Accurate laser-level detection system

Abstract

The invention discloses an accurate laser-level detection system which comprises a rotary laser device, a level detection device, an operating device and a first distance measuring meter, wherein the level detection device is arranged on a front arm of an excavator; a plurality of position signals are detected according to laser levelly emitted by the rotary laser device, and sent to the operating device; and after the operating device receives the signals sent by the level detection device, a position and a deviation angle between the front arm of the excavator and a horizontal plane or between the front arm and a vertical plane are calculated. The accurate laser-level detection system has the benefits that the rotary laser device can provide a level reference plane, and the geometrical layout of the level detection device can provide a position signal for the operating device to utilize a triangle principle to calculate the deviation angle of the front arm of the excavator. The accurate laser-level detection system has the advantages that the level detection device is an array device fixed on the front arm of the excavator, so that the problem that the deviation angle cannot be measured or an error is too large due to vibration is solved, the detection accuracy is ensured, and the service life is prolonged.

Description

Technical field [0001] The invention relates to the field of engineering machinery, in particular to a laser level accurate detection system suitable for excavators. Background technique [0002] Excavators need to master the depth of excavation when leveling the ground. The usual practice is to control the excavator driver's experience, but the number of experienced excavator drivers is very small and cannot meet the demand. [0003] At present, there are also some level detection systems for excavators and other construction machinery. For example, the Chinese invention patent "Laser Level Detection System" with publication number CN1940475 discloses a level detection system that uses laser to determine a reference level. The excavation depth is determined by the level detection device on the forearm of the excavator. However, this detection system still has a shortcoming. Its applicable situation is that the forearm and bucket of the excavator must be perpendicular to the horiz...

Problems solved by technology

However, this detection system still has a shortcoming. The applicable situation is that the forearm and bucket of the excavator must be perpendicular to the horizontal plane, but in actual situations, due to the different ground conditions, the forearm and bucket of the excavator are very There may be an offset, which forms an angle with the vertical direction. At this time, the laser level detection system of this scheme cannot accurately know the actual excavation depth of the excavator.
