DETAILED DESCRIPTION

[0058] The present application provides an escape platform guardrail lifting device and an escape platform to solve the technical problem that the guardrail device provided on the current escape platform cannot realize automatic lifting function, and there is no suitable fixing tool, which leads to the fact that the guardrail device is not very firm after being unfolded, and further leads to the fact that the escape personnel has a great safety risk when on the escape platform.

[0059] The escape platform is arranged on each floor of a building to form a platform structure on the surface of the outer wall of the building when opened in case of danger. The existing building is usually provided with horizontally opened, sliding, top-hung and bottom-hung windows for lighting and ventilation, but the opening sash of the window is small, the opening area is small, and the platform for gathering people cannot be formed after opening, which greatly reduces the escape probability of the trapped person.

[0060] The escape platform provided in the application can be arranged at a position convenient for escape on each floor of a building, and the platform can be used as a part of the building when closed, and can be used to realize the functions of lighting, ventilation and smoke exhaust of the window; when opened, the platform can be formed on the outer facade of the building, has a certain bearing capacity, and the escape personnel can gather on the platform to wait for rescue or use the slow descent device to descend to a safe position to escape from danger.

[0061] As Figures 1 to 7 The escape platform provided in the embodiment of the application is installed on the opening of the building, and the position of the escape platform needs to be ensured to meet the facade effect requirements of the building. The escape platform comprises a bearing platform 4 and a fixed frame 1, the fixed frame 1 is arranged on the opening of the wall of the building, the bearing platform 4 is movably connected with the fixed frame 1, a manual switch 2 is arranged on the side of the fixed frame 1 in the room, the manual switch 2 is provided with a protection structure 21, the manual switch 2 is sealed in the protection structure 21 in the normal case to avoid being accidentally touched, and when used, the protection structure 21 is opened or removed, and then the manual switch 2 can be operated.

[0062] A first sealing body 41 is arranged in the four surrounding frames of the bearing platform 4, the first sealing body 41 is extruded and sealed with a second sealing body 12 arranged on the inner side of the fixed frame 1 when the bearing platform 4 is in the closed state, a guardrail 6 is arranged on the bearing platform 4, the guardrail 6 is arranged at the edge of the bearing platform 4, and is hidden in a foldable manner in a first containing space 111 of two side frames 11 of the fixed frame 1 and a second containing space 112 of the upper frame of the fixed frame.

[0063] A cable-stayed component 5 is 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 component 5 is hidden in the first containing space 111 of the two side frames 11 of the fixed frame 1; a first locking part 42 is arranged on the frame of the bearing platform 4, and the first locking part 42 forms a locking state with a second locking part 13 arranged on the frame of the fixed frame.

[0064] When 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 to open to a set position and stop outside the room, and the connection and rotation can be realized by the hinged structure 131. When the bearing platform 4 is in the open state, the personnel need to gather on the bearing platform 4 when escaping, and the bearing platform 4 should have a certain bearing capacity.

[0065] In order to ensure the safety of the escaping personnel, 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 the bearing platform 4 is to bear. Therefore, the inclined pulling component 5 connected with the bearing platform 4 is arranged on both sides of the fixed frame 1 after the bearing platform 4 is opened, so as to enhance the bearing strength of the bearing platform 4.

[0066] The inclined pulling component 5 can be a rod structure and is provided with a limiting device. When the bearing platform 4 is restored to the closed state, the inclined pulling component 5 is enabled to run to a specified direction and is located in the first containing space of the bearing platform 4 or the fixed frame 1. The inclined pulling component 5 can also be a telescopic component. When the bearing platform 4 is opened, the telescopic component is stretched or contracted to a set position. When the bearing platform 4 is restored to the closed state, the telescopic component is located in the containing space of the bearing platform 4 or the fixed frame 1. The inclined pulling component 5 can also be a rope or chain component. When the bearing platform 4 is in the open state, the rope or chain component is stretched to a set position and stops running. One end of the rope or chain component can be provided with a counterweight structure or a friction structure, so that the bearing platform 4 is slowly opened.

[0067] At this time, the bearing platform 4 has the escape function. In order to ensure that the escaping personnel on the bearing platform 4 do not have the risk of falling, the side edge of the bearing platform 4 not connected with the wall can be provided with a safety guardrail 6 when the bearing platform 4 is in the open state. When the bearing platform 4 is opened, the guardrail 6 is automatically raised 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 is raised to a set height and is locked. A gap for the escaping personnel to use is arranged at the position of the guardrail of the bearing platform. After wearing the escape equipment, the escaping personnel can safely escape through the gap without climbing over the guardrail to escape. The number and position of the gap can be set according to the use.

[0068] The fixed frame 1 is further provided with a connecting part 8 of the backpack type slow descent device. The escape personnel wear the escape backpack, the slow descent rope of the backpack type slow descent device is connected with the connecting part 8, and the lifting of the backpack type slow descent device is realized through the slow descent rope. Specifically, after the escape personnel wear the backpack type slow descent device, the connecting end of the slow descent rope is connected with the connecting end of the connecting part 8. In the actual use process, the backpack type slow descent device realizes slow descent under a certain gravity through the friction part. The slow descent rope is stored in the winch connected with the friction part. The whole component is installed in the backpack. The connecting end of the slow descent rope extends out of the backpack and is connected with the connecting part 8 provided on the fixed frame 1. After the escape personnel fix the backpack type slow descent device on the body through the safety belt, the escape can be realized. The friction of the friction part can be adjusted. The adjustment of the friction can change the descending speed. The backpack type slow descent device can be provided with a descending stopping device. The descending stopping device can be manually controlled. The descending stopping device can extrude the friction part through the extrusion structure to increase the friction. When the friction is greater than the gravity, the descending is stopped. The descending stopping device can also extrude the slow descent rope through the extrusion structure to increase the friction. When the friction is greater than the gravity, the descending is stopped.

[0069] The escape platform is further provided with a recovery device 3. The recovery device 3 is arranged on the fixed frame 1. After the bearing platform 4 is opened to complete the escape task, the functions and components of the bearing platform 4 are checked. In the case that the functions and components of the bearing platform 4 are not damaged, the recovery device 3 can be used to manually recover the bearing platform 4 to the closed state from the indoor side. The locking is realized through the locking structure arranged on the fixed frame 1 and the bearing platform 4. After the bearing platform 4 is recovered to the initial state, the bearing platform 4 can still be repeatedly used.

[0070] Specifically, a rope type component can be used to connect the recovery device 3 and the bearing platform 4. That is, one end of the rope type component is connected with the bearing platform 4, and the other end is connected with the rope wheel of the recovery device 3. The rope wheel is controlled through the one-way movement principle of the pawl. That is, the rope wheel is rotated by using the tool corresponding to the pawl, so that the rope type component is wound on the rope wheel, and the bearing platform 4 is pulled to recover to the initial state. A chain type component can also be used. The chain is matched with the sprocket. The chain is retracted by rotating the sprocket. The retracted chain enters the accommodation space arranged therein, and the bearing platform 4 is pulled to recover to the initial state and realize locking. A screw structure can also be used to realize recovery. The nut connected with the screw rod moves linearly by rotating the screw rod. The nut rope type component, chain component or connecting rod component is linked with the escape platform. The nut moves in the set direction to recover the escape platform to the initial state and realize locking.

[0071] The escape platform can also be provided with a slow descent device 7, and the escape is realized through the slow descent device 7. When in use, the escape personnel need to wear an escape safety harness, and after wearing the safety harness, the safety harness is connected to the slow descent cable 71 of the slow descent device 7, and the escape personnel can be slowly descended to a safe position or the ground to escape; the slow descent device 7 is arranged on the indoor side wall, and the number thereof can be set to be multiple, and the connection end for connecting the safety harness worn by the escape personnel is arranged to protrude outside the room, so that the escape personnel can be connected to the connection end of the slow descent device after wearing the safety harness, and quickly escape. The slow descent device 7 can also be arranged on the fixed frame 1, and the number thereof can be set to be multiple, and the connection end 72 of the slow descent device 7 arranged on the fixed frame 1 also protrudes outside the room, so as to facilitate the escape personnel to quickly escape.

[0072] The 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 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 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 is connected to the connection end 72 of the slow descent device. It should be noted that the number of the above-mentioned first connecting part and the third locking part is set to be 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, but only one pair of first connecting part and third locking part is needed for one escape or one escape personnel. The multiple first connecting parts and third locking parts are 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 slow descent device 7 can also be arranged as a reciprocating running structure, for example, each 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 a safe position or the ground, and then takes off the escape harness. At this time, the second escape personnel on the bearing platform 4 can use the other second connecting part to descend. When the second escape personnel descends, the connection 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, and only the escape harness needs to be worn to quickly escape from the dangerous environment.

[0074] The escape platform can also be provided with a fireproof heat insulation curtain 9 arranged on the indoor side of the upper frame of the fixed frame 1, and the guide part of the fireproof heat insulation curtain 9 is arranged on the indoor side of the side frame 11 of the fixed frame 1. After the escape personnel reach the bearing platform 4, the fireproof heat insulation curtain 9 can be manually pulled down, so as to form a partition seal between the bearing platform 4 and the indoor side of the building. At this time, if there are still personnel who have not escaped to the bearing platform 4 in the room, the fireproof heat insulation curtain 9 can also be opened 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, so as to gain more escape time.

[0075] The fireproof heat insulation curtain 9 is rotated and contracted under the shaft of the accommodating 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 parts. When the heat insulation curtain reaches 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 personnel who have not escaped to the escape platform can continue to hide and escape.

[0076] It should be noted that the 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. It can also be used in other scenes with height difference, such as tower cranes, mountains, bridges, mines or ships.

[0077] Based on the escape platform described above, the specific structure of the fixed frame 1 will be described in detail as follows:

[0078] Referring to Figures 8 to 12 The present application provides a kind of escape platform fixed frame, i.e. the fixed frame 1 described in the foregoing, specifically includes:
