Background technology
Hydraulic jack is a kind of conventional Hydraulic for lifting load instrument, when product manufacturing, sale and use, often needs the performance to product to carry out the detection evaluation of objective science.In prior art, detection equipment can only fictitious load power and manual operation, its produced problem need to be carried out manual analysis judgement, there is detection efficiency low, the problem that automaticity is low.
China Patent No. 201210306394 discloses name and is called the patent of " hydraulic jack test device ", without the pump core of tested hydraulic jack and pump core actuating mechanism being connected by test work, thus the working strength of test work can be alleviated, and can two hydraulic jack be tested simultaneously, improve efficiency, but also needing to more manual operation and analyze judgement, automaticity is low, it does not have overcome drawbacks described above of the prior art.
China Patent No. 200910096088 discloses name and is called the patent of " load dynamic pretest system for hoisting jack ", jack dynamic load is simulated by hydraulic system, automatically record jack change of pressure and stroke in elevation process, jack is carried out prerun, reach to accelerate prerun speed, reduce the effect of labor intensity, but load is monitored by it, and simply a kind of dynamic data record prerun to jack, data are sufficient not, the data obtained can not be identified automatically judgement, also common failure cause cannot be analyzed, do not overcome drawbacks described above of the prior art well.
Summary of the invention
It is an object of the invention to overcome above shortcomings in prior art, and the Multifunctional intelligent oil jack test machine that a kind of reasonable in design, detection efficiency are high, automaticity is high, data binding analysis ability is strong is provided.
This invention address that the problems referred to above be the technical scheme is that, this Multifunctional intelligent oil jack test machine includes: hydraulic control system, frame, data collecting system and computer, it is characterized in that: described frame is provided with operating cyloinder and loading cylinders, operating cyloinder and loading cylinders and is all connected with hydraulic control system；Described operating cyloinder is provided with displacement transducer one and force cell one, loading cylinders is provided with displacement transducer two and force cell two；Described displacement transducer one, displacement transducer two, force cell one and force cell two are all connected with data collecting system, and data collecting system is connected with computer.Hydraulic control system provides pressure to operating cyloinder and loading cylinders, and operating cyloinder acts on the handle of jack, simulates the operation of artificial handle；Loading cylinders acts on the weight bearing area of jack, fictitious load operating mode；Displacement transducer one and force cell one measure shift value and the force value of operating cyloinder, displacement transducer two and force cell two and measure shift value and the force value of loading cylinders；The data of data acquisition system displacement transducer one, displacement transducer two, force cell one and force cell two, the data of data acquisition system are identified judgement, analyzing failure cause by computer automatically.
Operating cyloinder of the present invention and loading cylinders are arranged on the top of frame, displacement transducer one and force cell one and are arranged on the bottom of operating cyloinder, displacement transducer two and force cell two and are arranged on the bottom of loading cylinders.
Hydraulic control system of the present invention provides pressure to operating cyloinder and loading cylinders, and operating cyloinder acts on the handle of jack, and loading cylinders acts on the weight bearing area of jack；Described displacement transducer one and force cell one measure shift value and the force value of operating cyloinder, displacement transducer two and force cell two and measure shift value and the force value of loading cylinders；The data of described data acquisition system displacement transducer one, displacement transducer two, force cell one and force cell two, the data of data acquisition system are identified judgement, analyzing failure cause by computer automatically.
When the present invention tests, there is following several situation and analyze result:
(1) when jack is in the position that hoists, at the appointed time, permanent load is applied: if loading cylinders decline displacement is in setting value, jack is qualified；If loading cylinders decline displacement exceedes setting value, there is force value and shift value change, then jack Outlet check valves poor sealing in operating cyloinder；If loading cylinders decline displacement exceedes setting value, operating cyloinder force value and shift value are unchanged, then jack piston poor sealing or cylinder bottom poor sealing；
(2) when jack is in the position that hoists, opening oil return valve, loading cylinders is to press under constant speed: if in decline process, force value is in prescribed limit, and force value is without significant change, then jack is qualified；If force value exceedes setting, but without significant change, then the assembling of jack sealing member is bad；If force value has jumping phenomenon, then jack cylinder linearity is bad；
(3) when under jack load, operating cyloinder expanding-contracting action: if the ascending amount of loading cylinders of operation is more than setting, operating cyloinder in bouncing back near position after, its operation force value is shown near zero value, then jack is qualified；If the rising of loading cylinders does not reach setting, then jack pump core oil suction fault or limit for tonnage valve setting value are too low；If operation force value display pressurized numerical value, then jack Outlet check valves poor sealing；If operation force value display tension numerical value, then jack inlet port check valve poor sealing；
(4) when locking loading cylinders, operating cyloinder expanding-contracting action: if the power excursion of loading cylinders is within the scope of setting, then jack is qualified；If the minima of force value is less than the lower limit of prescribed limit, then the pressure regulation of jack spring is too low；If the maximum of force value is more than the upper limit of prescribed limit, then the pressure regulation of jack spring is too high；If the super prescribed limit of the amplitude of excursion, then jack spring rate is excessive.
The present invention is compared with prior art, have the following advantages and effect: test machine utilizes hydraulic pressure, sensing and information technology, the data of inspection jack gained can be identified judgement automatically, except providing check conclusion, moreover it is possible to analyze and draw its common concrete failure cause.
