All-fiber trolley-type resistance furnace

Abstract

The utility model discloses a full fibre trolley type resistance furnace belongs to resistance furnace field, including furnace body, closed subassembly and drive mechanism are arranged at the top of furnace body respectively, and drive mechanism is connected with closed subassembly, drive mechanism is used for providing power for closed subassembly, and closed subassembly is used for closing at the furnace mouth place of furnace body, closed subassembly includes two settings in the top of furnace body's stand, rotatable through the stand's rotary bar, two respectively cover set in the outer wall of rotary bar's guide pulley, cover in the outer wall of guide pulley's tow rope, the utility model discloses a full fibre trolley type resistance furnace, compared with prior art, and the full fibre trolley type resistance furnace of this full fibre trolley type resistance furnace sets up wheel speed sensor real -time monitoring door board moving speed, cooperates power mechanism, expansion piece and elastic buffer piece, can trigger buffer mechanism in time when door board is too fast and goes down, effectively avoided the security hidden danger and equipment damage problem that traditional resistance furnace brought because furnace door rapid falling.
