The invention belongs to the field of engineering machinery, and particularly relates to a pallet fork device with turnover fork teeth, which comprises a bracket and two fork teeth symmetrically arranged on the bracket, and each fork tooth is provided with a handle assembly and an oil cylinder which are matched with each other; the rear end of the fork tooth is provided with an upper hinge pin hole, a positioning pin hole and a connecting pin hole, and the fork tooth is installed on the bracket through a connecting pin penetrating through the connecting pin hole; the handle assembly comprises a positioning sleeve plate, a connecting sleeve hole and a positioning pin are arranged on the positioning sleeve plate, the positioning sleeve plate is slidably mounted on the connecting pin in a sleeving manner through the connecting sleeve hole, and the positioning pin is slidably mounted in the axial guide hole of the bracket; when the fork teeth are in the working condition of overturning and folding, the positioning pins are arranged in the positioning pin holes, and the positioning pins are prevented from being separated from the positioning pin holes by arranging limiting pieces. By arranging the handle assembly and parts matched with the handle assembly, the fork teeth in the overturning and folding state are positioned and locked, and potential safety hazards caused by accidental falling of the fork teeth are avoided.

    本发明属于工程机械领域,具体涉及一种叉齿可翻转的货叉装置,包括托架和两根对称设置在托架上的叉齿,每一所述叉齿均设有相匹配的把手总成和油缸;叉齿的后端设有上铰接销孔、定位销孔和连接销孔,叉齿由穿过连接销孔的连接销安装在所述托架上;把手总成包括定位套板,定位套板上设有连接套孔和定位销,定位套板通过连接套孔可滑动地套装在连接销上,定位销可滑动地安装在托架的轴向导向孔内;在叉齿处于翻转收起的工况下,所述定位销被配置到定位销孔内,并通过配置限位件防止定位销脱离所述定位销孔。本发明通过配置把手总成以及与把手总成相配合的零部件来对处于翻转收起状态的叉齿进行定位锁紧,避免叉齿出现意外落下造成安全隐患。
