In-out major shaft for furnace

Abstract

An in-out major shaft for a furnace belongs to the technical field of metallurgical machinery equipment, which comprises a plug, a roller end, a shift fork, a steel pipe, and a cooling water pipe. A joint is arranged at one end of the steel pipe, and the plug, the roller end, and the shift fork are sequentially arranged at the other end thereof; the plug is arranged in the steel pipe; the roller end and the shift fork are sleeved on the steel pipe; the end part of the steel pipe and the roller end are connected through a baffle; the plug comprises a pressure plate, the baffle and a support sleeve; the support sleeve is mounted in the steel pipe, is tightly pressed by the pressure plate and fixedly connected with the steel pipe; two grooves with sizes matched with that of a claw on the shift fork are formed on the roller end; the shift fork is formed by two half parts, and each half part is provided with a spigot and a claw; the shift fork is clamped on the steel pipe and fixedly connected with the steel pipe; the steel pipe and the roller end are connected through a connecting key which is classified as a common standard component; the cooling water pipe is mounted in the central hole of the support sleeve; and two ring-shaped water tanks are arranged on the support sleeve at the periphery of the central hole. The in-out major shaft has the advantages of long service life and convenient manufacture.
