Description

Technical Field

[0001] The present invention belongs to the technical field of high-speed maglev transportation evacuation, and particularly relates to an evacuation step system for high-speed maglev vehicles. Background Art

[0002] With the continuous development of rail transit technology and the increasing improvement of people's living standards, the requirements for travel quality and travel efficiency are also constantly increasing. At present, although the operating speed of traditional wheel-rail rail transit has been greatly improved compared with before, the operating speed is limited by the wheel-rail adhesion limit and it is difficult to increase it significantly. At the same time, with the continuous accumulation and development of maglev rail transit technology, the research enthusiasm for high-speed maglev rail transit has been increasing year by year, and the conventional high-speed maglev has initially achieved commercial application or reached the level of commercial application.

[0003] Existing conventional high-speed maglev vehicles generally adopt a running form of hugging the rail, use the long stator linear motor sectional power supply technology for traction drive, and coupled with the design of redundant settings of important subsystems and components, making the high-speed maglev vehicle safer and more reliable than the wheel-rail train. However, the high-speed maglev system has many electrification devices and a complex operating environment, and it is necessary to fully consider the evacuation and escape methods of passengers when the train suddenly fails in the auxiliary parking area or in the tunnel.

[0004] Currently, for the evacuation in the viaduct section of high-speed maglev transportation, a common practice is to set up an auxiliary parking area with conditions for passenger evacuation and escape, and correspondingly set up an evacuation passage in the auxiliary parking area, so that when the train breaks down on the viaduct, it can slide to the auxiliary parking area for parking, and then escape through the evacuation passage; for the evacuation and escape in the tunnel section, the existing practice is to set up an evacuation platform so that passengers can get off the train door and down to the evacuation platform. However, the speed level of high-speed maglev is generally 400 - 600 km / h, and its aerodynamic effect and track beam are very different from those of traditional wheel-rail, resulting in a greater distance between the evacuation platform and the train door compared with traditional rail transit. For example, in the tunnel section, the height difference between the floor surface of a 600 km / h maglev vehicle and the evacuation platform is 900 mm, and the minimum distance between the evacuation platform and the side of the vehicle is 690 mm. Such a large height difference and horizontal difference make the evacuation from the train to the evacuation platform have certain safety hazards. Coupled with the fact that the evacuation and escape are often under a tense atmosphere or dim light conditions, it is extremely easy for people to fall during the evacuation process, endangering the safety of passengers.

[0047] Embodiment:

[0048] Please refer to Figures 1 to 6 , in the evacuation step system of the high-speed maglev vehicle in the preferred embodiment of the present invention, it is arranged in the vehicle body 8 below the door 7 of the high-speed maglev train. It includes an evacuation chamber 6 opened at the bottom of the door 7, a fixed pedal 1 and a flipping pedal 2 arranged in the evacuation chamber 6, and a telescopic support plate 3 arranged in the vehicle body 8 below the evacuation chamber 6. Correspondingly, a cover plate 5 is arranged at the position where the evacuation chamber 6 communicates with the vehicle interior floor, and a retractable skirt plate 4 is arranged on the wall surface of the vehicle body 8 below the opening position of the door 7. By opening the cover plate 5 and the skirt plate 4 simultaneously, the vehicle interior space can communicate with the outside of the train through the evacuation chamber 6. Through the matching work of the fixed pedal 1 and the flipping pedal 2, a step system connecting the inside and outside of the vehicle can be formed, enabling communication between the inside of the high-speed maglev train and the evacuation platform / evacuation passage, and completing the rapid evacuation of the personnel on the train.

[0049] Specifically, the evacuation step system in the preferred embodiment includes a fixed pedal 1, which is a stepped structure continuously extending downward from the vehicle interior floor, including a plurality of vertical plates and a plurality of horizontal plates connected in sequence, and each vertical plate and each horizontal plate are respectively fixed in the evacuation chamber 6. At the same time, one end of the fixed pedal 1 is connected to the vehicle interior floor with the top surface of the vertical plate, and the other end extends to the outer side wall surface of the vehicle body 8 with the edge of the horizontal plate.

[0050] For example, in one embodiment, the fixed pedal 1 is as Figure 1 shown in, which includes a first fixed vertical plate 101, a first fixed horizontal plate 102, a second fixed vertical plate 103 and a second fixed horizontal plate 104 connected in sequence. The top of the first fixed vertical plate 101 is connected to the vehicle interior floor, and the edge of the second fixed horizontal plate 104 extends to a position close to the outer side wall surface of the vehicle body. Through the above arrangement, two steps of fixed pedals can be formed on the ground at the opening position of the train door 7.

[0051] Furthermore, a flipping pedal 2 is hinged at one end of the fixed pedal 1 away from the vehicle interior bottom surface, so that the flipping pedal 2 can be retracted into the evacuation chamber 6 when not in use and flipped out of the vehicle body 8 when in use.

[0052] Continuing with the structure shown in Figure 1 as an example for introduction, at this time, the flipping pedal 2 includes a first flipping cross plate 201, a first flipping vertical plate 202, and a second flipping cross plate 203 that are sequentially connected in a stepped shape. Among them, the first flipping cross plate 201 is hinged to the edge of the second fixed cross plate 104 on the side facing away from the first flipping vertical plate 202, so that the first flipping cross plate 201 can rotate relative to the edge of the second fixed cross plate 104, enabling the first flipping cross plate 201 to rotate (rotate 180°) from the position where it fits against the second fixed cross plate 104 to the position flush with the second fixed cross plate 104. At this time, the fixed pedal 1 and the flipping pedal 2 are butted to form a continuous evacuation pedal system, as shown in Figure 1 shown in

[0053] In actual setting, the edges of the fixed pedal 1 and the flipping pedal 2 are hinged by a number of hinge members, and the flipping pedal 2 in the preferred embodiment includes a first flipping cross plate 201, a first flipping vertical plate 202, and a second flipping cross plate 203 arranged in sequence. At the same time, the lengths of the above-mentioned flipping plates are preferably the same as the lengths of the respective fixed plates in the fixed pedal 1, and the width dimensions are preferably corresponding to the widths of the corresponding fixed plates, that is, the width of the first flipping cross plate 201 is not greater than the width of the second fixed cross plate 104, the width of the first flipping vertical plate 202 is not less than the width of the second fixed vertical plate 103, and the width of the second flipping cross plate 203 is not greater than the width of the first fixed cross plate 102. In this way, after the flipping pedal 2 is flipped into the evacuation bin 6, the two pedals can be in a parallel state, as shown in Figure 4 shown in. Of course, after the flipping pedal 2 is flipped into the evacuation bin 6, each flipping plate can also be arranged at a certain inclination angle with respect to the corresponding fixed plate, as long as the top of the flipping pedal 2 does not protrude above the vehicle floor.

[0054] Furthermore, a telescopic support plate 3 is also provided corresponding to the flipping pedal 2, and it is preferably horizontally arranged in the vehicle body 8 below the evacuation bin 6, as shown in Figure 4 , 6 shown in. Correspondingly, a telescopic mechanism 301 is provided on the side of the telescopic support plate 3 facing away from the outer peripheral wall surface of the vehicle body 8. A number of telescopic shafts 302 are provided on the telescopic mechanism 301, and the ends of the telescopic shafts 302 are matingly connected to the ends of the telescopic support plate 3. Through the control of the telescopic mechanism 301, the horizontal telescoping of the telescopic support plate 3 can be achieved. In addition, in the preferred embodiment, a horizontally extending telescopic hole 303 is provided in the vehicle body 8 corresponding to the telescoping of the telescopic shaft 302 to realize the guiding and limiting of the telescoping of the telescopic shaft 302. At the same time, the horizontal telescoping distance of the telescopic support plate 3 corresponds to the width of the first flipping cross plate 201, so that when the first flipping cross plate 201 just rotates to the horizontal position, the end of the telescopic support plate 3 just abuts against the end face of the first flipping vertical plate 202 facing the vehicle body 8, as shown in Figure 6As shown in the figure, this is to prevent further flipping of the flipping pedal 2 and achieve position limiting.

[0055] In a preferred embodiment, a position limiting protrusion (not shown in the figure) is provided on the end face of the first flipping vertical plate 202 that matches the telescopic support plate 3. It is preferably provided on the side close to the first flipping horizontal plate 201. When the telescopic support plate 3 abuts against the first flipping vertical plate 202, the position limiting protrusion is just above the end of the telescopic support plate 3 or abuts against the top surface of the end of the telescopic support plate 3, so as to stably support the first flipping vertical plate 202 on the telescopic support plate 3 and further improve the stability of the pedal system setting. Of course, in actual setting, the above support structure can also be set in other forms other than the telescopic support plate 3, such as a number of telescopic rods that can expand and contract independently.

[0056] Further preferably, a second flipping vertical plate (not shown in the figure) can also be preferably provided at the end of the second flipping horizontal plate 203. The set width of the second flipping vertical plate is not greater than the width of the first fixed vertical plate 101. At the same time, by using the setting of the above second flipping vertical plate, when the flipping pedal 2 is rotated out from the evacuation bin 6, the bottom of the second flipping vertical plate can support on the ground of the evacuation platform, thereby further improving the stability of the evacuation pedal system setting. In addition, in the preferred embodiment, a flipping mechanism is provided corresponding to the flipping pedal 2. It is preferably arranged in the vehicle body 8 on one side or both sides of the evacuation bin 6. The flipping structure can be a corresponding servo motor, and by its corresponding operation, the automatic flipping of the flipping pedal 2 can be realized.

[0057] Further, a cover plate 5 and a skirt plate 4 are also provided corresponding to the evacuation bin 6. When the skirt plate 4 and the cover plate 5 are closed at the same time, they preferably abut against each other with side walls, that is, the top side wall of the skirt plate 4 abuts against the side wall of the cover plate 5 facing the vehicle door 7. In this way, it can be ensured that after the cover plate 5, the skirt plate 4, and the vehicle door 7 are completely opened, the side of the evacuation bin 6 close to the vehicle door 7 can communicate with the running space at the vehicle door 7.

[0058] Specifically, the cover plate 5 is arranged to be openable and closable on the ground inside the vehicle, and is used to close the top of the evacuation bin 6 and form a floor for running on one side of the vehicle door 7. In a preferred embodiment, the cover plate 5 is of a split type, as Figure 1 shown in the figure. It includes a first cover plate 501 and a second cover plate 502 that are oppositely arranged. The two cover plates are respectively hinged at the junction of the evacuation bin 6 and the ground inside the vehicle by their sides. By opening the two cover plates from the horizontal state to the vertical state, the evacuation bin 6 can be communicated with the interior of the carriage, and a baffle structure is formed on both sides of the evacuation bin 6 to provide a certain degree of protection for the evacuation of passengers.

[0059] Meanwhile, the skirt board 4 in the preferred embodiment is also preferably arranged in a split type, which includes a first skirt board 401 and a second skirt board 402 that are relatively hinged. The two skirt boards are respectively connected to the outer peripheral wall surface of the vehicle body 8 in a hinged form. By closing the two skirt boards, the flatness of the outer peripheral wall surface of the vehicle body 8 can be restored, and by opening the two skirt boards, the opening of the evacuation compartment 6 close to the outside of the vehicle can be realized, so that the flip pedal 2 can be flipped out from the evacuation compartment 6.

[0060] Of course, in addition to the above form, the cover plate 5 and the skirt board 4 in the preferred embodiment can also be set in other forms according to needs, as long as the top and side parts of the evacuation compartment 6 can be closed and opened. For example, in another preferred embodiment, the skirt board 4 and / or the cover plate 5 are set as an integral plate-like structure and are opened or closed by means of horizontal movement. In addition, a combined driving mechanism is preferably arranged corresponding to the skirt board 4 and the cover plate 5 in the preferred embodiment, and it is preferably arranged in the vehicle body 8 on both sides of the evacuation compartment 6. By using the drive of the combined driving mechanism, the synchronous opening or closing of the skirt board 4 and the cover plate 5 can be realized, which simplifies the control process of the two and improves the opening and closing efficiency of the evacuation compartment 6. Of course, one or two of the driving mechanism of the flip pedal 2 and the telescopic mechanism 301 of the telescopic support plate 3 can also be further coupled with the above combined driving mechanism to realize the synchronous drive of three components or four components, further improving the operation control efficiency and convenience of the evacuation step system.

[0061] In summary, for the evacuation step system of the high-speed maglev vehicle in the preferred embodiment, its state when not working is as Figures 2 to 4 shown in the figure. At this time, the skirt board 4 and the cover plate 5 are closed, the flip pedal 2 is accommodated in the evacuation compartment 6, and the telescopic support plate 3 is in a contracted state. When the vehicle stops normally at the platform, the door 7 is opened, and the cover plate 5 forms a floor structure for passengers to get on and off the vehicle.

[0062] When the high-speed maglev vehicle needs emergency evacuation and stops stably on one side of the evacuation platform, first open the cover plate 5 and the skirt board 4 under the door 7 of the train to open the top and side parts of the evacuation compartment 6, then control the telescopic support plate 3 to extend out a certain distance and lock it. After that, control the flip pedal 2 to perform a flipping movement and rotate out of the evacuation compartment 6 to the outside of the vehicle body 8, so that the flip pedal 2 and the fixed pedal 1 form a continuous stepped pedal structure, and the end of the telescopic support plate 3 just abuts and supports on the flip pedal 2. By using the continuous setting of the fixed pedal 1 and the flip pedal 2, the horizontal distance and vertical distance between the vehicle floor and the evacuation platform / evacuation passage can be effectively compensated, so that the passengers on the vehicle can be quickly and accurately evacuated to the evacuation platform.

[0063] After the evacuation step system completes the evacuation work, first control the flipping pedal 2 to rotate back into the evacuation bin 6, then retract the telescopic support plate 3, close the skirt plate 4 and the cover plate 5 respectively, so that the evacuation bin 6 returns to the closed state, realizing the restoration of the evacuation step system.

[0064] The evacuation step system of the high-speed maglev vehicle in the present invention has a simple structure, is easy to set up and operate, can quickly and accurately form a continuous evacuation step ladder between the ground at the door of the high-speed maglev train and the ground of the evacuation platform, provides guarantee for the emergency evacuation of the high-speed maglev train in case of emergency, avoids the falling of personnel from the train during the emergency evacuation, ensures the personal safety and property safety of passengers, further promotes the development of the high-speed maglev rail transit technology, and has good application prospects and popularization value.

[0065] It is easy for those skilled in the art to understand that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
