Description

Technical Field

[0001] The utility model relates to the technical field of RGV power vehicle turntables, in particular to a gear pin turntable of an RGV power vehicle. Background Art

[0002] The RGV power vehicle can run along the track. If the RGV power vehicle needs to be reversed, the existing method is to hoist the RGV power vehicle from the original track, turn it, and then place it on the track. In this process, the disadvantage is that the efficiency of the hoisting equipment is low, and the hoisting steel cable needs to be manually hooked to the RGV power vehicle, which makes the existing RGV power vehicle inconvenient when reversing. In addition, when the RGV power vehicle is reversing in multiple directions, the hoisting equipment needs to be used to rotate the RGV to other directions, which is extremely difficult and the effect is not good. It is very necessary to provide a simpler and more efficient RGV reversing device. Utility Model Content
