Bolt device suitable for supporting leg of bridge erecting machine
The invention provides a bolt device for a supporting leg of a bridge girder erection machine, which relates to the technical field of bridge girder erection machines, and comprises a supporting leg upright post, a plurality of first pin holes and a plurality of second pin holes, the lower cross beam is arranged on the supporting leg stand column in a sleeving mode, and a second pin hole is formed in the lower cross beam; the bolt device further comprises a driving mechanism, the driving mechanism is fixed to the lower cross beam, and the driving mechanism is provided with a telescopic rod capable of stretching out and drawing back along a straight line; the axis of the pin shaft is parallel to the axis of the telescopic rod, one end of the pin shaft is fixed to the telescopic rod, and when the second pin hole and the first pin hole are centered, the other end of the pin shaft can penetrate through the second pin hole and the first pin hole at the same time. The overall length and the occupied space of the bolt device can be reduced, and the operation stability of the bolt device is improved.
本发明提供一种用于架桥机支腿的插销装置，涉及架桥机技术领域，其包括：支腿立柱，该支腿立柱沿其轴向均布有若干第一销孔；下横梁，该下横梁套设于该支腿立柱，该下横梁设有第二销孔；该插销装置还包括：驱动机构，该驱动机构固定于该下横梁，且该驱动机构设有可沿直线伸缩的伸缩杆；以及销轴，该销轴的轴线与该伸缩杆的轴线平行，且该销轴一端与伸缩杆固定，当该第二销孔与第一销孔对中时，该销轴另一端可同时贯穿该第二销孔与第一销孔。本发明能够减小插销装置的整体长度和占用的空间，提高插销装置的运行稳定性。
