【摘要】 滑移装船是平台导管架和平台组块等大型结构物施工过程的重要环节,该技术取代了传统采用浮吊的施工方法,大幅度地降低了成本。目前,大型结构物的滑移装船都是由技术人员靠简单的工具现场检测潮汐变化以及结构物移动距离,通过这些参数计算出驳船的调载水量,指挥整个拖拉工程。这种方法存在着多种误差和不确定的因素,给施工过程带来了安全隐患。 论文在系统分析滑移装船控制过程的基础上将自动测量技术和软件集成技术应用到船舶控制,增加了码头关键点的力反馈控制,对滑移装船的位移进行实时监测,提高了滑移装船的安全性、可靠性和自动化程度,有着重要的工程实用价值和应用背景。本文主要的研究内容包括: 1.根据对结构物施工工艺过程的研究,分析了不同结构物形式滑移装船过程的设计以及环境因素对滑移装船的影响,探讨了影响驳船稳性的因素。 2.根据装船过程驳船受力分析建立了基于码头受力反馈控制的调载水量数学模型,通过对水泥垫墩的受力检测,修正调载数据。 3.进行了计算机检测系统硬件的设计。系统以工控机为控制系统的核心,采用RS485网络进行通讯,由弦振式应变测量系统、潮位传感器、激光测距仪等组成数据采集系统。 4.编制了具有力反馈控制的调载计算软件。建立了系统设备、驳船和大型结构物的信息数据库;并开发了检测控制模块、通讯模块和数据处理模块。 5.论文进行了实验仿真,通过比较了结构物滑移装船在多种不同工况下的计算数据,对基于力反馈的调载水量模型及软件进行了验证。更多还原

【Abstract】 Slippage shipment is one of the shipment technologies of large structure including platform jackets and platform blocks, by which the classic construction method is replaced for greatly decreasing the cost. But now the shipment is controlled by the technician, detecting the change of tide and movement distance to calculate the weight adjustment, which is impossible to ensure the safety.In this paper, based on the systemic analysis of shipment control process, auto-measure technology and software integration technology are used to deal with the barge control, and force feedback of dock key points is applied, which improves the veracity, security and reliability of the shipment which has important engineering and application foreground. The main research of this paper can be included as follows:1. Based on the research of structure construction process, the influence of design for different style of structure shipment and environment factors is analyzed and qualification that influences the barge stability is also discussed.2. According to the barge force analysis the mathematic module of automatic water ballast adjustment based on force feedback is built and the adjustment water data is modified by force detection about cerement bracket.3. The hardware design of the system that is built with industrial computer as its center, RS485 as its communication, data collection system consisting of string vibration strain detection system, tide sensor and laser telemeter.4. Software development is done to the system, which is made up of systemic equipment, barge and large structure database, data processing module, measure control module and communication module.5. Carry out the experiment simulation and through comparing the calculation data from three different conditions of shipment of two slide styles, the water adjustment module and software is testified.更多还原
