Abstract

The invention relates to a safety bolt. The safety bolt comprises a pair of clamping bolt assemblies, a pair of redirection wheel assemblies, a pair of positioning pulley assemblies and a manual bolt,the clamping bolt assemblies are arranged on the front surface of a stand column installing plate, steel wire rope lock catches are arranged on the back face of the stand column installing plate on the clamping bolt assemblies in a protruding mode, the redirection wheel assemblies and the positioning pulley assemblies are arranged on the back surface of the stand column installing plate, the positioning pulley assemblies are arranged under the redirection wheel assemblies, the two redirection wheel assemblies and the two positioning pulley assemblies are located on the same horizontal line, the manual bolt is arranged between the two positioning pulley assemblies, one end of the steel wire rope is fixedly arranged on a steel wire rope lock catch, the other end of the steel wire rope is sequentially sleeved with the redirection wheel assembly and a positioning pulley assembly which are arranged on the same side of the steel wire rope lock catch in a sleeved mode and then is installed in a threading hole of the manual bolt, and the steel wire rope is always in a straightening state between the redirection wheel assembly and the positioning pulley assembly. The safety bolt is simpleand reliable in structure and easy to install and use, and can effectively improve the safety performance of the furnace cover lifting mechanism.

Description

technical field [0001] The invention relates to the technical field of degassing box equipment for molten aluminum refining, and in particular to a safety bolt for locking and preventing falling after the furnace cover of the degassing box is opened and raised to the highest point. Background technique [0002] At present, major manufacturers at home and abroad mostly use online refining and degassing systems for the refining and purification of aluminum melts. Most of the online refining and degassing systems are box-type rotary degassers. Aluminum liquid flows into the degasser box, and the refractory material The lining stays, and a heater is installed in the furnace cover of the box to keep the molten aluminum in a molten state. At the same time, a degassing rotor is set in the furnace cover. The rotating rotor is broken into countless small bubbles, which diffuse and rise in the molten aluminum, thereby removing hydrogen. [0003] When the degasser box is in use, regul...
