Description

[Detailed Description of the Invention] This invention relates to an improvement of an elevator installation member.

First, a conventional installation member will be explained with reference to FIGS. 1 to 3.

In the figure, 1 is the elevator hoistway, 2 is the opening consisting of the lift port provided at the top of the hoistway, 3 is the floor of the machine room located above the hoistway 1, and 4 is the opening provided on the hoistway. opening 2
5 is an anchor bolt that is placed upright at the edge of each of the four corners of the opening 2 and inserted through the plate 4, 6 is a nut screwed into this, and 7 is a bolt on the landing side. 8 is an installation part consisting of a hole for centering the equipment centering; 8 is an installation part consisting of a hole for centering the guide rail on the car side; 9 is an installation part consisting of a hole for centering the guide rail on the weight side; 10 is an installation part 7 to 9.
It is held on the plate 4 by a plumb bob that is placed at a predetermined position and inserted through the plumb bob.

11 is an insertion hole for an elevator main cable (not shown).

That is, after equipment (not shown) installed in the machine room is carried in from the hoistway 1 through the opening 2, the opening 2 is closed by the plate 4.

At the same time, by fixing the plate 4 at a predetermined position, the center position necessary for installing the elevator can be obtained via the installation parts 7 to 9 provided on the plate 4.

A machine stand (not shown) is installed on top of the plate 4, and a lifting machine (not shown) is installed on this, and the main rope wound around this is inserted into the insertion hole 11 to enter the hoistway It is designed to be suspended in the

However, since it is necessary to give the plate body 4 a rigidity corresponding to the dimensions of the opening 2, the plate body 4 becomes abnormally thick and heavy, making it inconvenient to handle. This resulted in problems such as an increase in both weight and manufacturing costs.

This invention aims to provide an elevator installation member that has high rigidity and can be manufactured at low cost.

An embodiment of this invention will be described below with reference to FIG.

In the figure, the same reference numerals as those in Figures 1 to 3 indicate corresponding parts, and 4 indicates two plates 4a and 4b, each of which is bent on one side, from a bolt inserted through the bent part and a nut screwed into the bent part. 13 is an insertion hole for a speed governor rope (not shown) provided in the plate 4, and 14 is a car side rail (not shown) provided in the plate 4.
insertion hole of a lifting device (not shown) for lifting the
16 is an insertion hole for a lifting device (not shown) provided in the plate body 4 to lift the weight side rail (not shown); 16 is an insertion hole for an electric wire (not shown) to be wired from the machine room into the hoistway 1; 17 is a box-shaped duct with an open bottom surface.
The open surface side is fixed to the plate 4 by welding or the like, and the insertion opening 16 is arranged as a cover.

Reference numeral 18 denotes a lid removably provided in the wire hole located near the upper end of the duct 17; 19 a lid removably provided in the wire hole located on the longitudinal end surface of the duct 17; A straight box connector (not shown) for wiring is attached to the knockout hole provided on the side of the connector.

21 is a reinforcing member made of angle iron fixed to the plate 4b.

That is, the plate body 4 is fixed at a predetermined position and centered through the installation parts 7 to 9, and the rail is lifted up through the insertion holes 14 and 15 to be erected in the hoistway 1.

Further, a rope is suspended through the insertion hole 11.13.

Next, the electric wires are highly purified through the duct 17 to equipment in the machine room and equipment in the hoistway.

The duct 17 increases the rigidity of the plate 4, and the rigidity can be increased without increasing the thickness of the plate 4 itself, resulting in a lightweight and inexpensive plate 4.

Further, since the duct 17 can be easily attached to the plate body 4 at the factory, complicated steps at the installation site can be omitted and installation costs can be reduced.

In this embodiment, the plate body 4 is made up of the plates 4at4b, so if these are separated, transportation becomes easy, and the plate body 4 can be easily carried into the machine room through the opening 2.

Further, the bent joint portion of the plate 4 at 4 b also contributes to improving the rigidity of the plate body 4 .

As explained above, this invention has a plumb bob installation part, a rope insertion hole, and a wiring duct provided in the plate that covers the lifting opening of the hoistway. Since the rigidity of the elevator is improved, a plate with high rigidity can be obtained at low cost using a small amount of materials, thereby realizing an elevator installation member that can reduce manufacturing and installation costs of the elevator.
