Abstract

The invention discloses a forklift pallet fork distance adjusting assembly which comprises an installation frame, a pallet fork installation frame and a pallet fork. An output shaft of an oil hydraulic cylinder on the installation frame is fixedly connected with the pallet fork installation frame. An upper beam of the installation frame and a lower beam of the installation frame are provided with two groove-shaped rails which are opposite to each other. Idler wheels arranged on the pallet fork installation frame are clamped into the groove-shaped rails to enable the pallet fork installation frame to be located between the upper beam of the installation frame and the lower beam of the installation frame, and the pallet fork installation frame can transversely move relative to the installation frame. An L-shaped groove-shaped rail is arranged at the top end of the upper beam of the installation frame. Hooks are arranged on the pallet fork, are connected to the L-shaped groove-shaped rail in a lapping joint mode, and can slide inside the L-shaped groove-shaped rail. The transverse width of pallet fork installation frame is larger than that of the pallet fork. Limiting plates are arranged on the two sides of the pallet fork on the pallet fork installation frame. The pallet fork installation frame pushes the pallet fork to move transversely through the limiting plates. The forklift pallet fork distance adjusting assembly has the advantages that the distance of two pallet forks can be adjusted synchronously, small front overhang of a whole vehicle is ensured, and forklift operation intelligentization is facilitated.

Description

Fork of forklift truck pitch adjusting structure assembly
Technical field
The present invention relates to fork truck, is fork of forklift truck pitch adjusting structure assembly specifically.
Background technology
Fork truck is industrial transportation vehicle, in the logistics carrying, plays the part of more and more important role.Its gauge size of the shelf of bearing product disunity, can adapt to this variation for making pallet fork, just requires the distance between two pallet forks to adjust.In conventional art, be mainly to rely on to pull manually the purpose that pallet fork reaches roll adjustment, this method not only labor strength is large, and roll adjustment efficiency is not high, need manual repeatedly debugging just can complete, for this reason, have the roll adjustment that the structure moved with oil cylinder pushing two pallet forks realizes pallet fork in prior art, but the output shaft of oil cylinder directly is connected on pallet fork, the oil cylinder output shaft is an application force to the application force of pallet fork, consider the needs of complete machine compactedness etc., two oil cylinders are top-bottom layout, this just make the oil cylinder output shaft to the point of action of pallet fork not on same axis of pitch, even make two oil cylinder power outputs identical, but two moments that are applied on pallet fork are not identical, thereby the resistance difference be subject to during the pallet fork motion, finally cause the two pallet fork roll adjustments can not be synchronous, its roll adjustment low precision, also have in prior art pallet fork is arranged on the pallet fork erecting frame, the oil cylinder output shaft is connected and indirectly promotes the structure that pallet fork moves with the pallet fork erecting frame, but in this kind of structure, the pallet fork erecting frame is suspended on the place ahead of erecting frame, this has increased the complete machine front overhang greatly, thereby has reduced the hoisting capacity of pallet fork.Therefore, the pallet fork pitch adjusting structure in conventional art need further improve and promote.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of fork of forklift truck pitch adjusting structure assembly, it has the characteristics such as two pallet fork roll adjustments are synchronous, fork truck complete machine front overhang is little.
The technical solution adopted for the present invention to solve the technical problems is:
