When the movable flaps 121, 122 are rotated to a position where the inner sides are not in contact with the crawler 1100, no crawler 1100 pressing force is applied thereto, and the elastic restoring members 111a, 112a can restore the movable flaps 121, 122.
The specific working principle of the invention is as follows:
When the crawler 1100 is offset by a certain amount, the laser sensor 200 sends a detected signal to the PLC control system, the PLC control system controls the rectification cylinder 600 to operate, the rectification cylinder 600 pushes the push-pull ring 300 to move, then the push-pull ring 300 pushes the multi-lobe outer cylinder 120 to move in the opposite direction of the offset through the end face bearing 700, and when the multi-lobe outer cylinder 120 is pushed to the rectification position, the rectification cylinder 600 is restored to the original position. The movable flaps 121, 122 pressed by the crawler 1100 cannot be restored due to the pressing friction force of the crawler 1100, and the movable flaps 121, 122 not in contact with the crawler 1100 can be restored directly. As the track 1100 is offset, the track 1100 returns to the neutral position as the multi-lobe outer cylinder 120 moves together. When the movable flaps 121 and 122 previously pressed by the crawler 1100 are rotated to the inside as the multi-flap outer cylinder 120 is rotated, the elastic restoring members 111a and 112a restore the movable flaps to the inside, and the one-time deviation correcting operation is completed, so that both the crawler and the multi-flap outer cylinder 120 are restored to the original positions.
In summary, the adjustable track roller disclosed by the invention comprises a central shaft, a multi-flap outer cylinder consisting of at least two movable flaps is sleeved on the central shaft, the central shaft comprises a sliding guide post corresponding to the movable flaps, the movable flaps are arranged on the sliding guide post in a sliding manner, and an elastic reset piece capable of resetting the movable flaps is further arranged on the sliding guide post.
