Further, described hydraulic cylinder is the hollow hydraulic cylinder, and hollow position is bolt hole.
Further, described hollow hydraulic cylinder upper surface is provided with the adjustment pad.
Further, described two hydraulic cylinders are symmetrical set along center line.
Further, be provided with alignment pin between described hydraulic cylinder and connecting key parent.
Further, describedly mill out the cell body corresponding with above-mentioned connecting key parent on ring flange, and go out through hole in the hydraulic cylinder in a side milling of ring flange, connecting key parent correspondence is put into the ring flange cell body, then the ring flange of the other end is bolted;
In the time of need to opening fast, with the disassembling bolts on ring flange, by pipeline, hydraulic quick coupling, reversal valve and pumping plant, pump oil, utilize the outside expansionary force of hydraulic cylinder, thereby two ring flanges opened in the hydraulic cylinder.
Further, all be milled with the cell body corresponding with the connecting key parent on the ring flange at described two ends.
Further, the degree of depth of each cell body is half of connecting key parent.
Beneficial effect of the present invention shows:
This opens large-scale coupling flange dish device soon, mainly comprise connecting key parent and hydraulic cylinder, hydraulic quick coupling, reversal valve and hydraulic power unit, hydraulic cylinder is positioned at connecting key parent two ends, controls stretching out of hydraulic cylinder by reversal valve and retracts and reach the purpose that opens ring flange at the inner directly fast open of coupling flange dish.
Device is symmetrical in strict accordance with the left and right center line, the dynamic balancing of coupling equipment when guaranteeing High Rotation Speed.
Described hollow hydraulic cylinder is provided with the adjustment pad, reaches by adjusting pad the purpose that ring flange is opened fully when the hydraulic cylinder overtravel.
It is unique that described alignment pin has guaranteed that hollow hydraulic cylinder and connecting key parent get the position, guarantees that the section position of opening of connecting key parent makes hydraulic quick coupling reliably be connected with the hollow hydraulic cylinder.
According to the principle of active force and reaction force, utilize the hollow hydraulic cylinder to ring flange with pressure, at the resistance of active force greater than ring flange, ring flange will move vertically and expand the rebate location, shaft coupling is opened.
In order to guarantee the continuity of operation, can adjust the height of pad by change, reach and eliminate the gap that the hollow hydraulic cylinder stays because of stroke alteration, thereby realize the continuous purpose of automatically opening.
The invention has the beneficial effects as follows: simple in structure, easy accessibility, tear down capability is strong, connects positioning accuracy high, can self-locking, labor strength is little.The hollow hydraulic cylinder active force that drives by the movable hydraulic pump is large, directly removes operation in coupling flange dish inside, removes continuously fast.Can remove easily diameter different coupling flange dishes.
