Problems solved by technology

There are three problems in the current wire rope tensile testing machine for data retrieval: first, they all intercept a section of steel wire rope for off-line tension test, and this method cannot objectively evaluate the real safety status of the steel wire rope for the full-length stressed steel wire rope; second, The four fixture test methods recommended by the national standard are also suitable for off-line breaking tensile test for sampling, and the safety test of the steel wire rope with a large tensile force often causes damage to the clamping end; third, the current steel wire rope tensile testing machine is mostly Single function, mainly for breaking tensile test, no multi-functional, non-damaging, online tensile testing machine for wire rope and its accessories has been found

Abstract

The invention particularly discloses a zero damage multifunctional horizontal type online tension tester which comprises a trough bracket, wherein an upper jaw trolley and a lower jaw trolley are arranged on the trough bracket; both the upper jaw trolley and the lower jaw trolley can slide along the trough bracket; the upper jaw trolley is driven by an actuator cylinder arranged on the trough bracket; the lower jaw trolley is driven by a motor built in the lower jaw trolley; two slippage steering wheels are arranged at two ends of the trough bracket respectively; S-shaped clamping jaw openings are formed in the upper jaw trolley and the lower jaw trolley; both the upper jaw trolley and the lower jaw trolley are arranged between the two slippage steering wheels; the slippage steering wheels can transversely move along the trough bracket. The tension tester fully adopts the technologies and principles of the existing winding method and the direct clamping method and performs organic integration on the basis so as to form the winding clamping method and realize zero damage clamping of a flexible body for online test of large tension safety.

Description

[0001] technical field [0002] The invention relates to a non-damaging multifunctional horizontal online tensile testing machine, which can perform a tensile test with a maximum load of 800kN. Background technique [0003] 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...
