Field of the Invention [0001] The present invention relates to an elevator roping apparatus, and more particularly, to a roping apparatus of an elevator system which applies a roping system of a specific structure to an elevator roping apparatus constituting an elevator system, The present invention relates to an elevator roping apparatus for reducing a hoistway space of an elevator in which a useful area of a building can be enlarged as much as a space.

Further, the present invention relates to an elevator roping apparatus in which a balance weighting device and an elevator car roofing device are installed in one frame space to reduce the installation space and simplify the construction of the elevator.

2. Description of the Related Art Generally, an elevator used in a building such as a residential or commercial building has a vertically oriented elevator inside a building, and travels up and down along the elevator with an elevator car and a balance.

The elevator car and the balance weight moving up and down along the hoistway have the same traveling distance, and accordingly, the same traveling space is required.

As a result, the required area of the hoistway is occupied by the elevator car and the weight of the balance weight, thereby causing a problem of reducing the area of the building. The economic loss of the elevator car increases exponentially with the increase of the building size and the building cost I had a problem that was a great burden to the client.

In order to solve the above problems, Japanese Unexamined Patent Application Publication No. 10-2015-0137569 (published on Dec. 09, 2015), Japanese Unexamined Patent Application Publication No. 2006-151644 (published on June 15, 2006) No. 2010-116254 (published on May 27, 2010), the elevator car and the balance weight are subjected to a specific structure of the roping system to reduce the traveling distance of the balance weight to 1/2 of the elevator car travel distance, The elevator structure for saving space is provided.

However, the above-mentioned patent still uses the space of 1/2 of the hoistway as a traveling space of the balance weight, and has the same problem.

In addition, in recent years, there has been an increasing tendency to install transparent glass on the outside of a building for the purpose of enhancing the exterior appearance of a building. However, by installing a door on the inside of the building in this case, There is a possibility that the shape of the additional upper and lower run is exposed as it is, and the aesthetics may be damaged, and also the outer view is obstructed and the installation of the door is also limited.

The present applicant has filed a patent application 10-2017-0043548 for solving the above problems.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to dramatically shorten the travel distance of the balance weight and to provide a weight balance outside the hoistway, thereby reducing the space of the hoistway and using the exclusive area of the building as wide as possible.

In addition, the balance weight and the traveling means are installed at the same place at the same time, so that the maintenance and the maintenance such as the maintenance are convenient, and the installation of the viewpoint and the entrance is not obstructed.

In addition, a winding drum, an elevator car, and a winding drum of a balance weight and a transmission means are simultaneously formed in one frame to simplify the structure of the balancing machine by omitting the installation distance of the balance weight and unnecessary installation space and components. The present invention can provide an economical and eco-friendly elevator roping apparatus by reducing noise and vibration by reducing the travel distance of the balance weight, and by reducing the length of use of the wire.

In order to achieve the above object, according to the present invention, the balancing means for balancing by the fixing roller and the moving roller of the applicant of the present application is used as the hoisting means of the elevator and the balancing means of the balance, By replacing the rope for elevator driving and the rope for traveling the balance, it is possible to shorten the roping distance of the balance weight to further extend the traveling distance of the elevator, and the roping device of the balance weight can be installed on the roof, It can be installed in the machine room. By excluding the balancing hoistway from the hoistway of the elevator, it is possible to maximize the utilization of the building by making it possible to use the exclusive area of the building widely, Maintenance and so on. Will.

In the first embodiment of the present invention, the roping apparatus is installed outside the machine room. The elevator roping apparatus includes an elevator rope winding drum having a large diameter and a balance rope winding drum having a small diameter, By shortening the weighting distance of the counterweight.

Further, the elevator winding shaft and the counterweight winding drum may be separated from each other to provide a transmission gear, whereby the rotation speed of the drum can be adjusted to adjust the roping distance of the elevator and the balance weight.

And the difference in the number of gears of the transmission gear is used to shorten the roping distance of the balance weight.

Further, by additionally providing a transmission gear between the elevator take-up drum shaft and the shaft of the balance take-up drum, the weighting weight can be further shortened.

In addition, when the machine room of the elevator is narrow when the elevator is replaced, only the balance weighting device may be installed outside the machine room.

The elevator roping apparatus structure of the first embodiment of the present invention is such that a large-diameter elevator rope-winding drum and a small-diameter balance-winding drum are equally rotated in a shaft rotated by a bearing fixed to a frame.

The rope connected to the elevator is fixed to the elevator rope winding drum, the rope connected to the balance weight is fixed to the balance take-up drum, and the balance weight and the elevator move upward and downward by the power of the hoisting machine, Repeat the action of winding and loosening.

The elevator roping structure of the second embodiment of the present invention is characterized in that the rope connected to the elevator is fixed to the elevator rope winding drum and the rope connected to the balance weight is fixed to the counterweight winding drum, During the downward movement, the rope is wound in the opposite direction to each winding drum, and the rope distance of the balance weight is controlled by the gear ratio of the transmission gear ratio and the diameter ratio of the winding drum.

Other constructions apply general elevator constructions.

The traveling distance of the balance weight is determined by the circumference of the elevator rope winding drum and the circumferential speed ratio of the balance rope winding drum.

That is, when the diameter of the elevator rope winding drum is 1 m (1 * 3.14 = 3.14 m) and the diameter of the balance rope winding drum is 10 cm (0.1 * 3.14 = 0.314 m), the traveling distance of the balance weight is 1/10 do.
