[0084] Image 6 It is a front view showing the outline of the ends of the car position adjusting ropes in the second embodiment of the double-deck elevator according to the present invention. exist Image 6 In , parts having the same structure as those of the first embodiment are denoted by the same symbols, and repeated descriptions thereof are omitted. exist Image 6 Among them, the hydraulic cylinder 25 a is configured to drive the fixing member 32 supporting the spring as the elastic body 19 . According to the structure of this embodiment, since the vibration amplitude generated by the repeated load acting on the elastic body 19 only needs to be able to cope with the fluctuation of the load, the required strength of the elastic body 19 can be reduced, and the size of the elastic body can be reduced. . The correction of the position of the elevator car can obtain the same effect by adopting the same structure as that of the above-mentioned embodiment. This embodiment c...

[0086] Figure 7 It is a front view showing the outline of the ends of the car position adjusting ropes in the third embodiment of the double-deck elevator according to the present invention. Figure 7 The illustrated fixed member moving device 25a is configured to drive a fixed member 26a suspending a wire rope as the car position adjusting rope 17 by means of a ball screw device 25a. The ball screw shaft 33 is passed through the fixing nut 34 for the ball screw fixed on the fixing member 26a, and the rotational torque is converted into the linear motion of the ball screw by the ball screw driving device 35 (such as a servo motor), thereby passing the ball screw shaft 33 to correct the variation of the elevator car position. The detection of the position of the elevator car can be accomplished by the same structure as that of the above-mentioned first embodiment. Since the ball screw device can be driven by electricity, it does not require the use of pressure fluid, that is...

Abstract

Provided is a double-deck elevator. In the double-deck elevator, elevator cars are arranged in an elevator car frame in the vertical direction and are suspended via end portions of ropes. The double-deck elevator can prevent the occurrence of unbalance loading when fixing members for fixing the end portions of the ropes are moved. The double-deck elevator comprises an elevator car frame (2), an upper car (12), a lower car (13), a driving device (11) for adjusting the car position and a rope-shaped body (17). In the double-deck elevator, one end or two ends of the rope-shaped body (17) are suspended down from the fixing members (26a, 26b) and are mounted on the elevator car frame (2) via fixing member moving units (25a, 25b) which allow movement of the fixing members (26a, 26b). In addition, the double-deck elevator has guide mechanisms (28, 29). When the fixing members (26a, 26b) are driven to move by the fixing member moving units (25a, 25b), the guide mechanisms (28, 29) guide the movement of the fixing members.

Description

technical field [0001] The invention relates to a double-deck elevator with a plurality of elevator cars within an elevator car frame. Background technique [0002] In existing double-deck elevators in which the upper and lower cars are configured to be movable, it is known that a driving device is arranged on the upper part of the elevator car frame, and the driving device is connected with the car below the upper car by a rope. An elevator that connects the pulleys and the pulleys installed under the car of the lower car. In the above-mentioned structure connecting the driving device and the pulley by a rope, as the load changes, the rope will be elongated, and the floor position of the elevator car will change due to the elongation of the rope. The plan for correcting the position of the compartment. For example, Patent Document 1 discloses a double-deck elevator having the above-mentioned structure. [0003] Patent Document 1 Japanese Patent Laid-Open No. 2007-331871 ...
