Juvenile frame with firm structure

Abstract

The utility model relates to the technical field of excavators and provides a firm-structure lifting frame which comprises a frame body, a bucket lug and a horse puller are integrally formed at the two ends of the frame body, a reinforcing structure used for reinforcing stability is arranged between the bucket lug and the horse puller, supporting plates are fixed to the upper side face and the lower side face of the frame body, and the supporting plates are arranged on the upper side face and the lower side face of the frame body. The reinforcing structure comprises three first reinforcing ribs, one ends of the three first reinforcing ribs are fixed to the horse puller, and the other ends of the three first reinforcing ribs are all fixed to the supporting plate. According to the lifting frame with the firm structure, the first reinforcing rib, the second reinforcing rib and the third reinforcing rib are arranged, so that the first reinforcing rib, the second reinforcing rib and the third reinforcing rib can form a stable triangular structure, a closed structure cannot be formed, and the situation that dust and water are accumulated is avoided; and the strength of the frame body can be greatly enhanced while the stability of the frame body can be maintained, so that the lifting frame with a firm structure is constructed.
