Abstract

The utility model discloses a steel wire rope breaking force test fixture. The test fixture consists of an upper member and a lower member which have the same material and specification and are symmetrical to each other, wherein the upper member and the lower member both comprise a big end (1), a small end (2), a clamping bolt (3) and a nut (4). In the utility model, a steel wire rope is wound and compacted in the test process to achieve the aim of fixing the steel wire rope, the phenomena of the damage and slip of the steel wire rope are avoided in the clamping process of the fixture, thus the test reliability and accuracy are improved, the test time is shortened, and the application value is relatively high.

Description

A kind of breaking force of rope test fixture
Technical field
The utility model belongs to the mechanical clamp field, is specifically related to a kind of whether a kind of test fixture of qualified usefulness of wire rope tensile strength that detects.
Background technology
Whether qualified the wire rope tensile test be to weigh wire rope intensity a important indicator; But because former WJ-10 type mechanical type universal testing machine equipment is outmoded; From carrying jig owing to frequent use the retaining part interlock bad and wear phenomenon is serious; Can occur in carrying out wire rope tensile test process that wire rope comes off or from the phenomenon of retaining part fracture, can not in time make accurate judgement to test findings like this influences test, manufacturing schedule again.Need a cover accurately to these phenomenons, practicality, safety, this sleeve clamp is groped and made to test fixture in conjunction with practical experience easily.Prior art be with breaking force of rope test with carry out rupture pull force after the plate test anchor clamps are connected and test, its weak point is if plate grip is too loose, can cause wire rope to come off, if too tightly can cause wire rope to rupture at retaining part.
Summary of the invention
The object of the invention:, a kind of breaking force of rope test fixture of simple and direct practicality is provided for overcoming shortcoming of the prior art.
Technical scheme of the present invention is: a kind of breaking force of rope test fixture; By same material, same specification, mutually to be much of part, part is formed down; Last part, down part includes big end 1, small end 2, fishbolt 3 and nut 4; It is characterized in that, bore the connecting hole 21 of a φ 18mm-20mm on small end 2 tops; Big end 1 processes the winding groove 12 of width 10mm-12mm, is used for lay winding wire ropes; The wireline adapter that bores a φ 10mm near big end 1 end in winding groove 12 penetrates hole 11; Fishbolt 3 passes the screw in the big end 1 with nut 4, and nut 4 compresses wireline adapter and penetrates hole 11, clamps wire rope.
During test, upper and lower of these anchor clamps are inserted connecting hole 21 with pin respectively, be connected on tension tester moving beam and the base, it is suitable to adjust the distance between upper and lower of the anchor clamps again, is wrapped in the wire rope sample on the test fixture then to make an experiment.
Advantage of the present invention and beneficial effect: the utility model reaches the fixedly purpose of wire rope through in process of the test, wire rope being twined and compress; This damages wire rope in clamping process to avoid anchor clamps; And the wire rope phenomenon of skidding; Thereby improved the reliability and the accuracy of test, shortened test period, had bigger using value.
Description of drawings
Fig. 1 is the utility model test fixture structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
With reference to figure 1; This is the planar structure synoptic diagram of a preferred version of the utility model test fixture, and last part, the following part connecting hole 21 that to bore two apertures respectively be φ 18mm are reprocessed out the winding groove 3 of width 10mm; Install fishbolt 3 and nut 4, constitute the whole test anchor clamps.
During test; Upper and lower of these anchor clamps are connected on tension tester moving beam and the base through connecting hole 21 with pin respectively; Suitable the distance adjustment between upper and lower of the anchor clamps again; Be wrapped in the wire rope sample on the winding groove 12 of test fixture, pass wireline adapter then and penetrate hole 11, installation fishbolt 3, tightening nuts 4 backs just can begin test.
These anchor clamps have not only improved the reliability and the accuracy of test, and have shortened test period greatly, have improved work efficiency; Cost is also very low, has bigger using value.
In addition, according to actual needs, the material trademark that the utility model is tested anchor clamps can have certain change, generally uses the higher-strength steel to get final product, and size also can change to some extent, carries out the rupture pull force test with the wire rope that is applicable to different size.
