Train cargo transfer forklift

Abstract

The invention discloses a cargo transfer forklift for a train and belongs to cargo transfer forklifts. The cargo transfer forklift can achieve pallet-free transfer and flexible turning. The cargo transfer forklift comprises a cargo pushing mechanism arranged on a forklift body. The cargo pushing mechanism is composed of sliding rails (2) fixed to a fork (9), a rotation mechanism (12) which is fixed to the two sliding rails (2) and connected with a lifting device (1), shear fork expansion brackets (10) hinged to the fork (9), a crank (18) hinged between the two shear fork expansion brackets (10), a cargo pushing oil cylinder (19) hinged between the fork (9) and the crank, a push plate (8) hinged to the front ends of the two shear fork expansion brackets (10), a compression oil cylinder (11) hinged to the fork (9) and a compression fork (5) fixed to the compression oil cylinder. The overall length of the cargo transfer forklift is small, and the cargo transfer forklift can enter a compartment of the train to achieve pallet-free transfer of cargoes.

Description

Technical field [0001] The invention relates to a forklift, in particular to a forklift used for transferring train cargo. Background technique [0002] As we all know, when using forklifts to transfer train goods, the goods are usually loaded and unloaded on the forks through pallets; although simple, convenient and efficient, it is difficult to remove the pallets placed at the bottom of the goods, and the pallets can only be taken with the goods. Transit elsewhere. Not only does it require a large amount of pallet turnover, but it also increases the cost of the goods delivery company; not only that, the pallet will also occupy a certain amount of transportation space and increase the transportation cost. [0003] To this end, the patent document with the publication number "CN202808282U" discloses a utility model patent named "rotary pushing mechanism for forklifts". The rotary pushing mechanism is mainly composed of fork assembly, rotating parts, upper clamping mechanism, and e...

Problems solved by technology

Since the four-link scissor mechanism in the push-out part is arranged horizontally (the scissors are parallel to the fork), the horizontal slide rail in the push-out part is connected with the upper slide rail and the compression cylinder in the upper clamping mechanism (arranged longitudinally). They are perpendicular to each other; therefore, the horizontal slide rail and the upper slide rail or the compression cylinder can only be arranged in a cross-stacked manner (need to occupy a certain space), resulting in an increase in the length of the vehicle, which is not conducive to the forklift entering the train compartment. time turn

In addition, since the cylinder body of the pushing cylinder in the pushing part is set on the four-link scissors mechanism, the movement stroke of the pushing plate is short, the loading capacity of the goods is small, and the transfer efficiency is low

Not only that, the counterweight of traditional forklifts is mostly a solid block structure, and the engine cannot be built into it; therefore, the counterweight will further increase the length of the entire forklift
