Specific 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, support base 6, electronic scale 5, first hydraulic cylinder 1, props up
Frame 2, counterweight hanger 4, counterweight group, flat car 8, contact switch group, described support 2 is frame structure, and its four post is respectively provided with
First hydraulic cylinder 1, by first hydraulic cylinder 1 connecting support seat 6, tank body 7 is placed on electronic scale 5 by support base 6, electronic scale 5
It is fixed on the suspension rod 21 of support 2, and counterweight group is connected by counterweight hanger 4, below counterweight group in support 1, be provided with flat car 8,
Counterweight group is supported by the second hydraulic cylinder 81 on flat car 8, contact switch group is placed on flat car 8, wherein contact switch 82
Identical with counterweight 3 quantity, the distance of adjacent two contact switch 82 is the distance between adjacent two counterweights 3, second hydraulic cylinder 81 piston
End is provided with the contact rack 84 contacting with contact switch 82.Wherein said first hydraulic cylinder 2 can connect computer respectively, leads to
Cross its operation of computer controls.Other control modes can also be passed through.
As shown in figure 3, described counterweight group includes multiple counterweights 3, guide spiro rod 32, counterweight adjusting pad 31, described adjacent two
Connected by least two guide spiro rods 32 between individual counterweight 3, each counterweight 3 is equipped with counterweight adjusting pad 31, in order to adjust weight
The weight of code.
Described second hydraulic cylinder 81 at least three, is evenly arranged along counterweight 3 periphery.
The work process of the present invention：
When electronic scale 5 carries out the accuracy examining and determine electronic scale 5 before weighing in the present invention, control first and tank body 7 is passed through 4
Jack-up makes tank body 7 not on electronic scale 5 to individual first hydraulic cylinder 1 upwards, is then hung successively by second hydraulic cylinder 81 and hanger 4
