Detailed description of the invention
Fig. 1 is the digging of the test method of the digger operating device and engine load of first embodiment according to the present invention
Pick machine structural schematic diagram.
Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention
Shield range is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
As shown in Figure 1, the test method of digger operating device according to the preferred embodiment of the invention and engine load
The following steps are included:
Firstly, being respectively arranged scraper bowl angular transducer 2, dipper on the scraper bowl 1 of excavator, dipper 3, large arm 4, turntable 8
Angle sensor 4, big arm angle sensor 5 and turntable angular transducer 7, the attitude detection of each component when realizing work.
The actual working state of excavator is divided into excavation -- band load promotion -- band load rotation -- discharging -- sky according to movement
Carrying rotation -- zero load declines, in total six kinds of working conditions.
Secondly, determining scraper bowl posture using scraper bowl angular transducer 2, and pass through dipper angle sensor 4, large arm angle sensor
Device 5, turntable angular transducer 7 determine the operating position of scraper bowl；
Wherein, scraper bowl posture and method for determining position, scraper bowl posture are directly obtained by scraper bowl angular transducer 2, scraper bowl
Posture --- -- refer to confirmation scraper bowl be just started to dig, dig to native (or other materials), dig it is full, receive the various work such as bucket when position
Situation.At this time it is only necessary to know that dipper 3, large arm 6 straight pin linear distance, point AB, the distance between point BC and dipper
The angle of the angle of angle sensor 4, big arm angle sensor 5, can be with using the sine or the cosine law of triangle
