Abstract
Description
Technical Field
[0001] The utility model relates to the field of continuous casting sector segments, in particular to a lossless turning device for sector segments. Background Art
[0002] The individual continuous casting machines that make up a continuous casting line are generally referred to as fan-shaped segments. The structural characteristics of these continuous casting machines are that the roller adjustment devices, guides, and other individual components are arranged along a quarter-circle arc and its horizontal extension. During the casting process, the strands are first cast into an arc and then gradually straightened. This structural feature significantly reduces the height of the casting machine.
[0003] The fan-shaped segment includes a frame, in which rollers, adjustment devices, and guide devices are assembled. Hydraulic cylinders, hydraulic pipes, water pipes and other components are also installed on and around the frame.
[0004] To facilitate measurement, maintenance, and adjustment, the fan segment needs to be flipped over. Traditional flipping devices use a crane and slings, supplemented by manual labor, to flip the fan segment. Connecting rings for the slings are provided on both sides of the fan segment frame along its width. One end of the sling is fixed to the connecting ring, and the other end is fixed to the crane hook. Two cranes are used to flip the fan segment, with one crane's hook raising and the other crane's hook lowering to achieve the fan segment's flipping. A flip axis is provided in the middle of each end of the fan segment's length, and a support frame is provided below the flip axis. When the fan segment flips, the support frame supports the flip axis, and workers assist in the smooth flipping of the fan segment by standing next to the fan segment.
[0005] Regarding the aforementioned related technologies, the hook-and-sling system used during the sector flipping process can easily lead to an unstable flipping of the entire sector, which can easily cause the flipping operation to become uncontrolled. This can cause the support frame to topple, the flip axis to lose support, and the entire sector to lose support, leaving the sector dangling in mid-air, posing a significant threat to the safety of workers and on-site equipment. Furthermore, the slings used with the crane during the flipping process can also crush the sector. Utility Model Content

[0034] The following is combined with Figure 1-4 This application is described in further detail.
[0035] The embodiment of the present application discloses a lossless flipping device for a sector.
[0036] Reference Figure 1-4 The non-destructive flipping device for the fan segment includes a support plate 2, a support frame 3, and a lifting assembly 6. The support plate 2 is a reinforced concrete part, and the support frame 3 is fixed to the support plate 2 through a fixing assembly 4.
[0037] The fixing assembly 4 includes a fixing plate 41 and a fixing bolt 42. The fixing plate 41 is fixedly connected to both sides of the support frame 3. One fixing plate 41 corresponds to one fixing bolt 42. The fixing bolt 42 passes through the fixing plate 41 and is threadedly connected to the support plate 2.
[0038] Since the support plate 2 made of reinforced concrete is heavy, the support frame 3 is fixed to the support plate 2 via the fixing assembly 4 , so the support frame 3 is not prone to tipping over.
[0039] A flip shaft 11 is provided in the middle of each end of the sector frame 1 in the longitudinal direction, a receiving groove 321 for placing the flip shaft 11 is provided at the top of the support frame 3, a limiting component 5 is provided at the top of the support frame 3, and the flip shaft 11 is provided between the support frame 3 and the limiting component 5.
[0040] The limiting assembly 5 includes a limiting arc plate 51, a limiting screw 52 and a limiting nut 53. The curvature of the limiting arc plate 51 is adapted to the outer circumferential surface of the flip shaft 11. Mounting plates 521 extend radially on both sides of the limiting arc plate 51. The limiting screw 52 is fixedly connected to the top surface of the support frame 3. The limiting screw 52 corresponds to the mounting plate 521 one by one. The limiting screw 52 passes through the corresponding mounting plate 521. The limiting nut 53 is threadedly connected to the limiting screw 52. The limiting nut 53 is located on the side of the mounting plate 521 away from the support frame 3. A gap is provided between the inner wall of the limiting arc plate 51 and the outer wall of the flip shaft 11, so that the flip shaft 11 can rotate flexibly.
[0041] The flip shaft 11 is not easy to separate from the support frame 3 under the action of the limiting arc plate 51. The limiting arc plate 51 and the support frame 3 cooperate to limit the rotation of the flip shaft 11, thereby improving the stability of the flip shaft 11 during rotation, thereby improving the stability and safety of the overall flipping of the sector segment.
[0042] The support frame 3 includes a fixed base 31 and a movable block 32. The top surface of the fixed base 31 is provided with a lifting slot 311 for the movable block 32 to be raised and lowered.

The waist-shaped hole 312 is vertically arranged and extends through both sides of the base in the thickness direction. A receiving slot 321 is provided on the top surface of the movable block 32.
[0043] A locking screw 323 is provided on each side of the movable block 32 in the thickness direction. The locking screw 323 passes through the waist-shaped hole 312 and is threadedly connected to a locking nut 324, which abuts the outer wall of the fixed base 31. Scale lines 3121 are provided on both sides of the fixed base 31 in the thickness direction. These scale lines 3121 are located at the waist-shaped hole 312, making it easier for personnel to raise and lower the two movable blocks 32 at both ends of the sector to the same height.
[0044] The movable block 32 of the support frame 3 can be adjusted to a suitable height according to the sectors of different sizes, and the heights of the two support frames 3 can be ensured to be consistent with the help of the scale line 3121, thereby ensuring the stability of the sector flipping process.
[0045] A support spring 313 is provided in the lifting groove 311, one end of the support spring 313 abuts against the inner bottom wall of the lifting groove 311, and the other end of the support spring 313 abuts against the bottom surface of the movable block 32. The support spring 313 enables the movable block 32 to support the fan-shaped segment, thereby improving the supporting force of the movable block 32.
[0046] The lifting assembly 6 is used to lift the sector and includes a crane 1 61 , a sling 1 62 , a crane 2 63 , and a sling 2 64 .
[0047] Two connecting lugs 12 are provided on one side of the width of the segment frame 1, located near each end of the lengthwise direction of the segment frame 1. Two connecting lugs 13 are provided on the other side of the width of the segment frame 1, located near each end of the lengthwise direction of the segment frame 1. Each connecting lug 12 corresponds to one sling 62. One end of each sling 62 is connected to the connecting lug 12, and the other end of each sling 62 is connected to the hook of a crane 61. Both slings 62 are connected to the hook of the same crane 61.
[0048] One connecting ear plate 13 corresponds to one sling 64 2. Each sling 64 2 includes a unit belt body 1 641 and a unit belt body 2 642. An auxiliary shaft 7 is provided between the unit belt body 1 641 and the unit belt body 2 642. The auxiliary shaft 7 is provided on the side in the descending direction during the flipping process of the sector segment.
[0049] Two docking lug plates 71 are provided on one radial side of the auxiliary shaft 7. The two docking lug plates 71 are respectively located near the two ends of the auxiliary shaft 7. Two docking lug plates 72 are provided on the other radial side of the auxiliary shaft 7. The two docking lug plates 72 are respectively located near the two ends of the auxiliary shaft 7. The docking lug plate 71 is located directly below the docking lug plate 72. One end of each unit belt body 1 641 is connected to the connecting lug plate 2 13. The other end of each unit belt body 1 641 is connected to the docking lug plate 1 71. One end of each unit belt body 2 642 is connected to the docking lug plate 2 72. The other end of each unit belt body 2 642 is connected to the hook of the crane 2 63. Both unit belt bodies 2 642 are simultaneously connected to the hook of the same crane 2 63.
[0050] Since the auxiliary shaft 7 is arranged on the side in the descending direction during the flipping process of the sector segment, the auxiliary shaft 7 divides the sling 2 64 into the unit belt body 1 641 and the unit belt body 2 642, so that the individual lengths of the unit belt body 1 641 and the unit belt body 2 642 are relatively short. Therefore, during the flipping process of the sector segment, the unit belt body 1 641 on the side in the descending direction is less likely to crush the sector segment due to its shorter length and lighter weight, thereby reducing the possibility of damaging the sector segment.

The connecting nut 83 is threadedly connected to the two ends of the connecting screw 82, and the side of the connecting nut 83 that is close to each other abuts against the side of the vertical section of the connecting plate 81 that is far away from each other.
[0053] The connecting component 29 includes a connecting plate 291, a connecting screw 292, and a connecting nut 293. The connecting plate 291 is U-shaped, and the docking ear plate 1 71 or the docking ear plate 2 72 is clamped between the two vertical sections of the corresponding connecting plate 2 91. The docking ear plate 1 71 and the docking ear plate 2 72 are both provided with a first docking hole 73 for the connecting screw 2 92 to pass through.
