[0058] Figure 6 A modified example of the elevator 1 according to one embodiment of the present invention is shown. The layout of the deflector pulleys 33, 34 of this elevator is different from others. Figure 6 It is a side view illustrating the deflector pulleys 33 , 34 and their surroundings as viewed from the center of the lift passage 2 on the lateral inner wall 29 side. Figure 6 Among the reference numerals shown in , the reference numerals that have already appeared indicate the same structural elements as the structural elements denoted by the same reference numerals in other figures. The pulley beam 38 is one form of a pulley bracket, and both ends thereof are fixed to the car guide rail 12 and the hammer-side guide rail 22 . The pulley beam 38 supports the deflector pulleys 33, 34 via bearings.

Abstract

An elevator has a car, a balance weight, a traction sheave, a driving unit, deflector sheaves and main ropes. The balance weight moves in a back region. The traction sheave has a rotational plane disposed in parallel with a back wall in the back region of the uppermost portion of the elevator shaft. The deflector sheaves have rotational planes disposed in parallel with a lateral inner wall of theelevator shaft in a side region. The driving unit is installed on the rotation center line of the traction sheave, and at least a part of the driving unit is disposed in the side region. The direction of the winding plane of the plurality of main ropes is changed between the traction sheave and the deflector sheave.

Description

technical field [0001] The present invention relates to an elevator in which a hoist is arranged inside an elevator passage. Background technique [0002] There is an elevator in which a traction machine (traction machine) is arranged in an elevator shaft (elevator shaft), so that an independent machine room (machine room: machine room) is not provided above the elevator shaft. Most of these elevators are equipped with a hoist on the upper part of the lifting passage. [0003] Jpn.Pat.Appln.KOKAI Publication No. 2001-080843 discloses an elevator in which a hoist is arranged at a position overlapping with a car (car) on a horizontal projection plane. The hoist has a traction sheave around which the main rope is suspended, holding the axis of rotation horizontally. In order to install the bottom surface of the hoist at a position higher than the highest lifting position of the car and the counterweight, the hoist is arranged at the upper end of the rail. [0004] The elevat...
