Embodiment Construction

[0032] Image 6 , Figure 7 , Figure 8 An auxiliary device 20 for tensile testing of a three-row roller chain is shown, Figure 4 , Figure 5 It shows the auxiliary device of the tensile test and the assembly diagram of the three-row roller chain sample. The three-row roller chain sample contains several three-row roller chain unit sections 10, and the two ends of which are inner chain plate ends 11. The auxiliary device 20 is used to connect the inner chain plate ends 11 at both ends of the three-row roller chain. The auxiliary device 20 includes a coupling part 21 and a clamping part 22. The clamping part 22 can match the clamping part Hold on the hydraulic chuck of the testing machine, the front end of the coupling part 21 is provided with three coupling square holes 211 side by side, and is provided with a coupling pin shaft through hole 212 passing through the three coupling square holes 211, The diameter d of the pin shaft 103 of the described connecting pin shaft t...

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.

Description

technical field [0001] The invention relates to an auxiliary device for a mechanical detection test, in particular to an auxiliary device for a tensile test. Background technique [0002] Nowadays, elevators are more and more widely used in people's lives, and it is also very important to test the performance of the three-row roller chain dedicated to elevators. However, the existing general-purpose material testing machine lacks an auxiliary device dedicated to the three-row roller chain used in elevators, which makes it difficult to perform this type of test and is prone to errors. [0003] In general, roller chain pull tests are performed on general materials testing machines with hydraulic chucks. Due to the need to meet the requirements of the GB / T1243 standard for the tension test connection of the roller chain, the chain cannot be directly clamped on the hydraulic chuck. The accuracy of the test. [0004] figure 1 , figure 2 , image 3 Shows the structure of th...
