Double protection control method for upward coiling process of steel coiling vehicle

Abstract

The invention discloses a double protection control method for the upward coiling process of a steel coiling vehicle. An encoder is mounted on a wheel shaft of a wheel of the steel coiling vehicle; a displacement sensor is arranged in a lifting hydraulic cylinder; the specific control process is that a first link is in lifting operation, the lifting displacement of a steel coiling saddle is monitored and the condition that the height of a steel coil central line is in a safety range all the time can be guaranteed; a second link is in the transverse movement process and the drive torque of a travelling drive motor is monitored; any one of the lifting displacement or the drive torque exceeds a prewarning value, a control system sends out an alarm signal, and meanwhile, an execution mechanism stops an action of the lifting hydraulic cylinder or the travelling drive motor. According to the method, a double-protection measure is adopted, so that the normal operation of the upward coiling process is guaranteed, a steel coil is effectively prevented from being collided with a coil barrel, and the normal running of a production line is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of metallurgical rolling, and relates to a double protection control method for the coiling process of a steel coil car. Background technique [0002] Coil wagons are always indispensable in any strip finishing line, whether it is an import facility or an export facility. It can be seen that the application of steel coil cars is indeed very extensive. In order to facilitate handover, steel coil cars usually use saddles or rollers to hold coils. [0003] With the development of metallurgical rolling technology, the requirements for steel coil cars are getting higher and higher. In actual use, because the system pressure may be unstable; the lifting hydraulic cylinder or pipeline leaks; the zero point drift of the steel coil car at the waiting position for a long time, etc., the steel coil car that has completed the height alignment before the winding, the saddle There will always be a slight drop in seat he...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a double protection control method for the coiling process of a steel coil car, which solves the large deviation between the core center line and the coil center line of the uncoiler or coiler in the prior art, resulting in accident problems
