Description

Technical Field

[0001] The utility model relates to the technical field of stackers, and particularly relates to a compound guide wheel device for a stacker loading platform and a stacker. Background Art

[0002] The loading platform of the stacker is mainly lifted by steel wires. When lifting, it guides and travels on the guide rail of the column through the guide wheels connected to the loading platform. When walking or picking up goods, due to the unbalanced force, it will also be subjected to a large eccentric load. The structure of the guide wheel determines the stability and safety of the loading platform under force.

[0003] A total of 8 groups of guide wheels in the walking direction and 8 groups of guide wheels in the picking direction are required on the loading platform, and the guide wheels in the walking direction and the picking direction are separately installed on the loading platform; when the stacker accelerates, decelerates, picks up goods on the left, and picks up goods on the right, four groups of guide wheels respectively bear the main pressure. When the load of the stacker is small, the force on the guide wheel is small, and smaller guide wheels can be selected. With the increase of the load and the improvement of safety requirements, the guide wheel set requires a large volume and weight, and it is not convenient to install and arrange the guide wheels with the original structure. In addition, the guide wheel also needs to be closely attached to the column guide rail to better bear the force. Summary of the Invention
