elevator equipment

Abstract

The elevator installation (1) comprises: a first elevator car (5), a second elevator car (6), a drive mechanical unit (20) and a plurality of traction wheels (21) running by means of the drive mechanical unit (20) Agency (22). In this case, the elevator cars (5, 6) are placed on top of each other by the drive mechanical unit (20) by means of the traction mechanism (22) in the travel space provided for the joint travel of the elevator cars (5, 6) ( 16) Drive in. The traction mechanism (20) is subdivided into a first traction mechanism complex (23) and at least one second traction mechanism complex (24). In addition, at least one adjustment mechanism (35) fixed in position relative to the travel space (16) is provided, the adjustment mechanism is connected between the drive wheel (21) and the second elevator car (6) and the second traction mechanism complex (24 ) to match. In this case, the adjustment mechanism (35) cooperates with the second traction mechanism complex (24) in such a way that the distance (15) between the elevator cars (5, 6) can be varied. The advantage of the elevator installation (1) is that the distance (15) can be adjusted independently of the drive wheels (21), in particular even when the drive wheels (21) are stationary. The adjustment mechanism (35) can in particular have a roller arrangement (36), wherein an adjustable roller (39) of the roller arrangement (36) can be adjusted by an adjustment drive (40) so that the second traction mechanism complex (24 ) of the section (43) between the adjustment mechanism (35) and the second elevator car (6) is changed in length (45).

Description

technical field [0001] The invention relates to an elevator installation having a first elevator cage and at least one second elevator cage, the elevator installation being preferably arranged in an elevator cage frame of the elevator installation. The invention relates in particular to the field of elevator installations designed as so-called double-deck elevator installations. Background technique [0002] An elevator with two elevator cars is known from WO 2005 / 014461 A1, wherein the two elevator cars are coupled to each other in such a way that the two elevator cars can move together in the elevator shaft. In this case, the vertical spacing between the two elevator cars can be adjusted by means of a movement of at least one elevator car relative to the other elevator car. Use an adjustment rope for this. In this case, the ends of the adjustment ropes are fastened to the shaft bottom. A counterweight is suspended from the other end of the adjustment rope. In addition,...
