Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and examples.
The band load flex Expansion Test apparatus of solid expansion pipe provided by embodiment is by Load test framework and bend test
Platform is constituted.
As shown in Figure 1, Load test framework uses horizontal type structure, by hydraulic cylinder 1, mainframe 6 and housing cradle 7 are formed, host
Frame 6 is in rectangular design using steel welding structure, and intermediate position is not blocked, and space is larger, can be put into bend test platform, rack material
Material can satisfy the maximum load of 2000KN by annealing.What is be connected on the right side of mainframe 6 with hydraulic cylinder 1 is piston rod
3, piston rod 3 connects with pulling force clamp 5, for joint test expansion tube and applies axial load, clamp fixed frame 4 and host
Frame 6, which is connected, to be used to support pulling force clamp 5.Design has reaction force frame 11 on the left of mainframe 6, passes through anchor tip 9 and experiment
It is connected with expansion tube, reaction force frame 11 is axially movable, and passes through the upper portion side wall both sides of upper and lower two bolts 10 and mainframe 6
A series of pin holes 8 of equidistant placement fix position, to adapt to different length expansion tube experiment demand.Design above Load test framework
There is protective cover, can push and pull in left-right direction, can both prevent that wound caused by fluid power and mechanical force when accident occurs during test
Evil, and the handling of sample are not influenced.
As Figure 2-3, bend test main platform body is steel construction carrier 17, is in 17 upper surface of steel construction carrier
Plane and the 5 V-shaped roller bearings 15 that are equally spaced, each V-shaped roller bearing 15 is connected with the small-scale liquid cylinder pressure 16 of lower section may be implemented
Lower movement and positioning may be implemented axially to build in bend test platform by adjusting the different lifting heights of 5 V-shaped roller bearings 15
Found certain crooked radian.There is floating sleeve 13 in the right end design of bend test platform, design has 2 above floating sleeve 13
A lift angle pressing plate 14 is equipped with support cylinder 12 for adjusting the angle of floating sleeve below floating sleeve 13, for adjusting
The height of floating sleeve 13；In the left side of bend test platform, design has a fixation clip 21, flat by lead screw 20 and bending
Platform connection, is similarly designed with a support cylinder 19, the height of adjustable platform in lower section；In entire bend test platform lower
There are two groups of connecting brackets 18, being fixed when for being put into Load test framework with mainframe.
As shown in figure 4, carry out simulation operating condition carry out bending expansion test when, first adjust bend test platform on it is several
V-shaped roller bearing 15 rises to the height calculated, to realize certain bending curvature.Then test is tried with expansion tube 24 from bending
It is penetrated in the floating sleeve 13 tested on platform, at the fixation clip 21 that left side is reached after the V-shaped roller bearing 15 being successively adjusted,
Adjusting screw 20 is fixed pressing plate 21, since fixation clip 21 and floating sleeve 13 are applied with developmental tube both ends height direction
Downward constraint, so that the tightly table on the 5 V-shaped roller bearings 15 and steel construction carrier 17 for having certain curvature of developmental tube 24
Face realizes the foundation of the predefined curved degree of developmental tube, while not constraining in developmental tube axial direction, can reload axial load
Lotus simultaneously allows developmental tube axially having length variation.
Expansion cone loading is tested in expansion tube and in expansion tube both ends welding plug, when progress is without axial load when test
When expansion test, hydraulic water is directly injected by high pressure water injection pipe 25 in the plug one end for having expansion cone and pushes expansion cone completion swollen
Swollen test process；When needing 24 both ends of expansion tube sample to apply axial load, the bend test of expansion tube sample 24 will be installed
Platform is put into Load test framework, and the welding plug at 24 both ends of expansion tube sample is connected with pulling force clamp 5 and anchor tip 9 respectively,
Entire bend test platform is fixed by the two groups of connecting brackets 18 and mainframe of lower part, is opened hydraulic cylinder 1, is passed through piston rod 3
Pulling force clamp 5 is driven to apply axial load to expansion tube one end, it is logical in the plug one end for having expansion cone when load applies in place
Excessively high pressure injection water pipe 25 injects hydraulic water and expansion cone is pushed to complete expansion test process.
In experiment, force snesor is housed on pulling force clamp, hydrostatic sensor is housed on high pressure water injection pipe, hydraulic swollen
It can measure magnitude of load and hydraulic coupling during swollen.Meanwhile in the top of mainframe, design has laser displacement sensor, passes through photograph
Emitter following the mobile position instruction frame of expansion cone be used to record the speed and displacement in expansion tube expansion process.
Apparatus of the present invention apparatus structure is simple, safe and reliable, can be to different size, different grade of steels, different expansion rates
Expansion tube simulates operating condition and carries out the bending expansion test with load, is with a wide range of applications.
