Description
Technical field
The utility model relates to the tool pressure characteristic detection device, particularly relates to a kind of lifting jack characteristic detection device.
Background technology
Hydraulic jack is mainly used in the support weight, is widely used in multiple industries such as electric power, mine, railroad bridge, shipbuildings in the operations such as equipment installation, top lifting, a dismounting, and its load-bearing capacity is the product quality important indicator.
At present, domestic in the lifting jack context of detection, still adopt one or more methods of testing to detect.The structure of the jack pressure tester of its use is very simple, and it mainly partly forms (structure as shown in Figure 1) by pressure transducer, pressure data display instrument, test board etc.Wherein, pressure transducer 4 is used to respond to the pressure of lifting jack 3; Pressure data display instrument 5 converts the pressure signal that pressure transducer 4 sends to digital signal, is presented on the charactron; Test board 1 is used to lay lifting jack 3.Its test process is: tested lifting jack is placed on the test board suitable parallels 2 on pad below the lifting jack.Shake jack handle (electronic then starter motor), the rising lifting jack is up to allowing lifting jack push up on the pressure transducer.Then continue the rising lifting jack, the pressure that this moment, pressure transducer was subjected to is exactly the pressure of lifting jack output, and this pressure is presented on the pressure data display instrument.Observe the pressure data display instrument, do not test needed rated pressure if pressure reaches lifting jack, that just continues the rising lifting jack, till reaching needed pressure.If reached test pressure, illustrate that lifting jack can export specified pressure, whether observe lifting jack then has oil leakage phenomenon.If shake handle howsoever, lifting jack does not all reach rated pressure, illustrates that lifting jack can not export rated pressure.
In whole test process, the position of lifting jack and pressure transducer is changeless, and the stroke that lifting jack ejects also is changeless, and the data of test also only are the pressure condition that lifting jack can bear under specific stroke.And in the whole stroke of lifting jack, its pressure condition of bearing is just unknown.If want to change ejection stroke, that will change the thickness that is placed in lifting jack lower padding iron 2, and then the lifting jack that raises again, again observe pressure and change, and can only be to choose several travel point to test, and test process be loaded down with trivial details, need repeatedly to raise, reduce lifting jack, particularly testing large lifting jack, labour intensity is very big.
Summary of the invention
The purpose of this utility model is a kind of lifting jack characteristic detection device that can both realize pressure detection under the different strokes that lifting jack ejects of design.
In order to achieve the above object, the utility model adopts following technical solution: a kind of lifting jack characteristic detection device, comprise test board, pressure transducer, support, bracket fixing plate, computer data processing system, the pressure transducer output terminal is connected with the computer data processing system data input pin by data collecting card and interconnecting bus devices for peripheral equipment, it is characterized in that on support, being provided with plate in the activity, on the fixing aprowl plate of pressure transducer, the output shaft of hydraulic constant pressure system is connected with plate in the activity, and hydraulic constant pressure system bearing is fixed on the bracket fixing plate.
During test, pressure transducer is moved to the top of lifting jack, the hydraulic constant pressure system provides a constant compression force to act in the activity on the plate, plate moves on along with ejecting of lifting jack in the activity, pressure transducer flows to computing machine to the actual pressure data of lifting jack test by data collecting card and interconnecting bus devices for peripheral equipment, automatically write down the pressure of lifting jack in whole rising stroke by computing machine and change, realized the purpose that lifting jack can both detect its pressure under the different strokes that eject.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the prior art constructions synoptic diagram.
Fig. 2 is the structural representation of present embodiment.
Embodiment
As shown in Figure 2, present embodiment comprises test board 1, support 8, bracket fixing plate 9, plate 6 in the activity, pressure transducer 4, displacement transducer 11, hydraulic constant pressure system 10, computer data processing system 12, wherein, plate 6 is located on the support 8 in the activity, on the pressure transducer 4 fixing aprowl plates 6, hydraulic constant pressure system 10 bearings are fixed on the bracket fixing plate 9, the output shaft 7 of hydraulic constant pressure system is connected with plate 6 in the activity, displacement transducer 11 is located on the bracket fixing plate 9, and pressure transducer 4 is connected with computer data processing system 12 data input pins by data collecting card and interconnecting bus devices for peripheral equipment (pci bus) with displacement transducer 11 output terminals.
During test, tested lifting jack 3 is placed on the test board 1, and sets required test pressure on computers.Open hydraulic constant pressure system 10, plate 6 moves down in the drive activity of hydraulic constant pressure system, automatically pressure transducer 4 is moved to the top of lifting jack 3, regulate hydraulic pressure constant-voltage system output pressure then, provide a constant compression force to act in the activity on the plate, no matter where the stroke of lifting jack is gone up, and the constant pressure in the assurance activity all the time of hydraulic constant pressure system on the plate is constant.Shake the handle of lifting jack, allow lifting jack eject, in the hydraulic constant pressure system activity plate since ejecting of lifting jack and on move.In the test process, pressure transducer and displacement transducer are tested the actual pressure data and the run-length data of lifting jack respectively, and flow to computing machine by data collecting card and interconnecting bus devices for peripheral equipment (pci bus) and carry out data processing, computing machine will write down the variation of lifting jack pressure and stroke in whole elevation process automatically, simultaneously, utilize the powerful operational performance of computing machine, draw a diagram, generate database, realize the remote data visit.
In sum, the utility model compared with prior art has the following advantages:
1, can test accurately the relation of jack pressurized situation and travel position.
2, can accelerate greatly detection speed, reduce labour intensity.
3, test process is simple, convenient.
4, realize the remote data visit.
