    The invention relates to a measurement technique, in particular, to devices for measuring the length of an electrode in an electric furnace.
    The purpose of the invention is to increase the measurement accuracy.
    Figo shows a device for measuring length, side view; Fig 2 shows the device wheels about
    The device comprises a carriage, the frame 1 of which is fixed on the wheels, the chain feed mechanism 2 mounted on the frame 1 by means of a hinge. On the chain fed mechanism 2 is installed with the possibility of reciprocating movement of the carriage 4o
    The supporting guide is made integral, one of its part 5 is mounted on the carriage 4, and its friend. Part 6 is rigidly fixed to the end of the body of the feeding mechanism 2 "Through both parts 5 and 6 supporting the guide the measuring rod 7 is omitted, so that it can be made of steel
    The feed angle of the chain feeder 2 can be smoothly adjusted in the vertical direction with the help of a hydraulic cylinder 8 located between the frame 1 and the chain podlencim mechanism; 10 is fixed on the other end of the body of the feeding chain mechanism 2 opposite to the fixed part 6 of the supporting guide rail
    The angle of inclination of the measuring rod 7 can be adjusted by means of an indicator 11 mounted on the housing of the feed chain mechanism 2 "
    The device works as follows
    In the process of measuring, the frame is additionally supported on the furnace 12 by means of the hinge 13. part 6 of the support guide. Movable part supporting

    to the original position manually (as far as possible) in the furnace 12 through the opening 13 in the furnace wall towards the electrode 14. After that, the movable part 5 of the supporting guide is pneumatically compressed until it is closed, and the fixed part 6 remains open 7 is fed into the furnace by means of a chain feeder 2, as soon as part 5 reaches part 6, which is pneumatically closed, and the moving part 5 returns to its original position. Speaking with the lower end of the electrode 14, the movable part 5 again moves towards the stationary part 6. If necessary, this process can be repeated several times.
    The angle of inclination of the measuring rod 7 is adjusted. The measuring angle indicator 11 directly indicates the position of the electrode 16 relative to the bottom of the furnace 12. The supporting guide and chain feed mechanism can be activated by a hydraulic or other actuator.
    To ensure the stability of the measuring device, it can be removed from the wheels and placed on the stops 15 (), and the measuring device can be either mobile or stationary.
