Bidirectional dual-regulation fork lifter boom

Abstract

The invention relates to a bidirectional dual-regulation fork lifter boom. The fork lifter boom comprises a rear boom body and a front boom body, wherein the lower end of the rear boom body is arranged on a base bracket; the front boom body is bent; the front end of the long arm of the front boom body is connected with a hook; the upper end of the rear boom body is movably connected with the bentpoint of the front boom body; the base bracket is provided with a cylindrical regulating bracket in which a regulating rod is inserted; the upper end of the regulating rod is movably connected with the lower inside of the rear boom body; regulating holes are correspondingly arranged on the regulating bracket and regulating rod; regulating shafts are arranged in the regulating holes; the upper middle of the rear boom body is connected with the cylinder body of a telescopic oil cylinder; and the extending end of a piston rod of the telescopic oil cylinder is connected with the rear end of the short arm of the front boom body. The boom can realize the movement thereof. The continuous regulation of the lifting point can be realized by regulating the boom through the hydraulic pressure, so theaccuracy of the unloading point of the lifted cargos is ensured. The horizontal regulation of the load center is in the range of 2700 to 4000mm; and the height regulation of the lifting point above the ground is in the range of 250 to 4000mm. The boom has the advantages of rational structure design and convenient assembly and disassembly and maintenance.

Description

technical field [0001] The invention belongs to a lifting mechanism of a forklift, and in particular relates to a boom of the lifting mechanism of a forklift. Background technique [0002] With the continuous expansion of the application field of forklifts, forklifts have been adopted by most users as lifting and transportation equipment. It is a common structural form used by users to hang a boom on the fork frame of the lifting system for lifting goods. The prior art product is that the boom is directly mounted on the fork frame of the forklift. The height of the lifting point of the boom from the ground is fixed. The lifting point can only be adjusted horizontally and intermittently. Each boom is equipped with a hook. Manual assembly is required to adjust the lifting point, which is time-consuming and laborious. Moreover, the lifting point cannot be adjusted after the cargo is lifted, which greatly limits the use of the boom. field. Limited by the existing product struc...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem of large-scale adjustment of the load center distance of the forklift boom and the height of the lifting point from the ground, and realize the problem of lifting and transporting oversized cargo, the invention provides a forklift boom with two-way double adjustment functions
