[0028] In order to describe the present invention in detail, a metallurgical vehicle coupling mechanism 1 and a hook-off device of the present invention are specifically described below:

[0029] Please combine Figures 1 to 5 As shown, the utility model provides a metallurgical vehicle coupling mechanism 1, including a drive shaft 14, on which a drive pin 11 and a sleeve 12 are arranged; a decoupling groove 15 is provided on the sleeve 12, and the drive pin 11 is used to slide in the decoupling groove 15; wherein, the first end of the drive shaft 14 is sleeved in the sleeve 12, and the second end of the drive shaft 14 is used to connect with the power device, and the sleeve 12 has a first force-applying portion 8, and the first force-applying portion 8 is arranged corresponding to the hook-lifting rod 2, and when the sleeve 12 rotates, the first force-applying portion 8 can drive the hook-lifting rod 2 to move. By arranging the drive pin 11 on the drive shaft 14 and the decoupling groove 15 on the sleeve 12, the drive pin 11 can drive the sleeve 12 to rotate through the decoupling groove 15, thereby driving the hook-lifting rod 2 to rotate. At the same time, the hook lifting rod 2 can also be rotated manually. Since the driving pin 11 can slide in the decoupling groove 15, the above-mentioned power will not be delivered to the driving shaft 14 when the hook lifting rod 2 is rotated manually, so that the metallurgical vehicle coupling mechanism 1 can use the power device to rotate the driving pin 11 to perform the hook removal work, and the hook removal work can also be performed manually. The structure of the metallurgical vehicle coupling mechanism 1 is simple and easy to assemble and maintain.

[0030] The sleeve 12 also has a second force-applying portion 9 arranged opposite to the first force-applying portion 8, and the hook-lifting rod 2 is clamped between the first force-applying portion 8 and the second force-applying portion 9. When the sleeve 12 rotates, the second force-applying portion 9 can drive the hook-lifting rod 2 to move. By providing the second force-applying portion 9, it is convenient for the operator to rotate the sleeve 12 while driving the hook-lifting rod 2 to be lowered. The first force-applying portion 8 and the second force-applying portion 9 are movably connected to the hook-lifting rod 2, which can provide space for the hook-lifting rod 2 to adjust itself when it rotates, avoiding jamming during the process of the hook-lifting rod 2 lifting the hook, and improving the smoothness of the movement of the hook-lifting rod 2 during the working process.

[0031] Specifically, a gripping portion 10 for holding is provided between the first force-applying portion 8 and the second force-applying portion 9, and the gripping portion 10 is respectively connected to the first force-applying portion 8 and the second force-applying portion 9 to form a receiving groove, and the receiving groove is used to receive at least part of the hook-lifting rod 2. The provision of the gripping portion 10 can facilitate the worker to perform the gripping operation, and the gripping portion 10 is respectively connected to the first force-applying portion 8 and the second force-applying portion 9, and when the first force-applying portion 8 or the second force-applying portion 9 is applied, the first force-applying portion 8 and the second force-applying portion 9 can share the force, thereby increasing the force strength between the first force-applying portion 8 and the second force-applying portion 9.

[0032] In detail, the cross-sections of the first force-applying part 8, the second force-applying part 9 and the gripping part 10 are U-shaped. The U-shaped cross-section can make the transition from the first force-applying part 8 to the second force-applying part 9 smooth and reduce the stress concentration part between the first force-applying part 8, the gripping part 10 and the second force-applying part 9.

[0033] Among them, the drive shaft 14 is provided with a drive hole for installing the drive pin 11. The drive pin 11 is installed through the drive hole, which has a simple structure and is easy to assemble. In this embodiment, the drive hole and the drive pin 11 are interference fit, the sleeve 12 is provided with a first disassembly hole 16, and the drive shaft 14 is provided with a second disassembly hole corresponding to the drive hole. The second disassembly hole and the drive hole are connected and have the same hole direction. The sleeve 12 has a disassembly position relative to the drive shaft 14. When the sleeve 12 rotates to the disassembly position, the first disassembly hole 16 and the second disassembly hole are connected and have the same hole direction. The drive hole and the drive pin 11 are interference fit, and the drive pin 11 can be removed from the drive shaft 14 through the first disassembly hole 16 and the second disassembly hole. When the drive pin 11 needs to be replaced, only the drive pin 11 can be replaced, reducing the maintenance and replacement cost. In some embodiments, the drive hole and the drive pin 11 can be connected by an adhesive. In other embodiments, the drive pin 11 is welded to the drive shaft 14. The connection method between the driving pin 11 and the driving shaft 14 can be adjusted according to actual usage requirements.

[0034] The decoupling groove 15 is arranged along the circumference of the sleeve 12. The decoupling groove 15 arranged along the circumference of the sleeve 12 can prevent the sleeve 12 from moving along the axial direction of the drive shaft 14 during the rotation process, and prevent the hook rod 2 from getting stuck during the rotation process.

[0035] Among them, a connecting groove 13 is provided on the first end of the driving shaft 14, and the connecting groove 13 is arranged along the axial direction of the driving shaft 14. The power device drives the driving shaft 14 to rotate through the connecting groove 13. The connecting groove 13 has a simple structure and a good transmission effect. In this embodiment, the power device is a reducer 7. The type of the power device can be adjusted according to actual production needs.

[0036] Specifically, a limiting step 17 is provided on the drive shaft 14 along the circumferential direction, and the limiting step 17 limits the drive shaft 14 on the power device. The limiting step 17 can prevent the drive shaft 14 from moving along its axial direction. The limiting step 17 has a simple structure and is easy to manufacture.

[0037] like Figure 5 As shown, the utility model also provides a metallurgical vehicle unhooking device, including the metallurgical vehicle coupling mechanism 1, the hook lifting rod 2 and the connecting hook 3 as described above, the hook lifting rod 2 has a driving part 6, a transmission part 5 and a hook lifting part 4 arranged in sequence, the driving part 6 and the hook lifting part 4 are both perpendicular to the axial direction of the transmission part 5, the hook lifting part 4 is connected to the connecting hook 3 away from the transmission part 5, the driving part 6 is arranged in the accommodating groove of the metallurgical vehicle coupling mechanism 1, and the axis of the transmission part 5 is arranged corresponding to the axis of the driving shaft 14, so that the rotation of the hook lifting rod 2 can be smoother, avoiding jamming during the rotation of the hook lifting rod 2.

[0038] In summary, by arranging the driving pin 11 on the driving shaft 14 and the decoupling groove 15 on the shaft sleeve 12, the driving pin 11 can drive the shaft sleeve 12 to rotate through the decoupling groove 15, thereby driving the hook lifting rod 2 to rotate. At the same time, the hook lifting rod 2 can also be rotated manually. Since the driving pin 11 can slide in the decoupling groove 15, when the hook lifting rod 2 is rotated manually, the above-mentioned power will not be exclusively delivered to the driving shaft 14, so that the metallurgical vehicle coupling mechanism 1 can use the power device to rotate the driving pin 11 to perform the hook removal work, and the hook removal work can also be performed manually. In addition, the structure of the metallurgical vehicle coupling mechanism 1 is simple, and it is easy to assemble and maintain.
