摘 要
拖掛式混凝土泵是目前在建筑工程中廣泛應(yīng)用的主要混凝土機械之一。一般混凝土泵的工作機構(gòu)是由推送機構(gòu)、分配閥及料斗的攪拌裝置組成，因而液壓式混凝土泵的液壓系統(tǒng)同樣也包括這三個工作機構(gòu)：推送機構(gòu)回路即主油路系統(tǒng)、分配閥油路系統(tǒng)及攪拌油路系統(tǒng)。主要采用全液壓傳動方式。它可以較好的使用于建筑工程中，工作范圍廣。正常工作時，不需要其它附屬設(shè)備，使用機動靈活。最近幾年，在建筑工程推廣應(yīng)用的泵送混凝土技術(shù)，以其效率高、費用低、節(jié)省勞力、水平和垂直運輸可一次連續(xù)完成、使用狹窄施工現(xiàn)場等優(yōu)點，愈來愈受到人們的重視。
本設(shè)計圍繞著當(dāng)今拖掛式混凝土泵的特點，主要設(shè)計以下相關(guān)問題：
首先，介紹了混凝土泵在國內(nèi)國外的發(fā)展歷史和狀況。
其次，著重討論了混凝土泵主要設(shè)計方案的確定。通過多種形式的比較，最終選定其液壓系統(tǒng)、泵送系統(tǒng)、分配閥系統(tǒng)、攪拌系統(tǒng)、擺動系統(tǒng)的解決方案。
然后，對具體相關(guān)所需數(shù)字進行計算和條件校核。從而確定了整個混凝土泵的設(shè)計。
最后，在對其會出現(xiàn)的一些故障等進行說明，并敘述怎樣進行維修。

Abstract
Tuogua concrete pump is widely used in the construction of one of the main concrete machinery. General concrete pump from the work of agencies is pushing institutions, distribution of the mixing valve and the hopper device components, thus hydraulic concrete pump the hydraulic system also includes the work of these three institutions: Push agencies loop system that is the main Circuit, Distribution systems and mixing valve Circuit system. All the main use of hydraulic transmission mode. It can be better used in construction, the scope of work. Normal working hours, do not need other ancillary equipment, the use of mobile and flexible. In recent years, popularization and application of the construction of pumping concrete technology, with its high efficiency, low-cost, labour-saving, horizontal and vertical transportation to complete the first row, the use of the advantages of a narrow construction site, people are more and more attention.
The contemporary design around the concrete pump Tuogua the characteristics of the main design issues related to the following.
First of all, on the concrete pump in the history of the development of domestic and foreign situation.
Second, focus on the concrete pump design options determination. Through various forms of comparison, the final selection of its hydraulic system, pumping systems, distribution valve system, stirring, swinging system solutions.
Then, on specific figures related to the required calculations and check conditions. To determine the entire concrete pump design.
Finally, there will be some of their faults, such as a description, and describes how to carry out repairs.
Keywords: Tuogua concrete pumps, hydraulic system, swing system, stirring system, pumping system.
