Summary of the invention
For the technical matters of above-mentioned existence, the invention provides a kind of electronic scales on-line proving device, it can demarcate electronic scales by real-time online, realizes accurately measuring of electronic scales.
The object of the invention is to be achieved through the following technical solutions:
The present invention includes tank body, supporting seat, electronic scales, first hydraulic cylinder, support, counterweight hanger, weight group, flat-bed trailer and contact switch group, described support is framed structure, its four post arranges the first hydraulic cylinder respectively, by the first hydraulic cylinder connecting support seat, tank body is placed on electronic scales by supporting seat, electronic scales is fixed on support, and connect weight group by counterweight hanger, flat-bed trailer is provided with below weight group in support, weight group is supported by the second hydraulic cylinder on flat-bed trailer, contact switch group is placed on flat-bed trailer, wherein contact switch is identical with counterweight quantity, the distance of adjacent two contact switchs is the distance between adjacent two counterweights, second hydraulic cylinder piston end is provided with the contact rack contacted with contact switch.
Further, described weight group comprises multiple counterweight, guide spiro rod, counterweight adjusting pad, is connected, each counterweight is equipped with counterweight adjusting pad between described adjacent two counterweights by least two guide spiro rods.
Described second hydraulic cylinder at least three, is evenly arranged along counterweight periphery further.
Beneficial effect of the present invention is:
The present invention, by hydraulic cylinder jacking liquid container and certified weights, realizes liquid container automatic lifting; Be combined the calibrating of electronic scales with mounting counterweight by contact-making switch, not only structure is simple, easy to use, and demarcation degree of accuracy is high.Can verify electronic scales at any time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.

In figure: 1. the first hydraulic cylinder, 2. support, 21. suspension rods, 3. counterweight, 31. adjusting pads, 32. screw rods, 4. hanger, 5. electronic scales, 6. supporting seat, 7. tank body, 8. flat-bed trailer, 81. second hydraulic cylinders, 82. contact switchs, 83. contact switch framves, 84. contact racks, 9. commutator, 10. pipeline, 11. guide rails.
Embodiment
Below by embodiment and accompanying drawing, the invention will be further described.
Embodiment 1: as shown in Figure 1-Figure 3, the present invention includes tank body 7, supporting seat 6, electronic scales 5, first hydraulic cylinder 1, support 2, counterweight hanger 4, weight group, flat-bed trailer 8, contact switch group, described support 2 is framed structure, its four post is arranged respectively the first hydraulic cylinder 1, by the first hydraulic cylinder 1 connecting support seat 6, tank body 7 is placed on electronic scales 5 by supporting seat 6, electronic scales 5 is fixed on the suspension rod 21 of support 2, and connect weight group by counterweight hanger 4, flat-bed trailer 8 is provided with below weight group in support 1, weight group is supported by the second hydraulic cylinder 81 on flat-bed trailer 8, contact switch group is placed on flat-bed trailer 8, wherein contact switch 82 is identical with counterweight 3 quantity, the distance of adjacent two contact switchs 82 is the distance between adjacent two counterweights 3, second hydraulic cylinder 81 piston end is provided with the contact rack 84 contacted with contact switch 82.Wherein said first hydraulic cylinder 2 can connect computing machine respectively, controls it run by computing machine.Also other control modes can be passed through.
As shown in Figure 3, described weight group comprises multiple counterweight 3, guide spiro rod 32, counterweight adjusting pad 31, is connected, each counterweight 3 is equipped with counterweight adjusting pad 31, in order to adjust the weight of counterweight between described adjacent two counterweights 3 by least two guide spiro rods 32.
Described second hydraulic cylinder 81 at least three, is evenly arranged along counterweight 3 periphery.
The course of work of the present invention:
When in the present invention, electronic scales 5 carries out the accuracy of examining and determine electronic scales 5 before weighing, first control tank body 7 by 4 the first hydraulic cylinders 1 upwards jack-up make tank body 7 not on electronic scales 5, then counterweight 3 school scale is being mounted successively by the second hydraulic cylinder 81 and hanger 4, counterweight hanger 4 is all connected by connecting screw rod 32 with between counterweight 3 and adjacent counterweight 3, mount counterweight 3 so one by one, after electronic scales 5 is calibrated, carry out weighing again.
The present invention can periodic check counterweight, after editing electronic scales 5, can unload the connecting screw rod 32 on counterweight hanger 4, then controls the second hydraulic cylinder 81 and drop to lower dead center and stop.Along its guide rail 11, support 2 is left in flat-bed trailer 8 hauling-out.Need again flat-bed trailer to be dragged in support 2 during verification to carry out verification counterweight again.
The present invention, before scale water, first controls the first hydraulic cylinder 1 jack-up and stops to after top dead center, make tank body 7 jack-up leave electronic scales 5, and the vibration weight of such current does not produce fluctuation and impact to the instrument of electronic scales 5.Then stopped after water filling to scheduled volume in tank body 7 by commutator 9, after the water surface is stable, controls the first hydraulic cylinder 1 and drop to lower dead center, the tank body 7 of splendid attire water is dropped on electronic scales 5.After reading actual numerical value, then tank body 7 is pushed up from electronic scales 5, make tank body 7 not press electronic scales 5, keep the precision of electronic scales 5.
