The invention belongs to the technical field of crane supporting legs, and particularly relates to a crane supporting leg. The crane supporting leg comprises a hydraulic rod, a cross beam, a servo hydraulic motor and an adjusting module. When the height of the cross beam is adjusted, the servo hydraulic motor controls a second transmission sleeve to rotate, so that when the hydraulic rod stretchesout and draws back, an internal thread area on the first transmission sleeve and an external thread area on a supporting leg are staggered, the hydraulic rod can slide smoothly, and then the supporting leg is driven to slide up and down to adjust the height; when the hydraulic rod stretches to the position and stops stretching, the servo hydraulic motor controls the first transmission sleeve to be matched with the internal thread area and the external thread area on the supporting leg, and up-down movement of the supporting leg is locked; and the supporting effect on the cross beam is achieved, and one more guarantee is provided for supporting of the cross beam.

    本发明属于吊车支腿技术领域,尤其涉及一种吊车支腿,它包括液压杆、横梁、伺服液压马达、调节模块,在调节横梁高度的时候,通过伺服液压马达控制第二传动套旋转,使得液压杆在伸缩的时候,第一传动套上的内螺纹区域与支腿上外螺纹区域错位,液压杆可以顺利滑动,进而带动支腿上下滑动,调节高度,当液压杆伸缩到位置停止伸缩的时候,伺服液压马达控制第一传动套和支腿上的内螺纹区域和外螺纹区域配合,将支腿的上下移动锁死;对横梁起到支撑作用,为横梁的支撑提供了多一种保障。
