Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for molten iron pouring, and in particular to a quick locking device for a spheroidizing ladle tilting car. Background Technology

[0002] During the pouring process, the spheroidizing ladle used for molten iron casting needs to be placed on a tilting car. The pouring car tilts, pouring the molten iron into the pouring trough. During the tilting process, the spheroidizing ladle needs to be securely fixed to prevent it from falling off or tipping over.

[0003] After several pours, the high-temperature resistant material inside the spheroidizing ladle may age and detach, requiring replacement. Currently, the spheroidizing ladle is secured with locking bolts and nuts, which are frequently covered by spilled molten iron. This results in a significant time commitment to cleaning molten iron residue before disassembling the ladle, followed by using a wrench to loosen the nuts and replace it with a new ladle. The disassembly and replacement process is time-consuming, labor-intensive, and inefficient, and the prolonged exposure to high temperatures during disassembly negatively impacts personnel health. Furthermore, the disassembly process disrupts production on the assembly line, reducing the overall efficiency of the cast iron production line. Utility Model Content

[0023] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0024] like Figure 1-2 As shown in the figure, the quick locking device for spherical bag tipping cart provided in this utility model embodiment includes: a handle 1, a handle connecting rod 11, a rocker arm 2, a clamping screw 3, a clamping connecting rod 4, and a base 8.

[0025] The handle connecting rod 11 is bent; one end of the handle connecting rod 11 is hinged to the base 8, and the other end is fixedly connected to the handle 1; specifically, a third pin 7 is provided on the base 8; the handle connecting rod 11 is movably connected to the third pin 7, realizing the hinge connection between the handle connecting rod 11 and the base 8. The base 8 is fixed on the tilting vehicle.

[0026] The bent portion of the handle connecting rod 11 is hinged to one end of the rocker arm 2; the other end of the rocker arm 2 is hinged to the clamping connecting rod 4; specifically, the bent portion of the handle connecting rod 11 is hinged to the rocker arm 2 via a fourth pin 9. A first pin 5 is provided on the clamping connecting rod 4, and the rocker arm 2 is movably connected to the first pin 5, thereby achieving the hinge connection between the rocker arm 2 and the clamping connecting rod 4.

[0027] One end of the clamping connecting rod 4 is hinged to the base 8, and the other end is fixedly installed with the clamping screw 3. Specifically, a second pin 6 is provided at the top of one end of the base 8; the clamping connecting rod 4 is movably connected to the second pin 6, so as to realize the hinge connection between the clamping connecting rod 4 and the base 8.

[0028] A limiting pin 10 is provided on the base 8. The limiting pin 10 is specifically located below the second pin 6. A groove is provided on the top of the base 8 to allow for the movement of the rocker arm 2.
