Four-range-of-motion electrical-hydraulic mechanism type wood forklift with multi-unit linear driving function

Abstract

A four-range-of-motion electrical-hydraulic mechanism type wood forklift with a multi-unit linear driving function comprises a multi-unit linear driving mechanism, a movable arm lifting mechanism, a fork bucket control mechanism and the like. The multi-unit linear driving mechanism is driven by a multi-set linear driver, achieves high-power and high-torque power output through a crankshaft and meets the power requirement of high-load operation of the wood forklift. A hydraulic cylinder is applied to the configuration design of the wood forklift as a connection rod on the basis of the Pascal principle, the problem that in the prior art, stress on two driving chains for lifting a movable arm is unbalanced is effectively solved through introduction of a hydraulic element, and the bearing stability is improved. The wood forklift not only has the characteristics of being high in transmission efficiency, high in response speed, high in motion precision, good in controllability, capable of saving energy, environmentally friendly and the like as a controllable mechanism, but also has better bearing performance and shock resistance through introduction of the multi-unit connection rod driving mechanism and the hydraulic element, can achieve the overload protection function easily and has great engineering application prospects and development potential.

Description

technical field [0001] The invention relates to the field of forklifts, in particular to a multi-unit linear drive four-degree activity electro-hydraulic mechanism type forklift. Background technique [0002] The forklift is a key equipment widely used in forestry, agriculture, construction and other related fields for handling, loading and unloading of wood, sugar cane, columnar building materials, etc. Traditional hydraulic forklifts are designed and developed on the basis of traditional hydraulic loaders, which have disadvantages such as high energy consumption, high noise, serious exhaust emissions, and low level of intelligence. The controllable mechanism is the product of the combination of traditional mechanism and electronic technology. The "Numerical Control Generation" equipment innovation project carried out in recent years has brought opportunities for the upgrading of traditional production machinery technology. Aiming at the shortcomings of hydraulic forklifts,...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems existing in the prior art, and to provide a multi-unit linear drive four-degree-of-motion electro-hydraulic mechanism type forklift. This kind of forklift uses controllable mechanism technology and adopts a new configuration design to make it both It has the advantages of high intelligence, good flexibility, and high transmission efficiency of the existing controllable mechanism loading and unloading machinery, and at the same time solves the problem of poor power performance, weak load capacity, poor stability of the boom lifting mechanism, and lack of effective overload for the controllable mechanism loading and unloading machinery Engineering problems such as protection and vibration absorption means, effectively overcome the problems of low mechanical efficiency, serious noise pollution, and low level of intelligence in traditional hydraulic forklifts, so that the forklift has better dynamic performance and load-bearing stability. At the same time, it has strong anti-vibration ability and overload protection performance
