Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator cage stop lock device for stopping and locking an elevator cage.
In particular, the present invention relates to a stop lock device for an elevator cage suitable for application to an elevator without a machine room (machine roomless elevator).

[0002]

2. Description of the Related Art Conventionally, many elevators include an elevator cage (hereinafter referred to as a cage) on which a user rides, a hoist for driving the cage up and down, a counterweight as a weight balancer, and a counterbalance with the cage. It is composed of a rope that connects the weight with a hoist, and a control device that controls the operation of the entire elevator. An elevator having such a configuration is called a rope type elevator.

In a rope-type elevator having such a configuration, the space in the building where the elevator is installed requires a hoistway on which the elevator cage moves up and down, and a machine room for housing a hoist and a control device (control panel). The machine room is generally provided at the top of the hoistway.

[0004] However, in apartment houses and the like,
Due to the construction conditions such as sunshine rights, there is a case where a space large enough at the top of the building cannot be secured.

[0005] An elevator without a machine room that does not require such a space for the machine room has been conventionally proposed and realized. FIG. 8 shows an example of a conventional elevator without a machine room disclosed in Japanese Utility Model Publication No. 4-50297 (small elevator device).

In FIG. 8, a hoist is installed in a gap between a wall side reaching the top of a hoistway 41 and a projection surface of a basket 42. The hoist includes a traction sheave 45 and a driving device 43, for example, an electric motor. In addition, a pair of guide rails 47 a and 47 b having a U-shaped cross section are installed along the hoisting direction of the hoistway 41. A main frame 49 fixed to one side surface of the basket 42 and a support frame (not shown) of the counterweight 44 slide in the vertical direction by guide rails 47a and 47b.

The traction sheave 45 has a suspension rope 4
6, one end of the hanging rope 46 hangs the main frame of the basket 42, and the other end of the hanging rope 46 hangs the counterweight 44. The traction sheave 45 is driven by the driving device 43, and the driving force is transmitted to the suspension rope 46 by the friction between the suspension rope 46 and the traction sheave 45, so that the basket 42 and the counterweight 44 are raised and lowered.

[0008] Guide shoes 50 and 51 are fixed to the upper and lower portions of the main frame 49, respectively, and guide shoes 52 and 53 are fixed to the upper and lower portions of the counterweight 44, respectively.

On the other hand, a maintenance and inspection switch (not shown) is installed on the landing side. When the maintenance and inspection switch is turned on by the inspector, the basket 42 is normally moved from the lowermost position to the uppermost position. It is possible to perform an ascending and descending operation at a lower speed than the operating speed of

On the ceiling surface of the basket 42, an inspection manual operation switch is installed, and a limit switch mechanism is installed. The limit switch mechanism is disposed near the top of the hoistway, for example, as shown in FIG. 2 as a cage-side member installed on the basket 42 side, and is closed when the overwound cam contacts. The hoistway-side member for detecting a position near the uppermost portion of the hoistway includes, for example, a hoistway-side limit switch. This hoistway-side limit switch is installed near the top of the hoistway from the top floor where the basket 42 stops.

In such an inspection manual operation switch and limit switch mechanism, when the inspector operates the above-described inspection manual operation switch, the cage is operated as desired within a range until the above-described limit switch mechanism operates. It is possible to perform an inspection operation on the 42.

(1) In order to carry out maintenance and inspection of the hoisting machine, as a preliminary preparation, the inspection manual operation switch is operated to raise and lower the basket from the top floor to the hoistway ceiling side. At this time, it is necessary to release the brake to stop the basket at a predetermined position. It is also conceivable to release the brake for some reason after stopping. When the brake is released, the weight of the counterweight is greater than the weight of the cage, and since there are no or few people in the cage at the time of inspection, the cage rises in the direction of the hoistway ceiling. May be caught between the hoistway ceiling and the basket, and when the inspector works on the cage, the basket may shake, which may cause a serious accident for the inspector.

(2) Normally, in an elevator without a machine room, in order to perform maintenance and inspection of a hoist and the like, it is naturally necessary to turn off the power of the control device. However, in some cases, the power is turned off. May forget to do so, in which case the inspector may get a shock hazard.

[0015] An object of the present invention is to reduce the risk that an inspector may be pinched between a cage and a hoistway ceiling due to movement of the cage even when maintenance and inspection of a hoisting machine or the like is performed by cage work. It is an object of the present invention to provide an elevator cage stop lock device.
