Description

Technical Field

[0001] The present invention belongs to the technical field of railway vehicles, and more specifically, relates to a coupler anti-jump device and a railway vehicle. Background Art

[0002] As an important connecting component of railway vehicles, couplers are subject to huge traction and impact forces when railway vehicles are running at high speeds. The couplers themselves have sufficient strength to ensure that they can withstand external impacts, but the couplers are not completely rigidly connected. The automatic connection or separation between the couplers is achieved through the coupler lock pin mechanism including the hook tongue and the lock iron. During the operation of railway vehicles, abnormal separation between couplers may occur due to factors such as vibration and impact. In particular, with the development of high-speed and heavy-load railway transportation, the probability of coupler separation due to abnormal disengagement of the lock iron during operation has greatly increased. In order to ensure the safe operation of railway vehicles, it is particularly important to prevent abnormal separation of couplers. Summary of the invention

[0003] The purpose of the present invention is to provide a coupler anti-jump device and a railway vehicle, so as to solve the problem that the existing coupler is prone to abnormal separation due to factors such as vibration and impact during the operation of the railway vehicle.

[0033] Specifically, to solve the problem that the existing coupler is prone to abnormal separation due to factors such as vibration and impact during the operation of railway vehicles; the anti-jump device for a coupler provided by the present invention has a pressure column 2, with a lock plate 3 provided at one end of the pressure column 2. The lock plate 3 can rotate with the pressure column 2 and enter the lock groove 5 on the locking guide plate 4. Then, the lock pin 7 inserted into the second through hole 6 can form a limit on one side of the lock plate 3 in the lock groove 5, preventing the lock plate 3 from moving out of the lock groove 5, thereby preventing the pressure column 2 from axially moving. The other end of the pressure column 2 is used to press the locking iron to prevent it from abnormally jumping out, thereby realizing the anti-jump and anti-separation of the coupler.

[0034] Optionally, the outer diameter of the pressure column 2 is matched with the aperture of the first through hole.

[0035] Specifically, it is only necessary that the outer diameter of the first through hole is slightly larger than the outer diameter of the pressure column 2, which ensures the positioning and guiding functions of the seat plate 1 and enables the pressure column 2 to rotate freely.

[0036] Optionally, an annular first limiting portion 8 is provided on the outer periphery of the other end of the pressure column 2, and the outer diameter of the first limiting portion 8 is larger than the aperture of the first through hole.

[0037] Specifically, the setting of the first limiting portion 8 makes it difficult for the pressure column 2 to disengage from the seat plate 1 even when it is not in the working state, avoiding the loss of the pressure column 2.

[0038] Optionally, the locking guide plate 4 is connected to the seat plate 1.

[0039] Specifically, the locking plate 3 guide plate can be welded to the seat plate 1 through a connecting plate to form an integral structure.

[0040] Optionally, the locking plate 3 is a rectangular plate. One end of the locking plate 3 is connected to the end face of one end of the pressure column 2, and the other end of the locking plate 3 extends outward in the radial direction of the pressure column 2 to form an extension portion.

[0041] Specifically, the extension portion can be rotated into the locking groove 5 to achieve locking. After locking, the pressure column 2 cannot move axially.

[0042] Optionally, the locking guide plate 4 is a U-shaped plate, and a locking groove 5 with three open sides is formed inside the U-shaped plate.

[0043] Specifically, the locking plate 3 guide plate can be processed by cutting the locking groove 5 with a rectangular block or by bending.

[0044] Optionally, the outer diameter of the locking pin 7 is matched with the aperture of the second through hole 6.

[0045] Specifically, the aperture of the second through hole 6 is slightly larger than the outer diameter of the locking pin 7, ensuring that the locking pin 7 can be easily inserted into the locking plate 3 guide plate.

[0046] In this embodiment, a third through hole matching the second through hole 6 is provided on the extension portion of the locking plate 3, and the locking pin 7 passes through the second through hole 6 and the third through hole 7 to lock the locking plate 3.

[0047] In another embodiment, after the extension portion of the locking plate 3 enters the locking groove 5, one side of the extension portion contacts the bottom of the locking groove 5, and the other side of the extension portion contacts the outer periphery of the locking pin 7, which can also prevent the locking plate 3 from moving out of the locking groove 5.

[0048] Optionally, an annular second limiting portion 9 is provided on the outer periphery of one end of the locking pin 7, and the outer diameter of the second limiting portion 9 is larger than the aperture of the second through hole 6.

[0049] Specifically, the setting of the second limiting portion 9 makes the locking pin 7 form a structure of a cotter pin, which is convenient to use.

[0050] Optionally, an opening pin hole 10 is provided at the other end of the locking pin 7 for passing through an opening pin.

[0051] Specifically, a split pin can be inserted into the split pin hole 10 to prevent the locking pin 7 from abnormally slipping out.

[0052] In this embodiment, a hook 11 is provided on the upper side of the lock plate 3. The locking pin 7 is connected to the hook 11 through a connecting chain 12, which can prevent the locking pin 7 from being lost.

[0053] In this embodiment, a wing plate 13 is provided on the outer side of the closed end of the locking guide plate 4. A jack 14 is provided on the wing plate 13. The locking pin 7 can be inserted into the jack 14 for placing the locking pin 7.

[0054] The present invention also provides a railway vehicle, including:

[0055] a coupler;

[0056] the above-mentioned coupler anti-hopping device.

[0057] Specifically, the railway vehicle provided by the present invention adopts the above-mentioned coupler anti-hopping device. After the coupler is connected, the locking iron of the coupler is pressed by the pressure column 2, the lock plate 3 and the pressure column 2 are rotated, the extension part of the lock plate 3 is turned into the lock groove 5 of the locking guide plate 4, and then the locking pin 7 is inserted into the second through hole 6 to limit the lock plate 3 placed in the lock groove 5, preventing the lock plate 3 from rotating and moving out of the lock groove 5; through the limit of the lock plate 3 by the guide plate, the limit of the pressure column 2 and the locking iron is realized, preventing the locking iron from abnormally jumping out, and thus realizing the anti-hopping and anti-separation of the coupler. This coupler anti-hopping device can not only effectively prevent hopping and separation, but also has a very simple structure, is very convenient to operate, and has high structural reliability, which is a very important design factor for the coupler anti-hopping device.
