On the other hand, dodge gate 21 forms the gap that connects the bridge and can compensate gallows 1 and furnace inner wall, before gallows 1 has not descended into furnace, can cover the interval at gallows 1 and furnace edge, makes things convenient for the safe entering of maintainer to overhaul room 2.

In this embodiment, the movable door 21 further includes: and the convex rib is arranged on the inner side of the movable door 21 and is convex towards the interior of the maintenance room 2, and anti-skid lines are formed when the movable door 21 is opened. When the movable door 21 is opened and the maintainer treads the movable door 21 to enter the maintenance room 2, the convex ribs can play a role in increasing friction and preventing skidding. After the movable door 21 is closed, the rib can provide a holding part for the maintainer and also can provide a part for connecting a safety lock for the maintainer.

Wherein the service room 2 comprises: and a safety bar 24 arranged on the inner wall of the maintenance room 2. The safety bar 24 can provide the position of holding temporarily for the maintainer, can provide the connection position of safety rope simultaneously for the maintainer, for the operation safety insurance driving of maintainer.

In this embodiment, the service room 2 further includes: the illuminating lamp 25 is arranged on the overhaul room 2, and the illuminating lamp 25 faces towards the inner wall of the hearth and/or is arranged in the overhaul room 2. The number of the illumination lamps 25 is plural, and the plural illumination lamps 25 have independent trigger switches, respectively. The illuminating lamp 25 comprises a lamp holder arranged on the overhaul room 2, and the illuminating lamp 25 is rotatably connected to the lamp holder. The light 25 can provide the illumination to the relative dim space environment in the furnace, can adjust the switch quantity of light 25 according to maintainer's actual demand, can also make the maintainer carry out the illumination inspection of pertinence through rotating light 25.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
