Abstract
The invention relates to a bridge galvanized steel wire clamping device in a high frequency fatigue test. The clamping device comprises two opposite bases (1), two rivet barrels (2) and two anchors (3), wherein the rivet barrels (2) are arranged in the bases (1); the anchors (3) are arranged in the rivet barrels (2). The bridge galvanized steel wire clamping device in the high frequency fatigue test disclosed by the invention fundamentally solves a problem of time and labor consumption in loading and unloading processes when the high frequency fatigue test is carried out on a bridge galvanized steel wire; in the high frequency fatigue test, a clamped end of the steel wire is not easy to break, thus guaranteeing effectiveness of the test; the clamping device is simple in design and structure, and convenient to use.
Description
Technical field
The fixture that the present invention relates to a kind of bridge zinc-coated wire high frequency fatigue test, is mainly used in solving the time-consuming problem of effort that traditional handling mode brings.Belong to technical field of measurement and test.
Background technology
Bridge need to do high frequency fatigue test with high-strength galvanized steel wire, traditional handling mode is to utilize the bolt of 12 M16 to lock sample, and when handling, a people is difficult to operation, needs many people to coordinate, and the time of a sample of handling more than needing half an hour, not only require great effort but also time-consuming; Meanwhile, traditional handling mode is to adopt bolt that steel wire is held out against, and is easy to make the retaining part of steel wire sample to occur damage, thereby makes steel wire its bare terminal end in the process of high-cycle fatigue fracture occur and cause invalidate the test.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of fixture of bridge high-strength steel silk high frequency fatigue test is provided, this fixture is time saving and energy saving, and the bare terminal end of steel wire can not rupture.
The object of the present invention is achieved like this:
A kind of bridge makes the clamping device of high frequency fatigue test of zinc-coated wire, do high frequency fatigue test for clamping steel wire, be characterized in: described device comprises two pedestals staggered relatively, two riveting buckets and two ground tackles, described two riveting buckets are separately positioned in pedestal and coordinate with base thread, each riveting bucket inside is provided with bellmouth, one end near steel wire on riveting bucket is provided with the first through hole, described the first through hole is through bellmouth, described two ground tackles are separately positioned in two riveting buckets, ground tackle inner hollow and shape are corresponding with the bellmouth in riveting bucket, the capitellate one end of anchor is provided with second through hole corresponding with the first through hole.
A kind of bridge of the present invention makes the clamping device of high frequency fatigue test of zinc-coated wire, its riveting bucket is cylindrical.
A kind of bridge of the present invention makes the clamping device of high frequency fatigue test of zinc-coated wire, also comprise jacking block, and described jacking block is arranged in riveting bucket and offsets with one end of ground tackle major part.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of bridge of the present invention makes the clamping device of high frequency fatigue test of zinc-coated wire, 1. fundamentally solved steel wire in the time carrying out high frequency fatigue test, the difficult problem that cargo handling process is wasted time and energy; 2. in high frequency fatigue test, the bare terminal end of steel wire is difficult for rupturing, and has ensured the validity of test; 3. this holding device design is simple in structure, easy to use.

Embodiment
Referring to Fig. 1-4, the present invention relates to the clamping device that a kind of bridge zinc-coated wire does high frequency fatigue test, it comprises two pedestals 1 staggered relatively, two riveting buckets 2 and two ground tackles 3, between two pedestals 1, be provided with steel wire 5, described two pedestals 1 are provided with blind hole 1.1 in relative end, the inwall of described blind hole 1.1 is provided with internal thread 1.2, described riveting bucket 2 is cylindrical, inside is provided with bellmouth 2.3, and on riveting bucket 2, be provided with external thread 2.1, riveting bucket 2 is equipped with in the blind hole 1.1 of pedestal 1 by external thread 2.1 and internal thread 1.2, riveting bucket 2 is provided with the first through hole 2.2 perpendicular to the axis of riveting bucket 2 near one end of steel wire 5, described the first through hole 2.2 is through bellmouth 2.3, described two ground tackles 3 are separately positioned in two riveting buckets 2, the truncated cone-shaped that ground tackle 3 is hollow, shape is corresponding with the bellmouth 2.3 in riveting bucket 2, one end of ground tackle 3 microcephalies is provided with second through hole 3.1 corresponding with the first through hole 2.2, described jacking block 4 is arranged on the bottom of blind hole 1.1, and offset with one end of ground tackle 3 major parts.
Described ground tackle 3 mainly contains diameter 5.0mm ~ 5.3mm series and diameter 7mm series specification.
Installation process: first by staggered relatively two pedestals 1, two ground tackles 3 are put into respectively to the bellmouth 2.3 of two riveting buckets 2, and make the first through hole 2.2 corresponding with the second through hole 3.1, now the first through hole 2.2 and the second through hole 3.1 through first group by one end of steel wire 5, the other end of steel wire 5 passes the first through hole 2.2 and second through hole 3.1 of second group, then two riveting buckets 2 are put into respectively to blind hole 1.1 and tightened, after being screwed to a certain degree, due to the effect of jacking block 4, the truncated cone-shaped ground tackle 3 of hollow starts distortion and moves to the direction of steel wire 5, at this moment, the second through hole 3.1 starts not corresponding with the first through hole 2.2, steel wire 5 locking that is stuck, finally start to carry out high frequency fatigue test.
