According to the different widths of different types of casting box components 7, the distance between the two rotating groups 26 is adjusted, and under the cooperation of the two fixing mechanisms 6, the hanging mechanism 2 can be applied to casting box components 7 of different models, and through the cooperation of the external crane and the rotating group 26 and the fixing mechanism 6, the casting box component 7 is driven to complete related operations such as flipping and closing, and finally the purpose of making the device applicable to casting box components 7 of different models is achieved, making the application range of the device wider.

[0024] Further explanation: Figure 5 and Figure 6 As shown, the two rotating groups 26 are arranged symmetrically on the left and right, and the two rotating groups 26 both include motor 261.

The hydraulic pump 66 itself is provided with a control switch.

[0029] First, according to different types of casting box components 7, pull the elliptical plate 1 61 and the elliptical plate 2 69 to make the sliding column 68 slide back and forth in the inner cavity of the telescopic groove 62 to a suitable position, and at the same time the square tube 65 slides back and forth in the inner cavity of the sliding groove 4 64, and the oil pipe runs through the inner cavity of the square tube 65 for stretching and contraction. By installing the square tube 65, the oil pipe is prevented from being stuck between the elliptical plate 1 61 and the elliptical plate 2 69, which protects the oil pipe. Then, the elliptical plate 1 61 and the elliptical plate 2 69 in the two fixing mechanisms 6 are sleeved on the casting box component 7 on the same side, and the hydraulic pump 66 is started.

The pipes are fixedly connected to the hydraulic pump 66, the ends of the two rectangular plates 631 located on the front side that are close to each other are fixedly connected to the ends of the two elliptical plates 61 that are away from each other, the ends of the two rectangular plates 631 located on the rear side that are close to each other are fixedly connected to the ends of the two elliptical plates 69 that are away from each other, the ends of the two hydraulic rods 634 located on the front side that are close to each other are fixedly connected to the ends of the two elliptical plates 61 that are away from each other, and the ends of the two hydraulic rods 634 located on the rear side that are close to each other are fixedly connected to the ends of the two elliptical plates 69 that are away from each other.

[0031] It should be noted that the specific installation method of the hydraulic rod 634 and the circuit connection method and control method in the present invention are all conventional designs and are conventional design means of designers.

[0032] In detail, the hydraulic pump 66 is connected to the hydraulic rod 634 through an oil pipe. By starting the hydraulic pump 66, the hydraulic rod 634 can be driven to extend and retract, so that the second clamping plate 635 slides in the inner cavity of the sliding groove three 633, and the second clamping plate 635 and the first clamping plate 632 are clamped to achieve the purpose of fixing the casting box component 7.

[0033] Further explanation, such as Fig. 9 and Fig.10 As shown, the casting box component 7 includes a box body 71, and the left and right ends of the box body 71 are fixedly connected with front and rear symmetrical connecting columns 72, the outer surfaces of the two connecting columns 72 located on the front side are respectively slidably connected with the inner cavities of the two elliptical plates 61, and the outer surfaces of the two connecting columns 72 located on the rear side are respectively slidably connected with the inner cavities of the two elliptical plates 69, and the middle parts of the left and right ends of the box body 71 are fixedly connected with fixing blocks 73, and the middle parts of the upper ends of the two fixing blocks 73 are each provided with a through hole 1 74, and the upper ends of the two fixing blocks 73 are each provided with a through hole 2 75 on the side away from each other, and the inner cavities of the same-side clamp plate 1 632 and the second clamp plate 635 are jointly fitted with the side of the outer surface of the same-side connecting column 72 away from the box body 71.

In addition, when closing the boxes, the upper box needs to be hoisted flat, aligned with the lower box and fastened to complete the closing of the boxes. The closing of the boxes is to adapt and fix the two casting box components 7. That is, during the closing of the boxes, first, the elliptical plate 1 61 and the elliptical plate 2 69 are respectively mounted on the four connecting columns 72, and the connecting columns 72 are clamped by the clamping plate 1 632 and the clamping plate 2 635. After the chain 2691 is mounted on the elliptical plate 1 61 and the elliptical plate 2 69, the upper box, that is, the box body 71 on the upper side, is hoisted under the action of the external crane and the hook 1, so that the upper box is moved directly above the lower box, and the positioning component 2692 is started to make the positioning component 2692 infrared irradiate the through hole 2 75, so that the through hole 2 75 of the upper box is aligned with the through hole 75 of the lower box. Two 75 are aligned. At this time, the alarm in the positioning component 2692 sounds an alarm prompt, indicating that the upper box is aligned with the lower box. Then the upper box is lowered and placed directly above the lower box, and the two through holes 74 are penetrated through the inner cavity of the upper and lower boxes by an external fixed connecting rod, so that the upper and lower box fixing blocks 73 are fixed together, so as to achieve the purpose of closing the upper and lower boxes. It should be noted that no matter how big the box body 71 is, the fixing block 73, the through hole 1 74 and the through hole 2 75 are unchanged, and are used in conjunction with the positioning component 2692 to make the closing of the boxes more convenient and quick. The fixing mechanism 6 is installed, and the elliptical plate 1 61 and the elliptical plate 2 69 in the fixing mechanism 6 are tightly matched with the chain 2691. When the chain 2691 rotates, it will not shake like the chain 2691 is directly mounted on the connecting column 72 for rotation, thereby increasing its flipping stability.
