Description

Technical Field

[0001] The invention belongs to the technical field of high-speed maglev traffic evacuation, and in particular relates to an emergency evacuation platform suitable for high-speed maglev trains. Background Art

[0002] With the continuous development of rail transit technology and the 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 begun to heat up year by year, and Changdao high-speed maglev has initially achieved commercial application or reached the level of commercial application.

[0003] Existing conventional high-speed maglev vehicles generally adopt the setting form of holding the track, using the long stator linear motor segmented power supply technology for traction and drive, and the design of redundant important subsystems and components makes high-speed maglev vehicles safer and more reliable than wheel-rail trains. However, the high-speed maglev system has many electrified equipment and a complex operating environment, and it is necessary to fully consider the evacuation method of passengers in the event of a sudden failure in the auxiliary parking area or tunnel.

[0004] At present, for the evacuation in the viaduct section of high-speed maglev transportation, the common practice is to set up an auxiliary parking area with passenger evacuation conditions, and set up an evacuation passage in the auxiliary parking area, so that when a train fails on the viaduct, it can slide to the auxiliary parking area for parking, and then escape through the evacuation passage; for evacuation in the tunnel section, the existing practice is to set up an evacuation platform so that passengers can go down to the evacuation platform through the door. However, the speed level of high-speed maglev is generally 400-600km / h, and its aerodynamic effect and track beam are very different from traditional wheel-rail, resulting in the distance between the evacuation platform and the train door being farther than that of traditional rail transportation. For example, in the tunnel section, the height difference between the floor surface of a 600km / h maglev vehicle and the evacuation platform is 900mm, and the minimum distance between the evacuation platform and the side of the vehicle is 690mm. Such a large height difference and level difference makes the evacuation from the train to the evacuation platform pose a certain safety hazard. In addition, the escape and evacuation are often carried out in a tense atmosphere or dimly lit conditions, which makes it very easy for people to fall during the evacuation process, endangering the safety of passengers.

[0049] Example:

[0050] See also Figures 1 to 11 The emergency evacuation platform in the preferred embodiment of the present invention is arranged on one side of the high-speed maglev train running track, and is further preferably arranged in the auxiliary parking area or tunnel section of the high-speed maglev transportation. Since the running speed of the high-speed maglev train is greatly improved compared with ordinary railway transportation and medium and low-speed maglev, it is necessary to reserve a large safety space on both sides of the vehicle when designing high-speed maglev transportation. This makes the design of structures such as evacuation platforms significantly different from traditional rail transportation, which leads to a certain height difference and horizontal distance between the evacuation platform and the train door in high-speed maglev transportation. In view of this, on the emergency evacuation platform in the preferred embodiment, the following is arranged Figure 1 , 2 The telescopic evacuation bracket 1 shown in the figure is used to form a continuous walking passage between the evacuation platform 2 and the car body 3. When the walking passage is formed, it extends obliquely downward from one side of the car body 3 to the top surface of the evacuation platform 2, and then the passengers on the train can be quickly evacuated from the door 4 to the evacuation platform 2 via the telescopic evacuation bracket 1.

[0051] Specifically, the telescopic evacuation support 1 in the preferred embodiment includes a pair of hinged components, the two hinged components are arranged opposite to each other, and a plurality of pedals 105 are arranged between the two, so that after the telescopic evacuation support 1 is unfolded, the plurality of pedals 105 can form a continuous step structure, such as Figure 1 as shown in .

[0052] Furthermore, each hinge assembly in the preferred embodiment includes a plurality of first hinge pairs 101 and second hinge pairs 102 respectively arranged at both ends of the hinge assembly, and a first support rod 103 is respectively arranged corresponding to the support of each hinge assembly, and a plurality of second support rods 104 are arranged corresponding to the simultaneous support of the two hinge assemblies.

[0053] like Figure 1 As shown in , the first hinge pairs 101 in the hinge assembly are multiple hingedly arranged in sequence. The more the number of first hinge pairs 101 is arranged, the longer the extension length of the telescopic evacuation bracket 1 after being unfolded. In a preferred embodiment, the number of first hinge pairs 101 is 1 to 8, for example Figure 1 5 shown in .

[0054] Specifically, the first hinge pair 101 includes two hinge rods of equal length, and the middle parts of the two hinge rods are hinged to each other, so that the angle between the two hinge rods can be adjusted accordingly. At the same time, the two adjacent first hinge pairs 101 are rotatably connected by end hinges to form a continuous hinge unit. Correspondingly, a second hinge pair 102 is respectively provided at both ends of the hinge unit, which includes two hinge rods of equal length, one end of the two hinge rods is hinged to each other, and the other end is hinged to the end of the hinge unit. In addition, the length of the hinge rod in the second hinge pair 102 is preferably equal to half the length of the hinge rod in the first hinge pair 101, so as to ensure that the distance between each pedal is equal.

[0055] However, it is obvious that the length of each hinge rod and the number of each hinge pair can be preferably set according to the design length of the telescopic evacuation bracket 1. In actual setting, the length of each hinge rod is preferably corresponding to the width of the pedal 105, so that when the telescopic evacuation bracket 1 is unfolded, the two ends of the pedal 105 in the width direction are respectively flush with the ends of the hinge rods of the hinge pair where the pedal 105 is located in the vertical direction.

[0056] Furthermore, the pedal 105 in the preferred embodiment is arranged between two hinged assemblies, and the two ends of the pedal 105 are respectively hinged between two hinged pairs arranged horizontally opposite to each other, and the hinged positions at the two ends of the pedal 105 are respectively the hinged positions of the two hinge rods in the hinged pair, that is, the middle of the first hinged pair 101 and the end of the second hinged pair 102. In actual setting, two second hinged pairs 102 are arranged, but one of the second hinged pairs 102 needs to be connected to the evacuation platform 2, so the second hinged pair 102 provided with the pedal 105 is actually only one on the side close to the train track area. It is not difficult to see that in actual setting, the second hinged pair 102 provided with the pedal 105 can also be replaced by the first hinged pair 101, except that the ends of the replaced first hinged pair 101 are freely arranged.

[0057] like Figure 1 , 2As shown in the figure, first support rods 103 are respectively provided corresponding to the unfolding and folding of each hinge assembly, and the two first support rods 103 are respectively arranged below the corresponding hinge assembly, and are preferably arranged opposite to each other in the horizontal direction, and are further specifically retractable and rotatable support rods, respectively including a coaxially arranged first rotating rod 1031 and a first telescopic rod 1032.

[0058] Among them, one end of the first rotating rod 1031 is rotatably connected to the side wall surface of the evacuation platform 2 facing the train running area, and the first telescopic rod 1032 is coaxially matched to the outer periphery of the other end of the first rotating rod 1031, and can be reciprocated and telescoped axially relative to the side end. Correspondingly, the other end of the first telescopic rod 1032 is hinged to the hinge of the two hinge rods in the corresponding first hinge pair 101. Through the combination of the telescopic movement of the first telescopic rod 1032 and the rotational movement of the first rotating rod 1031, the expansion of the single-sided hinge assembly or the retraction and folding of the unfolded hinge assembly can be achieved. Obviously, in actual work, the two first support rods 103 move synchronously to ensure that the two hinge assemblies are retracted and expanded in unison. In actual settings, the first support rod 103 can be further preferably a hydraulic drive rod.

[0059] Furthermore, a second support rod 104 is also provided for driving and supporting the telescopic evacuation bracket 1, and its configuration is preferably similar to the structural configuration of the first support rod 103, namely, it includes a second rotating rod 1041 and a second telescopic rod 1042 that are correspondingly matched. One end of the second rotating rod 1041 is rotatably connected to the side wall surface of the evacuation platform 2 facing the train running area, and the second telescopic rod 1042 is coaxially matched to the outer periphery of the other end of the second rotating rod 1041, and can be reciprocated and telescoped relative to the side end along the axial direction.

[0060] However, the arrangement of the second support rod 1041 is different from that of the first support rod 103 in that the end of the second rotation rod 1041 is connected to the side wall of the evacuation platform 2 between the two hinged assemblies, and the distance between the second support rod 104 and the two first support rods 103 is preferably equal to ensure the balance and stability of the supporting force. At the same time, a rotation support rod 1043 and a rotation cross bar 1044 are also provided corresponding to the second telescopic rod 1042. The rotation support rods 1043 are arranged in pairs, one end of each rotation support rod 1043 is hinged to the corresponding hinge pair, and the other end is fixedly connected to the end of the rotation cross bar 1044; preferably, the end of the rotation support rod 1043 is connected to the hinge pair on the side of the first telescopic rod 1032 close to the train track area, for example Figure 1 Accordingly, the rotating crossbar 1044 is horizontally arranged, and its axis is parallel to the axial direction of the pedal 105, as shown in FIG. Figure 3The rotating cross bar 1044 passes through the end of the second telescopic rod 1042 and rotates to match it, and then the load on the telescopic evacuation bracket 1 can be transferred to the rotating cross bar 1044 through the two rotating support rods 1043, and then transferred to the second telescopic rod 1042 and the second rotating rod 1041 through the rotating cross bar 1044.

[0061] With the rotation and extension of the two first support rods 103, the second support rod 104 can be rotated and extended accordingly, and provide auxiliary support for the telescopic evacuation bracket, such as Figure 1 When the two first support rods 103 are in a retracted state, the second support rod 104 is also in a retracted state and is stored at the bottom of the telescopic evacuation bracket 1, as shown in FIG. Figure 2 , 3 as shown in .

[0062] In actual setting, corresponding to the connection of the relevant components on the telescopic evacuation bracket 1 on the evacuation platform 2, a plurality of supports 106 are preferably provided. Each support 106 is respectively provided on the wall surface of the evacuation platform 2 facing the track area, and can correspondingly realize the articulation of the second hinge pair 102 at the end of the hinge assembly, the first rotation rod 1031 of the first support rod 103, and the second rotation rod 1041 of the second support rod 104 on the wall surface of the evacuation platform 2. That is, in a preferred embodiment, the number of supports 106 provided is 5, which are arranged at intervals, such as Figure 3 Accordingly, in actual configuration, the support 106 for connecting the end of the second support rod 104 is located between the support 106 for connecting the end of the hinge assembly and the support 106 for connecting the end of the first support rod 103, so that the two support rods can provide support for the telescopic evacuation bracket 1 at different support angles, such as Figure 1 as shown in .

[0063] In addition, considering that the parking position of the high-speed maglev train on one side of the evacuation platform 2 is deterministic, in order to ensure that the high-speed maglev train can meet the evacuation requirements when it stops on one side of the evacuation platform 2, in actual setting, the telescopic evacuation brackets 1 on the side wall of the evacuation platform 2 are multiple and continuously arranged in the extension direction of the evacuation platform 2, so that when the high-speed maglev train stops at any position on one side of the evacuation platform 2, there will be a telescopic evacuation bracket 1 corresponding to the train door 4. Further preferably, the spacing between two adjacent telescopic evacuation brackets 1 is not greater than half the length of the pedal 105.

[0064] In summary, for the telescopic evacuation support 1 in the preferred embodiment, its state when not working is as follows Figure 2 , 3 As shown in , at this time, the first support rod 103 and the second support rod 104 are both in a retracted state, and the two hinge components are folded respectively, and the multiple pedals 105 are approximately in a state of being stacked in sequence in a horizontal direction.

[0065] When the high-speed maglev train stops at one side of the evacuation platform 2, and the telescopic evacuation bracket 1 and the corresponding door 4 on the car body 3 are in / approximately in the same vertical plane, the corresponding relationship between the evacuation platform 2 and the car body 3 is as follows: Figures 8 to 11 As shown in . After that, the first rotating rod 1031 of the two first supporting rods 103 is controlled to rotate upward synchronously, and the two first telescopic rods 1032 are synchronously extended outward, so that the two hinged components are converted from the folded state to the unfolded state, and each pedal 105 is converted from the vertical state to the horizontal state. While the first supporting rod 103 rotates and extends, the second supporting rod 104 rotates and extends synchronously accordingly. After the telescopic evacuation bracket 1 is fully deployed, each supporting rod is locked separately, and the corresponding relationship between the evacuation platform 2 and the vehicle body 3 is as shown in FIG. Figures 4 to 7 At this time, a continuous walking staircase is formed between the door 4 and the evacuation platform 2, and the passengers on the high-speed maglev vehicle can be evacuated through the telescopic evacuation bracket 1.

[0066] After the telescopic evacuation bracket 1 completes the evacuation work, the support rods are synchronously controlled to rotate and retract, and the hinge pairs are retracted to a folded state, so that the end of the telescopic evacuation bracket 1 is away from the operating limit of the high-speed maglev train.

[0067] The emergency evacuation platform suitable for high-speed maglev trains in the present invention has a simple structure and is easy to set up. It can quickly and accurately form a continuous evacuation ladder between the ground at the door of the high-speed maglev train and the ground of the evacuation platform, thereby providing a guarantee for the emergency evacuation of the high-speed maglev train in an emergency situation, avoiding the falling of people from the train during the emergency evacuation, ensuring the personal safety and property safety of passengers, and further promoting the application of high-speed maglev rail transportation technology. It has good application prospects and promotion value.

[0068] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
