Description

Technical Field

[0001] The invention relates to the technical field of endless rope transmission, in particular to a supporting mechanism and a rope gripper for an endless rope. Background Art

[0002] Endless rope transport is a continuous transport method that uses a closed circular steel wire rope to pull a mine car to transport materials. This transport method has a driving wheel at one end of the transport tunnel and a tail wheel at the other end. The steel wire rope is passed around the driving wheel and the tail wheel to connect them into a circular endless traction group. The electric motor drives the driving wheel to rotate, and uses friction to drive the steel wire rope to move continuously, thereby realizing the transportation of materials.

[0003] In long-distance endless rope transmission, even if the endless rope is in a tensioned state, it will still sag due to its own weight. This sagging of the endless rope, on the one hand, affects the uniformity and timeliness of the power transmitted by the endless rope.
