TRAVELLING MECHANISM FOR BRIDGE DETECTION VEHICLE, AND BRIDGE DETECTION VEHICLE

摘要

The disclosure relates to a bridge inspection vehicle traveling mechanism and a bridge inspection vehicle. The traveling mechanism includes: a frame; a traveling member;a linear telescopic mechanism, one end thereof being hinged to the frame and the other end thereof being hinged to the traveling member, and the linear telescopic mechanism for driving the traveling member to be retracted upwardly or to be grounded downwardly;a second cylinder, one end thereof being hinged to the frame and the other end thereof being rotatable connected to an exterior of the linear telescopic mechanism, the second cylinder for driving the linear telescopic mechanism to be lifted upwards obliquely or to be perpendicular to the ground downwardly. By using the second cylinder to drive the linear telescopic mechanism to be lifted upwards obliquely or to be perpendicular to the ground downwardly, the disclosure can reduce the stroke of the linear telescopic mechanism compared with the prior art. Further, the small stroke of the linear telescopic mechanism and its installation below the frame can further avoid the problem of excessively large stroke of the single cylinder required by lifting height to affect the upper slewing space of the carriage.
