In alternate setting, dint wheel 3 is mounted in the cantilever force sensor beam 1 with 1 fixed connection end of cantilever force sensor beam away from pedestal 2
On, cantilever force sensor beam lower face is stretched out in the lower end of dint wheel 3, pedestal 2 under 1 fixed connection end of cantilever force sensor beam
Portion is connected with the stitch 4 that cantilever force sensor beam lower face is stretched out in lower end, the output terminal and secondary meter of cantilever force sensor beam 1
11 input terminal is connected, and forms the real-time monitoring of structures of dint wheel payload.
To ensure using effect, 4 upper end of stitch is connected with adjusting screw rod 13, pedestal 2 and cantilever force sensor beam 1
Be fixedly connected part be provided with 13 corresponding stitch height adjusting holes 14 of adjusting screw rod, 13 spinning of adjusting screw rod is in stitch height
It spends in adjustment hole 14, rotates adjusting screw rod 13, stitch 4 is axially moved up and down along stitch height adjusting holes, is formed stitch lower end and is stretched
Go out the height adjusting structure of cantilever force sensor beam lower surface；
The stitch height adjusting holes 14 are the through hole of up/down perforation, and 13 top of adjusting screw rod is provided with the word for rotation
Slot 13a.
The cantilever force sensor beam 1 includes the first cantilever force sensor beam 1a and for being arranged on 2 lower section both sides of pedestal
Two cantilever force sensor beam 1b, the first cantilever force sensor beam 1a and second cantilever force sensor beam 1b one end link together simultaneously
It is fixedly connected with one end of pedestal, forms the fixed connection end 2a of pedestal 2 and cantilever force sensor beam 1, away from fixed connection end
Between the first cantilever force sensor beam 1a of 2a and the second cantilever force sensor beam 1b screw is mounted in equipped with screw 5, dint wheel 3
On, the lower surface of cantilever force sensor beam is stretched out in the lower end of dint wheel 3, and stitch 4 has 2, is separately positioned on fixed connection end 2a
The first cantilever force sensor beam 1a and the second cantilever force sensor beam 1b bottom.
Out splice going splice 7 is provided on the cantilever force sensor beam 1, is equipped on out splice going splice 7 and is connected with secondary meter 11
Connecting line 10.
There is the jackscrew 8 stretched out upwards on the cantilever force sensor beam 1, jackscrew 8 is located at the outstanding of dint wheel place end
The top of arm force sensor beam, the upper end of jackscrew 8 and the lower face of pedestal are in alternate setting, for preventing shaking in transportational process
