Problems solved by technology

[0012] However, in the hoist disclosed in the above-mentioned Patent Document 1, no consideration is given to how to realize a rare earth-free permanent magnet motor, so as the price of rare earth materials rises sharply, the cost of the hoist may increase significantly

Embodiment Construction

[0057] An embodiment of the present invention will be described below with reference to the drawings.

[0058] First, refer to Figure 6 and Figure 7 The overall structure of the elevator without a machine room which is the object of the present invention will be described.

[0059] Figure 6 It is an overall perspective view of an elevator without a machine room as an object of the present invention, Figure 7 It is a plan view (sectional view of a hoistway) of an elevator without a machine room which is the object of the present invention.

[0060] Such as Figure 6 As shown, in this elevator, the winch 30 is arranged in the hoistway, and the counterweight 2 is arranged in the gap behind the elevator car 1 .

[0061] Hoist 30 is made up of motor 4 and sheave 5, in order to reduce the torque that motor 4 needs to have to realize the miniaturization of hoist 30, adopted the sling winding mode of 2:1, at this moment, the winding amount of hoist 30 is elevator Twice the a...

Abstract

PROBLEM TO BE SOLVED: To provide an elevator device that includes a rare-earth-less magnet motor and also includes a hoisting machine making no increase in volume of a hoistway.SOLUTION: An elevator device is characterized in that a skeleton part has the same width W, a sheave diameter is smaller, and a hoisting machine includes a ramp pulley 23 against which a main rope wound around the smaller-diameter sheave 5 abuts and which guides the rope to nearby the position of the main rope before the diameter reduction.

Description

technical field [0001] The invention relates to an elevator installation having a hoist for raising and lowering an elevator car. Background technique [0002] In general, elevators are constructed so that the elevator car is connected by slings to counterweights whose weight is balanced with a load approximately half the rated load of the elevator car, and the hoisting sheave is connected directly to the electric motor. The sling is hoisted, so that the elevator car and the counterweight suspended in the shape of a bucket are raised and lowered in the hoistway. [0003] In addition, the hoist uses a so-called traction drive, which transmits torque to the rope via friction between the rope pulley and the rope wound around the rope pulley. [0004] In recent years, in order to reduce the volume of the hoistway, elevators without a machine room in which the hoist is installed in the hoistway have gradually become mainstream elevators. [0005] In the elevator without a machi...
