Description

Technical Field

[0001] The utility model relates to the technical field of driving wheel boxes for stackers, in particular to a driving wheel box for an overweight stacker. Background Art

[0002] A stacker crane is a special crane that uses a fork or a skewer as a picking device to grab, transport and stack or pick up and place unit cargo from high-rise shelves in warehouses, workshops, etc. It is a kind of warehousing equipment. A stacker crane is also called a stacker. It is the most important lifting and transportation equipment in a three-dimensional warehouse and a symbol of the characteristics of a three-dimensional warehouse. The main function of a stacker crane is to run back and forth in the aisles of the three-dimensional warehouse, to store the goods at the entrance of the aisle into the cargo compartment of the shelf, or to take out the goods in the cargo compartment and transport them to the entrance of the aisle.

[0003] For example, the authorization announcement number "CN218595195U" is named as an overweight stacker driving wheel box. Although the shaft sleeve is an integrated part, the inner ring processing technology of the corresponding wheel axle is simple, the processing cost is low, and the replaceability is good, but the existing overweight stacker driving wheel box requires a driving motor to drive the driving wheel inside the driving wheel box to rotate, and the materials that the overweight stacker needs to transport are also relatively heavy, so the wear pressure between the track and the driving wheel body will also be relatively large. Therefore, after a long period of operation, the edge of the driving wheel body will be deformed and thinned. Because the edge of the wheel body is hidden inside the overweight stacker driving wheel box, it is difficult for the operator to detect and discover it in time when the wheel body is deformed, which is likely to cause greater losses and reduce the safety of the overweight stacker driving wheel box.

[0004] At the same time, the existing overweight stacker driving wheel box uses a relatively large motor to drive the overweight stacker, and the large motor itself is also very heavy. The current driving motor is arranged on one side of the overweight stacker driving wheel box, while the other side of the overweight stacker driving wheel box lacks a weight balancing structure with the large driving motor. This will cause the side where the motor is installed to sink greatly, while the other side tends to tilt upward, which directly causes the operation process of the overweight stacker driving wheel box to be unbalanced and unstable, affecting the working effect of the overweight stacker driving wheel box.
