Problems solved by technology

Although it can be repaired and used, its reliability cannot be confirmed; and since there is no suitable detection device for such spare parts after repair, there is no test condition on site
Therefore, when the crane is used online, there is a risk of unreliable operation and a greater safety hazard

Abstract

The invention discloses a crane electric control equipment detection platform. The working modes of a lifting mechanism system comprise four modes in which a lifting motor stator voltage regulating device works, a lifting motor frequency converter works, a to-be-detected lifting motor stator voltage regulating device works, and a to-be-detected lifting motor frequency converter works; and the working modes of the lifting mechanism system are switched through a hoisting console in a control mechanism. The invention further discloses a detection method of the detection platform. By adopting the above technical schemes, line connection is carried out through connector interfaces on the test bench, electric control equipment needing to be detected and spare parts to be detected are automatically switched into an electric control screen, and on-line on-load detection is carried out on the electric control equipment and the spare parts to be detected, so that the detection effect is more accurate, reliable, real and effective, and the safety, stability and reliability are ensured; and various detection modes such as lifting, large vehicle detection and small vehicle detection can be easily switched, so that the platform is more convenient and rapid, and has very high practical value and popularization and application prospects.

Description

technical field [0001] The invention belongs to the technical field of the detection field of electric control equipment of hoisting and transporting machinery. More specifically, the invention relates to a testing platform for crane electric control equipment. The invention also relates to a detection method of the detection platform. Background technique [0002] In the prior art, the electrical control equipment commonly used in cranes is controlled by thyristor stator voltage regulating devices and frequency converters. These electrical control equipment are highly integrated and can only be replaced as a whole if they fail. Although it can be repaired and used, its reliability cannot be confirmed; and since there is no suitable detection device for such spare parts after repair, there is no test condition on site. Therefore, when the crane is used online, there is a risk of unreliable operation and a greater safety hazard. [0003] Therefore, improving the detection ...
