Wire Rope Tensile Testing Machine Fixtures

Abstract

The invention discloses a clamp of a steel wire rope tension test machine and belongs to a clamp. The clamp structurally comprises an S-shaped clamp, wherein the S-shaped clamp comprises a fixed clamp and a moveable clamp; the section of the fixed clamp is V-shaped; the two sides of the fixed clamp are grooved; the fixed clamp is fixed on a bottom plate; the whole section of the moveable clamp is convex; a pressed surface is shallowly concave; the moveable clamp and the fixed clamp are combined to form a round tube S-shaped bending clamping space; the moveable clamp is connected with a moveable clamp seat; the moveable clamp seat is connected with a horizontal pushing oil cylinder; the horizontal pushing oil cylinder is arranged on the bottom plate. The clamp organically integrates a winding method and a direct clamping method to effectively realize clamping of a test sample of a non-damage tension test of a large-tonnage steel wire rope. The clamp structure can realize non-broken on-line random sampling tension test of the steel wire rope and provides an effective guarantee to inspect whether the whole steel wire rope is safe or not. The two sides of the fixed clamp are grooved, so the clamp has the characteristics that the grooves can be exchanged after being worn; and the life of the clamp can be prolonged exponentially.

Description

technical field [0001] The invention relates to a clamp, in particular to a clamp for a steel wire rope 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...
