Specifically, the ladle car body 1 is provided with an annular groove 12 connected to the through groove 11 around the through groove 11, and the outer ring of the slewing bearing 5 is located in the groove 12, and a fixing ring 13 detachably connected to the ladle car body 1 is provided above the slewing bearing 5. At the same time, the bottom of the ladle support seat 2 is fixedly welded to the inner ring of the slewing bearing 5.

[0034] The utility model of the slewing bearing 5 can continue to refer to the specific setting Figure 1 and Figure 2 ,according to Figure 1 and Figure 2 As can be seen, the outer edge of the fixing ring 13 is fixedly connected to a plurality of fixing plates 14, each of which is provided with a fixing hole. At the same time, an internally threaded hole 15 is provided in the position corresponding to each fixing hole in the ladle car body 1. After the outer ring of the slewing bearing 5 is placed in the groove 12, the fixing ring 13 is placed on top of the outer ring of the slewing bearing 5, and the fixing holes and the internally threaded holes 15 are connected one by one. Then, fixing bolts 16 are screwed into the connected fixing holes and internally threaded holes 15, thereby fixing the fixing ring 13 to the ladle car body 1 via the fixing bolts 16. At this time, the outer ring of the slewing bearing 5 is clamped by the groove 12 and the fixing ring 13, thereby fixing the slewing bearing 5 to the ladle car body 1.

[0035] Continue to refer Figure 1 and Figure 2The ladle car body 1 is located outside the ladle support seat 2 and is equipped with a telescopic mechanism 4 that can move along the direction of the ladle support seat 2. The telescopic mechanism 4 is provided in two groups, and the two groups of telescopic mechanisms 4 correspond one-to-one with the two supporting ears 21 on the ladle support seat 2. Each group of telescopic mechanisms 4 includes multiple vertically arranged spring rods. The tops of all spring rods in the same group of telescopic mechanisms 4 are fixedly connected to the same placement seat 41. The top of the placement seat 41 is provided with a placement groove 42 for placing the ear seat 31. In the utility model, the placement seat 41 is higher than the height of the corresponding supporting ear 21 under the action of the telescopic mechanism 4.

[0036] In order to facilitate the telescopic mechanism 4 to move along the direction of the ladle support seat 2 on the outside of the ladle support seat 2, continue to refer to Figure 1 and Figure 2 The ladle car body 1 is located on the outside of the ladle support seat 2 and is fixedly connected to the track 6 below the telescopic mechanism 4. The bottom end of each group of telescopic mechanisms 4 is connected to the track 6 through a connecting block 61, and the two connecting blocks 61 are connected together by an arc-shaped connecting rod 62.

[0037] In order to facilitate the rotation of the ladle body 3, continue to refer to Figure 1 and Figure 2 A gear ring 22 is fixedly mounted on the outer wall of the ladle support seat 2, and a driving mechanism 17 for driving the gear ring 22 and the ladle support seat 2 to rotate is provided on the ladle car body 1. The driving mechanism 17 specifically includes a reducer located on the ladle car body 1, a driving motor is connected to one side of the reducer, and a driving gear meshing with the gear ring 22 is connected to the top of the reducer.

[0038] The working principle of the rotatable ladle car of this embodiment is as follows: when the utility model is in use, when the lifted ladle body 3 is placed in the through slot 11, the ear seat 31 of the ladle body 3 is first aligned with the placement seat 41 and the supporting ear 21 on the ladle support seat 2, and then the ladle body 3 is lowered. During the lowering process of the ladle body 3, the ear seat 31 of the ladle body 3 first contacts the placement groove 42 of the placement seat 41. As the ladle body 3 continues to move downward, the placement groove 42 is driven to move downward. At this time, the telescopic mechanism 4 is compressed until the placement seat 41 and the supporting ear 21 are at the same height. At this time, the ear seat 31 of the ladle body 3 is simultaneously located on the placement seat 41 and the supporting ear 21, so that the ladle body 3 is jointly supported by the placement seat 41 and the supporting ear 21, preventing the supporting ear 21 from carrying the ladle body 3 alone, which may easily cause damage to the slewing bearing 5.

[0039] When the ladle body 3 needs to be rotated, the driving mechanism 17 can be used to drive the gear ring 22 and the ladle support seat 2 to rotate. The rotating ladle support seat 2 drives the ladle body 3 and the placement seat 41 to rotate simultaneously, thereby achieving the purpose of rotating the ladle body 3.

[0040] Example 2

[0041] refer to Figure 3 and Figure 4 , Example 2 is based on Example 1, and the track 6 of Example 1 is replaced by an annular slide 7 located on the outside of the ladle support seat 2 and below the telescopic mechanism 4. The position corresponding to each group of telescopic mechanisms 4 in the slide 7 is provided with a slider 71 connected to the bottom end of the corresponding telescopic mechanism 4. At the same time, in order to facilitate the sliding of the slider 71, a plurality of self-rolling balls 72 are provided at the bottom of the slide 7, and the two sliders 71 are also connected together by an arc-shaped connecting rod 62.

[0042] When the ladle body 3 needs to be rotated, the rotating ladle support seat 2 drives the ladle body 3 and the placement seat 41 to rotate simultaneously, and the placement seat 41 drives the telescopic mechanism 4 and the corresponding slider 71 to move in the slide groove 7, thereby achieving the purpose of rotating the ladle body 3.

[0043] In the above embodiment, the utility model provides a rotatable ladle car. The placing seat in the utility model is arranged on the ladle car body through a telescopic mechanism. At the same time, since the height of the placing seat is higher than the height of the supporting ear, when the ladle body is placed in the through slot, the ear seat of the ladle body first contacts the placing seat, and then the telescopic mechanism is contracted under the action of the gravity of the ladle body, thereby lowering the height of the placing seat until the height of the placing seat is consistent with that of the supporting ear. At this time, the ladle support seat and the placing seat jointly support the ladle body. Compared with the prior art where the weight of the ladle body is entirely borne by the ladle support seat, the utility model can reduce the load of the ladle support seat, thereby preventing damage to the slewing bearing due to the excessive weight of the ladle body.

[0044] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention.
