The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further specified.Embodiment is used to explain the utility model, limits the utility model never in any form.
In conjunction with Fig. 1, Fig. 2.
General 8 valves cutting rig hydraulic control system; Comprise that main pump 30,8 main control valves 80 control respectively that the boom cylinder 31, bucket arm cylinder 33, air compressor machine motor 32, ejector dozer oil cylinder 36, drilling hoist cylinder 34, drilling and cutting machine motor 35, rotary motor 37, the left lateral that connect are walked motor 39 and right lateral is walked motor 38 function executing elements, 34 controls connect the wherein a slice control valve in 8 main control valves 80 with the drilling hoist cylinder with ejector dozer oil cylinder 36 respectively through solenoid operated directional valve Y5.There is second an electromagnetic valve Y2 who is used to switch excavator pattern and cutting rig pattern and forms interlocking in the control system.Be respectively applied for the electromagnetic valve Y 4 of control air compressor machine motor operations and the electromagnetic valve Y3 of drilling motor operations in addition.
The general 8 valves cutting of the utility model rig hydraulic control system other control system is a classical control system.The utility model provides a kind of safety, the general 8 valves cutting rig hydraulic control system that can between digging machine pattern and rig pattern, freely switch easily and efficiently.
Among the figure; Y2 is that implementation pattern switches the also electromagnetic valve of self-locking, and Y3 is under the rig pattern, the electromagnetic valve of control drilling motor 35 work; Y4 is under the rig pattern; The electromagnetic valve of control air compressor machine motor 32 work, Y5 is implemented under digging machine pattern and the rig pattern, the electromagnetic valve of hoist cylinder 34 oil circuits and the switching-over of ejector dozer oil cylinder 36 oil circuits.
As shown in Figure 1, the general 8 valves control cutting drilling machine hydraulic system that the utility model provides increases air compressor machine motor 32, drilling hoist cylinder 34,35 3 executive components of drilling and cutting machine motor on original excavator hydraulic system.Formation boom cylinder 31, bucket arm cylinder 33, air compressor machine motor 32, ejector dozer oil cylinder 36, drilling hoist cylinder 34, drilling and cutting machine motor 35, rotary motor 37, left lateral are walked motor 39, right lateral is walked motor 38 totally 9 executive components.Can know that by general excavator hydraulic system design principle a used executive component of function controlled by a plate valve separately.Generally, digging machine change the cutting rig need select for use one 9 valve to be used as the main control valve of drilling rig hydraulic system.Switch drilling hoist cylinder 34 oil circuits, ejector dozer oil cylinder 36 oil circuits and utilized cleverly in the utility model, and then reduced by a plate valve, reached the purpose of multi-purpose valve through a solenoid operated directional valve Y5.
On former excavator control system basis, added a digging machine pattern and the rig pattern is switched the second electromagnetic valve Y2.The second electromagnetic valve Y2 dead electricity under the digging machine pattern; The guide control oil wherein a route second electromagnetic valve Y2 left side bit stream go into a minute fluid; And then get into left and right sides guide's handrail pilot valve P mouth, about walking pilot valve P mouth, thereby control boom cylinder 31, bucket arm cylinder 33, rotary motor 37, left lateral are walked motor 39, right lateral is walked motor 38 these executive components.Another road guide controls oil and flows directly into the ejector dozer pilot valve, and then controls the operation of the 7th valve, switching-over.Meanwhile solenoid operated directional valve Y5, the 4th electromagnetic valve Y4, the 3rd electromagnetic valve Y3 are in dead electricity under the digging machine pattern; So the ejector dozer working connection is by the right position entering of solenoid operated directional valve Y5 ejector dozer oil cylinder 36, at this moment the no oil circuit of drilling hoist cylinder 34 UNICOM does not have the action execution.Moreover the 4th electromagnetic valve Y4, the 3rd electromagnetic valve Y3 are in the dead electricity situation and are in position, a left side at this moment, and drilling motor 35 directly links with the tank drainback road through the 4th electromagnetic valve Y4, left of the 3rd electromagnetic valve Y3 respectively with air compressor machine motor 32 guide's control oil channel.So this moment, air compressor machine motor 32 did not have the action execution with drilling and cutting machine motor 35.Under the digging machine pattern, just only realize the excavator function like this.
Under the rig pattern, the second electromagnetic valve Y2, the 4th electromagnetic valve Y4 and solenoid operated directional valve Y5 simultaneously electric, this moment, the guide control oil channel was wherein one the tunnel directly identical with ejector dozer guide handle valve, and then controlled the operation of the 7th valve, commutates.Because it is electric that solenoid operated directional valve Y5 gets, the 7th valve working connection is identical with drilling hoist cylinder 34 oil circuits through position, a solenoid operated directional valve Y5 left side, and drilling this moment hoist cylinder 34 can be carried out action, and ejector dozer oil cylinder 36 does not have action.Other one tunnel guide's control oil channel communicates with air compressor machine the 4th electromagnetic valve Y4 and rig the 3rd electromagnetic valve Y3 oil inlet P mouth through the right position of the second electromagnetic valve Y2, and then can go to control air compressor machine motor 32,35 work of drilling and cutting machine motor.This moment left and right sides handrail pilot valve with about walking pilot valve oil-in be cut off, boom cylinder 31, bucket arm cylinder 33, rotary motor 37, left lateral are walked motor 39, right lateral is walked motor 38 these executive components and do not had action.Air compressor machine the 4th electromagnetic valve Y4 when drill mode electric, guide's control oil channel directly communicates with the second air compressor machine motor control valve through the right position of the 4th electromagnetic valve Y4, thereby air compressor machine motor 32 is turned round.
Under the rig pattern, just have only drilling hoist cylinder 34, air compressor machine motor 32,35 3 executive components of drilling and cutting machine motor to move, so just well realized the quick of digging machine pattern and rig pattern; Safety is switched; Reach the interlocking effect, under the rig pattern, if the operator runs into because of carelessness; Other handle pilot valves of maloperation do not have action fully, and are as safe as a house reliable.And under the rig pattern, drilling hoist cylinder 34 is by the control of ejector dozer guide handle, and ejector dozer handle oil cylinder forward stretches out, and ejector dozer handle oil cylinder is backward withdrawn out.The connection switch of drilling the 3rd electromagnetic valve Y3 is the button that on ejector dozer handle head location, is provided with in addition, under the rig pattern, presses these button drilling and cutting machine motor 35 work and begins to carry out drilling work.Such hydraulic control system design has better met the human engineering principle, lets the safety operation of carrying out that the operator can be simply comfortable.
