DETAILED DESCRIPTION

[0047] The application provides an escape platform guardrail lifting device and an escape platform to solve the technical problem that the guardrail device provided on the escape platform cannot realize automatic lifting function, and no suitable fixing tool leads to the fact that the guardrail device is not firm after being unfolded, and thus a great safety hazard exists when an escape personnel is on the escape platform.

[0048] Illustratively, the escape platform is provided for forming a platform structure for escaping on the surface of the building outer wall after being opened when a dangerous situation occurs. The existing building is usually provided with casement, 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 personnel gathering cannot be formed after being opened, which greatly reduces the escape probability of the trapped person.

[0049] The escape platform provided in the application can be arranged at a position convenient for escaping on each floor of the building, and the platform can be used as a part of the building when being closed, and can be used to realize the functions of lighting, ventilation and smoke exhaust of the window; when being opened, the platform can be formed on the building facade, 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.

[0050] 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 is ensured to meet the requirements of the facade effect 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 facade 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 being used, the protection structure 21 is opened or removed, and then the manual switch 2 can be operated.

[0051] 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 position of the bearing platform 4, and is hidden in a first containing space 111 of two side frames 11 of the fixed frame 1 in a foldable manner, and is hidden in a second containing space 112 of the upper frame of the fixed frame in a foldable manner.

[0052] 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.

[0053] 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. Specifically, the connection and rotation can be achieved 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.

[0054] 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 set 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, the inclined pulling component 5 connected with the bearing platform 4 is arranged on both sides of the fixed frame 1 to enhance the bearing strength of the bearing platform 4.

[0055] The inclined pulling component 5 can be a rod structure and is provided with a limiting device. When the bearing platform 4 returns to the closed state, the inclined pulling component 5 is enabled to run in 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 returns 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 to enable the bearing platform 4 to be slowly opened.

[0056] At this time, the bearing platform 4 has the escape function. However, 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 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.

[0057] 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.

[0058] 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, and 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.

[0059] 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 lock.

[0060] 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 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 quickly escape after the safety harness is connected to the connection end of the slow descent device.

[0061] The slow descent device 7 can also be arranged on the fixed frame 1, and the number thereof can 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.

[0062] 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 with 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 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 one escape or one escape personnel only needs to use a pair of first connecting part and third locking part. 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.

[0063] 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 the escape personnel only need to wear the escape harness to quickly escape from the dangerous environment.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] Based on the escape platform described above, the specific structure of the escape platform hole reinforcing device will be described in detail as follows:

[0068] Referring to Figures 8 to 10 The escape platform hole reinforcing device provided by the present application specifically comprises:

[0069] The first aspect of the application provides a kind of escape platform hole mouth reinforcing device, it is applied to including bearing platform 4 and fixed frame 1 of escape platform, the bearing platform 4 is rotationally connected in the fixed frame 1;The fixed frame 1 is arranged in the hole mouth of building facade opening;Including: the pre-buried part 100 being arranged in the four around of the hole mouth of building facade;The pre-buried part 100 includes but is not limited to steel plate, steel mesh, steel pipe, steel bar, angle steel, channel steel;The additional frame part 200 being arranged in the outside of the four around of the hole mouth of building facade;The additional frame part 200 includes but is not limited to steel plate, steel pipe, angle steel, channel steel;The additional frame part 200 can be used to reduce the shear force that fixed frame 1 and hole mouth fixed component bear when bearing platform 4 opens;The fixed frame 1 is connected with the pre-buried part 100, additional frame part 200 by fixed part 300.The fixed part 300 includes but is not limited to expansion bolt, bolt, screw.The pre-buried part 100 is pre-buried in the four around of the hole mouth of building facade, the additional frame part 200 is arranged in the outside of the four around of the hole mouth of building facade and is fixedly connected with the pre-buried part 100, fixed frame 1 by the fixed part 300, to strengthen the connection strength between the fixed frame 1 and the building facade, in turn, the connection strength of bearing platform 4 is enhanced, when the personnel stranded in escape is realized to bearing platform 4, bearing platform 4 has certain bearing capacity and stability, and bearing platform 4 can still keep stable in the weather of larger wind force.The one side of additional frame part 200 is connected with the pre-buried part 100 by the fixed part 300, and the other side is arranged in the four around of the hole mouth of building facade and is close to the side of indoor.Exemplarily, the additional frame part 200 can be L-shaped structure, and one side is arranged in the four around of the hole mouth of building facade and is close to the side of indoor, to reduce the shear force that fixed frame 1 and hole mouth fixed component bear when bearing platform 4 opens, to further improve the stability between the fixed frame 1 and the building facade.

[0070] By Figure 8 It can be known that, if the building facade is a concrete structure, the pre-buried part 100 includes: a first pre-buried piece 101, the first pre-buried piece 101 is connected with the additional frame part 200 by the fixed part 300;A second pre-buried piece 102 is connected with the first pre-buried piece 101 and is arranged on the side away from the additional frame part 200.The pre-buried part includes but is not limited to steel plate, steel mesh, steel pipe steel bar, angle steel, channel steel, tie steel bar.Exemplarily, the second pre-buried piece 102 can be J-shaped structure, and the end of vertical structure is connected with the first pre-buried piece 101, and the end of bending structure is arranged on the side away from the first pre-buried piece 101, and the structure of the second pre-buried piece 102 can further improve the stability between the fixed frame 1 and the building facade.

[0071] By Figure 9If the building facade is a brick structure, the device further comprises a concrete layer 400 arranged outside the building facade opening, and the embedded part 100 is arranged in the concrete layer 400. The embedded part includes but is not limited to steel plate, steel mesh, steel pipe reinforcement, angle steel, channel steel, and tie reinforcement. Since the brick structure is made of a plurality of brick materials, the embedded part 100 is not very stable when embedded in the brick structure. Therefore, in the embodiment of the present application, the concrete layer 400 is arranged outside the building facade opening, and the embedded part 100 is arranged in the concrete layer 400. Then, the fixing part 300 is connected with the fixed frame 1 and the attached frame part 200, thereby improving the stability between the fixed frame 1 and the building facade.

[0072] By Figure 9 If the building facade is a brick structure, the embedded part 100 comprises a third embedded part 103 having a first side and a second side parallel to each other, and a third side connected with the same side of the first side and the second side. At least one fourth embedded part 104 is connected with the first side at one end and penetrates the building facade and the second side at the other end. Based on the above structure, the third embedded part 103 is further arranged to connect the concrete layer 400 with the building facade of the brick structure, thereby further improving the stability between the fixed frame 1 and the building facade.

[0073] By Figure 9 If the building facade is a brick structure, one side of the attached frame part 200 is arranged near the fixed frame 1 of the concrete layer 400, and the other side is arranged near the indoor side of the building facade opening. Since the concrete layer 400 is arranged in the brick structure, one side of the attached frame part 200 is arranged near the fixed frame 1 of the concrete layer 400 in the embodiment of the present application, thereby further reducing the shear force on the fixed frame 1 and the opening fixing part.

[0074] By Figure 9It can be seen that if the building facade is a brick structure, the fixed part 300 is sequentially penetrated through the fixed frame 1, the attached frame part 200, the third embedded part 103, the fourth embedded part 104, and the building facade, so that the fixed frame 1 is connected with the embedded part 100 and the attached frame part 200. In the embodiment of the application, the fixed part 300 is sequentially penetrated through the fixed frame 1, the attached frame part 200, the third embedded part 103, the fourth embedded part 104, and the building facade, so that the fixed frame 1 is connected with the embedded part 100, the attached frame part 200, and the concrete layer 400, thereby further improving the stability between the fixed frame 1 and the building facade and making the structure more stable.

[0075] By Figure 10 It can be seen that if the building facade is a curtain wall structure, the embedded part 100 is a rectangular structure, and the embedded part 100 is connected with the columns or beams around the opening of the building facade. If the curtain wall structure of the building facade is an aluminum alloy structure, a steel square tube should be arranged in the aluminum alloy column and beam and connected with the building. The embedded part 100 includes but is not limited to steel plates, steel plates, steel pipes, angle steels, channel steels, and other steel materials, and is embedded in the curtain wall beam and column. The embedded part 100 is used to reinforce the curtain wall opening to enhance the connection strength between the fixed frame 1 of the escape platform and the reinforcing device. Since the building facade is a curtain wall structure, the curtain wall is the outer wall enclosure of the building and does not have bearing capacity. The curtain wall column and beam are the bearing structure of the curtain wall. Therefore, in the embodiment of the application, the curtain wall column and beam are connected with the building through the steel square tube, thereby providing a support bearing structure for the escape platform opening reinforcing device. The fixed part 300 is sequentially penetrated through the fixed frame 1, the attached frame part 200, the embedded part 100, and the building facade, so that the fixed frame 1 is connected with the embedded part 100 and the attached frame part 200.

[0076] By Figure 10 It can be seen that if the building facade is a curtain wall structure, the attached frame part 200 is arranged between the columns or the beams, one side is arranged on the side of the embedded part close to the fixed frame, and the other side is arranged on the side of the building facade opening close to the indoor side. The attached frame part 200 can be an L-shaped structure, one side is arranged on the side of the embedded part close to the fixed frame, and the other side is arranged on the side of the building facade opening close to the indoor side, which is used to reduce the shear force of the fixed frame 1 and the opening fixing part when the bearing platform 4 is opened, thereby further improving the stability between the fixed frame 1 and the building facade.
