The invention relates to a telescopic hooking pallet fork with unequal-length fork plates, which comprises a hooking fork assembly, a transmission assembly, a driving mechanism and a clamping mechanism, the hooking fork assembly comprises an outer fork, a middle fork, an inner fork and a linkage synchronous belt, and the middle fork is arranged on the inner side of the outer fork and is in sliding connection with the outer fork; the inner fork is arranged on the inner side of the middle fork and is in sliding connection with the middle fork through an inner fork sliding rail assembly, the middle fork is driven by the driving mechanism to move, the driving mechanism transmits torque through a transmission assembly arranged on the lower side of the middle fork, one end of the linkage synchronous belt is fixedly arranged at the rear end of the outer fork, and the other end of the linkage synchronous belt is fixedly connected with the middle fork. The clamping mechanism comprises a first synchronous belt and a third synchronous belt, one end of the outer fork is fixed to the first synchronous belt, and the other end of the outer fork is fixed to the third synchronous belt. The length of the inner fork of the hook fork assembly is shortened, and the extending distance of the inner fork is larger than the length of the inner fork, so that the deflection of the pallet fork after extending is reduced, and the weight of the pallet fork is reduced.
本发明涉及一种不等长叉板的伸缩勾取货叉,包括勾叉组件、传动组件、驱动机构和夹紧机构,所述勾叉组件包括外叉、中叉、内叉和联动同步带,其中中叉设于外叉内侧并与外叉滑动连接,内叉设于中叉内侧并通过内叉滑轨组件与中叉滑动连接,所述中叉通过所述驱动机构驱动移动,且所述驱动机构通过设于所述中叉下侧的传动组件传递力矩,所述联动同步带一端固设于所述外叉后端,另一端穿过并绕过所述中叉前端后固设于所述内叉后端,所述夹紧机构包括第一同步带和第三同步带,且所述外叉一端与第一同步带固定、另一端与第三同步带固定。本发明勾叉组件的内叉长度缩短,且内叉可伸出距离大于内叉自身长度,从而降低了货叉伸出后的挠度,减轻货叉重量。
