　　隨著建筑行業(yè)的智能化程度越來越高，很多建筑機(jī)械已經(jīng)代替了人工作業(yè)，大大的提高了工作效率，降低了人力成本的支出。混凝土輸送泵，又稱混凝土泵，由泵體和輸送管組成，是一種利用壓力將混凝土沿管道連續(xù)輸送的機(jī)械，主要應(yīng)用于房建、橋梁及隧道施工。為了提高輸送泵的移動(dòng)性，一般將泵體裝在汽車底盤上，再裝備可伸縮或屈折的布料桿，構(gòu)成輸送泵車。目前，主要分為閘板閥混凝土輸送泵和S管閥混凝土輸送泵。
　　設(shè)備結(jié)構(gòu)及基本性能
　　本項(xiàng)目以山東某設(shè)備產(chǎn)商WF型輸送泵車為例，其主要部件混凝土輸送泵由料斗、泵送系統(tǒng)、液壓系統(tǒng)、清洗系統(tǒng)、電氣系統(tǒng)、電動(dòng)機(jī)、行走底盤等組成。
　　泵送機(jī)構(gòu)由2只主缸水箱、換向裝置、2只混凝土缸、2只混凝土活料斗、分配閥(S形閥)、擺臂、2只擺動(dòng)液壓缸和出料口組成。整機(jī)性能和液壓系統(tǒng)參數(shù)分別如表1、表2所示。
　工藝原理
　　混凝土活塞分別與主液壓缸活塞桿連接，在主液壓缸液壓油作用下，作往復(fù)運(yùn)動(dòng)，一缸前進(jìn)，則另一缸后退;混凝土缸出口與料斗連通，分配閥一端接出料口，另一端能過花鍵軸與擺臂連接，在擺動(dòng)液壓缸作用下，可以左右擺動(dòng)。
　　泵送混凝土料時(shí)，在主液壓缸作用下，混凝土活塞可前進(jìn)或后退。同時(shí)在擺動(dòng)液壓缸作用下，分配閥與混凝土缸連通，混凝土缸與料斗連通。這樣混凝土活塞后退，便將料斗內(nèi)的混凝土吸入混凝土缸，混凝土活塞前進(jìn)，將混凝土缸內(nèi)混凝土料送入分配閥泵出。
　　當(dāng)混凝土活塞后退至行程終端時(shí)，觸發(fā)水箱中的換向裝置，主液壓缸換向，同時(shí)擺動(dòng)油缸換向，使分配閥與混凝土缸連通，混凝土缸與料斗連通，這時(shí)活塞后退前進(jìn)依次循環(huán)，從而實(shí)現(xiàn)連續(xù)泵送。
　　反泵時(shí)，通過反泵操作，使處在吸入行程的混凝土缸與分配閥連通，處在推送行程的混凝土缸與料斗連通，從而將管路中的混凝土抽回料斗。
　　泵送系統(tǒng)通過分配閥的轉(zhuǎn)換完成混凝土的吸入與排出動(dòng)作，因此分配閥是混凝土泵中的關(guān)鍵部件，會(huì)直接影響到混凝土泵的性能。
　　方案選型
　　該設(shè)備所需的控制點(diǎn)數(shù)為數(shù)字量輸入12點(diǎn)，數(shù)字量輸出8點(diǎn)。其中主要的輸入輸出點(diǎn)為正泵、反泵、遠(yuǎn)控/近控、主缸進(jìn)/退、擺缸進(jìn)/退、高壓 /低壓、電動(dòng)機(jī)起動(dòng)/停止、2個(gè)接近開關(guān)、4個(gè)電磁閥、指示燈運(yùn)行指示。I/O點(diǎn)設(shè)置如表3所示。
　　由于該設(shè)備主要銷往海外市場(chǎng)，設(shè)備廠商在電控系統(tǒng)選型時(shí)主要考慮產(chǎn)品的高可靠性和品牌知名度。前者保證設(shè)備穩(wěn)定運(yùn)行，最大限度降低售后服務(wù)的成本，甚至無需售后服務(wù);后者有助于提升設(shè)備整體的品牌，提升在海外市場(chǎng)的競(jìng)爭(zhēng)力。
