The invention relates to the field of engineering machinery, and discloses a chassis limiting device, an engineering machinery chassis and engineering machine.The chassis limiting device comprises a body connecting piece, a first limiting piece and a second limiting piece, and the body connecting piece is used for being fixedly connected with a chassis body of the chassis; the first limiting piece and the second limiting piece are used for being fixedly connected with supports on the two transverse sides of the chassis body correspondingly, oppositely arranged on the two sides, in the first direction, of the body connecting piece and movably connected with the body connecting piece correspondingly. The body connecting piece can independently or synchronously move in the first direction relative to the body connecting piece. According to the chassis limiting device, the supports on the two transverse sides of the chassis body are supported and limited, so that the supports on the two transverse sides of the chassis body can be kept parallel in the transverse direction of the chassis body in the relative movement process, and the reliability of the engineering machinery chassis is effectively improved.

    本发明涉及工程机械领域,公开了一种底盘限位装置、工程机械底盘以及工程机械,底盘限位装置包括主体连接件、第一限位件以及第二限位件,主体连接件用于与底盘的底盘主体固定连接;第一限位件和第二限位件分别用于与底盘主体横向两侧的支架固定连接,第一限位件和第二限位件相对设置于主体连接件在第一方向上的两侧,第一限位件和第二限位件分别与主体连接件活动连接,以能够单独或同步地相对主体连接件沿第一方向移动。本发明的底盘限位装置对底盘主体横向两侧的支架起到支撑和限位的作用,使得底盘主体横向两侧的支架在相对移动的过程中在底盘主体的横向上能够保持平行,有效提高工程机械底盘的可靠性。
