Problems solved by technology

[0003] In the prior art, the blast furnace oscillating launder is braked by electro-hydraulic pusher. If the electro-hydraulic pusher fails due to emergency power failure or other reasons during the molten iron flow, the brake wheel cannot rotate and the swing launder cannot Swinging left and right, eventually leading to a major safety accident of molten iron overflowing

Embodiment Construction

[0026] Next, the technical solutions in the embodiments of the present invention will be apparent from the embodiment of the present invention, and it is clearly described, and it is understood that the described embodiments are merely embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.

[0027] The core of the present invention is to provide a double power brake that separates the brake wheel and the brake wrapper after the electro-pusher failure, avoiding the brake wheel lock, causing the swinging groove to fail to continue to swing the accident that the iron water spilled. Guarantee production safety.

[0028] Please refer to Figure 1 - Figure 4 , figure 1 A structural diagram of a specific embodiment of a dual-active brake provided by the present invention; figure 2 for figure 1 Structure of the dual pow...

Abstract

The invention discloses a dual-power brake. The dual-power brake comprises a base, wherein an electro-hydraulic pusher, a holding device and two parallel supporting arms are arranged on the base, a brake wheel is arranged between the two supporting arms, a brake shoe is arranged at the side, close to the brake wheel, of each supporting arm, the two supporting arms are hinged to the brake arm, and the holding device and the electro-hydraulic pusher are both connected with the brake arm. The dual-power brake further comprises a supporting seat which is fixedly connected with the base, a cam which is rotatably connected with the supporting seat, and a push rod which drives the cam to rotate, wherein an ejector rod of the electro-hydraulic pusher is provided with a sliding groove, and the brake arm is provided with a sliding block clamped and matched with the sliding groove; and the cam abuts against the brake arm, when the lowest point of the cam makes contact with the brake arm, the brake shoe is combined with the brake wheel, and when the highest point of the cam makes contact with the brake arm, the brake shoe is separated from the brake wheel. Therefore, after the electro-hydraulic pusher fails, the brake wheel and the brake shoe can still be separated through the cam structure, so that the situation that molten iron overflows due to the fact that a swing launder cannot swing is avoided, and safe discharging for the molten iron is guaranteed.

Description

Technical field [0001] The present invention relates to the field of blast furnace equipment, and more particularly to a double actor. Background technique [0002] The blast furnace swinging groove is used to introduce the iron water from the blast furnace from the iron tank into the iron tank, and in the process of disconnecting in the iron water, the tilt angle is repeated according to the iron tank liquid level to meet the needs of the change tank. [0003] In the prior art, the blast furnace swinging groove is braked by the electro-hydraulic pusher. If the electro-hydraulic pusher is exposed due to emergency power failure or other cause, the brake wheel cannot be rotated, resulting in the swinging groove Swing left and right, eventually leading to major safety accidents that have spilled in the iron water. [0004] In summary, how to achieve the turn of the brake wheel after the dispensing of the electro-hydraulic pusher is the problem that the problem needs to be solved in ...
