DEVICE AND METHOD FOR TESTING LOAD-CARRYING PROPERTIES OF WIRE ROPE FOR FRICTION HOIST

摘要

A device and method for testing load-carrying properties of a wire rope for a friction hoist. The testing device comprises two loaded hydraulic cylinders (1), a hydraulic cylinder locating platform (2), a wire rope locating platform (6), a surrounding angle locating device (4) provided on a linear segment of the wire rope locating platform (6) in the vertical direction, and a plurality of wire rope locating devices (5) provided on an arc segment of the wire rope locating platform (6) in the radial direction. A practical friction hoisting process is simulated on the basis of the principle of driving a wire rope (3) and a two-way hydraulic pump (5-b) by the double-acting hydraulic cylinders (1) to provide load damping, the working conditions such as overload and secondary overload can be simulated for the loading of the hydraulic cylinders (1), and a creeping process of the wire rope (3) in a surrounding arc can be simulated for the providing of the load damping by the hydraulic pump (5-b), so that the load-carrying properties of the wire rope (3) can be accurately tested, and the test requirements of friction hoists having different drum diameters and different surrounding angles can be met.
