在铁路工厂中,利用转盘实现机车、车辆和转向架的调头、转位是十分普遍的。过去所用的转盘有用人力推动和电驱动两种,都采用环形钢轨和滚动轮对结构。本文介绍一种根据气垫原理设计制造的新型转盘——承重14吨的气垫式转盘,其状态如图1。 In railway factories, the use of turntables to achieve locomotives, vehicles and bogies U-turn, indexing is very common. Turntable used in the past useful human and electric drive to promote both types, both using circular rails and rolling wheel on the structure. This article describes a new type of turntable designed and manufactured according to the principle of air cushion - bearing 14 tons of air-cushion turntable, the state shown in Figure 1.
