Abstract: PURPOSE: To eliminate irregular sludge discharge works or loss of molten metal changed into products by a method wherein a working vehicle is advanced to a specified position in front of a furnace, a sludge removing arm is aligned with a height of furnace port, thereafter the arm is repeated in its predetermined operation pattern in accordance with a predetermined program. CONSTITUTION: In order that a sludge discharge operation is carried out by a working vehicle, pushing-out arms 12, 13 are set to be the shortest state, a slant cylinder 10 is operated to have a horizontal state, the vehicle is stopped at a predetermined position in front of a furnace under a state in which the arms are placed at the lowest position by a lift cylinder 9. The arms are fixed and stabilized with a jack cylinder 4. Arms are lifted up and retracted manually and their position set is completed in compliance with the height of the furnace port.  The arms are once retracted to their shortest lengths and a push button of 'AUTO MATIC START' is depressed, resulting in that the arm 13 may repeat motion patterns of moving forward→descending → retracting → slant ascending → retracting → discharging →advancing by a desired number of times with a scraper 14 being fixed at the extremity end of the arm and then its operation is completed. Speeds in ascending and retracting operations of the scraper 14 are adjusted in response to a slant angle of a furnace wall at the furnace port and then sludge of dross can be removed in compliance with a slant angle at the furnace port.

Title: Curve propulsion device
Inventor: NAKAHARA KENJI
IPC: E21D9/06
Filed: 1994-08-10
Abstract: PURPOSE:To improve workability in propulsion in a multiple curve by installing an elastic thrust transmitting member by layering a plate-like member composed of a hardly deforming construction material and a plate-like member composed of an easily deforming and high stability construction material between propelling pipes. CONSTITUTION:When a curve is constructed, an angle of a shield machine 3 is set by a steering jack D, and thrust is applied to a tail end propulsion pipe 4, and the thrust is forward transmitted in order through respective thrust transmitting members 5. Next, in this case, since both ends of the transmitting members 5 are formed of a second plate-like member 7 composed of rubber or the like, the thrust is dispersed to the whole transmitting members 5, and a trouble such as stress cracking due to excessive concentration of the thrust is not caused. Next, since a plate 7 is automatically elastically deformed, the thrust is transmitted in an optical condition in response to a curve. Since a first plate-like member 6 composed of iron or the like is not deformed, the most approaching distance E of mutual end surfaces of a pipe 4 is secured by a fixed quantity or more. Therefore, a point touch between pipes can be prevented while. coping with the curve, and a device can be also downsized.
