Abstract

The invention discloses a horizontal online tension tester belonging to testers. The horizontal online tension tester structurally comprises a tension test channel frame, an upper jaw trolley, a lower jaw trolley, a tension power oil cylinder and two slidable steering wheels, wherein guide rails are arranged at the front side and the rear side of the upper part of the tension test channel frame respectively, the lower parts of the upper and the lower jaw trolley are arranged on the guide rails respectively, the two slidable steering wheels are arranged at the left side and the right side of the tension test channel frame respectively, the upper jaw trolley is connected with a main oil cylinder tension frame, the main oil cylinder tension frame is connected with the tension power oil cylinder, and the lower jaw trolley is connected with the guide rails through a motor drive mechanism. Compared with the prior art, the horizontal online tension tester disclosed by the invention has the characteristics of online testing, zero damage in clamping of a workpiece, and the like, thereby having good popularization and application value.

Description

technical field [0001] The invention relates to a testing machine, in particular to a horizontal online tensile testing machine. Background technique [0002] According to GB / T8358-2006 "Steel Wire Rope Breaking Tensile Test Method", there are four clamping methods for steel wire rope specimens: casing pressure method, casting method, direct clamping method and winding method. The above-mentioned methods all adopt the sampling detection method, that is, a section is intercepted on the basis of the existing whole rope, and a breaking tensile test is carried out. The specific requirement of this test for the clamps at both ends is to prevent loosening and slipping of the clamping parts of the specimen during the test process, and whether the clamping parts of the specimens are damaged has not been clearly proposed and studied. This type of method is suitable for the detection and acceptance of new ropes. For the steel wire ropes that have been used, the performance of the mid...
