Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0035] The connection part can be movably arranged on one side or both sides of the track beam on which the suspended sky train runs, and can be moved to a specified position of the track beam.

[0036] In order to more clearly describe the large-span bridge suspended sky train evacuation platform of the present application, a preferred embodiment of the present application will be described in detail below in conjunction with the drawings.

[0037] As a preferred embodiment of the present application, the large-span bridge suspended sky train evacuation platform of the present application comprises a bearing part and a connection part; the bearing part is installed on the connection part; the bearing part can be connected with the suspended sky train, and is used for passengers to get on / off the suspended train; the connection part is fixedly installed on one side or both sides of the track beam on which the suspended sky train runs, and extends along the length direction of the track beam; or the connection part can be movably arranged on one side or both sides of the track beam on which the suspended sky train runs, and can be moved to a specified position of the track beam. The installation environment of the evacuation platform in the embodiment is mainly a large-span bridge, and those skilled in the art can also install the present application to other column-free installation environments such as tunnels.

[0038] As Figure 1As shown in the drawings, in some preferred embodiments, the evacuation platform of the present application is installed under a large-span bridge, when the suspended air train is a double-track rail, the connecting part 100 is installed between the two adjacent track beams 400; the bearing part 200 includes a first bearing part 210 and a second bearing part 220, the first bearing part 210 and the second bearing part 220 are respectively arranged on the left and right sides of the connecting part 100, and are respectively used for interfacing with the double-track rail beam 400. When it is a single-track rail, the connecting part 100 is installed on one side or both sides of the track beam 400; one end of the bearing part 200 is installed on the connecting part 100, and the other end is used for interfacing with the suspended air train 500.

[0039] As shown in the drawings, Figure 3 In some preferred embodiments, the connecting part 100 includes a first connecting part 110 and a second connecting part 120, the first connecting part 110 and the second connecting part 120 are respectively installed on both sides of the track beam;

[0040] The two ends of the bearing part 200 are respectively installed on the lower part of the suspended air train through the first connecting part 110 and the second connecting part 120, and the bearing part 200, the first connecting part 110 and the second connecting part 120 form an evacuation space. Because there is a distance between the evacuation platform and the suspended air train 500, passengers need a passage to enter the evacuation space, and the passage in this embodiment is preferably arranged on the suspended air train 500. The passage for entering the evacuation platform in this embodiment is preferably a folding evacuation ladder. The evacuation ladder can be arranged inside the evacuation space, when an emergency occurs, the folding evacuation ladder on the suspended air train 500 is opened and placed in a safe position of the bearing part 200, one end of the evacuation ladder is connected with the escape door of the suspended air train 500, and the other end can be connected with the bearing part 200, so as to evacuate passengers. When the evacuation ladder is not needed, the evacuation ladder is folded for storage, which saves the space of the air train carriage. The evacuation passage can also be a fireproof inflatable slide or a traction climbing rope, and the person skilled in the art can flexibly select the evacuation passage according to the actual situation, which will not be enumerated one by one here.

[0041] Further, in some preferred embodiments, the carrying part 200 of the evacuation platform of the present application is movably arranged on the connecting part 100; the evacuation platform is provided with a first power device, and the carrying part 200 can move reciprocatingly along the height direction of the connecting part 100 under the driving of the first power device to approach or move away from the suspended sky train 500. Specifically, the first power device can be arranged at any position of the evacuation platform as long as it can drive the carrying part 200 to move reciprocatingly, and in the present embodiment, the connecting part and the carrying part are preferably arranged in a guide rail sliding block structure, and specifically, the pulley structure of the elevator can also be referred to. When the connecting part and the carrying part adopt the guide rail sliding block, the first power device can be a motor drive, and the specific structure and transmission form will not be described here. Those skilled in the art can also flexibly arrange the connecting structure of the connecting part and the carrying part according to the actual situation on the basis of the principle, and select a suitable first power device for driving, as long as the carrying part needs to reach a safe carrying capacity. The carrying part 200 is arranged below the suspended sky train when the train is running, and does not interfere with the running of the suspended sky train. When an emergency occurs and evacuation is needed, the carrying part 200 can rise to approach the suspended sky train to facilitate passenger evacuation and escape. When the number of passengers reaches the rated load of the carrying part 200, the carrying part 200 is controlled to move downward by the first power device to transport the passengers to a safe area. The design of the lifting structure takes into account the multiple use of the large-span bridge. Since the carrying part 200 of the evacuation platform of the present application can move along the height direction of the connecting part 100, when the connecting part 100 of the present application is connected to a large-span bridge, or in the same vertical direction of multiple traffic routes, the lifting design can move the passengers needing evacuation from the traffic route of the track beam to above the large-span bridge, or to other traffic routes. For example, the Wuhan Yangtze River Bridge, as a public and private dual-purpose large-span bridge, has multiple traffic routes. When the track beam and the suspended sky train are arranged below the Wuhan Yangtze River Bridge, the evacuation platform of the present application can use the lifting method to transport the people needing evacuation to the double-lane four-lane or double-line rail above.

[0042] In some preferred embodiments, the carrying part 200 is hinged to the connecting part 100. Since the carrying part 200 is signal-connected to the first power device, the carrying part 200 can rotate around the hinge part with the connecting part 100 under the driving of the first power device. It can be understood that when the evacuation platform is used to carry passengers, the included angle slope between the carrying part 200 and the connecting part 100 should be less than 10% to ensure the safety of the passengers and the normal use of the evacuation platform. With this slope, the slope plate is ensured to be gentle, and the safety of the passenger flow evacuation is further ensured.

[0043] In some preferred embodiments, the bearing part 200 is a sliding telescopic structure, which comprises a first structure and a second structure, the first structure is installed on the connecting part 100, the second structure is movably connected with the first structure, and the second structure is signal connected with the first power device; the second structure can be slidably moved above the first structure or between the first structure and the suspended sky train 500 under the driving of the first power device. Specifically, two parallel guide rails are arranged on the upper surface of the first structure, and the lower surface of the second structure is provided with sliding blocks matched with the two guide rails, the second structure can slide along the guide rails in the direction of the suspended sky train through the sliding blocks, and correspondingly, the upper surface of the first structure is provided with a limiting device, which can limit the movement of the second structure to avoid the second structure deviating from the predetermined track.

[0044] Based on the above-mentioned inventive concept, in another preferred embodiment of the present application, the bearing part 200 is a telescopic structure, which comprises a first structure and a second structure, the first structure and the second structure are connected through a telescopic connecting piece, one end of the telescopic connecting piece is fixed with the first structure, the other end is fixed with the second structure, and the second structure is signal connected with the first power device; the second structure can move in the direction of the suspended sky train 500 under the driving of the first power device, preferably, the telescopic structure of the present application adopts a telescopic cross-link structure, specifically, a lifting vehicle specially used for Viro light or outer wall of high place, which has good compression resistance and large bearing capacity, is a preferred structure form of the telescopic structure of the present application, and other forms can also be designed by those skilled in the art.

The guide rail has the same length as the track beam, and the evacuation platform can move to a designated position on one side of the track beam through the guide rail and interface with the suspended air train through the bearing part. Since the installation environment of the present embodiment is preferably a large-span bridge, the external structure in the present embodiment is a large-span bridge. Those skilled in the art can also install the evacuation platform of the present application to a tunnel or other locations according to actual conditions.

[0050] Preferably, the evacuation platform is provided with a positioning device, and the evacuation platform can be precisely positioned and interfaced with the suspended air train 500 through the positioning device when the evacuation platform moves along the extension direction of the track beam 500.
