DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring structure in an elevator tower and a guide rail for improving a cable laying operation in a hoistway.

[0002]

2. Description of the Related Art Conventionally, when cables are laid in a hoistway of an elevator, a wiring structure in a tower as disclosed in Japanese Patent Application Laid-Open No. 55-43959 is widely used.
In this tower wiring structure, a plurality of cable support members are attached at appropriate intervals to guide rails that are connected and erected in a hoistway, and cables are fixed to these support members. Thereby, the cable connected to the control panel in the machine room can be laid along the guide rail in the hoistway.

[0003]

However, in the above-mentioned conventional tower wiring structure, prior to the work of attaching the cables in the hoistway, first, a plurality of cable supporting members are firmly attached to the guide rails at appropriate intervals. This requires a great deal of time to attach the support member, and thus, there is a problem in that the work time involved in laying the cable is inevitably prolonged, leading to an increase in cost.

[0004] The present invention has been made in view of such circumstances, and a first object of the present invention is to provide an elevator tower wiring structure that can reduce the work time required for laying cables. A second object of the present invention is to provide a guide rail suitable for such a tower wiring structure.

[0005]

SUMMARY OF THE INVENTION A first object of the present invention is to connect a plurality of guide rails each having a groove extending in a longitudinal direction to connect the guide grooves so that the grooves are continuous. This is achieved by storing the cable in the housing.

A second object of the present invention is to provide a guide rail with a groove extending in a longitudinal direction for accommodating a cable, and a stopper mounted across the groove for positioning the cable. This is achieved by providing

[0007]

[Function] If the cable is directly attached to the guide rail by using the groove of the guide rail, it is not necessary to separately attach a cable supporting member which has been conventionally used, so that the work time required for laying the cable is greatly reduced. Can be shortened.

[0008]

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

FIGS. 1 to 3 show an embodiment of the present invention. FIG. 1 is an overall structural view, FIG. 2 is a sectional view of a main part, and FIG. 3 is a perspective view of a guide rail connecting portion.

In these figures, reference numeral 1 denotes a hoistway of an elevator surrounded by a concrete wall, 2 denotes a plurality of guide rails connected to each other and stands upright in the hoistway 1, and 3 denotes a guide rail 2 connected to the hoistway 1. A rail bracket for fixing to a wall surface of each of the guide rails. A concave groove 2a extending in a longitudinal direction is formed at a central portion of each guide rail 2, and each guide rail is formed so that these concave grooves 2a become a continuous vertical groove. The rails 2 are connected. Reference numeral 4 denotes a counterweight which is guided by the guide rail 2 to move up and down in the hoistway 1. Reference numeral 5 denotes a machine room installed on the upper portion of the hoistway 1. Reference numeral 6 denotes a control panel installed in the machine room 5. A cable connected to the control panel 6 and laid along the guide rails 2 in the hoistway 1, 8 is an indicator box installed on the hall side of each floor, and 9 is a synthetic resin fitted to the guide rail 2. Stopper, cable 7
The cable 7 is housed so as to be fitted into the concave groove 2a of the guide rail 2, and by attaching the stopper 9 across the concave groove 2a, the cable 7 is positioned in the concave groove 2a. Reference numeral 10 denotes a connecting member for connecting the adjacent guide rails 2, and reference numeral 11 denotes a bolt for fixing the connecting member 10 to the guide rail 2.

When the guide rails 2 are erected in the hoistway 1, the guide rails 2 are lifted from above and connected sequentially. At this time, as shown in FIG. The cable 7 is fitted into the concave groove 2a, and the stopper 9 is located at a position across the concave groove 2a of the guide rail 2.
And the operation of positioning the cable 7 is performed in parallel. However, since the cable 7 is positioned by the connecting member 10 at the portion where the guide rails 2 are connected as shown in FIG. 3, the stopper 9 is unnecessary. By repeating the operation of connecting the guide rails 2 and the operation of attaching the cables 7, the laying of the cables 7 is completed when the guide rails 2 have been erected in the hoistway 1.

That is, conventionally, a cable supporting member had to be attached to the guide rail prior to the cable attaching operation, and the attaching operation of this supporting member required a great amount of time. Since the cable 7 can be directly attached to the guide rail 2 by using the groove 2a, the cable supporting member conventionally used is not required, and as a result, the work time required for laying the cable 7 is greatly reduced. And the total cost can be reduced. In addition, when the vehicle is operated on a car for maintenance and inspection of an elevator, the risk is great because the cable support member protrudes from the guide rail in the past. Since it is only added, it does not become a hazardous material and has the advantage that the operation on the car can be performed safely.

A groove 2a provided in the guide rail 2
It is only necessary to have a space in which the cable 7 can be stored. If a cable having a different shape or number from the above embodiment is used, the shape of the concave groove may be appropriately changed accordingly. Further, in the above embodiment, the stopper 9 made of synthetic resin, which is easily attached to the guide rail 2 by utilizing the flexibility, is used. Can be appropriately selected as long as it does not hinder the operation of the elevator.

FIG. 4 is a perspective view of a main part showing another embodiment of the present invention. In this embodiment, the groove 2a of each guide rail 2 is used.
The cable 7 and the connector 12 to which the end of the cable 7 is connected and fixed are stored in advance, and if the guide rails 2 are connected while connecting the pair of connectors 12, The cable 7 can be automatically laid.

[0015]

As described above, according to the present invention, since the cable is accommodated in the concave groove of the guide rail, a cable supporting member which requires a lot of time for mounting work is not required. The work time required for laying can be greatly reduced, and the cost can be reduced accordingly.
