Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and examples.
The solid expansion pipe band load flex Expansion Test apparatus that embodiment is provided are 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 constituted, main frame
Frame 6 uses the rectangular design of steel welding structure, and middle part is not blocked, and space is larger, can be put into bend test platform, frame material
Material can meet the maximum load of 2000KN by annealing.What is be connected with hydraulic cylinder 1 on the right side of mainframe 6 is piston rod
3, piston rod 3 connects with pulling force dop 5, for joint test expansion tube and applies axial load, dop fixed mount 4 and main frame
Frame 6 is connected and is used for supporting pulling force dop 5.Reaction force frame 11 is designed with the left side of mainframe 6, by anchor tip 9 and experiment
It is connected with expansion tube, reaction force frame 11 is axially movable, by upper and lower two latches 10 and the upper portion side wall both sides of mainframe 6
A series of pin-and-holes 8 of equidistant placement come fixed position, to adapt to different length expansion tube experiment demand.The design of Load test framework top
There is protective cover, can push-and-pull in left-right direction, the wound that fluid power and mechanical force are caused when can both prevent from occurring unexpected in process of the test
Evil, and the handling of sample are not influenceed.
As Figure 2-3, bend test main platform body is steel construction carrier 17, is in the upper surface of steel construction carrier 17
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 can be realized
Lower movement and positioning, by adjusting 5 different lifting heights of V-shaped roller bearing 15, it is possible to achieve axially built in bend test platform
Vertical certain crooked radian.Floating sleeve 13 is designed with the right-hand member of bend test platform, 2 are designed with the top of floating sleeve 13
Individual lift angle pressing plate 14, for adjusting the angle of floating sleeve, is provided with support cylinder 12, for adjusting below floating sleeve 13
The height of floating sleeve 13；A fixation clip 21 is designed with the left of bend test platform, by leading screw 20 and bent flat
Platform is connected, and a support cylinder 19, the height of adjustable platform are similarly designed with lower section；In whole bend test platform lower
There are two groups of connecting brackets 18, being fixed with mainframe during for being put into Load test framework.
As shown in figure 4, when simulation operating mode carries out bending expansion test, first adjusting several on bend test platform
V-shaped roller bearing 15 rises to the height for calculating, to realize certain bending curvature.Then experiment is tried with expansion tube 24 from bending
Penetrated in the floating sleeve 13 tested on platform, sequentially passed through at the fixation clip 21 on the left of reaching after the V-shaped roller bearing 15 adjusted,
Adjusting screw 20 is fixed pressing plate 21, because fixation clip 21 and floating sleeve 13 are applied with to developmental tube two ends height direction
Downward constraint so that developmental tube 24 is tightly close to the 5 V-shaped roller bearings 15 and the upper table of steel construction carrier 17 for having certain curvature
Face, realizes the foundation of the predefined curved degree of developmental tube, while not constrained in developmental tube axial direction, can reload axial load
Lotus and allow developmental tube axially having length change.
Expansion cone is loaded in experiment expansion tube and in expansion tube two ends welding plug during experiment, when carrying out without axial load
During expansion test, hydraulic pressure water is directly injected by high pressure water injection pipe 25 in the plug one end for having expansion cone and promotes expansion cone completion swollen
Swollen process of the test；When needing the two ends of expansion tube sample 24 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 the two ends of expansion tube sample 24 is connected with pulling force dop 5 and anchor tip 9 respectively,
Whole bend test platform is fixed by two groups of connecting brackets 18 and mainframe of bottom, hydraulic cylinder 1 is opened, by piston rod 3
Pulling force dop 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
The too high injection hydraulic pressure of pressure injection water pipe 25 water promotes expansion cone to complete expansion test process.
In experiment, force snesor is housed on pulling force dop, hydrostatic sensor is housed on high pressure water injection pipe, it is swollen in hydraulic pressure
Measurable magnitude of load and hydraulic coupling during swollen.Meanwhile, laser displacement sensor is designed with above mainframe, by shining
Penetrating the position instruction frame moved with expansion cone is used to record speed and the 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 steel, different expansion rates
Expansion tube simulation operating mode carries out the bending expansion test with load, is with a wide range of applications.
