[0021] EMBODIMENTS

[0022] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 1 Fig. 1 shows a perspective view of a casting 1 in the background art, Figure 2 Fig. 2 shows a schematic view of a lifting device in an embodiment, Figure 3 Fig. 3 shows a schematic view of the cooperation between the lifting device and the casting 1 in an embodiment Figure 1 . Figure 4 Fig. 4 shows a schematic view of the cooperation between the lifting device and the casting 1 in an embodiment Figure 2 .

[0023] The device comprises a pin body 10 inserted into the auxiliary groove 2, a connecting part 40 connected to the pin body 10, and a limiting part 20 movably connected to the connecting part 40, wherein the limiting part 20 is connected to the connecting part 40 and has at least a first state and a second state: in the first state, when the pin body 10 is embedded in the auxiliary groove 2 and slides axially to separate from the auxiliary groove 2, the limiting part 20 abuts against the protruding part 3 to limit the axial sliding of the pin body 10; in the second state, when the pin body 10 is embedded in the auxiliary groove 2 and slides axially to separate from the auxiliary groove 2, the limiting part 20 slides axially with the pin body 10 to separate from the auxiliary groove 2.

[0024] As shown in the coordinate axes of the embodiment, the auxiliary groove 2 is a cylindrical groove opened along the Y direction, that is, the Y axis direction is the axial direction, and the shape and length of the pin body 10 are matched with those of the auxiliary groove 2, so that the pin body 10 is inserted into the auxiliary groove 2, and the casting 1 can be lifted by external force to realize the hoisting of the casting 1. Figure 3

[0025] The first state refers to the hoisting state, in which the limiting part 20 abuts against the protruding part 3 when the pin body 10 slides axially, thereby limiting the pin body 10 from separating from the auxiliary groove 2; in the second state, the pin body 10 embedded in the auxiliary groove 2 can slide axially to separate from the auxiliary groove 2, so as to facilitate the installation and disassembly between the casting 1 and the lifting device.
