TECHNICAL FIELD
[0001] The utility model belongs to railway transport equipment technical field, concretely is a kind of empty heavy car positive hook device. BACKGROUND
[0002] In railway freight, dumper is widely used to unload bulk cargo, such as coal, ore, etc. However, in the process of dumper overturning unloading door, the Jan car coupler of train often tilts to one side due to gravity and mechanical movement. This phenomenon leads to the difficulty of successful docking of the Jan car couplers of two adjacent cars when the empty crane pushes the car for marshalling or disassembly, resulting in connection failure, which not only affects the operation efficiency, but also may cause damage to the equipment, and even cause safety accidents. Therefore, it is particularly important to design an empty heavy car positive hook device that can effectively correct the tilt state of Jan car coupler and ensure correct connection of car coupler.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0021] Example 1, by Figures 1-6 As shown, this utility model includes a fixing block 1, a connecting shaft 2 passing through the lower part of the fixing block 1, a U-shaped frame 3 rotatably sleeved on the outside of the connecting shaft 2, a guide arm 4 welded to one end of the U-shaped frame 3, a positioning plate 5 connected to the lower end of the U-shaped frame 3, and a waist-shaped hole 6 passing through the side of the positioning plate 5 away from the U-shaped frame 3.
[0022] A connecting block 7 is symmetrically connected to the upper side of the fixed block 1. An ear block 9 is rotatably connected between the two connecting blocks 7 via a pin 8. An upper stop block 10 is fixedly connected to the lower end of the ear block 9. A smooth rod 11 is fixedly connected to the lower end of the upper stop block 10. The lower part of the smooth rod 11 passes through the waist-shaped hole 6. A lower stop block 12 is bolted to the lower end of the smooth rod 11. A spring 13 is sleeved on the outside of the smooth rod 11. The upper end of the spring 13 contacts the upper stop block 10, and the lower end of the spring 13 contacts the positioning plate 5.
[0023] One side of the fixed block 1 is connected to the limiting block 14. When the U-shaped frame 3 is horizontal, it contacts the lower end face of the limiting block 14. The limiting block 14 is used to limit the maximum rotation angle of the U-shaped frame 3 to prevent excessive tilting.
[0024] The guide arm 4 has a guide arc surface 15 at one end edge away from the U-shaped frame 3. The guide arc surface 15 facilitates contact with the contact parts at the bottom of the James coupler and guides its alignment.
[0025] Working principle:
[0026] When in use, the device is installed below the James coupler. When the tipper flips the door, causing the James coupler to tilt, the guide arm 4 of this device first contacts the contact part at the bottom of the James coupler during the process of the empty crane pushing the car. Through the design of the guide arc surface 15, the James coupler is gradually guided back to the center position. At the same time, the elasticity of the spring 13 allows the U-shaped frame 3 and the guide arm 4 to self-adjust and play a certain buffering role, ensuring that the coupler always maintains the correct alignment during the connection process and ensuring the success rate of the connection.
