Background technique
Under the situation of rapid economic development, ocean petroleum resources abundant are faced, each major oil companies accelerate exploitation
Paces.Submarine pipeline is the important tool of oil transportation, currently, mainly to rest in external several families big for pipeline connection technology
Company's hand in, China's pipeline connection technology lag become restrict ocean petroleum developing project development bottleneck.If only by
External technology and equipment, not only somewhat expensive, and also the duration is difficult to grasp
It includes underwater connector and its installation tool that submarine pipeline, which connects system,.Underwater connector is mainly used for connection bridging
A kind of fast connecting joint of pipe and underwater equipment manifold, production tree, PLET, PLEM etc. is the important set of underwater bridging system
At part, it still suffers from the bending square that external surge generates while deep ocean work bears internal pressure.To verify underwater connection
The compactness and reliability of device have usually been inspected in land by dedicated test device, and therefore, there is an urgent need to one kind both
Meet proof strength requirement, and economical and practical underwater connector bending torque test device.
Summary of the invention
The purpose of the utility model is to provide a kind of simulated sea bottom operating condition, the test for applying bending square to underwater connector is filled
It sets.
The technical solution of the utility model is:
The utility model includes pedestal, crossbeam, torque oil cylinder, moment of flexure oil cylinder, union (screwed)bonnet (UB, underwater connector, crossbeam set
Cylinder, flange, support, otic placode one, otic placode two, column；Pedestal is square frame-shaped, and the flange at crossbeam sleeve and its top is in crossbeam
Between, and it is integral with beam welding, underwater connector passes through crossbeam sleeve, and union (screwed)bonnet (UB passes through bolt in the upper surface of flange
It is connect with the top of flange, crossbeam sleeve, crossbeam, underwater connector, the bottom of underwater connector passes through on bolt and pedestal
Support connection, two torque oil cylinders are respectively in crossbeam two sides, and "Z"-shaped, the both ends of each torque oil cylinder pass through pin respectively
Axis connection is on two otic placodes one of crossbeam and on two otic placodes of the column of pedestal stretching, two torque oil cylinders of crossbeam two sides
Equidirectional movement applies torque load to underwater connector；Two moment of flexure oil cylinders at the both ends of pedestal, each moment of flexure oil cylinder
Top is connect by the otic placode two of bottom two of pin shaft and crossbeam with crossbeam, and the strut that moment of flexure oil cylinder two sides of the bottom are stretched out leads to respectively
It crosses two U-bolts and nut is connect with pedestal, the moment of flexure cylinder movement at pedestal both ends is contrary, applies to underwater connector
Bending load.
The beneficial effects of the utility model are:
1, the test of underwater connector simulated sea bottom working environment of bearing capacity in actual condition is provided, is seabed
The development of pipeline connection technology provides guarantee.
2, torque oil cylinder achievees the effect that multiple torque with maximum pressure two-way push crossbeam.
