The invention relates to the technical field of crane equipment, and discloses a crane landing leg box structure which comprises a hydraulic oil rod, the hydraulic oil rod is fixedly sleeved with a landing leg box shell, an adjusting rod is movably installed in the middle of an inner cavity of one end of the landing leg box shell, and one end of the adjusting rod is fixedly connected with one end of the hydraulic oil rod; and one end of the hydraulic oil rod is externally and fixedly sleeved with a transmission plate. By arranging the magnetic plate and the electromagnet, the stress effect of the lap joint of the supporting leg box shell and the adjusting rod is reduced, and the problems that the supporting leg box shell deforms and the adjusting rod topples over due to the fact that the stress of the lap joint of the supporting leg box shell and the adjusting rod is too heavy are solved; the supporting leg box body shell and the adjusting rod can be fully and timely counteracted and reduced in stress, the supporting leg box body shell and the adjusting rod are fully protected, the supporting leg box body shell and the adjusting rod are elastically buffered by arranging the protection adjusting air bag, and rigid abrasion is effectively relieved.
本发明涉及起重机设备技术领域,且公开了一种起重机的支腿箱结构,包括液压油杆,所述液压油杆的外部固定套接有支腿箱体壳,所述支腿箱体壳的一端内腔中部活动安装有调节杆,且调节杆的一端与液压油杆的一端固定相连,所述液压油杆的一端外部固定套接有传动板。本发明通过设置磁板和电磁铁,使支腿箱体壳和调节杆的搭接处受力作用变小,避免支腿箱体壳和调节杆搭接处受力过重而导致支腿箱体壳变形,调节杆发生倾倒的问题,通过设置导电电阻件,可以充分且及时的达到对支腿箱体壳和调节杆之间受力的抵消削减,对支腿箱体壳和调节杆实现充分防护,通过设置防护调整气囊,对支腿箱体壳和调节杆之间进行弹性缓冲,有效减轻刚性磨损。
