Disc base plate type weighing sensor

Abstract

The invention relates to a weighing sensor, in particular to a disc base plate type weighing sensor, which aims to overcome the shortcoming that an existing weighing sensor is easy to cause loading point repeatability errors during loading, and resolves the technical difficult problem that metering repeatability errors are easy to be caused during supporting due to stress excursion. The disc base plate type weighing sensor can avoid problems of loading point repeatability errors during loading and metering repeatability errors due to stress excursion during supporting, and comprises an elastic body, a strain gauge and a cable. The elastic body is ring-shaped, a bearing portion is arranged surrounding an inner ring on the upper end surface of the elastic body, the section of the upper end surface of the bearing portion is arc-shaped, the strain gauge is attached to the lower end surface of the elastic body, a supporting portion is arranged at the edge of an outer ring on the lower end surface of the elastic body, the lower end surface of the supporting portion is in the shape of a ring surface with a tapered bottom corner, and the cable is connected with the strain gauge via a data line.

Description

Technical field [0001] The invention relates to a weighing sensor, more specifically to a disc pad type weighing sensor in a container crane weighing and measuring system. Background technique [0002] In the new round of international logistics competition, as the world's transportation industry develops towards large-scale and super-large scales, China's five major port clusters are all facing new development opportunities and improvements. In addition to playing the transport function of loading and unloading container ships, the port group will also participate in the organization and business activities of various logistics links and the connection and coordination between each other, gradually becoming a logistics base in the global international trade and transportation system. High and new technology represented by the global electronic data exchange system will become the main means of modern port management, and the competition and cooperation modes of port logistics ar...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem that the existing weighing sensor is prone to repeatability error of the loading point when it is loaded, and the technical problem of repeatability error caused by force offset when it is supported, and provides a When loading, there will be no repeatability error of the loading point, and there will be no repeatability error of measurement due to force offset when supporting the disc pad type load cell

The elastic body is in the shape of a ring, and at the same time, the bearing part surrounds the inner ring of the upper end surface of the elastic body, which enhances the bearing capacity of the bearing part and improves the stability. The highest point of the arc is a good solution to the problem of repeatability error of the loading point when it is loaded. A support part is integrally made at the edge of the outer ring of the lower end surface of the elastic body, and the lower end surface of the support part is in the shape of a bottom-angle taper ring surface. The support point of the elastic body will be used as the support point of the elastic body. Even when the force is shifted, the support point of the elastic body will not change, and it also solves the measurement repetition caused by the force shift when it is supported.
