Hydraulic combining system for pusher and side shifter of forklift

Abstract

The invention provides a hydraulic combining system for a pusher and a side shifter of a forklift. The hydraulic combining system for the pusher and the side shifter of the forklift comprises the pusher, a multi-way valve and two high-pressure hydraulic oil ways, wherein each of the two high-pressure hydraulic oil ways comprises a first high-pressure rubber hose, a second high-pressure rubber hose, a third high-pressure rubber hose and a fourth high-pressure rubber hose; an integrated side shifter comprising a frame and a side shifting oil cylinder is connected to the front end of the expeller; a second four-way connector and a third four-way connector are arranged at the front end of the integrated side shifter; a first four-way connector and a fourth four-way connector are arranged in a line on a lower cross beam of the frame; an oil way formed by the connection of the first high-pressure rubber hose and the fourth high-pressure rubber hose is a hydraulic oil way that drives the integrated side shifter to laterally shift left and right; another oil way formed by the connection of the second high-pressure rubber hose and the third high-pressure rubber hose is the hydraulic oil way that drives the pusher to push out and take back. With the adoption of the hydraulic combining system for the pusher and the side shifter of the forklift, the arrangement of pipelines is simplified, the visual range of a driver is expanded, device parts are decreased, the loss-of-load distance is reduced, and the bearing capability of the forklift is improved.

Description

technical field [0001] The invention relates to a forklift hydraulic system, in particular to a combined hydraulic system for a forklift pusher and a side shifter. [0002] Background technique [0003] Forklifts are mainly used in tobacco, food, textile, electronics, printing and other industries for loading and unloading, stacking and short-distance transportation of palletized goods. It is especially suitable for narrow lanes and narrow spaces. Operation. In order to facilitate the forklifting and stacking of goods, and improve the flexibility and handling efficiency of the forklift, the mast side shifter is equipped on the forklift mast. The side shifter can allow the goods on the fork to move laterally for a certain distance, especially It is suitable for various working occasions of forklift handling and stacking. However, because the existing side shifter is mounted on the fork frame, it can only realize the left and right lateral side shifting function of the good...

AI Technical Summary

Problems solved by technology

In order to arrange the pipeline reasonably, the four-way joint is installed on the crossbeam of the fork frame. The elbow at the rubber hose and the four-way joint will occupy the upper space of the oil port, the layout is complicated, the appearance quality is poor, and the pipeline connection is messy after assembly. ;In addition, when the device is working, the whole device is lifted to a certain height, and the messy pipes just block the driver's vision, affecting the driver's normal work
