Description

Technical Field

[0001] This application relates to the field of escape platform technology, and more particularly to an escape platform railing and an escape platform. Background Technology

[0002] In dangerous situations in high-rise buildings, people inside are often unable to escape quickly. This is especially true in scenarios such as fires, when elevators are unusable or unsuitable for use, and safety passages (stairs) have limited speed and capacity, which greatly delays people's escape and can easily create serious safety hazards.

[0003] Escape platforms are typically installed in building openings designed for people to escape in emergency situations, allowing for rapid evacuation of people inside. When not in use, escape platforms are usually folded and hidden inside the wall, locked to the frame installed in the building opening. In case of an emergency, a manual unlocking device is required to unfold the escape platform.

[0004] However, once the escape platform is deployed, there is no protective device around it, which poses a risk of people falling while on the platform. Utility Model Content

Detailed Implementation

[0100] This application provides an escape platform railing and an escape platform to solve the technical problem that, after the current escape platform is released, there is no protective device around the escape platform, which poses a risk of falling for the escapers when they are on the platform.

[0101] For example, an escape platform is a structure installed on each floor of a building that can be opened to form an escape platform on the exterior wall surface in the event of a dangerous situation. Existing buildings typically have casement, sliding, top-hung, and bottom-hung windows for lighting and ventilation, but because the opening sashes are small and the opening area is small, they cannot form a platform for people to gather when opened, which greatly reduces the chances of trapped people escaping.

[0102] The escape platform involved in this application can be set in a location on each floor where escape is convenient. When closed, the platform can be part of the building itself and can also be used to realize functions such as window lighting, ventilation and smoke exhaust. When opened, it can form a platform on the exterior of the building with a certain load-bearing capacity. People can gather on the platform to wait for rescue or use the descent device to descend to a safe location to escape danger.

[0103] like Figures 1 to 7 The escape platform provided in this embodiment is installed in an opening in the building, while ensuring that the location of the escape platform meets the requirements of the building's facade. The escape platform includes a support platform 4 and a fixed frame 1. The fixed frame 1 is set in the opening in the building wall. The support platform 4 and the fixed frame 1 are movably connected. A manual switch 2 is provided on the indoor side of the fixed frame 1. The manual switch 2 is provided with a protective structure 21. Under normal circumstances, the manual switch 2 is sealed inside the protective structure 21 to prevent accidental contact. When in use, the manual switch 2 can be operated by opening or removing the protective structure 21.

[0104] The support platform 4 is provided with a first sealing body 41 inside its four-sided frame. When the support platform 4 is in the closed state, the first sealing body 41 is squeezed and sealed with the second sealing body 12 provided inside the fixed frame 1. The support platform 4 is provided with a guardrail 6. The guardrail 6 is located at the edge of the support platform 4 and is foldably hidden in the first receiving space 111 of the two side frames 11 of the fixed frame 1, and foldably hidden in the second receiving space 112 of the upper frame of the fixed frame.

[0105] The inclined pull member 5 is disposed between the two sides of the bearing platform 4 and the two side frames 11 of the fixed frame 1, and the inclined pull member 5 is hidden in the first receiving space 111 of the two side frames 11 of the fixed frame 1; the frame of the bearing platform 4 is provided with a first locking part 42, and the first locking part 42 and the second locking part 13 provided on the frame of the fixed frame form a locking state.

[0106] After the support platform 4 is opened by the manual switch 2, the support platform 4 is connected to the lower frame of the fixed frame 1, so that the support platform 4 rotates to the outside and stops at the set position. Specifically, the connection and rotation can be achieved through the hinge structure 131. When the support platform 4 is in the open state, people need to gather on the support platform 4 when escaping. The support platform 4 should have a certain load-bearing capacity.

[0107] To ensure the safety of those escaping, the support platform 4 forms a cantilever structure with the wall after it is opened. The higher the escape opening is set and the longer the cantilever of the cantilever structure, the less favorable it is for the support platform 4 to bear the load. Therefore, after the support platform 4 is opened, inclined tie members 5 are provided on both sides of the fixed frame 1 to connect with the support platform 4, so as to enhance the load-bearing strength of the support platform 4.

[0108] The inclined pull component 5 can be a rod-like structure with a limiting device, which allows the inclined pull component 5 to move in a specified direction when the bearing platform 4 returns to the closed state, and to be located within the first accommodating space provided by the bearing platform 4 or the fixed frame 1. The inclined pull component 5 can also be a telescopic component, which extends or retracts to a set position in a set direction when the bearing platform 4 is open, and is located within the accommodating space of the bearing platform 4 or the fixed frame 1 when the bearing platform 4 returns to the closed state. The inclined pull component 5 can also be a rope or chain-like component, which extends to a set position and stops moving when the bearing platform 4 is in the open state. One end of the rope or chain-like component can be provided with a counterweight structure or friction structure to enable the bearing platform 4 to open slowly.

[0109] At this point, the support platform 4 is equipped with an escape function. However, to ensure that escapers on the support platform 4 do not fall, a safety railing 6 can be installed on the side of the support platform 4 that is not connected to the wall when the support platform 4 is in the open state. When the support platform 4 is opened, the railing 6 automatically rises to improve the safety of the support platform 4. A spring-loaded pneumatic telescopic device is installed between the support platform 4 and the railing 6. During the opening process of the support platform 4, the railing 6 rises to a set height and locks under the pulling or pushing force of the spring-loaded pneumatic telescopic device. The railing of the support platform has an opening for escapers to use. After putting on escape equipment, escapers can safely escape through the opening without having to climb over the railing. The number and location of the openings can be set according to usage. A railing is installed at the opening location. Before using the opening, the railing must be manually opened for escape.

[0110] The fixed frame 1 is also equipped with a connecting part 8 for a backpack-type descent device. The escapee puts on the escape backpack, and the descent cable of the backpack-type descent device connects to the connecting part 8, enabling the backpack-type descent device to rise and fall. Specifically, after the escapee puts on the backpack-type descent device, the connecting end of the descent cable connects to the connecting end of the connecting part 8. In actual use, the backpack-type descent device descends slowly under a certain gravity through a friction part. The descent cable is stored in a winch connected to the friction part. The entire component is installed inside the backpack, with the connecting end of the descent cable extending out of the backpack and connecting to the connecting part 8 on the fixed frame 1. The escapee can escape after securing the backpack-type descent device to their body with a safety belt. The friction force of the friction part is adjustable, allowing for changes in the descent speed. The backpack-type descent device can be equipped with a descent stop device, which can be manually controlled. The descent stop device can increase the friction force by squeezing the friction part through a compression structure, stopping the descent when the friction force exceeds the gravity; or it can increase the friction force by squeezing the descent cable through a compression structure, stopping the descent when the friction force exceeds the gravity.

[0111] The escape platform is also equipped with a recovery device 3, which is set on the fixed frame 1. After the carrying platform 4 is opened to complete the escape mission, check the various functions and components of the carrying platform 4. If there is no damage to the various functions and components of the carrying platform 4, the recovery device 3 can be used to manually restore the carrying platform 4 to the closed state from the indoor side, and lock it through the locking structure set 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 still be reused.

[0112] Specifically, a rope-like component can be used to connect the recovery device 3 and the support platform 4. One end of the rope-like component is connected to the support platform 4, and the other end is connected to the rope wheel of the recovery device 3. The rope wheel is controlled by the unidirectional movement principle of the pawl. A tool corresponding to the pawl can be used to rotate the rope wheel, causing the rope-like component to wrap around the rope wheel and pull the support platform 4 back to its initial state. Alternatively, a chain-like component can be used. The chain cooperates with the sprocket. By rotating the sprocket, the chain is contracted. The contracted chain enters the set receiving space, pulling the support platform 4 back to its initial closed state and locking it. Alternatively, a screw structure can be used to achieve recovery. Rotating the screw causes the screw nut connected to the screw to move linearly. The screw nut rope-like component, chain component, or connecting rod component is connected to the escape platform. The screw nut moves in a set direction to restore the escape platform to its initial state and lock it.

[0113] The escape platform can also be equipped with a descent device 7, and escape can be achieved through the descent device 7. When using it, the escaper needs to wear an escape safety harness. After wearing it, the safety harness is connected to the descent cable 71 of the descent device 7, and can be slowly descended to a safe position or the ground to escape. The descent device 7 is installed on the indoor side wall, and the number can be set to multiple. The connecting end for connecting with the safety harness worn by the escaper extends to the outdoor side, so that the escaper can quickly escape after wearing the safety harness and connecting with the descent device.

[0114] The descent device 7 can also be installed on the fixed frame 1, and the number can be set to multiple. The connection end 72 of the descent device 7 installed on the fixed frame 1 also extends to the outside of the room, which facilitates the rapid escape of the escaped personnel.

[0115] The descent device 7 can also be set separately from the support platform 4. For example, a first connecting part and a third locking part connected to the descent device 7 can be provided on the fixed frame 1 or the support platform 4, and the number of the first connecting part and the third locking part is at least one. After the support platform 4 is opened, the escapee fixes the descent device 7 to the first connecting part and locks it through the third locking part. After the escapee puts on the safety harness, the safety harness will be connected to the connecting end 72 of the descent device. It should be noted that the number of the first connecting part and the third locking part is set to multiple. In actual use, it is not necessary to use multiple first connecting parts and third locking parts at the same time to achieve the escape function. Instead, one escapee or one escapee only needs to use one pair of first connecting parts and third locking parts. Setting multiple first connecting parts and third locking parts makes it convenient for the escapee to fix the safety harness and also makes it convenient for multiple escapees to carry out escape actions at the same time.

[0116] The descent device 7 can also be configured as a reciprocating structure. For example, each descent device 7 is provided with two second connecting parts. The two second connecting parts cannot be used at the same time. When escaping, the first person to escape uses one of the second connecting parts to descend to a safe location or the ground and then takes off the escape harness. At this time, the person waiting to escape on the carrying platform 4 can use the other second connecting part to descend. When the second person to escape descends, the connecting end 72 used by the first person to escape, along with the escape harness, is retrieved to the initial position on the carrying platform 4 and can be used by the person to escape again. In this way, during the subsequent escape process, there is no need to perform repeated fixing work. After putting on the escape harness, the person can quickly escape from the dangerous environment.

[0117] The escape platform may also be equipped with a fireproof and heat-insulating curtain 9. The fireproof and heat-insulating curtain 9 is set on the indoor side of the upper frame of the fixed frame 1, and the guide part of the fireproof and heat-insulating curtain 9 is set on the indoor side of the side frame 11 of the fixed frame 1. After the escape personnel reach the carrying platform 4, they can manually pull down the fireproof and heat-insulating curtain 9, thereby forming a partition and sealing between the carrying 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 carrying platform 4, they can also open the fireproof and heat-insulating curtain 9 from the indoor side. After reaching the carrying platform 4, they can close the fireproof and heat-insulating curtain 9 again to form a partition layer, making the space of the carrying platform 4 safer and gaining more escape time.

[0118] The fireproof and heat-insulating curtain 9 retracts under the axis of the accommodating space by rotating with spring force. When the downward pulling force is greater than the spring force, the heat-insulating curtain moves downward along the guide sections on both sides and moves to the set position. The set position is equipped with a locking structure, which can be opened from the indoor and outdoor sides, so that people who have not yet escaped to the escape platform can continue to hide and escape.

[0119] It should be noted that the slow descent device 7 provided in this application embodiment can also be used independently and is not limited to architectural scenarios, but can also be used in other scenarios with height differences, such as tower cranes, mountains, bridges, mines, or ships.

[0120] Based on the escape platform described above, the specific structure of guardrail 6 will be explained in detail below:

[0121] See Figures 8 to 15 This application provides an escape platform guardrail, namely the guardrail 6 mentioned above, which specifically includes:

[0122] Depend on Figure 14 As can be seen, the first aspect of this application provides an escape platform guardrail, applied to an escape platform including a support platform 4 and a fixed frame 1, such as... Figure 8 As shown, the supporting platform 4 is rotatably connected to the fixed frame 1; it includes: a handrail 61, which is U-shaped; the handrail 61 is connected to a guardrail lifting device, and when the supporting platform 4 rotates away from the room, the handrail 61 is lifted by the guardrail lifting device until the supporting platform 4 is perpendicular to the fixed frame 1, at which point the distance between the handrail 61 and the supporting platform 4 reaches a preset value; and a support 62, which is disposed between the handrail and the supporting platform; this allows the guardrail 6 to fold within the accommodating space of the fixed frame 1 and prevents escapers from falling off the supporting platform. The risk of falling from platform 4 occurs; a fixing part 101 is slidably connected to the receiving space of the fixing frame 1; the fixing part 101 is rotatably connected to both ends of the handrail part 61; wherein, when the distance between the supporting platform 4 and the handrail part 61 gradually increases, the support part 62 unfolds; when the distance between the supporting platform 4 and the handrail part 61 reaches a preset value, the support part 62 unfolds to a set value, that is, the unfolded length of the support part 62 is equal to the preset value; when the distance between the supporting platform 4 and the handrail part 61 reaches the preset value, the support part, the handrail part, and the supporting platform achieve self-locking. A self-locking structure is provided between the support part, the handrail part, and the supporting platform. When the distance between the supporting platform 4 and the handrail part 61 reaches a preset value, the support part 62 unfolds to the set value and locks, preventing escapees on the supporting platform 4 from pressing the upper handrail part 61 of the guardrail 6, causing the guardrail 6 to change from the unfolded state to the folded state, thereby causing the escapees to fall from the guardrail 6. An escape passage reserved exit is provided on the side of the support part 62 near the fixed frame 1. The reserved exit is used for escapees to escape to the ground through the escape device, and can also be used to connect the escape passage of fire trucks.

[0123] This application provides an escape platform railing. When the support platform 4 is opened, the railing 6, which is folded and hidden in the accommodating space of the fixed frame 1, is also opened. When the support platform 4 is opened to a set position, the railing 6 is also unfolded to the set position and locked. The locking function is to prevent the escape personnel on the support platform 4 from pressing the upper handrail 61 of the railing 6, causing the railing 6 to change from the unfolded state to the folded state, thereby causing the escape personnel to fall from the railing 6.

[0124] Depend on Figure 8 It can be seen that the connecting rod can be configured as a double-section folding type. The support part 62 includes: a first connecting rod 621, one end of which is rotatably connected to the handrail part 61; a second connecting rod 622, one end of which is rotatably connected to the support platform 4, and the other end of which is rotatably connected to the first connecting rod 621 via a connecting shaft 6211; the second connecting rod 622 and the first connecting rod 621 are of equal length; wherein, the first connecting rod 621 disposed between the handrail part 61 and the support platform 4 is parallel to each other; the second connecting rod 622 disposed between the handrail part 61 and the support platform 4 is parallel to each other. By rotating the first connecting rod 621 onto the second connecting rod 622, the first connecting rod 621 is folded onto the second connecting rod 622, so that the guardrail 6 is folded within the accommodating space of the fixed frame 1, and the risk of escapers falling from the support platform 4 can be prevented. The distance between adjacent connecting rods disposed between the handrail part 61 and the support platform 4 is equal.

[0125] like Figure 9As shown, the connecting rod can be configured as a multi-section folding form. The support part 62 includes: a third connecting rod 623, one end of which is rotatably connected to the handrail part 61; a connecting rod part 624, one end of which is rotatably connected to the other end of the third connecting rod 623 via a connecting shaft 6211; the connecting rod part 624 is at least one connecting rod; and a fourth connecting rod 625, one end of which is rotatably connected to the bearing platform 4, and the other end of which is connected to the support part 61 via the connecting shaft 6211. The connecting rod portion 624 is rotatably connected; the fourth connecting rod 625, the connecting rod portion 624, and the third connecting rod 623 are of equal length; wherein, the fourth connecting rod 625, which is disposed between the handrail portion 61 and the supporting platform 4, is parallel to each other; the connecting rod portion 624, which is disposed between the handrail portion 61 and the supporting platform 4, is parallel to each other; the third connecting rod 623, which is disposed between the handrail portion 61 and the supporting platform 4, is parallel to each other; the fourth connecting rod 625 and the third connecting rod 623 are parallel to each other. By rotatably connecting the third connecting rod 623 to the connecting rod portion 624, and rotatably connecting the connecting rod portion 624 to the fourth connecting rod 625, the guardrail 6 can be folded within the accommodating space of the fixed frame 1, and the risk of escapers falling from the supporting platform 4 can be prevented; compared with the double-section folding form, the multi-section folding form can be set with more connecting rods, thereby making the guardrail 6 more robust and sturdy; for example, the number of connecting rods can be set even more, which can be set according to actual needs.

[0126] like Figure 16 As shown, the support portion 62 includes: at least one fifth link 626, one end of which is connected to the handrail portion 61, and the other end of which is connected to the support platform 4; a first sliding portion 6261 is provided on the fifth link 626; at least one sixth link 627, one end of which is connected to the handrail portion 61, and the other end of which is connected to the support platform 4; a second sliding portion 6271 is provided on the sixth link 627; a connecting shaft 6211 passes through the first sliding portion 6261 and the second sliding portion 6271, so that the sixth link 627 is connected to the fifth link 626. The two ends of the fifth link 626 and the sixth link 627 are slidably connected to the handrail portion 61 and the support platform 4, respectively, and the support platform 4 is in a closed state, as shown. Figure 16 As shown; the supporting platform 4 is in the open state, as... Figure 17 As shown; compared with the above-mentioned linkage structure, the linkage structure in this embodiment uses fewer linkages, which can reduce installation time and cost.

[0127] like Figure 20 and 22As shown, the handrail portion 61 is provided with a first sliding portion; the support portion 62 includes at least one seventh link 628, one end of the seventh link 628 being connected to the first sliding portion via a connecting shaft 6211, and the other end being connected to the bearing platform 4; wherein, when the distance between the bearing platform 4 and the handrail portion 61 reaches a preset value, the locking shaft 6291 of the seventh link 628 and the locking groove 6292 of the first sliding portion achieve self-locking, as shown. Figure 23 As shown. It is understood that when the distance between the handrail 61 and the supporting platform 4 does not reach the preset value, the locking shaft 6291 will not engage with the locking groove 6292, and the seventh link 628 can slide into the first sliding part, thus folding for storage; when the distance between the handrail 61 and the supporting platform 4 reaches the preset value, the locking shaft 6291 of the seventh link 628 and the locking groove 6292 of the first sliding part achieve self-locking, preventing escapees on the supporting platform 4 from pressing the upper handrail 61 of the guardrail 6, causing the guardrail 6 to change from an unfolded state to a folded state, thereby causing the potential hazard of escapees falling from the guardrail 6.

[0128] like Figure 21 As shown, a second sliding part is provided on the outer side of the bearing platform 4; the support part 62 includes: one end of the eighth link 629 is connected to the second sliding part through a connecting shaft 6211, and the other end is connected to the handrail part 61; wherein, when the distance between the bearing platform 4 and the handrail part 61 reaches a preset value, the locking shaft 6291 of the eighth link 629 and the locking groove 6292 of the second sliding part achieve self-locking. Understandably, when the distance between the handrail 61 and the support platform 4 does not reach the preset value, the locking shaft 6291 will not engage with the locking groove 6292, and the eighth link 629 can slide to the second sliding part for folding and storage. When the distance between the handrail 61 and the support platform 4 reaches the preset value, the locking shaft 6291 of the eighth link 629 and the locking groove 6292 of the second sliding part achieve self-locking, preventing escapees on the support platform 4 from pressing the upper handrail 61 of the guardrail 6, causing the guardrail 6 to change from the unfolded state to the folded state, thereby causing the potential hazard of escapees falling from the guardrail 6.

[0129] like Figure 10As shown, the linkage-type guardrail can also be a scissor-shaped double-section folding type. The support part 62 includes: a first scissor-shaped connecting rod 630, which is X-shaped, and both ends of the first scissor-shaped connecting rod 630 are rotatably connected to the handrail part 61; and a second scissor-shaped connecting rod 631, which is X-shaped, and both ends of the second scissor-shaped connecting rod 631 are rotatably connected to the bearing platform 4, and the other two ends are rotatably connected to the other two ends of the first scissor-shaped connecting rod 630 through a connecting shaft 6211. By rotatably connecting the two ends of the first scissor-shaped connecting rod 630 to the two ends of the second scissor-shaped connecting rod 631, the guardrail 6 can be folded within the accommodating space of the fixed frame 1, and the risk of escapers falling from the bearing platform 4 can be prevented. Compared with the above-mentioned double-section folding and multi-section folding guardrail structures, the scissor-folding guardrail structure is more robust and sturdy. For example, the linkage-type guardrail can also be a scissor-shaped multi-section folding type, which can be set according to actual needs.

[0130] like Figure 11 As shown, the guardrail 6 can also be a plate-shaped folding structure. The first connecting rod 621 and the second connecting rod 622 further include: a first plate-shaped connecting rod assembly 6221; a second plate-shaped connecting rod assembly 6222, the second plate-shaped connecting rod assembly 6222 being rotatably connected to one end of the first plate-shaped connecting rod assembly 6221 via the connecting shaft 6211; the second plate-shaped connecting rod assembly 6222 and the first plate-shaped connecting rod assembly 6221 have the same length; wherein, the first plate-shaped connecting rod assembly 6221 and the second plate-shaped connecting rod assembly 6222 are provided with a first state position and a second state position; when located in the first state position, the angle between the first plate-shaped connecting rod assembly 6221 and the second plate-shaped connecting rod assembly 6222 and the fixed frame 1 reaches a first preset angle, such as... Figure 11 As shown, when the first plate-shaped connecting rod assembly 6221 and the second plate-shaped connecting rod assembly 6222 are in the first state position, the bearing platform 4 is in the open state, and the first plate-shaped connecting rod assembly 6221 and the second plate-shaped connecting rod assembly 6222 are nearly parallel to the fixed frame 1, i.e., the first preset angle is close to 180°; when in the second state position, the angle between the first plate-shaped connecting rod assembly 6221 and the second plate-shaped connecting rod assembly 6222 and the fixed frame 1 reaches the second preset angle, such as... Figure 12As shown, when the first plate-shaped linkage assembly 6221 and the second plate-shaped linkage assembly 6222 are in the second state position, the supporting platform 4 is in the closed state, and the first plate-shaped linkage assembly 6221 and the second plate-shaped linkage assembly 6222 are nearly perpendicular to the fixed frame 1, i.e., the first preset angle is close to 90°. Through the rotatable connection between the second plate-shaped linkage assembly 6222 and the first plate-shaped linkage assembly 6221, the guardrail 6 is folded within the accommodating space of the fixed frame 1, preventing the risk of escapers falling from the supporting platform 4. Compared to the above-mentioned double-section folding and multi-section folding guardrail structures, the plate-shaped folding structure allows for the installation of more guardrails, and the structure of the plate-shaped linkage assembly is more stable than that of the linkage assembly. For example, the number of the first plate-shaped linkage assembly 6221 and the second plate-shaped linkage assembly 6222 can be set according to actual needs. The states of the first plate-shaped connecting rod assembly 6221 and the second plate-shaped connecting rod assembly 6222 when deployed are as follows: Figure 11 As shown; the folded states of the first plate-shaped link assembly 6221 and the second plate-shaped link assembly 6222 are as follows: Figure 12 As shown.

[0131] In this embodiment, the distance between adjacent support portions 62 located between the handrail portion 61 and the support platform 4 is equal. By making the distance between adjacent support portions 62 between the handrail portion 61 and the support platform 4 equal, the connection structure between the support portion 62 and the handrail portion 61 and the support platform 4 is more stable. The distance between adjacent support portions 62 is set based on preventing escape personnel from falling through the gaps between adjacent support portions 62 and ensuring the stability of the guardrail 6 structure.

[0132] like Figure 13 As shown, the escape platform railing further includes a protective net 102, which is connected to the handrail 61 and the support platform 4, and is disposed between the handrail 61 and the support platform 4; the protective net 102 includes a strip-shaped protective net or a mesh-shaped protective net. Compared with the above-mentioned linkage structure, the protective net 102 can save material costs and reduce the width of the fixing frame 1.

[0133] like Figure 24As shown, the support portion 62 includes at least one ninth link 638 disposed between the handrail portion 61 and the support platform 4, the ninth links 638 being connected to each other by a connecting rope 639; one end of the connecting rope 639 is connected to the handrail portion 61, and the other end is connected to the support platform 4. By configuring the support portion 62 in this way, the rotation shaft 103 is avoided, thus preventing the rotation shaft 103 from causing uneven movement or even jamming when the support platform 4 is retracted into or extended outside the fixed frame 1 due to repeated use. The adjacent links disposed between the handrail portion 61 and the support platform 4 are equidistant.

[0134] like Figure 13 As shown, the escape platform railing further includes: a rotating shaft 103, which is rotatably connected to the supporting platform 4 and disposed on three sides of the supporting platform 4 that are not rotatably connected to the fixed frame 1; when the supporting platform 4 rotates in a first direction, the rotating shaft 103 rotates in a second direction, and the protective net 102 is wrapped around the outside of the rotating shaft 103; when the supporting platform 4 rotates in a third direction, the rotating shaft 103 rotates in a fourth direction, and the protective net 102 is unfolded from the outside of the rotating shaft 103; the first direction is the direction closer to the interior, and the third direction is the direction farther away from the interior; the second direction is opposite to the fourth direction. When the supporting platform 4 rotates from inside the fixed frame 1 to the outdoors via the opening device, the power unit is activated, and the rotating shaft 103 rotates, uniformly unfolding the protective net 102 wrapped around the outside of the rotating shaft 103, thus unfolding it between the handrail 61 and the supporting platform 4. When the supporting platform 4 rotates from inside the fixed frame 1 to the indoors via the closing device, the power unit is activated, and the rotating shaft 103 rotates, wrapping the protective net 102 between the handrail 61 and the supporting platform 4 around the outside of the rotating shaft 103, thus completely wrapping the protective net 102 around the outside of the rotating shaft 103, completing the storage of the protective net, preventing the protective net 102 from being unable to open the supporting platform 4 normally due to being tangled, or causing the protective net 102 to be damaged when the supporting platform 4 is opened next time. The rotating shaft 103 can also be set on the handrail 61, corresponding to the opposite direction of the three sides of the supporting platform 4 that are not rotatably connected to the fixed frame 1.

[0135] The support portion 62 includes at least one plate-shaped guardrail 104 disposed between the handrail portion 61 and the supporting platform 4, the plate-shaped guardrails 104 being connected by a rotating shaft 6211; when the supporting platform 4 rotates along a first direction, the included angle between adjacent plate-shaped guardrails 104 decreases; when the supporting platform 4 rotates along a third direction, the included angle between adjacent plate-shaped guardrails 104 increases. When the supporting platform 4 rotates along the first direction, i.e., when the supporting platform 4 is housed within the fixed frame 1, the plate-shaped guardrails 104 fold together, thereby reducing the included angle between adjacent plate-shaped guardrails 104, such as... Figure 19 As shown; when the supporting platform 4 rotates in the second direction, that is, when the supporting platform 4 opens, the plate-shaped guardrails 104 will unfold relative to each other, thereby increasing the included angle between adjacent plate-shaped guardrails 104, until they are fully unfolded, that is, the plate-shaped guardrails 104 form a plane, as shown. Figure 18 As shown, compared to the above structure, the structure of the plate-shaped guardrail 104 in this embodiment of the application increases the safety of the escapers on the support platform 4, and increases the connection strength between the handrail 61 and the support platform 4.

[0136] like Figure 25 and Figure 26 As shown, the support portion 62 includes: a first sleeve 632, which is connected to the bearing platform 4; an elastic element track 633, which is sleeved inside the first sleeve 632; the elastic element track 633 serves two purposes: firstly, to protect the first sleeve 632 and prevent the elastic element 634 from scratching it; and secondly, to reduce the friction between the elastic element 634 and the elastic element track 633; ​​and an elastic element 634, which is disposed inside the first sleeve 632, with one end of the elastic element 634 connected to the first sleeve 632. The elastic element 634 is connected within the elastic element track 633; ​​a second sleeve 635 is connected on one side to the other end of the elastic element 634, and on the other side to the handrail portion 61; elastic element clips 636 are provided on both sides of the second sleeve 635, the elastic element clips 636 are located in the same horizontal direction, and the elastic element clips 636 are disposed between the first sleeve 632 and the second sleeve 635; wherein, when the distance between the bearing platform 4 and the handrail portion 61 reaches a preset value, the elastic element clips 636 and the release holes 637 provided in the first sleeve 632 achieve self-locking.

[0137] like Figure 27 and Figure 28As shown, the support portion 62 further includes an elastic element 634, which is disposed within the first sleeve 632. One end of the elastic element 634 is connected to the first sleeve 632, and the other end is connected to the second sleeve 635. The elastic element 634 is also connected within the elastic element track 633. The elastic element 634 allows the armrest portion 61 to be unfolded more quickly.

[0138] In this embodiment, at least one sleeve assembly is further provided between the first sleeve 632 and the second sleeve 635; the sleeve assembly closer to the first sleeve 632 is connected to the first sleeve 632, and the sleeve assembly closer to the second sleeve 635 is connected to the second sleeve 635, and the sleeve assemblies are interconnected. It can be understood that by setting multiple sets of sleeves, the length of a single sleeve can be reduced, making it easier to store the support platform 4 within the fixed frame 1. As the distance between the support platform 4 and the handrail 61 gradually increases, the sleeve assemblies provided between the first sleeve 632 and the second sleeve 635 will be pulled up one by one. Each sleeve assembly is engaged with an adjacent sleeve assembly via an elastic clip 636 until the distance between the support platform 4 and the handrail 61 reaches a preset value. The second sleeve 635 then engages with the adjacent sleeve assembly via the elastic clip 636, completing the release of the support platform.

[0139] like Figure 14 and Figure 15 As shown, the escape platform railing further includes a fixing part 101, which is disposed on the fixing frame 1; the fixing part 101 is connected to the end of the handrail part 61 near the fixing frame 1; wherein, when the distance between the supporting platform 4 and the handrail part 61 reaches a preset value, the fixing part 101 and the locking structure provided on the fixing frame 1 achieve self-locking. The function of the fixing part 101 is to prevent escapees on the supporting platform 4 from pressing the upper handrail part 61 of the railing 6, causing the railing 6 to change from an unfolded state to a folded state, thereby causing the escapees to fall from the railing 6.

[0140] In this embodiment, the fixing part 101 includes: a guide part 1011, which is slidably connected to the receiving space of the fixing frame 1; and a locking part 1012, one end of which is connected to the guide part 1011 and the other end of which is connected to the end of the handrail part 61. When the distance between the bearing platform 4 and the handrail part 61 reaches a preset value, the locking part 1012 and the locking structure provided on the fixing frame 1 achieve self-locking. The guide part 1011 is slidably connected to a sliding rod in the receiving space of the fixing frame 1. When the bearing platform 4 does not reach the set position, such as... Figure 14As shown, the locking part 1012 is normally slidably connected between the side wall of the fixed frame 1 and the guide part 1011. At this time, the supporting platform 4 rotates away from the interior; when the supporting platform 4 reaches the set position, as... Figure 15 As shown, when the locking part 1012 reaches the locking structure provided on the fixed frame 1, the locking part 1012 and the locking member of the locking structure provided on the fixed frame 1 achieve self-locking, that is, the handrail part 61 and the guide part 1011 cannot move towards the bearing platform 4, so that the support part 62 will not fold, preventing the escape personnel on the bearing platform 4 from pressing the upper handrail part 61 of the guardrail 6, causing the guardrail 6 to change from the unfolded state to the folded state, thereby causing the escape personnel to fall from the guardrail 6.

[0141] It is worth noting that the guardrail structure in the current technology can also be used as the guardrail structure of this application, so as to realize the function of folding the load-bearing platform 4 and the handrail 61 and storing them in the fixed frame.

[0142] A second aspect of this application provides an escape platform, comprising: a support platform 4 and a fixed frame 1; the fixed frame 1 is disposed within an opening in a building wall, and the support platform 4 is rotatably connected to the fixed frame 1; when the support platform 4 is in a closed state, it is engaged within the fixed frame 1 to seal the opening; when the support platform 4 is in an open state, it moves to the outside of the building wall to form a platform for escaping personnel to rest; the escape platform further comprises: an escape platform railing as described in any of the above embodiments, the escape platform railing being disposed between the support platform 4 and the handrail 61. The effects of the above escape platform embodiments can be found in the above description of the various components and functions of the escape platform, and will not be repeated here.

[0143] The above specific embodiments further illustrate the purpose, technical solution and beneficial effects of this application. It should be understood that the above are only specific embodiments of this application and are not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made on the basis of the technical solution of this application should be included within the scope of protection of this application.
