Angle-adjustable translational lifting machine

Abstract

The invention discloses an angle-adjustable translational lifting machine. A pair of movable arms I and a pair of connecting rods are hinged to a front frame; the upper ends of the movable arms I andthe connecting rods are hinged to a triangular hinge plate; the movable arms I, the connecting rods, the front frame and the triangular hinge plate form a parallelogram mechanism I; the lower end of amovable arm II is hinged to the hinge point of the movable arms I and the triangular hinge plate; the lower end of a tipping bucket oil cylinder is hinged to the triangular hinge plate; the upper ends of the movable arm II and the tipping bucket oil cylinder are hinged to a machine tool; and when the length of the tipping bucket oil cylinder is equal to that of the movable arm II, the movable armII, the tipping bucket oil cylinder, the machine tool and the triangular hinge plate form a parallelogram hinge mechanism II. The angle-adjustable translational lifting machine adopts a double-parallelogram structure, the angle change of the machine tool is zero in the working process, the translational property is good, and materials are loaded and unloaded more stably and safely; the unloadingheight, the lifting height, the unloading distance and other working sizes can be controlled according to working requirements; the front frame and a rear frame of the machine are hinged in a composite manner, so that the site adaptability is improved; and the machine tool can use a bucket or a fork to realize multiple functions of the machine.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an angle-adjustable translational lifting machine. Background technique [0002] Existing construction machinery with hinged front and rear frames is exampled with a tire loader. The working link system of the loader generally adopts a "Z" type reverse six-bar linkage mechanism to complete the lifting and falling of the boom and the loading and dumping of the equipment. Defects: [0003] 1. When the link mechanism is determined, the working dimensions such as the lifting angle, unloading distance and unloading height of the machine have been determined. When encountering a working condition with a high requirement for unloading material height, the linkage mechanism with a determined unloading height cannot meet the use requirements; Extra distribution of power to the movement of the whole machine affects the working ability of the machine tool; [0004] 2. Whe...

AI Technical Summary

Problems solved by technology

When encountering a working condition with a high requirement for unloading material height, the linkage mechanism with a determined unloading height cannot meet the use requirements; Extra distribution of power to the movement of the whole machine affects the working ability of the machine tool;

[0004] 2. When the boom is lifted, the relative angle between the machine tool and the ground will change, especially when the fork machine tool is used, the angle change when loading and unloading materials may cause the material to fall, so the operator must additionally control the machine tool during work Angle, neither convenient nor safe;

[0005] 3. The boom cylinder of the "Z" type reverse six-bar linkage mechanism is installed horizontally, and the power loss is large when lifting the boom, which affects the lifting speed
