Precast box girder carrying trolley
The invention discloses a prefabricated box girder carrying trolley, and relates to the technical field of the rail traffic equipment industry, the prefabricated box girder carrying trolley comprises a rail, the top of the rail is provided with a girder moving trolley, the top of the girder moving trolley is provided with a centering correction mechanism, the centering correction mechanism comprises a spring A, one end of the spring A is fixedly connected with the upper portion of the girder moving trolley, and the other end of the spring A is fixedly connected with the lower portion of the girder moving trolley. Bottom plates are fixedly connected to the two sides of the inner wall of the beam moving trolley, and support plates are fixedly connected to the top ends of springs A. By arranging a centering correction mechanism, the effect of automatically correcting the position of a box beam is achieved, so that the situation that the box beam is obliquely placed on the beam moving trolley and consequently uneven stress is caused is avoided, and meanwhile the situation that when the beam moving trolley moves subsequently, the box beam is damaged is avoided. The problems that the surface stress and the internal stress of the box girder are rapidly changed and cracks occur due to vibration generated by different heights of the rails are solved, then a large amount of time wasted by workers for controlling the box girder to be placed in the middle is greatly shortened, and the working efficiency is improved.
本发明公开了一种预制箱梁搬运小车，涉及轨道交通装备产业技术领域，包括铁轨，所述铁轨顶部设置有移梁小车，所述移梁小车顶部设置有居中校正机构，所述居中校正机构包括，弹簧A，所述弹簧A一端与移梁小车上方固定连接，所述移梁小车内壁两侧固定连接有底板，所述弹簧A顶端固定连接有支架板，通过设置居中校正机构，实现自动纠正箱梁位置的作用，从而避免箱梁放置在移梁小车上的放置歪斜，而导致受力不均匀，也同时避免在后续移梁小车移动时，由于轨道高低的不同而产生的震动，导致箱梁表面与内部应力发生快速变化，而出现裂纹的问题，继而也大幅减少了工作人员控制进行居中放置箱梁所浪费的大量时间，提升工作效率。
