Pull-push device on pallet fork of forklift loader

Abstract

The invention provides a pull-push device on a pallet fork of a forklift loader, comprising the pallet fork. The pull-push device is characterized in that the pallet fork is provided with an installing frame, and a scissor mechanism, pull-push oil cylinders and a pull-push frame are arranged on the pallet fork; one end of the scissor mechanism is connected with the installing frame on the pallet fork, and the other end of the scissor mechanism is connected with the pull-push frame; and a cylinder barrel of each pull-push oil cylinder is connected with the installing frame of the pallet fork, and a piston rod of each pull-push oil cylinder is connected with the pull-push frame by a connecting piece. The scissor mechanism consists of two sets of symmetrical telescopic pieces, and each set of the telescopic piece is formed by the means that a back inner rod, a back outer rod, a front inner rod and a front outer rod are movably connected with one another by pin shafts; and every two pull-push oil cylinders are in parallel with each other. The pull-push device has the beneficial effects of being stable and powerful in pushing and pulling, quick and exact in stacking, safe, and reliable, thereby being very practical in the assembling and disassembling of container cargos and the stacking of large-tonnage cargos.

Description

technical field [0001] The invention relates to a push-pull device on a fork of a forklift truck. Background technique [0002] When the existing forklift truck is unloading and stacking operations, the two fork legs on the fork must rely on the two supporting holes left by the pallet to fork the goods on the pallet and stack them neatly. For large-tonnage stone blocks, without pallets, it is difficult to fork and stack stone blocks with the prongs on the fork. Contents of the invention [0003] The purpose of the present invention is to provide a push-pull device on the fork of a forklift truck. When encountering large-tonnage goods, the goods only need to be fixed on the push-pull frame on the fork, and the push-pull frame can pull the goods to the goods. On the fork, when stacking, the push-pull frame is pushed out, and the goods are stacked neatly, which is very convenient, without the help of the two supporting holes on the pallet. [0004] The present inven...
