Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but described in claimed scope is not limited to.
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, a kind of pick-up unit of automatic detection excavator digging efficiency, comprise analogue enlargement oil circuit, fictitious load oil circuit and control system, described analogue enlargement oil circuit is by oil sump 11, oil pump 10, electromagnetism is than row valve 8, reversal valve A7 is linked in sequence composition, described fictitious load oil circuit is by reversal valve B4, electrohydraulic servo valve 2, oil sump 11 is linked in sequence composition, described control system is by pressure transducer B5, flow sensor 3, pressure transducer A6, Displaying Meter 14 and electronic control unit 13 form, described pressure transducer A6, flow sensor 3, pressure transducer B5 is connected with electronic control unit input end respectively, described Displaying Meter 14, electrohydraulic servo valve 2, electromagnetism is connected with electronic control unit 13 output terminal respectively than row valve 8.
During excavator work, for excavator hydraulic system provides power after hydraulic oil in oil sump 11 is pressurizeed by oil pump 10, excavator hydraulic system drives each component movement of excavator, realize various excavation action, therefore, detect excavator digging efficiency and namely detect the efficiency of excavator hydraulic system when excavating.Hydraulic oil after pressurization is first transported to main valve 12 by oil pipe, adjusts behind running of hydraulic power oil direction be transported to executive component 1 through main valve 12, can realize controlling the action of executive component 1 by control bound 12.When executive component 1 is hydraulic cylinder, the spool of main valve 12 to the right time, hydraulic cylinder stretches out to the right, the spool of main valve 12 left time, hydraulic cylinder is retracted; When executive component 1 is oscillating motor, the spool of main valve 12 to the right time, oscillating motor turns clockwise, the spool of main valve 12 left time, oscillating motor is rotated counterclockwise.In order to easy to operate, the spool of main valve 12 adopts hydrostatic control, spool the right and left of main valve 12 is respectively arranged with guide's oil circuit, this guide oil route oil pump 10, manual switch valve 9, reversal valve A7 connect to form, open manual switch valve 9 during operation, promotion reversal valve A7 can realize the control to main valve 12 spool.
In order to realize further controlling excavator hydraulic system, the oil circuit control of excavator executive component 1 adds analogue enlargement oil circuit and fictitious load oil circuit, and increase pressure and flow detection point.On guide's oil circuit of main valve 12, increase by one to be linked in sequence the analogue enlargement oil circuit formed than row valve 8, reversal valve A7 by oil sump 11, oil pump 10, electromagnetism, wherein electromagnetism is more in parallel with the manual switch valve 9 in the oil circuit control of executive component 1 than row valve 8, and electromagnetism is connected with electronic control unit 13 by signal wire than row valve 8; Increase at executive component 1 oil pocket import and export and to be linked in sequence the fictitious load oil circuit formed by reversal valve B4, electrohydraulic servo valve 2, oil sump 11, executive component 1 is imported and exported oil circuit and is divided into two-way by reversal valve B4, wherein a road is imported and exported with executive component 1 and is connected, another road is connected with electrohydraulic servo valve 2, and electrohydraulic servo valve 2 is connected with electronic control unit 13 by signal wire.Between guide's oil circuit oil-in and reversal valve A7 oil-out of main valve 12, increase pressure transducer B5, pressure transducer B5 is connected with electronic control unit 13 by signal wire; Between main valve 12 oil-out and reversal valve B4 oil-in, increase pressure transducer A6, pressure transducer A6 is connected with electronic control unit 13 by signal wire; Between reversal valve B4 oil-out and electrohydraulic servo valve 2 oil-in, increase flow sensor 3, flow sensor 3 is connected with electronic control unit 13 by signal wire.
When using the technical program, testing staff's manual operation reversal valve A7, executive component 1 is made to start to perform an action, now electronic control unit 13 starts to store by pressure transducer B5, the numerical value that pressure transducer A6 feeds back, after action executing, electronic control unit 13 have recorded the various parameters performed needed for this action, then, the reversing valve operated B7 of testing staff switches to analogue enlargement oil circuit, reversing valve operated B4 switches to fictitious load oil circuit, start the autotest of this device, electronic control unit 13 is just by controlling electromagnetism than the duty of main valve 12 guide oil circuit during testing staff's manual operation before row valve 8 modulating output, simultaneously, electronic control unit 13 controls various load conditions when electrohydraulic servo valve 2 simulates hydraulic work system.Pressure transducer A6, pressure transducer B5, flow sensor 3 by the data feedback that detects to electronic control unit 13, by contrasting not pressure output value in the same time collected by this device, flow output valve, pressure feedback value, flow feedback value thus the accurate evaluation realized excavator digging efficiency, and comparing result is shown on Displaying Meter 14 with the form of data or image.In order to observe conveniently, electronic control unit 13 and Displaying Meter 14 are integrated on same pcb board.The hydraulic system element used due to different excavators is different, when executive component 1 performs an action, the correlation parameter of whole hydraulic system is different, when using the technical program to detect first excavator, testing staff must debug in manual operation, avoids damaging excavator.
