[specific embodiment]
Refer to Figure of description 1 to shown in accompanying drawing 5, the utility model is a kind of novel flange quick-locking device, can be connected with preventer, casing head, it is formed by a few part assembly such as body 1, clip body 2, hydraulic cylinder 3, piston plate 4, piston rod lock shaft 6 and fluid cylinder bolts 7.
Wherein, between described body 1 and clip body 2, by some fixture blocks 8, be connected.And in being also provided with between described body 1 and clip body 2, be connected steel ring 9, further to strengthen combination and sealing between the two.Further, in described body 1, be provided with some grooves 13, described fixture block 8 is positioned in groove 13.
Described body 1 surrounding is provided with some horizontal hole slots 10, in each horizontal hole slot 10, is provided with a piston rod 11.Described piston rod 11 one end are connected on fixture block 8, and the other end is connected with piston plate 4, by described piston plate 4, promote piston rod 11, and piston rod 11 promotes fixture block 8 again, makes body 1 and 2 combinations of clip body.This piston rod 11 adopts transverse hydraulic to drive described fixture block;
Described piston rod lock shaft 6 is through hydraulic cylinder 3 and insert piston rod 11, and itself and piston rod 11 screw by screw thread.
Described piston plate 4 is placed in hydraulic cylinder 3, and is promoted by hydraulic oil.Described hydraulic cylinder 3 is connected on the cylindrical of body 1 by fluid cylinder bolt 7.
On described body 1 and hydraulic cylinder 3, be respectively equipped with a hydraulic pressure oil duct 12, this two hydraulic pressure oil duct 12 is positioned at the not homonymy of piston plate 4.
