とは逆の手順にておこなう。In this device, the support base is adjusted to a predetermined height on the carriage, the guide frame is inserted into the furnace, the rotating pin rod attached to the chute to be removed is brought into contact with the seat, and the load of the chute is applied to the guide frame. To move. On the other hand, the holding guide is tilted by remote control and applied to the chute to hold it.Then, the joint part on the upper part of the chute is separated, and the removed chute is rotated around the rotating pin rod as a shaft to lie down on the guide frame and out of the furnace. Take out. When mounting, follow the procedure reverse to the above.
本考案の一実施例を図面に基づいて説明する。 An embodiment of the present invention will be described with reference to the drawings.

イド７が取付けられている。FIG. 1 is a side view showing the structure of a chute changing device and its usage state. 1 is a trolley, which can run on a guide rail 13 installed on a frame 12 extending outside the furnace of the blast furnace 11 toward the core direction. Reference numeral 2 is a driving device for traveling. A support base 3 which is movable up and down by hydraulic jacks 3a and 3b installed at the front and rear parts of the carriage is mounted on the carriage 1, and the side of the support base 3 facing the furnace body is extended by an appropriate length to guide frame. 4 is forming. A pair of left and right semicircular receiving seats 5 are provided at the tip end of the guide frame 4, and a chute which can be tilted up and down by a hydraulic cylinder 6 shown in FIG. The holding guide 7 is attached.

にて作業をおこなう。When the chute is replaced with this device, the work hole 14 of the blast furnace 11 is first opened, and the support base 3 is moved up and down by the hydraulic jacks 3a and 3b so that the guide frame 4 is moved. It is inserted into the furnace at a predetermined working height and adjusted so that it is horizontal. A pin rod 16 is horizontally attached to the chute 15 to be removed in advance near the center of gravity thereof, and the receiving seat 5 of the inserted guide frame 4 is attached thereto.
While the load of the chute 15 is gradually moved to the guide frame 4 by engaging with the pin rod 16, the hydraulic cylinder 6 is simultaneously remotely operated to stand up the holding guide 7 and apply it to the chute 15. Hold. After that, the joint 15a on the upper part of the chute is separated, and the chute 15 removed while tilting the holding guide 7 is rotated about the pin rod 16 so that the chute 15 lies sideways on the guide frame 4, and then the trolley 1 is operated to operate the entire device. Take the drawer chute 15 out of the furnace.
When installing a new chute, perform the procedure in the reverse order of the above.
