Summary of the invention
The purpose of the utility model provides that a kind of driving force is big, and load capacity is strong, and the leveling time is short, be out of shape for a short time, and repeatability is little, stable high car launcher job platform levelling device.
The purpose of the utility model realizes through following technical scheme: a kind of car launcher job platform levelling device; Comprise main frame, ECU, hydraulic control system, preceding left branch leg oil cylinder, preceding right support oil cylinder, back left branch leg oil cylinder, the right support oil cylinder in back; The degree of tilt pick-up unit; Said main frame is connected with ECU, hydraulic control system respectively through data line; Said hydraulic control system is connected with ECU through data line; Said hydraulic control system is connected with preceding left branch leg oil cylinder, preceding right support oil cylinder, back left branch leg oil cylinder, the right support oil cylinder in back respectively through oil circuit; On left branch leg oil cylinder, preceding right support oil cylinder, back left branch leg oil cylinder, the right support oil cylinder inwall in back the pressure transducer (not shown in figure 1) is housed respectively before said; Through the signal wire (not shown in figure 1) that is connected with ECU, said tilt detecting device is fixed on the job platform through screw rod all pressure transducers, is provided with the cruciform mercury cell in the said degree of tilt pick-up unit respectively; Said mercury cell center is provided with pit; Mercury is housed in the pit, and be equipped with respectively and preceding left branch leg oil cylinder, preceding right support oil cylinder, back left branch leg oil cylinder, the corresponding pressure transducer I of the right support oil cylinder in back, pressure transducer II, pressure transducer III, pressure transducer IV said mercury cell end, and said pressure transducer I, pressure transducer II, pressure transducer III, pressure transducer IV are connected with ECU through signal wire respectively.
Said main frame is a microcomputer.
Said ECU is an electronic control unit, claims " car running computer ", " vehicle-mounted computer " etc. again.Say it is the automobile microcomputerized controller from purposes at present, also be the automobile single-chip microcomputer.It is the same with common single-chip microcomputer, is made up of large scale integrated circuits such as microprocessor (CPU), storer (ROM, RAM), input/output interface (I/O), analog to digital converter (A/D) and shaping, drivings.The function of ECU is to carry out computing, processing, judgement according to the information that the program of its internal memory and data are taken into account various sensors inputs to air mass flow, output order then, and the electric impulse signal that certain width is provided to fuel injector is with the control distributive value.ECU is made up of microcomputer, input, output and control circuit etc.
Hydraulic control system is a hydraulic control system, and in its unique double spool control technology, every plate valve has two spools to its key at multiple directional control valve; Be equivalent to a three-position four-way valve is become the combination of two 3-position-3-way valves, two spools both can be controlled separately, also can be carried out to control according to steering logic; And two actuator ports all have pressure transducer; Each spool is position sensor all, can control the pressure or the flow of two-way hydraulic oil respectively through the closed-loop control to transducing signal, has very high control accuracy; Multiple directional control valve can obtain various controlling schemes through different combinations, to satisfy the needs of system.
The utility model is mainly realized the leveling process through the variation of measuring mercury gravity, and this system adopts hydraulic-driven, and driving force is big, and load capacity is strong, can realize automatic leveling process preferably.
Description of drawings
Fig. 1 is the utility model example structure block diagram;
Fig. 2 is a degree of tilt pick-up unit structural drawing shown in Figure 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
With reference to accompanying drawing; Present embodiment comprises main frame 2, ECU3, hydraulic control system 1, preceding left branch leg oil cylinder 4, preceding right support oil cylinder 5, back left branch leg oil cylinder 6, the right support oil cylinder 7 in back; Also be provided with a degree of tilt pick-up unit; Said main frame 2 is connected with ECU3, hydraulic control system 1 respectively through data line; Said hydraulic control system 1 is connected with ECU3 through data line; Said hydraulic control system 1 is connected with preceding left branch leg oil cylinder 4, preceding right support oil cylinder 5, back left branch leg oil cylinder 6, the right support oil cylinder 7 in back respectively through oil circuit; On left branch leg oil cylinder 4, preceding right support oil cylinder 5, back left branch leg oil cylinder 6, right support oil cylinder 7 inwalls in back the pressure transducer (not shown in figure 1) is housed respectively before said; Through the signal wire (not shown in figure 1) that is connected with ECU3, said degree of tilt pick-up unit 10 is fixed on the job platform 16 through screw rod 15 all pressure transducers, is provided with cruciform mercury cell 8 in the said degree of tilt pick-up unit 10 respectively; Said mercury cell 8 centers are provided with pit 9; In the pit 9 mercury is housed, be equipped with respectively and the corresponding pressure transducer I of the right support oil cylinder of preceding left branch leg oil cylinder 4, preceding right support oil cylinder 5, back left branch leg oil cylinder 6, back 7 11, pressure transducer II 12, pressure transducer III 13 and pressure transducer IV 14 said mercury cell 8 ends, and said pressure transducer I 11, pressure transducer II 12, pressure transducer III 13 are connected with ECU3 through signal wire respectively with pressure transducer IV 1414.
During work; If job platform 16 is in heeling condition, then the liquid mercury in the mercury cell 8 center pits 9 will flow to lower mercury cell 8 ends, because the gravity of mercury self; Can make the pressure transducer pressure of this end become big; Pressure signal passes to ECU3 through signal wire and converts digital signal to and be presented on the operation panel, and the staff sends the instruction of job platform being carried out leveling through main frame 2 to hydraulic control system 1, left branch leg oil cylinder 4 before hydraulic control system 1 drives, preceding right support oil cylinder 5, the right support oil cylinder 7 of back left branch leg oil cylinder 6 or back; Make the big corresponding oil cylinder piston of pressure stretch out a segment length; Make the liquid mercury of this end slowly flow to middle pit, equal pressure shows that illustrative system had been in horizontality when numerical value was tending towards the horizontal pressure force displayed value.Generally less pressure display value is not adjusted, because the withdrawal of oil cylinder supporting leg might make tire land, this is not fill to be permitted.
