Larger power is born at straight position in the middle part of body, is gradually reduced from midship to hull both sides angle of outlet stress, and this stress is special
On the one hand the pulling force that upper supporting beam 5 is born can be reduced by putting, the stability of supporting beam 5, extends its service life in maintenance；It is more important
, make the loading characteristic of the suspension clamp 16 when experiment closer to its actual condition, test result naturally also just more subject to
Really.
10 one end of the connecting shaft is guide post 11, and the other end was terminal 12, and the guide post 11 will across the connecting hole 8
The lower supporting beam 6 is connected as one with the upper supporting beam 5, and 12 middle part of terminal of crossing is provided with conical through-hole 13, described
Steel strand wires 2 pass through the conical through-hole 13 and are fixed on the collet 4.
Such as Fig. 3, connecting shaft 10 divides for guide post 11 and crosses 12 two parts of terminal, and two parts role is also different.
Guide post 11 is for convenience to be connected as one upper supporting beam 5 and lower supporting beam 6；It crosses 12 middle part of terminal and is equipped with conical through-hole 13,
It is so that adjustable support 3 and fixing bracket 1 is connected in order to allow steel strand wires 2 that terminal 12 and fixing bracket 1 was passed through to link together
To constitute entirety.
Optionally, the middle part of the fixing bracket 1 is provided with location hole 14.
Such as Fig. 2, fixing bracket 1 can easily, be easily fixed on vertical puller system by location hole 14, complete to fix
Positioning of the holder 1 on vertical puller system.In conjunction with Fig. 4, when experiment, the fixing bracket 1 of experimental rig is fixed by location hole 14
In the fixing end of vertical puller system；Suspension clamp 16 is assemblied on adjustable support 3, and is fixed by the hole on 16 top of suspension clamp
In the mobile terminal of vertical puller system, after completing assembly, can load test power, carry out suspension clamp failure load test.
Wherein, the hull of suspension clamp 16 is attached to the 5 middle part outside of upper supporting beam of adjustable support 3, and hull bottom is straight
It is close to arc geosynclinal convex platform 7 in part.Steel strand wires 2 pass through suspension clamp 16, are located at the steel at neutral straight position in 16 hull of suspension clamp
2 part of twisted wire, while being also embedded in the arc slot of arc geosynclinal convex platform 7.This structure design, during load test power, pendency
Wire clamp 16 and upper supporting beam 5 can be bonded increasingly closer, naturally, the arc of steel strand wires 2 on its interior and arc geosynclinal convex platform 7
Groove face also the more can paste the more tight, and steel strand wires 2 can be fixed by the arc groove face of 16 hull bottom medial surface of suspension clamp and arc geosynclinal convex platform 7
Position, do not make steel strand wires 2 generate sliding or torsion, it can be ensured that the stability for testing process improves the precision of test result.
Optionally, the collet 4 is adjustable clamp.
Steel strand wires 2 are flexible frock, naturally occurring elasticity difference when assembly.If assembly is excessively loose, when load test power
May have the phenomenon that force unbalance, suffered resultant force may deviating device center line, cause test result wrong
Difference；If the tension of assembly, when the test force of load is also not up to the specified breaking load of suspension clamp 16, it is possible to steel occur
The situation that twisted wire 2 is broken, causes test failure, spends human and material resources, influence efficiency.Set collet 4 to adjustable clamp, so that it may
According to the different demands of different size suspension clamp 16, it is suitable that the elasticity of steel strand wires 2 is adjusted, and ensures stress balance, pushes
Experiment is steady to be carried out, and test force requirement is reached, it is ensured that test result is effectively, accurately.
Optionally, the guide post 11 is screw rod, and the upper supporting beam 5 can move on the guide post 11.
Optionally, it is arranged with nut 15 on 11 outer wall of the guide post.
The suspension clamp 16 of different size model has the different angles of outlet, (its leading of being adapted to of overhanging corner as defined in standard
Folded acute angle between line and the tangential direction and horizontal line of circular arc at suspension clamp outermost contact point) range is also different.
Such as Fig. 4, position of the upper supporting beam 5 on guide post 11 is different, then upper supporting beam 5 arrived the cone that 12 middle part of terminal is arranged
The distance of shape through-hole 13 is just different, the also not phase of the angle across the steel strand wires of conical through-hole 13 and 16 horizontal line of suspension clamp
Together.Upper supporting beam 5 can move on guide post 11, so that it may meet requirement of the different size suspension clamp 16 to overhanging corner, make this reality
It applies the experimental rig described in example not knowing to be suitable for specific suspension clamp 16, but the suspension clamp of all specifications is applicable in.
Upper supporting beam 5 can move on guide post 11, then during test force loads, upper supporting beam 5 will necessarily take off
Guide post 11 is separated out, causes experiment that can not carry out.Therefore, guide post 11 is screw rod in this experimental rig, then mating setting nut 15, i.e.,
Upper supporting beam 5 can be fixed on guide post 11.It is worth noting that, nut 15 was arranged far from the upper supporting beam 5 of terminal 12
Side.Stress of this experimental rig on vertical puller system determines that nut 15 is arranged in above-mentioned position, can stop
Supporting beam 5 is sliding out the trend of guide post 11, without worrying that upper supporting beam 5 has the tendency that reverse movement.Also, in practical operation
In, to specific suspension clamp 16, it can first determine position of the nut 15 on guide post 11, then also determine that upper supporting beam 5
To the distance of conical through-hole 13, overhanging corner can be controlled in standard prescribed limit.
Experimental rig described in the present embodiment only defines that guide post 11 is screw rod and is matched with nut 15, and to connecting hole
8 do not limit.Naturally, the diameter of connecting hole 8 must match with the diameter of guide post 11, otherwise upper supporting beam 5 and lower support
Small relative motion may be will produce between beam 6, influence test result.Connecting hole 8 can be the hole of inner wall smooth, can also
It is female hole；If there is internal thread, in loading process, frictional force can be further increased, makes supporting beam 5 and guide post
11 connection is more secured；If inner wall smooth, coordinate by guide post 11 and nut 15, can also fix the position of supporting beam 5, to experiment
As a result accuracy is without larger impact.
Optionally, the diameter of the guide post 11 is less than the diameter for crossing terminal 12.
Such as Fig. 3, the diameter of guide post 11 was less than the diameter of terminal 12, then can be limited to the moving range of upper supporting beam 5
On guide post 11；Otherwise, if upper supporting beam 5 can move on crossing terminal 12, may to positioned at conical through-hole on terminal 12
13 impact, and so that conical through-hole 13 is worn, reduce the service life of experimental rig.
Optionally, 12 outside of terminal is crossed in the large aperture end of the conical through-hole 13 positioned at described, the conical through-hole 13
Small-bore end is located at described cross on the inside of terminal 12.
As can be seen that the large aperture end of conical through-hole 13 from the semi-cutaway (right side) of 3 structural schematic diagram of adjustable support in Fig. 3
It was located at 12 outside (being exposed to the side outside whole device) of terminal, the small-bore end of conical through-hole 13 was located in terminal 12
Side (side opposite with outside).
Such as Fig. 4, the structure of suspension clamp 16 and its loading characteristic in practical application determine that steel strand wires 2 are centrosymmetric
Bending, then only by cross terminal 12 on hole be set as inclined hole identical with 2 inclined degree of steel strand wires, just can guarantee steel strand
Line 2 still keeps smooth, straight in through hole.If cross the hole on terminal 12 be horizontal through hole or with 2 inclined degree of steel strand wires not
Same inclined hole, steel strand wires 2 certainly will turn back at the both ends in hole, and with the load of test force, the degree of turning back can be increasingly severe, so that it may
Steel strand wires 2 can be caused to fracture in through hole, lead to test failure.
If only setting hole to inclined hole identical with 2 inclined degree of steel strand wires, as shown in figure 4, being clipped broken carrying out catenary
When bad load test, suspension clamp 16 and adjustable support 3 are an entirety always, synchronizing moving are kept, so inclined hole can be protected
Overhanging corner is demonstrate,proved in standard prescribed limit.But with the increase of test force, the separation degree of fixing bracket 1 and adjustable support 3
Also bigger, in inclined hole close to one end of fixing bracket 1, steel strand wires 2 will be bent to the direction of 1 stress of fixing bracket, test force
A certain size is arrived, steel strand wires 2 may be pulled off at inclined hole；Even if the maximum test force applied will not disposably break steel
Twisted wire 2, through test of many times, steel strand wires 2 also can constantly be worn at inclined hole, or even fracture, and this reduces making for steel strand wires 2
With the service life, in the continuous friction process of steel strand wires 2 and inclined hole, inclined hole also can gradually be worn.
Therefore, the embodiment of the present application by positioned at inclined hole on terminal 12 be set as conical through-hole 13, cross 12 inside of terminal
For the small-bore end of conical through-hole 13, it ensure that overhanging corner in standard prescribed limit；It is conical through-hole 13 to cross 12 outside of terminal
Large aperture end, expand close to 1 both ends of fixing bracket steel strand wires 2 scope of activities, can effectively mitigate experiment during steel
The abrasion that twisted wire 2 can occur delays the service life of steel strand wires 2, also improves the stability of experimental rig.
Optionally, in the arc geosynclinal convex platform 7, the diameter of arc slot is more than the diameter of the steel strand wires 2.
The effect of arc slot is to be embedded in steel strand wires 2 wherein, then the diameter of arc slot must be more than the diameter of steel strand wires 2.
If not, arc slot is identical with 2 diameter of steel strand wires, and steel strand wires 2 will necessarily occur a degree of during embedded arc slot
Crimp, this deform always exists during entire experiment, if things go on like this, will necessarily influence the use of steel strand wires 2；If
The diameter of arc slot is less than the diameter of steel strand wires 2, then steel strand wires 2 can be stuck in arc slot both sides, with the load of test force, steel strand wires 2
It can be squeezed into arc slot always, then being in the steel strand wires 2 of arc slot both sides will certainly be worn, not only detract making for steel strand wires 2
With the service life, and when test force is not up to the specified breaking load of suspension clamp 16, steel strand wires 2 are possible to send out in fray
Raw fracture, influences being smoothed out for experiment.
Optionally, the material of the fixing bracket 1 and the adjustable support 3 is No. 45 steel or high duty alloy mould steel.
No. 45 steel are carbon constructional quality steel, and hardness is not high, is easy to machining, are had after conditioned processing good comprehensive
Close mechanical performance；High duty alloy mould steel has higher hardness and strength, good wearability and enough toughness.With
This two classes steel makes the fixing bracket 1 and adjustable support 3, disclosure satisfy that 3 palpuses of the fixing bracket 1 and adjustable support
Performance requirement, so that the stability of experimental rig is obtained basic assurance.
Experimental rig provided by the present application, can be according to the difference and adaptation of 16 angle of outlet of suspension clamp of different model specification
