Elevator shaft arranging structure

Abstract

The invention provides an elevator shaft arranging structure which has the advantages of being flexible in layout, convenient to install, exquisite in structure, light in weight, low in running noise and the like. One end of a drag belt (6) is fixed to a load-bearing beam (3). A drag machine (1) is installed on the load-bearing beam (3). The other end of the drag belt (6) is clockwise wound around a counterweight wheel (7) in a downward inclined mode and then clockwise wound around a drag wheel (2) of the drag machine (1) in an upward inclined mode symmetrical about the axis of the counterweight wheel (7), perpendicularly extends downwards, is anticlockwise wound around an under-axle wheel (11), perpendicularly extends upwards, and is finally fixed to a rope head plate (5). The under-axle wheel (11) is connected with a backpack frame (10). The drag wheel (2), the counterweight wheel (7), a counterweight (8), the under-axle wheel (11) and the backpack frame (10) are projected to a horizontal plane to form transverse central lines (5) which are the same straight line. An elevator cage (9) is installed on the backpack frame (10).

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator shaft layout structure that is especially suitable for elevators without a machine room, and is also suitable for elevators with small machine rooms or elevators with machine rooms. Background technique [0002] For traditional wire rope traction elevators, safety regulations stipulate that the ratio of the diameters of the traction sheave, suspension sheave and wire rope must be ≥40 times, and the home elevator must be at least 25 times. Since the diameter of the wire rope is at least 8mm, the diameter of the traction sheave and suspension sheave is relatively large. Large, when the elevator shaft is arranged, either the wheels are not in a straight line, or the shaft space is wasted, and the traction wire rope is twisted, unevenly stressed and worn unevenly, such as the Chinese patent application whose application publication number is CN103523638A.
