Description

[Detailed Description of the Invention] This invention relates to an oblique bending elevator installed in a steel tower or the like having a bend, that is, an elevator in which an elevator car reciprocates in a hoistway in which the angle of inclination on both sides of the bend changes.

In an elevator in which the elevator car reciprocates in a hoistway whose inclination angle changes as described above, it is required that the floor of the elevator car compartment be kept always horizontal regardless of changes in the inclination angle of the hoistway.

In response to the above-mentioned requirements, this invention provides a diagonal bending elevator that controls the attitude of the elevator car to keep the floor of the car room horizontal at all times even if there is a bend in the hoistway, allowing for stable running. It is intended to.

An example of this invention is shown below in Figures 1 to 3.
The diagram will be explained.

In FIGS. 1 to 3, 1 is a bent portion 1a.
2 is an elevator car that ascends and descends within the hoistway 1; A main rail 3 is disposed on the ceiling of the slanted hoistway 1 over the entire length along the longitudinal direction of the hoistway 1, and furthermore, on the bottom side of the slanted hoistway 1, the floor of the elevator car 2 is always kept level. A posture control rail 4 for holding the main rail 3 along the entire length of the hoistway.
At the bottom of the hoistway 1, a counterweight rail 5 is further arranged. bending part 3 respectively
a, 4a, and 5a are formed, and the angle of inclination of the upper and lower portions with respect to the horizontal plane changes with these bent portions as boundaries. Further, the rails 3, 4, and 5 are each fixed to a support frame 7 via a rail bracket 6, and extend along the longitudinal direction of the hoistway 1.
A drive frame 8 is supported on the main rail 3 so as to be freely movable. That is, a pair of left and right upper and lower guide rollers 9 and 1 are pivotally mounted at multiple locations in the front and rear of the drive frame 8.
0, the main rail 3 is clamped. Above drive frame 8
The upper part of the elevator car 2 is connected to the pivot 1 at the bottom of the
The elevator car 2 is connected to the elevator car 1 so as to be rotatable in the up-and-down direction of the car, and a car chamber 12 is formed in the elevator car 2.
The lower part of the elevator car 2 is supported by an attitude control rail 4 so as to be freely movable. That is, the lower part of the elevator car 2 is attached to a support plate 13 fixed to the upper end of the hoistway 1, and a pair of left and right upper and lower guide rollers 1
4, 15 are pivotally mounted, and these rollers 14, 15
At the same time, the attitude control rail 4 is held between the
Upper and lower guide rollers 17 and 18 are pivotally attached to the distal end of the mounting plate 16, which is rotatably supported by the support plate 13 and extends obliquely downward from the pivot point.
The attitude control rail 4 is also held between these rollers 17 and 18. An antenna 19 is mounted on the mounting plate 16 for transmitting and receiving various signals for controlling the operation of the elevator. One end of a plurality of main ropes 20 is connected to the drive frame 8, and the main ropes 20 are wound around a drum 21 of a hoist in a machine room 28 provided above the hoistway 1. The other end of 20 is a counterweight 22
The counterweight 22 is movably supported by the counterweight rail 5. That is, the counterweight rail 5 is held between a pair of left and right upper and lower guide rollers 23 and 24, which are pivotally attached to both the front and rear ends of the counterweight 22. In addition, in FIG. 1, 25 and 26 are the main rail 3 and the bent portion 3 of the counterweight rail 5.
This is a main rope guide roller disposed at a portion facing the rollers 25 and 5a, and by supporting the main rope 20 with these rollers 25 and 26, the main rope 20
This prevents the main rope 3 from interfering with each rail and the hoistway 1. Further, 27 in FIG. 2 is an emergency stop device provided on the drive frame 8.

The oblique bending elevator configured as described above drives the hoist and rotates the drum 21 in the forward and reverse directions, thereby moving the drive frame 8 using the main rope 20.
The elevator car 2 moves up and down within the hoistway 1 along the main rail 3 and the attitude control rail 4. In this case, even if the elevator car 2 passes through the bent portions 3a and 4a of the main rail 3 and the attitude control rail 4, and the inclination angles of the rails 3 and 4 change on both sides of the bent portions 3a and 4a, the main rail 3 An elevator car 2 is pivotally mounted to a drive frame 8 that is supported so as to be freely movable in a vertical direction.
Attitude control rail 4 whose lower part is parallel to the main rail 3
Since the drive frame 8 and the elevator car 2 are engaged in a movable manner, the relative angle between the drive frame 8 and the elevator car 2 is changed, and the floor surface 12a of the car chamber 12 provided in the car 2 is always maintained in a horizontal state, so that the elevator 2 can move freely. It will be running. Furthermore, since the elevator car 2 is vertically supported with the upper part supported by the main rail 3 via the drive frame 8 and the lower part supported by the attitude control rail 4, the relative relationship between the drive frame 8 and the elevator car 2 is There is little shaking even when the angle changes, allowing for stable driving.

In addition, in the above embodiment, an oblique bending elevator in which the bending part is located at one place in the hoistway was explained.
This idea can also be applied to structures that have multiple bends and the angle of inclination changes on both sides of the bend.

As explained above, in the oblique bending elevator of this invention, the drive frame 8 is movably supported by the main rail 3 whose inclination angle changes on both sides of the bend part 3a, and the main rope 20 is connected to the drive frame 8. , the upper part of the elevator car 2 is pivotally attached to the lower part of the drive frame 8 so as to be rotatable in the vertical direction, and the lower part of the elevator car 2 can freely run on the attitude control rail 4 whose inclination angle on both sides of the bent part 4a changes. Since it was supported, main rail 3,
Even if the angle of inclination with respect to the horizontal plane changes on both sides of the bent portions 3a, 4a of the attitude control rail 4,
Floor surface 12 of the car room 12 provided in the elevator car 2
It is possible to run the elevator car 2 while always keeping the car horizontally, and the bending parts 3a, 4
There is an effect that the elevator car 2 can run stably without shaking even when passing through point a.
