Description

Technical Field

[0001] The present invention relates to the technical field of vehicle connection, and in particular to a train coupler and a train having the same. Background Art

[0002] The Jane's coupler is currently the mainstream component used to connect common train cars. It typically consists of a hook body fixed to the car, with a hook tongue hingedly mounted within it. When two cars approach, the hook tongues collide and engage. At this point, a locking iron mounted behind the hook tongue falls under its own weight, locking the tongue. This locked tongue cannot rotate when pulled, maintaining the engaged state.

[0003] However, existing technologies, including the James-style trailer coupler and other types of couplers based on the James-style trailer coupler, suffer from two drawbacks: 1. When the coupler is unlocked, it cannot be immediately locked, requiring a re-entry. 2. The James-style coupler has a complex structure due to its large number of components. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the coupler cannot directly return to the locked state from the unlocked state, which causes the current coupler unlocking process to be inconvenient to operate.

[0005] In order to solve the above technical problems, the present invention provides a train coupler, comprising:

[0006] The hook body is fixedly installed on the carriage;

[0007] A hook tongue is rotatably mounted on the hook body, wherein the hook tongue is adapted to rotate to a mutually engaging state when colliding with another hook tongue;

[0008] A locking iron is rotatably mounted on the hook body, wherein a rotation plane of the locking iron is perpendicular to a rotation plane of the hook tongue, and the locking iron has a first position for blocking the rotation of the hook tongue and a second position for not blocking the rotation of the hook tongue;

[0009] A swing ball is installed in the lock iron, and the lock iron has a ball track suitable for the swing ball to roll therein, and the ball track is located in the rotation plane of the lock iron;

[0010] The swing ball is adapted to be retained in the ball lane at an end away from the hook knuckle when the locking iron is in the second position, and the locking iron is adapted to be retained in the second position when the swing ball is in the ball lane at an end away from the hook knuckle;

[0011] The swing ball is adapted to be kept in the ball lane near one end of the hook tongue when the locking iron is in the first position, and the locking iron is adapted to be kept in the first position when the swing ball is in the ball lane near one end of the hook tongue.

[0012] As a preferred solution, the locking iron has a blocking plate on the upper part of the rotating shaft thereof, and when the locking iron is in the first position, the blocking plate is in a dropped state; when the locking iron is in the second position, the blocking plate is in a raised state.

[0013] As a preferred solution, the ball track is arranged in the blocking plate, and the two ends of the ball track are respectively located on both sides of the rotation axis of the locking iron.

[0014] As a preferred solution, it also includes:

[0015] A first shift lever is rotatably mounted on the hook body;

[0016] The lock iron is provided with a shift head matched with a first shift rod, and the first shift rod is suitable for shifting the shift head and driving the lock iron to rotate from a first position to a second position when rotating.

[0017] As a preferred solution, the hook tongue has an inclined wedge surface on one side close to the shift head, and the inclined wedge surface is suitable for pressing the shift head and driving the locking iron to rotate from the second position to the first position when the hook tongue rotates from the engaged position to the open position.

[0018] As a preferred embodiment, the locking iron also has a third position, which is between the first position and the second position. When the locking iron is in the third position, the swing ball is located in the lane at one end close to the hook tongue, and a fan-shaped plate is provided on the side of the hook tongue close to the locking iron. When the locking iron is in the third position, it relies on its own gravity to rest on the fan-shaped plate.

[0019] As a preferred solution, when the hook tongue is in the engaged position, the locking iron falls from a suspended state to the first position.

[0020] As a preferred solution, it also includes:

[0021] a second lever, rotatably mounted on the hook body;

[0022] The swing arm is fixedly mounted on the rotating shaft of the hook tongue and rotates coaxially with the hook tongue;

[0023] The second shifting rod is adapted to shift the swing rod when rotating, and the swing rod drives the hook tongue to rotate from the engaged position to the open position.

[0024] As a preferred solution, the first shift lever and the second shift lever are fixedly mounted on the same rotating shaft, and a hand wheel is provided at the exposed end of the rotating shaft.

[0025] The present invention also provides a train, comprising a train coupler as described in any one of the above.

[0026] The technical solution of the present invention has the following advantages:

[0027] 1. The present invention provides a train coupler comprising a hook body, a coupler tongue, a locking iron, and a swing ball. The locking iron can be rotated between a first position and a second position to block and unlock the locking iron, thereby locking and unlocking the coupler tongue. The coupler can directly return from an unlocked state to a locked state, resulting in a simple and convenient operation process. Furthermore, the coupler has fewer major components than existing couplers, reducing manufacturing difficulty and cost.

[0028] 2. The present invention provides a train coupler in which the locking iron also has a third position, which can realize three states of the hook tongue, namely locked, unlocked and fully open states, thereby improving the flexibility of the mechanism and the efficiency of disassembly, maintenance and installation.

[0040] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] Example 1

[0042] This embodiment provides a train coupler, such as Figure 1 As shown, it includes: a hook body 1, a hook tongue 2, a locking iron 3 and a swing ball 33; the hook body 1 is fixedly mounted on the carriage; the hook tongue 2 is rotatably mounted on the hook body 1, and the hook tongue 2 is suitable for rotating to a mutual engagement state when colliding with another hook tongue 2; at the same time, the locking iron 3 is also rotatably mounted on the hook body 1, and the rotation plane of the locking iron 3 is perpendicular to the rotation plane of the hook tongue 2, and the locking iron 3 has a first position that blocks the rotation of the locking tongue and a second position that does not block the rotation of the locking tongue; a swing ball 33 is installed in the locking iron 3, and the locking iron 3 has a ball track 34 suitable for the swing ball 33 to roll therein, and the ball track 34 is within the rotation plane of the locking iron 3.

[0043] The swing ball 33 is suitable for remaining in the ball channel 34 at the end away from the hook tongue 2 when the locking iron 3 is in the second position, and the locking iron 3 is suitable for remaining in the second position when the swing ball 33 is in the ball channel 34 at the end away from the hook tongue 2; the swing ball 33 is suitable for remaining in the ball channel 34 at the end close to the hook tongue 2 when the locking iron 3 is in the first position, and the locking iron 3 is suitable for remaining in the first position when the swing ball 33 is in the ball channel 34 at the end close to the locking tongue.

[0044] like Figure 2 As shown, the locking iron 3 has a blocking plate 31 located on its rotation axis. When the locking iron 3 is in the first position, the blocking plate 31 is lowered; when the locking iron 3 is in the second position, the blocking plate 31 is raised. A ball track 34 is located within the blocking plate 31 to limit the movement of the swing ball 33. The two ends of the ball track 34 are located on either side of the rotation axis of the locking iron 3. The ball track 34 is a deep hole set in the locking iron 3, and a blocking wire 35 is threadedly installed at the opening of the deep hole.

[0045] During use, when the hook tongue 2 is in the engaged state, that is, the locking tongue is in the locked state, the locking iron 3 is in the first position, that is, it falls downward, and the entire blocking plate 31 blocks the front end of the hook tongue 2. At this time, the swing ball 33 is in the ball channel 34 close to one end of the locking tongue.

[0046] In order to open the lock tongue, a first lever 4 is rotatably mounted on the hook body 1, and a dial head 32 cooperating with the first lever 4 is provided on the lock iron 3; when the first lever 4 rotates, the dial head 32 can drive the lock iron 3 to rotate from the first position to the second position.

[0047] In the second position, the lock tongue is still in the engaged position, but the gap formed between the blocking plate 31 and the dial head 32 allows the lock tongue to rotate and no longer blocks the rotation of the lock tongue; at this time, the swing ball 33 is at the end of the ball track 34 away from the lock tongue.

[0048] like Figure 3 、 4 As shown, a beveled surface 21 is provided on the side of the hook tongue 2 close to the shift head 32. The setting of the beveled surface 21 can press the shift head 32 and drive the locking iron 3 to rotate from the second position to the first position when the hook tongue 2 rotates from the engaged position to the open position.

[0049] During the rotation of the locking iron 3, there is a third position between the first position and the second position; a fan-shaped plate 22 is provided on the side of the hook tongue 2 close to the locking iron 3; when the locking iron 3 is in the third position, the swing ball 33 is located in the ball channel 34 at one end close to the locking tongue, so the locking iron 3 can rely on its own gravity to rest on the fan-shaped plate 22.

[0050] When the hook tongue 2 rotates from the open position to the engaged position, the locking iron 3 slides off the sector plate 22 and falls to the first position under the action of its own gravity.

[0051] In order to realize the rotation of the hook tongue 2 from the open position to the engaged position, a second shifting rod 5 is rotatably mounted on the hook body 1; at the same time, a rocker rod 7 is fixedly mounted on the rotating shaft of the hook tongue 2, and the rocker rod 7 can rotate coaxially with the hook tongue 2; when the second shifting rod 5 rotates, the rocker rod 7 is shifted, and the rocker rod 7 drives the hook tongue 2 to rotate from the engaged position to the open position.

[0052] like Figure 5 As shown, the first shift lever 4 and the second shift lever 5 are fixedly mounted on the same rotating shaft, and a hand wheel 6 is provided at the exposed end of the rotating shaft.

[0053] Example 2

[0054] This embodiment provides a train, including a train coupler in Example 1.

[0055] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
