Abstract

The invention relates to the technical field of wire ropes, especially to a wire rope fatigue testing apparatus and method. The wire rope fatigue testing apparatus comprises an apparatus bench and first rectangle frame bodies arranged on the apparatus bench, wherein the first rectangle frame bodies are respectively arranged on two ends of the apparatus bench and both provided with a rotatable directive wheel; the wire rope fatigue testing apparatus also comprises a draw gear which is fixedly arranged on the first rectangle frame bodies; and the wire rope fatigue testing apparatus further comprises a movable pulley rotating device. According to the invention, through arrangement of the draw gear, the draw gear can tighten the wire rope through dragging, kinetic friction occurs between a movable pulley and the wire rope, so friction between the wire rope and the pulley under the action of a certain tensile force can be authentically simulated; the apparatus has a simple structure and can automatically adjust the tensile force of the wire rope; and since the wire rope is not connected with a heavy object, the problem of potential safety hazards does not occur during usage. The testing method provided by the invention can authentically simulate the friction between the wire rope and the pulley under the action of a certain tensile force and comprises simple steps.

Description

technical field [0001] The invention relates to the technical field of steel wire ropes, in particular to a steel wire rope fatigue testing device and method. Background technique [0002] In actual use, the steel wire rope will inevitably produce relative motion with pulleys, traction wheels and other devices, resulting in sliding friction. In fact, sliding friction is an important factor for the early breaking of wire ropes. Therefore, in the actual use of the wire rope, it is seldom due to the fatigue life of the wire rope, which leads to the scrapping and replacement of the wire rope, and more is caused by the sliding friction between the wire rope and the pulley, traction wheel and other devices. At present, the steel wire rope fatigue test is to repeatedly move the steel wire rope around the pulley, so that the steel wire rope and the pulley are constantly rolling relative to each other to test the fatigue life of the steel wire rope. This test method is an abstract ...
