Abstract

The invention discloses a scraper pan positioning device and method for a backhoe excavator. The scraper pan positioning device comprises a positioning device, a direction measuring device, a scraper pan position measuring device and a calculating device, wherein the positioning device is used for receiving a spatial position, under a certain ground reference frame, of a rotary machine seat of the excavator; the direction measuring device is used for measuring angle information of a course angle, a pitch angle and a roll angle of the rotary machine seat of the excavator; the scraper pan position measuring device is used for measuring spatial position information of a scraper pan of the backhoe excavator; the calculating device is used for calculating the longitude, latitude and elevation of the scraper pan according to the spatial position information, the spatial position, under the certain ground reference frame, of the rotary machine seat of the excavator and the angle information of the course angle, the pitch angle and the roll angle. In conclusion, by utilizing the scraper pan positioning device and calculation method for the backhoe excavator, the operation of the backhoe excavator is guided through two different operation procedures. According to the scraper pan positioning device and method for actively guiding, the accurate operation quantity measurement is provided for an operator and operation management department of the backhoe excavator, and the state, operation degree and filling-excavation amounts of an operation area can be calculated.

Description

technical field [0001] The invention relates to the technical field of backhoe excavators, in particular to a bucket positioning device and method for backhoe excavators. Background technique [0002] With the rapid development of my country's economy, backhoe excavators are required for engineering construction and mineral mining. When backhoe excavators are used for large-scale operations, there is often a lack of information management means and functional guiding devices, resulting in slow construction or mining speeds, and the inability to achieve precise management and fixed mining. At present, there are many bus navigation systems and intelligent transportation systems, but there is a lack of guidance devices and supporting methods for construction vehicles, especially backhoe excavators. At present, the existing backhoe positioning system uses fan-shaped laser measurement, but it can only be applied to relatively flat surface environments and general vehicle positio...
