Abstract
A discharge gate clamping device for clamping a lower plate of a discharge gate. A pair of torsion bars are mounted on the side of the lower plate each having a respective first end connected to a crank arm, and each torsion bar has a second end carrying a cam. When the crank arm is rotated the torsion bars rotate for rotating the cams which press against a surface for lifting the lower plate upward. Because each cam is mounted on an independent torsion bar, a uniform pressure is applied to the lower plate of the discharge gate.
Claims7
A clamping device for the height-wise elastic clamping of a moveable part of a sliding discharge gate of the type which comprises a first, upper fixed plate fixed to the base of a ladle, a second, lower fixed plate having lateral sides and being spaced from the former but by a distance suitable to receive a third, intermediate slidable plate whose position regulates the amount of opening of the discharged gate, in which are provided a clamping device which thrusts the lower fixed plate against the intermediate slidable plate and hence the latter against the upper fixed plate, characterized by said clamping device comprising in sequence:
- a pair of shafts rotatably supported by the lateral side of the lower fixed plate,
- on the front end of each of said two shafts, a crank arm whose free end is fixed, symmetrically to the other one, to one of the two ends of a floating actuating means for moving said crank arm back and forth,
- on the other end of each of said two shafts, cams whose rotation, fixed to the rotation of the two shafts referred to above, causes the lower fixed plate to approach or move away from the upper fixed plate in a direction perpendicular to the planes of said plates, and
- wherein said two shafts are dimensioned to exhibit torsional flexibility.
