路桥建设的不断发展，要求配套的起重机械能够满足其工作要求，不但要求能实现最基本的起重搬运要求，而且现代建设工作越来越要求其便捷性，经济型、环保性。为适应大型路桥建设工程的需要，现阶段人们在原来起重机械的基础上，进行各种新型起重机械的研究。
本设计针对路桥架设过程中博格板的搬运工作要求，设计一种新型起重机械——架桥龙门起重机的液压系统，架桥龙门起重机主要由四个部分组成，即：起升机构、小车行走机构、转向机构和大车行走机构。根据这四个机构不同的工作特点、实际工况的需要以及整个液压系统的工作形式对这四个系统以及供油系统分别进行设计。通过对这四个部分分别进行系统设计计算、标准件选型、非标准件的设计绘图以及液压辅件的设计与选型，完成整个系统的设计。

Continuously develop of the road bridge construction, the derrick that requests the kit can satisfy it works to request, not only request to can carry out the most basic since heavy porterage request, but also the modern construction work more and more request it convenience, economic type, environmental protection.In order to adapt the demand that the large road bridge constucts the engineering, currently people at originally the foundation of the derrick up, carry on the research of various new derrick .
This design installs the process to the road bridge in the space knothole porterage work request, design a kind of new derrick - build a bridge the Dragon gate derrick of liquid press the system, build a bridge the Dragon gate derrick to mainly be constitute by four parts, namely:Rise to rise the organization, small garage to walk organization, change direction the organization and big garages to walk organization.Press the work form of the system according to demand
