Intelligent cable tightening machine for main cable of suspension bridge and cable tightening method
The invention belongs to the technical field of suspension bridge main cable tightening construction, and particularly relates to an intelligent cable tightening machine for a suspension bridge main cable and a cable tightening method. The device comprises a walking mechanism, a squeezing device, a hydraulic pump station, a counterweight frame, a controller and a pull rope displacement sensor. The controller is connected to the counterweight frame; each hydraulic jack is connected with a pull rope displacement sensor; and each pull rope displacement sensor and the hydraulic pump station are respectively in electric signal connection with the controller. Three groups of diameters are actually measured through the six pull rope displacement sensors, the real-time void ratio and the out-of-roundness ratio are obtained through the three groups of diameter values, and then adjustment is implemented through operation of the hydraulic pump station. According to the method, the construction organization problems that the error of conventional manual jack pressure value reading is large and the efficiency of manual porosity calculation is low are solved, the data error of a hydraulic system is reduced, the calculation efficiency and accuracy are improved by calculating the porosity through the system, and the main cable tightening construction efficiency is greatly improved.
本发明属于悬索桥主缆紧缆施工技术领域，具体涉及一种悬索桥主缆智能紧缆机及紧缆方法。本发明包括行走机构、挤紧装置、液压泵站、配重架、控制器和拉绳位移传感器；控制器连接在配重架上；每个液压千斤顶上连接有一个拉绳位移传感器；每个拉绳位移传感器及液压泵站分别与控制器电信号连接。本发明通过6个拉绳位移传感器，实际测出3组直径，通过3组直径值得出实时空隙率及不圆率，之后通过液压泵站操作实施调整。本发明解决了常规人工读数千斤顶压力值误差大和手动计算孔隙率效率低的施工组织问题，减小了液压系统数据误差，通过系统计算孔隙率提高了计算的效率和准确度，大大提高了主缆紧缆施工效率。
