However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] See also Figure 1-4 The utility model provides a rolling steel support for hot-rolled steel, comprising a support body 1, wherein a coiling roller 7 for rotating the coiled steel is installed inside the support body 1, wherein two device boxes 8 symmetrically arranged in an upper and lower direction and capable of moving toward or away from each other are installed inside the support body 1, wherein a rotating mechanism is installed inside the two device boxes 8, wherein two counter-rotating limiting rollers 6 are installed on the rotating mechanism, and the outer surfaces of the four limiting rollers 6 are all in contact with the outer surfaces of the coiling roller 7, and when the hot-rolled steel is coiled on the rotating coiling roller 7, the distance between the four limiting rollers 6 and the coiling roller 7 is adjusted by adjusting the positions of the two device boxes 8 in a direction toward or away from each other, and the rotating mechanism is used to adjust the distance between the four limiting rollers 6 and the coiling roller 7 until it is adjusted to a suitable thickness for the hot-rolled steel, and when the hot-rolled steel starts to be rolled to the outer surface of the coiling roller 7 again, the problem of deformation of the hot-rolled steel during coiling is avoided by the rotation limiting and clamping of the four limiting rollers 6.

[0022] In order to facilitate the movement of the two device boxes 8 toward or away from each other, by turning on the first motor 2 fixed on a fixed plate 3 and utilizing the rotation of the bidirectional threaded rod 9, the two threaded sleeves 10 threadedly sleeved on the bidirectional threaded rod 9 can be moved toward or away from each other inside the two sliding openings, thereby driving the two device boxes 8 fixed on the two threaded sleeves 10 to adjust their movement toward or away from each other.

[0023] The rotating mechanism mentioned in the above description includes a second motor 4. By turning on the second motor 4 and utilizing the two gears 13 on the two second rotating shafts 18, the two second rotating shafts 18 can rotate synchronously and drive the two rotating blocks 5 to rotate inside the device box 8. The first rotating shaft 11 rotating on the rotating block 5 can drive the limiting roller 6 to perform rotation adjustment and the rotation of the limiting roller 6 itself.

[0024] In order to facilitate the rotation of the two limiting rollers 6 respectively arranged inside the two device boxes 8, the shape of the device box 8 is set to be U-shaped.

[0025] In order to facilitate the coiling roller 7 to coil the hot-rolled steel, a third motor 14 is fixedly connected to one side of the bracket body 1. When the third motor 14 is turned on, the coiling roller 7 is driven to rotate by the connecting shaft, thereby coiling the steel.

[0026] Furthermore, in order to facilitate the limiting of the hot steel coil entering the interior of the bracket body 1 when coiling the steel, electric cylinders 12 are fixedly connected to the top and bottom of one side of the inner cavity of the bracket body 1. The extension and retraction of the two electric cylinders 12 drive the two connecting blocks 15 to control the positions of the two feeding rollers 16 rotating on the connecting blocks 15, thereby facilitating the clamping and feeding of the hot-rolled steel entering the interior of the bracket body 1 through the opening by the two feeding rollers 16.
