The invention provides a test device for abrasion of multilayer winding wire rope-pulley, and the test device is a combined test device capable of being used for simulating the crane lifting and the actual operating condition of a luffing system, performing the multilayer winding on the wire rope, and testing the abrasion of the wire rope-pulley. The test device comprises a test bench and an electric control and data acquisition processing device, wherein an operation platform (upper computer) in a control chamber is used for performing the centralized operation and control and is used for acquiring the testing data and performing the data treatment; in the test bench, a winding reel of a multilayer winding device is a double broken line type multilayer winding reel; a pulley block bracket is moveable and is used for adjusting an deflection angle for guiding the wire rope to enter into the winding reel; and a high-speed shaft end of a reducer of the multilayer winding device is connected to an electric eddy current dynamometer for simulating a load. The test device has high test efficiency, the data acquired from the test is accurate, and the test device can be used for researching the crane wire rope multilayer winding, the multilayer winding wire rope fatigue failure test, the multilayer winding pulley fatigue failure test, and the like.
Description
technical field [0001] The invention relates to a wear test device, in particular to a steel wire rope-pulley wear test device. Background technique [0002] With the continuous increase of hoisting cargo units, hoisting machinery is also constantly developing in the direction of large-scale, high-efficiency, and automation. How to realize the smooth winding of large hoisting height and multi-rate steel wire rope is a hot spot in the research of multi-layer winding system at present. The reasonable selection, safety and service life of the steel wire rope of the double-broken multi-layer winding drum, the surface hardness of the pulley groove, the value of the diameter ratio of the pulley to the wire rope, the winding speed of the drum, the safety factor and the wear and tear of the wire rope There is still no clear answer to questions such as the relationship between life expectancy, and there is no basis for experimental demonstration. Simulate the actual operating condi...
