An electronic crane scale automatic detection device

Abstract

The invention discloses an automatic detecting device of an electric hanging scale. The device comprises a hanging mechanism, a mainframe framework, a weight connecting device, a weight loading device, a discrimination threshold detecting device and a weight dismantling device; the discrimination threshold detecting device comprises a discrimination threshold platform and multiple detecting weightautomatic loading mechanisms, the up-and-down movement of a lifting rod is controlled by a discrimination threshold driving motor, and therefore a second weight group can be loaded or unloaded relative to the discrimination threshold platform; a manner of inner and outer ring weight group is adopted by the weight loading system, the height of the weight mechanism is reduced properly, the safety performance is higher, and the loading working efficiency is higher due to simultaneous loading of inner and outer rings. The detection of the automated dismantling of a large large-tonnage weight group of the electric hanging scale can be achieved by the weight dismantling device, the dismantling efficiency of weights is improved, and labor cost is saved. By means of the automatic detecting device, fully-automated detection of the electric hanging scale can be achieved by the arrangement of the hanging mechanism, the weight connecting device, the mainframe framework and the weight loading device.

Description

technical field [0001] The invention relates to the field of metering and weighing, in particular to an automatic detection device for an electronic crane scale. Background technique [0002] At present, the detection of electronic crane scales in our country mainly adopts standard weights or "substitution method". There are many loading points for medium weights, and the traditional weights are large in size, which leads to difficulty in loading weights, great safety hazards, and low detection accuracy; when the "substitution method" is used for detection, the "substitution method" has strict requirements. If you do not pay enough attention to its detection Neglecting its necessary conditions will inevitably cause adverse consequences and bring errors to the test results. At the same time, some manufacturers of electronic crane scales will use a force measuring machine for testing, so that the electronic crane scales shipped out of the factory are too different from the ac...

[0002] At present, the detection of electronic crane scales in our country mainly adopts standard weights or "substitution method". There are many loading points for medium weights, and the traditional weights are large in size, which leads to difficulty in loading weights, great safety hazards, and low detection accuracy; when the "substitution method" is used for detection, the "substitution method" has strict requirements. If you do not pay enough attention to its detection Neglecting the particularity of the necessary conditions will inevitably cause adverse consequences and bring errors to the test results.

At the same time, some manufacturers of electronic crane scales will use a force measuring machine for testing, so that the electronic crane scales shipped out of the factory are too different from the actual working conditions, and there are often various errors, which affect the accuracy of measurement, and cannot be effectively carried out.
