The hydraulic pipeline system of the attachment based on the secondary mast structure of the forklift

Abstract

The invention provides a hydraulic pipeline system of an accessory based on a forklift double mast structure. The hydraulic pipeline system comprises an outer mast, an inner mast, a pulley block and two sets of hydraulic rubber pipes, two ends of the hydraulic rubber pipes are connected with a multi-way valve and the accessory respectively to form two hydraulic oil paths, a left outer guide rail and a right outer guide rail are symmetrically arranged on two side columns at the front end of the outer mast, and a left inner guide rail and a right inner guide rail are arranged on a middle cross beam at the front end of the inner mast in a bilateral symmetry mode. Each hydraulic rubber pipe set is formed by connecting two rubber pipes through a four-way joint, the upper portions of the first rubber pipes are in an n shape and are fixedly arranged at the top ends of the outer guide rails through pipe clamps, and the lower portions of the first rubber pipes are arranged in guide grooves of the inner guide rails. The lower end of the second rubber pipe of the first hydraulic rubber pipe set is connected with the accessory through a lower left four-way joint, the upper end of the second rubber pipe of the first hydraulic rubber pipe set is connected with the rear end of the first rubber pipe through an upper left four-way joint after penetrating through the pulley block, and the front ends of the first rubber pipes are connected with the multi-way valve. The hydraulic pipeline system is not limited by the number of valve sheets of the multi-way valve and the height of the masts, and is suitable for masts of the height of the same configuration forklift series, and efficiency is improved.

Description

technical field [0001] The invention relates to a hydraulic system of a forklift, in particular to a hydraulic pipeline system of attachments based on the secondary mast structure of the forklift. Background technique [0002] Forklifts are generally equipped with attachments, which diversify the functions of the forklift, make the entire operation process more mechanized and reduce labor intensity; and the power of attachments that can achieve multiple functions requires a hydraulic pipeline system to drive its actions. At present, for the forklift with two-level full-free mast and attachments, there are many layouts of high-pressure pipelines from the multi-way valve to the four-way joint of the fork frame. Generally, the height of the mast of the forklift is 2-6 meters. The lifting height is designed according to actual needs, and the layout of the hydraulic pipeline system is set differently according to the lifting height of the forklift mast: when the lifting height is...

AI Technical Summary

Problems solved by technology

In addition, since the attachment hydraulic pipeline is an auxiliary pipeline of the forklift hydraulic system, its layout depends on the space of the mast structure, which seriously affects the driver's vision and affects the appearance of the forklift.
