The specific embodiment
Fig. 1 is a kind of implementation of rope longitudinal travel collocation structure, and device comprises rotating cylinder 1 and anchor shaft 2, and rope 3 windings are on rotating cylinder 1, and rope a bit is fixed on the rotating cylinder, and anchor shaft is located at rotating cylinder and puts 4 nearer ends apart from the rope pulling; The anchor shaft outside face is carved with screw thread 5, one ends and is fixed on the fixation wall, and the other end and rotating cylinder are spirally connected.See from left to right that along the anchor shaft axis screw thread on the anchor shaft is spiral in a clockwise direction, and the rope on the rotating cylinder is pressed C.C.W. direction one circle one circle screw-casing on rotating cylinder.Wherein, the spacing of screw thread equates with the pitch of turn of rope, is d.
When as shown in the figure when pulling point 4 is pulled out rope, rope can drive rotating cylinder and rotate by the clws direction, and rotating cylinder whenever turns around, and rope reduces by a circle on rotating cylinder, and rope pulling point just moves right on rotating cylinder, and mobile distance equals the pitch of turn of rope.Simultaneously, because the direction that rotating cylinder rotates is consistent with the hand of spiral on the anchor shaft, rotating cylinder precession anchor shaft.Rotating cylinder whenever turns around, with regard to the axially left-handed distance of advancing a flight pitch of relative fixed.Like this, rotating cylinder rotates a circle, and the relative rotating cylinder of rope pulling point moves to right apart from d, and rotating cylinder relative fixed axle moves to left apart from d, and two places offset, and the distance that rope pulling point relative fixed axle moves is 0, guarantees that rope spurs on same vertical curve all the time.
When rotating cylinder rotated counterclockwise, rope changed rotating cylinder over to, and the relative rotating cylinder of rope pulling point is moved to the left; Because the direction that rotating cylinder rotates is opposite with the hand of spiral on the anchor shaft, rotating cylinder screws out anchor shaft, relative fixed axially moves right, the distance that both direction moves offsets, the distance that rope pulling point relative fixed axle moves is 0, guarantee that rope spurs all the time on same vertical curve, a rope has under the situation of two (turnover) ports simultaneously, as shown in Figure 2, rotating cylinder rotates, and rope one end produces, and an end changes over to, the equal in length that produces and change over to, the position of the pulling point relative fixed axle at two ends all can not change.
Fig. 3 is the another kind of implementation of rope longitudinal travel collocation structure, the changing of design of rotating cylinder is the plurality of sections that comprises that diameter is different, its axle center is on same straight line, all be arranged with rope on each section of rotating cylinder, rope a bit is fixed on the rotating cylinder, on each section, the direction of rope winding and the pitch of turn of rope are all identical.Anchor shaft is located at rotating cylinder and puts 4 ends far away apart from the rope pulling.See from left to right that along the anchor shaft axis screw thread on the anchor shaft is spiral in a clockwise direction, and the rope on the rotating cylinder is pressed C.C.W. direction one circle one circle screw-casing on rotating cylinder.Wherein, the spacing of screw thread equates with the pitch of turn of rope, is d.
When as shown in the figure when pulling point 4 is pulled out rope, rope can drive rotating cylinder and rotate by the C.C.W. direction, and rotating cylinder whenever turns around, and rope reduces by a circle on rotating cylinder, and rope pulling point just is moved to the left on rotating cylinder, and mobile distance equals the pitch of turn of rope.Simultaneously, because the direction that rotating cylinder rotates is opposite with hand of spiral on the anchor shaft, rotating cylinder back-out anchor shaft.Rotating cylinder whenever turns around, and axial dextrorotation goes out the distance of a flight pitch with regard to relative fixed.Like this, rotating cylinder rotates a circle, and the relative rotating cylinder of rope pulling point moves to left apart from d, and rotating cylinder relative fixed axle moves to right apart from d, and two places offset, and the distance that rope pulling point relative fixed axle moves is 0, guarantees that rope spurs on same vertical curve all the time.When rope changed over to and rotates, its mode of motion was similar when producing, and direction is opposite, can guarantee still that finally rope spurs on same vertical curve all the time.A rope has under the situation of two (turnover) ports simultaneously, and as shown in Figure 4, rotating cylinder rotates, and rope one end produces, and an end changes over to, the equal in length that produces and change over to, and the position of the pulling point relative fixed axle at two ends all can not change.
The various piece that diameter does not wait on the rotating cylinder, cireular frequency but is identical during rotation, so the longitudinal travel that they produced equates that distinguish the rotating cylinder part that only is different-diameter, the length difference of pulling was proportional when the rope on it enclosed in rotation one.
