Problems solved by technology

[0004] In many applications, due to the limitations of use conditions and actual construction technology, the weighing platform cannot work horizontally
For example, due to the geographical and topographical constraints of the toll station square site, the road weighing equipment that is widely used at present generally has a large longitudinal slope. cross slope
As a weighing device installed on the road and needs to be in the same plane as the road surface, it cannot be installed horizontally
Moreover, during installation, if the weighing equipment is on the same plane as the ground, that is, inclined to the horizontal plane, the weight on it will generate force decomposition, making the weight data obtained by the weighing equipment inaccurate.

Embodiment 1

[0023] like figure 1 As shown, an electronic weighing instrument suitable for weighing on an inclined plane includes at least one weighing platform 1, and an inclined installation adjustment device is provided on the weighing platform 1. The number of weighing platforms 1 can be set according to actual needs, and can be one, two, four, or more.

[0024] The tilting installation adjustment device means: there are support beams 2 on both sides of the weighing platform 1, each weighing platform 1 is hoisted by the adjustment rod 4 and supported by the support beam 2, and the load cell is set at the fulcrum of the support beam 2 3. The lower parts of both ends of each support beam are fulcrums, that is, load cells 3 are installed.

[0025] An independent ground plate 5 is provided under the load cell 3. For vehicle weighing equipment, the independent ground plate 5 is pre-embedded on the concrete foundation, and the two independent ground plates in the driving direction are on th...

Embodiment 2

[0029] For multiple weighing platforms, in addition to the tilting installation adjustment device installed on each weighing platform 1, a frame 6 and a common ground plate 7 are also provided. The shared ground plate 7 and the independent ground plate 5 are on the same plane and must be installed horizontally , the frame 6 and the road surface are in the same plane, that is, the frame 6 is installed obliquely, so a device is needed to ensure that the inclination of the frame 6 can be freely adjusted when the common ground plate 7 is installed horizontally.

[0030] like figure 1 , Figure 4 As shown, a frame 6 , a common base plate 7 and a universal hinge device 9 are arranged on the periphery of the weighing platform 1 , and the frame 6 and the common base plate 7 are connected through the universal hinge device 9 .

[0031] In this embodiment, the free-hanging inclined installation method refers to: erect at least two weighing platforms 1 along the traveling direction of t...

Abstract

The invention relates to an electronic weighing instrument applicable to inclined-plane weighing. The electronic weighing instrument at least includes a weighing platform. An inclined installation adjustment device is arranged on each weighing platform. Each inclined installation adjustment device is as follows: the two sides of the weighing platform are provided with support beams; the weighing platform is hung on the support beams through adjustment pull rods; and weighing sensors are arranged at support points of the support beams. The invention also provides a free hanging inclined installation method which is implemented to the electronic weighting instrument. At least one weighing platform is arranged in an object moving direction and the support beams are horizontally installed at the two sides of each weighing platform, and through adjustment of the adjustment pull rods, the weighing platform is enabled to be leveled with the ground so that the gravity of an object is vertical to the weighing sensors. The electronic weighing instrument is capable of truly reflecting the gravity of the object under a condition that the weighting platform is inclined so that accuracy demands of grade-I dynamic accuracy of GB / T21296-2008 and JJ907-2007 are met.

Description

technical field [0001] The invention relates to an electronic scale suitable for weighing on an inclined plane and a free-suspension inclined installation method thereof, which can be widely used in the fields of road weighing equipment, conveyor belt inclined plane weighing, and the like. Background technique [0002] The working principle of electronic weighing instruments is mostly by measuring the gravity of heavy objects, and converting it into mass according to the local acceleration of gravity. The direction of gravity is vertically downward and perpendicular to the horizontal plane. Therefore, usually, the weighing platform is installed on the horizontal ground, and a weighing platform parallel to the horizontal plane is supported by one or more load cells. (Also known as weighing platform). [0003] Its working principle can be described as, placing the heavy object on a horizontal weighing platform, and the weighing platform transmits the gravity of the heavy obje...
