The present invention is an improved invention of Korean Patent Application No. 10-2009-28731 filed by the present applicant.

Korean Patent Application No. 10-2009-28731 has been granted the patentability of claims 1 to 3 in the notice of opinion sent out on June 19, 2009.

The present invention is an improved invention for the configuration that is recognized in the patent application No. 10-2009-28731.

The present invention relates to an elevator hoisting structure, and in particular, a hoistway, a beam fixedly installed on an inner wall of the hoistway, a first roller fixedly bolted to the beam, and the hoistway moving up and down. It includes a cage, a hoist that is fixedly coupled to the upper outer side of the cage, a hoisting machine including a rope for moving the cage up and down, and a second roller is provided on the upper side and a balance weight to which the rope of the hoisting machine is connected. The end of the rope of the hoisting machine is fixed to the beam, the hoisting rope is hung on the first roller and the second roller, the housing is the front and rear plates and the front plate and respectively disposed in front and rear and It includes an upper plate installed on the upper plate, and at least one of the front plate and the rear plate are formed through holes through which the hoist Group, to a hoisting machine of an elevator traction machine mounting structure which is fixed to the housing.

In general, when building a high-rise apartment or office high-rise building, the building is inevitably installed an elevator, which is a vertical transportation means, and the elevator is a vertical lift, which is formed in a rectangular parallelepiped shape of the building Each layer is formed with an opening in communication with the hoistway.

As shown in FIG. 1A, the hoistway 20 includes a cage 24 and a rope 34 wound around the hoist 32 moving the cage 24 and having a counterweight 26. Guide rails (not shown) for guiding the up and down movement of the cage 24 or the counterweight 26 are installed, while control cables connecting the cage 24 and the control panel and indicators for indicating the position of the cage 24 are provided. Etc. are provided, and a door device is provided at each opening 22 of the hoistway 20.

The structure of the hoistway in which the elevator is installed is different depending on whether the machine room is provided at the top of the hoistway, which will be described with reference to FIGS. 1A through 2B.

FIG. 1A is a schematic perspective view showing a hoisting installation structure of an elevator equipped with a machine room, and FIG. 1B is a cross-sectional view taken along line AA of FIG. 1A. It is a typical structure that is installed a lot in the conventional structure.

However, the structure in which the machine room 30 is separately installed in the upper part of the hoistway, and the hoisting machine 32, the control panel, the governor, etc. are installed in the machine room 30 has a construction cost increase, the amount of sunshine, and the high limit according to the machine room 30 installation. Therefore, there is a problem that there is a problem of spatial limitation because the machine room should always be considered in the effective use of the building roof and construction of the building.

Accordingly, in order to solve this problem, the hoist 32 is installed on the hoistway wall in the hoistway as shown in FIGS. 2A and 2B without forming a separate machine room in which the hoist is installed on the hoistway. As the rope is suspended on (36), an elevator that does not require a separate machine room on the upper part of the hoistway is called an MRL (Machine Room Less Elevator).

The advantages of an elevator without a machine room are as follows.

(1) When comparing the space occupancy of the existing rope-type and hydraulic elevators, machines such as hoisting machines (power units in the case of hydraulic type), control panels, and governors installed inside the machine room constructed near the top of the building or near the hoistway are included in the hoistway. It does not require a separate machine room for construction.

In particular, by integrating and minimizing the elevator accessories, the machine room equipment of the elevator machine room can be installed in the hoistway so that there is no need to construct the machine room, thereby making the most of the space in the building, thereby achieving breakthrough building efficiency.

(2) Since the construction and equipment work related to the machine room, which was required for the existing rope-type and hydraulic elevators, are unnecessary, the construction period and cost can be reduced, as well as convenience in construction work.

(3) The gearless hoist which adopts the high efficiency permanent magnet synchronous motor system can be used to minimize the electric motor capacity and reduce the power equipment and power consumption of the elevator.

(4) Since there is no machine room, there are few constraints in terms of building height, so the design of the building exterior can be diversified.

In particular, it is not only widely used in various legal regulations such as altitude restrictions, but also meets the current trend in terms of urban design.

According to the installation structure of the Traction Machine, the conventional Machine Room Less Elevator (MRL) can be largely classified as follows.

1. There is a structure for installing the hoist on the hoistway wall of the hoistway or lower, such a structure has the following disadvantages.

1) Since the hoist must be installed in the wall of the hoistway, the load on the hoist is transferred directly to the building, which adversely affects the structure of the building.

2) As the elevator is installed, it is difficult to install the elevator because it is necessary to drill a hole in the wall and install the anchor.

3) Since the hoisting machine is required to be installed on the upper or lower part of the hoistway, the elevator installation period becomes longer.

4) During operation of the elevator, vibrations generated from the hoist that moves the cage (or car) up and down inside the hoistway are transmitted to the building along the hoistway wall, thereby inevitably damaging residents due to noise and vibration. .

2. Another method is to install a hoist on a separate guide rail (Guide Rail), such a structure has the following disadvantages.

1) An additional guide rail having a length corresponding to the length of the hoistway is to be additionally installed on the hoistway to support the hoisting load.

2) Since the load on the hoist must be supported by the guide rail, there is a possibility that the guide rail is deformed.

3) Therefore, the guide rail should be made of sturdy ones by installing the hoisting machine, thus incurring additional material cost and additional installation cost.

4) When the elevator starts up, noise and vibration damage are inevitable to residents because vibration generated from the hoist is transmitted to the building through the guide rail.

The present invention has been made in order to solve the above problems, it is not necessary to install a hoist on the wall of the hoistway, it is not necessary to penetrate the hoistway wall, the guide rail can be replaced with a lightweight guide rail, the installation of the elevator becomes easier, the elevator The purpose of the present invention is to provide an elevator hoisting installation structure which can shorten the installation period and reduce installation cost, and minimize the overhead that may be increased by installing a hoist in a housing serving as a bulk.

The lifting device installation structure of the elevator of the present invention for achieving the above object, the lifting roller, the beam is fixed to the inner wall of the hoistway, the first roller is fixed to the beam, and the hoistway to move up and down It includes a cage, a hoist that is fixedly coupled to the upper outer side of the cage, a hoisting machine including a rope for moving the cage up and down, and a second roller is provided on the upper side and a balance weight to which the rope of the hoisting machine is connected.
