Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the installation of an elevator having a hoist provided at the upper part of a hoistway, a car and a hanging weight which are hung in a slant manner by a hoisting rope wound around the hoist. More particularly, the present invention relates to a method for installing a relatively small-sized elevator such as a home elevator for a private house.

[0002]

2. Description of the Related Art Conventionally, as a method of installing a small elevator such as a home elevator for a private house, for example, Japanese Patent Publication No. 7-5
As described in Japanese Patent No. 5777, a hoisting wheel of a slinging rope is attached to the lifting beam installed at the top of the hoistway from the landing on the top floor, and the hoisting wheel is mounted on the hoistway at the bottom of the hoistway. The two guide rails on the right and left sides are hung up simultaneously with a winch rope, lifted up and set up on the hoistway, and a number of vertically continuous holes are opened vertically behind the guide rails near the landing on the top floor. 2. Description of the Related Art An elevator installation method has been proposed in which various operations such as setting of a piano wire for guide rail centering and centering and fixing of a guide rail are performed using an elongated hole.

Further, as shown in, for example, Japanese Patent Application Laid-Open No. 10-36032, a temporary hoist such as a winch installed at the top of a hoistway suspends a car frame, which is a main product, to a hoist. There is also proposed a method in which the car frame is moved up and down by driving the car to perform an elevator installation operation on the car frame.

[0004]

According to the above-mentioned conventional elevator installation method, a temporary elevator installation work floor device is assembled on the back of the guide rail after standing to perform various operations of elevator installation. In what to do, in order to install all elevator equipment in the hoistway, it is necessary to change the installation position of the work floor device, every time,
There is a problem in that assembly and disassembly must be performed, and work efficiency is poor. In addition, this can be solved by using a plurality of work floor devices. However, since the work floor device is a temporary product and requires equipment costs, there is a problem in work efficiency and economy in any case.

[0005] In addition, in the case where a temporary lifting machine installed on the top of a hoistway performs elevator installation work while raising and lowering a car frame as a main product, equipment in the hoistway arranged above the hoistway is used. Is not accessible from above the car frame, and it is necessary to install a temporary product similar to the work floor device described above near the landing on the top floor.

The present invention has been made in view of such a situation in the prior art, and a main object of the present invention is to install equipment in a hoistway over the entire travel of a hoistway without requiring a temporary work floor device. An object of the present invention is to provide an elevator installation method that can be attached.

Another object of the present invention is to provide a method of installing an elevator which can efficiently perform a lifting operation of a lifting rope when installing the elevator.

[0008]

In order to achieve the above main object, a first aspect of the present invention is a hoist installed on an upper portion of a hoistway, and a hoist wound around the hoist. A hanging weight fixed to one end of a rope, a riding car fixed to the other end of the hoisting rope and having a car room formed from a car frame and a side plate, and a plurality of cars that are sequentially erected on the hoistway. A guide rail for guiding the car, comprising a guide rail member of a book, and an elevator in which the hanging weight and the car are lifted up and down in the hoistway in accordance with the drive of the hoist. In the installation method, the plurality of guide rail members are sequentially connected to be unified, so that the guide rails corresponding to the entire travel of the hoistway are erected, and then a lifting machine is mounted on a ceiling member of the hoistway. After installing By lifting the car frame and driven by heavy equipment along the guide rail, from the car frame on,
Of the plurality of guide rail members, perform centering fixing of all other guide rail members except for an upper guide rail located above the hoistway and installation and fixing of equipment in the hoistway, and then, in the car frame. In a state where the cab is formed by incorporating the side plate, centering and fixing of the upper guide rail and installation and fixing of equipment in the hoistway are performed from above the cab.

According to the first aspect of the present invention, a single guide rail corresponding to the entire travel of the hoistway is erected, and then the car frame is lifted along the guide rail. After mounting the equipment in the hoistway from above the car frame to parts other than the upper part of the hoistway from above the car frame, the side plate is incorporated into the car frame to form a cab, and from the top of this car room The centering and fixing of the guide rail members and the installation and fixing of all hoistway devices located above the hoistway, such as the hoist, are performed. Thus, the equipment in the hoistway can be installed over the entire process of the hoistway without using the work floor device which is a temporary product. As described above, since only the main component need be installed without using the temporary component, the working efficiency can be improved and the equipment cost can be reduced.

According to another aspect of the present invention, there is provided the invention as set forth in claim 1, wherein one end of the lifting rope is connected to a bottom of the car frame. The cab is formed by incorporating a side plate, the other end of the lifting rope is temporarily held at the top of the cab, and then the hoist is installed and fixed at the top of the hoistway. The other end of the temporarily held hoisting rope is wound around the hoist and then hung, and the other end of the hoisting rope is connected to the hanging weight to perform a rolling operation. .

In the invention according to claim 2 of the present invention, one end of a lifting rope is connected to the bottom of the car frame in advance before the side plate is assembled to form a car room.
After installing the hoist on the upper part of the hoistway, the other end of the hoisting rope was wound around the hoisting machine, and then dropped, and the other end of the hoisting rope was connected to the hanging weight. Even if the method of installing the hoist from above the cab after forming the above cab in the elevator where the hoist is arranged, once lowering down the hoistway to connect the hoisting rope to the car side Without causing the car to be positioned above the hoistway, the other end of the lifting rope can also be connected to the hanging weight side. Thereby, when installing the elevator, it is possible to efficiently perform the work of rolling the lifting rope.
