Description
Technical field
The utility model relates to a kind of tube bending deformation test loading system.
Background technology
In gas delivering pipe flexural deformation test, developmental tube belong to high grade of steel mostly and diameter/wall ratio bigger, press and bend loading in bearing simultaneously during test, load is all bigger.Pressure and the crooked compound loading mode that loads have certain degree of difficulty in the developmental tube; But resistance capacity to deformation and the strain hardening ability of gas delivering pipe under bending load is the important evidence of pipeline design; Simultaneously also be the reliable basis of pipeline safety operation, so the performance test of gas delivering pipe under the actual military service load of simulation more and more obtains people's attention.The direction and the emphasis that precisely, stablize, reliable crooked charger become research.
There is Britain institute of welding TWI in the mechanism that has at present similar test capability in the world, research institutions such as Canadian C-FER company.Wherein the homogeneous tube bending test system of TWI has adopted the equipment structure of four-point bending, through two strong points steel pipe is applied moment of flexure; Canadian C-FER then is on the basis of a large-scale vertical drawing machine, installs the arm of force additional steel pipe is applied moment of flexure (Fig. 1 b).It is big that the former has load, the advantage that test capability is strong, but the test form of four-point bending causes the local deformation of steel pipe easily.Though the latter's the problem that does not have local deformation, because testing equipment receives the space constraint of large-scale drawing machine, developmental tube is too short, is difficult to apply enough moments of flexure, and often will attaches very strong axial compression load.They can not obtain desirable flexural deformation test condition.
The utility model content
The purpose of the utility model provides a kind of tube bending deformation test loading system, through adopting horizontal device structure, solves the problem of equipment test ability.Use two arm of forces to load, and arm of force long enough, sufficient bending load can be obtained.Easy to operate, safe and reliable developmental tube machinery loading device, and be applicable to the high pressure of different-diameter, wall thickness, high grade of steel gas delivering pipe.
The described tube bending deformation test of the utility model loading system is to be made up of cylinder apparatus, sphere coupling arrangement, coupling shaft, self-oiling bearing, plain bearing housing, preceding shoring of foundation, the fixation side arm of force, developmental tube, transition rings, joint flange, mobile side force arm, coupling shaft, bearing, fixed bearing block, back shoring of foundation, adjustment joint, middle shoring of foundation, bearing beam;
The fixation side arm of force links through coupling shaft, bearing and fixed bearing block; The bearing beam of fixed bearing block and four H shaped steel links; Bearing beam is by back shoring of foundation, middle shoring of foundation horizontal fixed; Bearing beam is provided with the adjustment joint;
