[0014] Compared with the prior art, the automatic tube channel of a railway vehicle of the present invention is composed of two sets of split channel structures, which are respectively installed on two carriages, and each set includes a bellows, a frame, a driving mechanism and a control system.

DETAILED DESCRIPTION

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0030] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0031] like Figures 1 to 9 As shown, an automatic gangway for railway vehicles comprises two sets of gangway split structures 1, wherein the gangway split structure 1 comprises a bellows 2, a frame 22, a driving mechanism 25 and a control system 31, wherein the bellows 2 is mounted on the frame 22, the driving mechanism 25 comprises a locking tongue 28, a lock driving motor 29, a telescopic mechanism and a chassis 30, the chassis 30 is mounted in the frame 22, the locking tongue 28, the lock driving motor 29 and the telescopic mechanism are mounted on the chassis 30, the locking tongue 28 is connected to the lock driving motor 29, and is driven by the lock driving motor 29, and the telescopic mechanism and the lock driving motor 29 are electrically connected to the control system 31.

[0032] The automatic tube passage of a railway vehicle of the present embodiment is composed of two sets of through-passage split structures 1, which are respectively installed on two carriages, and each set includes a bellows 2, a frame 22, a driving mechanism 25 and a control system 31. The bellows 2 is installed on the frame 22, providing a passage space for passengers and having functions such as windproof, dustproof, soundproof and heat-insulating. The driving mechanism 25 is composed of a lock tongue 28, a lock driving motor 29, a telescopic mechanism and a chassis 30. The chassis 30 is installed in the frame 22. The lock tongue 28 is connected to the lock driving motor 29 and driven by it. The telescopic mechanism and the lock driving motor 29 are both electrically connected to the control system 31, receive instructions from the control system 31, and complete various operations.

[0033] In actual operation, when the train needs to be coupled, the staff only needs to operate the one-key coupling function of the control system 31 on the display panel, and the docking frame 4 in the bellows 2 will be automatically unlocked, and the telescopic mechanism of the drive mechanism 25 will then guide the bellows 2 to extend forward. When the front and rear end through-passage split structures of the two carriages contact each other, the two through-passage split structures can be accurately closed and docked, and the sensor will trigger a signal to confirm that the docking is completed. Then, the locking mechanism in the bellows 2 is automatically locked, and the telescopic mechanism is automatically retracted, thereby realizing the safe passage of internal personnel. The whole process is fast and efficient, greatly improving the efficiency and convenience of train coupling. In the above settings, the locking mechanism in the bellows 2 is an electric locking mechanism to realize the locked connection of the two bellows. The corresponding lock structure is disclosed in the prior art and will not be repeated here.

[0034] When the gangway needs to be unhooked, the one-key unhooking function of the control system 31 is also operated through the display panel. The docking frame 4 in the bellows 2 in the connected state is automatically unlocked, the telescopic mechanism is pushed out and connected to the bellows 2, and the bellows 2 is driven to be retracted. At the same time, the motor of the driving mechanism 25 realizes the automatic locking of the lock tongue 28, and the lock tongue 28 locks the lock plate on the bellows, so that the gangway is in a retracted state and people cannot pass.

[0035] The automatic gangway for railway vehicles of this embodiment has an overall technical solution for automatic coupling and uncoupling, which changes the situation that the traditional gangway relies on manual operation and realizes intelligent control. Its extension and retraction docking principle is combined with the control system 31 through a precise mechanical structure to ensure the accuracy and stability of the coupling and uncoupling process. The automatic gangway can complete the automatic coupling and uncoupling operations in a certain curved line, which has strong adaptability to the complex line conditions in railway transportation.

[0036] The telescopic mechanism includes a servo motor 26 and an electric cylinder 27, and the electric cylinder 27 is connected to the servo motor 26 and driven by the servo motor 26. The telescopic mechanism plays a role in the connection and disconnection process of the automatic gangway of railway vehicles. When connecting, after the control system 31 issues a one-key connection command, the servo motor 26 drives the electric cylinder 27 to extend, pushing the bellows 2 to extend forward, ensuring that the front and rear gangways are in contact, and closing and docking according to the designed trajectory under the action of the guide pin 11. After the docking is completed, the electric cylinder 27 is automatically retracted. When unhooking, the one-key disconnection command causes the electric cylinder 27 to push out the bellows 2, and the servo motor 26 drives the bellows 2 to retract.

[0037] Specifically, the electric cylinder 27 is connected with a telescopic electromagnet 34, and the bellows is provided with a magnetic attraction plate 33. The telescopic process is achieved by the adsorption effect of the electromagnet on the magnetic attraction plate 33.

[0038] As an alternative, in addition to using the combination of the servo motor 26 and the electric cylinder 27, the telescopic mechanism can also use a lead screw drive or a screw drive to achieve its function.

[0039] The frame 22 includes a mounting frame 23 and a mounting frame 24, wherein the mounting frame 24 is disposed on the mounting frame 23, and the bellows 2 is mounted on the mounting frame 24. The frame 22 provides a basic framework for the entire structure to ensure its stability; the mounting frame 24 provides a mounting point for the bellows 2 to be firmly attached.

[0040] The control system 31 includes a communication module, a control module, an execution module and a detection module, wherein the execution module and the detection module are electrically connected to the telescopic mechanism and the lock drive motor 29, and the communication module, the execution module and the detection module are electrically connected to the control module. The modules of the control system 31 work together, the components are installed in the vehicle and are conveniently operated by the staff through the display screen, which effectively improves work efficiency.

[0041] The communication module communicates with the host computer via Ethernet, and can receive host computer instructions to drive related actions, and can also upload system information to ensure the interactive flow of information. The control module uses the detection module to accurately obtain the position information of the docking frame 4, and then relies on the execution module to accurately control the extension and locking of the docking frame 4, thereby ensuring the accurate execution of the through-channel connection and disconnection.

[0042] The control system 31 has three control modes, namely synchronous mode, local mode and opposite mode. In synchronous mode, the front and rear automatic gangways can be synchronously controlled by the single-end control system 31 to achieve efficient automatic coupling and uncoupling; the local mode focuses on the extension and retraction control of the front gangway on one side; the opposite mode is for the single-side operation of the opposite gangway.

[0043] In order to facilitate the motion control of the through-tunnel split structure 1 , the through-tunnel split structure 1 includes two sets of the driving mechanisms 25 .

[0044] The following are specific descriptions of each module of the control system 31: Control module: It is the main control chip and the matching control circuit used to realize the control function.

[0045] Execution module: It is the driving circuit of the upper and lower electric cylinders 27 and the telescopic electromagnet 34. The main control chip controls the electric cylinder to move the folding shed 2 according to the command of the system's own control button or Ethernet remote signal, thereby realizing the functions of connecting and unconnecting.

[0046] Detection module: It is the motor encoder and push rod position signal acquisition circuit. The system can collect the encoder pulse signal to calculate the rotation speed of the upper and lower electric cylinders 27, and then realize the synchronization function of the upper and lower electric cylinders 27 by adjusting the rotation speed; the upper and lower telescopic mechanisms are equipped with 2 position sensors, and the telescopic mechanisms are determined by collecting the position sensor signals.

[0047] Communication module: This module is connected to the vehicle-mounted host computer system through the Ethernet interface, receives the vehicle running speed in real time and sends the working conditions of the workshop access device to the host computer.

[0048] The bellows 2 includes a awning cloth 3, a docking frame 4, a car body connection frame 5, a sealing strip 6 and a guide pin 11. The docking frame 4 and the car body connection frame 5 are respectively arranged at both ends of the awning cloth 3. The car body connection frame 5 is connected to the frame 22. The sealing strip 6 and the guide pin 11 are arranged on the docking frame 4. The bellows 2 plays an important role in the automatic gangway system of railway vehicles. On the one hand, it provides a standing and passing space for passengers between two adjacent carriages, ensures that passengers can travel safely and conveniently between carriages, and improves the riding experience of passengers. On the other hand, the bellows 2 has good physical properties, which can effectively reduce the transfer of external noise and heat to the interior of the carriage, create a relatively quiet and comfortable riding environment for passengers, and also contribute to the temperature control and energy saving inside the train.

[0049] In the actual train coupling and uncoupling process, when coupling, the docking frame 4 in the bellows 2 is automatically unlocked under the command of the control system 31, and then extends forward under the action of the driving mechanism 25, cooperates with the bellows 2 of the opposite end of the gangway, and completes the docking action. After the docking is completed, the docking frame 4 of the bellows 2 is locked to ensure the stability of the coupling and the safe passage of personnel. When uncoupling, the docking frame 4 is unlocked, and the bellows 2 is retracted under the drive of the electric cylinder 27 and restored to the initial state, providing convenience for the train uncoupling operation. Its flexible telescopic performance and reliable connection function are important guarantees for the efficient operation of the automatic gangway.

[0050] The guide pins 11 play a role of precise guidance in the automatic gangway of railway vehicles. When the bellows 2 is extended to make the front and rear gangways contact each other, the guide pins 11 will guide the two gangways to close and dock according to the preset trajectory to ensure the accurate connection of the gangways and avoid misalignment.

[0051] The sealing strip 6 is mainly used for sealing, and can effectively prevent foreign matter such as dust and sand from entering the interior of the compartment. At the same time, it also plays the role of sound insulation and heat insulation.

[0052] In the prior art, as one arrangement of the guide pin 11 , the guide pin 11 is fixedly arranged on the docking frame 4 .

[0053] In this embodiment, in order to achieve the optimal arrangement of the guide pin 11, the sealing strip 6 is provided with a mounting hole 7 and a guide hole 9, the guide pin 11 is arranged in the mounting hole 7, and inserted into the guide hole 9 of the other through-channel split structure 1, and the guide pin 11 is detachably connected to the guide hole 9. After the connection is completed, the guide pin 11 is inserted into the guide hole 9 to achieve the connection between the two sealing strips 6. Since the guide pin 11 is arranged in the mounting hole and the guide hole, it is not fixedly connected to the docking frame 4, that is, it is completely in the two sealing strips 6, which is conducive to adapting to the deformation of the sealing strip 6, thereby facilitating the sealing strip 6 to produce a sufficiently good sealing effect.

[0054] Regarding the detachable connection between the guide pin 11 and the guide hole 9, a bolt can be set on the side of the guide hole 9 to fix it, or an auxiliary buckle can be set to achieve the detachable connection between the guide pin 11 and the guide hole 9. The detachable setting of the connection structure is mainly to facilitate the unhooking and connecting.

[0055] In this embodiment, the optimized setting mode is as follows: the guide pin 11 includes a guide cylinder 12 and a movable pin 19, the guide cylinder 12 is provided with a plurality of openings 13, and the plurality of openings 13 are evenly distributed around the circumference of the guide cylinder 12, a positioning block 14 is provided in the opening 13, the top side surface of the positioning block 14 is connected to the hole wall of the opening 13 through a steel sheet 15, a top abutment protrusion 16 is provided on the positioning block 14, a plurality of guide strips 17 arranged along the axial direction thereof are provided on the inner wall of the guide cylinder 12, the position of the opening 13 corresponds to the position of the guide strip 17, the movable pin 19 is provided in the guide cylinder 12, and the movable pin 19 is provided in the guide cylinder 12. A plurality of guide grooves 20 are provided on the surface of the movable pin 19, and the plurality of guide strips 17 and the plurality of guide grooves 20 are matched one by one. The guide groove 20 is provided with a limit groove 21 corresponding to the abutting protrusion 16. The guide cylinder 12 is fixedly arranged in the mounting hole 7 and inserted into the guide hole 9 of the other through-channel split structure 1. A first driving member 8 is provided in the mounting hole 7, and a second driving member 10 is provided in the guide hole 9. The first driving member 8 and the second driving member 10 are used to drive the movable pin 19 to move. The hole wall of the guide hole 9 is provided with a locking groove 32 corresponding to the plurality of locking blocks 14. Under the above structural setting, after the two through-channel split components are docked, the guide cylinder 12 is respectively inserted into the two sealing strips 6 in contact with each other, specifically located in the mounting hole 7 and the guide hole 9, to achieve the relative fixation of the two sealing strips 6, improve the stability of the sealing structure, and improve the sealing effect. Since both ends of the guide pin 11 are not in contact with the docking frame 4 and are completely in the two sealing strips 6, it is conducive to adapting to the deformation of the sealing strip 6, and it is conducive to the sealing strip 6 to produce a sufficiently good sealing effect, avoiding the sealing effect defects caused by the deformation of the sealing strip 6 due to the fixed setting. After the two sealing strips 6 are docked, the first driving member 8 or the second driving member 10 drives the movable pin 19 to move, so that the top protrusion 16 enters the limiting groove 21. Under the lifting effect of the limiting groove 21, the locking block 14 protrudes upward and enters the locking groove 32, thereby realizing the connection of the two sealing strips 6 through the guide pin 11, so that the sealing effect is improved.

[0056] Specifically, the first driving member 8 and the second driving member 10 are configured as electromagnets, and the movable pin 19 is made of magnetic material, so that the movable pin 19 can be moved left and right by turning the power on and off of the first driving member 8 and the second driving member 10, thereby realizing the motion control of the movable pin 19.

[0057] In order to ensure that the locking block 14 has a better locking effect in the connected state so that the two sealing strips 6 are tightly connected, a locking protrusion 18 is provided on the side of the locking block 14 .

[0058] In order to ensure that the guide pin 11 can accurately enter the guide hole 9 when the bellows 2 is docked, an arc chamfer is provided on the edge of the guide hole 9 to guide the entry of the guide pin 11.
