Chinese invention patent CN201110447098.1 discloses a kind of calibrating structure of large-scale weighing machine.Comprise at least consistent with the LOAD CELLS quantity of tested weighing apparatus calibrating unit and for supporting the basis of each calibrating unit, described basis is provided with one for the foundation ditch of accommodating tested weighing apparatus, and the basis of these foundation ditch both sides is respectively arranged with basic embedded board; Often this calibrating unit all comprise one be fixed on base on basic embedded board, the power cylinder, that adds that a centering is arranged on a bearing plate is positioned over bulb briquetting on this force snesor containing the semi-girder of stiff end and free end, a force snesor and a centering, described bearing plate is placed on the weighing platform of tested weighing apparatus, described force snesor adds on the piston of power cylinder with adding power cylinder centering and be located at this, the stiff end of described semi-girder is fixed on base, and the free end of this semi-girder to be positioned at above bulb pressure-bearing pad and to contact with this bulb pressure-bearing pad.
The wherein bending structure that is formed in one of cantilever beam structure, its stiff end is fixed on base by several king-bolt, and base is fixed on basis.When needs work, semi-girder is installed at every turn, all will twists several king-bolt and fix semi-girder, waste time and energy.
Wherein bearing plate is placed on the weighing platform of tested weighing apparatus, and add power cylinder, force snesor and bulb briquetting on bearing plate all need centering to arrange, and semi-girder distortion can make sensor be subject to bias, tilting load thus have influence on sensor measurement accuracy.
[summary of the invention]
Technical problem to be solved in the utility model be to provide a kind of structure simple, install fast and measure the large-scale weighing machine calibrating installation accurately with beam type force snesor.
The utility model is achieved in that
There is the large-scale weighing machine calibrating installation of beam type force snesor, comprising at least consistent with the LOAD CELLS quantity of tested weighing apparatus calibrating unit and for supporting the basis of each calibrating unit, described basis is provided with one for the foundation ditch of accommodating tested weighing apparatus; Often this calibrating unit all comprises a centering and is arranged at a bearing plate adds power cylinder, a beam type force snesor; Described bearing plate is placed on the weighing platform of tested weighing apparatus; Described basis is fixed a pier; One end of described beam type force snesor is connected on described pier by a buckle structure, adds on the piston of power cylinder described in the other end is positioned at.
Described buckle structure is arranged on a sidewall of described pier, and described buckle structure comprises a upper plate, a lower plate, a top board, described lower plate has fluted, and described upper plate has hollow bulb; Snap in bottom described beam type force snesor in the groove in lower plate, described top board inserts the hollow bulb of described upper plate, and described beam type force snesor top and described top board abut against.
The utility model has the advantage of: 1, pier is connected with basis, beam type force snesor directly injects pier, and it is extremely convenient to install.2, one-piece construction is simple, compact.3, one end of beam type force snesor is fixed, and the other end is directly stressed, and before can overcoming, column type sensor adds the drawback of semi-girder constraint by eccentric tilting load.
[accompanying drawing explanation]
