Description

Technical Field

[0001] The present invention relates to the technical field of railway equipment, and in particular to an electric coupling and disconnecting device and method for railway vehicles. Background Art

[0002] In the railway transportation system, the vehicle coupling and clutching operation is an important part of train marshaling and unmarshaling operations, and its efficiency and reliability directly affect the overall efficiency of railway transportation. With the continuous expansion of railway transportation scale and the gradual increase in transportation speed, the performance requirements for coupling and clutching devices are becoming increasingly stringent.

[0003] Traditional railway vehicle uncoupling and clutching devices mostly rely on manual operation, which is not only labor-intensive but also inefficient. Workers need to frequently shuttle between train carriages to manually complete the uncoupling action, which is time-consuming and labor-intensive during large-scale marshaling operations, seriously affecting operational efficiency. At the same time, there is a lack of effective automatic maintenance functions. Key components such as car pins are easily damaged due to wear after frequent use, but they cannot be lubricated and maintained in time, increasing equipment maintenance costs and downtime.

[0016] As a further description of the above technical solution:

[0017] The transmission assembly includes a driven shaft rotatably arranged on the inner wall of the second mounting shell and a second gear sleeved on the surface of the driven shaft. A ratchet and pawl mechanism is provided at the connection between the second gear and the driven shaft for limiting the forward rotation of the driven shaft. A second incomplete gear is fixedly provided on the surface of the operating rod through a second clamp. The second incomplete gear and the second gear are meshed with each other. A ratchet and pawl mechanism is also provided at the connection between the driven shaft and the inner wall of the second mounting shell for limiting the reverse rotation of the driven shaft.

[0020] As a further description of the above technical solution:

[0021] A fixed shell is arranged at one end of the rotating plate, and a sealing cover for covering the fuel injection nozzle is hingedly arranged at the upper end of the fixed shell through a reset hinge, and an edge of one side of the sealing cover is in a bevel shape.

[0022] As a further description of the above technical solution:

[0023] The upper ends of the first installation shell and the second installation shell are both provided with detachable top covers.

[0024] The present invention also proposes a method for using the electric coupling and clutch device for railway vehicles, comprising the following steps:

[0025] Step 1: On the one hand, the staff can start the motor to drive the first gear to rotate, and through the meshing action of the first gear and the first incomplete gear tooth block, drive the driving shaft to rotate, and then drive the operating rod to rotate under the cooperation of the second docking block and the first docking block. On the other hand, the staff can manually operate to rotate the operating rod;

[0026] Step 2: The operating lever is rotated to pull the pin upward through the side hook, the connecting ring and the connecting ear, thereby opening the coupler;

[0027] Step 3: When the operating lever rotates, the driven shaft is driven to rotate under the meshing action of the second incomplete gear and the second gear tooth block. By setting the gear ratio of the second incomplete gear and the second gear, each time the operating lever is rotated, the second gear is driven to deflect 90°, the rotation of the driven shaft drives the eccentric wheel to deflect, and the rotation of the eccentric wheel drives the rotating wheel to revolve, so that each time the operating lever is rotated four times, the fixed frame is lifted up once under the cooperation of the rotating wheel and the fixed frame;

[0028] The fourth step is that the fixed frame moves upward to drive the lifting plate to move upward. The upward movement of the lifting plate drives the piston plate to move upward through the piston rod. Since the electromagnetic three-way valve is energized, the oil storage tank and the piston tube are in a connected state. At the same time, the upward movement of the lifting plate produces a relative displacement with the rotating sleeve, and then the rotating sleeve is rotated under the cooperation of the protrusion and the guide groove. The guide groove includes a spiral groove and a vertical groove. The protrusion slides along the spiral groove to drive the rotating sleeve to rotate. The rotation of the rotating sleeve drives the rotating plate to deflect. The deflection of the rotating plate drives the fixed shell and the sealing cover to deflect synchronously. When the sealing cover is separated from the lower end surface of the second mounting shell, the sealing cover is deflected and opened under the action of the reset hinge, so that the fuel injector is exposed to the outside until the fuel injector faces the car pin.

[0029] Step 5. As the lifting plate moves upward, the squeeze on the travel switch will gradually be released. When the fuel injector faces the pin, the lifting plate continues to move upward to release the squeeze on the travel switch. At this time, the electromagnetic three-way valve is powered off, so that the piston tube and the oil pipe are connected. Then the upward movement of the piston plate will push the lubricating oil in the piston tube to the oil pipe and spray it out from the fuel injector.

[0030] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0031] In the present invention, by setting a driving component, the operating rod has two driving modes: manual and electric. Manual operation is suitable for emergency situations or motor failures to ensure the emergency needs of hook removal operations; electric operation is driven by a motor, which reduces the labor intensity of the staff, and the operation is more convenient and efficient, thereby improving the efficiency of hook removal.

[0032] In the present invention, by providing the first docking block, the second docking block, the first limit rod, the second limit rod and the limit piece, the rotation angle of the operating lever can be accurately limited when the hook is manually or electrically unhooked, ensuring that the position of the coupler is accurately opened and closed, and the hook can be lifted and dropped into place, avoiding safety accidents caused by improper operation.

[0033] In the present invention, by arranging a transmission assembly, an oil delivery assembly and an oil outlet assembly, after the operating lever is rotated several times, the eccentric wheel lifts the fixed frame, drives the lifting plate to rise, and then triggers a series of actions, thereby realizing automatic lubrication of the car pin connection during the hook-off process, extending the service life of the car pin and reducing maintenance costs.

[0034] In the present invention, by providing a fixed shell and a sealing cover, the sealing cover automatically opens when the rotating plate is deflected and opened, exposing the fuel injector to the outside and preparing for subsequent fuel injection. When the rotating plate is deflected and closed, the sealing cover is squeezed and closed to cover the fuel injector, thereby preventing the fuel injector from being always exposed to the external environment and causing clogging of the fuel injector.

[0049] like Figure 1-Figure 12 As shown, an electric coupling and clutch device for railway vehicles comprises a mounting plate 1 and a coupler 2 with a pin 3, the mounting plate 1 and the coupler 2 are respectively fixedly mounted on the carriage, and a through hole matched with the coupler 2 is formed on the mounting plate 1, an operating rod 6 is rotatably arranged on one side of the mounting plate 1 through a support plate 46, the number of the support plates 46 is multiple and linearly distributed, the support plate 46 is fixed to the mounting plate 1 by bolts or welding, the operating rod 6 is rotatably connected to the support plate 46 by a bearing, a side hook 12 is fixedly arranged on the surface of the operating rod 6, a connecting ring 4 is sleeved on the outer side of the side hook 12, one end of the side hook 12 is welded and fixed to the surface of the operating rod 6, and the other end of the side hook 12 is in a suspended state, so that the connecting ring 4 is sleeved on the side hook 12, the upper end of the pin 3 is connected with a connecting ear matched with the connecting ring 4, and a driving component for driving the operating rod 6 to rotate is arranged on one side of the mounting plate 1, so that the driving modes of the operating rod 6 are manual and electric;

[0050] It also includes an oil storage tank 19 with an oil filling pipe 20, and a sealing plug is provided at the end of the oil filling pipe 20. Lubricating oil is pre-injected into the oil storage tank 19 through the oil filling pipe 20 to prepare for subsequent use. A second mounting shell 7 is provided on the other side of the mounting plate 1, and the second mounting shell 7 is fixed to the mounting plate 1 by bolts or welding. The oil storage tank 19 is fixedly connected to the inner wall of the second mounting shell 7, and the oil storage tank 19 and the second mounting shell 7 are fixed by bolts or welding. An oil outlet assembly for injecting oil into the car pin 3 is rotatably provided at the lower end of the second mounting shell 7, and an oil delivery assembly for delivering oil to the oil outlet assembly is provided on one side of the oil storage tank 19. The lubricating oil inside the oil storage tank 19 is transported to the oil outlet assembly through the oil delivery assembly, and the operating rod 6 passes through the side wall of the second mounting shell 7 and is rotatably connected to the second mounting shell 7 through a bearing, and a transmission assembly matching the operating rod 6 is provided inside the second mounting shell 7.

[0051] Further, the driving assembly includes a first mounting shell 5 fixedly arranged on the surface of the mounting plate 1 and a motor 8 fixedly arranged inside the first mounting shell 5. The first mounting shell 5 is fixed to the mounting plate 1 by bolts or welding, and the motor 8 is fixedly connected to the first mounting shell 5 through a mounting seat. A driving shaft 18 is rotatably arranged inside the first mounting shell 5. One end of the operating rod 6 movably penetrates into the first mounting shell 5 and is provided with a first docking block 16. One end of the driving shaft 18 is provided with a second docking block 17 that matches the first docking block 16. The ends of the first docking block 16 and the second docking block 17 that are docked are both formed with a notch groove (refer to the attached manual). Figure 3 As shown), a first incomplete gear 13 is fixedly provided on the surface of a driving shaft 18 through a second clamp 14, and a first gear 9 meshing with the first incomplete gear 13 is provided at the output end of the motor 8. Since the motor 8 has a self-locking function, on the one hand, when a staff member manually drives the operating lever 6 to rotate, the cooperation of the first docking block 16 and the second docking block 17 will limit the degree of deflection of the operating lever 6, that is, the deflection of the operating lever 6 pulls the pin 3 upward through the side hook 12, the connecting ring 4 and the connecting ear, and then the coupler 2 is manually unfolded. On the other hand, when the motor 8 is started to drive the first gear 9 to rotate, the first gear 9 is meshed with the tooth block of the first incomplete gear 13, which drives the driving shaft 18 to rotate. Under the transmission of the first docking block 16 and the second docking block 17, the rotation of the driving shaft 18 drives the operating lever 6 to rotate, that is, the coupler 2 is unfolded by electric means.

[0052] Further, the surface of the drive shaft 18 is fixed with a first limiting rod 43 and a second limiting rod 44 through two first clamps 11, and the first limiting rod 43 and the second limiting rod 44 are staggered. The first mounting shell 5 is fixed with limiting members 10 that match the first limiting rod 43 and the second limiting rod 44. When the coupler 2 is unfolded in an electric manner, the rotation of the drive shaft 18 will drive the first limiting rod 43 and the second limiting rod 44 to deflect synchronously (refer to the appendix of the manual). Figure 4), which will cause the second limit rod 44 to abut against one of the limit members 10, thereby limiting the rotation of the drive shaft 18, that is, limiting the rotation of the operating rod 6, and achieving the effect of lifting the hook into place. Conversely, when the drive shaft 18 rotates in the opposite direction, the first limit rod 43 will abut against the other limit member 10, achieving the effect of dropping the hook into place.

[0053] Furthermore, the oil delivery assembly includes a piston tube 29 and an electromagnetic three-way valve 28 arranged on one side of the oil storage tank 19. The upper end of the piston tube 29 is fixedly provided with a pipe mouth and is connected to one end of the electromagnetic three-way valve 28. When the electromagnetic three-way valve 28 is energized, the piston tube 29 and the oil storage tank 19 are in a state of mutual communication. The other end of the electromagnetic three-way valve 28 is fixedly connected with an oil delivery pipe 27. When the electromagnetic three-way valve 28 is de-energized, the piston tube 29 and the oil delivery pipe 27 are in a state of mutual communication. A piston plate 30 is slidably provided inside the piston tube 29, and a piston rod is fixedly provided at the lower end of the piston plate 30. A lifting plate 23 is elastically connected inside the second mounting shell 7. The upper end surface of the lifting plate 23 and the lower end surface of the piston tube 29 are connected by a first spring 31. The lower end of the piston rod is fixedly connected to the upper end of the lifting plate 23, and a fixing frame 22 is provided at the upper end of the lifting plate 23.

[0054] Further, the oil outlet assembly includes a rotating plate 40 and a rotating sleeve 32 fixedly arranged on the upper end of the rotating plate 40, a port ring is rotatably arranged on the upper end of the rotating sleeve 32, the lower end surface of the port ring is connected to the upper end surface of the lifting plate 23 by a second spring 33, the surface of the rotating sleeve 32 is rotatably connected to the lower end of the second mounting shell 7 by a bearing, an oil spray nozzle 45 is arranged at one end of the rotating plate 40, and a connecting pipe 42 is connected to the input end of the oil spray nozzle 45, the connecting pipe 42 is connected to the oil delivery pipe 27 through a rotating joint 41, the connecting pipe 42 is L-shaped and one end is coaxially distributed with the rotating sleeve 32, a through opening matching with the rotating sleeve 32 is formed on the surface of the lifting plate 23, a convex block 38 is fixedly arranged on the inner wall of the through opening, a guide groove 39 matching with the convex block 38 is formed on the surface of the rotating sleeve 32, a travel switch 24 matching with the lifting plate 23 is arranged on the inner bottom surface of the second mounting shell 7, a controller is arranged on the inner wall of the second mounting shell 7, and the travel switch 24 is connected to the electromagnetic three-phase transmission oil pump 27. The through valves 28 are electrically connected to the controller respectively. As the lifting plate 23 starts to move upward, the cooperation of the protrusion 38 and the guide groove 39 will cause the rotating plate 40 to deflect, thereby causing the oil nozzle 45 to face the side of the turning pin 3. Then, as the lifting plate 23 moves further upward, the cooperation of the protrusion 38 and the guide groove 39 will not cause the rotating sleeve 32 to deflect, that is, the rotating plate 40 will not deflect. In the process of further upward movement of the lifting plate 23, the squeezing of the travel switch 24 will be gradually released, thereby causing the electromagnetic three-way valve 28 to be powered off. At this time, the piston tube 29 and the oil delivery pipe 27 are in a state of mutual communication. Then, the lifting plate 23 moves upward and drives the piston plate 30 to move through the piston rod, so that the lubricating oil inside the piston tube 29 passes through the electromagnetic three-way valve 28, the oil delivery pipe 27 and the connecting pipe 42 in turn, and then is sprayed out from the oil nozzle 45, which has the effect of lubricating the connection of the turning pin 3.

[0055] Further, the transmission assembly includes a driven shaft 35 rotatably arranged on the inner wall of the second mounting shell 7 and a second gear 21 sleeved on the surface of the driven shaft 35. A ratchet pawl mechanism 34 is provided at the connection between the second gear 21 and the driven shaft 35 for limiting the positive rotation of the driven shaft 35. A second incomplete gear 15 is fixedly provided on the surface of the operating rod 6 through a second clamp 14. The second incomplete gear 15 and the second gear 21 are meshed with each other. A ratchet pawl mechanism 34 is also provided at the connection between the driven shaft 35 and the inner wall of the second mounting shell 7 for limiting the reverse rotation of the driven shaft 35. The other end of the driven shaft 35 is provided with a The extrusion piece of the lifting fixed frame 22 drives the second incomplete gear 15 to rotate as the operating lever 6 rotates. The second incomplete gear 15 drives the second gear 21 to rotate through the meshing of the tooth block. The rotation of the second gear 21 drives the driven shaft 35 to rotate under the transmission of the ratchet pawl mechanism 34. The rotation of the driven shaft 35 drives the extrusion piece to deflect, so that the extrusion piece gradually approaches the fixed frame 22. By setting the tooth ratio of the second incomplete gear 15 and the second gear 21, it is used to control the operation of the operating lever 6 for several times, so that the extrusion piece completes one extrusion of the fixed frame 22, that is, completes one oil injection lubrication operation.

[0056] Furthermore, the extrusion member includes an eccentric wheel 36 fixedly provided with the end of the driven shaft 35, and a rotating wheel 37 for extruding the fixed frame 22 is rotatably provided on the surface of the eccentric wheel 36. By providing the rotating wheel 37, rolling contact is made between the rotating wheel 37 and the fixed frame 22, thereby effectively avoiding friction resistance.

[0057] Furthermore, a fixed shell 26 is provided at one end of the rotating plate 40, and a sealing cover 25 for covering the fuel injector 45 is hingedly provided at the upper end of the fixed shell 26 through a reset hinge. The edge of one side of the sealing cover 25 is in a bevel shape. When the sealing cover 25 is closed, the fuel injector 45 is in a closed space, so that the fuel injector 45 is not always exposed to the external environment, resulting in clogging of the fuel injector 45. When the lifting plate 23 moves upward, that is, when the rotating plate 40 is deflected so that the fuel injector 45 is deflected toward the side of the pin 3, during the deflection process, the sealing cover 25 is closed. The sealing cover 25 gradually separates from the lower end surface of the second mounting shell 7, and then under the action of the reset hinge, the sealing cover 25 is deflected and opened, thereby exposing the fuel injection nozzle 45 to the outside, preparing for the subsequent fuel injection to the connection between the pin 3 and the pin 3. Conversely, when the lifting plate 23 moves downward, the rotating plate 40 will be deflected in the opposite direction. As the rotating plate 40 deflects in the opposite direction, the inclined surface on one side of the sealing cover 25 will contact the lower end surface of the second mounting shell 7, and then as the rotating plate 40 continues to deflect in the opposite direction, the sealing cover 25 will gradually close.

[0058] Furthermore, a detachable top cover is provided on the upper end of the first installation shell 5 and the second installation shell 7 , and the top cover is fixed by bolts. The staff can remove the top cover to inspect the inside of the first installation shell 5 and the second installation shell 7 .

[0059] The present invention also proposes a method for using the electric coupling and clutch device for railway vehicles, comprising the following steps:

[0060] Step 1: On the one hand, the staff can start the motor 8 to drive the first gear 9 to rotate, and through the meshing action of the first gear 9 and the first incomplete gear 13, the drive shaft 18 is driven to rotate, and then the second docking block 17 and the first docking block 16 are engaged to drive the operating rod 6 to rotate. On the other hand, the staff can manually operate to rotate the operating rod 6;

[0061] Step 2: The operating rod 6 is rotated to pull the pin 3 upward through the side hook 12, the connecting ring 4 and the connecting ear, thereby opening the coupler 2;

[0062] Step 3: When the operating rod 6 rotates, the driven shaft 35 is driven to rotate under the meshing action of the second incomplete gear 15 and the second gear 21. By setting the gear ratio of the second incomplete gear 15 and the second gear 21, each time the operating rod 6 rotates, the second gear 21 is driven to deflect 90°, the driven shaft 35 rotates to drive the eccentric wheel 36 to deflect, and the eccentric wheel 36 rotates to drive the rotating wheel 37 to revolve, so that each time the operating rod 6 rotates four times, the rotating wheel 37 cooperates with the fixing frame 22, so that the fixing frame 22 is lifted up once;

[0063] Step 4: The fixing frame 22 moves upward to drive the lifting plate 23 to move upward. The lifting plate 23 moves upward to drive the piston plate 30 to move upward through the piston rod. Since the electromagnetic three-way valve 28 is energized, the oil storage tank 19 and the piston tube 29 are in a connected state. At the same time, the lifting plate 23 moves upward to produce relative displacement with the rotating sleeve 32, and then the rotating sleeve 32 rotates under the cooperation of the protrusion 38 and the guide groove 39. The guide groove 39 includes a spiral groove and a vertical groove. The protrusion 38 slides along the spiral groove to drive the rotating sleeve 32 to rotate. The rotation of the rotating sleeve 32 drives the rotating plate 40 to deflect. The deflection of the rotating plate 40 drives the fixed shell 26 and the sealing cover 25 to deflect synchronously. When the sealing cover 25 is separated from the lower end surface of the second mounting shell 7, the sealing cover 25 is deflected and opened under the action of the reset hinge, so that the fuel injection nozzle 45 is exposed to the outside until the fuel injection nozzle 45 faces the car pin 3;

[0064] Step five, while the lifting plate 23 moves upward, the squeeze on the travel switch 24 will be gradually released. When the oil nozzle 45 faces the pin 3, the lifting plate 23 continues to move upward to release the squeeze on the travel switch 24. At this time, the electromagnetic three-way valve 28 is powered off, so that the piston tube 29 and the oil pipe 27 are in a connected state. Then the piston plate 30 moves upward to push the lubricating oil in the piston tube 29 to the oil pipe 27 and spray it out from the oil nozzle 45.

[0065] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

10. A method for using a railway vehicle electric coupling and release device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: On the one hand, the staff can start the motor (8) to drive the first gear (9) to rotate, and through the meshing action of the first gear (9) and the first incomplete gear (13) tooth block, drive the drive shaft (18) to rotate, and then drive the operating rod (6) to rotate under the cooperation of the second docking block (17) and the first docking block (16). On the other hand, the staff can manually operate to rotate the operating rod (6); Step 2: The operating rod (6) is rotated to pull the pin (3) upward through the side hook (12), the connecting ring (4) and the connecting ear, thereby opening the hook (2); Step 3: When the operating rod (6) rotates, the driven shaft (35) is driven to rotate under the meshing action of the second incomplete gear (15) and the second gear (21). By setting the gear ratio of the second incomplete gear (15) and the second gear (21), each time the operating rod (6) rotates once, the second gear (21) is driven to deflect by 90 degrees, the rotation of the driven shaft (35) drives the eccentric wheel (36) to deflect, and the rotation of the eccentric wheel (36) drives the rotating wheel (37) to revolve, so that each time the operating rod (6) rotates four times, the rotating wheel (37) cooperates with the fixing frame (22), so that the fixing frame (22) is lifted upward once; Step 4: The fixing frame (22) moves upward to drive the lifting plate (23) to move upward. The lifting plate (23) moves upward to drive the piston plate (30) to move upward through the piston rod. Since the electromagnetic three-way valve (28) is energized, the oil storage tank (19) and the piston tube (29) are in a connected state. At the same time, the lifting plate (23) moves upward to generate relative displacement with the rotating sleeve (32). Then, under the cooperation of the protrusion (38) and the guide groove (39), the rotating sleeve (32) rotates, and the guide groove (39) comprises a spiral groove and a vertical groove, the protrusion (38) slides along the spiral groove, driving the rotating sleeve (32) to rotate, the rotating sleeve (32) rotates to drive the rotating plate (40) to deflect, the deflection of the rotating plate (40) drives the fixed shell (26) and the sealing cover (25) to deflect synchronously, when the sealing cover (25) is separated from the lower end surface of the second mounting shell (7), the sealing cover (25) is deflected and opened under the action of the reset hinge, so that the fuel injection nozzle (45) is exposed to the outside, until the fuel injection nozzle (45) faces the pin (3); Step 5: When the lifting plate (23) moves upward, the pressure on the travel switch (24) is gradually released. When the oil nozzle (45) faces the pin (3), the lifting plate (23) continues to move upward to release the pressure on the travel switch (24). At this time, the electromagnetic three-way valve (28) is powered off, so that the piston tube (29) and the oil delivery pipe (27) are in a connected state. Then, the piston plate (30) moves upward to push the lubricating oil in the piston tube (29) to the oil delivery pipe (27) and spray it out from the oil nozzle (45).
