The counterweight guide wheel 21 is positioned below the counterweight diverting pulley 24, and the center axis of the counterweight guide wheel 21 is arranged perpendicular to the center axis of the counterweight diverting pulley 24, so that the mutual interference between the wire ropes wound around the counterweight guide wheel 21 and the counterweight diverting pulley 24 can be avoided, and the rope winding mode is more compact. The center axis of the counterweight guide wheel 21 is parallel to the center axis of the hoisting machine 1, and the counterweight guide wheel 21 and the hoisting machine 1 partially overlap in a planar orthographic projection. The arrangement mode is compact, the space is utilized to the maximum extent, and the occupation of vertical space is reduced.
The counterweight frame 3 is located in the elevator shaft and is disposed below a counterweight traction mechanism in the machine room. The top of the counterweight frame 3 is provided with a first pulley 22 and a second pulley 23 in parallel, on one hand, the steel wire rope realizes the traction effect on the counterweight frame 3 by winding the first pulley 22 and the second pulley 23, and on the other hand, the steel wire rope obtains the required suspension ratio of the elevator by winding the first pulley 22, the counterweight diverting pulley 24 and the second pulley 23.
The car traction mechanism comprises a car diverting pulley 41, the car diverting pulley 41 is arranged at the center position of the machine placing beam 5 along the length direction, the central shaft of the car diverting pulley 41 is vertical to the extending direction of the length of the machine placing beam 5, and the car diverting pulley 41 is used for changing the rope winding direction of a steel wire rope in the car traction mechanism.
The car traction mechanism further comprises a car rope hitch plate 42, and the car rope hitch plate 42 is arranged on the machine placing beam 5 and is positioned between the wall body and the car diversion sheave 41 and used for fixing the end part of a steel wire rope which is wound out of the car traction mechanism.
The counterweight rope hitch plate 25 is arranged on the counterweight rope hitch beam 6 and used for fixing the end part of the steel wire rope wound out of the cage traction mechanism.
Further, the machine placing beam 5 and the counterweight rope end beam 6 are all H-shaped steel, strength requirements can be met, and compared with the common I-shaped steel channel steel, the machine placing beam and the counterweight rope end beam are small in size, low in processing and transportation cost and high in cost performance. In this embodiment, put quick-witted roof beam 5 and include two H shaped steel, the parallel interval arrangement of two H shaped steel, press from both sides to locating between two H shaped steel to counter-weight leading wheel 21, install in the bottom end face of H shaped steel to counter-weight leading wheel 21, car diverting pulley 41 installs the up end at H shaped steel and is located between two H shaped steel to make arrangement compact, save space.
