Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an improvement of a control cable device for a diagonal elevator used as a means of transportation to a building built in a stair-like manner on a mountain slope or the like.

[Prior art]

Conventionally, as a control cable device for a diagonal elevator, one disclosed in Japanese Utility Model Application Publication No. 135563/1983 is known. Such a conventional control cable device for a skew elevator will be explained with reference to FIGS. 1 to 3. In these figures, 1 and 2 are a car and a counterweight that run on rails (not shown) installed along the longitudinal slope of the hoistway, and 3 is a hoist installed above the hoistway. Machine, 4
is a main rope whose one end is connected to the car 1 and the other end is connected to the counterweight 2, 5 is a deflection wheel for the main rope 4, and the car 1 is tilted up and down by the drive of the hoist 3. It is designed to move back and forth within the road. 6 is a control cable that supplies power to car 1, 7
1 is a carrier on which a control cable 6 is suspended, and is composed of a top carrier 7a, a plurality of intermediate carriers 7b, and an end carrier 7c. 8 has one end connected to the top carrier 7a,
Driving ropes each having its other end connected to the counterweight 2; reference numeral 9 denotes a messenger wire rope connected between the intermediate carriers 7b, between the intermediate carrier 7b and the top carrier 7a, and between the intermediate carrier 7b and the end carrier 7c; 10; is a drive rope deflector mounted on the hoistway wall;
Reference numeral 11 denotes a guide rail installed along the longitudinal direction of the hoistway, and the guide rail 11 is
It supports and guides the top and intermediate carriers 7a and 7b, and is placed at a height that the worker can reach from above the car 1. An end carrier 7c is fixed to the lower end of the guide rail 11. has been done.

In the conventional skew elevator control cable device configured as described above, when the car 1 rises from the lowest floor stopping position to the highest floor stopping position, the top carrier is moved by the driving rope 8 and messenger wire rope 9. 7a and intermediate carrier 7b
are pulled up one after another, and the control cable 6 is extended into a nearly straight line. Further, when the car 1 descends from the top floor, the top and intermediate carriers 7a and 7b are sequentially stored in the lower part of the hoistway, and the control cable 6 is contracted into a loop shape.

In such a conventional control cable system for a diagonal elevator, when performing maintenance inspections on the top carrier 7a and intermediate carrier 7b, a ladder or stepladder with a height that reaches the bottom of the hoistway to reach the carriers is brought in and the ladder or stepladder is brought in to reach the bottom of the hoistway. Since a worker climbs on top of the machine to carry out maintenance and inspection work, there were problems in that workability was poor and work could not be done safely.

[Summary of the idea]

This idea is an attempt to solve the above-mentioned problem with the conventional one. By locking the carrier with a stopper installed in the hoistway, a worker can ride on the car and perform maintenance and inspection of the carrier. The object of the present invention is to provide a control cable device for a diagonal elevator that allows these operations to be performed easily, efficiently, and safely.

[Example of idea]

An embodiment of this invention will be described below with reference to FIGS. 4 to 6. In these figures, figures 1 to 3
The same symbols as in the previous figures indicate the same or equivalent parts.
12 is a stopper installed in the hoistway. The stopper 12 is a case 12a fixed to the hoistway wall.
A stopper metal 12b is pivotally attached to the case 12a so that it can be stored in the case 12a, and the stopper metal 12b is connected to the upper end of the operating rod 12d via a link 12c, and the operating rod 12d extends downward. 12e fixed to the hoistway wall. Note that the configuration of this embodiment other than those described above is the same as that shown in FIGS. 1 to 3.

In the control cable device of the embodiment configured as described above, the car 1 is raised to the top floor with the stopper metal 12b of the stopper 12 housed in the case 12a, and the operating rod 12d is pushed up to release the stopper metal 12b. It protrudes downward near the guide rail 11. When the car 1 is lowered in this state, the intermediate carrier 7b and the top carrier 7a are sequentially locked to the stopper metal 12b, and when the car 1 is lowered to near the bottom floor, the control cable 6 is connected to the rear side of the car 1. is located. In this state, when a worker gets on the car 1, the worker can reach the top carrier 7a and the intermediate carrier 7b from above the car 1. Therefore, the worker can access the top carrier 7a and the intermediate carrier 7 from the top of the car 1 without getting on a ladder or the like.
(b) can be easily and safely maintained and inspected with good workability. In addition, in this example,
By locking the operating rod 12d of the stopper 12 to the presser foot 12e at its lower end,
The top carrier 7a,
The locking of the intermediate carrier 7b by the stopper metal 12b may come off during maintenance and inspection work, or the top carrier 7a and the intermediate carrier 7b may be locked by the protrusion of the stopper metal 12b when the locking is not necessary. do not have.

[Effect of idea]

As explained above, the control cable device for a skew elevator according to this invention has a stopper installed in the lifting section and the carriers are locked by this stopper, so that the carriers are stopped one after another and the carriers and control cables are stopped. Since it can be positioned on the back side of the car, it has the effect that operators can easily and safely perform maintenance and inspection of the carrier from above the car.
