Description
The utility model relates to a kind of weighing apparatus counterweight caliberating device, particularly relates to a kind of big quality counterweight caliberating device.
As everyone knows, up to this point in seven basic measurement units that legal system metering tissue is announced in the world, have only quality to adopt the comparison way to carry out transmission of quantity value by the benchmark prototype.Current China to the used big quality counterweight of commercial wide range large-scale weighing machine commonly used 20kg arranged, 25kg, 500kg, four kinds of 1000kg generally adopt third-class standard test weight on the Pyatyi balance, to the demarcation of comparing of fourth class counterweight, because the sensitivity of balance is higher, the staking-out work amount is big, and is time-consuming, effort, labour intensity is big.The purpose of this utility model is to overcome above-mentioned shortcoming, adopts electromechanical integrated device to realize big quality counterweight is demarcated.
The technical solution of the utility model is: a kind of big quality counterweight caliberating device, contain support, suspension gear, suspension gear by sensor, spring, standard test weight lay the dish and counterweight to be marked lay the dish form, sensor one end is fixed on below the crossbeam of support, the other end joins by joint and spring, and the spring other end is laid dish by hanging beam and standard test weight and joined, and lays dish by hanging beam and counterweight to be marked and join.
Support rectangular frame structure, there is crossbeam the upper end, and left and right respectively have a vertical beam, and longeron and oblique buttress brace are arranged at the vertical beam bottom.
Spring can be single spring or two, three, or three above groups of springs, and a level, relocatable cantilever counterweight support beam respectively are equipped with in the left and right vertical beam of the support inboard below standard test weight is laid dish.
Support by three entad in same plane each other angle be 120 ° cantilever beams and corresponding with it three affixed forming of vertical beam that are fixed on the circular bottom plate.
The sensor of suspension gear upper end is fixed on below the cantilever beams of support, the lower end connects spring, the spring lower end connects horizontal hanging beam, laterally the hanging beam other end is connected with vertical hanging beam, the installation code counterweight is laid dish in vertical same plane, hanging beam lower end, and installation remains to be marked counterweight and lays dish in same plane, vertical hanging beam upper end.
Below laying disk center, standard test weight have a liftable to be fixed on vertical counterweight support beam in the bracket bottom disk center.
