The wire rope is typically reeled in and out by a hoisting mechanism. At present, a single-row rope main winch is commonly used in the field of rotary drilling rigs. The studio is along with wire rope's transfer, and wire rope rolls to the another side of reel from one side of reel, and wire rope twines the incident angle of pulley and can take place very big change, and wire rope twines the pulley and has higher requirement to the incident angle. Therefore, the rotary drilling rig needs a rope guide mechanism to guide the steel wire rope, so that the incident angle of the rotary drilling rig meets the use requirement. At present, the guide rope mechanism of the rotary drilling rig mainly has two types of sliding and swinging.
The sliding rope guide mechanism enables the steel wire rope to slide on a longer shaft through the sliding bearing arranged on the inner side of the pulley so as to meet the requirement of an incident angle when the steel wire rope moves from one side of a winding drum to the other side of the winding drum, but the mechanism needs to be bent in the working process because the stress angle is not vertical to the pulley, so that the sliding bearing in the pulley is easy to wear into a horn mouth shape and fails.
The swinging mechanism can meet the requirement of an incident angle when the steel wire rope moves from one side of the winding drum to the other side by swinging around the hinged seat welded on the drill mast, the mechanism can ensure that the stress direction of the pulley and the steel wire rope is always vertical, but the occupied space is larger, and other steel wire rope guide mechanisms cannot be arranged in the swinging space.
