The invention relates to an electric control method for capping of a torpedo car. A remote operation cabinet, a local operation cabinet, manual operation cabinets and an automatic power connection device are included. The manual operation cabinets are mounted at the two sides of the torpedo car. The local operation cabinet is located at one side of the automatic power connection device. Relay control is adopted as electric control of the remote operation cabinet, the local operation cabinet and the manual operation cabinets, and signals are acquired and transmitted through proximity switches.The automatic power connection device is controlled by a PLC. Power connection of the torpedo car is achieved through the automatic power connection device. Implementation of capping and uncapping actions is controlled in the remote operation cabinet. When the automatic power connection device breaks down, manual plugging is adopted, and implementation of the capping and uncapping actions, namelythe cap opening action and the cap closing action, is manually controlled in the manual operation cabinets or the local operation cabinet. By means of the electric control method, the labor burden ofsite operators is reduced; and the operators are prevented from being directly exposed to high-temperature, high-risk and high-dust environments for work, wherein the high risk is caused by splashingof molten iron.
Description
technical field [0001] The invention relates to an electrical control method, in particular to an electrical control method for adding a cover to a mixed iron car. Background technique [0002] After the mixed iron car is covered, before the mixed iron car is subjected to molten iron or dumped, it is necessary to add and remove the cover to the mixed iron car. Since the mixed iron car does not have its own power supply, it is necessary to provide additional power supply after the insulation and cover device is designed and installed on the mixed iron car; at the same time, the production environment of the mixed iron car is high temperature, high risk (hot metal splashing), high The "three high" dangerous areas of dust are not suitable for manual power connection work, so it is necessary to develop an electrical control for the cover of the mixed iron car for remote automatic operation control to meet production use. Contents of the invention [0003] The present inventio...
