[0056] Working process:

[0057] When this solution is implemented, the roller 1 is initially in a low position, and the roller 1 waits for the slab to be transported. After the slab is completely transported to the roller 1, the lifting hydraulic cylinder 2 extends, and the roller 1 is lifted to a predetermined height along the designed trajectory under the restriction of the swing arm 8. At the same time, an electrical component synchronously detects the position of the roller 1. After the electrical component receives the signal that the roller 1 has reached the predetermined position, the hydraulic cylinder 2 stops moving and brakes with pressure. After the roller 1 continues to transport the slab to the high transport section, the hydraulic cylinder 2 retracts and the roller 1 returns to the initial position. The equipment is also equipped with two buffer components 3 to intercept the slab transported from a low position. The buffer component 3 prevents the slab from being damaged due to collision during transportation. The buffer component 3 is used to receive the roller 1 when the roller 1 descends, which reduces the impact of the equipment and increases the life of the equipment.

[0058] Compared with the traditional method of driving the roller table 1 up and down by multiple worm gear lifts, the roller table 1 is driven up and down by the hydraulic cylinder 2, and the swing arm 8 ensures the movement trajectory of the roller table 1 during the lifting process, and the movement process is more stable.
