmits power to the power rod 7310 via pneumatic device 8. See details... Figure 4 and Figure 5 When the end of the power rod 7310 is subjected to force and moves upward, the second pull rod 738 at the other end of the power rod 7310 moves downward. The second pull rod 738 drives the end of the second lever 737 to move downward, and the other end of the second lever 737 moves upward. Under the transmission action of the first lever 736, the end of the first lever 736, which is hinged to the second lever 737, moves upward. The end of the first lever 736, which is hinged to the first pull rod 735, moves downward, thereby causing the first pull rod 735 to drive the sliding frame 731 to move downward. Since the second connecting rod 727 and the sliding frame 731 are connected, the sliding frame 731 moves downward. The frame 731 is connected, and as the sliding frame 731 moves downward, it also drives the second connecting rod 727 to move downward. The second connecting rod 727 drives the second roller group 723 to move downward, thereby causing the two rollers in the second roller group 723 to move away from each other, increasing the distance between the two rollers, and thus releasing the clamping force on the wire rope, thereby releasing the locking state. With the locking state released, the human body moves downward under the action of gravity to escape. The descent speed is controlled by the clamping force of the two rollers of the second roller group 723 on the wire rope, which can be controlled by the button handle 2.

[0053] A locking device 5 is provided on the top surface of the left housing 11 or the right housing 12. The locking device 5 includes a locking outer shell 51 with a slit, which is fixedly installed on the top surface of the left housing 11 or the right housing 12. Locking blocks 53 are fixedly installed on both side walls of the locking outer shell 51. A rotating rod 52 is rotatably provided on the side wall of the locking outer shell 51. A curved rod 57 located inside the locking outer shell 51 is connected to the end of the rotating rod 52. A transmission rod 58 is provided on the curved rod 57. A positioning pin 59 is fixedly provided on the top surface of the transmission rod 58. A guide tube 510 is fixedly provided on the inner top wall of the locking outer shell 51. A meniscus 54 is rotatably provided on the upper surface of the locking outer shell 51. A limiting hole 56 adapted to the positioning pin 59 is opened on the upper surface of the meniscus 54 located inside the locking outer shell 51. A torsion spring 55 is sleeved on the outer surface of the rotating shaft of the meniscus 54 located inside the locking outer shell 51.

[0054] See Figure 12 and Figure 13 When not in use, the wire rope is locked between the two locking blocks 53. At this time, the meniscus 54 locks the wire rope in the locking blocks 53, thus locking it. When it is needed, the locking blocks 53 are rotated to drive the crank 57 to rotate. As the crank 57 rotates, it drives the transmission rod 58 to move up or down. When moving down, the positioning pin 59 slides in the guide tube 510 and the top of the positioning pin 59 disengages from the limiting hole 56, thus no longer locking the meniscus 54. Under the elastic force of the torsion spring 55, the meniscus 54 is moved, thus releasing the wire rope located in the locking blocks 53 from the locking blocks 53, no longer locking the wire rope, and releasing the locking state.

[0055] A disassembly device 9 is provided between the two self-locking anti-fall devices 7. The disassembly device 9 includes a first latching plate 91 and a second latching plate 92 disposed on the inner wall of the self-locking housing 71. A first latching block 93 is fixedly connected to the side of the first latching plate 91 near the second latching plate 92. A second latching block 94 adapted to the first latching block 93 is fixedly disposed on the side wall of the second latching plate 92 near the first latching plate 91. A second spring 95 is disposed between the second latching plate 92 and the inner wall of the self-locking housing 71. An installation plate 96 is disposed on one side of the left housing 11 or the right housing 12. A knob 97 is rotatably disposed on the surface of the installation plate 96. A rotating plate 98 is rotatably disposed on the other side of the installation plate 96. A turning rod 99 is fixedly connected to the inner side of the knob 97 and extends through the installation plate 96 into the through groove in the rotating plate 98. The upper and lower ends of the rotating plate 98 are respectively connected to the ends of the second latching plate 92 by connecting ropes.

[0056] See Figures 14-16When the self-locking fall arrestor 7 needs to be assembled or disassembled, specifically when disassembly is required, first turn the knob 97 to drive the rotating rod 99 to rotate, thereby driving the rotating plate 98 to rotate. Since both the upper and lower ends of the rotating plate 98 are connected to the second locking plates 92 in the two self-locking fall arrestors 7, the rotation of the rotating plate 98 causes the transmission rope connected to the second locking plate 92 to rotate, thereby driving the second locking plate 92 and the second locking block 94 installed on one side to move, so that the second locking block 94 disengages from the locking of the first locking block 93, and the first locking plate 91 and the second locking plate 92 separate, thereby separating the two parts of the self-locking housing 71 and completing the disassembly. Similarly, when assembly is required, first turn the knob 97 to pull the second locking plate 92, then the first locking plate 91 and the second locking plate 92 engage, and then release the knob 97. Under the elastic force of the second spring 95, the second locking plate 92 resets, so that the second locking block 94 and the first locking block 93 engage and lock, completing the installation.

[0057] The button handle 2 includes a handle body 21 installed on the sides of the left housing 11 and the right housing 12. A mounting bracket 22 is fixedly installed inside the handle body 21. A first slide rod 24 and a second slide rod 25 are slidably arranged in the horizontal groove and the vertical groove of the mounting bracket 22, respectively. A moving rod 26 is arranged between the first slide rod 24 and the second slide rod 25. A fixing block 27 is fixedly installed on the outer end of the moving rod 26. A button 23 is sleeved on the outer surface of the mounting bracket 22. A first spring 28 is arranged in the horizontal groove of the mounting bracket 22 between the end of the first slide rod 24 and the inner wall of the horizontal groove.

[0058] See Figure 18 When the button 23 is pressed, it is driven by the fixed block 27, which drives the first slide rod 24 and the second slide rod 25 to slide in the horizontal and vertical slots in the mounting bracket 22. This causes the moving rod 26 located between them to move, thereby driving the brake cable connected to the active rod 815 to move. Specifically, a hinge rod can be provided inside the handle body 21. For example, the hinge rod is hinged to the inner wall of the handle body 21. One end of the hinge rod is connected to the moving rod 26, and the other end is connected to the brake cable connected to the active rod 815. Referring to the movement principle of the pneumatic component 81 mentioned above, the movement of the active rod 815 causes the active airbag 818 to flatten, realizing the conversion of the grip force of the hand into gas pressure, thus realizing the force conversion. When the hand is released, the first slide rod 24, the second slide rod 25, the moving rod 26 and the button 23 return to their initial positions under the action of the elastic force of the first spring 28.

[0059] A waist belt 3 is fixedly installed on the front of the left shell 11 or the right shell 12; when a person stands on the pedal 4, the waist belt 3 fixes the person's waist to prevent the person from falling.

[0060] The working process of this invention is as follows: First, when a person stands on the pedal 4 and needs to move downwards, the button handle 2 is pressed, and the pressing force of the button handle 2 is transmitted to the pneumatic component 81. The pneumatic component 81 transmits the gas pressure to the transmission component 82, and the transmission component 82 then transmits the force to the self-locking anti-fall device 7, thereby changing the self-locking anti-fall device 7 from the locked state to the unlocked state, so that it can move downwards.

[0061] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
