The invention discloses a polymorphic walking mechanism for a crane. The polymorphic walking mechanism comprises a crane body, two supporting frames are fixedly installed at the bottom end of the crane body, first walking vehicles are arranged at the bottom ends of the supporting frames, installation plates are fixedly installed on the front surfaces of the supporting frames, and first hydraulic telescopic rods are fixedly installed at the bottom ends of the installation plates. When a screw rod rotates, the two ends of the screw rod move to the two sides passing through a movable frame in threaded connection with a third thread groove in a sleeving mode, when the movable frame on the screw rod to move to the two sides, the movable rod drives a second connecting rod to move upwards away from one end of the movable frame, and then the first walking vehicles are driven to integrally move upwards; and when the first walking vehicles move upwards to a certain position, walking wheels at the bottom ends of the first walking vehicles do not fit the ground, second walking vehicles can enable the device to turn and walk, and through the two walking modes, the using flexibility of the device is greatly improved.
本发明公开了一种用于起重机的多形态行走机构,包括起重机本体,所述起重机本体的底端固定安装有支撑架,且支撑架的数量为两个,所述支撑架的底端皆设有第一行走车,所述支撑架的正面皆固定安装有安装板,所述安装板的底端皆固定安装有第一液压伸缩杆。本发明通过当丝杆旋转时,丝杆两端通过第三螺纹槽螺纹套接的活动架向两侧移动,当活动架在丝杆上向两侧移动时,这时活动架带动第二连接杆远离活动架的一端向上移动,进而带动第一行走车整体向上移动,当第一行走车向上移动至一定位置时,第一行走车底端的行走轮不再与地面贴合,这时可通过第二行走车将本装置进行转弯行走,通过两种行走方式,大大提升了本装置的使用时的灵活性。
