[0023] In order to solve the problem of inconvenience in replacing the furnace bottom roller 5, when the furnace bottom roller 5 needs to be replaced, two sets of extension rods 6 can be installed on both sides of the furnace bottom roller 5, and then the first pull rope 9 and the second pull rope 14 can be hung on the arc buckle 8 of the two sets of extension rods 6, and the third pull rope 17 is lifted by the overhead crane. The third pull rope 17, the second electric hoist 16, the second pull rope 14, the two sets of extension rods 6 and the furnace bottom roller 5 can be pulled to one side by the movement of the overhead crane. When the furnace bottom roller 5 moves, the first pull rope 9, the first electric hoist 10, the fixed frame 11 and the pulley 12 on the other side can be moved together, and the fixed frame 11 and the pulley 12 are on the steel beam. When sliding on 13, the moving trajectory of the bottom furnace bottom roller 5 can be limited. When the furnace bottom roller 5 is pulled to one side for a certain distance, the extension rod 6 on one side of the first pull rope 9 can be extended by processing the flange 7, so that a new set of extension rods 6 can be installed through the processing flange 7, and the first pull rope 9 is installed on the arc buckle 8 of the new set of extension rods 6.

Multiple sets of rollers 24 are provided at the end, and the gaps between the multiple sets of rollers 24 can help fix the position of the circular hearth roller 5 until the hearth roller 5 is removed from the quenching furnace body 1. The multiple sets of extension rods 6 can be disassembled by disassembling the processing flange 7, and the bottom block 22 and the placement table 21 are moved obliquely downward by the slope 23 provided on one side of the support platform 3, which is conducive to taking out the hearth roller 5. When the hearth roller 5 is removed from the placement table 21, it is convenient to slide the hearth roller 5 to one side through the multiple sets of cylindrical rollers 24. By providing a top plate 18 on the quenching furnace body 1, it can be adjusted when other hearth rollers 5 need to be disassembled. The position of the steel beam 13 allows the steel beam 13 to move to the furnace bottom roller 5 that needs to be replaced. When the steel beam 13 moves, it can drive the slider 19 at the top to slide in the slide groove, so that when the steel beam 13 moves, it is beneficial to limit the moving trajectory of the steel beam 13 through the slider 19 and the slide groove. By setting a limit rod 20 at the top of the steel beam 13, the limit rod 20 can be driven to one side when the steel beam 13 moves.
