Description
Technical field
The present invention relates to a kind of fixture, especially a kind of clamp of steel wire rope tension test machine.
Background technology
According to GB/T8358-2006 " breaking tensile test of rope method ", there are four kinds to the method for chucking of wire rope test specimen: cover platen press, casting method, directly chucking method and winding method.The above method all adopts sampling Detection method, both on existing whole-root rope basis, intercepts one section, and carries out breaking tensile test.This test is that process of the test prevents test specimen from clamping the loosening slippage of position appearance for the requirement of two ends clamp body, and whether sustain damage for test specimen clamping position does not clearly propose and study.These class methods are applicable to detection and the examination of new rope, and for the wire rope used, the performance at middle part and fag end position will occur difference, will be no longer representative from fag end sampling, and in the middle of rope, sampling will bring damaging influence to rope.
Current domestic electrical construction uses a large amount of wire rope, such rope for left and right ordinary lay programming structure, stretch stressed after have and anti-ly turn round function, widespread use in lead wire and earth wire construction under tension stringing.Because such rope environment for use is severe, stressed complexity, onsite application process very easily causes yarn, rope silk wear and rupture.Be all that coiling is deposited after such rope returns to warehouse, how take a kind of rational method to launch wire rope and carry out monitored over time, online random tension test does not also have ready-made testing machine solution both at home and abroad.
According to power construction safety work order, Electric Power Construction Enterprises needs stringing every year with preventing that turning round wire rope carries out 2 times of safe load tensile tests, whether can continue safe handling to detect such rope, qualified rear wire rope still needs to come into operation after testing.Such test is safety examination, does not belong to destructive test.One of method that current constituent parts adopts uses for reference wire rope disrumpent feelings property tensile test method, the test of the sampling section of getting.Mostly is in actual applications near fag end sampling, has occurred sampling confinement problems.These class methods destroy the integrality of whole rope simultaneously, and the process of fag end shank does not with great difficulty bring hidden danger, and the object checked with property safety period deviates from mutually.Some units also adopt steel wire clamp to clamp one section of wire rope to carry out tension test, and this kind of method achieves online test objective, but for the wire rope of cheese inside, owing to cannot effectively launch, cause detection to realize.Steel wire clamp Lack of support simultaneously, fully do not hold tactile to wire rope surface, process of the test easily causes secondary extrusion to steel wire.
In sum, at present the domestic tensile test about wire rope be mainly reflected in intercept termination carry out in off-line tensile test, for the wire rope sample of different length, testing machine is taked arrange the mode that hitch point fixed by many places different length wire rope; And for the tensile test method of wire rope, its patent and document achievement also many adopt separately casting method, winding method, gland method and directly clamp method carry out.For total length force type wire rope intercept termination carry out off-line tensile test can not the authentic security situation of objective evaluation wire rope, four kinds of fixture test methods that industry standard is recommended also are the off-line testing being suitable for sampling, and the safety testing larger for pulling force often produces damage to bare terminal end.Therefore a kind of harmless online tensile test fixture being suitable for wire rope of development research, has important engineering significance and theory value.
At present, the solution not yet had.
Summary of the invention
Technical assignment of the present invention provides a kind of clamp of steel wire rope tension test machine for above-mentioned deficiency of the prior art, this clamp of steel wire rope tension test machine, by winding method and direct chucking method organic integration, effectively achieves the clamping of the not damaged tensile test sample compared with large-tonnage wire rope; Can this clamp structure can realize the online tensile test of not disrumpent feelings grab sample of wire rope, provide effective guarantee safely to the whole spooling of inspection; Stationary fixture devises both sides fluting, exchanges, can significantly improve the feature in fixture life-span after wearing and tearing.
The technical solution adopted for the present invention to solve the technical problems is: it comprises S clamp, and described S clamp comprises stationary fixture and dynamic fixture, and described stationary fixture cross section is V-shaped, and slot in both sides, described stationary fixture is fixed on base plate; Described dynamic fixture cross section entirety is convex, pressing surface becomes dimple form, pipe S shape bending clamp compact space is formed after described dynamic fixture and stationary fixture combine, described dynamic fixture is connected with dynamic clamping fixture seat, described dynamic clamping fixture seat is connected with horizontal sliding oil cylinder, and described horizontal sliding oil cylinder is arranged on base plate.
Described stationary fixture is fixed on base plate by the thick axle of pier and alignment pin, and the thick axle of described pier comprises 3, is evenly arranged in the hole of stationary fixture respectively, is fixed between the thick axle of described pier and base plate by alignment pin.
Described dynamic fixture is connected with dynamic clamping fixture seat by bolt.
Described horizontal sliding oil cylinder comprises two, is connected respectively with dynamic clamping fixture seat.
Clamp of steel wire rope tension test machine of the present invention compared to the prior art, there is following outstanding beneficial effect: fully absorb the tight new application of existing wound form clamping peace pushing: S shape bends, effectively increase and tactile area and length are held to wire rope, under identical friction material and snap-in force situation, improve the stiction to wire rope; Wire rope is through repeatedly bending coiling in the space of dynamic fixture and stationary fixture composition, and produce friction pulley skin-friction effect, friction force progressively decays, and dynamic fixture horizontal sliding snap-in force is corresponding can reduce, and effectively can reduce and damage the compression of wire rope; Can this clamp structure can realize the online tensile test of not disrumpent feelings grab sample of wire rope, use providing effective guarantee to the whole spooling of inspection safely; Stationary fixture devises both sides fluting, exchanges, can significantly improve the fixture life-span after wearing and tearing.
