　　随着建筑行业的智能化程度越来越高，很多建筑机械已经代替了人工作业，大大的提高了工作效率，降低了人力成本的支出。混凝土输送泵，又称混凝土泵，由泵体和输送管组成，是一种利用压力将混凝土沿管道连续输送的机械，主要应用于房建、桥梁及隧道施工。为了提高输送泵的移动性，一般将泵体装在汽车底盘上，再装备可伸缩或屈折的布料杆，构成输送泵车。目前，主要分为闸板阀混凝土输送泵和S管阀混凝土输送泵。
　　设备结构及基本性能
　　本项目以山东某设备产商WF型输送泵车为例，其主要部件混凝土输送泵由料斗、泵送系统、液压系统、清洗系统、电气系统、电动机、行走底盘等组成。
　　泵送机构由2只主缸水箱、换向装置、2只混凝土缸、2只混凝土活料斗、分配阀(S形阀)、摆臂、2只摆动液压缸和出料口组成。整机性能和液压系统参数分别如表1、表2所示。
　工艺原理
　　混凝土活塞分别与主液压缸活塞杆连接，在主液压缸液压油作用下，作往复运动，一缸前进，则另一缸后退;混凝土缸出口与料斗连通，分配阀一端接出料口，另一端能过花键轴与摆臂连接，在摆动液压缸作用下，可以左右摆动。
　　泵送混凝土料时，在主液压缸作用下，混凝土活塞可前进或后退。同时在摆动液压缸作用下，分配阀与混凝土缸连通，混凝土缸与料斗连通。这样混凝土活塞后退，便将料斗内的混凝土吸入混凝土缸，混凝土活塞前进，将混凝土缸内混凝土料送入分配阀泵出。
　　当混凝土活塞后退至行程终端时，触发水箱中的换向装置，主液压缸换向，同时摆动油缸换向，使分配阀与混凝土缸连通，混凝土缸与料斗连通，这时活塞后退前进依次循环，从而实现连续泵送。
　　反泵时，通过反泵操作，使处在吸入行程的混凝土缸与分配阀连通，处在推送行程的混凝土缸与料斗连通，从而将管路中的混凝土抽回料斗。
　　泵送系统通过分配阀的转换完成混凝土的吸入与排出动作，因此分配阀是混凝土泵中的关键部件，会直接影响到混凝土泵的性能。
　　方案选型
　　该设备所需的控制点数为数字量输入12点，数字量输出8点。其中主要的输入输出点为正泵、反泵、远控/近控、主缸进/退、摆缸进/退、高压 /低压、电动机起动/停止、2个接近开关、4个电磁阀、指示灯运行指示。I/O点设置如表3所示。
　　由于该设备主要销往海外市场，设备厂商在电控系统选型时主要考虑产品的高可靠性和品牌知名度。前者保证设备稳定运行，最大限度降低售后服务的成本，甚至无需售后服务;后者有助于提升设备整体的品牌，提升在海外市场的竞争力。
