[0002] The locomotive coupler is a connecting device between locomotives and rolling stock or between locomotives. It is one of the important components of railway trains. The locomotive coupler includes structures such as the coupler head, coupler body and coupler tail, and also includes a buffer structure with a buffer function. When installing the coupler buffer, it needs to be compressed inside the coupler tail before the coupler head and coupler body are installed inside the coupler tail. Currently, existing locomotive couplers usually require manual pressing using compression tools, which is inefficient. Utility Model Content

[0016] Reference Figure 3 The press workbench 1 includes a workbench ramp 10. A ramp groove 11 is opened through the middle of the workbench ramp 10. A coupler support plate 12 is fixedly installed at one end of the workbench ramp 10. A hydraulic rod mounting screw hole 13 is opened inside one end of the coupler support plate 12. A short rod support leg 14 is fixedly installed at one end of the workbench ramp 10, and a long rod support leg 15 is fixedly installed at the other end of the workbench ramp 10. There are two sets of both the short rod support leg 14 and the long rod support leg 15.

[0017] Reference Figure 4 The press-fit hydraulic rod 2 includes a hydraulic rod adapter seat 20. One end of the hydraulic rod adapter seat 20 is rotatably connected to a hydraulic rod adapter sleeve 21. A hydraulic cylinder rod 22 is fixedly inserted through one end of the hydraulic rod adapter sleeve 21. A hydraulic telescopic rod 23 is slidably provided at one end of the hydraulic cylinder rod 22. A hook adapter seat 24 is fixedly provided at one end of the hydraulic telescopic rod 23. A hook adapter shaft 25 is fixedly inserted through one end of the hook adapter seat 24. The hydraulic rod adapter seat 20 has through holes at all four ends that are adapted to the mounting screw holes 13 of the hydraulic rod.

[0018] Reference Figure 5 The press-fit hook 3 includes an arc-shaped hook 30. One end of the arc-shaped hook 30 is fixedly provided with a hook adapter arm 31. One end of the arc-shaped hook 30 is connected to an adjusting screw 32. One end of the adjusting screw 32 is fixedly provided with a rotating hexagonal head 33. There are two sets of hook adapter arms 31. The two sets of hook adapter arms 31 are adapted to and connected with the hook adapter seat 24 and the hook adapter shaft 25.

[0019] Reference Figure 6 The limiting plate 4 includes a T-shaped limiting plate 40. An adjusting internal screw hole 41 is provided through the middle of one end of the T-shaped limiting plate 40. A transfer arm groove 42 is provided through the side of one end of the T-shaped limiting plate 40. The adjusting internal screw hole 41 is adapted to be screwed onto the adjusting screw 32. Two sets of transfer arm grooves 42 are provided. The hook transfer arm 31 is adapted to be inserted into the transfer arm groove 42.

[0020] The above solution is adopted: by opening two sets of adapter arm grooves 42, the limiting plate 4 can be limited to the outer side of the two sets of hook adapter arms 31 at one end of the press hook 3, thereby realizing the adjustment of the limiting plate 4.

[0021] Reference Figure 7 The locomotive coupler 5 includes a coupler tail frame 50. A coupler buffer 51, a coupler follower plate 52, and a locomotive coupler body 53 are installed at one end inside the coupler tail frame 50. The coupler follower plate 52 is located between the coupler buffer 51 and the locomotive coupler body 53. A coupler tail fixing pin 54 is inserted through the coupler tail frame 50 and the locomotive coupler body 53.

[0022] The above scheme is adopted as follows: by flipping the two sets of press-fit hydraulic rods 2, press-fit hooks 3 and limiting plates 4 inward, and adjusting them with the position of the coupler plate 52 by the extension and retraction of the hydraulic cylinder rod 22 and the hydraulic telescopic rod 23, the arc hooks 30 are fastened on both sides of the coupler plate 52. At this time, the arc hooks 30 are stopped after the hydraulic cylinder rod 22 and the hydraulic telescopic rod 23 retract. Then, the limiting plates 4 are adjusted to fit the other side of the coupler plate 52 by rotating the hexagonal head 33 and the adjusting screw 32. Then, the coupler buffer 51 can be compressed by the extension of the hydraulic cylinder rod 22 and the hydraulic telescopic rod 23. In this way, the press-fit assembly of the locomotive coupler can be achieved quickly and conveniently.

[0023] The working principle of this utility model is as follows: First, the two sets of press-fit hydraulic rods 2, press-fit hooks 3, and limit plates 4 are rotated outwards via the hydraulic rod adapter sleeve 21. At this time, the coupler tail frame 50 inside the locomotive coupler 5 is hoisted onto the inclined plate 10 of the workbench and its position is adjusted. Next, the coupler buffer 51 and the coupler follower plate 52 are placed inside the coupler tail frame 50. Then, the two sets of press-fit hydraulic rods 2, press-fit hooks 3, and limit plates 4 are flipped inwards. The hydraulic cylinder rod 22 and hydraulic telescopic rod 23 are used to extend and retract the rods to adapt them to the position of the coupler follower plate 52, so that the arc-shaped hooks 30 are fastened to both sides of the coupler follower plate 52. The arc-shaped hook 30 is brought into contact with the coupler from the plate 52 by the retraction of the hydraulic cylinder rod 22 and the hydraulic telescopic rod 23. At this time, the limit plate 4 is adjusted to contact the coupler from the other side of the plate 52 by rotating the hexagonal head 33 and the adjusting screw 32. Then, the hydraulic cylinder rod 22 and the hydraulic telescopic rod 23 can continue to retract to compress the coupler buffer 51. In this way, the press-fit assembly of the locomotive coupler can be achieved quickly and conveniently. After the coupler buffer 51 is compressed, the locomotive coupler body 53 is inserted into the coupler tail frame 50. Then, the coupler tail fixing pin 54 passes through the coupler tail frame 50 and the locomotive coupler body 53 to complete the press-fit assembly of the coupler.
