The utility model discloses a rotatable opening support reduces strainometer atress in the installation, reduces the strainometer and damages, solves the support problem of droing, avoids strainometer and electric current contact, and measuring result is guaranteed to obtain smoothly by the inside vibration wire of protection.
Description
Technical field
This utility model relates to a kind of surface strain meter mounting and positioning device, and this device is adapted to engineering monitoring or experiment field of measuring technique.
Background technology
Surface strain meter has been widely used in steel construction or the strain measurement of concrete in engineering and experiment, when existing surface strain meter is installed, first bearing pasted or be welded to object under test surface, distance can be determined by the cylinder model with strain gauge adjoining dimensions, but owing to strain gauge is weak to tension-torsion, it is not amenable to bigger external force, cause that installation process produces strain gauge to damage, the situations such as bearing comes off or reading is inaccurate, strain gauge is directly welded to object under test surface together with bearing by some monitoring personnel, the electric current produced in welding process is by internal for direct failure strain meter vibratory string, above variety of problems brings very big inconvenience to the use of surface strain meter.
Utility model content
This utility model is to install and use the problem that strain gauge is damaged, bearing comes off and reading is inaccurate present in process, utility model one surface strain meter erection support to solve surface strain meter.
The technical solution adopted in the utility model is a kind of surface strain meter mounting and positioning device, this device includes the first bearing 1, second bearing 2, it is provided with the first preformed hole 3 in the middle of first bearing 1, the end of thread of strain gauge is passed from the first preformed hole 3 and is fixed by nut, second bearing 2 is divided into upper and lower two parts and sets the second preformed hole 4 in centre, two parts are connect by the axle 5 of end up and down, the top of the second bearing 2 is provided with the first bolt hole 6 and the second bolt hole 7, bolt in first bolt hole 6 is used for fixing strain gauge non-threaded end, bolt in second bolt hole 7 screws in the groove of strain gauge, to limit strain gauge rotation and to move forward and backward, installing mould rod 9 is the cylindrical member equivalently-sized with strain gauge, the determination of position when pasting for bearing or weld.
The implementation process of this device is as follows, is first arranged on by installation mould rod 9 in first bearing the 1, second bearing 2, on object under test behind labelling the first bearing the 1, second bearing 2 position, unloads installation mould rod 9, pastes or weld first bearing the 1, second bearing 2；The end of thread of strain gauge penetrates the first preformed hole 3, and non-threaded end puts into the second preformed hole 4 of the second bearing 2 opened；Close the second bearing 2 screw first bolt hole the 6, second bolt hole 7 inner bolt successively, finally screws the nut of the strain gauge end of thread.
Installing the size of mould rod 9 and the adjoining dimensions of strain gauge, its one end is provided with the bolt screw-in in termination groove 8 makes the second bolt hole 7, and the other end is provided with screw thread；Termination groove 8 is corresponding with the groove location of strain gauge.
This utility model uses rotatable opening bearing, reduces strain gauge stress in installation process, reduces strain gauge and damages, and solves bearing and comes off problem, it is to avoid strain gauge and galvanic contact, the internal vibratory string of protection, it is ensured that obtain measurement result smoothly.

Detailed description of the invention
Illustrating this utility model in conjunction with accompanying drawing, accompanying drawing is schematic diagram, the most in a schematic way explanation this utility model basic structure.
Fig. 1-4 illustrates basic composition of the present utility model, first bearing 1 is band preformed hole erection support, second bearing 2 is divided into upper and lower two parts, and fix with axle and bolt respectively on both sides, during use, screw out the first bolt hole 6 inner bolt and open the second bearing 2, put into installation mould rod 9, close the second bearing 2, screw in first bolt hole the 6, second bolt hole 7 inner bolt and adjust installation mould rod position, make the second bolt hole 7 inner bolt head overlap with installation mould rod 9 termination grooves, the more threaded one end of installation mould rod is penetrated the first bearing 1, locked with nut front and back.
The strain gauge fixed is swung on object under test, labelling the first bearing the 1, second bearing 2 position, unclamp the first bearing 1 end nut, second bolt hole the 7, first bolt hole 6 inner bolt successively, take out and mould rod, the mark position that first bearing the 1, second bearing 2 is pasted or is welded on object under test are installed.
Strain gauge one end is penetrated in the first preformed hole 3, the other end is placed in the second preformed hole 4, close the second bearing 2, screw in first bolt hole the 6, second bolt hole 7 inner bolt and adjust strain gauge position, the second bolt hole 7 inner bolt head is made to overlap with strain gauge termination groove, nut before and after locked first preformed hole 3 internal strain-ga(u)ge unit one end.
