Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to an elevator tower wiring system, and more particularly to an elevator tower wiring system that can be used to construct wiring for a plurality of electrical devices installed inside and outside of a hoistway. It is related to.

0002

[Prior Art] Conventionally, wiring for various electrical devices installed inside and outside of elevator towers has been carried out by attaching a plurality of brackets to guide rails erected on the walls of the hoistway. Alternatively, metal fittings are attached to the inner wall or steel frame of the hoistway and fixed to the metal fittings. As a conventional in-tower wiring system for this type of elevator, there is a technique disclosed in Japanese Patent Application Laid-Open No. 52-59439.

However, the conventional elevator tower wiring is
Each building has a different structure, such as reinforced steel or concrete, and a wide variety of brackets and metal fittings are required, and they are also used in large quantities. Furthermore, as buildings become taller, the number of brackets, metal fittings, etc. increases, which requires a large amount of material cost. Furthermore, the brackets, metal fittings, etc. are brought in as single items and must be attached one by one by welding or the like in the hoistway, where working conditions are not good, resulting in poor workability.

[0004] Therefore, as an in-tower wiring system for an elevator, which allows wiring to be easily installed regardless of the length or structure of the hoistway, the one disclosed in Japanese Patent Laid-Open No. 2-55355 has been considered. This publication discloses a technique in which a cable-like body such as a wire is stretched in the longitudinal direction of a hoistway and wiring is attached to the cable-like body.

[0005]

[Problems to be Solved by the Invention] However, in the conventional elevator tower wiring system described in the above-mentioned publication, the wiring can become displaced from the cord-like body such as wire stretched in the longitudinal direction of the hoistway during work. It was necessary to attach wiring to prevent it from falling. Especially if the machine room is located below the hoistway.
A special device was required to support the load of the wiring at the top of the hoistway, and the wiring had to be constructed with due consideration to the load of the wiring cables. This will be explained using a diagram.

FIG. 6 is a perspective view showing the main parts of a conventional elevator tower wiring system, showing the vicinity of the top in the hoistway.

In the figure, 2 is a branch box for branching the wiring;
4 is a wiring cable; 9 is a wire stretched in the longitudinal direction of the hoistway; 11 is a wire bracket; 14 is a branch box mounting bracket that supports the branch box 2; 15 is a guide rail that guides the elevator car up and down; 16 is the wiring cable 4
This is the binding line that connects the .

When the machine room (not shown) is located below, the wire bracket 11 is attached to the guide rail 15 located further above the branch box 2 located at the top, as shown in FIG.
It was necessary to attach the wiring cable 4 by attaching it and applying the load of the wiring cable 4 to the wire bracket 11. Further, it is necessary to carry out the attachment work in such a way that the wiring cable 4 does not slip off from the electric wire or wire 9 suspended from the wire bracket 11.

Therefore, the present invention provides an elevator in which the load of the distribution cable 4 is carried by a cord-like body such as a wire stretched in the longitudinal direction of the hoistway, and the distribution cable 4 can be easily fixed in the branch box. The objective is to provide an in-tower wiring system.

[Means for Solving the Problems] An in-tower wiring device for an elevator according to the present invention has a cable-shaped body stretched in the vertical direction in the hoistway, wirings arranged in parallel approximately along the cable-shaped body, and ,
The wiring is fixed to the cable body near the top in the hoistway using a fixing means.

[0011]

[Operation] In the elevator tower wiring system of the present invention, the wiring is arranged in parallel approximately along the cable-shaped body stretched in the vertical direction in the hoistway, and the wiring is connected near the top of the hoistway. Since it is fixed to the cable-shaped body, the load of the wiring can be carried by the cable-shaped body, and the wiring does not slip off during work such as fixing the wiring in the branch box.

A tightening screw 24 is used to fix the wiring cable 4 by tightening it.

In order to fix the wiring cable 4 to the wire 9 using the fixing means 20, first, the wire clip 21 is
The wire 9 is inserted into the approximately U-shaped curved portion 21a and tightened with the tightening screw 23. A plurality of substantially wedge-shaped uneven portions 21b are formed on the contact surface of the curved portion 21a with the wire 9, so that the wire 9 can be tightened with the tightening screw 23.
is firmly fixed to the curved portion 21a. Furthermore, a notch 21d that can be engaged with the insertion section 22a of the cable holding member 22 is formed by punching in the cable pressure contact surface 21c of the wire clip 21. Therefore, the wire clip 21 and the cable holding member 22 are assembled together by inserting the insertion portion 22a into the notch 21d while the wiring cable 4 is sandwiched between the cable holding member 22 having a substantially U-shape. .

They are sequentially fixed to the branch box 2 and tied to the wires 9 using binding wires 16 as appropriate and arranged in parallel. In FIG. 1, the distribution cable 4 is fixed to the wire 9 near the bottom of the branch box 2 located at the top. In this way, by fixing the distribution cable 4 to the wire 9, the load of the distribution cable 4 is supported by the wire 9, so the load of the distribution cable 4 applied to the branch box 2 can be reduced, and the wiring in the branch box is fixed. Not only can the work be done easily, but also the wiring cable 4 can be removed during installation of the wiring cable 4.
will not fall off the wire 9. Additionally, there is no need for the various brackets and metal fittings required for conventional elevator tower wiring work, so material costs can be reduced. Furthermore, simply by fixing the wiring cable 4 to the wire 9 using the fixing means 20, the work of attaching the wiring cable 4 can be carried out step by step, resulting in good work efficiency and a reduction in the number of man-hours by approximately 2 compared to the conventional construction method.
It can be reduced by about 0%.
