Abstract

The invention discloses a ferroalloy electric furnace electrode internal contracting brake apparatus. Three internal contracting brake bodies are connected in an end-to-end mode with hold hoop electrode cylinders, the first internal contracting brake body is hinged to the second internal contracting brake body, the second internal contracting brake body is hinged to the third internal contracting brake body, the first internal contracting brake body and the third internal contracting brake body are connected through a locking mechanism, the locking mechanism comprises connection plates, a bolt and nut assembly and springs, the connection plates are respectively arranged on opposite connection end surfaces of the first internal contracting brake body and the third internal contracting brake body, bolts penetrate from the connection plate of the first internal contracting brake body to the connection plate of the internal contracting brake body, and at one side of the third internal contracting brake body, the springs are sleeved on the bolts and are press-mounted between nuts and the connection plates at corresponding sides; and the end portion of the first internal contracting brake body is provided with an ejection oil cylinder, and the piston rod of the ejection oil cylinder passes through the connection plate of the first internal contracting brake body to abut against the connection plate of the third internal contracting brake body. According to the invention, the structure of a conventional internal contracting brake apparatus is substantially simplified, fault points are reduced, and the investment is decreased by more than 50%.

Description

technical field [0001] The invention relates to an electrical device, in particular to a brake device for an electrode of an iron alloy electric furnace. Background technique [0002] The traditional electric furnace electrode brake device is composed of a fixed external frame and four movable brake bodies. The four movable brake bodies are equipped with oil cylinders and springs, which respectively push against the electrode cylinder and play the role of holding the electrode tightly. [0003] Existing problems: The traditional electric furnace electrode brake device needs to fix the external frame, four brake bodies, and four oil cylinders. The device structure is complex and there are many failure points. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to propose a brake device for the electrode of an iron alloy electric furnace with a simple and compact structure. [0005] T...
