More Information
Summary:The invention discloses a main engine protection device, which relates to the technical field of engineering machinery, and utilizes a translation driving mechanism to drive a lower support frame to translate and move on a main beam platform, and the lower support frame can be moved to different positions according to needs to realize the protection effect on different positions; the movable protection mechanism moves through walking wheels arranged at the bottom, when the movable protection mechanism moves in place, the movable protection mechanism is guided by a guider, a jacking device drives an upper supporting frame to vertically move, the protective shed is lifted upwards to a proper height, the protection effect can be achieved, and the protective shed is used for shielding stones falling from the upper portion; and when the position is adjusted through translation, the protective shed descends to avoid obstruction. Transverse movement and vertical lifting of the protective shed can be achieved, the sa
