Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail, can be easier to be readily appreciated by one skilled in the art, thus make more explicit defining to protection scope of the present invention to make advantages and features of the invention.
As shown in Figure 1, a kind of rig electrichydraulic control anticollision device, comprises hydraulic system, electrical system and actuator.Wherein, hydraulic system comprises pilot valve 1, pilot operated directional control valve 2, motor 3, pump 4, relief valve 5, reduction valve 6,2/2-way solenoid directional control valve 7, touch switch 8 and fuel tank 9.
The P mouth of described pump 4 and pilot operated directional control valve 2, the P mouth of relief valve 5, the P mouth of reduction valve 6 are connected, and the T mouth of the T mouth of pump 4, the T mouth of relief valve 5, pilot operated directional control valve 2 is connected with fuel tank 9 respectively;
A, B mouth of described pilot operated directional control valve 2 is connected respectively with B, A mouth of motor 3, and a1, a2 mouth of pilot valve 1 is connected respectively with a, b mouth of pilot operated directional control valve 2;
The A mouth of described reduction valve 6 and the P mouth of 2/2-way solenoid directional control valve 7, the A mouth of 2/2-way solenoid directional control valve 7 is connected successively with the P mouth of pilot valve 1.
Before electrical system powers on, detect each block position by proximity switch 8, and testing signal sent into controller 14, controller 14 read in this SC sigmal control respectively corresponding solenoid directional control valve 7 whether electricly need.
When lifting gear pivoted arm 13 is positioned at safety zone, touch switch 8 does not touch boss 11 and disconnects, 2/2-way solenoid directional control valve 7 is in left position, conducting between reduction valve 6 and pilot valve 1, can control pilot operated directional control valve 2 commutate thus control motor 3 and feed and promote by manipulation pilot valve 1.
When lifting gear pivoted arm is positioned at hazardous area, touch switch 8 is connected, and 2/2-way solenoid directional control valve 7 commutates to right position, and now the uncontrollable pilot operated directional control valve 2 of manipulation pilot valve 1 commutates thus avoids motor 3 and feeds and promote.
When pivoted arm 13 is positioned at limit position, as long as swing arm stops, stop location is not reversed and recalls, then corresponding touch switch 8 state remains closed always, corresponding solenoid valve 7 keeps obtaining electricity condition always, until when block is oppositely recalled, proximity switch then disconnects, corresponding solenoid valve 7 dead electricity, thus the coordination of the periodic motion of the system of guarantee.
Electric liquid joint control anticollision device of the present invention adopts touch switch to realize safety control, avoids existing truck-mounted drilling rig misoperation and the device damage that causes or casualties, improves rig Security and operability.
Last it is noted that obviously, above-described embodiment is only for example of the present invention is clearly described, and the restriction not to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And thus the apparent change of amplifying out or variation be still among protection scope of the present invention.
