Intelligent three-main-truss steel truss girder closure rising and falling beam control method
The invention discloses an intelligent three-main-truss steel truss girder closure rising and falling beam control method. The method is particularly suitable for a three-main-truss steel truss girderwhich is influenced by temperature, large in measurement difficulty and difficult to control in line shape. The method comprises the steps that a, a space Beidou satellite is adopted for positioningrod piece nodes on the side span side and the main pier side of a three-main-truss steel truss girder closure gap, and positioning information is transmitted to an intelligent computer; b, the intelligent computer analyzes the received positioning information, calculates a force value needing to be applied to each pier top according to an analysis result of the positioning information, and transmits the force value information as an operation instruction to full-automatic hydraulic jacks arranged in the vertical direction of each pier top; c, the full-automatic hydraulic jacks arranged on thepier tops in the vertical direction are adjusted according to the operation instruction; and d, the steps are repeated till the position deviation between the rod pieces on the two sides of the closure gap is within the error range. According to the method, the three-dimensional coordinates of the closure gap rod piece can be accurately measured, rapid closure of the closure port is facilitated, meanwhile, the regulation and control equipment is remotely controlled through a computer, the construction procedure of manual regulation and control is simplified, and the regulation and control efficiency of the rising and falling beam is improved.
本发明公开了一种智能化三主桁钢桁梁合龙起落梁控制方法，特别适用于受温度影响测量难度大和线形难以控制的三主桁钢桁梁。包括的步骤为：a，采用空间北斗卫星对三主桁钢桁梁合龙口边跨侧和主墩侧的杆件节点进行定位，将定位信息传输给智能计算机；b，智能计算机对收到的定位信息进行分析，同时根据定位信息分析结果计算出需要施加在各个墩顶的力值，并将力值信息作为操作指令传输到布置在各个墩顶竖向的全自动化液压千斤顶；c，布置在各个墩顶竖向的全自动液压千斤顶根据操作指令实施调整；d，重复上述步骤，直到合龙口两侧杆件之间的位置偏差达到误差范围内。本发明能够精准测量合龙口杆件的三维坐标，有助于合龙口的快速合龙，同时通过电脑远程控制调控设备，简化了人为调控的施工工序，提高了起落梁的调控效率。
