Description

Technical Field

[0001] The utility model relates to the technical field of stackers, in particular to a stacker overhead rail guide device. Background Art

[0002] As the most important lifting and transportation equipment in a high-bay warehouse, the stacker crane's main function is to run back and forth along the bottom ground rail and the top ceiling rail, storing the goods at the aisle entrance into the shelves' cargo compartments, or taking the goods out of the cargo compartments and transporting them to the aisle entrance. The ceiling rail is a profile fixed to the top beam of the shelf. It is arranged along the entire length of the aisle and extends to the outside of the shelf. It is used in conjunction with the guide wheels on the crossbeam of the stacker crane to provide horizontal support and ensure the horizontal operation of the stacker crane. For stackers of super-high, super-heavy, and high-speed types, it is often necessary to increase the diameter or thickness of the guide wheels to meet the load-bearing capacity of the guide wheels. As a result, the cross-sectional dimensions of the ceiling rails become larger accordingly, and the top space dimensions also need to be increased, which may eventually lead to a decrease in the volume ratio of the high-bay warehouse. In addition, the increase in the variety of guide wheel specifications is even more detrimental to procurement and production organization and supporting management. Utility Model Content

[0006] The use of double guide wheels increases the load-bearing capacity of the guide device to meet the use requirements. The guide wheels are universalized without changing the size of the top space, so that the volume ratio of the three-dimensional warehouse is maximized. The double guide wheels can rotate on their own and can also rotate based on the support seat to achieve balanced force on the double guide wheels, thereby improving the load-bearing capacity of the guide device.

[0007] Furthermore, a support plate is provided on the guide wheel seat, and a guide wheel shaft for installing the guide wheel is fixedly provided on the support plate.

[0011] Furthermore, the number of the guide wheels is eight.

[0012] Compared with the existing technology, the beneficial effects of the present invention are:

[0013] 1. A stacker crane overhead rail guide device uses dual guide wheels to increase the guide device's load-bearing capacity to meet usage requirements. The universal guide wheels do not change the size of the top space, maximizing the volume ratio of the three-dimensional warehouse.
