STAND AND METHOD FOR TESTING ROPES Russian patent published in 2019 - IPC G01N3/32 

FIELD: test equipment.

SUBSTANCE: invention relates to the field of testing equipment, in particular to devices for testing ropes, namely, stands for testing ropes for endurance. Stand contains a support frame, at least two rope fastening assemblies, at least one of which is movable, a mechanism that enables the rope fastening assembly to move, device for tensioning the rope, at least two rotating synchronously in opposite directions of the drum, each of which is equipped with at least one set of pulleys made with the possibility of rotation in the places of their fastening on the drums, a mechanism for adjusting the distance between the centers of rotation of the drums, a device for synchronizing the rotation of the drums, at least one engine with a transmission. One end of the rope is fixed in a fixed rope attachment, the rope is passed between the pulleys located on the drums, the second end of the rope is fixed in the movable rope attachment, the rope is tensioned using a rope tensioner, and the drums are driven by means of an engine with a transmission and a synchronization device for rotating the drums in such a way that the drums synchronously rotate in opposite directions at a certain speed and roll pulleys along a rope, the distance between the centers of rotation of the drums using the mechanism for adjusting the distance between the centers of rotation of the drums is chosen in such a way as to minimize the amplitude of movement of the movable rope attachment in the mechanism that provides this feature.

EFFECT: reducing the amount of time spent on testing the ropes, while reducing energy consumption.
