Embodiment Construction

[0015] figure 1 , 2 A block diagram of a complex load testing machine is shown. In the figure, the complex load testing machine includes a main engine 1 and a combined hydraulic source 6 arranged in a pit 8, an electronic control computer 2, a sample transport trolley 3, an internal pressure loading device 7 and a measurement control system. The main engine adopts a frame structure formed by connecting four reaction frames 9 to the top fixed beam 12 and the base 29 respectively, an axial force loading device and a bending moment loading device.

[0016] The axial force loading device is set in the frame structure. The movable beam 13 is driven by a hydraulic motor 35 through four lead screws 10 and lifted up and down along the reaction force frame 9 by means of rollers 14. The lower part of the movable beam 13 is connected with a 6000KN sensor 16 and an upper ball joint in turn. 17 and upper curved beam 20. Mounting bases for four lead screws 10 and hydraulic motors 35 are ...

Abstract

The invention discloses a complex load tester, and belongs to the technical field of pipeline testing. A host machine of the tester comprises an axial force loading device, a bending moment loading device, an internal pressure loading device, a hydraulic system and a measurement control system. The complex load tester can individually apply an axial load, bending moment, internal pressure and the like to a steel tube test sample, also can apply two or more combined loads simultaneously, can simulate the real stress environment of an oil gas conveying steel tube, can apply a load statically, and also can supply a load in a low-frequency reciprocating mode. An electro-hydraulic servo enclosed loop measurement control system is adopted for the tester so as to control constant speed test force and constant speed displacement; the control modes can be switched stably in the testing process; data of load, internal pressure, displacement, deformation and the like can be collected automatically in the testing process, and the recording and the like of the test data can be completed automatically. The tester corresponds to the relevant national standards and industry standards in structure, function, performance and the like, and has the advantages of good integral performance, high control accuracy, good simulation effect, good reliability, simple operation and the like.

Description

technical field [0001] The invention relates to a complex load testing machine, which belongs to the technical field of pipeline testing. Background technique [0002] In order to study the bearing capacity and failure mechanism of oil and gas transmission pipelines under complex loads, and accurately evaluate the ultimate bearing capacity of pipelines, it is necessary to conduct full-scale simulation tests on steel pipes. In the running state, the pipeline is not only affected by internal pressure, but also by its own gravity and the support of the surrounding soil, the axial force caused by the temperature of the conveying medium, the axial force caused by geological subsidence, landslides, seismic fluctuation effects, and fault dislocation and bending moment, the impact load caused by heavy objects, the drag force and lift force generated by the submarine suspension pipeline under the action of waves and currents, etc. The force model of the pipeline under complex enviro...
