ける電極昇降用マストの落下防止装置。 It is attached to a mast for raising and lowering an electrode in an arc furnace, which is configured to be raised and lowered by winding and unwinding a wire rope that extends along the vertical direction and is hung at the lower end of the wire rope. In a device for preventing a falling mast, a speed detecting device detecting a descending speed of the mast;
a fixed block located on the side of the mast;
The structure includes a wedge driven between the fixed block and the mast, a wedge drive device for driving the wedge, and a control device for controlling the wedge drive device, and the control device controls the lowering of the mast. For lifting and lowering electrodes in an arc furnace, characterized in that the wedge drive device is actuated to drive the wedge when the speed detection device detects that the speed has exceeded a predetermined set value. Mast fall prevention device.
