Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, in the case of laying a cable in a hoistway of an elevator, a wiring structure inside a tower as disclosed in Japanese Patent Laid-Open No. 55-43959 is widely used.
This in-tower wiring structure is to attach a plurality of cable supporting members at appropriate intervals to a guide rail connected to each other and standing upright in the hoistway, and to fix the cables to these supporting 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-described conventional in-tower wiring structure, prior to the work of attaching the cables in the hoistway, first, the plurality of cable supporting members are firmly secured with proper intervals on the guide rails. Since the supporting member must be mounted on the cable, and the mounting work of the supporting member requires a lot of time, there is a problem that the working time required for laying the cable is inevitably lengthened and the cost is increased.

The present invention has been made in view of the above circumstances. A first object of the present invention is to provide an elevator tower wiring structure capable of shortening the work time required for laying cables. A second object of the present invention is to provide a guide rail suitable for such a wiring structure in a tower.

[0005]

The first object of the present invention described above is to connect a plurality of guide rails having a groove extending in the longitudinal direction to make the groove continuous so that the inside of the groove is continuous. This is accomplished by housing the cable in.

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

[0007]

[Operation] 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 the cable supporting member which has been conventionally used, so that the work time required for laying the cable is significantly increased. 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 an essential part, and FIG. 3 is a perspective view of a guide rail connecting portion.

In these drawings, reference numeral 1 is an elevator hoistway surrounded by concrete wall surfaces, 2 is a guide rail which is connected to a plurality of guide rails and stands upright in the hoistway 1, and 3 is a guide rail 2 which is a hoistway 1. A rail bracket for fixing to the wall surface of each guide rail. A groove 2a extending in the longitudinal direction is formed in the center of each guide rail 2, and each groove is formed so that each groove is a continuous vertical groove. The rail 2 is connected. Further, reference numeral 4 is a counterweight guided by the guide rails 2 to move up and down in the hoistway 1, 5 is a machine room installed above the hoistway 1, 6 is a control panel installed in the machine room 5, and 7 is a control panel. 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 rails 2. Stop the cable 7
Is stored by being fitted into the groove 2a of the guide rail 2, and the cable 9 is positioned in the groove 2a by mounting the stopper 9 across the groove 2a. Further, reference numeral 10 is a connecting member for connecting adjacent guide rails 2, and 11 is a bolt for fixing the connecting member 10 to the guide rail 2.

When the guide rail 2 is erected in the hoistway 1, the guide rail 2 is hoisted from above and connected sequentially. At this time, as shown in FIG. The cable 7 is fitted in the groove 2a, and the stopper 9 is placed at a position across the groove 2a of the guide rail 2.
Is attached and the cable 7 is positioned in parallel. However, since the cable 7 is positioned by the connecting member 10 at the portion where the guide rails 2 are connected to each other as shown in FIG. 3, the stopper 9 is unnecessary. By repeating the work of connecting the guide rails 2 and the work of attaching the cables 7, the laying of the cables 7 is completed when the guide rails 2 have been installed upright in the hoistway 1.

That is, conventionally, the cable supporting member had to be attached to the guide rail prior to the cable attaching work, and it took a lot of time to attach the supporting member. Since the cable 7 can be directly attached to the guide rail 2 using the groove 2a, the conventionally used cable supporting member is unnecessary, and as a result, the work time required for laying the cable 7 is significantly reduced. However, the total cost can be reduced. Moreover, when the car is operated for maintenance or inspection of the elevator, the cable supporting member has been protruding from the guide rail, which is dangerous, but in the above embodiment, the stopper 9 is in close contact with the guide rail 2. Since it is only added, it does not become a hazardous material, and it has the advantage that it can be safely carried out on the car.

A concave groove 2a provided in the guide rail 2
Since it suffices to have a space in which the cable 7 can be stored, when a cable having a different shape or number from the above-mentioned embodiment is used, the shape of the concave groove may be appropriately changed accordingly. Further, in the above-mentioned embodiment, the stopper 9 made of synthetic resin which is easily attached to the guide rail 2 by utilizing its flexibility is used. It can be appropriately selected as long as it can be performed without any trouble in the operation of the elevator.

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

[0015]

As described above, according to the present invention, by storing the cable in the groove of the guide rail, the cable supporting member, which requires a lot of time for the mounting work, is unnecessary. The work time required for laying can be significantly reduced, and the cost can be reduced accordingly.
