The invention discloses a forklift mask assembly in the field of forklift masks. The forklift mask assembly comprises an inner mask, an outer mask, a first roller assembly and a second roller assembly, wherein the first roller assembly and the second roller assembly are arranged between first channel steel of the outer mask and second channel steel of the inner mask, a wing plate of the fixed endof the first channel steel and the inner side surface of a web plate of the first channel steel form a first bending surface, the outer side surface of a web plate of the second channel steel is provided with a protrusion, and the protrusion is close to a wing plate of the fixed end of the second channel steel and forms a second bending surface with the outer side surface of the web plate of the second channel steel; and the first roller assembly is fixed at the upper end of the inner side surface of the web plate of the first channel steel, and the second roller assembly is fixed at the lowerend of the outer side surface of the web plate of the second channel steel; and the cylindrical surface of a roller of the first roller assembly is in contact with the second bending surface, and thecylindrical surface of a roller of the second roller assembly is in contact with the first bending surface. According to the forklift mask assembly, the stress points of the rollers are adjusted, sothat the stress deformation of the outer mask and the inner mask is reduced, the structural stability of a forklift is improved, the safety performance is improved, and the service life is prolonged.
本发明公开了叉车门架领域的一种叉车门架总成,包括内门架、外门架,设置在外门架的第一槽钢与内门架的第二槽钢之间的第一滚轮组件与第二滚轮组件;第一槽钢的固定端翼板与其腹板内侧面构成第一弯折面;第二槽钢的腹板外侧面上设有凸起,凸起靠近第二槽钢的固定端翼板,并与第二槽钢的腹板外侧面构成第二弯折面;第一滚轮组件固定在第一槽钢的腹板内侧面的上端部,第二滚轮组件固定在第二槽钢的腹板外侧面的下端部;第一滚轮组件的滚轮圆柱面与第二弯折面相接触,第二滚轮组件的滚轮圆柱面与第一弯折面相接触。本发明调整了滚轮受力点,减少外门架、内门架的受力变形,提高了叉车的结构稳定性,提高了安全性能和使用寿命。
