After being processed in the steel mill, the slab needs to be transported to the rolling mill for further processing. After being processed in the steel mill, the slab will be transported from the roller table of the steel mill to the roller table of the rolling mill. Therefore, a transfer device is required to transfer the slab from the roller table of the steel mill to the roller table of the rolling mill. At present, the transfer of slabs is mainly completed by a slab lifting tool to lift and displace the slab, so as to facilitate the transfer of the slab in the plate workshop of the rolling mill;

[0003] At present, the slabs produced by rolling mills and steel mills involve various length specifications. Before hoisting, the existing hoisting device needs to limit and clamp the slab through a fixture to ensure that the slab can be hoisted stably. However, the current clamping device cannot be adaptively adjusted according to the shape and size of the slab, so that the clamping device cannot effectively adjust and clamp the slab, resulting in the phenomenon that the slab is prone to loosen and fall during subsequent hoisting.

[0028] Limit plates 5 are fixedly connected to one side of the bottom of the hoisting top plate 1 and the bottom of the end plate 3 respectively. The limit plates 5 correspond to the positions of the hoisting seats 4. Sliding grooves 6 are symmetrically opened inside both sides of the limit plates 5, and limit guide grooves 7 communicating with the sliding grooves 6 are penetrated through both side edges of the limit plates 5. Sliding seats 8 are embedded and slidably connected to the inner sides of the two sliding grooves 6. Limit guide blocks 9 are connected to the corresponding limit guide grooves 7 at both side edges of the sliding seats 8;

[0029] Clamping arms 10 are fixedly connected to the bottoms of the two sliding seats 8. The sliding seats 8 are connected with the limit guide grooves 7 through the limit guide blocks 9 at both side ends thereof for limit-guided sliding connection. And a limiting block is arranged at the end of the limit guide block 9 to facilitate the limit-guided sliding of the top of the clamping arm 10 and to facilitate the adjustment of the distance between the two clamping arms 10. And a driving seat 11 is arranged at the bottom of the clamping arm 10. A bidirectional driving screw rod 12 is connected between the two driving seats 11 at the bottoms of the two clamping arms 10 by means of a threaded connection. A turntable 13 is fixedly connected to one end of the bidirectional driving screw rod 12. Clamping seats 14 are fixedly connected to the bottoms of the two driving seats 11. Threads with opposite helix directions are arranged on both sides of the bidirectional driving screw rod 12. The two driving seats 11 are respectively located on the threaded sections in opposite directions of the bidirectional driving screw rod 12. And a nut seat is arranged at the corresponding position of the inside of the driving seat 11 and the bidirectional driving screw rod 12 to facilitate driving the two clamping arms 10, the driving seats 11 and the clamping seats 14 to move towards each other and away from each other in an active driving manner. And limiting grooves 15 are respectively opened at the opposite side edges of the ends of the clamping seats 14. The clamping arms 10 and the clamping seats 14 are both arc-shaped sections, and the clamping arms 10 and the clamping seats 14 form an arc structure. A plane is arranged at the opposite side of the clamping seat 14, and the limiting grooves 15 are arranged on this plane, so that the clamping seat 14 can effectively clamp the edge of the slab, and the limiting grooves 15 inside the clamping seat 14 make the slab have higher clamping stability during the clamping process.

[0030] The sliding structure includes an adjusting sliding groove 16. The adjusting sliding groove 16 is opened inside the bottom of the hoisting top plate 1. A sliding bottom plate 17 is connected to the bottom of the adjusting plate 2. The sliding bottom plate 17 is slidably fitted inside the adjusting sliding groove 16;

[0032] The working principle and usage process of the present utility model: In the actual application process of this adjustable slab clamping device, first, the length of the hoisting top plate 1 is adjusted according to the length of the slab to be clamped and transported, so as to adjust the distance between the hoisting top plate 1 and the end plate 3, which is convenient for adjusting the distance between the clamping arms 10, the driving seats 11 and the clamping seats 14 at the bottom of the hoisting top plate 1 and the end plate 3, so that the distance between the two hoisting seats 4 at the top of the hoisting top plate 1 and the end plate 3 is adapted to the length of the slab to be clamped and lifted;

[0033] During the adjustment, by arranging an adjustment sliding groove 16 in the hoisting top plate 1, it is convenient for the adjusting plate 2 and the sliding bottom plate 17 at its bottom to perform limit sliding, so as to facilitate the adjustment of the distance between the hoisting top plate 1 and the end plate 3. At the same time, in cooperation with the sliding of the limit bolt 19 in the edge through groove 18, the fixing nut 20 is used to conveniently restrict and fix the position of the adjusting plate 2, so as to ensure the stability of the hoisting top plate 1 after the length adjustment, and realize the adjustment and limit of the lateral distance between the two clamping arms 10 and the clamping seats 14, so that the clamping seats 14 can clamp slabs of different lengths;

[0034] After the position adjustment between the hoisting top plate 1, the adjusting plate 2 and the end plate 3 is completed, during the process of limiting and clamping the slab, through the limiting plate 5, the sliding groove 6, the limiting guide groove 7, the sliding seat 8 and the limiting guide block 9, it is convenient for the top of the clamping arm 10 to perform limit guiding sliding inside the limiting plate 5 during the sliding process of the clamping arm 10, which is convenient for subsequent adjustment of the distance between the two clamping arms 10 and the clamping seats 14;

[0035] During the adjustment process, the turntable 13 is rotated to drive the bidirectional driving screw rod 12 to rotate. By the active driving method of the bidirectional driving screw rod 12, the two driving seats 11 are driven to move, so as to drive the two groups of clamping arms 10, the driving seats 11 and the clamping seats 14 to move towards each other and away from each other, so that the clamping seats 14 can effectively clamp the edges of slabs with different width dimensions. The limiting groove 15 inside the clamping seat 14 makes the slab have higher clamping stability during the clamping process, improving the safety of the slab hoisting process;

[0036] By adjusting the distances between the clamping arms 10 and the clamping seats 14 in two different directions, it is convenient for the two clamping seats 14 to more stably limit and clamp slabs with different widths and lengths, so that this adjustable clamping method can adaptively clamp and limit the slabs during the clamping process, ensuring the stability of the slabs during the clamping process.
