Control method of torpedo-type mixed iron vehicle tilting band brake

Abstract

The invention discloses a control method of a torpedo-type mixed iron vehicle tilting band brake. A control program of the control method is composed of functional modules TYCC01-TYCC07; the functional module TYCC01 is an absolute value forming functional module, the functional modules TYCC02 and TYCC04 are numeric comparison functional modules, the functional modules TYCC03 and TYCC05 are pulse generator functional modules, the functional module TYCC06 is an OR gate, and the functional module TYCC07 is an AND gate. By adopting the technical scheme, the situation is avoided that due to poor contact of a butt-joint plug of the mixed iron vehicle tilting band brake, abnormal closing occurs and accordingly causes accidents; the workload of accident rush repair is reduced; the safety of steelmaking production is improved, operators' personal safety and the safety of equipment are ensured, and it is ensured that production is conducted normally and stably; meanwhile, the economic benefits of steel production are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of electrical control of production equipment in the metallurgical industry. More specifically, the present invention relates to a method for controlling the tilting brake of a torpedo-type mixed-rail car. Background technique [0002] For the tilting motor and tilting brake of the torpedo-type mixed iron car, the two are connected to the tilting control plug of the molten iron pouring station through the tilting control socket on the mobile mixed iron car, and are realized by the tilting control system of the mixed iron car at the molten iron pouring station power and control. [0003] Usually, the tilting '1' motor is powered by the frequency converter of the tilting control system of the mixed iron car, and the power supply control method of the tilting brake is: after the tilting motor is continuously powered on for a certain period of time (such as 500 milliseconds), the tilting control system first gi...

Problems solved by technology

[0006] However, due to various reasons, it is often difficult to keep the contact of the tilting brake therein in a good contact state after the docking of the tilting control socket on the mixed iron car and the tilting control plug of the molten iron pouring station, so that during the tilting process of the mixed iron car, Often due to the insufficient power supply voltage of the tilting brake coil, the tilting brake is abnormally closed and the tilting is blocked, resulting in uncontrolled unloading of the molten iron on the mixed iron car, and a large amount of molten iron flowing into the pit of the molten iron backfilling station

[0007] The molten iron in the accident poured into the pit will not only burn or burn the motor of the mixed iron car, the cable of the car body, the reducer of the car body and the wheels, but also burn and deform the steel structure foundation of the car body and the running rails of the mixed iron car in the pit; In addition, the emergency repair work after the accidental molten iron is poured into the pit is huge, and the operation safety hazard of pulling the burned out mixed iron car from the bottom of the tap hole to the hoisting position where the crane can be lifted is very serious, especially in the mixed iron car If there is still a full tank of molten iron, the difficulty and potential safety hazards of on-site repair work will be even greater

[0008] It can be seen from this that if the tilting brake of the mixed iron car is out of control and the tilting is blocked, it will have a serious impact on steelmaking production and personal and equipment safety.
