Abstract
The invention discloses a control device of an excavator, in particular to a rollover protection system which is used to prevent the rollover of the excavator which is caused by improper operation or false operation. The rollover protection system comprises a programmable controller, a double cross-pin inclination sensor, a latching-concealing switch, a digital display and a hydraulic oil source valve. An inclination protection system is a relative individual embedded unit through adopting a modularization design method which combines the open-loop control and a PLC controller programming, which provides negative safeguard for the whole device. The system can be modified according to the different requirements of controlled objects, and the suitability is strong. The device can be well compatible with various electric control systems, and is embedded in the systems, which lays technical foundation for the updating of engineering machinery, and has excellent application popularization prospect.
Description
Technical field
The present invention discloses a kind of excavator control device.Specifically, be to be used for preventing causing the rollover protection system that excavator is tumbled because of misoperation or faulty operation.
Background technology
Development along with engineering machinery; require more and more higher to its security protection of controlling; especially in danger zone operation and walking; operation excavator in mountain region is at the wheel leg mating type chassis of mountain region condition; can on the abrupt slope of 45 degree, walk and operation, but must provide enough safeguard protections to driver and crew.As not protecting, the excavator overthrow accident takes place easily, driver and crew's personal safety is difficult to ensure.
The utility model content
The problem to be solved in the present invention provides a kind of rollover protection system.Adopt rollover protection system, can avoid the generation of excavator overthrow accident, can guarantee driver and crew's personal safety.
For addressing the above problem, take following scheme:
Rollover protection system of the present invention is made up of programmable logic controller, double cruciform shaft obliquity sensor, releasing locking switch, digital display and hydraulic oil source valve; adopt that open loop control and PLC controller programming combine the modularized design means; make that the inclination angle protection system is a relatively independent embedded unit, for complete machine provides the passive security protection.
Adopt such scheme.Have the following advantages:
Rollover protection system is to be applied in the anti-tipping protection control system of the cover of one on the mountain region operation excavator; significant feature is: operation excavator in mountain region is walked on mountain region or abrupt slope and during operation; the angle of slope of the operating platform of control mountain region excavator prevents that misoperation or faulty operation from causing tumbling of excavator.Structurally be rollover protection system mainly by the digital display in the double cruciform shaft obliquity sensor that is installed in wheelhouse flat, the driver's cabin, remove locking switch and programmable logic controller and the software program independently write is formed.Adopting open-loop control system and PLC controller programming way of combining in the design of rollover protection system, is an independently embedded ECU.Obliquity sensor offers programmable logic controller after gathering dip angle signal, after inner calculation process, carries out the order of reporting to the police and pinning dangerous play, makes the inclination angle of excavator all the time in safe range, prevents overthrow accident.
Description of drawings
Accompanying drawing is a rollover protection system schematic diagram of the present utility model.
The specific embodiment
As shown in drawings; rollover protection system of the present utility model is made up of programmable logic controller, double cruciform shaft obliquity sensor, releasing locking switch, digital display and hydraulic oil source valve; adopt that open loop control and PLC controller programming combine the modularized design means; make that the inclination angle protection system is a relatively independent embedded unit, for complete machine provides the passive security protection.
A threshold value and a dangerous values in the program of the controller of writing, have been set, after the double cruciform shaft obliquity sensor is gathered two axial angles of inclination of driving platform, send programmable logic controller to, when any one arrives threshold value in two inclination angles that collect, director demon is after calculation process, send signal and give digital display, and on digital display, produce the sound and light alarm signal, remind the driver to note the angle of inclination of excavator, if the angle of slope become greater to when reaching dangerous values again and again, controller can send instruction through after the computing, continue to send sound and light alarm on the digital display, cut off the hydraulic oil source valve of excavator simultaneously, pin the action of excavator, prevent to tumble because of the excessive initiation excavator of angle.The excavator of this moment is in the lockup state of inclination angle protection; when the releasing locking switch of pressing elastic reset; controller receives signal through after the calculation process of program; recover the fuel feeding of oil sources valve at once; but the sound and light alarm of digital display continues to remind the driver, and the angle of slope of adjusting up to the driver returns to safe condition.
Claims (1)
1. rollover protection system is characterized in that reaching the software of independently writing by double cruciform shaft obliquity sensor, digital display, releasing locking switch, programmable logic controller forms; Inclination angle horizon sensor wherein, releasing locking switch are the input of controller, digital display, electronics executive component are controller output end, controller with totally-enclosed cuboid is that core is formed system, is mounted on the inclination angle horizon sensor of wheelhouse flat by lead; Said digital display, releasing locking switch, and output electronics executive component is installed in the driver's cabin.
