Summary of the invention
The purpose of this utility model is in that for the problems referred to above, a kind of board-like strain transducer extension detecting device is provided, this board-like strain transducer extension detecting device is for the detection of hopper or bin-level, work more reliable and more stable, structure is simpler, and the change of hopper stress can be well adapted to, be greatly improved the service life of bin level detecting device。
The technical scheme realizing above-mentioned purpose is: a kind of board-like strain transducer extension detecting device, include a rectangular slab being vertically arranged and a strain transducer, described rectangular slab side be respectively arranged at two ends with connecting pin up and down, described rectangular slab middle part is provided with a pair rectangular opening of left-right situs, this two rectangular opening forms the bar shaped intermediate connector being positioned in the middle of this rectangular slab on described rectangular slab and lays respectively at the bar shaped edge connector on these rectangular slab both sides, described strain transducer is vertically arranged between the one side middle part of described rectangular slab, this strain transducer is connected across above and below described intermediate connector by being distributed in the connecting bolt at its upper and lower two ends。
Further, the length of described rectangular slab is 4 times to 6 times of described strain transducer length, and the width of described rectangular slab is 2 times to 3 times of described strain transducer width。
Further, the cross section of described edge connector and the cross section of described intermediate connector are equivalently-sized rectangle, and the gauge that length dimension is described rectangular slab of the rectangular cross section of described edge connector, the width dimensions of the rectangular cross section of described intermediate connector is less than the gauge of described rectangular slab。
The beneficial effects of the utility model are:
1, this board-like strain transducer extension detecting device, the length utilizing rectangular slab adds the measurement distance of strain gauge transducer, utilize again stretching and the contractility of rectangular slab intermediate connector, avoid the pair of strain sensors element because deformation is excessive and cause damage, improve job stability and the service life of detecting device；
2, the expanding unit of this board-like strain transducer extension detecting device is easy to adopt the material consistent with detected hopper material, is conducive to the temperature-compensating of detection signal, it is ensured that the degree of accuracy of detection；
3, measured bucket wall deformation signal is expanded by this board-like strain transducer extension detecting device, and by the perception by strain transducer of the deformation signal of this expansion, for the detection of hopper or bin-level, there is simple in construction, feature easy to assembly, that accuracy of detection is high；
4, this utility model is particularly well-suited to the dynamic detection of the bin level of tippler, is simultaneously applicable to other material-level measure with identical function hopper or feed bin。
