Abstract
The utility model discloses a force and displacement measuring lifting jack which comprises a sleeve (1) and a lifting shaft (2). The utility model is characterized in that a force measuring sensing device (3) is arranged along the axial direction of the lifting shaft (2), and a displacement measuring sensing device (4) is arranged on the sleeve (1) or the lifting shaft (2). The lifting jack is a force and displacement measuring lifting jack which is capable of measuring the lifting force and the axial displacement amount of the lifting jack.
Description
Technical field
The utility model relates to a kind of jack.
Background technology
Jack has been widely used in fields such as engineering, machinery, scientific experimentation, but the mechanical jack that uses at present scarcely is with device for measuring force, can't measure top lift.The hydraulic jack dynamometry be the conversion pressure by hydraulic circuit draw jack stressed size, and hysterisis error is too big, so this mode can only be done unidirectional accurate measurement, moreover, because the influence of factors such as hydraulic efficiency pressure system leakage makes observed reading inaccurate usually.The jack that uses does not have top lift or stroke measuring device at present, can't measure jacking stroke and stressed, so measure at needs under the state of top lift or jacking stroke, the jack that uses all can't reach requirement at present.
The utility model content
The technical problems to be solved in the utility model provides a kind of dynamometry and the location that can measure the top lift of jack and moves jack.
For solving above-mentioned technical matters, the utility model adopts following scheme.
A kind of dynamometry and location move jack, comprise sleeve, and apical axis axially is provided with the force-measuring sensing device along described apical axis.
Described sleeve or apical axis are provided with location and move sensing device.
Described force-measuring sensing device is steel chord type sensor, optical fiber sensor, strain-gauge transducer or piezomagnetic sensor.
Dynamometry of the present utility model and location move jack, by the apical axis along jack force transducer are set axially, have realized jack jacking force measurement; Move sensing device by the location that is arranged on sleeve or the apical axis, realized measurement relative displacement between sleeve and the apical axis.
The utility model will be further described below in conjunction with specification drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the structural representation of the utility model embodiment two
The specific embodiment
With reference to accompanying drawing, dynamometry and location among the utility model embodiment move jack, comprise sleeve 1, and apical axis 2 is characterized in that, adorn 3 along the force-measuring sensing that axially is provided with of described apical axis 2, and described sleeve 1 or apical axis 2 are provided with location and move sensing device 4.
Embodiment one
In the present embodiment, jack is solid jack, and force-measuring sensing is adorned 3 and is installed in the axial of apical axis 2, is used to measure the top lift of jack, and location moves sensing device 4 and is installed on the sleeve 1, the relative displacement of apical axis and sleeve when being used for measuring jack work.
Embodiment two
Present embodiment two is that with the difference of embodiment one jack is the punching jack.
According to concrete embodiment difference, force-measuring sensing device 3 can be steel chord type sensor, optical fiber sensor, strain-gauge transducer or piezomagnetic sensor.And for the demonstration of power of measuring and displacement, can realize that prior art is very ripe, just tired stating here by exterior display device.
Claims (3)
1. dynamometry and location move jack, comprise sleeve (1), and apical axis (2) is characterized in that, axially are provided with force-measuring sensing device (3) along described apical axis (2).
2. dynamometry as claimed in claim 1 and location move jack, it is characterized in that, described sleeve (1) or apical axis (2) are provided with location and move sensing device (4).
3. dynamometry as claimed in claim 1 and location move jack, it is characterized in that, described force-measuring sensing device (3) is steel chord type sensor, optical fiber sensor, strain-gauge transducer or piezomagnetic sensor.
