Description

Technical Field

[0001] This utility model relates to the field of lifting tool technology, and in particular to a steel billet lifting tool. Background Technology

[0002] The main function of billet lifting equipment is to provide necessary tool support during the transportation, stacking, and lifting of billets. Billet lifting equipment can effectively classify billets according to certain rules, ensuring that the billets are fully utilized.

[0003] In the prior art, a patent document with publication number (CN2466124Y) mentions a lifting device for loading and unloading large-volume steel billets, which includes a support rod with slings symmetrically arranged at both ends of the support rod. The slings are located above the support rod, and hooks are also provided at both ends of the support rod. Two hooks are symmetrically arranged below the support rod. When clamping large-volume steel billets, it is not only safe and reliable, but also saves a lot of steel wire rope and reduces loading and unloading costs.

[0004] However, the aforementioned existing technology, by rotating to position one side of the hook below the billet, makes it difficult to fix the position of the hook when installing larger billets, thus affecting the stability of billet transportation. Utility Model Content

[0020] This utility model provides a billet lifting tool, including a moving rod 1, two sleeves 2, two second screws 16, two third nuts 17, two lifting ropes 3, and two fixing mechanisms. Each fixing mechanism includes a fixing plate 4, two rotating blocks 5, two round rods 6, two connecting ropes 7, a first screw 8, a limiting block 9, a second nut 15, and two fixing structures. The fixing structure includes a connecting plate 11, a support plate 12, a connecting rod 13, a threaded rod 14, and a second nut 15. The aforementioned solution solves the problem in the prior art where, by rotating, one side of the hook is positioned below the billet, making it difficult to fix the position of the hook when installing larger billets, thus affecting the stability of billet transportation.

[0021] In this specific embodiment, two lifting ropes 3 are fixedly connected to the moving rod 1 and located above the moving rod 1. Two fixing mechanisms are respectively disposed at both ends of the moving rod 1. The two ends of the fixing plate 4 are provided with grooves 18. Two round rods 6 are fixedly connected to the fixing plate 4 and located inside the corresponding grooves 18. Two rotating blocks 5 are rotatably connected to the corresponding round rods 6 and are sleeved on the surface of the corresponding round rods 6. Both rotating blocks 5 are provided with openings inside, which are adapted to the round rods 6. The two fixing structures are respectively disposed on one side of the corresponding rotating blocks 5. The two fixing plates 4 are moved to both sides of the workpiece, the rotating blocks 5 are pulled out, the rotating blocks 5 are pulled out of the grooves 18, and the fixing structures are respectively locked on both sides of the workpiece to fix the workpiece. At the same time, the rotating blocks 5 are pushed back into the grooves 18. When the workpiece is pulled up, the rotating blocks 5 are subjected to tension on one side to prevent the rotating blocks 5 from exiting the grooves 18. The installation is simple and the structure is stable.

[0022] One end of each of the two connecting ropes 7 is fixedly connected to the moving rod 1, and the other end of each of the two connecting ropes 7 is fixedly connected to the corresponding rotating block 5. When the workpiece is not fixed, the rotating block 5 extends to the outside of the groove 18, and the connecting rope 7 pulls the rotating block 5. At this time, the outer sides of the two rotating blocks 5 are raised, and the two fixed structures are raised accordingly, which will not hinder the placement of the workpiece.

[0023] Secondly, one end of the first screw 8 is slidably connected to the fixing plate 4, and the other end of the first screw 8 is fixedly connected to the limiting block 9. The limiting block 9 is L-shaped. The first nut 10 is threadedly connected to the first screw 8 and is located on one side of the fixing plate 4. The limiting block 9 is pushed to one side of the workpiece, and the first screw 8 is fixed by the first nut 10. The two limiting blocks 9 are respectively stuck on both sides of the workpiece, which improves stability.

[0024] Secondly, the connecting plate 11 is fixedly connected to the rotating block 5 and located on one side of the rotating block 5. The support plate 12 is disposed below the connecting plate 11. One end of the connecting rod 13 is fixedly connected to the connecting plate 11, and the other end of the connecting rod 13 is slidably connected to the connecting plate 11. One end of the threaded rod 14 is fixedly connected to the connecting rod 13, and the other end of the threaded rod 14 passes through the connecting plate 11 and is threadedly connected to the second nut 15. The support plate 12 is moved below the workpiece. By rotating the second nut 15, the second nut 15 drives the threaded rod 14 to move, so that the support plate 12 contacts the workpiece. The connecting rod 13 is locked inside the connecting plate 11. The cross-section of the connecting rod 13 is square to prevent the connecting rod 13 from rotating.

[0025] In addition, the two sleeves 2 are fixedly connected to the corresponding fixing plates 4 and are located on one side of the fixing plates 4. One end of the two second screws 16 is fixedly connected to the corresponding fixing plates 4, and the other end of the two second screws 16 is slidably connected to the sleeves 2. The two third nuts 17 are respectively threadedly connected to the corresponding second screws 16 and are located on one side of the corresponding sleeves 2. The distance between the two fixing plate 4 assemblies is adjusted according to the shape of the workpiece. By rotating the third nuts 17, the third nuts 17 restrict the position of the second screws 16 and the sleeves 2, thereby fixing the position of the two fixing plates 4.

[0026] When using this utility model, the two fixing plates 4 are moved to the two sides of the workpiece respectively, the rotating block 5 is pulled out, the rotating block 5 is pulled out of the groove 18, the connecting plate 11 is respectively clamped on the two sides of the workpiece to fix the workpiece, and at the same time the rotating block 5 is pushed back into the groove 18. When the workpiece is pulled up, the rotating block 5 is pulled on one side to prevent the rotating block 5 from exiting the groove 18. The first screw 8 is fixed by the first nut 10, the two limiting blocks 9 are respectively clamped on the two sides of the workpiece, and by rotating the second nut 15, the second nut 15 drives the threaded rod 14 to move, so that the support plate 12 contacts the workpiece and fixes the workpiece.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
