Description
Technical field
The utility model is related to a kind of fixture used when composite material electric pole is tested, especially a kind of composite wood
Expect electric pole mechanical property test fixture.
Background technology
In recent years, it is the safety of raising power network line, using the high composite material of high tenacity and specific strength in engineering
Electric pole.Composite material electric pole can reduce collapsing for line pole, can also improve the corrosion resistance of electric pole, can substantially reduce and apply
Work difficulty improves construction efficiency, so be widely used.
Currently, composite material electric pole category hollow thin-wall type structure, because Modulus of Composites is low, non-deformability is poor,
When electric pole cantilevered is tested, usually test fixture is sleeved on by the tested local location of electric pole, at this time electric pole part at chuck
The effect of being squeezed, the constraint of electric pole section is uneven, and circular cross-section will become elliptic cross-section under external force in electric pole section, electricity
Bar bending resistance weakens significantly.However actual tests are found, same composite material electric pole, using different experimental rigs, especially
It is the difference of test fixture structure construction to composite material that it is different fixtures has apparent difference, main cause to test result
The deformation restriction ability of stress maximum has differences, and different fixtures are to the actual loading characteristic in composite material electric pole buried depth
Simulation accurately differs, and composite material electric pole premature degradation is easily led to if insufficient to composite material electric pole deformation constraint, cannot
Accurately reflect the stress of composite material electric pole.Therefore existing testing stand fixture cannot be guaranteed that the full angle of electric pole circumferential direction becomes
Shape constrains, and cannot simulate the stress of electric pole very well, has limitation.
Invention content
The purpose of this utility model is that according to prior art shortcoming and provide that one kind can realize can be in circumferential direction
Full angle constrains the composite material electric pole mechanical property test fixture of electric pole circumferential deformation.
The purpose of this utility model is realized by following approach：
A kind of composite material electric pole mechanical property test fixture, structural feature be, includes left chuck and right chuck,
Two chucks are crescent-shaped conformation, and after split, centre is the circular hole clipping hole being adapted to electric pole, and left chuck and right chuck include
Affixed side and active side；The affixed side of two chucks is concave-convex alternate claw type construction, can be mutually butted with it is nested, and pass through
One axis pin is attached, at this point, two chucks are rotated using the axis pin junction as axis so that the active side of two chucks can live
Dynamic folding；The active side of two chucks is equally concave-convex alternate claw type construction, can be mutually butted with it is nested, and pass through one and sell
Bolt is attached and fixes.
As a result, in use, opening pin, the active side of two chucks of interlocking is then opened, electric pole is put into card hole, so
It is closed the active side of two chucks afterwards, be inserted into pin and is fixed.It is mutually butted the claw type alternate with nested bumps and constructs energy
Enough realize being stably connected with for joint.The utility model is proposed by fully considering composite material electric pole construction and mechanical characteristic
Openable and closable rabbet joint type fixture, can full angle constrain circumferential deformation, compare traditional fixture, the simulation to electric pole root stress
Property it is more acurrate, electric pole root circumferential direction stress can be constrained, closer to actual conditions.
The utility model can be specially further：
After the active side of left chuck and right chuck is opened, open angle is 0 degree~60 degree.
After the active sides of two chucks is opened, angle should can adapt to electric pole and be put to the test the disengaging size at place.
Further include that there are two hanging rings, is located at edge on the outside of the active side of left chuck and right chuck.
Hanging ring is used for auxiliary operation.
The axis pin is to be installed along the thickness direction of left chuck and right chuck, and the pin is then along left chuck and the right side
The length direction of chuck is installed, and axis pin and pin are spatially to be mutually perpendicular to.
The fixed form of this spatial vertical enables to fixture to have more stability.
The pin is a kind of bolt of long stem, and one end is nut fixing end, and the other end is then external screw thread, can connect spiral shell
It is female.
In this way, after the active side interlocking of two chucks of left and right, it is inserted into pin, is then screwed in nut, pin is consolidated
It is fixed, it realizes and two chuck active sides of left and right is fixedly connected, while nut can also be dismantled, unload pin, open left and right chuck.
In conclusion the utility model provides a kind of composite material electric pole mechanical property test fixture, buried according to electric pole
Depths electric pole circumferential direction stress and deformation characteristics, use it is retractable can full angle constraint circumferential deformation can rabbet joint type fixture, phase
It is more acurrate to the simulation of electric pole root stress than traditional fixture, electric pole root circumferential direction stress can be constrained, closer to practical feelings
Condition.
