The movable platform track evacuation platform uses the operation of the motor to drive the first rotating rod to rotate, and the rotation of the first rotating rod drives the first pulley to rotate, and then drives the third pulley to rotate, and then drives the second rotating rod to rotate, thereby driving the first drive wheel and the second pulley to rotate, and the rotation of the second pulley drives the fourth pulley to rotate, and then drives the third rotating rod to rotate, and finally drives the second drive wheel to rotate. The above technical solution realizes the movement of the evacuation platform, improves the efficiency of evacuation, reduces the possibility of stampede accidents during the evacuation process, and facilitates the evacuation of pregnant women, injured people, disabled people and other people who are inconvenient to walk. The above technology is conducive to practical application.

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention.

[0021] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or includes elements inherent to such process, method, article, or apparatus. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0024] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances. Example

[0025] like Figure 1-2 As shown in the figure, the present invention proposes a movable evacuation platform comprising an open-top carriage 1 and track troughs 10. Seats 2 are fixedly mounted on both sides of the inner wall of the carriage 1, and cushioning panels are mounted on the seats 2. The cushioning panels are made of soft polyurethane and provide a comfortable seating environment. An entrance and exit are provided on the side of the carriage 1 facing away from the storage tank 3. Door panels 4 are hingedly connected to the entrance and exit, allowing passengers to enter and exit the carriage 1.

[0026] The bottom of the carriage 1 is fixedly mounted with rollers 5, which are in rolling contact with the inner wall of the track groove 10. Two shovels 6 are fixedly mounted on the lower side of the carriage 1, located in the direction of the rollers 5's rotation. The shovels 6 are tilted to facilitate scooping up debris. The bottom of the shovels 6 is in sliding contact with the bottom inner wall of the track groove 10. Deflectors 20 are fixed on both sides of the end of the shovels 6 away from the carriage 1 to prevent debris from falling out and facilitate its accumulation.

[0027] In this embodiment, the storage box 3 is detachably mounted between two shovel plates 6. Bolts are threadedly mounted on both sides of the storage box 3, and threaded holes are provided on the shovel plates 6 to accommodate the bolts. This allows for easy removal of the storage box 3, allowing for easy cleaning of debris and subsequent use. The storage box 3 is open at both ends, and a push plate 7 is slidably connected to the side of the shovel plates 6 facing away from the storage box 3. The open shape of the push plate 7 is compatible with the push plate 7, facilitating the insertion of debris.

[0028] It's worth noting that a horizontal baffle 8 is fixedly mounted on the outer side of the lower end of the push plate 7. The baffle 8's length is greater than the distance between the two deflectors 20. This prevents debris from being carried away during the reciprocating motion of the push plate 7. The push plate 7 is in sliding contact with the top of one of the deflectors 20. Two push rods 19 are fixedly mounted on the outer side of the push plate 7. A push mechanism that drives the push rods 19 is fixed to the side of the shovel plate 6 facing away from the storage tank 3. This mechanism drives the push plate's reciprocating motion, pushing debris into the storage tank 3.

[0029] like Figure 3-5As shown, the pushing device includes a drive box 9, which is fixed to the shovel plate 6. A motor 11 is fixedly installed inside the drive box 9. The output shaft of the motor 11 is fixedly sleeved with a pulley 12. A rotating shaft 16 is rotatably installed inside the drive box 9. A cam 15 and a pulley 14 are fixedly sleeved on the rotating shaft 16. A belt 13 is provided between the pulleys 12 and 14. A sliding plate 17 is slidably installed inside the drive box 9. The sliding plate 17 rests on the curved surface of the cam 15. The end of the push rod 19 away from the push plate 7 slides through one side of the drive box 9 and is fixedly connected to the sliding plate 17. A sliding hole is opened on the side of the drive box 9 close to the push plate 7. The push rod 19 is slidably connected to the inner wall of the sliding hole. The sliding hole is provided for installing the push rod 19. A spring 18 is provided between the inner wall of one side of the drive box 9 and the sliding plate 17, which is slidably sleeved on the push rod 19. The elastic force of the spring 18 causes the sliding plate 17 to be constantly pressed against the curved surface of the cam 15, thereby realizing the reciprocating motion of the push plate 7 and pushing the debris accumulated on the shovel plate 6 into the storage box 3, thereby realizing the collection of the debris particles.

[0030] The working principle of this embodiment is as follows: when the carriage 1 moves forward, the shovel plate 6 in the rolling direction of the roller 5 will scoop up the debris and start to accumulate it, and at the same time, the motor 11 is started, and the motor 11 drives the rotating shaft 16 and the cam 15 to rotate through the belt 13, so that the sliding plate 17 resting on the curved surface of the cam 15 drives the push rod 19 and the push plate 7 to be pushed outward, and the elastic force of the spring 18 makes the sliding plate 17 always squeezed on the curved surface of the cam 15, realizing the reciprocating motion of the push plate 7, and continuously pushing the accumulated debris into the storage box 3 from the openings at both ends, so as to clear the debris in the track groove 10 before the roller 5 arrives, greatly reducing the possibility of the roller 5 being bumped or out of the track groove 10 due to debris, improving the safety and functionality of the device, and eliminating the need for additional manual cleaning, saving labor and improving convenience of use.

[0031] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
