Description
Technical Field
[0001] The utility model relates to the technical field of couplers for railway freight cars, in particular to a detachable anti - detachment device for railway freight car couplers. Background Technique
[0002] The coupler is a key component for connecting railway freight car bodies, mainly used on railway freight car models. It is reasonably designed, made of E - grade steel, with high structural strength and good mechanical properties. The coupler is used in combination with the coupler yoke to achieve the rotation function of the coupler, enabling continuous tipping operations without uncoupling the vehicles.
[0003] Ordinary couplers are not closely connected, that is, there is still a certain gap after the coupler is locked. This gap is crucial for the train. Because when the train stops, due to the speed of wind pressure signal transmission, there is a certain time difference in braking between the front and rear vehicles. This time difference causes the rear vehicle to squeeze the front vehicle during braking, making the gap between the couplers empty, resulting in an error in the separation time of the carriages, a difference between the separation position of the carriages and the pre - stop position, and different vehicles may be equipped with different couplers, resulting in differences in coupler height differences, further increasing the impact of coupler height differences on the stop position of the carriages. Content of the Utility Model
[0004] The purpose of the utility model is to provide a detachable anti - detachment device for railway freight car couplers to solve the problem of a certain gap still existing after the coupler is locked as mentioned in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A detachable anti - detachment device for railway freight car couplers, including a coupler head. Fixed blocks are symmetrically arranged at both ends of the coupler head. An arc - shaped fixing frame is fixedly arranged at one end of the fixed block away from the coupler head. A shaft - equipped top block is penetrated through the end of the arc - shaped fixing frame. A return spring is sleeved at one end of the shaft - equipped top block away from the arc - shaped fixing frame. A fixed ring seat is fixedly arranged on one side of the arc - shaped fixing frame close to the coupler head. One end of the coupler head is fixedly connected to a coupler body. A clamping groove is opened at the top of the coupler body. A positioning component is arranged inside the clamping groove. By designing the fixed block, arc - shaped fixing frame, return spring, fixed ring seat and the top block in cooperation with the positioning component, and squeezing the top block by the moving frame in the locking component, the movable distance after the coupler is connected is restricted, further weakening the influence caused by the coupler height difference, and facilitating the reduction of the stop position error of the carriages after the coupler is separated.
[0006] Preferably, the positioning assembly includes a threaded rod, a screwed block, a moving frame, and a locking nut. The threaded rod is installed inside the card slot. The screwed block is threadedly connected to the outer side of the rod body of the threaded rod. The moving frame is fixedly connected to the outer side of the screwed block. A locking nut is fixedly arranged at one end of the threaded rod away from the hook head, which is convenient for restricting the hook difference of the coupler, especially after the connection of couplers of different specifications, within a certain range and restricting the relative displacement between the couplers.
[0007] Preferably, both ends of the threaded rod are connected to both sides of the inner wall of the card slot through pedestal bearings, and the threaded rod rotates relative to the hook head, so that the threaded rod can rotate independently and be screwed with the screwed block.
[0008] Preferably, the screwed block is clamped inside the card slot, and the screwed block moves along the card slot for driving the moving frame to move.
[0009] Preferably, a hook tongue is arranged on one side of the hook head, a hook lock is arranged on one side of the hook tongue, and a hook pin is fixedly arranged on one side of the hook lock to complete the locking after the connection of the coupler and the separation of the coupler.
[0010] Preferably, a hook tail is fixedly arranged at one end of the hook body away from the hook head, and a through hole for fixedly connecting the carriage is opened on one side of the hook tail for connecting the coupler with the carriage.
[0011] Compared with the prior art, the beneficial effects of the present utility model are:
[0012] By designing the fixing block, the arc-shaped fixing frame, the return spring, the fixing ring seat and the top block in cooperation with the positioning assembly, and squeezing the top block by the moving frame in the locking assembly, the movable distance after the connection of the coupler is restricted, further weakening the influence caused by the coupler difference, which is convenient for reducing the stop position error of the carriage after the separation of the coupler.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0019] Please refer to Figures 1-4 , the present invention provides a detachable anti-disconnection device for railway freight car couplers, including a hook head 1. The above-mentioned coupler structure can refer to the structures of No. 13 and No. 16 couplers. Fixed blocks 5 are symmetrically arranged at both ends of the hook head 1. An arc-shaped fixing bracket 6 is fixedly arranged at one end of the fixed block 5 away from the hook head 1. A shafted top block 9 is inserted through the end of the arc-shaped fixing bracket 6. A return spring 7 is sleeved on one end of the shafted top block 9 away from the arc-shaped fixing bracket 6. A fixed ring seat 8 is fixedly arranged on one side of the arc-shaped fixing bracket 6 close to the hook head 1. The return spring 7 is arranged inside the fixed ring seat 8. The fixed ring seat 8 is composed of two ring bodies as a whole. The top of the outer ring body contacts the arc-shaped fixing bracket 6, and the inner ring body is used to block the return spring 7. One end of the hook head 1 is fixedly connected to a hook body 14. A card slot 10 is opened at the top of the hook body 14. A positioning component is arranged inside the card slot 10. The positioning component includes a threaded rod 11, a screwed block 12, a moving frame 13, and a locking nut 15. The threaded rod 11 is installed inside the card slot 10. The outer side of the rod body of the threaded rod 11 is threadedly connected to the screwed block 12. The outer side of the screwed block 12 is fixedly connected to the moving frame 13. A locking nut 15 is fixedly arranged at one end of the threaded rod 11 away from the hook head 1. Both ends of the threaded rod 11 are connected to both sides of the inner wall of the card slot 10 through seat bearings. The threaded rod 11 rotates relative to the hook head 1. The screwed block 12 is clamped inside the card slot 10. The screwed block 12 moves along the card slot 10. A hook tongue 2 is arranged on one side of the hook head 1. A hook lock 3 is arranged on one side of the hook tongue 2. A hook pin 4 is fixedly arranged on one side of the hook lock 3. One end of the hook body 14 away from the hook head 1 is fixedly arranged with a hook tail 16. A through hole for fixedly connecting the carriage is opened on one side of the hook tail 16.
[0020] After the couplers are connected, according to the relationship between the coupler hook difference and the parking position, rotate the locking nut 15. The rotation of the locking nut 15 drives the threaded rod 11 to rotate. The rotation of the threaded rod 11 is screwed with the screwed block 12, so that the screwed block 12 slides along the card slot 10, thereby driving the moving frame 13 to slide, so that the inner wall of the moving frame 13 contacts the shafted top block 9, so that the shafted top block 9 is under pressure and moves closer to each other, restricting the position of the coupler hook tongue 2, so that the hook difference after the couplers are connected is controlled, affecting the time difference during the subsequent separation of the couplers, and further reducing the parking position error.
[0021] When the embodiment of the present application is in use:
[0022] Rotate the locking nut 15. The rotation of the locking nut 15 drives the rotation of the threaded rod 11. The rotation of the threaded rod 11 is screwed with the screwed block 12, so that the screwed block 12 slides along the card slot 10, thereby driving the sliding of the moving frame 13, so that the inner wall of the moving frame 13 contacts the shafted top block 9, so that the shafted top block 9 is subjected to pressure and approaches each other to limit the position of the coupler hook tongue 2.
[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
