Description

Technical Field

[0001] The invention belongs to the technical field of refuge evacuation and rescue, and in particular relates to a foldable pedal and an evacuation and rescue platform between refuge floors. Background Art

[0002] As urbanization and modernization continue to advance, urban land is becoming increasingly scarce, and the number and height of high-rise buildings in cities are increasing. Compared with ordinary buildings, once a fire accident occurs, high-rise buildings will lead to a higher fire risk due to the large number of people and electric heating equipment and the longer evacuation time.

[0003] In order to facilitate the trapped persons to enter the evacuation equipment, an evacuation pedal is usually set on the side of the evacuation equipment for the trapped persons to board. The existing evacuation pedal is usually in the form of a straight plate, resulting in the evacuation pedal occupying a large area in daily, non-rescue conditions, which in turn results in a larger overall area occupied by the evacuation equipment. Summary of the invention

[0004] In view of the above analysis, the present invention aims to provide a foldable pedal and an evacuation and rescue platform between refuge floors, so as to solve the problem in the prior art that the evacuation pedal occupies a large area in daily, non-rescue conditions.

[0005] The purpose of the present invention is mainly achieved through the following technical solutions.

[0006] The present invention provides a foldable pedal, comprising a pedal bracket, a first plate body, a second plate body and a telescopic rod, wherein one end of the first plate body is rotatably connected to the pedal bracket, the other end of the first plate body is rotatably connected to the second plate body, and one end of the pedal bracket is rotatably connected to one end of the telescopic rod.

[0007] Further, the foldable step has a vertical mode, an inclined mode and a horizontal mode relative to the mounting surface.

[0008] Further, when the foldable pedal is in the tilting mode or the horizontal mode, the telescopic rod is in an extended state, and the first plate body and the second plate body are located on the same plane;

[0009] When the foldable pedal is in the vertical mode, the telescopic rod is in a retracted state, and the first plate body and the second plate body are both arranged in the vertical direction and overlap each other.

[0010] Furthermore, the telescopic rod is located below the first plate body and the second plate body.

[0011] Furthermore, one end of the pedal bracket and one end of the telescopic rod, the first plate body and the second plate body, and the other end of the telescopic rod and an end of the second plate body away from the first plate body are all rotationally connected through a rotating shaft.

[0012] Furthermore, it also includes a pedal drive motor for driving the telescopic rod to extend and retract.

[0013] Furthermore, it also includes railings arranged on both sides of the first plate body and the second plate body.

[0014] Furthermore, between the multiple refuge layers, in the vertical direction, the opposite surfaces of two adjacent foldable pedals are provided with corresponding signal receivers and signal transmitters.

[0015] Furthermore, the signal receiver is arranged on the lower surface of the foldable pedal located at the top, and the signal transmitter is arranged on the upper surface of the foldable pedal located at the bottom.

[0016] The present invention also provides an inter-layer evacuation and rescue platform, comprising at least one layer of rescue platform units, wherein the rescue platform units comprise a first evacuation pedal and a second evacuation pedal, wherein the first evacuation pedal and the second evacuation pedal are both the above-mentioned foldable pedals.

[0017] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects.

DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0036] Embodiment 1

[0037] This embodiment provides a foldable pedal. Figure 1a to Figure 1c The foldable pedal has a vertical mode, an inclined mode and a horizontal mode relative to a mounting surface (e.g., a horizontal plane), and includes a pedal bracket 11, a first plate body 8, a second plate body 5 and a telescopic rod 7 (e.g., a hydraulic rod). One end of the first plate body 8 is rotatably connected to the pedal bracket 11, and the other end of the first plate body 8 is rotatably connected to the second plate body 5. One end of the pedal bracket 11 is rotatably connected to one end of the telescopic rod 7.

[0038] When the foldable pedal is in the tilt mode or the horizontal mode, the telescopic rod 7 is in an extended state, and the first plate 8 and the second plate 5 are located on the same plane. When the foldable pedal is in the vertical mode, the telescopic rod 7 is in a retracted state, and the first plate 8 and the second plate 5 are both arranged in the vertical direction and overlap.

[0039] Compared with the prior art, the foldable pedal provided in this embodiment, on the one hand, the telescopic rod 7 is rotatably connected to the pedal bracket 11. By changing the angle between the telescopic rod 7 and the pedal bracket 11, the first evacuation pedal and the second evacuation pedal can be switched between the inclined mode and the horizontal mode; on the other hand, by changing the telescopic length, the distance between the pedal bracket 11 and the end of the second plate body 5 away from the first plate body 8 can be changed. In order to adapt to the change in distance, the first plate body 8 and the second plate body 5 are rotated, so that it is possible to switch between the vertical mode and the inclined mode or between the vertical mode and the horizontal mode.

[0040] At the same time, in daily, non-rescue conditions, since the telescopic rod 7 is in a retracted state, the first plate body and the second plate body are both arranged in the vertical direction and overlap, thereby effectively reducing the occupied area of ​​the foldable pedal.

[0041] In order to facilitate the telescopic rod 7 to drive the first plate body 8 and the second plate body 5 to rotate, the telescopic rod 7 is located below the first plate body 8 and the second plate body 5 .

[0042] Exemplarily, one end of the pedal bracket 11 and one end of the telescopic rod 7 , between the first plate 8 and the second plate 5 , and between the other end of the telescopic rod 7 and one end of the second plate 5 away from the first plate 8 are all rotatably connected via the rotating shaft 4 .

[0043] It is understandable that, in order to realize automatic extension and retraction of the telescopic rod 7 , the foldable pedal further comprises a pedal driving motor for driving the telescopic rod 7 to extend and retract.

[0044] In order to improve the evacuation safety of the foldable pedal, the above-mentioned foldable pedal also includes a railing 1 arranged on both sides of the first plate body 8 and the second plate body 5. Through the setting of the railing 1, it can be ensured that the trapped persons will not fall from the foldable pedal when passing through the foldable pedal, thereby improving the evacuation safety of the foldable pedal.

[0045] In order to be able to determine whether the foldable pedal is switched to the horizontal mode, between the multi-layer refuge layers, in the vertical direction, the surfaces of the two adjacent foldable pedals facing each other (i.e., the lower surface of the foldable pedal located above and the upper surface of the foldable pedal located below) are provided with corresponding signal receivers 2 and signal transmitters 9. For example, from the perspective of control, the signal receiver 2 is provided on the lower surface of the foldable pedal located above, and the signal transmitter 9 is provided on the upper surface of the foldable pedal located below. In this way, when the two adjacent foldable pedals are not fully unfolded to the horizontal state, the signal receiver 2 cannot receive the signal transmitted by the signal transmitter 9. Once the two adjacent foldable pedals are fully unfolded, the signal receiver 2 is located on the signal path of the signal transmitter 9, so that it can receive the signal transmitted by the signal transmitter 9, indicating that the two adjacent foldable pedals are both in the horizontal mode.

[0046] Embodiment 2

[0047] This embodiment provides an evacuation and rescue platform between refuge floors. Figures 2 to 4b , including at least one rescue platform unit, the rescue platform unit includes a first evacuation pedal and a second evacuation pedal, the structures of the first evacuation pedal and the second evacuation pedal are basically the same, and the first evacuation pedal and the second evacuation pedal are the foldable pedals provided in Example 1.

[0048] Compared with the prior art, the beneficial effects of the refuge inter-layer evacuation and rescue platform provided in this embodiment are substantially the same as the beneficial effects of the foldable pedal provided in the first embodiment, and are not described in detail here.

[0049] Exemplarily, the above-mentioned rescue platform unit also includes a mobile base, a pod and a rotating boom, the bottom end of the rotating boom is rotatably connected to the mobile base, one end of the pedal bracket 11 is fixedly connected to the mobile base, the pod is suspended below the top of the rotating boom and is placed on the mobile base, the first evacuation pedal is located on one side of the mobile base and is rotatably connected to the mobile base, and the second evacuation pedal is located on the other side of the mobile base and is rotatably connected to the mobile base.

[0050] Specifically, the rescue platform unit has daily mode, login mode and detachment mode. When the rescue platform unit is in daily mode, the first evacuation pedal and the second evacuation pedal are both in vertical mode, and the pod is located at the center of the mobile base; when the rescue platform unit is in login mode, the first evacuation pedal is in inclined mode, serving as a login pedal for personnel, the second evacuation pedal is still in vertical mode, the pod is located at the center of the mobile base, and the entrance of the pod is in an open state; when the rescue platform unit is in detachment mode, the first evacuation pedal is in inclined mode, serving as a login pedal for personnel, the second evacuation pedal is in horizontal mode, serving as a detachment pedal for personnel, the entrance of the pod is in a closed state, and the pod is moved to the side of the second evacuation pedal by rotating the boom and is suspended in the air.

[0051] For high-rise buildings, there are many people. When a fire occurs, it takes a long time for people to evacuate, and it is difficult to ensure that people can be evacuated safely in a short time. In order to avoid casualties, when the height of a public building exceeds 100 meters, a refuge floor and refuge space should be set up. The refuge floor refers to the temporary refuge floor used by people in the building when a fire breaks out in a high-rise building. It is used to meet the needs of temporary refuge for evacuated people and wait for fire fighting and rescue. Therefore, for high-rise buildings, the existence of the refuge floor can buy a lot of time for fire fighting and rescue, but in traditional high-rise buildings, the refuge floor, as a temporary refuge method, can only increase the rescue time of people, but cannot guarantee that the safety of people's lives is not threatened.

[0052] Compared with the prior art, the inter-refuge floor evacuation and rescue platform provided in this embodiment is a rescue platform that is placed in advance at each refuge floor of a high-rise building. It is an evacuation platform for trapped people in the refuge floors to move between refuge floors. It can solve the problems of long vertical evacuation distances, high risks in the evacuation process, and difficulties in evacuating people during fires in high-rise buildings, as well as facilitate the transportation of materials and firefighting and rescue equipment required by personnel, providing the necessary conditions for firefighting and rescue personnel to carry out firefighting and rescue operations in high-rise buildings.

[0053] The structure of the rotating boom includes a mechanical arm 15, a rotating seat 18, a chain 20 and a drum 13, see Figure 5 The rotating seat 18 is arranged on the mobile base, one end of the mechanical arm 15 is rotatably connected to the mobile base through the rotating seat 18, the drum 13 is arranged at the other end of the mechanical arm 15, one end of the chain 20 is coiled on the drum 13, and the other end is fixedly connected to the pod, and the pod is suspended under the mechanical arm 15 by the chain 20. By rotating the rotating seat 18, the pod can be moved from the mobile base to the side of the second evacuation pedal.

[0054] Exemplarily, the mechanical arm 15 includes an inclined arm and a horizontal arm, the lower end of the inclined arm is fixedly connected to the rotating seat 18, the upper end of the inclined arm is fixedly connected to the horizontal arm, and the reel 13 is arranged below the horizontal arm.

[0055] Taking into account that the mechanical arm 15 needs to withstand very large forces in the process of lifting the trapped persons, in order to ensure the supporting stability of the mechanical arm 15, the above-mentioned rotating boom also includes a support rod 16 (for example, a hydraulic rod), one end of the support rod 16 is fixedly connected to the rotating seat 18, and the other end of the support rod 16 is fixedly connected to the tilting arm. The cross-sectional shape formed by part of the tilting arm, the support rod 16 and part of the rotating seat 18 is a triangle. The support rod 16 can effectively improve the supporting stability of the mechanical arm 15.

[0056] During the lifting process of the pod, the mechanical arm 15 will undergo a large rotational displacement. In order to remind personnel that the pod is in the process of being lifted, the above-mentioned rotating boom also includes a boom indicator light 14 arranged on the horizontal arm. When the above-mentioned rescue platform unit is in the lifting mode, the boom indicator light 14 is in an on state, thereby reminding personnel that the pod is in the process of being lifted, thereby further improving the evacuation and rescue safety of the above-mentioned refuge floor evacuation and rescue platform; in addition, the boom indicator light 14 can also be used as a boom lighting lamp to provide lighting for trapped personnel.

[0057] It can be understood that, in order to be able to drive the rotating seat 18 to rotate, the above-mentioned rotating boom also includes a boom driving motor 17 for driving the rotating seat 18 to rotate and a boom power supply for supplying power to the boom driving motor 17 .

[0058] The structure of the pod includes a pod body 25 and a locking hook 22 disposed on the upper surface of the pod body 25. Figure 6 The hook lock 21 at the lower end of the chain 20 of the rotating boom is fixedly connected to the lock hook 22.

[0059] Similarly, in order to remind personnel that the pod is in the process of being lifted off, the pod also includes a pod indicator light 24 provided on the pod body 25. When the rescue platform unit is in the lifting mode, the pod indicator light 24 is in the on state, thereby reminding personnel that the pod is in the process of being lifted off, thereby further improving the evacuation and rescue safety of the above-mentioned refuge floor evacuation and rescue platform; in addition, the pod indicator light 24 can also be used as a pod lighting lamp to provide lighting for trapped personnel.

[0060] Taking into account that when the rescue platform unit is in the lifting mode, the pod needs to be lifted from the rescue platform unit on the upper layer to the rescue platform unit on the lower layer, in order to reduce the shaking of the pod during the lifting process, the first evacuation pedal and the second evacuation pedal respectively also include pedal hooks 3 arranged on both sides of the first plate 8 and / or the second plate 5, the rotating boom includes a guide rope 19 and an boom hook 12 arranged on the mechanical arm 15, the pod is provided with a cabin hook 23 on the cabin body 25, one end of the guide rope 19 is fixedly connected to the boom hook 12, and the other end passes through the pod hook on the pod on the upper layer and the pedal hook 3 on the lower layer in sequence, and is fixedly connected to the pedal hook 3, so that the pod can be guided during the lifting process and the shaking of the pod can be reduced.

[0061] The structure of the mobile base includes a bottom plate 26 and a mobile wheel 28 (eg, a wheel) and / or a support seat 29 disposed on the lower surface of the bottom plate 26, see Figure 7 In this way, when the rescue platform unit needs to be moved, the support seat 29 is retracted, and the rescue platform unit is moved by rotating the moving wheel 28. When evacuating and rescuing, the support seat 29 supports the bottom plate 26, so that a fixed connection between the bottom plate 26 and the mounting surface can be achieved.

[0062] When the first evacuation pedal and the second evacuation pedal are in a vertical mode or a horizontal mode relative to the mobile base, in order to facilitate operators to climb onto the base plate 26 for maintenance and other work, the mobile base also includes a pedal 27 provided on at least one side of the base plate 26. Operators can climb onto the base plate 26 for maintenance and other work by stepping on the pedal 27 without using the first evacuation pedal and the second evacuation pedal.

[0063] It is worth noting that when the rescue platform unit is moved, the cabin 25 may fall down due to the high height of the cabin 25. Therefore, the cabin 25 is a sandwich structure. Figure 8, including an inner layer 251 and an outer layer 252 located outside the inner layer 251, with a gap between the inner layer 251 and the outer layer 252, the inner wall of the outer layer 252 (i.e. the side wall facing the inner layer 251) is provided with a plurality of protrusions 6, along the direction gradually away from the outer layer 252, the lower surface of the groove between two adjacent protrusions 6 (i.e. the upper surface of the protrusion 6 located below) is inclined upward, and a center of gravity adjusting ball 10 is arranged in the groove, and a channel is provided between the side wall of the protrusion 6 facing the inner layer 251 and the outer wall of the inner layer 251, and the center of gravity adjusting ball 10 detaches from the groove and falls into the bottom of the channel. During implementation, taking the case where the cabin 25 tips over in a clockwise direction as an example, when the cabin 25 tips over in a clockwise direction, the lower surface of the groove will rotate clockwise accordingly, causing the lower surface of the groove to change from tilting upward to tilting downward. Once the lower surface of the groove tilts downward, the center of gravity adjusting ball 10 will detach from the groove and fall to the bottom of the channel, causing the center of gravity of the left side of the cabin 25 to lower, thereby reducing the chance of the cabin 25 tipping over.

[0064] Exemplarily, the inter-layer evacuation and rescue method using the above-mentioned inter-layer evacuation and rescue platform includes the following steps:

[0065] Step 1: The control center receives the fire alarm signal and switches the evacuation and rescue platform from daily mode to login mode;

[0066] Step 2: The pod indicator light 24 is turned on, and the professionals at the platform guide the trapped personnel to board the mobile base in an orderly manner through the personnel boarding pedal (i.e., the first evacuation pedal). At the same time, the control center sends a trapped personnel signal to the pod;

[0067] Step 3: The entrance of the pod is opened and the trapped persons enter the pod;

[0068] Step 4: After all trapped persons have entered the gondola, the professionals at the platform provide manual feedback to the control center and send a start transfer signal to the control center. After receiving the start transfer signal, the control center confirms that the escape transfer can begin at this time, and the professionals at the control center manually press the escape button and send a hoisting signal to the control center;

[0069] Step 5: According to the adjustment signal, the evacuation and rescue platform is switched from the landing mode to the lifting mode, and the personnel lifting pedal (i.e., the second transport pedal) is switched from the vertical mode to the horizontal mode, and the telescopic rod 7 is then extended. Since the telescopic rod 7 is connected to the second plate body 5, the telescopic rod 7 will drive the second plate body 5 to rotate counterclockwise around the rotation axis 4 of the pedal bracket 11. The second plate body 5 is connected to the first plate body 8 through the rotation axis 4, and the second plate body 5 will drive the first plate body 8 to rotate clockwise until the first plate body 8 and the second plate body 5 become a plane and parallel to the ground, completing the switching of the second transport pedal from the vertical mode to the horizontal mode. After the switching is completed, the personnel lifting pedal feeds back the switching completion signal to the control center through the corresponding signal transmitter 9 and signal receiver 2;

[0070] Step 6: The control center sends a lifting signal to the rotating boom controller. The rotating boom controller controls the boom indicator light 14 on the horizontal arm to turn on according to the lifting signal. At the same time, the rotating boom controller sends a retraction signal to the chain controller. After receiving the retraction signal, the chain controller controls the chain 20 to retract upward, so that the pod moves upward, lifts the pod to the specified position, and sends a lifting completion signal to the rotating boom controller through the chain controller. The rotating boom controller receives the lifting completion signal and believes that the pod has reached the specified height at this time, and sends a rotation signal to the rotating seat controller;

[0071] It should be noted that, after the chain controller receives the retraction signal and controls the chain 20 to retract upward, considering that after the pod translates upward, the pulling torque caused by the gravity of the pod acting on the lower end of the rotating boom changes, the rotating boom controller sends a support signal to the support rod controller, and the support rod 16 changes the upward support force of the mechanical arm 15 according to the support signal, so that the entire rotating boom can continue to remain relatively still;

[0072] Step 7: The rotating seat controller controls the rotating seat 18 to rotate 90° counterclockwise according to the rotation signal, and drives the pod to rotate to the side where the personnel are suspended from the pedal and the entrance of the pod faces the personnel suspension pedal, and sends a signal that the evacuation of the current floor is completed to the control center;

[0073] Step 8: The control center receives the evacuation completion signal of the current floor, and the professionals at the control center manually feed back to the professionals at the platform. The professionals at the platform sequentially pass the guide rope 19 on the rotating boom through the cabin hook 23 on the pod on the upper floor and the pedal hook 3 on the lower floor, and fix them with the pedal hook 3, and send a connection completion signal to the control center;

[0074] Step 9: The control center receives the connection completion signal and sends a descending signal to the rotating boom. The rotating boom drives the pod to descend to the rescue platform unit on the next level according to the descending signal.

[0075] Step 10: Determine whether the refuge floor on the next level is safe. If it is safe, complete the evacuation and rescue of trapped personnel;

[0076] If it is unsafe, professionals at the platform will guide the trapped people in the cabin to the cabin on the next floor for lifting.

[0077] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
