Abstract
The invention discloses a clamp of a steel wire rope tension test machine and belongs to a clamp. The clamp structurally comprises an S-shaped clamp, wherein the S-shaped clamp comprises a fixed clamp and a moveable clamp; the section of the fixed clamp is V-shaped; the two sides of the fixed clamp are grooved; the fixed clamp is fixed on a bottom plate; the whole section of the moveable clamp is convex; a pressed surface is shallowly concave; the moveable clamp and the fixed clamp are combined to form a round tube S-shaped bending clamping space; the moveable clamp is connected with a moveable clamp seat; the moveable clamp seat is connected with a horizontal pushing oil cylinder; the horizontal pushing oil cylinder is arranged on the bottom plate. The clamp organically integrates a winding method and a direct clamping method to effectively realize clamping of a test sample of a non-damage tension test of a large-tonnage steel wire rope. The clamp structure can realize non-broken on-line random sampling tension test of the steel wire rope and provides an effective guarantee to inspect whether the whole steel wire rope is safe or not. The two sides of the fixed clamp are grooved, so the clamp has the characteristics that the grooves can be exchanged after being worn; and the life of the clamp can be prolonged exponentially.
Description
Technical field
The present invention relates to a kind of fixture, especially a kind of lineoutofservice signal pull grip of testing machine.
Background technology
According to GB/T8358-2006 " breaking tensile test of rope method ", the method for chucking of wire rope test specimen is had to four kinds: cover platen press, casting method, directly chucking method and winding method.The above method all adopts the sampling Detection method, both on existing whole-root rope basis, intercepts one section, carries out disrumpent feelings tension test.This test is that process of the test prevents whether loosening slippage from appearring in test specimen chucking position, sustain damage and clearly do not propose and study for test specimen chucking position for the requirement of two ends clamp body.These class methods are applicable to detection and the examination of new rope, and for the wire rope used, difference will appear in the performance at middle part and fag end position, from the fag end sampling, will be no longer representative, and in the middle of rope, sampling will bring damaging influence to rope.
Current domestic electric power construction is used a large amount of wire rope, and such rope is for left and right ordinary lay programming structure, stretches after stressed and has anti-turn round function, widespread use in the lead wire and earth wire construction under tension stringing.Because such rope environment for use is severe, stressed complexity, on-the-spot use procedure very easily causes yarn, rope silk wear and rupture.Such rope is all that coiling is deposited after returning to warehouse, how to take a kind of rational method to launch wire rope and carries out the whole process monitoring, and online random tension test does not also have ready-made testing machine solution both at home and abroad.
According to the power construction safety work order, Electric Power Construction Enterprises every year need to be to stringing 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, for safety examination, does not belong to destructive test.One of method that constituent parts adopts at present is to use for reference the disrumpent feelings property of wire rope tensile test method, the test of the sampling section of getting.Mostly in actual applications is near the fag end sampling, sampling limitation problem occurred.These class methods have been destroyed the integrality of whole rope simultaneously, and the fag end shank is processed and with great difficulty do not brought hidden danger, with the purpose of property safety period check, deviates from mutually.Some units also adopt one section wire rope of steel wire clamp chucking to carry out tension test, and this kind of method realized online test objective, still, for the wire rope of cheese inside, owing to can't effectively launching, cause detecting and can't realize.Steel wire clamp Lack of support simultaneously, fully do not hold tactilely to the wire rope surface, process of the test easily causes secondary extrusion to steel wire.
In sum, the current domestic tensile test about wire rope is mainly reflected in the intercepting termination and carries out off-line tensile test aspect, for the wire rope sample of different length, takes to arrange the fixedly mode of hitch point of many places different length wire rope on testing machine; And, for the tensile test method of wire rope, its patent and document achievement also many casting methods, winding method, gland method and direct clamp methods of adopting are separately carried out.Carry out for total length force type wire rope intercepting termination the true safety case that the off-line tensile test can not the objective evaluation wire rope, four kinds of fixture test methods that industry standard is recommended also are the off-line testing that is 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 that is suitable for wire rope of development research, have important engineering significance and theory value.
At present, the solution not yet had.
Summary of the invention
Technical assignment of the present invention is to provide a kind of lineoutofservice signal pull grip of testing machine for above-mentioned deficiency of the prior art, this lineoutofservice signal pull grip of testing machine, by winding method and directly chucking method organic integration, has effectively been realized than the clamping of the not damaged tensile test sample of large-tonnage steel wire rope; Can this clamp structure can be realized the online tensile test of not disrumpent feelings grab sample of wire rope, to checking whole spooling, provide safely effective guarantee; Stationary fixture has designed the both sides fluting, after wearing and tearing, is changed, and can significantly improve the characteristics in fixture life-span.
The technical solution adopted for the present invention to solve the technical problems is: it comprises the S clamp, and described S clamp comprises stationary fixture and moving fixture, and described stationary fixture cross section is V-shaped, the both sides fluting, and described stationary fixture is fixed on base plate; Described moving fixture cross section integral body is convex, pressing surface becomes dimple form, form pipe S shape bending clamp compact space after described moving fixture and stationary fixture combination, described moving fixture is connected with moving clamping fixture seat, described moving clamping fixture seat is connected with the 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, evenly is arranged on respectively in the hole of stationary fixture, between the thick axle of described pier and base plate, by alignment pin, fixes.
Described moving fixture is connected with moving clamping fixture seat by bolt.
Described horizontal sliding oil cylinder comprises two, with moving clamping fixture seat, is connected respectively.
Lineoutofservice signal pull grip of testing machine of the present invention compared to the prior art, there is following outstanding beneficial effect: fully absorbed existing wound form and clamped the tight new application of peace pushing: the bending of S shape, effectively strengthened holding of wire rope touched to area and length, in identical friction material and snap-in force situation, improved the stiction to wire rope; Wire rope through repeatedly crooked coiling, produces the friction pulley skin-friction effect in the space that moving fixture and stationary fixture form, and friction force progressively decays, and moving fixture horizontal sliding snap-in force is corresponding can reduce, and can effectively reduce the compression damage to wire rope; Can this clamp structure can be realized the online tensile test of not disrumpent feelings grab sample of wire rope, to checking whole spooling use safely, provide effective guarantee; Stationary fixture has designed the both sides fluting, after wearing and tearing, is changed, and can significantly improve the fixture life-span.
