[0003]
In the figure, 1 is an elevator car, 2 is a counterweight, and 3 is a main rope. One end of the main rope 3 is fixed to the upper part of the hoistway 17, and the hoistway 17 is passed through pulleys 5 and 4 of the car 1. The other end is fixed to the upper part of the hoistway 17 via the pulley 12 on the upper part, the traction sheave 7, the pulley 12 on the upper part of the hoistway 17, and the pulley 13 of the counterweight 2. Reference numeral 9 denotes a cabinet-type machine space fixed to the lower wall 15 of the hoistway 17, and the drive device 6 and the control panel 8 are fixed to the frame 20. Reference numeral 14 denotes a wall of the machine space 9. 10 is a guide rail of the car 1, 11 is a guide rail of the counterweight 2, 18 is a landing side opening, and 19 is a car side opening.
[0004]
FIG. 7 shows an example in which the machine space 109 is arranged above the hoistway 17, and a part of the machine space 109 extends into the wall 15 of the hoistway 17 as a notch 110. Reference numeral 114 denotes a wall of the machine space 109, and 116 denotes a door provided on the landing side of the notch 110. The same reference numerals as those in FIG.

[Problems to be solved by the invention]
4 to 6, the control panel 8 is arranged beside the driving device 6, that is, the control panel 8 and the driving device 6 have different spaces on the cross section of the hoistway 17 shown in FIG. 5. Since it is occupied, there is a problem that it becomes an obstacle to space saving of the hoistway 17, and there is a problem that when the door of the control panel 8 is opened in maintenance inspection, the door becomes an obstacle.
7 has a problem that the notch 110 must be provided in the hoistway wall 15 in addition to the problem in FIG.
[0007]
[Means for Solving the Problems]
The present invention relates to an elevator having a sheave on which a main rope and the like connecting the car and the counter weight are wound, and between the side where the main rope and the like enter and exit the sheave In addition, a control panel having a double door that is a folding door that opens from the middle to the outside of each door is located, and when the folding door is opened to the outside in a cross section, each folding door is The car overlaps with the sheave and the car is positioned so as not to overlap .
In the cross section, the control panel overlaps with the sheave, and when the folding door is opened to the outside, the folding doors are positioned so that the car does not overlap.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. 1 is a view corresponding to FIG. 6, and FIG. 2 is a cross-sectional view of FIG. In the figure, reference numeral 20 denotes a control panel, which is provided between the side of the main rope 3 that enters the traction sheave 7 and the side that exits the traction sheave 7 in the projection plane in the rotational axis direction of the traction sheave 7 (that is, FIG. 1). ing. Reference numeral 21 denotes a door of the control panel 20, which is a double door.
[0009]
In the present embodiment, the control panel 20 and the drive device 6 overlap each other in the cross section of the hoistway 17, that is, the space above the drive device 6 is effectively used, so that the space of the hoistway 17 can be saved. . Moreover, when carrying out the maintenance inspection of the control panel 20 on the car 1 or from the pit, the opened door 21 serves as a rope guard for the main rope 3, so that safety is high.
[0010]
FIG. 3 shows another embodiment of the present invention in which the door 22 is a folding door that opens from the middle to the outside. With this configuration, the car 1 can be jogged with the door 22 open, so that the maintenance inspection efficiency is improved.
[0011]
Although not shown in FIGS. 2 and 3, the doors 21 and 22 are fixed by stoppers during maintenance and inspection in order to keep the doors 21 and 22 open. Further, in each of the embodiments described above, the drive device 6 and the like are installed at the lower part of the hoistway 17, but even when installed at the upper part of the hoistway 17, the top and bottom of FIG. In the same manner, it can be implemented.
Further, the sheave in which the control panel 20 is arranged in the vicinity is not limited to the traction sheave 7, and an appropriate sheave is selected even if the elevator directly drives the main rope 3 without using the traction sheave. 20 can be arranged. The same applies to an elevator using not only the main rope 3 but also other members such as a belt (collectively referred to as main rope).
[0012]
【The invention's effect】
As described above, according to the present invention, the space for the hoistway can be saved, and the efficiency of maintenance and inspection can be improved and the safety can be improved.
