ことを特徴とする流体荷役装置等における緊急切
離し装置。 A clamping mechanism in which a plurality of clamps for clamping flanges joined to each other are connected in a flexible manner in one plane by a connecting member, and the clamping mechanism has a locking shaft having a substantially circular cross-sectional shape at the tip. The clamping mechanism has a fastening rod rotatably attached to one end by a first pivot shaft within the bending plane of the clamping mechanism, and a substantially arc-shaped locking groove for locking the locking shaft. a fastening lever rotatably attached to the end of the clamping mechanism by a second pivot within the bending plane of the clamping mechanism; a piston rod is connected to the clamping lever with a connecting pin and attached to the clamping mechanism; A fastening lever with a locking shaft fitted in the groove fixed with a shear pin is rotated in the fastening direction about the second pivot to enter the fastened state, and the fastening lever is rotated in the releasing direction about the second pivot as a fulcrum. and a release cylinder for disengaging the locking shaft of the fastening rod from the locking groove of the fastening lever, and the clamp of the clamping mechanism has an arc shape with a diameter larger than the outer diameter of the flange in the free state. At the same time, the flange is clamped in a state in which the locking rod is bent in accordance with the outer circumference of the flange in the fastened state with respect to the fastening lever, which is rotated in the fastening direction by fitting the locking shaft into the locking groove. In addition, the relationship between the locking shaft and the locking groove is as follows in the fastening preparation state of the fastening rod in which the locking shaft is fitted into the locking groove.
A first straight line connecting the center of the first pivot shaft and the center of the locking shaft, and a second straight line connecting the center of the second pivot shaft and the center of the locking shaft.
The included angle of the straight line is an acute angle, and the end edge of the locking groove on the fastening rod side is set inward of the first straight line. The end edge on the fastening rod side crosses the first straight line and lies outside of the first straight line, and the center of the locking shaft is between the center of the first pivot and the second
An emergency disconnection device for a fluid cargo handling device, etc., characterized in that it is set to extend beyond an extension of a third straight line connecting the center of a pivot and to be inside the extension of the third straight line.
