Roller way weighing device

Abstract

The invention discloses a roller way weighing device, which comprises a roller way mechanism and a weighing mechanism installed on a base. An execution mechanism for lifting a roller way is arranged on the roller way mechanism. When the execution mechanism lifts the roller way, the upper surface of the roller way lifts above the weighing mechanism; and, when the execution mechanism lowers the roller way, the upper surface of the roller way is below the weighing mechanism. In the whole weighing process, a weighing sensor, a weighing rack and a receiving bracket of the weighing mechanism do not move; the inclination problem of a weighed object is avoided; the service life of the weighing mechanism is prolonged; furthermore, the weight in every weighing is nearly the net weight of the weighed object; therefore, the weighing accuracy and precision are increased.

Description

Technical field [0001] The invention relates to a weighing device, in particular to a roller table weighing device used in the metallurgical industry and similar industries. Background technique [0002] In the existing roller table scales used in the metallurgical industry, the following schemes are generally adopted: 1. The roller table and the weighing platform of the scale are fixed together, and the roller table and the weighed object are measured together when weighing; 2. The roller table Fixed on the ground, when weighing, the weighing platform of the scale is lifted by a hydraulic device, and then the weighed object is lifted for weighing. In the roller table scale, the roller table generally needs water cooling and power supply, the roller table and the ground are physically connected, and the flow of water in the roller table will affect the weighing; in the first plan, the weight of the roller table and the roller table frame is also affected. Common measurement, and...

AI Technical Summary

Problems solved by technology

In the roller scale, generally the roller table needs water cooling and power supply, the roller table and the ground are physically connected, and the water flowing in the roller table will affect the weighing; in the first scheme, the weight of the roller table and the roller table itself is also taken Common measurement, and this weight may far exceed the weight of the object being weighed, so the first option is difficult to meet the requirements of accurate measurement

And in the first scheme, since the scale frame and the roller table are fixed together, the roller table will rotate and the object to be weighed will vibrate when it passes, which will shorten the service life of the scale

In the second scheme, it is difficult to ensure that the lifting amount of each hydraulic cylinder is consistent during the lifting process of the weighing platform, which will eventually cause the object to be weighed to tilt and affect the measurement
