Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
As shown in figs. 1 and 3, present embodiment proposes a kind of load-bearing digital independent equipment of jack 4, including from bottom to top
Pressure sensor group 2, jack 4, second pressure sensor 3 and the upper plate 10 set, the range of pressure sensor group 2 are folded successively
More than the range of second pressure sensor 3, pressure sensor group 2 and second pressure sensor 3 are connected with controller 5, control
Device 5 is connected with instrument 6, and controller 5 is used to select to receive the load-bearing letter that pressure sensor group 2 or second pressure sensor 3 are detected
Number, and control instrument 6 shows to load-bearing data.When jack 4 is applied to pressure sensor group 2 and second pressure sensor 3
Plus power hour, the small second pressure sensor 3 of selection range carries out detection load-bearing data, when jack 4 is to pressure sensor
During the power increase that group 2 and second pressure sensor 3 apply, the big second pressure sensor 3 of selection range is detected, can be made
Obtaining jack 4 can be accurate in the testing result reading in each stage.
Being provided between pressure sensor group 2 and jack 4 in the first supporting plate 7, pressure sensor group 2 includes multiple first
Pressure sensor, first pressure sensor is evenly spaced in around the axis of jack 4.Due to first pressure sensor and
The position of one supporting plate 7 contact is hemispherical contact, if single first pressure sensor is supported to the first supporting plate 7,
The jack 4 for very likely resulting in the top of the first supporting plate 7 is tilted, and overall structure is unstable, therefore pressure in the embodiment
There are three first pressure sensors in sensor group 2, and be evenly spaced in around the axis of jack 4, it is ensured that to first
The stable support of fagging 7 and jack 4.First with 2,4,5 etc. other numbers can be selected as the case may be
The pressure sensor group 2 of pressure sensor.
As shown in Fig. 2 being provided with compressible structure 11 between second pressure sensor 3 and upper plate 10, second pressure is passed
Sensor 3 is by compressing compressible structure 11 after the thrust of jack 4, and close to upper plate 10.Wherein compressible structure 11 is oil cylinder
Or spring.
Set between second pressure sensor 3 and jack 4 and be fixed with least two on second supporting plate 8, upper plate 10
Support column 9 or an annular brace post, support column 9 are distributed in the both sides of second pressure sensor 3, when the second supporting plate 8 and support
During end thereof contacts of the post 9 away from upper plate 10, jack 4 continues to increase the pressure to the second supporting plate 8, and compressible structure 11 is not
It is subjected to displacement again, then second pressure sensor 3 will not sense the change of external force, now the measurement of second pressure sensor 3
As a result it will not change, therefore, controller 5 can control load-bearing data of the second pressure sensor 3 no longer to jack 4 to enter
Row is read.
Second supporting plate 8 includes V-type plate, V-type plate and second pressure sensor on the side of second pressure sensor 3
3 connections, V-type plate is rested on support column 9 by after the thrust of jack 4.Led between V-type plate and support column 9 by guide pillar
To, it is to avoid rocking in moving process.
The lower section of pressure sensor group 2 sets base 1, can keep the stability of the top structure of base 1.
Present embodiment also provides a kind of load-bearing method for reading data of jack, using the load-bearing number of above-mentioned jack
It is read out according to equipment is read, including：
Step one, when jack 4 is smaller to the pressure of pressure sensor group 2 and second pressure sensor 3, controller 5 connects
The detection signal of second pressure sensor 2 is received, and control instrument 6 shows the load-bearing data of jack 4；
Step 2, the pressure increase with jack 4 to pressure sensor group 2 and second pressure sensor 3, when instrument 6
When the load-bearing data of display reach setting value, controller 5 only receives the detection signal of pressure sensor group 2, and control instrument 6 is aobvious
Show the load-bearing data of jack 4.Specifically, when the load-bearing data that instrument 6 is shown reach setting value, the second supporting plate 8 rises to
With end thereof contacts of the support column 9 away from the upper plate 10.
When applying ascending pressure to pressure sensor group 2 and second pressure sensor 3 due to jack 4, use
The pressure sensor of different ranges obtains the accurate load-bearing data in the range of corresponding range, it is to avoid range is used alone
Larger pressure sensor is detected, it is ensured that the accuracy of measurement result.
Note, above are only presently preferred embodiments of the present invention.It will be appreciated by those skilled in the art that the invention is not restricted to here
Specific embodiment, can carry out for a person skilled in the art it is various it is obvious change, readjust and substitute without
Depart from protection scope of the present invention.Therefore, although the present invention is described in further detail by above example, still
The present invention is not limited only to above example, without departing from the inventive concept, can also include that more other are equivalent
Embodiment, and the scope of the present invention is determined by scope of the appended claims.
