Abstract:
The present application relates to the technical field of construction machines, and in particular to a limiting piece, an anti-roll-over protection structure, and a construction machine. The limiting piece provided in the present application comprises a first limiting part, a connecting part, and a second limiting part which are connected in sequence; the limiting piece is provided with a connecting hole running through the first limiting part, the connecting part, and the second limiting part; both the first limiting part and the second limiting part protrude out of the peripheral surface of the connecting part; the first limiting part is provided with a plurality of side edges that connect the peripheral surface and the surface of the first limiting part; the distance from a point on at least one side edge of the first limiting part to the axis of the connecting hole is variable; the connecting hole is adapted for rotatable connection with a connecting piece; the limiting piece is adapted to move after rotating by a preset angle along with rotation of the connecting piece; the second limiting part is adapted to abut against a first mounting piece. The limiting piece can be switched to an engaged state only by rotating the connecting piece to drive the limiting piece to rotate. The structure is simple, it is convenient to operate, and thus a limiting piece convenient to mount and remove is provided.
