[0002] Strip steel is a narrow, long steel plate produced by various rolling mills to meet the needs of industrialized production of various metal or mechanical products across various industries. Strip steel, also known as steel belt, varies slightly in length depending on the size of each coil. After production, strip steel requires hoisting and loading onto trucks. To address this need, we offer a hoisting device for strip steel production.

[0003] Existing lifting devices for strip steel production require the simultaneous cooperation of multiple people, and require a lot of manpower to operate or fix the strip steel, which is time-consuming and labor-intensive. Since the strip steel is usually packaged in discs, the strip steel is easily shaken by external forces during the lifting process, which can easily cause worker injuries and result in low safety.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: Figure 1-5 As shown, the utility model provides a lifting device for strip steel production, including a lifting device body 1, which is suitable for use in strip steel production lifting. The lifting device body 1 includes a connecting top plate 2, a lifting rope 3 is fixedly installed on the top of the connecting top plate 2, a supporting column 4 is fixedly installed on the bottom of the connecting top plate 2, positioning units are provided on both sides of the bottom end of the connecting top plate 2, and a supporting unit is provided on the outer surface of the bottom end of the supporting column 4. The positioning unit includes an inner cavity 21 opened at the bottom of the connecting top plate 2, and the inner cavity 21 has two inner cavities on both sides. A limiting cross bar 22 is fixedly installed at the rear end of the wall, and a bidirectional motor 23 is fixedly installed at the middle position of the internal front end of the inner cavity 21. Threaded rods 24 are fixedly installed on the output ends of both sides of the bidirectional motor 23. The other ends of the threaded rods 24 are rotatably installed at the front ends of the inner walls on both sides of the inner cavity 21. Moving blocks 25 are movably sleeved on the outer surfaces of the threaded rods 24 and the limiting cross bar 22. A resistance ring plate 26 is fixedly installed on the bottom end of the moving block 25, and a fixed block 27 is fixedly installed at the middle position of the bottom of the resistance ring plate 26.

[0025] Furthermore, by inserting the supporting column 4 at the bottom end of the device into the internal through-hole of the strip steel coil, and then driving the threaded rods 24 on both sides to rotate synchronously through the output ends of the bidirectional motor 23 on both sides, the moving blocks 25 on both sides drive the resistance ring plates 26 on both sides to move in opposite directions, and the resistance ring plates 26 are squeezed on the inner wall of the through-hole of the strip steel coil to limit its position and prevent shaking.

[0026] Example 2: Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the supporting unit includes a limiting slide groove 41 opened on the bottom end of the supporting column 4, the outer surface of the supporting column 4 is located above the limiting slide groove 41 and is fixedly sleeved with a fixed ring 42, the internal sliding installation of the limiting slide groove 41 is provided with a movable ring 43, the fixed ring 42, and the movable ring 43 are fixedly installed with a rotating shaft 44 on the outer surface thereof, the rotating shaft 44 is rotatably connected to a rotating support plate 45 at the inner axis thereof, and the other end of the rotating support plate 45 is rotatably connected to a rotating plate 46, and steel cable pull ropes 47 are fixedly installed on both sides of the top of the movable ring 43, and the other end of the steel cable pull rope 47 passes through the fixed ring 42 and extends inside the inner side of the fixed block 27.

[0027] Furthermore, when the two side contact ring plates 26 move in opposite directions, it is convenient to pull the steel cable rope 47 upward.

At the same time, when the resistance ring plates 26 on both sides move in the opposite directions, it is convenient to pull the steel cable rope 47 upward. The upward movement of the steel cable rope 47 drives the moving ring 43 to slide inside the limiting slide groove 41 and move upward. The two sets of rotating support plates 45 rotate and change their own positions until the moving ring 43 is attached to the bottom of the fixed ring 42. At this time, the rotating support plates 45 are supported on the bottom end of the steel coil in a parallel state to carry it.
