The invention belongs to the field of engineering machinery, and particularly relates to engineering machinery and supporting legs thereof. The sliding groove frame is in sliding fit with the ball head and the sliding plate, the supporting foot disc base is fixedly and rotationally connected with the sliding groove frame through the ball socket base, and the limiting frame is used for limiting the supporting foot disc base. The ball socket base is fixedly and rotationally connected with the sliding groove frame, so that the supporting foot plate can be inclined conveniently, and the problem that the departure angle and the approach angle of a crane vehicle are greatly limited due to the fact that the supporting foot plate cannot be inclined is solved. The sliding groove frame and the ball socket base can rotate relatively, a supporting face with a large inclination angle can be stably supported, equipment cannot be damaged, the adaptability of the supporting foot disc is improved, and the service life of the supporting foot disc is prolonged. And the ball head always moves in the sliding groove, so that the situation that the ball head is separated from the slide way to cause falling of the supporting foot disc is avoided.

    本发明属于工程机械领域,尤其涉及一种工程机械及其支腿。本发明滑槽架与球头和滑动板均滑动配合,支脚盘底座通过球窝底座与滑槽架可固定式转动连接,限位架用于对支脚盘底座进行限位。通过球窝底座与滑槽架可固定式转动连接,可方便实现支脚盘倾斜,解决了支脚盘不能倾斜而大大限制了起重机车辆离去角、接近角的问题。本申请中滑槽架与球窝底座可相对转动,对于倾斜角度大的支撑面也可稳定支撑且不会损坏设备,提高了支脚盘的适应性和使用寿命。球头始终在滑移槽内移动,避免了球头脱离滑道导致支脚盘掉落的情况。
