[0040] In order to make the embodiments, technical solutions and advantages of the present invention more obvious, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are part of the embodiments of the present invention, rather than all the embodiments. It should be understood by those skilled in the art that these implementation modes are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0044] In order to more clearly illustrate the suspended air-rail evacuation platform of the present invention, a preferred embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0045] As a preferred embodiment of the present invention, the suspended sky-rail evacuation platform of the present invention includes an evacuation platform 100 and a track 200, wherein the track 200 is arranged on the track beam 400 and extends along the length direction of the track beam 400; the evacuation platform 100 includes a load-bearing platform 110, a robotic arm 130, a moving device 120, and a controller, wherein the moving device 120 is movably installed on the track 200, the lower end of the robotic arm 130 is connected to the moving device 120, and the other end of the robotic arm 130 is connected to the load-bearing platform 110; the load-bearing platform 100, the robotic arm 130 and the moving device 120 are all connected to the controller signal, and the controller is configured as follows: driving the moving device 120 to drive the robotic arm 130 and the load-bearing platform 110 to move to a specified position on the track 200; driving the robotic arm 130 to contract or stretch, so as to drive the load-bearing platform 110 to move downward, and dock with the suspended sky-rail, so as to allow passengers to get on / off the suspended train.

[0046] The track 200 and the track beam 400 of the present invention can be installed in various ways. Figure 1-9 , Figure 1 , Figure 2 , Figure 6 The track 200 shown is disposed on the upper surface of the track beam 400; Figure 3 The track 200 shown is arranged on the track beam 400 through the column, and the plane where the track 200 is located is higher than the upper surface of the track beam 400; Figure 4 , Figure 5 , Figure 7 Figure 8 The track 200 shown is arranged on the side of the track beam 400; the preferred embodiment of the present invention is attached Figure 3The track 200 shown is arranged on the track beam 400 through the column, and the plane where the track 200 is located is higher than the upper surface of the track beam 400 or the track 200 is arranged on the side wall of the track beam 400; by setting up the track in the above manner, the movement range of the suspended air-rail evacuation platform of the present invention is maximized and unrestricted. The track arranged on the upper surface of the track beam makes the movement range of the suspended air-rail evacuation platform of the present invention limited to only between two adjacent columns; by arranging an evacuation ladder on the suspended air-rail evacuation platform of the present invention or on the adjacent columns, the suspended air-rail evacuation platform of the present invention is used as a transfer platform, allowing passengers to evacuate through the evacuation platform of the present invention to the evacuation ladder and finally reach a safe area.

[0047] In some preferred embodiments, the structure of the evacuation platform 100 of the present invention can be referred to Figure 2 , including a supporting platform 110, a mechanical arm 130, and a moving device 120 connected in sequence, wherein the moving device 120 includes a walking mechanism 121 and a driving mechanism, wherein the walking mechanism 121 matches the track 200, and the driving mechanism is connected to the walking mechanism 121 via a communication link, and the walking mechanism 121 can walk along the extension direction of the track 200 under the drive of the driving mechanism, thereby driving the mechanical arm 130 and the supporting platform 110 of the present invention to move synchronously. When the suspended air-rail evacuation platform of the present invention is traveling without load, the mechanical arm 130 is in an initial posture; the initial state refers to Figure 1 When the suspended air-rail evacuation platform of the present invention reaches the target position, the robotic arm 130 extends or contracts from the initial posture, moves with the carrying platform 110, and docks with the suspended air-rail.

[0048] The evacuation platform 100 of the present invention is installed on the track beam 400, and its installation position is various, such as Figure 1 As shown, Figure 1 The schematic diagram of the evacuation platform 100 shown is matched with the track beam when not in operation, wherein the moving device 120 is matched with the track 200 arranged above the track beam, the carrying platform 110 is arranged on one side of the track beam, and the mechanical arm 130 is in a retracted state, so it is not shown in the figure. Through such an arrangement, the evacuation platform of the present invention is convenient to place and save space on the one hand, and has a beautiful structure on the other hand, and will not interfere with the external environment.

[0049] Further, in some preferred embodiments, the evacuation platform 100 of the present invention is installed on one side of the track beam 400. Figure 3-5 , Figure 3 , Figure 4 , Figure 5The moving devices 120 are matched with the track 200 installed on the side of the track beam, and can move along the length direction of the track beam. It should be noted that the height direction of the track relative to the track beam is not limited, as long as it is set on one side of the track beam and along the length direction of the track beam. At this time, the track 200 can be divided into multiple track segments of the same length as the track beam 400. The track segments and the track beam can be integrated into a processing and molding design to save costs and facilitate mass production. At the same time, the stability of the track relative to the track beam can be better guaranteed. Setting the track on the side of the track beam can save materials for the robot arm 130, shorten the cantilever distance, and reduce kinetic energy loss.

[0050] Furthermore, one end of the mechanical arm 130 is connected to the mobile device 120, and the other end is connected to the carrying platform 110, and the mechanical arm 130 is a retractable structure. Figure 7 and Figure 8 . The mechanical arm in the present invention includes a first arm body, a second arm body, and a third arm body connected in sequence; the first arm body is hinged to the moving device 120, a first cavity is provided inside the first arm body, a screw mechanism is installed inside the first cavity, the second arm body is connected to the first arm body through the screw mechanism, the second arm body can extend or retract into the first cavity, one end of the second arm body away from the first arm body is hinged to the third arm body, a second cavity is provided inside the second arm body, the third arm body can rotate relative to the second arm body and retract into the second cavity, and one end of the third arm body away from the second arm body is hinged to the evacuation platform.

[0051] The above-mentioned screw mechanism includes a power device, a screw body and a ball sleeve, wherein the power device is fixedly installed in the first cavity and connected to the screw body, the ball sleeve is sleeved outside the screw body and is threadedly connected to the screw body, and the ball sleeve is fixedly connected to the second arm body. Specifically, the power device uses a drive motor, which is fixedly installed in the first cavity and connected to the screw body to drive the screw body to rotate. The ball sleeve is sleeved outside the screw body and is threadedly connected to the screw body. When the drive motor is started, the ball sleeve rotates relative to the screw body, the position of the screw body remains unchanged, and the ball sleeve is displaced along the axial direction of the screw body. The ball sleeve is fixedly connected to the second arm body to drive the second arm body to displace along the axial direction of the screw body, so that the second arm body extends or retracts into the first cavity. Based on the above principle, the second arm body of the present invention adopts the same setting to drive the extension or retraction of the third arm body. Those skilled in the art may also use other methods to realize the movement form between the first arm body, the second arm body, and the third arm body, which will not be listed one by one here. The movement form of the mechanical arm of the present invention is realized by the above-mentioned first arm body, the second arm body, and the third arm body. In the initial state, the second arm body is retracted into the first cavity of the first arm body, and the third arm body is also retracted into the second cavity. The bearing platform rotates and fits tightly with the third arm body. At this time, the evacuation platform of the present invention minimizes the occupied area, saves energy, and is suitable for small spaces. When the evacuation platform of the present invention arrives at the designated location and needs to rescue passengers, the mechanical arm 130 extends or contracts from the initial posture, drives the bearing platform 110 to move, and docks with the suspended air rail. Specifically, the second arm body extends from the inside of the first cavity, and the third arm body also extends from the inside of the second cavity. The first arm body can also be hinged with the mobile device to change the movement form of the mechanical arm 130 of the present invention. The carrying platform 110 of the present invention is hinged to the mechanical arm 130. When arriving at a designated location and requiring rescue, the carrying platform rotates around the hinged portion with the third arm body to dock with the escape door of the suspended skytrain.

[0052] Furthermore, the present invention has one or more robotic arms, and the drawings of the present invention illustrate two robotic arms, and the two robotic arms move synchronously under the drive of the controller to make the carrying platform more stable.

[0053] In some preferred embodiments, the mechanical arm 130 of the present invention is movably connected to the mobile device 120, see Figure 5The walking mechanism of the mobile device of the present invention can be a U-shaped structure. The U-shaped structure is fixed to the track beam to be more firm and reliable. Then, a track is provided on the mobile device 120, and a rotating structure matching the track on the mobile device 120 is provided on the mechanical arm 130. The mechanical arm 130 walks (rotates) along the track on the mobile device 120 through the rotating structure.

Figure 5 The mobile device of the present invention is U-shaped, and the track on the mobile device is also U-shaped, and its coverage includes the upper surface, right side surface, and lower bottom surface (one side) of the track beam 400. The robot arm 130 can walk along the track, that is, the robot arm can be fixed on the upper surface or side surface of the track beam at one end. For details, please refer to Figure 6 and Figure 7 The walking path of the evacuation platform robotic arm is shown.

[0054] Preferably, the carrying platform 110 includes a carrying portion and a connecting portion, the carrying portion is mounted on the robot arm 130 through the connecting portion, the carrying portion is hinged to the connecting portion, and the carrying portion can rotate around the hinge between the carrying portion and the connecting portion.

[0055] Furthermore, in some preferred embodiments, the present invention further comprises a telescopic member power device, the telescopic member power device is connected to the bearing part through a communication link, specifically, the bearing part comprises a first structure and a second structure, the first structure is mounted on the connecting part, and the second structure is movably connected to the first structure; in the first embodiment of the present invention, the movably connected is a telescopic connection, specifically, the first structure and the second structure are connected through a telescopic connecting member, one end of the telescopic connecting member is fixed to the first structure, and the other end is fixed to the second structure; the telescopic connecting member is signal-connected to the telescopic member power device, and the second structure can move above the first structure or between the first structure and the suspended skytrain under the drive of the telescopic connecting member, so as to expand the bearing area of ​​the evacuation platform to carry more passengers. Preferably, the telescopic connecting member is composed of a telescopic cross-link structure. The telescopic cross-link structure adopted in this embodiment makes it highly stable after being extended, and its wide working platform and high bearing capacity are the best choice for aerial work.
