For the present invention is described in further detail, each module and working principle expansion are described as follows now:
Movable supporting plate 8 is there are two function: 1), constituting the frame of entire measuring device；2), in the load of polished rod lockset 3
It under effect, vertically moves up and down, load force is passed into spring system, spring system is made to obtain different compressions
Deformation；
Fixed support plate 7 is the base support component of entire measuring device.Entire measuring mechanism is fixed on by the component
On hanging rope fixture 1.
The present apparatus is provided with measurement spring 10 in varying numbers according to actual measurement needs.Spring is that measurement pumping unit is quiet
The key mechanism of state and dynamic load.The present apparatus is justJudgement is observed by the compressive deformation situation occurred after spring stress
Pumping unit load condition；
There are two the functions of tubular column shape spring guide rail 9: 1), guaranteeing that axial deformation only occurs when spring bears pressure；2) it, protects
It demonstrate,proves and only generates vertical displacement between movable supporting plate 8 and fixed support plate 7.
Pretension bolt 16 and nut 17 in the present invention is for connecting, fixing movable supporting plate 8, fixed support plate 7 and bullet
Spring mechanism；
The operation logic of entire measuring device is as follows:
When hanging rope fixture 1 moves up and down under the drive of pumping unit horsehead, the present apparatus can will hanging rope fixture 1 up and down
The power of movement passes to polished rod lockset 3, and polished rod lockset 3 will drive sucker rod mechanism below also to pump.?
During sucker rod pumps, the variation of sucker rod load can make the spring mechanism in the present apparatus by different
Active force, so that corresponding compression variation occur.When load increases, movable supporting plate 8 will be moved down, and make spring-compressed；And
When load reduces, movable supporting plate 8 will be moved upwards, spring-relaxation；When movable supporting plate 8 moves up and down, can make and its
The position measurement mandril 12 being connected moves up and down therewith.And it pushes upUp and down motion further through the effect of rocker arm, make rocker arm
The central point of the slide-wire rheostat 15 of the other end does reverse slide operation.To change 15 position signal output end of slide-wire rheostat
Output voltage, to realize detection to compression deformation of the spring amplitude.Position measuring mechanism is using the purpose of rocker structure, can
Suitably to be amplified by the supporting point for changing rocker arm to spring-compressed amplitude, in order to detect measurement.
