Background technology
Tension test plays an important role at aspects such as check cable, gold utensil mechanical property, pulling force sensor precision.Particularly in recent years, the Large scale construction of electrical network has proposed higher requirement to the checkability of cable, gold utensil etc.Therefore, improve the efficient of gold utensil, cable tensile strain test, have important economic value.And test coupling arrangement reasonable in design not only can be simplified the program of gold utensil, cable tensile strain test, improves test efficiency, can also increase the security of test.
At present, crimp head (Fig. 1) all is equipped with at the cable two ends of censorship usually, is convenient to hang coupling arrangement.But, different submitted samples, the diameter that the ring of its crimp head varies in size, encircles is different, during tension test, often need change the coupling arrangement of different model.The utility model is intended to design the coupling arrangement that a cover is applicable to different model cable, gold utensil tension test, to improve test efficiency and security.
Summary of the invention
This utility model purpose is: combine existing gold utensil, a kind of cable of the isobaric joint design of cable, gold utensil tension test coupling arrangement, to improve the efficient of gold utensil, cable tensile strain test.This utility model purpose is especially: according to tension test condition and concerned countries examination criteria, design one cover is applicable to cable, the gold utensil tension test coupling arrangement of different model crimp head, simplifies the tension test program, improves test efficiency and security.
The utility model is realized through following technical scheme:
A kind of coupling arrangement that is used for cable, gold utensil tension test is processed by high strength alloy steel, and the utility model characteristic is to comprise thread cap and threaded rod that cooperates with thread cap and bearing pin; An end face at thread cap is fixedly connected with two fixation forks at a distance of certain distance, and on two fixation forks, offers concentric pin shaft hole, and bearing pin cooperates with pin shaft hole; On bearing pin, also offer pin hole, be provided with pin and cooperate with pin hole; Threaded rod is set to thread segment and two sections of no thread segments respectively.
Unthreaded portion on the utility model threaded rod is greater than 100mm.
The utility model fixation fork is made up of two sheet sheet metals, and the spacing between two fixation forks is greater than 5mm.
The front end of the utility model bearing pin and pin all is processed with chamfering.
The beneficial effect of the utility model is to solve key issue: can realize easily gold utensil to be detected, cable and fixture block being linked together, improve the efficient and the security of tension test.
The mechanism of the utility model mainly is according to the requirement to cable, gold utensil pulling strengrth of the size of cable, gold utensil etc. and national standard, and design one cover is applicable to the tension test coupling arrangement of different model cable, gold utensil.
The useful result of the utility model: the cover that this utility model patent relates to is applicable to the tension test coupling arrangement of different model cable, gold utensil; Can let testing crew select suitable coupling arrangement according to cable, the gold utensil of different model; Simplify test routine, improved test efficiency and security.

Embodiment
A kind of coupling arrangement that is used for cable, gold utensil tension test is processed by high strength alloy steel, and the utility model characteristic is the threaded rod 2 and the bearing pin 3 that comprise thread cap 1 and cooperate with thread cap; An end face at thread cap 1 is fixedly connected with two fixation forks 4 at a distance of certain distance, and on two fixation forks 4, offers concentric pin shaft hole 5, and bearing pin 3 cooperates with pin shaft hole 5; On bearing pin 3, also offer pin hole 6, be provided with pin 7 and cooperate with pin hole 6; Threaded rod 2 is set to thread segment and two sections of no thread segments respectively.
Unthreaded portion on the utility model threaded rod is greater than 100mm.
The utility model fixation fork is made up of two sheet sheet metals, and the spacing between two fixation forks is greater than 5mm.
The front end of the utility model bearing pin and pin all is processed with chamfering.
The utility model embodiment comprises following a few step:
(1) chooses high strength alloy steel as rapidoprint.
(2) processing of fixation fork.According to the model of cable crimp head commonly used, gold utensil, two metals that fixed processing is stuck, the distance between sheet metal is slightly larger than the diameter of cable crimp head and gold utensil, greater than 5mm; Fixation fork and thread cap are fixedly connected with to connect and are one.
(3) processing of thread cap.Attacked internal thread on the thread cap, to be connected with the threaded rod on top.
(4) processing of threaded rod.It is cylindric that threaded rod is, and hypomere is processed with screw thread, and epimere does not have screw thread; During tension test, adopt fixture block to clamp threadless part; The length of no thread segment part is greater than 100mm.
(5) processing of bearing pin and pin.The size of bearing pin is processed according to the size of cable crimp head and gold utensil, and the size of pin is processed according to bearing pin, should be less than the bearing pin size; The size of bearing pin and pin hole is processed according to corresponding pivot pin; The front end of bearing pin and pin all is processed with chamfering, is convenient to insert pin hole.During test, bearing pin passes pin shaft hole, is used for fixing, stube cable crimp head, gold utensil, and pin passes the terminal pin hole of bearing pin, prevents cable in the tension test process, gold utensil landing, has increased security performance.
