Description
Technical field
The utility model belongs to chemical pipeline repair apparatus technical field, and in particular to a kind of underwater flange centralising device.
Background technology
In Chemical Manufacture, flange connection be apparatus and process pipeline often with connected mode, during production maintenance, it is necessary to every
From or cut-out material when, it is necessary to dismantle flange, due to pipe flange after taking apart due to pipeline from gravity or system stress etc.
, easily there is inconsistent phenomenon in reason, cause bolt hole center away from skew, and time and effort consuming when assembling again causes flange to assemble difficult.
Flange aligning method common in maintenance repair is mainly with the method for manpower crowbar, to the pipe flange of major diameter, generally uses
Chain block or crane centering, and influenceed by factors such as environment, spaces, installation effectiveness is low, and there is unsafe factor.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and one kind for providing can easily and quickly to method
Orchid carries out centering, the underwater flange centralising device realized flange Fast Installation, improve operating efficiency.
What the utility model was realized in：A kind of underwater flange centralising device, including sliding seat, it is characterised in that：Institute
Chute is provided with the sliding seat stated, the one side of sliding seat is provided with long through-hole, and the another side of sliding seat is provided with pressing plate,
Top board is provided with above sliding seat, screwed hole is provided with top board, be provided with alignment pin in screwed hole, sliding seat it is upper
Face is provided with lower platen, and regulating bolt is provided with lower platen, and sliding block is provided with sliding seat, and hand-held hydraulic pressure is provided with sliding block
Cylinder, the front end of hand-held hydraulic cylinder is provided with joint.
Described chute is provided in the groove of sliding seat side, and chute matches with sliding block size.
Described alignment pin upper end is provided with screw thread, and the top of alignment pin sets fluted.
Described joint rear end is provided with screwed hole, and joint front end is provided with the jacking block of crescent.
Compared with prior art, the beneficial effects of the utility model are：When in use according to the big of flange screwing aperture
It is small to choose suitable alignment pin, alignment pin is adjusted to after correct position in the screwed hole for penetrate into any one flange, then
The position of hand-held hydraulic cylinder is adjusted, regulating bolt is locked after adjustment position, operate hand-held hydraulic cylinder to stretch out piston rod, until living
Another end face of flange of junction contacts of stopper rod front end, continues to stretch out hand-held hydraulic cylinder piston rod, and flange is pulled by alignment pin,
Make flange that relative displacement to occur, so as to reach the purpose of centering flange, the utility model can be selected according to the difference in flange aperture
Select the alignment pin diameter of different size, big using scope, joint front end is crescent shape, to bump joint of different sizes and its all
It is two lines contact, contact stabilization is good, the utility model simple structure, it is easy to process can be used the flange with different size,
It is time saving and energy saving during flange centering using hand-held hydraulic cylinder.
