DETAILED DESCRIPTION

[0057] In order to make the personnel in the technical field better understand the technical solutions in the present application, the technical solutions in the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person of ordinary skill in the art without making creative labor should belong to the protection scope of the present application.

[0058] The escape platform is a platform structure arranged on each building for forming a platform for escaping when a dangerous situation occurs. The existing buildings are usually provided with horizontally opened, sliding, upper suspended and lower suspended windows for lighting and ventilation, but due to the small opening sash and small opening area of the windows, a platform for people to gather cannot be formed after opening, which greatly reduces the probability of escape of the trapped person.

[0059] The escape platform provided by the application can be arranged at a position of each floor of a building where people can conveniently escape, and the platform can be used as a part of the building when closed, and can be used to realize functions such as lighting, ventilation and smoke exhaust of a window; when opened, the platform can form a platform on the outer facade of the building, and has a certain bearing capacity, so that the escaping people can gather on the platform to wait for rescue or use a centrifugal slow descent device to descend to a safe position to escape from danger.

[0060] As Figures 1-7 , the escape platform is arranged at a hole arranged on the building, and the position of the escape platform needs to be ensured to meet the facade effect requirement of the building. The escape platform comprises a bearing platform 4 and a fixed frame 1, the fixed frame 1 is arranged on the hole arranged on the facade of the building, the bearing platform 4 is movably connected with the fixed frame 1, a manual switch 2 is arranged on one side of the fixed frame 1 in the room, and the manual switch 2 is provided with a protection structure 21. In a normal case, the manual switch 2 is sealed in the protection structure 21 to avoid being accidentally touched. When used, the protection structure 21 is opened or removed, and then the manual switch 2 can be operated.

[0061] First sealing bodies 41 are arranged in the four side frames of the bearing platform 4. When the bearing platform 4 is in a closed state, the first sealing bodies 41 are pressed and sealed with second sealing bodies 12 arranged on the inner sides of the fixed frame 1. Guardrails 6 are arranged on the bearing platform 4 and are located at the edge positions of the bearing platform 4. The guardrails 6 are foldably hidden in first containing spaces 111 of two side frames 11 of the fixed frame 1 and are foldably hidden in second containing spaces 112 of an upper frame of the fixed frame.

[0062] Cable-stayed components 5 are arranged between the two side frames of the bearing platform 4 and the two side frames 11 of the fixed frame 1, and the cable-stayed components 5 are hidden in the first containing spaces 111 of the two side frames 11 of the fixed frame 1. First locking portions 42 are arranged on the side frames of the bearing platform 4, and the first locking portions 42 form a locked state with second locking portions 13 arranged on the side frames of the fixed frame.

[0063] After the bearing platform 4 is opened by the manual switch 2, the bearing platform 4 is connected with the lower frame of the fixed frame 1, so that the bearing platform 4 is rotated outward to a set position and stopped. Specifically, the connection and rotation can be realized by a hinged structure 131. When the bearing platform 4 is in an open state, people need to gather on the bearing platform 4 when escaping, and the bearing platform 4 should have a certain bearing capacity.

[0064] In order to ensure the safety of the escaping people, the bearing platform 4 forms a cantilever structure with the wall after being opened. The higher the escape hole is arranged and the longer the cantilever of the cantilever structure is, the more difficult it is for the bearing platform 4 to bear. Therefore, after the bearing platform 4 is opened, cable-stayed components 5 connected with the bearing platform 4 are arranged on the two sides of the fixed frame 1 to enhance the bearing strength of the bearing platform 4.

[0065] The inclined pulling component 5 can be a rod structure and is provided with a limiting device, which can make the inclined pulling component 5 run in a specified direction and make the inclined pulling component 5 be in a first containing space provided by the bearing platform 4 or the fixed frame 1 when the bearing platform 4 restores to the closed state. The inclined pulling component 5 can also be a telescopic component, which can stretch or contract to a specified position in a specified direction when the bearing platform 4 is opened, and the telescopic component can be in the containing space of the bearing platform 4 or the fixed frame 1 when the bearing platform 4 restores to the closed state. The inclined pulling component 5 can also be a rope or chain component, which can stretch to a specified position and stop running when the bearing platform 4 is in the opened state. One end of the rope or chain component can be provided with a counterweight structure or a friction structure, so as to make the bearing platform 4 slowly open.

[0066] At this time, the bearing platform 4 has the escape function, but in order to ensure that the escape personnel on the bearing platform 4 do not have the risk of falling, the side of the bearing platform 4 which is not connected with the wall body can be provided with a safety guardrail 6 when the bearing platform 4 is in the opened state. The guardrail 6 automatically rises when the bearing platform 4 is opened, so as to improve the safety of the bearing platform 4. A spring pneumatic telescopic device is arranged between the bearing platform 4 and the guardrail 6. Under the action of the pulling force or the pushing force of the spring pneumatic telescopic device, the guardrail 6 rises to a specified height and is locked during the opening process of the bearing platform 4. A gap for the escape personnel is arranged at the position of the guardrail of the bearing platform. After wearing the escape equipment, the escape personnel can safely escape through the gap without climbing over the guardrail. The number and position of the gap can be set according to the use condition. A handrail is arranged at the position of the gap. Before using the gap, the handrail is manually opened for escape.

[0067] The fixed frame 1 is also provided with a connecting part 8 of the backpack type centrifugal slow descent device. The escape personnel wears the escape backpack, the slow descent cable of the backpack type centrifugal slow descent device is connected with the connecting part 8, and the lifting of the backpack type centrifugal slow descent device is realized through the slow descent cable. Specifically, after the escape personnel wears the backpack type centrifugal slow descent device, the connecting end of the slow descent cable is connected with the connecting end of the connecting part 8. In the actual use process, the backpack type centrifugal slow descent device realizes slow descent under a certain gravity through a friction part. The slow descent cable is stored in a winch connected with the friction part. The whole component is installed in the backpack. The connecting end of the slow descent cable extends out of the backpack and is connected with the connecting part 8 arranged on the fixed frame 1. After the escape personnel fixes the backpack type centrifugal slow descent device on the body through the safety belt, the escape personnel can realize escape. The friction force of the friction part can be adjusted. The adjustment of the friction force can change the descending speed. The backpack type centrifugal slow descent device can be provided with a descending stopping device. The descending stopping device is manually controlled. The descending stopping device can extrude the friction part through an extrusion structure to increase the friction force. When the friction force is greater than the gravity, the descending is stopped. The descending stopping device can also extrude the slow descent cable through the extrusion structure to increase the friction force. When the friction force is greater than the gravity, the descending is stopped.

[0068] The escape platform is also provided with a restoring device 3 arranged on the fixed frame 1. After the carrying platform 4 completes the escape task, the functions and components of the carrying platform 4 are checked. If the functions and components of the carrying platform 4 are not damaged, the carrying platform 4 can be manually restored to the closed state from the indoor side by using the restoring device 3, and is locked by the locking structure arranged on the fixed frame 1 and the carrying platform 4. After the carrying platform 4 is restored to the initial state, the carrying platform 4 can be repeatedly used.

[0069] Specifically, a rope component can be used to connect the restoring device 3 and the carrying platform 4. One end of the rope component is connected to the carrying platform 4, and the other end is connected to a rope wheel of the restoring device 3. The rope wheel is controlled by the one-way movement principle of the pawl. A tool corresponding to the pawl is used to rotate the rope wheel, so that the rope component is wound on the rope wheel, and the carrying platform 4 is pulled to the initial state. A chain component can also be used. The chain is matched with a chain wheel. The chain is retracted by rotating the chain wheel. The retracted chain enters the accommodation space, pulls the carrying platform 4 to the initial state, and is locked. A lead screw structure can also be used to restore. The rotation of the lead screw makes the nut connected to the lead screw move linearly. The nut rope component, chain component or connecting rod component is linked with the escape platform. The nut moves in the set direction to restore the escape platform to the initial state and lock it.

[0070] The escape platform can also be provided with a centrifugal slow descending device 7, and the escape is realized by the centrifugal slow descending device 7. When used, the escape personnel need to wear an escape safety harness. After wearing the safety harness, the safety harness is connected to the slow descending rope 71 of the centrifugal slow descending device 7, and can be slowly descended to a safe position or the ground for escape. The centrifugal slow descending device 7 is arranged on the indoor side wall, and the number thereof can be set to be multiple. The connection end for connecting with the safety harness worn by the escape personnel extends out of the outdoor side, so that the escape personnel can quickly escape after wearing the safety harness and connecting with the connection end of the centrifugal slow descending device.

[0071] The centrifugal slow descending device 7 can also be arranged on the fixed frame 1, and the number thereof can be set to be multiple. The connection end 72 of the centrifugal slow descending device 7 arranged on the fixed frame 1 also extends out of the outdoor side, so as to facilitate the escape personnel to quickly escape.

[0072] The centrifugal slow descent device 7 can also be arranged separately from the bearing platform 4, for example, a first connecting part and a third locking part connected with the centrifugal slow descent device 7 are arranged on the fixed frame 1 or the bearing platform 4, and the number of the first connecting part and the third locking part is at least one. After the bearing platform 4 is opened, the escape personnel fix the centrifugal slow descent device 7 to the first connecting part, and lock through the third locking part. After the escape personnel wear the safety harness, the safety harness will be connected with the connecting end 72 of the centrifugal slow descent device. It needs to be noted that the number of the above-mentioned first connecting part and the third locking part is multiple. In the actual use process, it is not necessary to use multiple first connecting parts and third locking parts at the same time to realize the escape function. One escape or one escape personnel only needs to use a pair of first connecting part and third locking part. The multiple first connecting part and third locking part is arranged on one hand to facilitate the escape personnel to fix the safety harness, and on the other hand to facilitate multiple escape personnel to escape at the same time.

[0073] The centrifugal slow descent device 7 can also be arranged as a reciprocating structure, for example, each centrifugal slow descent device 7 is provided with two second connecting parts, and the two second connecting parts cannot be used at the same time. When escaping, the first escape personnel first uses one of the second connecting parts to descend to the safety position or the ground, and then takes off the escape harness. At this time, the personnel waiting to escape on the bearing platform 4 can use the other second connecting part to descend. When the second personnel waiting to escape descends, the connecting end 72 used by the first escape personnel with the escape harness is recycled to the initial position on the bearing platform 4, and can be used again by the escape personnel. In this way, in the subsequent escape process of the escape personnel, repeated fixing work is not needed. After wearing the escape harness, the escape personnel can quickly escape from the dangerous environment.

[0074] The escape platform can also be provided with a fireproof heat insulation curtain 9. The fireproof heat insulation curtain 9 is arranged on the indoor side of the upper edge frame of the fixed frame 1. The guide limiting part of the fireproof heat insulation curtain 9 is arranged on the indoor side of the side edge frame 11 of the fixed frame 1. After the escape personnel reaches the bearing platform 4, the fireproof heat insulation curtain 9 can be manually pulled down, thereby forming a partition seal between the bearing platform 4 and the indoor side of the building. At this time, if there are still personnel in the room who have not escaped to the bearing platform 4, they can also open the fireproof heat insulation curtain 9 from the indoor side. After reaching the bearing platform 4, the fireproof heat insulation curtain 9 is closed again to form a partition layer, so that the space of the bearing platform 4 is safer, thereby gaining more escape time.

[0075] The fireproof heat insulation curtain 9 is rotated and contracted under the shaft of the containing space by the spring force. When the downward pulling force is greater than the spring force, the heat insulation curtain runs downward along the two side guide limiting parts. When the heat insulation curtain runs to the set position, a locking structure is arranged at the set position. The locking structure can be opened from the indoor side and the outdoor side, so that the personnel who have not escaped to the escape platform can continue to hide and escape.

[0076] It should be noted that the centrifugal slow descent device 7 provided by the embodiment of the present application can also be used alone and is not limited to the building scene, but also can be used in other scenes with height difference, such as a tower crane, a mountain, a bridge, a mine or a ship.

[0077] Based on the foregoing escape platform, the specific structure of the centrifugal slow descent device 7 is described in detail as follows.

[0078] Referring to Figures 8-10 The embodiment of the present application provides a slow descent device with a brake structure. The slow descent device comprises a fixed part 710, a cable assembly 730 and a brake mechanism 760 arranged on the fixed part 710. A user can slow down by the cable assembly 730, control the descending speed by the brake mechanism 760 to achieve soft landing, or stop descending at any time by the brake mechanism 760 to land on a suitable floor.

[0079] As shown in Figure 8 The fixed part 710 can be a metal connecting seat, which comprises a fixed plate arranged horizontally and a connecting plate arranged vertically. The fixed plate can be fixed on the facade of a building or an escape platform. A plurality of connecting plates are arranged vertically on the fixed plate.

[0080] The brake mechanism 760 comprises a brake rope 761, a handheld part 762, a storage disc 763, an operating piece 764, a brake piece 765 and a connecting part.

[0081] The connecting part is arranged on a wall or an escape platform. One end of the brake rope 761 is connected with the connecting part, and the other end is wound on the storage disc 763. The storage disc 763 is arranged rotatably in the handheld part 762.

[0082] The brake piece 765 can be a brake pad, and the operating piece 764 can be a button. The operating piece 764 is arranged on the handheld part 762. One end of the operating piece 764 is connected with the brake piece 765 in the handheld part 762, and the other end of the operating piece 764 extends out of the handheld part 762.

[0083] The operating piece 764 is used to make the brake piece 765 abut against the storage disc 763 to hinder the rotation of the storage disc 763.

[0084] When a user descends by the cable assembly 730, the handheld part 762 is carried, and the storage disc 763 rotates freely to release the brake rope 761. When braking is needed, the operating piece 764 is pressed to make the brake piece 765 abut against the storage disc 763 to hinder the rotation of the storage disc 763, so that the brake rope 761 is no longer released, and the user realizes braking by the brake rope 761 with a fixed length.

[0085] As shown in Figures 8-10As shown, in an embodiment, the escape slow descent device further comprises a rotating member, the cable assembly 730 directly or indirectly drives the rotating member to rotate synchronously;

[0086] The connecting part comprises a brake component 766 and a brake device 767;

[0087] The brake component 766 is arranged on the fixed part 710 or the escape platform, one end of the brake rope 761 is connected with one end of the brake component 766, and the brake device 767 is connected with the other end of the brake component 766;

[0088] The brake component 766 can be a seesaw structure, the seesaw has opposite first and second ends, the brake device 767 can be an arc-shaped brake pad, which cooperates with the rotating member, the brake device 767 is arranged on the upper surface of the first end of the seesaw, and the top end of the brake rope 761 is connected with the lower surface of the second end of the seesaw; when the brake is pressed by the operating member 764, the pulling force of the brake rope 761 on the second end of the seesaw increases, the first end of the seesaw is lifted, the brake device 767 moves upward, abuts against the outer wall of the rotating member, and blocks the rotation of the rotating member, so as to block the rotation release of the cable assembly 730;

[0089] During the descending process, when the escape personnel is about to descend to the safe floor, the operating member 764 is manually pressed, the brake piece 765 prevents the storage disc 763 from rotating, the brake rope 761 is tightened, the brake component 766 drives the brake device 767 to prevent the rotating member from rotating under the pulling of the brake rope 761, so that the cable assembly 730 stops rotating, and the escape personnel can stop at the selected safe floor and break the window into the safe floor to escape by using the safety hammer in the safety harness bag.

[0090] As shown, Figure 10 The cable of the cable assembly 13 extends downward, the brake component 766 and the brake device 767 are arranged on the fixed part 710 and are respectively located on the left and right sides of the cable;

[0091] The brake device 767 can be a fixed clamping block, and the side of the fixed clamping block facing the cable is a first clamping surface;

[0092] The brake component 766 can be composed of a connecting rod structure and a moving clamping block, the brake rope 761 is connected with one end of the connecting rod structure, the other end of the connecting rod structure is connected with the moving clamping block, and the side of the moving clamping block facing the cable is a second clamping surface;

[0093] When the brake rope 761 is pulled downward, the connecting rod structure drives the moving clamping block to move toward the cable side, so that the brake component 766 and the brake device 767 clamp the cable, that is, the first clamping surface and the second clamping surface clamp the cable, so that the cable is lowered to reduce the downward movement speed or does not move downward, the cable assembly 730 is slowly released or is not released, and the effect of deceleration or braking is achieved.

[0094] In an embodiment, the escape slow descent device further comprises a rotating shaft 720;

[0095] The rotating shaft 720 penetrates through the plurality of fixed plates of the fixed part 710 and is rotationally connected with the fixed part 710. The cable assembly 730 is fixedly connected with the rotating shaft 720 and rotates synchronously with the rotating shaft 720.

[0096] When the escape personnel descend through the cable assembly 730, the cable assembly 730 drives the rotating shaft 720 to make a first rotating motion, which can be a clockwise rotating motion.

[0097] As shown in the drawings, Figure 8 In an embodiment, the rotating member is the rotating shaft 720, the outer wall of the rotating shaft 720 is provided with anti-skid lines, and the brake device 767 is an arc-shaped brake pad matched with the rotating shaft 720.

[0098] When the brake rope 761 is pulled, the brake component 766 makes the brake device 767 abut against the outer wall of the rotating shaft 720 to hinder the rotating shaft 720 and the cable assembly 730 from rotating.

[0099] As shown in the drawings, Figure 9 In an embodiment, the rotating member is the brake disc 768, which can be in a disc-shaped or cylindrical structure. The brake disc 768 is fixedly connected with the rotating shaft 720 and coaxially arranged, i.e., the brake disc 768 rotates synchronously and in the same direction with the rotating shaft 720.

[0100] In the process of descending, the cable assembly 730 drives the rotating shaft 720 and the brake disc 768 to make a first rotating motion. When the escape personnel are about to descend to the safe floor, the brake rope is pulled to make the brake component 766 drive the brake device 767 to abut against the brake disc 768, thereby preventing the brake disc 768 from rotating, and the rotating shaft 720 and the cable assembly 730 also stop running. The escape personnel can stop at the selected safe floor and use the safety hammer in the safety kit to break the window and escape to the safe floor.

[0101] Referring to the drawings, Figure 8 In some embodiments, the cable assembly 730 comprises a cable 731 and a rotating disc 732.

[0102] The rotating disc 732 is sleeved with the rotating shaft 720 and rotationally connected with the rotating shaft 720. The side wall of the rotating disc 732 is fixedly connected with the end of the friction ring 740. The rotating disc 732 and the friction ring 740 rotate in the same direction and at the same speed.

[0103] The cable 731 can be a cable. The cable 732 is wound on the rotating disc 732. The outer end of the cable 731 is provided with a connecting ring.

[0104] When the escape personnel descend through the cable 731, the cable 731 drives the rotating disc 732 and the friction ring 740 to make a first rotating motion.

[0110] By arranging the two rotating discs 732 and the two brake mechanisms 760 on the rotating shaft 720, the left and right sides of the slow descending device can be used for personnel escape.

[0111] When the left cable 731 is released and moves downward to drive the left rotating disc 732 to rotate clockwise, the rotating shaft 720 rotates counterclockwise, the rotating shaft 720 drives the right rotating disc 732 to rotate clockwise, and the right cable 731 is wound on the right rotating disc 732.

[0112] After the left personnel descend to the safety area, the left harness bag is connected with the left cable 731, and the right personnel wears the harness bag and connects the other harness bag with the end of the right cable 731 with the quick connecting ring, and connects the extending end of the brake rope on the harness bag with the right brake component of the right brake device, and then descends and escapes. When the right cable 731 is pulled down, the right rotating disc rotates to drive the rotating shaft 720 to rotate clockwise, the rotating shaft 720 drives the left rotating disc 732 to rotate counterclockwise, the left cable 731 is wound on the left rotating disc 732, and the left harness bag is also brought to the escape position, and the harness bag can be repeatedly used for multiple people to escape.

[0117] The rotating shaft 720 drives the first guide 751 and the friction block 752 to rotate synchronously, the outer wall of the friction block 752 and the inner wall of the friction ring 740 are dynamically rubbed, with the increase of the descending speed of the escape personnel, the rotating speed of the friction ring 740 and the rotating disc 732 is increased, and then the rotating speed of the rotating shaft 720 and the first guide 751 is increased, the centrifugal force outwardly borne by the friction block 752 is increased, the pressure of the friction block 752 on the friction ring 740 is increased, the relative speed between the friction ring 740 and the friction block 752 is increased, the dynamic friction force between the friction ring 740 and the friction block 752 is increased, and then the reverse force resisting the first rotating motion applied by the friction block 752 to the friction ring 740 is increased, and then the rotating speed of the friction ring 740 and the rotating disc 732 is reduced, and then the descending speed of the escape personnel is reduced, so that the escape personnel is prevented from being hurt due to the too fast descending speed.

[0118] Referring to Figure 12As shown, in some embodiments, the reciprocating cycle escape slow descent device further comprises a slow release mechanism 770, which comprises:

[0119] A friction plate 771 is slidably arranged outside the rotating shaft 720 and fixed to the fixed seat 710, and the friction plate 771 can be a circular friction plate;

[0120] A moving piece 772 is arranged on the rotating shaft 720, and the moving piece 772 can be a nut;

[0121] A friction disc 773 is slidably arranged outside the rotating shaft 720, and the friction disc 773 is an annular structure, sleeved with the rotating shaft 720. The friction disc 773 is located between the friction plate 771 and the moving piece 772, and the friction disc 773 is attached to the friction plate 771.

The inner end of the friction disc 773 is provided with a limiting groove, and the limiting strip is connected with the limiting groove. The limiting strip can slide in the limiting groove in a small range, so that the friction disc 773 rotates synchronously with the rotating shaft 720, and the friction disc 773 can slide on the rotating shaft 720 in a small range;

[0122] A second elastic piece 774 is arranged between the moving piece 772 and the friction disc 773, and the second elastic piece 774 can be a spring or an air cylinder. The two ends of the second elastic piece 774 in the extending direction are respectively in abutment with the moving piece 772 and the friction disc 773.

[0123] The friction disc 773 is attached to the friction plate 771. When the rotating shaft 720 drives the friction disc 773 to rotate, the friction disc 773 and the friction plate 771 generate dynamic friction, which hinders the rotation of the rotating shaft 720, and further hinders the rotation of the rotating disc 732, thereby reducing the descent speed of the escape personnel.
