The working strength of dress personnel improves the installation accuracy of strain gauge.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of installation pedestal of strain gauge includes stent and two Magnetic gauge stands, two Magnetic gauge stand difference
Be connected to the both ends of stent, be provided on the stent for connect fixed strain gauge fixed seat connecting seat, described in two
The direction of Magnetic gauge stand is consistent.
As an improvement of the above technical solution, guide rail is provided on the stent, the both ends of the guide rail are connected to two
Magnetic gauge stand described in the connecting seat sliding connecting base on guide rail, is provided with clamping screw with fixed position on the connecting seat.
As a further improvement of the above technical scheme, the connecting seat is provided with the fixed seat for installing strain gauge
Installing plate, the installing plate are slidably connected to connecting seat, and screw rod is provided on the connecting seat to push installing plate.
It is further improved, the end of the screw rod is connected with handwheel.
It is further improved, ball sliding sleeve is set on the screw rod, the installing plate is mounted on the ball sliding sleeve
On, it is provided with angle-adjusting mechanism between the installing plate and ball sliding sleeve.
It is further improved, the angle-adjusting mechanism includes the screw being fixed on ball sliding sleeve, the installing plate
One end be articulated with ball sliding sleeve, the other end is provided with through-hole and is passed through with screw mandrel, and spring is set on the screw, described
The both ends of spring are connected to ball sliding sleeve, installing plate respectively, and the end of the screw is connected with adjusting nut.
It is further improved, the stent is set as spring steel bar.
The beneficial effects of the invention are as follows：In use, first the fixed seat of strain gauge is mounted on connecting seat, then by two
Magnetic gauge stand is attached to the tested surface of steel construction piece, opens the magnetic switch of two Magnetic gauge stands, and two Magnetic gauge stands generate magnetic force
The tested surface in steel construction piece is adsorbed, so as to which the fixed seat of strain gauge is fixed on the tested surface of steel construction piece, is then being answered
Become on the fixed seat side of meter and apply glue, wait for that the glue solidifies that installment work can be completed, consolidate since Magnetic gauge stand is utilized
Determine strain gauge, installation personnel need not hold strain gauge, and the glue solidifies waiting for, and mitigates working strength significantly, when waiting for that the glue solidifies
The installation of another strain gauge can be carried out, a large amount of activity durations can be saved in this way, an installation personnel can be installed multiple
Strain gauge so that the working efficiency of installation personnel is largely increased.After the glue solidifies, then the magnetic switch pass Magnetic gauge stand
Fall, magnetic force is avoided to generate interference to the sensor gathered data of strain gauge, ensures precision.
