Summary of the invention
The present invention is the deficiency existed to solve prior art, provides one to open large-scale coupling flange dish device and the fast extraction of root thereof soon, compared with prior art, has the advantage that labour intensity is little, safety, nothing are damaged.
For achieving the above object, the following technological means of employing of the present invention:
One opens large-scale coupling flange dish device soon, it is characterized in that, comprises connecting key parent, and the two ends of connecting key parent are respectively embedded with a hydraulic cylinder, and hydraulic cylinder is connected with pumping plant by pipeline, hydraulic quick coupling, reversal valve.
Further, described hydraulic cylinder is hollow hydraulic cylinder, and hollow position is bolt hole.
Further, described hollow hydraulic cylinder upper surface is provided with adjustment pad.
Further, two described hydraulic cylinders centrally line are symmetrical set.
Further, alignment pin is provided with between described hydraulic cylinder and connecting key parent.
Further, described mills out the cell body corresponding with above-mentioned connecting key parent on ring flange, and mill out towards the through hole in hydraulic cylinder in the side of ring flange, connecting key parent correspondence is put into ring flange cell body, then the ring flange of the other end is bolted;
When needing to open fast, by the disassembling bolts on ring flange, by pipeline, hydraulic quick coupling, reversal valve and pumping plant, in hydraulic cylinder, pump oil, utilizes the expansionary force that hydraulic cylinder is outside, thus is opened by two ring flanges.
Further, the ring flange at described two ends is all milled with the cell body corresponding with connecting key parent.
Further, the degree of depth of each cell body is the 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, is reached in the inner object of directly opening ring flange fast of coupling flange dish by the retraction of stretching out of reversal valve hydraulic control cylinder.
Device is symmetrical in strict accordance with left and right center line, guarantees the dynamic balancing of coupling equipment during High Rotation Speed.
Described hollow hydraulic cylinder is provided with adjustment pad, reaches the object that ring flange opens completely when hydraulic cylinder overtravel by adjustment pad.
It is unique that described alignment pin ensure that hollow hydraulic cylinder and connecting key parent obtain position, guarantees that the section position of opening of connecting key parent makes hydraulic quick coupling be reliably connected with hollow hydraulic cylinder.
The principle of foundation active force and reaction force, utilize hollow hydraulic cylinder to ring flange with pressure, be greater than the resistance of ring flange at active force, ring flange will move vertically and expand rebate location, and shaft coupling is opened.
In order to ensure the continuity of operation, by changing the height of adjustment pad, reach the gap of eliminating hollow hydraulic cylinder and staying because of stroke alteration, thus realize the continuous object automatically opened.
The invention has the beneficial effects as follows: structure is simple, easy accessibility, tear down capability is strong, connects positioning precision high, can self-locking, and labor strength is little.The hollow hydraulic cylinder active force driven by movable hydraulic pump is large, directly carries out dismounting operation in coupling flange dish inside, removes continuously fast.Diameter different coupling flange dish can be removed easily.
