Description
Technical field
The present invention relates to a kind of methods suitable for the control of ultra-large type excavator stair, belong to ultra-large type excavator technology neck
Domain.
Background technology
Ultra-large type excavator is mainly used for large-scale mine, and feature is that its appearance and size is larger, needs stair that could enter and digs
It is operated or is repaired in pick machine.The expansion and withdrawal of stair carry out realizations hand-manipulated by two buttons.When ultra-large type is dug
When pick machine carries out operation, stair must be withdrawn, and stair can be damaged when otherwise turning round.Driver often occurs to forget to withdraw stair and grasp
Make ultra-large type excavator, stair are damaged, cause bigger economic loss.
Invention content
The object of the present invention is to provide a kind of methods suitable for the control of ultra-large type excavator stair, ensure that ultra-large type is dug
Stair are in retracted state when pick machine carries out operation, and damage stair is avoided to cause damages.
The technical solution adopted by the present invention is as follows：
A kind of method suitable for the control of ultra-large type excavator stair, which is characterized in that controller is detected to expansion button or receipts
When returning the expansion stair signal of button or withdrawing stair signal, according to withdrawing close to switch, expansion close to switch, unlock close to opening
Close to switch and/or the signal of dead-man's handle switch feedback, control solves latching solenoid valve, lock-up solenoid valve, withdrawal electromagnetism for pass, locking
Valve and/or expansion solenoid valve cooperation perform corresponding action.
When controller detects expansion button closure signal, then dead-man's handle on off state is detected, if dead-man's handle is opened
It closes and closes, perform stair expansion operation, otherwise do not allow.
When dead-man's handle, which switchs, to be closed, controller detects the close switch of withdrawal and locking close to switch closure signals
When, driving solution latching solenoid valve is unlocked stair, when detecting that unlock is closed close to switch, stops driving unlock electromagnetism
Valve.
Controller driving expansion electromagnetism valve events make under stair exhibition, when detection is unfolded to be closed close to switch, stop driving
Solenoid valve is unfolded, stair complete expansion operation.
When controller detects withdrawal button closure signal, and detect that expansion is closed close to the nearly switch of switch reconciliation interlocking
It closes, driving withdraws electromagnetism valve events and withdraws stair, when detecting that withdrawal is closed close to switch, stops driving and withdraws solenoid valve,
Stair are retracted.
After stair are retracted, controller driving lock-up solenoid valve action carries out locking to stair, when detecting that locking approaches
When switch is closed, stop driving solution latching solenoid valve.
The present invention mainly has following main points during control：
1st, when controller detects expansion button closure signal, then dead-man's handle on off state is detected, if dead-man's handle switchs
It is closed, performs stair expansion operation, otherwise do not allow.
2nd, controller detects that withdrawal is closed close to switch and locking close to switch, driving solution latching solenoid valve, when detecting
When unlock is close to switch closure, stop driving solution latching solenoid valve 7.
3rd, controller driving expansion solenoid valve when detection is unfolded to be closed close to switch, stops driving expansion solenoid valve.
4th, stair complete expansion operation, and driver is exactly to open dead-man's handle switch at this time, and controller will not drive super large
The operation of type excavator, protects stair.
5th, when controller detects withdrawal button closure signal, and detect that expansion is closed close to the nearly switch of switch reconciliation interlocking
It closes, solenoid valve is withdrawn in driving, when detecting that withdrawing close switch is closed, stops driving withdrawal solenoid valve.
6th, controller driving lock-up solenoid valve when detecting that locking is closed close to switch, stops driving solution latching solenoid valve.
7th, stair complete recovery operation, and driver can open dead-man's handle switch and carry out operation at this time.
The advantageous effect that the present invention is reached：
Controller of the present invention is to carry out by the real-time status close to switch detection stair, and according to the operation judges stair of button
Expansion or withdrawal.Dead-man's handle on off state is detected simultaneously, expansion and the receipts of stair could be carried out when dead-man's handle is closed
It returns, the method that this method is suitable for the control of ultra-large type excavator stair, ensure that ultra-large type excavator is carried out during operation at stair
In retracted state, damage stair is avoided to cause damages.
Description of the drawings
Fig. 1 is the schematic diagram of ultra-large type excavator stair control.
1. withdraw close to switching in figure, and 2. are unfolded close switch, and 3. unlocks are close to be switched, the close switch of 4. lockings, 5. peaces
Full bat-handle switch, 6. controllers, 7. solution latching solenoid valves, 8. lock-up solenoid valves, 9. withdrawal solenoid valves, 10. expansion solenoid valves, 11.
Button is unfolded, 12. withdraw button.
Specific embodiment
The invention will now be described in further detail with reference to the accompanying drawings：
As shown in Figure 1, the method for the present invention, when controller 6 detects expansion 11 closure signal of button, represents that driver wants to carry out
The operation of stair expansion.Controller 6 detects dead-man's handle and switchs 5 states, if dead-man's handle switch 5 is closed, expression surpasses at this time
Large excavator does not carry out operation, and stair is allowed to be unfolded, are not otherwise allowed.The detection of controller 6, which is withdrawn close to switch 1 and locking, to be connect
The state of nearly switch 4, is closed if withdrawn close to switch 1 and locking close to switch 4, represents that stair are in retracted state, can be with
Perform stair unlock operation.The driving solution latching solenoid valve 7 of controller 6 is unlocked stair, while detect unlock close to switch 3
State when unlock is closed close to switch 3, represents that unlocking mechanism completes the unlock to stair, controller 6 stops driving unlock electricity
Magnet valve 7 can perform stair expansion operation.The driving expansion action of solenoid valve 10 of controller 6 makes under stair exhibition, while detect expansion
Close to the state of switch 2, when expansion is closed close to switch 2, represent that stair expand in place, controller 6 stops driving expansion electricity
Magnet valve 10.Stair complete expansion operation, and driver is exactly to open dead-man's handle switch 5 at this time, and controller 6 will not drive ultra-large type
The operation of excavator, protects stair.
When controller 6 detects withdrawal 12 closure signal of button, represent that driver wants to carry out the operation of stair withdrawal.Controller
The state of interlocking closely switch 3 is conciliate in 6 detection expansion close to switch 2, if expansion is closed close to 1 reconciliation interlocking closely switch 3 is switched,
It represents that stair are in unfolded state, stair recovery operation can be performed.The driving of controller 6 withdraws the action of solenoid valve 9 and withdraws stair,
The state withdrawn close to switch 1 is detected simultaneously, when withdrawal is closed close to switch 1, represents stair withdrawal in place, controller 6 stops
Only solenoid valve 9 is withdrawn in driving, can perform the operation of stair locking.The driving of controller 6 lock-up solenoid valve 8, which acts, locks stair
Only, while locking is detected close to the state of switch 4, when locking is closed close to switch 4, represent that lockable mechanism is completed to stair
Locking, controller 6 stop driving solution latching solenoid valve 8.Stair complete recovery operation, and driver can open dead-man's handle switch at this time
5 carry out operation.
