Description
Technical field
The utility model relates to a kind of equipment that type metal expansion joint is entered to torture test and stiffness test.
Background technology
Metal corrugated pipe expansion joint is of paramount importance pressure unit in pressure pipeline element, in various fields widespread uses such as petrochemical complex, thermoelectricity, water power, nuclear power, iron and steel.For this reason, in product approval and the special agreement of contract, all need to check the corrugated tube of type metal expansion joint whether to reach the technical requirement of Design and manufacture by torture test and stiffness test.
At present, domesticly in torture test inspection technology, mainly completed by the specialized equipment of national professional institution, or completed voluntarily under the prison inspection of national professional institution by manufacturing firm.Due to tonnage and the structural limitations of special fatigue test equipment, expansion joint diameter and axial length are all limited in 1000mm.Capacity of equipment is mainly limited to the blind plate thrust and the equipment size that overcome expansion joint.And because the power source of existing testing apparatus is all the top at expansion joint to be tested, the size of expansion joint to be tested being limited to, equipment size has also increased manufacturing cost after increasing.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned the deficiencies in the prior art, provides a kind of type metal expansion joint simple and practical, easy to operate, that cost is low multi-functional dynamic type approval test machine.
The technical solution adopted in the utility model is as follows:
The multi-functional dynamic type approval test machine of a kind of type metal expansion joint, it is characterized in that it includes the propulsion system of vertical setting, the upper end of described propulsion system is provided with bottom moving beam, the top of bottom moving beam is provided with top moving beam, between bottom moving beam and top moving beam, be provided with pressure transducer, the top of described top moving beam is provided with platform, on platform, be placed with swollen line pipe test block, on swollen line pipe test block sidewall, mobile fagging is installed, on the moving beam of described top, mobile pull bar is installed, the upper end of mobile pull bar is connected with described mobile fagging.
The bottom of described propulsion system is arranged on base, and described platform is also arranged on described base by many root posts.
The displacement transducer of its output shaft upper and lower displacement amount of test is installed on described propulsion system.
Described propulsion system are hydraulic cylinder.
Described mobile pull bar passes from platform.
Moving beam side, described bottom is arranged on column by slide guide device.
The beneficial effects of the utility model have:
The utility model structure is Open architecture, can not limit to some extent the size of expansion joint, simple and compact for structure and extendability is strong, can also realize external pressure torture test by frock, and cornering fatigue test etc., more can realize the type approval test that exceeds platform size.This equipment both can carry out rigidity test in the time of torture test, also can carry out the rigidity test of single-piece corrugated tube, and function is many.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, it includes the propulsion system 1 of vertical setting the utility model, and propulsion system 1 can be hydraulic cylinder, or electric cylinder etc.The bottom of propulsion system 1 can be arranged on base 9, also can be directly installed on ground.The upper end of described propulsion system 1 is provided with bottom moving beam 2, and the top of bottom moving beam 2 is provided with top moving beam 4, between bottom moving beam 2 and top moving beam 4, is provided with pressure transducer 3.The top of top moving beam 4 is provided with platform 5, is placed with corrugated tube test block 6 on platform 5, and mobile fagging 7 is installed on corrugated tube test block 6 sidewalls.Mobile pull bar 8 is installed on described top moving beam 4, and mobile pull bar 8 passes from platform 5, and the upper end of mobile pull bar 8 is connected with mobile fagging 7.Platform 5 can be arranged on base 9 by many root posts 10, and moving beam 4 two ends in top are slidably mounted on column 10.The utility model can be provided with the displacement transducer 11 of its output shaft upper and lower displacement amount of test on propulsion system 1.
Elemental motion of the present utility model is that propulsion system 1 drive bottom moving beam 2 and top moving beam 4, top moving beam 4 drives mobile pull bar 8 to move, mobile pull bar 8 drives mobile fagging 7, mobile fagging 7 drives corrugated tube test block 6 to pump, thereby reaches the object that swollen line pipe test block 6 is carried out to torture test.
When expansion joint product+core cylinder+mobile fagging is welded as after an airtight entirety, be arranged on this equipment, can realize withstand voltage test (hydraulic pressure) and tightness test (inflation), these two tests are to carry out under the state not moving at mobile fagging.When mobile fagging moves, it is torture test.Stiffness test has been mainly the measurement of corrugated tube rigidity power f under different displacements.Displacement is to gather by displacement transducer, and power is to gather by pressure transducer.When stiffness measurement, as long as completing a period of motion, moving beam just can measure rigidity value (measurement that rigidity can two products, also can single products independent measurement).
Other undeclared part that the utility model relates to is same as the prior art.
