拖式混凝土泵导向轮有如下功能：缓慢拖行时的导向作用；固定不动时的支承作用；支起支腿时起千斤顶的作用；收起轮子方便运输的作用。 旧型号拖泵采用一对锥齿轮传动，上下共有三套轴支座，总共６０多个零件，结构复杂，制造困难，成本高，故障多。我们参考国外拖泵导向轮的设 The trailing concrete pump guide wheel has the following functions: guiding action when dragging slowly; supporting function when fixed; fixing the jack when supporting the leg; retracting the wheel to facilitate transportation. The old model of the pump used a pair of bevel gears, there are three sets of shaft bearings up and down, a total of more than 60 parts, the structure is complex, difficult to manufacture, high cost, failure and more. We refer to the design of foreign tractor guide wheels
