Forklift device with high degree of freedom

Abstract

The invention discloses a forklift device with a high degree of freedom. The forklift device with the high degree of freedom comprises a car body and a lifting mechanism for up-and-down loading and unloading cargoes, wherein a steering mechanism for supporting, moving and steering the car body is arranged on the lower part of the car body; a rotation frame mechanism is connected between the car body and the lifting mechanism and is fixedly connected with the lifting mechanism; the rotating frame mechanism is rotatably connected with the car body; the lifting mechanism rotates around the car body through the rotating frame mechanism; a groove matched with the car body is formed in the rotation frame mechanism; at least one roller is arranged on each of two opposite side surfaces of the groove; annular rail grooves are formed in the opposite upper and lower surfaces of the car body; the rollers can be rotatably arranged in the annular rail grooves; and the rotation frame mechanism rotates relative to the annular rail grooves through the rollers. Through the cooperation of the lifting mechanism, the steering mechanism and the rotation frame mechanism, the adjustment of a forklift in multiple degrees of freedom is realized, and the forklift is good in flexibility, high in obstacle avoidance capacity, and capable of meeting the requirement of a complicated carrying environment for modern logistics storage.

Description

technical field [0001] The invention relates to the technical field of forklift handling, in particular to a high-degree-of-freedom forklift device. Background technique [0002] Forklifts are widely used mobile loading and unloading machinery, and are a kind of material handling machinery. The forklift is composed of a special loading and unloading working device installed on a trackless wheeled chassis equipped with a power unit. As a mobile handling equipment for loading and unloading and short-distance transportation, forklifts are not only used in the national infrastructure industry, but also widely used in ports, stations, freight yards, warehouses, workshops, oil fields and airports. In addition, forklifts can enter the cabin and Operation in containers, but also widely used in the military sector. However, the front end of a general forklift is provided with a mast, and the cargo fork is movable up and down on the mast, and the cargo fork is usually driven by a ch...

AI Technical Summary

Problems solved by technology

Except some manual pallet forklifts are driven by manpower, others mostly use hydraulic drive. However, with the development of modern logistics and the continuous improvement of handling technology requirements, the existing storage forklifts have exposed many technical problems. First of all, the existing storage forklifts Most of the working devices are two-degree-of-freedom actuators. The forks can only move up and down except that they can be tilted at a small angle. The flexibility is poor and the ability to avoid obstacles is weak. It is difficult to meet the complex handling environment of modern logistics and warehousing.

In addition, the working devices of existing storage forklifts mostly use hydraulic systems to lift the forks, which has problems such as high power, high energy consumption, and poor reliability.
