Embodiment Construction

[0025] The specific implementation will be described below in conjunction with the accompanying drawings.

[0026]The working device of the loader is driven by hydraulic pressure. In the hydraulic drive control system of the working device of the loader, the hydraulic pump outputs hydraulic oil through the working device to control the multi-way valve to drive the working device. The multi-way valve is a solenoid valve, which is connected with the controller to control The device controls the multi-way valve to control the drive oil circuit of the working device through the output control current, so that the working device can show the desired action and action speed. The control handle is an electric control handle, which is connected with the controller and used for inputting the operation intention of the operator.

[0027] The loader is also equipped with sensors for detecting the attitude of the working device and connected to the controller. These sensors include a boom...

Abstract

The invention relates to a method for acquiring location parameter data of a working device. In order to solve the problems of time and effort waste, and poor accuracy, the invention provides the method for acquiring the location parameter data of the working device of the loader. The location parameter data of the working device comprise shoveling and loading initial position reset position parameter data, shovel loader retracting limiting position parameter data, shovel loader releasing limiting position parameter data and movable arm lifting limiting position parameter data. The method for acquiring the location parameter data comprises the steps of automatically controlling the working device of the loader through a control program and accomplishing a specific action group I, a specific action group II and a specific action group III; and in the process of accomplishing the specific actions, recording a shovel loader angle and a movable arm angle, using as corresponding location parameters, and storing. The method for acquiring the location parameter data of the working device provided by the invention is simple to operate, and a calibration process can be automatically accomplished, so that the working efficiency can be greatly improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to a loader, more specifically, to a method for acquiring position parameter data of a working device of the loader. Background technique [0002] With the development of loader technology, while people's demand for loader operation functions is increasing, people also have higher and higher requirements for handling comfort. To achieve these goals, loaders are usually equipped with some automatic control operations, such as automatic shovel loading , or perform automatic limit buffering at a certain position during the shovel loading process. To carry out these automatic control operations, it is necessary to set the posture and position of the working device of the loader. For example, after the shovel is loaded and unloaded, the bucket is automatically leveled to the ground. It is necessary to set the angle of the boom relative to the bucket at different positions, so that When the boom is at a certain position, adjust the ang...
