Design method of high-position unloading loading machine

Abstract

The invention discloses a design method of a high-position unloading loading machine. The design method is characterized in that firstly a new high-position unloading height of a complete machine is determined according to the material unloading state of a bucket, and the perpendicular height of a hinged joint of a movable arm and the bucket is worked out according to the new high-position unloading height; the hinged joint of the movable arm and the bucket is adjusted to a new perpendicular height; torque values of all driven parts are worked out; a torque value of a driving part of a movablearm oil cylinder is worked out; a moment arm of the movable arm oil cylinder is reversely calculated according to the driving part torque value needing to be generated by the movable arm oil cylinder; a maximum installation distance of the movable arm oil cylinder is determined; the down-digging depth of the bucket is ensured so that digging and loading operation can be conveniently conducted bythe bucket on the uneven ground surface; and a minimum installation distance of the movable arm oil cylinder is determined, further the travel of the movable arm oil cylinder is determined, and finally parameters of the movable arm oil cylinder are determined. According to the design method, the hinged joint of the movable arm oil cylinder and the movable arm is optimized and the installation distances and the travel of the movable arm oil cylinder are recalculated according to the relation between driving part torque and driven part torque, and the purpose of high-position unloading is achieved.

Description

technical field [0001] The invention relates to a design method of a high-dump loader, which belongs to the technical field of engineering machinery. Background technique [0002] The loader is a multifunctional construction machine, which is mainly equipped with a bucket at the front end for earth and rock shoveling operations. In order to meet the needs of some special working conditions, it is often necessary to develop and design high-loading loaders on the basis of conventional loader models. The usual design method is to lengthen the boom and tie rods, and re-select thicker levers to ensure the lifting force. Arm oil cylinder, in order to ensure the stability of the whole machine after increasing the quality of the counterweight. Although this method can meet the needs of use to a certain extent, there is a need to redesign and verify the hinge point trajectory between the boom, rocker, tie rod, and bucket, which is time-consuming and laborious, and the parts are not ...

AI Technical Summary

Problems solved by technology

[0003] The problem to be solved by the present invention is: the existing high-load unloading machine needs to lengthen the boom and tie rod, and use a thicker boom cylinder to increase the quality of the rear counterweight, thereby causing the length of the whole machine to increase, the center of gravity of the whole machine to move forward, and the weight of the whole machine to increase. Decreased stability, increased turning radius, poor maneuverability, increased fuel consumption, etc.
