A kind of single wrap guide wheel device of traction elevator, comprise towing machine, traction sheave, hoist ropes, track adjusting wheel and horizontally disposed transverse base, described towing machine is fixed on the upper surface of base one end by longitudinal bearing, the rotating shaft of towing machine and traction sheave transmission, described base is made up of the upper base plate connecting by reinforced rib and lower seat board, described track adjusting wheel comprises with traction sheave axially parallel and is positioned at conplane A track adjusting wheel and B track adjusting wheel, the horizontal surface projection of described B track adjusting wheel is between traction sheave and the horizontal surface projection of A track adjusting wheel, described A track adjusting wheel is rotationally connected with upper base plate, described B track adjusting wheel is rotationally connected with lower seat board, hang down with respect to the outside of B track adjusting wheel from traction sheave in described hoist ropes one end, the other end is walked around edge on traction sheave with single successively around mode, edge under B track adjusting wheel, in A track adjusting wheel, behind edge, hang down with respect to the outside of B track adjusting wheel from A track adjusting wheel.
The center of circle of described B track adjusting wheel and traction sheave distance in the horizontal direction equals the radius sum of the two, makes the hoist ropes between B track adjusting wheel and traction sheave be vertical state.
Described upper base plate and lower seat board are made up of two horizontally disposed transverse slats respectively, on described transverse slat, be respectively equipped with bolt hole, the wheel shaft two ends of described A track adjusting wheel and B track adjusting wheel are fixedly connected on transverse slat by U-bolt respectively, the wheel shaft of described A track adjusting wheel is connected in upper base plate upper surface, and the wheel shaft of described B track adjusting wheel is connected in lower seat board lower surface.
Described upper base plate upper surface is also provided with protective cover, and described protective cover one end is positioned at the outside of A track adjusting wheel with respect to B track adjusting wheel, and other end extension approaches longitudinal bearing, is buckled in A track adjusting wheel and B track adjusting wheel top.
The upper base plate of described A track adjusting wheel both sides is connected with respectively the hoist ropes anti-falling limit bar parallel with wheel shaft with on the lower seat board of B track adjusting wheel both sides.
The utility model advantage is compared with prior art:
One, with two track adjusting wheel composition guiding wheels, hoist ropes is walked around and is positioned at conplane traction sheave and guiding wheels increase span around mode with single, hoist ropes is stressed evenly, for different span requirements, only need the simple position of adjusting guiding wheels, without accurate Calculation, significantly reduce the difficulty of manufacturing and installing;
Two, traction sheave grooving together with distinguishing a needs in track adjusting wheel, compares the multiple tracks grooving that compound-wound track adjusting wheel and traction sheave adopt, and axial width significantly reduces, and the average price of traction sheave and track adjusting wheel significantly reduces, and effectively saves the manufacturing cost of elevator.
