Real-time test method of loader shovel loading operation resistance based on position calculation

Abstract

The invention discloses a real-time test method for loader shovel loading operation resistance based on position calculation, which comprises the following steps: taking point B as the coordinate origin and establishing a fixed coordinate system XOY as the X direction parallel to the ground; The displacement distance of the piston rod of the boom cylinder at any time node during the bucket operation process, and the length L of the boom cylinder at this time node is obtained Qa ;Measure the displacement distance of the piston rod of the bucket cylinder at the time node of the bucket operation, and obtain the length L of the bucket cylinder at this time node Pf ;Determine the force of the boom pin shaft at the connection between the left and right booms of the loader and the bucket at this time node of the bucket operation; measure the loader's rocker arm passing through the connection between the connecting rod / bracket and the bucket The force of the upper pin shaft at this time node of the bucket operation. The real-time resistance of the loader operation at this time node is calculated based on the geometry. The invention is accurate, convenient and rapid in testing, and well overcomes the problem of inaccurate testing in the prior art.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a real-time testing method for loader shovel loading operation resistance based on position calculation. Background technique [0002] Loader is a kind of earthwork construction machinery widely used in highway, railway, construction, hydropower, port, mine and other construction projects. It is mainly used for shoveling bulk materials such as soil, sand, lime, coal, etc. , hard soil, etc. for light shoveling and digging operations. It can also carry out bulldozing, lifting and loading and unloading of other materials such as wood by changing different auxiliary working devices. In the construction of roads, especially high-grade highways, loaders are used for filling and excavation of roadbed engineering, asphalt mixture and aggregate and loading of cement concrete yards. Still can undertake pushing ground of carry soil, strickle and drawing in addition the exerc...
