[0002] A stacker is a type of handling equipment used for loading, unloading, stacking and short-distance transportation of goods. It can be divided into rail-mounted aisle stackers and trackless stackers according to the different mobile guidance methods. The rail-mounted aisle stacker lays mobile tracks on the ground, allowing the stacker to shuttle between shelves in the aisle, thereby loading, unloading and transporting designated goods.

[0003] The turning wheel box is a type of wheel box that supports and assists the movement of the stacker. The turning function of the stacker is achieved through the cooperation between the turning wheel box and the moving track. In the prior art, most of the turning wheel boxes are assembled mainly by rotating the shaft and the lower crossbeam of the stacker, and the shaft and the lower crossbeam of the stacker are connected by a slewing bearing. Although the slewing bearing can be used to limit the assembly of the shaft of the turning wheel box, it has problems such as poor sealing effect and poor rotation flexibility, which makes the turning wheel box prone to derailment and bearing damage during use. At the same time, the turning wheel box cannot tighten the connecting cable, which makes the connecting cable wear and tear during the movement of the turning wheel box, resulting in poor reliability and high operation and maintenance costs.

[0038] like Figures 1 to 3 As shown, a slewing bearing 208 is installed between the guide wheel 207 and the guide rod 206. The slewing bearing 208 plays the role of connecting the guide rod 206 and the guide wheel 207, and the guide wheel 207 is rotatably assembled on the outer side of the guide rod 206 through the slewing bearing 208.

At the same time, the two ends of the connecting cable 304 are passed through the storage slot on the outside of the tightening inner shell 302, and are led out along the avoidance hole on the outside of the outer limit ring 3013. The winding of the clockwork spring 303 drives the tightening inner shell 302 to rotate in the tightening box 301. The tightening inner shell 302 can be wound around the outside of the tightening inner shell 302 through the rotation of the tightening inner shell 302 and the snap-fitting of the storage slot. The connecting cable 304 is tightened by the winding and resetting of the clockwork spring 303, thereby reducing the wear and damage of the connecting cable 304 during movement.
