Description
Technical field
The present invention relates to a kind of digger revolving device and method of application thereof, the proving installation and the method for application thereof of particularly a kind of digger revolving speed and rotary braking angle.
Background technology
Hydraulic excavator is a kind of common engineering machinery, has been widely used in every profession and trades such as building, water conservancy.It mainly partly is made up of equipment, slewing equipment, running gear and hydraulic control device etc.; Equipment, slewing equipment, hydraulic control device are called upper body altogether; Running gear is called lower body, and upper body can be along fixedly axis of rotation 360 degree rotations.Speed of gyration is to weigh the important indicator of excavator at the composite move operating efficiency, and speed of gyration is too little, and overall efficiency is very low, and the too big operator of speed of gyration is difficult for controlling and influencing machine life; The braking ability of rotary motor is to influence the accurately important performance of location of operating experience and excavator, and the braking angle is too big, is not easy the location, when entrucking, runs the engineering mine car easily, influence operating efficiency, and it is too little to brake angle, impact too big, driver's easy fatigue.
The control system that Chinese patent CN102071716A relates to a kind of digger revolving speed comprises pressure transducer, engine speed sensor, controller and proportional oil pressure regulating device; Wherein: pressure transducer; The pressure that is used for the working connection hydraulic oil of sensing excavator, and the force value of institute's sensing sent to controller; Engine speed sensor is used for the rotating speed of sensing engine, and tach signal is sent to controller; Controller is electrically connected with pressure transducer and engine speed sensor, is used for confirming the residing operating mode of excavator according to received force value and tach signal, and exports corresponding proportional current according to this operating mode; And proportional oil pressure regulating device; Be electrically connected with controller; Be used for receiving proportional current and regulate the pressure of guide's hydraulic oil of the spool that leads to excavator hydraulic system revolution main valve, thereby regulate speed of gyration through making the spool that turns round main valve have different apertures according to proportional current.
Chinese patent CN101070707B discloses a kind of digger revolving-control method, it is characterized in that: restriction device is set in rotation oil, when turning round control, at first obtains the current job state of excavator; According to current job state the speed of gyration of excavator is regulated, said adjusting realizes through the restriction device that control is arranged in rotation oil again.Realize the digger revolving control system of said method; Comprise rotation oil and hydraulic operation element; On said rotation oil, be provided with restriction device, the control end of said restriction device is connected with the output terminal of controller, includes the excavator operation state detection module in the said controller.This invention can be satisfied the assignment of traffic requirement of most of composite move, under minimum complexity, obtains maximum duty adaptability; Not only improve operator's operation comfort, improved operating efficiency simultaneously, saved fuel consumption.
Important parameter in checking digger revolving performance comprises speed of gyration and rotary braking angle; The braking angle is in order to the braking ability of checking excavator; Present speed of gyration method of testing is just to show the time that steadily revolution 5 is changeed through operator, calculates how many commentaries on classics of per minute then.
The rotary braking measurement of angle is adopted earlier at digger revolving supporting gear ring and the following vehicle frame same position paper of taping; Eyed to the front by operator then and fix this position earlier, turn round then, adhesive tape can be divided into two parts up and down rotating the time; After treating the gyrostabilized platform velocity-stabilization; Normally continuous three change more than, the direction of fixing at the operator just now again braking of loosing one's grip, again test up and down the circular arc of adhesive tape apart from calculating the rotary braking angle.
The maximum shortcoming of this method of testing is that error is bigger, and driver's judgement is depended in braking opportunity fully, is easy to generate subjective error.
Summary of the invention
In view of the above problems, the objective of the invention is to overcome the shortcoming of prior art, a kind of hydraulic excavator speed of gyration and rotary braking angle measurement device and method of application thereof are provided.
