Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator device, and more particularly to a guide device for guiding a lifting operation within an elevator passage of an elevator elevator basket. Furthermore, the present invention relates to a guide device for an elevator elevator cage that uses three guide rails to suppress lateral vibration of the elevator basket.

As is well known in the prior art, the elevator cage of an elevator is guided by a guide rail in an elevator passage.
Conventionally, an elevator basket is provided with guide roller units formed of three rollers or wheels on both sides of the floor of the elevator basket, and the same guide roller units are provided on both sides of the ceiling portion. The guide rail is usually formed in a T-shape, and the T-leg is provided so as to project toward the elevator cage side. The three rollers of each guide roller unit contact the end surface and both side surfaces of the T-shaped leg portion of the guide rail to guide the lifting operation of the elevator basket. In a normal case, the combination of two guide rails and a guide roller unit can guide the lifting / lowering operation of the lifting / lowering cage in a sufficiently smooth and stable state.

However, in the case where the elevator cage is long, such as when the elevator cage has a depth structure such as a door provided on both sides, the lateral direction of the elevator cage Vibration may occur, and this tendency becomes particularly strong when the elevator cage is operated at high speed.

Embodiment An elevator apparatus according to a preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, the elevator basket 2 is provided in an elevator passage 4 so that it can be raised and lowered. In the illustrated example, the elevator basket 2 is configured to have doors for getting in and out on both sides in the front-rear direction, and one door is provided in the front portion 6. A plate-shaped member 8 functioning as a sill and a toe guard is attached to the front portion 6.
It is formed to extend downward from the floor 10 of the elevator basket 2 in the elevator passage 4. The wall member 12 on the front side in FIG.
Are partially cut away to show the internal structure. The portion 14 is a corner portion in the vertical direction where the front side portion 6 in which the door is arranged and the side wall adjacent to the front portion 6 are joined. In the hoistway, a pair of main guide rails 16 are arranged parallel to the vertical axis of the hoistway. The main guide rails 16 are located opposite to both sides of the elevator basket 2. Each of the guide rails 16 is formed in a T-shape in cross section, and the T-shaped legs extend toward the opposite side walls of the elevator basket 2.
Forming eighteen. In addition, these main guide rails 16
Is located at a substantially intermediate position in the front-rear direction of the elevator basket 2,
The T-shaped head is fixed to the wall surface of the hoistway by a bracket (not shown).

A structural beam 28 is provided below the floor 10 of the elevator basket 2, and the structural beam 28 includes three rollers 30, 3
A guide roller unit consisting of 2 and 34 is attached. Each roller 30, 32, of this guide roller unit
34 is in contact with the end edge portion and side surface of the guide portion 18 of the guide rail 16. Although only the guide roller unit arranged on one side of the elevator basket 2 is shown in the figure, a guide roller unit having the same structure is also disposed on the other side of the elevator basket 2. These guide roller units, together with the main guide rails 16, guide the elevator basket 2 so that the elevator basket 2 can smoothly and stably move up and down within the elevator passage 4.

In the up-and-down passage 4, a pair of guide rails 20 and 22 for counterweight are further arranged.
