Curve beam erecting method
The invention provides a curved beam erection method, and relates to the technical field of railway construction, and the method comprises the following steps: enabling a bridge girder erection machine to pass through a hole; shifting the front end of the arm of the bridge girder erection machine out of the curve, and shifting the middle part of the arm of the bridge girder erection machine into the curve so as to determine the front hoisting point position and the rear hoisting point position of the bridge girder erection machine and realize that the rear end of the bridge girder erection machine is close to the curve; a third column of the bridge girder erection machine is turned upwards by 90 degrees and runs to the position below the bridge girder erection machine through a front girder transporting vehicle and a rear girder transporting vehicle which bear the girder pieces, so that a girder piece front lifting hole in the front girder transporting vehicle is transversely aligned with the position of a front lifting point; a beam carrying trolley of a front beam carrying vehicle moves forwards relative to a main vehicle of the front beam carrying vehicle, and a rear beam carrying vehicle moves along with the beam carrying trolley of the front beam carrying vehicle, so that a beam piece front lifting hole is longitudinally aligned with the position of a front lifting point; a camel beam trolley of the rear beam transporting vehicle transversely moves relative to a main vehicle of the rear beam transporting vehicle, so that a beam piece rear hoisting hole is transversely aligned with a rear hoisting point in position and longitudinally aligned with the rear hoisting point in position; according to the method, the efficiency of curved beam erection is improved.
本发明提供了一种曲线梁架设方法，涉及铁路施工技术领域，该方法包括：使架桥机过孔；使架桥机的机臂前端向曲线外偏移，同时使架桥机的机臂中部向曲线内偏移，以确定架桥机的前吊点位置和后吊点位置，同时实现架桥机的后端靠近曲线；将架桥机的三号柱向上翻转90°，通过承载有梁片的前运梁车和后运梁车运行至架桥机的下方，以使前运梁车处的梁片前吊孔与前吊点位置横向对齐；通过前运梁车的驼梁台车相对前运梁车的主车前移，以及后运梁车随前运梁车的驼梁台车移动，以使梁片前吊孔与前吊点位置纵向对齐；通过后运梁车的驼梁台车相对后运梁车的主车横移，以使梁片后吊孔与后吊点位置横向对齐以及纵向对齐；该方法提高了曲线梁架设的效率。
