Abstract

PURPOSE:To improve the safety by providing guides in the upper part of a car moved to be guided through guide rollers on an inclined guide rail, and providing a guide rail engaged with these guides in a lift well, so as to reduce the vibration of car at the time of earthquake or the like. CONSTITUTION:In an inclined elevator, guide rollers 3 provided in the lower part of a car 1 are rollably mounted on a lower part guide rail 5 laid in a tilted lift well 15, to lift this car 1 in a well bucket manner through a rope connected to a movable balance weight through guide rollers 8 along a balance weight guide rail 9. Here is provided upper part guides 4 serving as the guides in an upper part of the car 1, to arrange an upper part guide rail 6, engaged with this guide, parallelly to the lower part guide rail 5. In this way, the vibration of car is reduced at the time of earthquake or the like, and also preventing the car from its tumble to improve the safety.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oblique elevator,
In particular, it relates to a guide rail for an oblique elevator with improved safety.

[0002]

2. Description of the Related Art The structure of a conventional guide rail of an oblique elevator is as described in JP-A-58-14817. In other words, the guide rollers guide the car that moves up and down along the two guide rails laid under the inclined hoistway. There is a risk of hitting
There was a risk that the car could fall when the emergency stop device was activated for some reason while the car was traveling to the valley side.

[0003]

Since the conventional oblique traveling elevator has a structure in which two guide rails for guiding the car are provided in the lower part of the car, the car is in an earthquake or the emergency stop device operates. In addition, there is a problem that the car may collide with the landing door and the car may collide with the hoistway wall, and a member having a high strength is required as a member constituting the car.

An object of the present invention is to provide a car with high safety in a diagonal elevator.

[0005]

The above object can be achieved by providing a guide rail in the upper part of the hoistway of the oblique elevator and a guide device in the upper part of the car.

[0006]

[Function] Although two guide rails for guiding the conventional elevator car are provided at the lower part of the car, the provision of the guide rails at the upper part of the car also activated the emergency stop device during an earthquake. Even at times, the car does not vibrate, the car door does not collide with the landing door, and the car does not collide with the hoistway wall, which can increase safety, and the members constituting the car have a relatively small strength. It becomes possible to use a member that has.

[0007]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a vertical sectional view of a hoistway of an oblique elevator,
FIG. 2 is a cross-sectional view of the hoistway.

A car lower guide rail 5 and a counterweight guide rail 9 are laid by a lower guide rail fixing bracket 10 and a rail clip 12, and a car upper guide rail 6 is attached to an upper guide rail fixing bracket 11 and a rail. In the hoistway 15 laid by the clip 12, the car 1 configured by the car component member 2 is driven by the car lower guide roller 3 and the car upper guide device 4 to lower the car lower guide rail 5 and the car. Raises and lowers via the car upper guide rail 6, and the counterweight 7
The counterweight guide roller 8 moves up and down through the counterweight guide rail 9.

Since the car 1 is guided up and down,
Vibration of the car due to an earthquake, etc.
When the car 1 hits the hoistway wall, it can be safely lifted and stopped without damage, and even when the emergency stop device operates for some reason while traveling to the valley side, the car 1 Since the upper part of the car is guided, the car can be stopped safely without falling.

[0011]

According to the present invention, by laying the guide rail on the upper part of the car, the vibration of the car at the time of an earthquake or the like can be reduced, so that the safety can be improved.
Further, it becomes possible to use a member having a relatively smaller strength than the conventional one as a member constituting the car.
