Description

A rope-type self-driving elevator that does not require a machine room {ROPE TYPE SELF-DRIVING ELEVATOR WITHOUT MACHINE ROOM}

The present invention relates to a rope-type self-driven elevator that does not require a machine room, and more particularly, a rope-type elevator in which a drive unit and a control panel are mounted on the passenger car itself in an elevator that goes up and down by a wire rope so that there is no need to install a separate machine room It is about self-driving elevators.

In general, elevators are installed in high-rise buildings, etc. to transport people or cargo to a desired floor while ascending and descending in a vertical direction.

1 shows an example of such a rope type elevator.

The conventional rope elevator, as shown in Figure 1, a passenger car 20 for boarding or transporting cargo, and a counterweight 40 for maintaining a weight balance with the boarding car 20 And, a wire rope 50 connecting the boarding car 20 and the counterweight 40, a driving unit 31 for driving the traction sheave 31a on which the wire rope 50 is wound, and the wire rope ( It is configured to include an intermediate sheave 33 for guiding the 50 , and a control panel 32 for controlling the elevation of the boarding car 20 .

Here, the driving unit 31 , the intermediate sheave 33 , and the control panel 32 are installed inside the machine room 30 provided above the vertically formed elevating passage 10 .

And one end of the wire rope 50 is fixed to the upper portion of the boarding car 20 , and the other end is fixed to the upper portion of the counterweight 40 .

When the traction sheave 31a is rotated forward and reverse in the elevator having the above structure, the boarding car 20 is raised and lowered along the lift passage, and the counterweight 40 is raised and lowered in the opposite direction to the boarding car 20 do.

However, the conventional elevator should have a separate machine room 30 for installing the driving unit 31 and the control panel 31 on the upper part of the elevator passage.

Accordingly, there are disadvantages in that the construction cost is increased, the installation time of the elevator is delayed, and the aesthetic feeling is deteriorated.

In addition, when an elevator is temporarily installed to transport workers and equipment at a construction site, there is a problem in that it is difficult to raise or lower the height of the elevator due to the machine room 30 provided in the upper part of the elevator passage 10 .

As a method to solve the above problems, as shown in FIG. 2 , an elevator without a machine room may be installed, which is usually referred to as a machine room less elevator.

Figure 2 shows an example of such a machine roomless elevator.

In the conventional machine roomless elevator, the driving unit 31 for driving the elevator is installed on one side of the upper side of the guide rail (not shown), and the control panel 32 is installed on the side of the hoistway wall.

According to the above-described machine roomless elevator, there is an advantage in that it is not necessary to provide a separate machine room in the upper part of the hoistway 10 .

Meanwhile, there is also a machine roomless elevator in which the driving unit 31 is installed on the lower floor of the hoistway 10 .

However, the conventional machine roomless elevator has a problem in that it is difficult to install when it is difficult to secure a driving unit installation space in the upper or lower portion of the elevator passage 10 .

In addition, when it is necessary to adjust the height of the elevator, there is a disadvantage that it cannot be actively responded to.
