The quay crane comprises a front girder, a rear girder, a traction steel wire rope, a trolley, a cab and a carrier roller support, one end of the front girder is hinged to one end of the rear girder, the trolley is movably connected to the front girder and the rear girder, and the traction steel wire rope is connected with the trolley and drags the trolley to move on the front girder and the rear girder; the cab is mounted on the trolley; the carrier roller support is mounted at the joint of the front girder and the rear girder; the carrier roller support comprises a connecting assembly and a carrier roller, the connecting assembly is installed at the connecting position, the carrier roller is installed on the connecting assembly, when the front girder tilts up relative to the rear girder, the steel wire rope winds around the carrier roller, and the carrier roller is adjustable at least in the first direction relative to the connecting assembly. Therefore, in the quay crane, the position of the carrier roller can be adjusted, the theoretical length of the steel wire rope connected with the carrier roller can be adjusted, and when the front girder of the quay crane is lifted up, the position of the cab relative to the girder can be ensured to be unchanged by adjusting the position relation of the carrier roller relative to the steel wire rope.

    本发明公开了一种岸桥,包括前大梁、后大梁、牵引钢丝绳、小车、司机室和托辊支座,前大梁的一端与后大梁的一端铰接,小车移动连接于前大梁以及后大梁,牵引钢丝绳连接小车并牵引小车在前大梁以及后大梁上移动;司机室安装于小车上;托辊支座安装于前大梁和后大梁的连接处;托辊支座包括连接组件和托辊,连接组件安装于连接处,托辊安装于连接组件上,前大梁相对于后大梁仰起时,钢丝绳绕过托辊,托辊相对于连接组件至少沿第一方向可调。可见,该岸桥中,能够实现托辊位置调节,能够调节与托辊连接的钢丝绳的理论长度,当岸桥的前大梁仰起时,能够通过调节托辊相对于钢丝绳的位置关系来保证司机室相对于大梁上的位置不变。
