Detailed description of the invention
In Fig. 1, signal acquisition circuit 2 can be following two kinds: the first is the travel switch comprised for detecting leg location state; Leg location travel switch exports digital quantity signal, is connected with the digital quantity input port of microcomputerized controller 3.The second is the pressure sensor comprised for detecting supporting leg hydraulic ram operation pressure; Supporting leg operation pressure detected pressures sensor exports analog signals, is connected with the analog input port of microcomputerized controller 3.
The status signal of the supporting leg of microcomputerized controller 3 Received signal strength Acquisition Circuit 2 input, when certain supporting leg travel switch signal effectively or the operation pressure of that supporting leg hydraulic ram on this supporting leg opposite exceed setting value, judge that this supporting leg derails, and the derailing signal of this supporting leg is transferred to Working mechanism controller 5 by bus protocol.
Working mechanism controller 5 receives the supporting leg derailing signal that microcomputerized controller 3 transmits, and outputs signal to output control circuit 6 and control Working mechanism operating magnet dead electricity, forbids that Working mechanism continues to the direction action that vehicle may be caused to topple.
Display circuit 4 is for showing the alarm message of supporting leg derailing.
Power circuit 7 is powered for microcomputerized controller 3 and Working mechanism controller 5.
During work, the status signal of gathered supporting leg is inputed to microcomputerized controller by signal acquisition circuit 2, microcomputerized controller passes through comparative analysis, judge whether the supporting leg of vehicle side derails, shown by display circuit 4, and the derailing information of supporting leg is transferred to Working mechanism controller 5 by J1939 communications protocol, and control Working mechanism operating magnet dead electricity by output control circuit 6, forbid that Working mechanism continues to the direction action that vehicle may be caused to topple.
In Fig. 2, wheel track monitoring device 1 mainly comprises connecting panel 11, blocking device 12, roller devices 13 and air bellow 14.Wheel track monitoring device 1 is arranged on the both sides of supporting leg 8, is connected with supporting leg 8 by connecting panel 11.When supporting leg 8 and wheel track monitoring device 1 are put down, roller devices 13 is fallen on rail, and along with rising or the decline of supporting leg 8, air bellow 14 compresses thereupon or extends, and roller devices 13 is corresponding to move to close or away from supporting leg 8 direction.When vehicle carries out high-speed cruising, when not needing to use supporting leg 8 and wheel track monitoring device 1, by blocking device 12, wheel track monitoring device 1 is locked on supporting leg 8, guarantees traffic safety.
Wheel track monitoring device 1 is packed up and is put down two states.When vehicle carries out high-speed cruising, supporting leg 8 and wheel track monitoring device 1 are all packed up and lock, and are positioned at above rail.When operation institution staff, supporting leg 8 stretches out, and wheel track monitoring device 1 puts down simultaneously, and supporting leg 8 and wheel track monitoring device 1 all drop on rail level.In operation process, when Working mechanism stretches out outside, a vehicle left side (right side) side certain distance, car body left (right side) rolls tiltedly, the supporting leg of the car body right side (left side) side can move up along with car body, wheel track monitoring device 1, owing to linking together with supporting leg 8, also rises along with supporting leg and moves to supporting leg longitudinal centerline direction.Along with supporting leg rises gradually, the connecting panel 11 of wheel track monitoring device 1 both sides can collide the contact of supporting leg 8 upper stroke switch, a digital quantity signal is inputted to microcomputerized controller, represent that now right (left side) side leg has left rail rail level, if Working mechanism continues, (right side) side is overhanging left, likely causes car load to topple.If the travel switch on right (left side) side leg does not have action, but the supporting leg of left (right side) side is due to car body (right side) inclination left, and tiltedly, the load-carrying of bearing will inevitably strengthen gradually, and the operation pressure of left (right side) side leg hydraulic ram also will increase gradually; When microcomputerized controller detects that the operation pressure of a left side (right side) side leg hydraulic ram exceedes setting value, also this signal can be transferred to Working mechanism controller by J1939 communications protocol, Working mechanism controller will limit Working mechanism continuation, and (right side) side is overhanging left, or only allows Working mechanism (left side) side action to the right.
No matter that the operation pressure of travel switch action on the supporting leg of left side or right side supporting leg hydraulic ram exceedes setting value (car body is tilted to the right), or the operation pressure of left side supporting leg hydraulic ram exceedes the travel switch action (car body is tilted to the left) on setting value or right side supporting leg, Working mechanism controller all can limit the scope of work of Working mechanism, ensures job safety.
