, due to the characteristic of pipe material of ductile iron pipe itself, from manufacturing and designing, upward all corresponding code requirement has been proposed in construction and installation.Such as GB/T 13295-2008 " water and gas pipeline ductile iron pipe, pipe fitting and annex " GB/T 17457-2009 " ductile iron pipe and pipe fitting sand-cement slurry liner " ISO 16132-2004 " encapsulated layer of ductile iron pipe and accessory cement plaster lining ".
, to the improving constantly of ductile iron pipe performance requirement the device research and development of its performance test are brought into schedule along with people, as " cast tube with the development of type approval test machine ".At present, a lot of to the desired experimental check of ductile iron pipe, most of experimental provision separates separately, and namely test one device, so not only reduced plant factor but also taken a large amount of places.Simultaneously also can't adapt to new testing requirements, as hydraulic circulation test as described in document " performance study of ductile iron pipe sand-cement slurry liner water-base epoxy surface plot layer " etc.
The utility model content
The technical problems to be solved in the utility model is to provide the combined test apparatus of a kind of body sealing joint and hydraulic circulation, this device can carry out sealing joint detection and hydraulic circulation test experiment to ductile iron pipe simultaneously, avoided the defect of experiment one device, improve the utilization factor of equipment, facilitated personnel's operation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the comprehensive experimental device of a kind of body sealing joint and hydraulic circulation, it is characterized in that comprising square base, the two ends of described base are installed with front barricade and rear barricade, connected by pull bar between described front barricade and rear barricade, be provided with the pushing tow hydraulic cylinder at the middle part of front barricade, it is stifled that the telescopic end of pushing tow hydraulic cylinder is equipped with movable end, be provided with screw-down and deflection hydraulic cylinder in the middle part of base, described screw-down and deflection hydraulic cylinder are placed between front barricade and rear barricade.
Said structure is described further, connects by four pull bars between described front barricade and rear barricade, four railings are distributed in four angles of barricade.Four pull bars and front and back barricade in the utility model are fixed, and are distributed in four angles, in experimentation, when the pushing tow hydraulic cylinder is exerted pressure, guarantee that pressure can act on ductile iron pipe uniformly, before and after making, barricade can not be out of shape, and it is stressed to improve base, improves the reliability of pick-up unit.
Said structure is described further, and described screw-down comprises two door-shaped frames that are fixed in the base both sides, and the horizontal cross-arm on described framework is provided with depression bar moving up and down.Screw-down in the utility model is fixedly connected with base, can apply downforce to cast carbon steel, has therefore designed the framework of door shape, under the prerequisite that does not affect inner cast carbon steel detection, can slowly evenly apply downward pressure.
Said structure is described further, and described deflection hydraulic cylinder is two, is relatively arranged on the both sides of base, and two deflection hydraulic cylinders are placed perpendicular to the body axis horizontal.The deflection hydraulic cylinder is fixedly connected with base, can make cast tube to be measured in the surface level swing, by the deflection oil cylinder of both sides, is exerted pressure in the coupling part of cast carbon steel, offsets the lateral deviation power that produces in experimentation, avoids damaging cast carbon steel.
The beneficial effect that adopts technique scheme to produce is: the utility model adopts pushing tow hydraulic cylinder and deflection hydraulic cylinder to improve automaticity and the controllability of equipment, lengthen the length of former test unit, integrated screw-down to increase the adaptability of equipment, adopt Tiebar structure to improve base stressed.The utility model can be applicable to sealing joint and the hydraulic circulation compbined test has improved plant factor, adopt Tiebar structure improve system stressed, improved reliability.
