The invention belongs to the technical field of traveling cranes, and particularly discloses a liftable multi-stroke traveling crane which comprises a square tube supporting column, a nested square tube, an end beam, a main beam, an auxiliary beam, an X-direction pulley driving mechanism, a first Y-direction pulley driving mechanism and a second Y-direction pulley driving mechanism, and the nested square tube is arranged above the square tube supporting column in a sleeving mode; the end beam is fixed to the top end of the nesting square pipe, the X-direction pulley driving mechanism is arranged on the inner side of the end beam, the main beam is arranged on the X-direction pulley driving mechanism and is perpendicular to the end beam, the first Y-direction pulley driving mechanism is arranged on the main beam, the auxiliary beam is arranged on the first Y-direction pulley driving mechanism and is parallel to the main beam, and the first Y-direction pulley driving mechanism is arranged on the main beam. The second Y-direction pulley driving mechanism is arranged on the secondary beam; the X-direction of the main beam and the auxiliary beam can be adjusted through the X-direction pulley driving mechanism, two-section Y-direction adjustment can be achieved by arranging the first Y-direction pulley driving mechanism and the second Y-direction pulley driving mechanism, and the adjustment range is widened.
本发明属于行吊起重机技术领域,具体公开了一种可升降多行程行吊,包括方管支撑柱、嵌套方管、端梁、主梁、副梁、X向滑轮驱动机构、第一Y向滑轮驱动机构以及第二Y向滑轮驱动机构,所述嵌套方管套设在方管支撑柱上方;端梁固定在嵌套方管的顶端,X向滑轮驱动机构设置在端梁内侧,主梁设在X向滑轮驱动机构上,并且主梁与端梁相互垂直,第一Y向滑轮驱动机构设在主梁上,副梁设置在第一Y向滑轮驱动机构上,副梁与主梁相互平行,第二Y向滑轮驱动机构设置在副梁上;通过X向滑轮驱动机构可以对主梁以及副梁的X方向进行调节,设置第一Y向滑轮驱动机构和第二Y向滑轮驱动机构可以实现两段Y方向调节,提高调节的范围。
