Abstract
The invention discloses an auxiliary device for tension test of a three rows of roller chains. The auxiliary device comprises a coupling part and a clamping part. The front end of the coupling part is provided with three parallel connecting square holes and a connecting pin through hole which penetrates through the connecting square holes. The lengths, the widths and the depths of the three connecting square holes match one end of each of the three rows of roller chains so that an inner chain plate end can be inserted into the three connecting square holes and furthermore the inner chain plate end is connected with the connecting part of the auxiliary device in a shaft connecting manner through a connecting pin. After the auxiliary device for the tension test is connected with the three rows of roller chain samples, a requirement for the axial tension test of three rows of roller chains for an elevator can be satisfied so that the three rows of roller chains for the elevator can reasonably and stably perform the tension test which satisfies a GB/T 1243 standard requirement on a universal material tester.

In order to solve above-mentioned technical problem, the technical solution used in the present invention is as follows:
A kind of auxiliary device for triplex roller chain tension test, the sample of triplex roller chain comprises several three-row roller chain elements joint, its two ends are inner plate end, described auxiliary device is for coupling the inner plate end at triplex roller chain two ends, described auxiliary device includes connection part and clamping part, described clamping part can mate and is held on the hydraulic chuck of testing machine, the front end of described connection part is provided with three side by side and couples square hole, and it is provided with three the connecting link pin through holes coupling square hole running through described, the pin diameter of described connecting link pin through hole and described triplex roller chain matches；Described three couple the inner plate end that the length and widths of square hole, the degree of depth and spacing all save with the three-row roller chain element of described triplex roller chain one end and match so that the inner plate end of described three-row roller chain element joint can be inserted in described three, and to couple square hole interior and the inner plate end axle ground connection of described triplex roller chain is connected in the connection part of described auxiliary device by connecting link pin.
Described auxiliary device makes preferably with 42CrMo structural alloy steel, makes integral hardness reach 38～44HRC by modifier treatment, to obtain the combination property of good intensity and toughness.Described connection part front end offer described three couple square holes along inner plate short transverse wall thickness and described three couple outer ends, square hole both sides wall thickness more than 1/2nd of inner plate height, to ensure the integral rigidity of this auxiliary device.
The diameter of described connecting link pin is identical with the pin diameter of described triplex roller chain, and hardness is preferably up to reach 58～60HRC.
The assistant apparatus structure of the present invention is reasonable, ingenious, can stablize and reasonably couple with triplex roller chain tensile sample two ends, then pass through clamping part matchingly, stably with the hydraulic chuck of general material test machine to clamp and couples, thus stably accurately obtaining the stretching data of sample.
This assistant apparatus structure is reliable, easy for installation, rigidity is high, and those of ordinary skill can complete assembling and test operation after simple training；
Use this auxiliary device that the test failure caused because of the local damage of frock, lifting test work efficiency when testing, can be prevented effectively from.
This auxiliary device and triplex roller chain segment two ends connecting mode are equal to the connecting mode of chain link self, therefore adopt this device to carry out pull test and can better simulate roller chain stress under actual condition.
