Security incident and quality accident occur for destruction.
Sample relatively conventional at present, which prepares method, intermediate plate chucking method, sleeve pipe pressing, alloy casting method, direct chucking method
Etc. several.Intermediate plate chucking method is fixed at sample two ends with intermediate plate in supporting taper frock, and frock then is clamped in into examination
The machine bit of testing is tested；Suitable metal sleeve is loaded onto in sample two ends by sleeve pipe pressing, suppresses firm with forcing press,
Then tested on testing machine；Alloy casting method is to break up steel wire rope sample two ends steel wire, is cleaned up, then with molten
Melt alloy casting（Mostly using slicker solder or lead-tin-copper alloy as casting material is poured, the low melting points such as a small amount of tin bismuth antimony gold is added if necessary
Belong to reducing cast temperature）, it is cooled to after normal temperature on tensile testing machine and carries out tension test；Direct chucking method is by sample two
Direct clamping is held to be tested in the suitable jaw of pull test machine grip holder；What these test methods had can also determine steel strand wires
Actual times of fatigue, still, these methods more or less still suffer from following deficiency：1. during using intermediate plate chucking method, due to steel
The multilayer of twisted wire prevents sample from uniform stressed, and intermediate plate easily causes to damage and fracture of wire occurs to steel strand wires force part, tests
It can not be normally carried out.Sample landing is also easily caused simultaneously, and success of the test rate is not more than 30%；2. sleeve pipe pressing is needed for not
Same specification sample process metal sleeve, the thick gauge coupons in, institute's imposed load is up to more than 150kN during experiment, to up to
To preferable effect, then 1000 tons even 5000 tons of large pressing machine is needed, invest huge, cost is very high；3. alloy casting
Pernicious gas is produced in high energy consumption, cycle length, sample making course to people and environmental danger；4. direct chucking method is only applicable to directly
Small, the simple in construction steel strand wires in footpath, while also easily causing sample damage or sliding, success rate is extremely low, it is difficult to which Accurate Determining steel is twisted
The actual times of fatigue of line.
Utility model content

Spacing is used to fill charges
Charges described in the utility model are cotton or cloth floccule.
The inwall described in the utility model for pouring chamber is provided with width 0.2mm, depth 0.1mm, spacing 3-5mm screw thread.
The utility model has the advantages that:
In terms of the construction of device --- with simple in construction, the advantages of easy to operate, easy to spread；Test method side
Face --- have the advantages that the cycle is short, quick, dependable performance；In terms of cost --- have the advantages that material easily takes, reduces cost；
Environmentally friendly aspect --- have the advantages that environmental hazard is small, waste is easily handled；In terms of security performance --- with the safe thing of reduction
Therefore and the advantages of quality accident.The utility model is the manufacturer such as steel strand wires, user and testing agency provide manufacture, using and
The foundation of detection, it is to avoid because security incident and the quality accident of the disrumpent feelings generation of steel strand wires times of fatigue in use.

Fig. 1 is structural representation of the present utility model.
In figure：1st, charges, 2, umbrella termination, 3, steel bushing, 4, pour thing, 5, pour chamber, 6, sample.
Embodiment
With reference to accompanying drawing, embodiment of the present utility model is provided as follows.But the utility model does not limit to following examples.
As shown in Figure 1：It is identical including two set constructors that steel strand wires axial stress fatigue test described in the present embodiment determines device
And symmetrically arranged steel bushing 3.Described steel bushing 3 is drum, and the circle that the center of every group of steel bushing 3 has insertion is poured
Chamber 5 is built, the described chamber 5 that pours is structure as a whole with steel bushing 3, its wall thickness is 5-7mm, is opened in the inwall for pouring chamber 5
There is width 0.2mm, depth 0.1mm, spacing 3-5mm screw thread plays effectively increase and pours thing and the inwall frictional force of steel bushing 3
Effect, it is ensured that steel bushing 3 is not fallen off during experiment.There is 0.5- in exterior side port of the exterior side port away from steel bushing 3 for pouring chamber 5
1cm spacing, for filling charges, enables charges 1 and the secure seal of steel bushing 3.
In use, the two ends of steel strand wires sample 6 are made into umbrella termination 2, side termination can be first first positioned over one group of steel
In sleeve 3, appropriate charges 1 are placed pouring the termination of chamber 5, it is ensured that charges 1 can secure seal with steel bushing 3.Then will
Steel bushing 3 is positioned on support frame to ensure its upper end open upward, by stirring, the quick-hardening cement or epoxy of good fluidity
Resin cast thing 4 is poured into rapidly in casting die trial steel bushing 3, and drainage can be constantly stirred during pouring into, is full of until pouring casting material
Casting chamber 5.After quick-hardening cement or epoxy resin pour the solidification of casting material 4, you can other side termination is entered using same procedure
Row casting.After both sides quick-hardening cement or epoxy resin pour the solidification completely of casting material 4, the steel bushing 3 of the two ends of sample 6 is held on
Fatigue tester bit, by experimental condition imposed load, to determine the maximum times of fatigue of sample destruction.
The test method of steel strand wires fatigue test sample comprises the following steps：
1st, umbrella termination 2 is made in the two ends of steel strand wires sample 6.Concrete mode is：At the two ends of steel strand wires sample 6 away from one
Firmly tied up with materials such as soft iron silks respectively at clamping length L, the reverse twist direction direction in termination is broken up, umbrella termination 2 is made.And
Alignment must not be carried out to exposed steel wire in any case, but allow to bend to hook.
2nd, first the side umbrella termination 2 of steel strand wires sample 6 is positioned in one group of steel bushing 3.And in the port of steel bushing 3
Position, that is, pouring chamber 5, dorsad sample one end fills the thick charges 1 of 0.5-1cm, and the charges 1 can be the wadding such as cotton, cloth
Shape thing, it is therefore an objective to prevent that pour casting material in sample casting and forming process spills from steel bushing.Steel bushing 3 is two groups, construction
It is identical, the two ends of steel strand wires sample 6 are fixed respectively.
3rd, steel bushing 3 is positioned on support frame to ensure the upper end open of steel bushing 3 upward.By the casting after the completion of stirring
Thing 4 is quickly poured into pouring in chamber 5 in steel bushing 3, palpus constantly drainage during pouring into, it is to avoid bring bubble into, until casting
Thing, which is full of, pours chamber 5.
4th, after quick-hardening cement or epoxy resin pour the solidification of casting material 4, using same procedure to the other side of steel strand wires sample 6
Cast termination.
5th, after both sides quick-hardening cement or epoxy resin pour the solidification completely of casting material 4, the steel bushing 3 of the two ends of sample 6 is pressed from both sides
Fatigue tester bit is held in, by experimental condition imposed load, to determine the maximum times of fatigue of sample destruction.
The utility model does not specify part, is known technology.
