Description

Technical Field

[0001] This utility model belongs to the field of steel structure processing technology, specifically relating to a turning device for steel components. Background Technology

[0002] Steel components are generally assembled horizontally during the manufacturing process, and the working surface is usually the top surface, or the top surface and the side surface. For bottom surface work, it is necessary to turn them over. Turning over occurs not only in the assembly stage, but also in the forming stage and the painting stage. Therefore, this is an unavoidable operation process.

[0003] For H-beams, which have open sections, hooks can be used to clamp the flanges to achieve side flipping. For box-shaped steel components, which have closed sections, the typical flipping process uses an L-shaped steel mechanism to hook the side of the bottom surface of the box-shaped steel component. By using a lifting steel cable, the box-shaped steel component rotates around one side of the bottom surface as a rotation support. Because it is under unilateral force, when the rotation angle of the box-shaped steel component exceeds 45 degrees, the box-shaped steel component will automatically rotate and fall under the action of its own weight overturning moment, which will generate a huge impact on the ground.

[0004] How to control the rotation process of box-shaped steel components is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0038] like Figures 1 to 13 As shown, this utility model discloses a turning device for steel components, which turns over box-shaped steel components. Specifically, the box-shaped steel components of this utility model are steel box beams.

[0039] Example 1,

[0040] A turning device for steel components includes a crane 1 and a connecting assembly 5. The crane 1 can move left and right, and the crane 1 is equipped with a hook 2, which is connected to a wire rope 3. Existing technology controls the raising or lowering of the hook 2 through a power drive unit, typically consisting of a motor and a winding device, as seen in the invention patent entitled "A Simple Turning Method for Large Cylindrical Forgings" (Authorization Announcement No.: CN110523906B). The structure of the crane 1 and the hook 2 will not be described further in this utility model.

[0041] The purpose of this utility model is to set a connecting component 5 at two parallel connecting surfaces 41 of the steel component 4, and the buckle of the wire rope 3 is connected to the connecting component 5. By raising or lowering the wire rope 3, the steel component 4 can rotate around the edge of the steel component 4. Then, by replacing the wire rope 3 with different connecting components 5, the steel component 4 can rotate around different edges, thus turning the steel component 4 over.

[0042] The connecting component 5 in Embodiment 1 includes a sleeve 51 and a connecting rod. The connecting rod includes an integrally formed connecting portion 52 and an end 54, with the cross-sectional area of ​​the end 54 being larger than that of the connecting portion 52. The sleeve 51 is welded to the connecting surface 41 and has a threaded hole 53. The connecting portion 52 is threaded into the threaded hole 53, thus fixing the connecting rod to the sleeve 51. One end of the wire rope 3 is attached to the hook 2, and the other end of the wire rope 3 is attached to the connecting portion 52. The end 54 prevents the wire rope 3 from detaching from the connecting portion 52. This connecting component 5 has a simple structure, allows for quick installation on the connecting surface 41, and improves turning efficiency.

[0043] The turning operation in Embodiment 1 is as follows: Connect the buckle of the wire rope 3 to the connecting part 52 of one of the connecting components 5, then control the hook 2 to rise while simultaneously controlling the crane 1 to move to the right. At this time, the wire rope 3 moves to the right, using one edge of the bottom surface of the steel component 4 as a support edge. The steel component 4 rotates around this support edge. During this process, the rotation angle of the steel component 4 is controlled between 0 and 45 degrees. Figure 4 As shown. Control the crane 1 to move continuously to the right, and control the hook 2 to gradually descend. The steel component 4 continues to rotate around the supporting edge. During this process, the rotation angle of the steel component 4 is controlled between 45 and 90 degrees. At this time, the end 54 of the connecting rod is supported on the ground. To keep the steel component 4 horizontal, wooden blocks a can be placed between the steel component 4 and the ground. Figure 5As shown, the steel component is flipped 90 degrees, and then the buckle of the wire rope 3 is removed from the connecting part 52 of the connecting component 5.

[0044] Control the crane 1 to move to the left. At the same time, control the wire rope 3 to move to the left. Then connect the buckle of the wire rope 3 to the connecting part 52 of another connecting component 5. Then remove the wooden block a. Then control the hook 2 to rise. At the same time, control the crane 1 to move to the right. At this time, the wire rope 3 moves to the right. With one of the edges of the top surface of the steel box girder as the support edge, the steel component 4 rotates around the support edge. Figure 6 As shown. The crane 1 is controlled to move continuously to the right, and the operator manually supports the top surface of the steel component 4 on the ground, as shown. Figure 7 As shown, the steel component is flipped 180 degrees.

[0045] The 90-degree flipping of steel components is mainly used in the painting stage of steel component 4; while the 180-degree flipping of steel components is mainly used in the assembly and welding stage of steel component 4.

[0046] Example 2,

[0047] In Embodiment 1, in order to ensure a firm connection between the connecting part 52 and the sleeve 51, it is necessary to ensure that the connecting part 52 extends into the sleeve 51 by a sufficient length. This will cause the following problems: the length of the connecting part 52 extending out of the sleeve 51 is insufficient, making it difficult for the buckle of the wire rope 3 to be connected to the connecting part 52; the end 54 of the connecting rod needs to be supported on the ground, and the contact area between the end 54 and the ground is small, resulting in the steel component 4 being unstable on the ground after being turned over.

[0048] To address the aforementioned technical problems, this utility model designs another connecting component 5.

[0049] A turning device for steel components includes a crane 1 and a connecting assembly 5. The crane 1 can move left and right. The crane 1 is equipped with a hook 2, and the hook 2 is connected to a wire rope 3. In the prior art, the hook 2 is raised or lowered by a power drive unit, which is generally composed of a motor and a winding device, such as the invention patent entitled "A Simple Turning Method for Large Cylindrical Forgings" (authorization announcement number: CN110523906B). The structure of the crane 1 and the hook 2 will not be described in this utility model.

[0050] The purpose of this invention is to set a connecting component 5 at two parallel connecting surfaces 41 of the steel component 4, and to connect the connecting component 5 with a steel wire rope 3. By raising or lowering the steel wire rope 3, the steel component 4 can rotate around its edge. By changing the steel wire rope 3 to different connecting components 5, the steel component 4 can rotate around different edges, thus turning the steel component 4 over.

[0051] The connecting component 5 in Embodiment 2 includes a connecting seat 55, a support plate 56, and a lifting rod 57. The cable knot of the wire rope 3 is connected to the lifting rod 57. A bolt rod 58 is welded to the connecting surface 41. The connecting seat 55 has a mounting hole 518, through which the bolt rod 58 passes. A nut 59 is threaded onto the bolt rod 58, thus fixing the connecting seat 55 to the connecting surface 41. After the overturning is completed, the entire connecting seat 55 can be disassembled, and the bolt rod 58 can be cut. The bolt rod 58 has a small diameter, resulting in minimal damage to the steel component 4 structure.

[0052] Two symmetrically arranged connecting plates 510 are welded to the support plate 56. The connecting seat 55 has a connecting groove 515, in which a connecting pipe 516 is welded. The connecting pipe 516 has a connecting hole 517. A fixed pipe 511 of a predetermined length passes vertically through the connecting hole 517. The fixed pipe 511 and the connecting pipe 516 are welded and fixed, so that the fixed pipe 511 is fixedly connected to the connecting seat 55. The fixed pipe 511 and the connecting seat 55 have good connection strength to meet the requirements of subsequent installation of fixing bolts. The fixed pipe 511 has a second threaded hole 519. The fixed pipe 511 is supported between the two connecting plates 510. The connecting plate 510 has a third threaded hole 520. The third threaded hole 520 and the second threaded hole 519 are threaded together with fixing bolts 512, so that the support plate 56 is fixed on the connecting seat 55. The support plate 56 is parallel to the connecting surface 41.

[0053] The connecting plate 510 has a through hole 521, and the rod 57 has a threaded part 513. The threaded part 513 passes through the through hole 521, and each threaded part 513 is threadedly connected to two nuts 514. The connecting plate 510 is located between the two nuts 514. By tightening or loosening the nuts 514, the threaded part 513 can move in the through hole 521 to adjust the distance between the threaded part 513 and the connecting surface 41. This allows the rod 57 to be movably connected to the support plate 56, enabling adjustment of the distance between the rod 57 and the connecting surface 41, and providing sufficient installation space for the cable ties of the wire rope 3. At the same time, the rod 57 has sufficient length to connect with the connecting plate 510, providing good connection strength, allowing the connecting assembly 5 of Embodiment 2 to flip over heavy steel components 4. The rod 57 is detachably connected to the connecting plate 510, facilitating timely replacement of the rod 57 and ensuring proper installation of the cable ties of the wire rope 3. Moreover, the support plate 56 has a certain area. The support plate 56 is supported on the ground. Compared with the end 54 in embodiment 1, which is in contact with the ground, the contact area can be increased, thereby increasing the stability of the steel component 4 on the ground after it is turned over.

[0054] The turning operation in Example 2 is as follows: Connect the buckle of the wire rope 3 to the boom 57 of one of the connecting components 5, then control the hook 2 to rise while simultaneously controlling the crane 1 to move to the right. At this time, the wire rope 3 moves to the right, using one side of the bottom surface of the steel component 4 as a support edge. The steel component 4 rotates around this support edge, and the rotation angle of the steel component 4 is controlled between 0 and 45 degrees. Control the crane 1 to continue moving to the right and control the hook 2 to gradually descend. The steel component 4 continues to rotate around the support edge, and the rotation angle of the steel component 4 is controlled between 45 and 90 degrees. At this time, the support plate 56 supports the ground, completing a 90-degree turn of the steel component. Then, remove the buckle of the wire rope 3 from the boom 57 of the connecting component 5.

[0055] The crane 1 is moved to the left, at the same time the wire rope 3 is moved to the left, and the buckle of the wire rope 3 is connected to the boom 57 of another connecting component 5. Then the hook 2 is raised, and the crane 1 is moved to the right, at the same time the wire rope 3 is moved to the right, using one of the top edges of the steel box girder as a support edge, and the steel component 4 rotates around this support edge. The crane 1 continues to move to the right, and the operator holds the steel component 4, supporting the top surface of the steel component 4 on the ground, completing the 180-degree flip of the steel component.

[0056] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
