The invention provides a folding arm gooseneck type quay crane girder manufacturing method, a quay crane girder comprises a front girder seaside section, a front girder landside section and a rear girder, and the method is characterized by comprising the steps that S1, measurement datum points are arranged on the front girder seaside section, the front girder landside section and the rear girder respectively; s2, using a straightness adjusting jig frame to adjust the straightness of the front crossbeam sea side section, the front crossbeam land side section and the rear crossbeam by taking the measurement datum point as a datum; s2, using a horizontal adjustment jig frame to adjust the front crossbeam sea side section, the front crossbeam land side section and the rear crossbeam to be horizontal by taking the measurement reference point as a reference; s3, rigidly fixing the front crossbeam seaside section, the front crossbeam landside section and the rear crossbeam; and S4, the gooseneck hinge point reamed hole and the first hinge point reamed hole are bored. According to the girder manufacturing method, the straightness adjusting jig frame and the horizontal adjusting jig frame are used for aligning the girder, and the assembling precision of the girder is effectively improved.
本申请提供一种折臂鹅颈式岸桥大梁制造方法,岸桥大梁包括:前大梁海侧段、前大梁陆侧段以及后大梁,其特征在于,包括:S1、分别在前大梁海侧段、前大梁陆侧段以及后大梁上设置测量基准点;S2、以测量基准点为基准,使用直线度调整胎架对前大梁海侧段、前大梁陆侧段以及后大梁直线度进行调整;S2、以测量基准点为基准,使用水平调整胎架调整前大梁海侧段、前大梁陆侧段以及后大梁水平;S3、将前大梁海侧段、前大梁陆侧段以及后大梁刚性固定;S4、对鹅颈铰点铰孔和第一铰点铰孔进行镗孔。本申请的大梁制造方法使用直线度调整胎架和水平调整胎架对大梁进行对正,有效提高了大梁的组装精度。
