Description
Technical Field
[0001] The present invention relates to the technical field of railway freight cars, and particularly relates to a railway freight car coupler device, method and railway freight car. Background Art
[0002] The statements herein only provide background art related to the present invention and do not necessarily constitute prior art.
[0003] At present, there are various railway freight car couplers with different volumes and structures, which makes it impossible to couple different couplers. The railway standards used in different regions are also different, resulting in poor traffic between different regions. Railway freight cars are also not the same. Especially for the models using Willison couplers, this type of coupler realizes the locking and unlocking of the coupler by the extension and retraction of the hook tongue inside the hook cavity. Except for being able to couple with some CA-3 couplers, this type of coupler can basically not be coupled with other standard couplers. However, there are still many application scenarios for Willison couplers so far. Therefore, it is necessary to improve the existing couplers and design a coupler that can cooperate with Willison couplers. Summary of the Invention
[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a railway freight car coupler device, method and railway freight car that can cooperate with Willison couplers, filling the technical gap in this regard.
[0005] To achieve the above purpose, the present invention is realized through the following technical solutions:
[0006] In a first aspect, an embodiment of the present invention provides a railway freight car coupler device, including a hook head. The hook head is provided with a hook head inner cavity. The hook head is slidably connected through a sliding inner cavity to realize the switching between the state where the hook top extends into the hook head inner cavity and the state where it retracts into the sliding inner cavity. The rear end of the hook top passes through a release shaft through a sliding hole. The release shaft is connected to a hook lifting rod through a connecting component. The front end of the hook top is rotatably connected to a lock core through a rotating shaft. The lock core includes a first core part and a second core part arranged crosswise. An unlocking wheel is fixedly connected to one end of a push iron for cooperating with the first core part. The hook top is provided with a through groove for the first core part to pass through. One side of the hook top is also provided with a latch for cooperating with the second core part. The latch is connected to the hook head;
[0007] The release shaft drives the push iron to rotate. The push iron can contact the first core part and drive the first core part to rotate into the through groove so that when the push iron contacts the hook top, the second core part is disengaged from the cooperation state with the latch. The push iron continues to rotate to drive the hook top to move along the sliding inner cavity.
[0008] Optionally, the connecting component adopts a chain and a connecting block. One end of the chain is connected to one end of the hook lifting rod, and the other end of the chain is connected to the outer edge of the connecting block. The connecting block is fixedly connected to the end of the release shaft.
[0009] Optionally, one end of the hook head is provided with a hook head inner cavity, and the other end is connected to the hook tail frame through a hook tail pin. A front yoke plate and a buffer are arranged inside the hook tail frame, and the front yoke plate is arranged close to the hook head.
[0010] Optionally, one end of the push iron is connected to the unlocking shaft, and the other end is provided with a push head. The thickness of the push head is greater than the width of the through slot so that after the push head pushes the first core part from one side of the through slot to the other side, the push head can contact the hook top.
[0011] Optionally, a protrusion for cooperating with the second core part is provided at the rear end of the latch.
[0012] Optionally, the sliding hole is a kidney-shaped hole with an arc-shaped structure.
[0013] Optionally, the hook head is provided with a connecting column, and the connecting column passes through the connecting hole provided in the latch so that the latch is connected to the hook head.
[0014] Optionally, the connecting hole is a kidney-shaped hole with an arc-shaped structure.
[0015] In a second aspect, an embodiment of the present invention provides a working method for the railway freight car coupler device described in the first aspect.
[0016] In the natural state, the hook top extends into the hook head inner cavity under the action of its own gravity, and the lock core maintains the state of the second core part cooperating with the latch under the action of gravity, and the railway freight car coupler device is in the locked state.
[0017] By rotating the unlocking shaft through the hook lifting rod, the push iron rotates under the action of the unlocking shaft. The end of the push iron first contacts the first core part, drives the lock core to rotate, so that the first core part rotates from one side of the through slot of the hook top to the inside of the through slot. At this time, the push iron contacts the hook top, and the second core part rotates to release the cooperation with the latch. The push iron continues to rotate to drive the hook top to move, so that the hook top moves from the state of extending into the hook head inner cavity to the state of retracting into the sliding inner cavity, thereby releasing the locked state of the railway freight car coupler device.
[0018] In a third aspect, an embodiment of the present invention provides a railway freight car provided with the railway freight car coupler device described in the first aspect.
[0019] The beneficial effects of the present invention are as follows:
[0020] 1. For the railway freight car coupler device of the present invention, through the settings of the lock core, latch, unlocking shaft and push iron, the hook top can be retracted into the sliding inner cavity by using the hook lifting rod, thereby realizing the unlocking of the coupler device, realizing the combination of the existing coupler unlocking method and the willison coupler, meeting the cooperation of the coupler device and the willison coupler, and filling the technical gap in this aspect.
[0021] 2. The coupler device of the railway freight car of the present invention, through the arrangement of the front yoke plate and the buffer, plays a buffering role when the coupler device is impacted in the coupled state, ensuring the stability and safety of the connection state of the coupler device.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0031] Embodiment 1
[0032] This embodiment provides a coupler device for a railway freight car, as Figures 1 - 7As shown in the figure, it includes a hook head 1. The hook head 1 adopts a cuboid structure. One end of the hook head 1 is provided with a hook head inner cavity 2, and the other end edge is provided with a rounded corner structure. The shape of the hook head at the end where the hook head inner cavity is provided matches that of the willison coupler, and the shape of the hook head inner cavity 2 matches the shape of the hook head inner cavity of the willison coupler. The hook head 1 is provided with a sliding inner cavity 3, and a hook top 4 is slidably connected in the sliding inner cavity 3. The hook top 4 can move from a state of being retracted into the sliding inner cavity 3 to a state of partially extending into the hook head inner cavity 2. When a part of the hook top 4 extends into the hook head inner cavity 2, the entire coupler device is in a locked state. When the hook top 4 is completely retracted into the sliding inner cavity, the entire coupler device is in a state of unlocking the lock.
[0033] A hook top 4 and a latch 5 located on one side of the hook top 4 are provided in the sliding inner cavity 3. A connecting column 6 is provided on the cavity surface of the sliding inner cavity 3 away from the hook top 4. The connecting column 6 extends into a connecting hole 7 provided in the latch 5 to limit the translation of the latch 5 in the sliding inner cavity. A limiting protrusion 8 is further provided at the front end of the latch 5. The limiting protrusion 8 is embedded in a limiting groove 9 provided at the front end of the cavity surface of the sliding inner cavity 3. Through the cooperation of the limiting groove 9 and the limiting protrusion 8, the rotation of the latch 5 is avoided, thereby realizing the connection of the latch 5 to the hook head 1 and avoiding the large-scale translation and rotation of the latch 5.
[0034] Preferably, the connecting hole 7 adopts an arc-shaped waist-shaped hole.
[0035] The hook top 4 includes a hook top body. Raised portions are provided at the front end and both side portions of the hook top body. The raised portion at the front end is used to extend into or retract from the sliding inner cavity 3. A through groove 10 is provided in the raised portion on one side. A sliding hole 11 is provided at the rear end of the hook top body. The unlocking shaft 12 vertically passes through the hook top body through the sliding hole 11. The unlocking shaft 12 is rotatably connected to the hook head 1. The unlocking shaft 12 can rotate around its own axis, and the hook head 1 limits the unlocking shaft 12 so that the unlocking shaft 12 can only rotate around its own axis.
[0036] In this embodiment, the sliding hole 11 adopts an arc-shaped waist-shaped hole. The hook top 4 can move through the sliding hole 11, and the movement of the hook top 4 is limited by the unlocking shaft 12.
[0037] In the natural state, the hook top 4 uses its own gravity to make the rear end of the sliding hole 11 contact the unlocking shaft 12. At this time, a part of the hook top 4 extends into the hook head inner cavity 2, and the coupler is in a locked state.
[0038] A rotating shaft 13 is provided on one side of the front end of the hook top 4. The rotating shaft 13 and the through groove 10 are on the same side of the hook top 4. The hook top 4 is rotatably connected to the lock core through the rotating shaft 13. The lock core can rotate around the rotating shaft, and the position of the lock core is between the hook top body and the latch.
[0039] The lock core includes a first core part 14 and a second core part 15 which are arranged crosswise, and one ends of the first core part 14 and the second core part 15 are connected to form a V-shaped structure.
[0040] The lock core is rotatably connected to the rotating shaft 13 at the cross position of the first core part 14 and the second core part 15. In the natural state, under the action of gravity, the first core part 14 is located on one side of the through groove 10, the second core part 15 is located on the other side of the through groove 10, and the first core part 14 is arranged closer to the front end of the hook top 4.
[0041] The thickness of the first core part 14 matches the width of the through groove 10, and the first core part 14 can enter or pass through the through groove 10.
[0042] The unlocking shaft 12 is fixedly connected to one end of the push iron 28. The push iron 28 is arranged at the position between the hook top 4 and the latch 5. One end of the push iron 28 is fixedly connected to the unlocking shaft 12, and the other end is provided with a push head 16. The push head 16 cooperates with the first core part 14 of the lock core. When the unlocking shaft 12 rotates, the push head 16 can contact the first core part 14, so that the push iron 28 drives the whole lock core to rotate around the rotating shaft 13 by means of the push head 16.
[0043] In this embodiment, the thickness of the push head 16 is greater than the width of the through groove 10. After the push head 16 pushes the first core part 14 into the through groove 10, the push head 16 can contact the protrusion provided with the through groove 10 in the hook top 4. When the push head 16 continues to move, the push head 16 can drive the hook top 4 to move, so as to realize the retraction of the hook top 4 into the sliding inner cavity 3.
[0044] A protrusion 17 is provided at the rear end of the latch 5. In the natural state, the protrusion 17 cooperates with the end of the second core part 15. At this time, when the hook top 4 contracts inward, the second core part 15 cooperates with the protrusion 17 to limit the inward contraction of the hook top 4.
[0045] The outer end of the unlocking shaft 12 is connected to the hook lifting rod 18 through a connecting mechanism. The connecting mechanism includes a connecting block 19 and a chain 20. One end of the chain 20 is connected to the hook lifting rod 18 through a hook provided at the end of the hook lifting rod 18, and the other end of the chain 20 is hung and connected to the edge of the connecting block 19. The connecting block 19 is fixed to the outer end of the unlocking shaft 12.
[0046] Pulling the hook lifting rod 18 can pull the connecting block 19 by means of the chain 20, and the connecting block 19 drives the whole unlocking shaft 12 to rotate around its own axis.
[0047] One end of the hook 1 is provided with a hook inner cavity 2, and the other end is connected to one end of the hook tail frame 22 through a hook tail pin 21. In this embodiment, the hook tail pin 21 is a cylindrical pin or an elliptical cylindrical pin, and those skilled in the art can select according to actual needs.
[0048] Inside the coupler yoke 22, a front draft gear 23 and a buffer 24 are installed. The front draft gear 23 is arranged close to the coupler head 1. The buffer 24 can adopt existing equipment, and the fixing method of the front draft gear 23 and the buffer 24 can also adopt existing technology, so no detailed description will be given here.
[0049] When the vehicle is in long formation, the front draft gear 23 and the buffer 24 can buffer the impact when the coupler is in the coupled state, ensuring the stability and safety of the connection state of the coupler device.
[0050] Embodiment 2
[0051] This embodiment provides a working method of the railway freight car coupler device described in Embodiment 1:
[0052] In the natural state, under the action of its own gravity, the front end of the coupler top 4 extends into the coupler head cavity 2. The rear end of the sliding hole 11 contacts the unlocking shaft 12. Under the action of its own gravity, the lock core makes the first core part 14 located on one side of the through slot 10. The second core part 15 cooperates with the protrusion 17 provided on the latch 5. At this time, the entire railway freight car coupler device is in the locked state.
[0053] When the staff pulls the coupler lifting lever 18, the coupler lifting lever 18 drives the unlocking shaft 12 to rotate by using the chain 20 and the connecting block 19. The pushing head 16 of the pusher 28 contacts the first core part 14, driving the lock core to rotate. At this time, the second core part 15 releases the cooperation state with the protrusion 17 of the latch 5. When the first core part 14 rotates into the through slot 10, the pushing head 16 of the pusher 28 contacts the coupler top 4. The pusher 28 continues to rotate, driving the coupler top 4 to slide inward along the sliding inner cavity 3 until the unlocking shaft 12 contacts the front end of the sliding hole 11. At this time, the coupler top 4 retracts into the sliding inner cavity 3, and the entire railway freight car coupler device is in the unlocked state.
[0054] When two railway freight car coupler devices are docked, the coupler devices can produce a certain horizontal shaking, so that the two coupler heads are mutually clamped and locked by the lock tongue, realizing the locking and fixing of the two coupler devices.
[0055] By adopting the coupler device and the working method of this embodiment, through the settings of the lock core, latch, unlocking shaft and pusher, the coupler top can be retracted into the sliding inner cavity by using the coupler lifting lever, thus realizing the unlocking of the coupler device, realizing the combination of the existing coupler unlocking method and the willison coupler, meeting the cooperation of the coupler device and the willison coupler, and making up for the technical blank in this aspect.
