It is bad, it is mounted in pipeline that will cause content leaks amount big, causes waste, environmental pollution.
Utility model content
To solve the above problems, the utility model provides a kind of hydraulic flange expander.
The utility model is achieved through the following technical solutions:
A kind of hydraulic flange expander, the piston top of off-load handwheel, compression bar and the inside installed including hydraulic cylinder and thereon
Bar, the hydraulic cylinder are fixedly arranged at the front end with link block, and the front end both sides of the edge of the link block are each provided with one and its one
Molding clamping plate is hingedly fixed by pin shaft with support force linkage between two clamping plates, which includes central
Diamond shape grappling fixture and upper and lower two diamond shape claws, the piston mandril of the hydraulic cylinder pass through the center of link block and with bar shaped jacking block
It is connected and fixed, the central medial of two clamping plates is arranged in the bar shaped jacking block.
It is further preferred that two clamping plate inner centrals are provided with a sliding slot, the bar shaped jacking block is arranged in cunning
It is slidably connected in slot and with clamping plate.
It is further preferred that the diamond shape claw and diamond shape grappling fixture are symmetrical arranged it and are all made of steel alloy.
It is further preferred that the front end of the bar shaped jacking block is circular arc setting.
It is further preferred that the pin shaft extends to the circlip being provided on one end on the outside of clamping plate for limit.
Compared with prior art, the beneficial effects of the utility model are: originally practical pass through hydraulic drive piston mandril branch
Support force linkage is opened, and flange is agitated by lever principle, carries out the replacement such as flange, gasket, cushion rubber, whole operation process of expansion
More steady time saving and energy saving, the efficiency better quality for replacing sealing ring is again good, is mounted in pipeline and not will cause content leaks, shuts out
Pollution protects environment absolutely.

Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of hydraulic flange expander, the off-load installed including hydraulic cylinder 1 and thereon
The piston mandril 6 of handwheel 2, compression bar 3 and inside, the hydraulic cylinder 1 are fixedly arranged at the front end with link block 4, the front end of the link block 4
Both sides of the edge are each provided with one and its integrally formed clamping plate 5, pass through pin shaft 10 and setting force bar machine between two clamping plates 5
Structure is hingedly fixed, which includes the diamond shape grappling fixture 9 and upper and lower two diamond shape claws 8 in center, the work of the hydraulic cylinder 1
Plug mandril 6 passes through the center of link block 4 and is connected and fixed with bar shaped jacking block 7, and two clamping plates 5 are arranged in the bar shaped jacking block 7
Central medial.
Two 5 inner centrals of clamping plate are provided with a sliding slot 5-1, and the bar shaped jacking block 7 is arranged in sliding slot 5-1
And it is slidably connected with clamping plate 5.
The diamond shape claw 8 and diamond shape grappling fixture 9 are symmetrical arranged it and are all made of steel alloy.
The front end of the bar shaped jacking block 7 is circular arc setting.
The circlip 11 for limit is provided on one end that the pin shaft 10 extends on the outside of clamping plate 5.
Working principle: in use, first by the screw dismounting on pipe flange 12, by the diamond shape of present apparatus support force linkage
It is put into flange gap 13 at the front end of 8 diamond shape grappling fixture 9 of claw, tightens off-load handwheel 2, press the compression bar 3 of hydraulic cylinder 1, it is hydraulic
The piston mandril 6 of cylinder 1 heads on sliding slot 5-1 slides forwards of the bar shaped jacking block 7 between two clamping plates 5, and the sliding slot 5-1 of setting rises
To guiding sliding effect, diamond shape claw 8,9 rear end of diamond shape grappling fixture of distracting force linkage are understood using lever principle bar shaped jacking block 7,
While strutting, the front end of two diamond shape claws 8 and a diamond shape grappling fixture 9 can be strutted outward respectively by flange 12 to extending out
, so that flange gap 13 is become larger, when flange gap 13, which is expanded to, to be enough to take out sealing ring, stops the compression bar for pressing hydraulic cylinder 1
3, sealing ring is taken out to the sealing ring more renewed, slowly loosens off-load handwheel 2, piston mandril 6 can be recycled with bar shaped jacking block 7,
The front end of diamond shape claw 8, diamond shape grappling fixture 9 in power linkage can move inward, and so that the flange gap 13 of flange 12 is become smaller, finally
Power linkage is detached from flange 12, this completes the work of the expansion replacement sealing ring of flange 12, will using lever principle
It is time saving and energy saving that flange struts, and entire process of expansion is more steady, and the efficiency better quality for replacing sealing ring is again good, is mounted on pipeline
In not will cause content leaks, prevent pollution protect environment, diamond shape claw 8, the diamond shape made using long period alloy is grabbed
First 9 can damage, and the circlip 11 on pin shaft 10 is removed and extracts pin shaft 10, be conveniently replaceable diamond shape claw 8 or the water chestnut of damage in this way
Shape grappling fixture 9 is conducive to daily maintenance.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that the present utility model is not limited to the above embodiments, the above embodiments and description only describe this
