The specific embodiment
Below in conjunction with drawings and Examples a kind of split type intelligent type hydraulic hammer of the utility model is described further.
Found out that by Fig. 1, Fig. 2 a kind of split type intelligent type hydraulic hammer of the utility model is made up of impactor and controller two large divisions, controller places in main frame or the drivers' cab.Both link up by two hydraulic oil pipes 10 and 11.
Described impactor is to be made of piston 1, cylinder body 2, is the equipment of hydraulic hammer, is contained in the front end of work swing arm.
Described controller is to be made of two position three way directional control valve 3, high-speed switch electromagnetic valve 4, two pressure transmitters 5,6 and A/D converter (A/D) 7, computer (CPU) 8 and amplifier (AMP) 9, is the manipulation control section of hydraulic hammer.
Two pressure transmitters 5,6 and A/D converter (A/D) 7, computer (CPU) 8 and amplifier (AMP) 9, high-speed switch electromagnetic valve 4 are linked in sequence.
The ante-chamber a of described piston 1 adopts normal high pressure chest, promptly directly communicates with oil-in hydraulic oil P by hydraulic oil pipe 10 wherein; The back cavity b of described piston 1 is the transformation chamber, promptly by another root hydraulic oil pipe 11 directly and two-position three way control valve 3 link, alternately be connected with oil-in hydraulic oil P, oil return opening oil return T.Two position three way directional control valve 3 adopts spool-type valves, only is mated with a high-speed switch electromagnetic valve 4.The pressure transmitter 5 of controller is connected with the nitrogen chamber c of impactor, and pressure transmitter 5 both can be used to realize the commutation control of hydraulic hammer normal circulation, also can be used to discern the Based Intelligent Control of target physical-mechanical properties.

The course of work of a kind of split type intelligent type hydraulic hammer of the utility model is:
(1) drawback movement of hydraulic hammer
State when Fig. 1 represents that split type intelligent type hydraulic hammer is in backhaul and begins.At this moment, the direct UNICOM of hydraulic oil P of piston ante-chamber a and oil-in, piston back cavity b is then by oil pipe 11 and two position three way directional control valve 3 and oil return opening oil return T UNICOM.Like this, piston 1 overcomes the nitrogen resistance under the effect of hydraulic oil P, promotes piston 1 and makes drawback movement.During backward stroke of the piston, the volume in b chamber is reduced, fluid wherein drains into oil return opening by oil pipe 11 and valve 3.During backward stroke of the piston, increasing along with stroke, nitrogen among the nitrogen chamber c is compressed, pressure raises, when pressure is elevated to setting pressure---during prescribed stroke, detected by pressure transmitter, then computer (CPU) sends instruction at once, and amplify through AMP and to make high-speed switch valve 4 charged, make its spool be in position, a left side.At this moment the hydraulic oil of controlling oil circuit acts on two position three-way valve 3 through valve 4, makes its commutation, makes spool also be in position, a left side, and then the hydraulic oil P of working connection acts on the back cavity b of piston 1 through valve 3 and oil pipe 11.So the front/back cavity of piston 1 all bears the effect of the high pressure that pressure equates, and because of the pressure active area in two chambeies equates the direction counteracting on the contrary mutually of active force, inoperative to the motion of piston.But the nitrogen pressure that nitrogen chamber inner carrier end face is born has constituted the brake force of backward stroke of the piston motion, makes its on-position that enters backhaul, and speed reduces to zero very soon, has finished drawback movement.The end of a period of drawback movement is exactly the beginning of stroke.
(2) stroke movement of hydraulic hammer
Duty when Fig. 2 represents split type intelligent type hydraulic hammer piston stroke.State when finishing with the hydraulic hammer backhaul at this moment, is identical: piston 1 stops at top dead-centre; Reversal valve 3 is in position, a left side at the effect bottom spool of hydraulic oil P, the front/back cavity of piston all with hydraulic oil P UNICOM; High-speed switch electromagnetic valve 4 is charged, and its spool also is in position, a left side, and hydraulic oil P acts on valve 3 by valve 4; The computer of this moment has sent already and has made valve 4 charged instructions.
Piston 1 is under this state, and speed begins accelerated motion by zero, and rushes at bit shank output impact energy with the maximal rate of design; Meanwhile, pressure transmitter detects the signal of piston impact bit shank, after computer is received signal, send the instruction that makes valve 4 power interruption recovering normalities at once, so valve 4 dead electricity return to normal when beginning (state that hydraulic hammer is in backhaul), reversal valve 3 control chamber decompressions return to normal (spool is in right position), the back cavity b of piston 1 are communicated, for backhaul is got ready with oil return T through oil pipe 11.
2 explanations about pressure transmitter work:
When piston 1 impacted bit shank, pressure transmitter can detect two class signals:
(1) along with the carrying out of piston stroke, because the nitrogen pressure that piston tail progressively withdraws from wherein in the nitrogen chamber c descends gradually.When piston hits bit shank, pressure will be reduced to minimum (inflation power), and pressure transmitter thinks that promptly stroke finishes, and COMPUTER DETECTION is promptly sent the instruction that makes reversal valve 3 and magnetic valve 4 commutations behind this signal;
(2) after piston hits bit shank, pressure transmitter also can detect the signal of piston rebound velocity magnitude simultaneously, and at once give computer through A/D converter and handle, judge whether the physical-mechanical properties and the former output (impact energy and frequency) of hydraulic hammer target is consistent.Otherwise computer can mate output again according to the requirement of target, satisfies the job requirement of hydraulic hammer, realizes artificial intelligence, increases work efficiency.
Must be pointed out that the backhaul deboost phase of a kind of split type intelligent type hydraulic hammer of the utility model is identical with the oil circuit in stroke stage, as shown in Figure 2; The oil circuit of the backhaul accelerating sections of hydraulic hammer then as shown in Figure 1, this has just constituted the overall process of the complete working cycles of hydraulic hammer.
