Description

Technical Field

[0001] The present invention belongs to the technical field of railway vehicle teaching equipment, and in particular relates to a multifunctional action simulation demonstration device and a demonstration method for a heavy-haul railway freight car coupler. Background Art

[0002] The railway freight car coupler is an important component for connecting railway freight cars. It undertakes the functions of providing traction and buffering, realizes the coupling between locomotives and vehicles or between vehicles, and is responsible for transmitting the traction force of the locomotive to the train, enabling the entire train to move forward synchronously. During the train operation, the coupler can absorb and mitigate the impact force generated between vehicles due to braking, acceleration, or passing through uneven road surfaces, protecting the vehicle structure from damage.

[0003] Currently, the common couplers in heavy-haul railways are type 13A, type 13B, type 16, and type 17 couplers. However, among the common couplers currently in use, only the type 16 coupler has achieved the rotation function and can be used with a car dumper to realize the uncoupled unloading operation. However, there is still no device that can demonstrate the rotation of the coupler and realize the simulation teaching of the car dumper unloading operation, enabling learners to fully understand the function and significance of the type 16 coupler.

[0004] During the manual inspection of train inspection technical operations, the couplers of the first and last vehicles in the train are inspected. When the above-mentioned faults are found, repair is carried out. However, due to the uneven professional qualities of personnel, the skills and sensitivities for detecting coupler faults are insufficient, resulting in the inability to detect and repair coupler faults in a timely manner.

[0005] In addition, teaching about couplers often causes difficulties due to the lack of dedicated vehicles, the teaching conditions not meeting the on-site production requirements, and the poor effect of the original training methods, with little gain in understanding the coupler functions, action principles, etc. Summary of the Invention

[0042] Referring to Figures 1 to 7 As shown, in the first aspect of this embodiment, a multi-functional action simulation demonstration device for the coupler of heavy-haul railway freight cars is provided, including a mechanical part system and a power system.

[0043] The machine part system includes an operation panel 3, a frame 1 and a coupler 7. The operation panel 3 is arranged on the top of the frame 1. A fixed seat 16 is arranged inside the frame 1.

The third group of transmission components is key-connected to the hook tongue pin a.

[0045] Specifically, referring to Figure 1 、 Figure 2 and Figure 3 As shown, the frame 1 is used to install various components of the demonstration device. A support seat 2 is connected to the bottom of the frame 1, and the support seat 2 is used to contact the ground. The operation panel 3 is arranged on the frame 1. The frame 1 has an accommodation space inside, and a rear door 12 is movably arranged on the side of the frame 1 away from the operation panel 3, which is convenient for overhauling various components inside the frame 1. The fixed seat 16 is arranged opposite to the coupler 7, and the coupler 7 is connected to the fixed seat 16 through the rotating shaft 28. The first group of transmission components can drive the rotating shaft 28 to rotate around the center of the fixed seat 16, so that the coupler 7 rotates. The coupler 7 in this embodiment adopts a 16-type heavy-haul train rotating coupler. The coupler 7 includes a coupler head, a coupler body 26 and a coupler tail. Referring to Figure 7 As shown, this coupler 7 includes a hook tongue pin a, a lower locking pin rod b, a lower locking pin c, a locking iron assembly d, a lower locking pin rotating shaft e, a hook tongue f and a hook tongue pushing iron g. The second group of transmission components is used to contact the lower locking pin rod b, and the lower locking pin rod b drives the lower locking pin c to lift the locking iron assembly d, so as to complete the unlocking and fully opening actions. The third group of transmission components is key-connected to the hook tongue pin a, and the hook tongue pin a and the hook tongue f are connected through a fastening screw 11, so as to complete the locking action.

[0046] The overall dimensions of this device are 1300×1000×1600 mm in length, width and height, which is only 1 / 12 of the actual volume of the vehicle. Compared with the in-vehicle teaching, this device is not restricted by time and space, and is convenient for the installation and movement of teaching molds.

[0047] Furthermore, referring to Figure 2 and Figure 4As shown in the figure, the first set of transmission components includes a first stepping motor 20 and a transmission chain 18. Both ends of the transmission chain 18 are respectively sleeved on the output shaft of the first stepping motor 20 and a toothed disc 27. Specifically, one end of the rotating shaft 28 away from the fixed seat 16 is connected to the hook body 26. The output end of the first stepping motor 20 is connected with a speed reducer 21. The output shaft of the speed reducer 21 is horizontally arranged. One end of the transmission chain 18 is sleeved on the output shaft of the speed reducer 21, and the other end is sleeved on the outer circumference of the toothed disc 27. The first stepping motor 20 drives the transmission chain 18 to move, the transmission chain 18 drives the toothed disc 27 to rotate, and the toothed disc 27 drives the rotating shaft 28 to rotate, thereby driving the hook body 26 to rotate, realizing the rotation of the coupler 7 with the horizontal central axis of the rotating shaft 28 as the rotation center; Refer to Figure 5 As shown in the figure, the second set of transmission components includes a second stepping motor 24 and a rack 25. The gear 30 inside the second stepping motor 24 is meshed with the rack 25, and a pressing bearing 29 is arranged on the rack 25. The pressing bearing 29 ensures gapless meshing between the gear 30 and the rack 25, reduces the gap during the transmission process, improves the transmission accuracy and stability, and at the same time reduces the wear between the gear 30 and the rack 25, extending the service life of the gear 30 and the rack 25. A hook opening frame 6 is movably arranged on one side of the frame 1 close to the coupler 7. The rack 25 drives the hook opening frame 6 to move towards the lower locking pin rod b under the drive of the second stepping motor 24. Specifically, when the second stepping motor 24 works, it drives the gear 30 to rotate, the gear 30 drives the rack 25 to make a linear motion, the rack 25 moves towards the coupler 7, thereby pushing the hook opening frame 6, and the hook opening frame 6 pushes the lower locking pin rod b, thus completing the unlocking and full opening actions; Refer to Figure 6 As shown in the figure, the third set of transmission components is a third stepping motor 10. The third stepping motor 10 is arranged below the coupler head, and the output shaft of the third stepping motor 10 is arranged along the longitudinal direction of the coupler head. The hook tongue pin a and the hook tongue f are connected into one body by fastening screws. The output shaft of the third stepping motor 10 drives the hook tongue pin a and the hook tongue f to rotate through key transmission. The hook tongue pin a can overcome the friction force inside the coupler 7 to complete retraction, and at the same time the hook tongue f retracts inward, realizing the locking action; Three motor drivers 19 are arranged inside the frame 1, and the three motor drivers 19 are respectively electrically connected to the first stepping motor 20, the second stepping motor 24 and the third stepping motor 10.

[0048] The three independent sets of transmission components enable the number of times of single coupler function demonstrations to be unlimited. At the same time, the full-process demonstration of multiple coupler functions and the demonstration of single coupler functions do not interfere with each other, which is convenient for students to repeat watching and learning.

[0049] The device further includes an electric control system, which includes a power supply box module 17, a power switch 22 and a rectifier transformer 23 arranged in the frame 1. The power switch 22 is connected to an external power supply. The rectifier transformer 23 is arranged side by side with the power switch 22, and the output end of the rectifier transformer 23 is electrically connected to the input end of the power switch 22. All three motor drivers 19 are electrically connected to the power switch 22. The power supply box module 17 includes three power supply boxes, which are respectively electrically connected to the three motor drivers 19 to provide power for the three motor drivers 19.

By using the electric control system as the power source hub of the entire device, this device realizes the function of accurate positioning, has the autonomy of automatic demonstration and automatic explanation, and realizes the fragmentation and autonomy of training.

[0050] Further, it further includes a remote control system, which includes a remote control device 14, a remote controller, and a programmer 15. The remote control device 14 and the programmer 15 are both arranged in the frame 1. The remote controller is used to transmit the status signal of the coupler 7 to the remote control device 14. The remote control device 14 transmits the status signal to the programmer 15, and the programmer 15 is used to send an instruction to the motor driver 19. Specifically, the remote control system is the center of the intelligent operation of this device.

The programmer 15, the first stepping motor 20, the second stepping motor 24, and the third stepping motor 10 are connected to the remote control device 14. The switch of the remote control device 14 is controlled by an external remote controller, so as to replace the control switch 4 to complete different actions. By pressing the rotation position button on the remote controller, the remote controller sends a rotation signal to the remote control device 14. The remote control device 14 connects the coupler rotation switch and transmits the rotation signal to the programmer 15 to execute the coupler rotation program. The programmer 15 sends a working instruction to the motor driver connected to the first stepping motor 20, and the motor driver drives the first stepping motor 20 to execute the rotation program according to the received working instruction.

By pressing the locking position button on the remote controller, the remote control device 14 connects the locking position switch and transmits the locking signal to the programmer 15 to execute the locking program. The programmer 15 sends a working instruction to the motor driver connected to the third stepping motor 10, and the motor driver executes the locking program according to the received working instruction.

[0051] Refer to Figure 2As shown in the figure, since it is impossible to deeply understand the action meaning of each component of the coupler 7 in different states only by action demonstration, this device is also provided with an interactive experience system. The interactive experience system is arranged on the operation panel 3 and includes a display 5, a speaker 13 and four control switches 4. The four control switches 4 are all electrically connected to a programmer 15 and a remote control device 14.

A socket 8 is also arranged inside the frame 1, and the socket 8 supplies power to the display 5. By importing the videos explaining each component of the coupler and the coupler in four states into the display 5, students can learn through the synchronous explanation of videos and physical objects, understand the common fault-prone parts of the coupler and the possible impact on the coupler function after a fault occurs. Moreover, the display 5 is electrically connected to the speaker 13, enabling students to receive information synchronously through vision, hearing and touch, enhancing the teaching function of this device.

[0052] To facilitate the observation of the actions of each component of the coupler inside the coupler cavity, this device is also provided with a lighting component. The lighting component is arranged inside the coupler 7, and the top and side parts of the coupler cavity of the coupler 7 are hollowed out. The lighting component includes a plurality of LED lights. The plurality of LED lights are arranged inside the coupler cavity, and the light is scattered from the inside to the outside to realize the lighting of each component inside the coupler cavity, facilitating students' observation. To further facilitate students' observation of each component of the coupler, the hook tongue pin a, the lower locking pin rod b, the lower locking pin c, the locking iron assembly d, the lower locking pin rotating shaft e, the hook tongue f and the hook tongue pusher g are all marked with different colors, thereby enhancing the visual effect.

[0053] Refer to Figure 7 As shown in the figure, in the second aspect of this embodiment, a method for simulating and demonstrating the multi-functional actions of a heavy-haul railway freight car coupler is provided. It is completed based on the above-mentioned heavy-haul railway freight car coupler multi-functional action simulation demonstration device, including four states: rotation position, unlocking position, full opening position and locking position. Specifically, it includes the following steps:

[0054] S1. Rotating position: The first stepping motor 20 drives the transmission chain 18 to rotate. The transmission chain 18 drives the rotating shaft 28 to rotate, and the rotating shaft 28 drives the coupler 7 to rotate. Specifically, the control program of the programmer 15 drives the first stepping motor 20 to work. The first stepping motor 20 drives the transmission chain 18 to move, the transmission chain 18 drives the gear disk 27 to rotate, and the gear disk 27 drives the rotating shaft 28 to rotate, thereby driving the coupler body 26 to rotate, realizing the rotation of the coupler 7 with the horizontal central axis of the rotating shaft 28 as the rotation center;

[0055] S2. Unlocking position: Refer to Figure 7 (B). The second stepping motor 24 drives the rack 25 to push the hook opening frame 6. Specifically, the second stepping motor 24 works to drive the gear 30 to rotate. The gear 30 drives the rack 25 to move linearly. The rack 25 moves towards the coupler 7, thereby pushing the hook opening frame 6. The hook opening frame 6 contacts the lower locking pin rod b. The lower locking pin rod b drives the lower locking pin c to rotate into the coupler 7 around the lower locking pin rotating shaft e. The lower locking pin c disengages from the anti - jumping position and drives the locking iron assembly d to move upward. The locking iron assembly d passes over the tail of the hook tongue f. Since the head of the locking iron assembly d is heavier, the locking leg of the locking iron assembly d deflects backward. The locking leg of the locking iron assembly d is lapped on the hook tongue push iron g, and the hook tongue push iron g cannot fall, thereby enabling the coupler 7 to reach the unlocking position. At the same time, the second stepping motor 24 rotates in the reverse direction, the rack 25 retracts to the initial position, and the hook opening frame 6 returns to the initial position;

[0056] S3. Fully open position: Refer to Figure 7 (C). The second stepping motor 24 drives the rack 25 to push the hook opening frame 6. When the hook opening frame 6 rotates to the maximum stroke, the hook opening frame 6 contacts the lower locking pin rod b. The lower locking pin rod b drives the lower locking pin c to rotate into the coupler 7 around the lower locking pin rotating shaft e. The lower locking pin c disengages from the anti - jumping position and drives the locking iron assembly d to move upward, causing the leg of the locking iron assembly d to rotate backward and push the hook tongue push iron g. The hook tongue push iron g rotates to contact the hook tongue f and pushes the tail of the hook tongue f. The hook tongue f rotates with the hook tongue pin a as the center line, and the hook tongue f opens to the fully open position;

[0057] S4. Locking position: Refer to Figure 7 (A). The control program of the programmer 15 drives the output shaft of the third stepping motor 10 to rotate. The third stepping motor 10 drives the hook tongue pin a and the hook tongue f to rotate into the coupler 7. The tail of the hook tongue f rotates into the hook locking cavity. The locking iron assembly d moves downward due to its own weight. The rear - sitting locking surface and the side - sitting locking surface of the locking iron assembly d respectively sit on the locking seat of the hook tongue push iron g and the hook locking bearing platform on the side of the tail of the hook tongue f, causing the locking iron assembly d to be stuck between the side of the tail of the hook tongue f and the side wall surface of the hook locking cavity, thereby restricting the rotation of the hook tongue f.

[0058] To achieve human-machine interaction, the demonstration method further includes human-machine interaction display, in which a coupler teaching video is imported into the display 5. This teaching video demonstrates the explanation of the type-16 coupler and common faults. By opening the system, it intelligently explains the names of the type-16 coupler and its accessories, the rotation of the coupler, the unlocking position, the fully open position, the locking position, the operating principles, the prone-to-fault parts and fault characteristics of the type-16 coupler and its accessories, so as to realize autonomous learning.

[0059] Of course, a 3D real-scene cloud of the coupler can also be imported into the interactive experience system. The 3D real-scene cloud of the coupler demonstrates the cross-section of the coupler. By changing the positions of the assembly axes X, Y, and Z, the 3D coupler can be analyzed in the corresponding directions to view the internal structure of the coupler 7; the 3D real-scene cloud of the coupler can also perform an explosion display. By clicking on the coupler or its accessories, all vehicle accessories are decomposed into the smallest units, and at the same time, the smallest unit vehicle accessories can be dynamically displayed with a 360° rotation and detailed structure and function explanations; the 3D real-scene cloud of the coupler can also explain the working principle. By clicking on the rotation, unlocking position, fully open position, and locking position in sequence, the 3D coupler performs corresponding simulation animations; double-clicking on the coupler and its accessories can display the prone-to-fault parts and fault characteristics explanations, and at the same time, illustrate the hazards to the operation of heavy-haul trains.

[0060] In the above demonstration method, after the coupler 7 is unlocked, the second stepping motor 24 returns to its initial state. At this time, the coupler tongue f is not opened and cannot be locked. During the fully open position demonstration, since the second stepping motor 24 is driven by the rack 25 and cannot provide enough instantaneous thrust to push the coupler tongue f to the fully open position, after unlocking is completed, the third stepping motor 10 is automatically started. The third stepping motor 10 rotates and drives the coupler tongue f to the open position, so as to facilitate the coupler 7 to complete locking.

[0061] The heavy-haul railway freight car coupler multi-functional action simulation demonstration device provided in this embodiment has two observation functions of a physical coupler and a 3D coupler. The 3D coupler can observe the coupler at any angle, and at the same time, the viewing angle can be focused on a certain point and enlarged or reduced at will. Through the interactive experience method combining the physical object and the 3D, and the human-machine interconnection method, it realizes the intelligent control of the coupler rotation and the demonstration of the three states of action. At the same time, the display 5 synchronously displays the simulated effect diagrams of each state of the coupler for slow-play explanation, combines the internal structure of the coupler with the dynamic demonstration, realizes the visualization of the cross-section and the dynamic demonstration of the teaching mold, enables the trainees to simply and intuitively understand the internal cooperation principle and the movement track of the coupler, and easily and understandably understand and master the composition structure and the action principle of the coupler.
