China Patent No. 201210306394 discloses the patent that name is called " hydraulic jack proving installation ", without by the test work, the pump core of tested hydraulic jack and pump core actuating mechanism being connected, thereby can alleviate the working strength of testing work, and can to two hydraulic jack, be tested simultaneously, improved efficiency, but also need more manually-operated and analyze judgement, automaticity is low, does not overcome above-mentioned defect of the prior art.
China Patent No. 200910096088 discloses the patent that name is called " load dynamic pretest system for hoisting jack ", by hydraulic system simulation lifting jack dynamic load, automatically record the variation of lifting jack pressure and stroke in elevation process, lifting jack is carried out to prerun, reach and accelerate prerun speed, reduce the effect of labour intensity, but it is monitored load, and be the prerun of a kind of dynamic data record to lifting jack, data are sufficient not, can not carry out identification judgement automatically to the data obtained, also can't analyze common failure cause, do not overcome well above-mentioned defect of the prior art.
The utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and a kind of reasonable in design, detection efficiency is high, automaticity is high, data binding analysis ability is strong multi-functional intelligence hydraulic jack test machine are provided.
The technical scheme in the invention for solving the above technical problem is: this multi-functional intelligence hydraulic jack test machine comprises: hydraulic control system, frame, data acquisition system (DAS) and computing machine, it is characterized in that: operating cyloinder and load oil cylinder are installed on described frame, and operating cyloinder all is connected with hydraulic control system with the load oil cylinder; Displacement transducer one and force cell one are installed on described operating cyloinder, displacement transducer two and force cell two are installed on the load oil cylinder; Described displacement transducer one, displacement transducer two, force cell one and force cell two all are connected with data acquisition system (DAS), and data acquisition system (DAS) is connected with computing machine.Hydraulic control system provides pressure to operating cyloinder and load oil cylinder, and operating cyloinder acts on the handle of lifting jack, simulates manually lever operated; The load oil cylinder acts on the weight bearing area of lifting jack, the fictitious load operating mode; The shift value of displacement transducer one and force cell one measurement operation oil cylinder and power value, displacement transducer two and force cell two are measured shift value and the power value of load oil cylinder; Data acquisition system (DAS) gathers the data of displacement transducer one, displacement transducer two, force cell one and force cell two, and computing machine carries out identification judgement automatically, analyzing failure cause to the data of data acquisition system collection.
Operating cyloinder described in the utility model and load oil cylinder are arranged on the top of frame, and displacement transducer one and force cell one are arranged on the bottom of operating cyloinder, and displacement transducer two and force cell two are arranged on the bottom of load oil cylinder.
During the utility model test, following several situation and analysis result are arranged:
(1) when lifting jack in the position that hoists, at the appointed time, apply permanent load: if lifting jack is qualified in setting value for load oil cylinder decline displacement; If load oil cylinder decline displacement surpasses setting value, operating cyloinder occurs that power value and shift value change, lifting jack outlet retaining valve poor sealing; If load oil cylinder decline displacement surpasses setting value, operating cyloinder power value and shift value are unchanged, jack piston poor sealing or cylinder bottom poor sealing;
(2) when lifting jack in the position that hoists, open oil return valve, the load oil cylinder presses down with constant speed: if in the decline process, the power value is in specialized range, and the power value is without significant change, and lifting jack is qualified; If the power value surpasses setting, but, without significant change, the assembling of lifting jack seal is bad; If the power value has jumping phenomenon, the jack cylinder linearity is bad;
(3), under lifting jack load, the operating cyloinder expanding-contracting action: be greater than setting if operate the ascending amount of a load oil cylinder, operating cyloinder is after bouncing back near meta, and its operating physical force value is presented near zero value, and lifting jack is qualified; If the rising of load oil cylinder does not reach setting, jack pump core oil suction fault or limit for tonnage valve setting value are too low; If the operating physical force value shows pressurized numerical value, lifting jack exports the retaining valve poor sealing; If the operating physical force value shows tension numerical value, lifting jack inlet port retaining valve poor sealing;
(4) when locking load oil cylinder, the operating cyloinder expanding-contracting action: if the power variation range of load oil cylinder in the setting scope, lifting jack is qualified; If the minimum value of power value is less than the lower limit of specialized range, the pressure regulation of lifting jack spring is too low; If the maximal value of power value is greater than the upper limit of specialized range, the pressure regulation of lifting jack spring is too high; If the super specialized range of the amplitude of variation range, the lifting jack spring rate is excessive.
The utility model compared with prior art, have the following advantages and effect: test machine utilizes hydraulic pressure, sensing and infotech, can carry out identification judgement automatically to the data of check lifting jack gained, except providing check conclusion, can also analyze the concrete failure cause that show that it is common.
