Abstract
The utility model relates to a device that utilizes the hydraulic principle to perform the load measurement. The load body of the hydraulic load testing and controlling meter is mounted on the baseboard. A load board is positioned above the load body and an oil cylinder is provided in the load body below the load board. Upper part of the oil cylinder is provided with a piston and the oil cylinder body is provided with a pressure transmitter. Through a pressure sensor in the pressure transmitter, the oil pressure in the oil cylinder is sampled, the structure is reasonable no commissioning is needed. The utility model has the advantages of convenient installation and use, high sensitivity, accurate measuring data, good repeatability, stable and reliable operation and strong ability to resist interference.
Description
Technical field
The utility model relates to a kind of hydraulic principle of using and carries out the device that loading is measured.
Background technology
The sensor of existing loading instrument generally adopts the pressure-strain sheet to sample as electric bridge, and weighing principle is after making deformation of body by gravity, change in response to becoming sheet resistance on the electric bridge, thereby electric bridge has voltage output sense weight.In use, the work of little weighing loading instrument can be said to be normally, but large-tonnage loading instrument then exists problems.Large-tonnage loading instrument work in using now is generally all not too normal, most of loading instrument all are forced to out of service, especially loading instrument (being used for gate the weighs etc.) problem now used of hydraulic department is more outstanding, mainly show weigh inaccurate, serious interference, perhaps do not show, and damage easily, can't normally use.The main cause that causes above-mentioned large-tonnage loading instrument normally not use is the problem of sensor, does not particularly reach on manufacturing process when requiring when sensor, and problem is just more outstanding.Simultaneously, the defective of material also is the one side factor that the problems referred to above occur.
Summary of the invention
The purpose of this utility model is to provide a kind of large-tonnage to weigh data accurately, reliably, the hydraulic pressure loading measurement and control instrument that antijamming capability is strong.
The technical solution of the utility model is as follows: the loading body of hydraulic pressure loading measurement and control instrument is installed on the base plate, loading body top is the loading plate, below the loading plate, be provided with oil cylinder in the loading body, the top of oil cylinder has piston, the oil cylinder body is provided with pressure unit, by the pressure transducer in the pressure unit in-oil cylinder oil pressure is sampled.
Aforesaid hydraulic pressure loading measurement and control instrument, wherein, oil cylinder top is provided with dust cap.
Aforesaid hydraulic pressure loading measurement and control instrument, wherein, pressure unit is communicated with oil cylinder by the oilhole on the oil cylinder.
The utility model has been abandoned the mode of strain-ga(u)ge transducer sampling in the prior art, and adopts present technology maturation pressure survey principle, converts standard signal output after the adopts pressure sensor sampling to.It is rational in infrastructure, need not debug installation, easy to use; Highly sensitive, measurement data is accurate, good reproducibility, and stable and reliable operation, antijamming capability is strong.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Among the figure, 1. loading plate 2. register pins 3. pistons 4. base plates 5. diffused silicon pressure transmitters 6. oilholes 7. dust caps
Embodiment
As shown in the figure, the loading body of hydraulic pressure loading measurement and control instrument is installed on the base plate 4, and loading body top is loading plate 1, locatees by register pin 2 between loading plate 1 and the loading body.Be provided with oil cylinder in the loading body below loading plate 1, the top of oil cylinder has piston 3.Piston 3 is the main bodys of bearing loading, finishes the conversion between weight and the pressure.The oil cylinder body is provided with pressure unit, present embodiment is selected the very ripe diffused silicon pressure transmitter of present technology 5 for use, diffused silicon pressure transmitter 5 is communicated with oil cylinder by the oilhole on the oil cylinder, diffusion silicon pressure sensor in the diffused silicon pressure transmitter 5 is sampled to in-oil cylinder oil pressure, and pressure unit is finished the conversion of pressure and standard signal for Computer Processing.Also be provided with dust cap 7 on oil cylinder top, prevent that dust from entering oil cylinder.
Measuring process of the present utility model is as follows:
1. when weight was born on loading plate 1, this moment, gravity was downward, and weight forwards on the piston 3;
2. on the piston 3 the loading amount has been arranged, gravity is downward, and hydraulic fluid pressure raises in the oil cylinder;
3. the pressure transducer of installing on the oil cylinder can be measured the pressure variation of hydraulic oil in the oil cylinder exactly;
4. pressure transducer is delivered to pressure unit 5 to the data that measure and is changed, and transmitter is sent the 4-20mA standard signal for Computer Processing.
Claims (3)
1. hydraulic pressure loading measurement and control instrument, its loading body is installed on the base plate (4), loading body top is loading plate (1), in loading plate (1) below loading body, be provided with oil cylinder, the top of oil cylinder has piston (3), it is characterized in that: the oil cylinder body is provided with pressure unit (5), by the pressure transducer in the pressure unit (5) in-oil cylinder oil pressure is sampled.
2. hydraulic pressure loading measurement and control instrument as claimed in claim 1 is characterized in that: described oil cylinder top is provided with dust cap (7).
