Detailed description of the invention
In order to make those skilled in the art be more fully understood that this utility model scheme, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As it is shown in figure 1, this utility model one loader paced work hydraulic system Intelligent control system, including hydraulic oil container 1, working barrel 2, distributing valve 3, pioneer pump 4, Intelligent control module 5, pilot valve 6, rotary ink tank 7 and boom cylinder 8; The oil-in of described working barrel 2 is connected with hydraulic oil container 1, and the oil-out P1 of working barrel 2 is connected with the oil inlet P 2 of distributing valve 3; The oil-in of described pioneer pump 4 is connected with hydraulic oil container 1; Described Intelligent control module 5 is mainly made up of first, second electromagnetic valve V11, V12, first, second pressure transducer S1, S2, controller C1; Described control port P31, P32 of first, second electromagnetic valve V11, V12 are connected with the oil-out P3 of pioneer pump 4; Control port Pa1, Pa2 of first, second electromagnetic valve V11, V12 receives bucket action control hydraulic fluid port a1, boom arm lift action control hydraulic fluid port a2 respectively and is connected with the scraper bowl of distributing valve 3; Control port Pa1 ', the Pa2 ' of first, second electromagnetic valve V11, V12 receives bucket action control hydraulic fluid port a1, boom arm lift action control hydraulic fluid port a2 respectively and is connected with the scraper bowl of pilot valve 6; Described first pressure transducer S1 input is connected with rotary ink tank 7 rodless cavity; Described second pressure transducer S2 input is connected with boom cylinder 8 rodless cavity; Described controller C1 and first, second pressure transducer S1, S2 outfan are connected, and signal of telecommunication receiving port R1 and R2 of controller C1 outfan and first, second electromagnetic valve V11, V12 is connected; First, second electromagnetic valve V11, V12 is carried out commutation control according to receiving electrical signal status by R1 and R2. Thus realizing the Based Intelligent Control of duty switching after working barrel 2 outlet pressure oil P1 entrance distributing valve 3 oil inlet P 2. And after being finally completed scraper bowl spading and boom arm lift action, carry out automatic deloading, make the high pressure kicks heat producing losses of system reduce to zero, reach the purpose of hydraulic system of working efficient energy-saving.
This utility model controller C1 is provided with one for controlling the control knob of Intelligent control module 5 switch. So that realizing " key operation " function.
Mainly introduce the operation of this utility model functional realiey below and control thinking.
One, condition is controlled:
" key operation " refers to that the duty of Intelligent control module 5 opened by an individually operated control knob; Not carrying out " key operation ", Intelligent control module 5 does not work.
After carrying out " key operation ", if first, second equal no signal output (namely rotating bucket cylinder and swing arm cylinder rodless cavity pressure are all less than setup pressure value) of pressure transducer S1, S2, then R1 and R2 is in electriferous state, and the electriferous state of R1 and R2 is independent mutually, body controls condition and route with reference to shown in Fig. 2 and Fig. 3.
Two, control principle and scheme:
When loader uses Intelligent control module 5 to proceed by spading action, Intelligent control module 5 is utilized to carry out " key operation ", and be maintained with pilot valve 6 and be in middle position: now rotary ink tank 7 and boom cylinder 8 rodless cavity not yet really carry out due to spading action, both are low pressure (exporting setting value lower than pressure sensor signal), the first, second equal no signal output of pressure transducer S1, S2; Now the controller C1 in Intelligent control module 5 receives only " key operation " signal and processes, after process, signal transmits to electrically-controlled valve group V1 signal receiving port R1 and the R2 in Intelligent control module 5 simultaneously, electrically-controlled valve group V1 receive signal R1 and R2 simultaneously electric and carry out commutation action (after commutation, in electrically-controlled valve group V1, control port P31 and Pa1 is connected, and P32 and Pa2 is connected). After electrically-controlled valve group V1 commutation, pioneer pump 4 delivery outlet P3 exports pilot control oil respectively to P31 and P32, and now oil circuit control connected state is illustrated in fig. 4 shown below.
Under oil circuit control connected state shown in Fig. 4, distributing valve 3 rotating bucket connection spool moves to scraper bowl after pioneer pump 4 pressure output control the allocated valve 3 rotating bucket joins a1 control port effect and receives bucket operating position; Distributing valve 3 swing arm connection spool moves to boom arm lift operating position after pioneer pump 4 pressure output control the allocated valve 3 swing arm joins a2 control port effect. Reviewing distributing valve 3, it may be seen that this distributing valve 3 is made preferential for rotating bucket linkage, therefore now loader preferentially carries out scraper bowl spading (receiving bucket) action; And though swing arm connection spool is in boom arm lift position, but owing to no pressure oil inputs, swing arm attonity. In loader spading process, first pressure transducer S1 monitors rotating bucket cylinder rodless cavity pressure always, in spading action implementation process, rotating bucket oil cylinder rodless cavity pressure can gradually rise to the first pressure transducer S1 signal output setting value, now the first pressure transducer S1 exports R1 power-off in signal controller C1 electrically-controlled valve group V1, the first electromagnetic valve V11 commutation extremely right working position; Now distributing valve 3 rotating bucket connection a1 control port connects with hydraulic oil container 1, rotating bucket connection spool Hui Zhongwei, and in working barrel 2 pressure oil output the allocated valve 3 rotating bucket connection spool, bit stream joins spool boom arm lift position to swing arm.
By said process, at this moment realize " seamless switching " of loading shovel spading action and boom arm lift action. Now carry out boom arm lift action, same second pressure transducer S2 monitors swing arm cylinder rodless cavity pressure always, in boom arm lift action implementation process, boom cylinder rodless cavity pressure can gradually rise to the second pressure transducer S2 signal output setting value, now the second pressure transducer S2 exports R2 power-off in signal controller C1 electrically-controlled valve group V1, the second electromagnetic valve V12 commutation extremely right working position; Now distributing valve 3 swing arm connection a2 control port connects with hydraulic oil container 1, swing arm connection spool Hui Zhongwei, working barrel 2 pressure oil output the allocated valve 3 rotating bucket connection spool in position and swing arm connection spool in bit stream be back to fuel tank (it is assumed that be first, second pressure transducer S1, S2 pressure monitored, it is and exceeds setting value), realize the automatic deloading of hydraulic system of working, do not have the situation of high pressure kicks, reach the purpose of fixed dilivery hydraulic system efficient energy-saving.
Note: if any one pressure detected of two pressure transducers is lower than setting value, then its corresponding equipment action (scraper bowl spading receives bucket or boom arm lift) continues " seamless switching " and carries out, until two pressure transducers all reach setup pressure value, rotating bucket connection spool and the swing arm connection spool of distributing valve 3 are in middle position all automatically, whole hydraulic system of working intelligence off-load, increases complete machine pull strength while energy-conservation.
Certainly, above-described embodiment is only preferred version of the present utility model, is specifically not limited thereto, and can make pointed adjustment on this basis according to actual needs, thus obtaining different embodiments. Owing to mode in the cards is more, just no longer illustrate one by one here.
