Problems solved by technology

[0006] 1. When the iron mixer is pouring molten iron, the power is suddenly cut off, and the brake is in a locked state, and the iron mixer cannot return to its position, causing the molten iron to continue to dump
[0007] 2. When an accident occurs, the operator needs to run to the side of the equipment and manually pull up the emergency brake to return the mixed iron furnace
[0008] 3. The return process of the mixed iron furnace is a mechanical action, the mechanical impact is large, and there is no mechanical protection, which is easy to cause damage to the equipment

Embodiment Construction

[0025] The specific embodiments provided by the present invention will be described in detail below.

[0026] Such as figure 1 As shown, an emergency lock limit control device for a mixed iron furnace includes a contactor KM1, and also includes a UPS power supply, an operating handle SGS1, an emergency stop switch SE1, and a master command controller for a mixed iron furnace. The controller includes the front limit position SQ1A of the iron mixing furnace, the dumping position SQ1B of the iron mixing furnace, the original position SQ1E of the iron mixing furnace and the rear limit position SQ1F of the iron mixing furnace.

[0027] The upper end of the main contact of the contactor KM1 is connected to the UPS power supply, and the lower end is connected to the motor coil of the brake of the tilting motor of the mixed iron furnace.

[0028] The lower end of the coil of the contactor KM1 is connected to the N end of the UPS power supply, and the upper end is connected to the L e...

Abstract

The present invention provides a metal mixer event band-type brake limit control device. The device comprises a contact KM1, a UPS, an operation handle SGS1, an emergency stop switch SE1 and a metal mixer master controller. The metal mixer master controller comprises a metal mixer front limitation position SQ1A, a metal mixer inclination position SQ1B, a metal mixer original position SQ1E and a metal mixer rear limitation position SQ1F. The UPS is configured to supply power for a band-type brake and allow the limitation position of the master controller to connect in series with the band-typebrake control loop. When the metal mixer is suddenly lost in power in the inclination process, the UPS supplies power to the band-type brake, the band-type brake is opened through remote operation toallow the metal mixer to perform automatic return. When the metal mixer is returned to an initial original position, the limitation motion is performed, the band-type brake is locked, and the metal mixer generating mechanical shock is avoided.

Description

technical field [0001] The invention relates to the technical field of electric drive control, in particular to an emergency brake limit control device for a mixed iron furnace. Background technique [0002] The mixed iron furnace is an auxiliary steelmaking equipment between the blast furnace and the converter. It is mainly used to adjust and balance the supply and demand of molten iron between the blast furnace and the converter to ensure uninterrupted supply of the molten iron required by the converter. The molten iron is stored in the mixed iron furnace and Mixing molten iron composition and uniform temperature is very beneficial to converter steelmaking. [0003] The main transmission equipment of the mixed iron furnace is the tilting motor, and the master controller is used to control its original position, dumping position and front and rear limit positions, and the brake plays the role of fixing the position. When it is necessary to store the molten iron sent by the...
