Multifunctional shifting trolley suitable for descending type bridge girder erection machine
The multifunctional shifting trolley comprises a lower-layer frame arranged on a main supporting leg, the lower-layer frame is rotatably connected with an upper-layer frame through a horizontal rotating mechanism, a lower hook connected with the main supporting leg is arranged at the bottom of the lower-layer frame, and an upper hook connected with a main beam is arranged above the upper-layer frame; the upper-layer frame is connected with a longitudinal moving mechanism for driving the main beam to longitudinally move, and the lower-layer frame is connected with a transverse moving mechanism for driving the trolley to transversely move; the trolley has the beneficial effects that relative horizontal rotation between the upper-layer trolley frame and the lower-layer trolley frame can be achieved through the horizontal rotation mechanism so that the trolley can better adapt to construction in a curve state; the longitudinal moving mechanism is used for driving the main beam to move longitudinally, the pin shafts do not need to be manually replaced during long-distance one-way longitudinal moving, and the frequency of manually replacing the pin shafts can be reduced during long-distance two-way longitudinal moving.
本发明公开了一种适用于下行式架桥机的多功能移位台车，包括设置在主支腿上的下层车架，下层车架通过平转机构可旋转地连接上层车架，下层车架底部设置有连接主支腿的下钩挂，上层车架上方设置有连接主梁的上钩挂；上层车架连接有驱动主梁纵移的纵移机构，下层车架连接有驱动台车横移的横移机构；本发明所具有的有益效果为：平转机构可实现上层车架和下层车架之间的相对平转，以更好地适应曲线状态的施工；纵移机构用于驱动主梁纵移，在长距离单向纵移时无需人工倒换销轴，在长距离双向纵移时可减少人工倒换销轴的次数。
