Novel forklift gantry structure with free lifting function

Abstract

The invention relates to the technical field of forklift gantries, and discloses a novel forklift gantry structure with a free lifting function. The novel forklift gantry structure comprises an outergantry, wherein an inner gantry is movably mounted on the front face of the outer gantry; and a guide plate is fixedly mounted at the top of a cross beam of the inner gantry. According to the novel forklift gantry structure with the free lifting function, by arranging the outer gantry, the inner gantry, the guide plate, a lifting oil cylinder, a first chain, a free stroke control block, a second chain, a sliding frame assembly, a pallet fork and a limiting block, after the pallet fork takes goods, the lifting oil cylinder lifts, within the free lifting stroke range, the gantry height, namely the whole forklift height, does not change, but the goods can be lifted by the height twice of the free stroke, under the condition that the overall height of the gantry is not changed, the free lifting distance is increased, and thus a storage vehicle provided with the gantry structure achieves short-distance lifting of the goods and a tray under the condition that the overall height is not changed. The problem of height limitation of a using place is effectively solved.

Description

technical field [0001] The invention relates to the technical field of forklift masts, in particular to a novel forklift mast structure with free lifting. Background technique [0002] According to the requirements of the lifting height of the forklifted goods, the forklift mast can be made into two or more stages. Common ordinary forklifts use two-stage masts, and the common ones are three-section full-free mast, two-section full-free mast and two-section Sectional standard door frame, in which the full-free door frame is usually called the container door frame because it can work in the container. The two-level door frame is composed of the inner door frame and the outer door frame. With the help of the fork frame rollers, it moves up and down along the inner mast to drive the goods to rise or fall. The inner mast is driven up and down by the power cylinder and is also guided by the rollers. There are tilting cylinders on both sides of the rear of the mast, which can make ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a new type of forklift mast structure with free lifting, which has the advantages that the height of the mast, that is, the height of the whole vehicle does not change, but the goods can be lifted at twice the height of the free travel, etc. It solves the problem that the free lifting distance of the traditional forklift mast structure is closely related to the overall height of the mast. If you want to increase its free lifting distance, you can only increase the overall height of the mast.
