Description

Large and extra-large elevators that prevent vertical opening and closing door panels from falling and shorten door opening and closing times

The present invention relates to large and extra-large elevators having vertical opening/closing doors, and more particularly, in large and extra-large elevators in which the weight of vertically opening and closing door panels ranges from several hundred kilograms to several tons, the time it takes to open and close the door It is possible to greatly improve the transport efficiency of the elevator by shortening the will be.

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.

Such an elevator can be divided into a machine room upper type in which a hoisting machine and a control panel are provided on a hoistway, and a machine roomless type in which a hoisting machine and a control panel are installed on a hoistway or guide rail.

And, in the building where the elevator is installed, an elevator passage is provided for the boarding car to go up and down.

1 shows an example of a conventional elevator, a boarding car 10 for passengers to board or loading cargo, a front car door 14 and a rear car door provided in front of the boarding car 10 ( 15), a counterweight 40 for maintaining a weight balance with the boarding car 10, a wire rope (W) connecting the boarding car 10 and the counterweight 40, and the boarding car ( 10) is configured to include a traction sheave 20 for driving.

The traction sheave 20 is installed together with a control panel in a machine room or a hoistway structure at the top of a building, and elevates the boarding car 10 while rotating in forward and reverse directions.

In addition, the boarding car sheave (S1, S2) is provided on the upper surface of the boarding car 10, the counterweight sheave (S3) is provided on the upper surface of the counterweight (C).

In the elevator of the above structure, one end of the wire rope (W) is fixed by the rope fixing part (F1) provided in the machine room above the boarding car 10, and is sequentially roped in S1 → S2 → traction sheave → S3 Then, the other end is fixed to the rope fixing part (F2) in the hoistway structure.

The wire rope (W) wound on each sheave is usually used in several strands, and the number of strands of the wire rope is increased or decreased according to the loading load of the elevator.

When the traction sheave 20 is rotated forward and reverse in the elevator having the above structure, the boarding car 10 is raised and lowered along the hoistway structure, and the counterweight 40 is raised and lowered in the opposite direction to the boarding car 10 . do.

However, the conventional elevator has a disadvantage in that it must be provided with a separate machine room for installing the driving unit and the control panel in the upper part of the hoistway.

In addition, a conventional general elevator is manufactured in a small size and installed in a hoistway inside a building, so that only a small number of people can ride it.

In order to solve the above problems, the present inventor proposes a super-large elevator that is installed in a semiconductor production plant, a display production plant, a shipyard, an offshore plant, etc. there is a bar

In addition, the present inventors have proposed, as shown in FIGS. 2 to 5, a high-load elevator installed outside of a building without a separate hoisting passage.

The conventional high-load elevator shown in FIGS. 2 to 5 includes a boarding car 10 for transporting passengers or cargo, boarding car doors provided in front and rear of the boarding car 10, and the boarding car ( 10) and a counterweight 40 for maintaining a weight balance, a plurality of wire ropes (W) connecting the boarding car 20 and the counterweight 40, and the boarding car by the wire rope (W) In a rope-type high-load elevator including a driving unit for driving, two masts (M) are vertically installed on both sides of the boarding car 10 without separately constructing an elevator passage of a concrete or steel structure.

On one side of each mast M, a guide rail 17 for guiding the lift of the boarding car 10 is provided.

And on the upper surface of the boarding car 10, a driving unit for driving the elevator is directly mounted.

In addition, a front car door 14 is provided at the front of the boarding car 10 , a rear car door 15 is provided at the rear, and a landing door 16 is provided on each floor of the building.

Also, as shown in FIG. 4, the front car door 14 and the rear car door 15 are configured in a vertical opening/closing type.

In the self-driving high-load elevator of the above-described structure, when the second traction sheave (S20)) is rotated forward and reverse on a traction machine, the passenger car 10 is provided on one side of both masts (M) It ascends and descends along the guide rail (17).

In addition, the counterweight 40 connected to the boarding car 10 by the wire rope W moves up and down in the opposite direction to the boarding car 10 inside the mast (M).

In this way, workers or equipment on the ground can be moved to a desired floor, and it is possible to move from the inside of the building to each floor.

The conventional elevator described above is not installed in the hoistway inside the building like a normal elevator, but the boarding car 10 is installed between two masts M provided on the outside of the building wall 18 .

Accordingly, since it is not necessary to provide a separate machine room and a hoistway, the construction cost can be reduced.

In addition, the height of the elevator can be easily adjusted by assembling and dismantling the mast (M), and there is an advantage that an elevator without a machine room can be easily installed even at a site where it is difficult to secure a driving unit installation space in the upper or lower part of the hoistway.

In addition, since the boarding car 10 is manufactured in a very large size, it is possible to transport dozens to hundreds of people at a time, and it is also possible to transport large cargo.

However, as a result of actually installing and using the above-mentioned high-load elevator, the following disadvantages were found.

First, since the door panel is manufactured in a very large size, the time required to open and close the door becomes longer.

The conventional elevator shown in FIGS. 2 to 5 has the advantage of being able to transport a large number of passengers and cargo at once because the boarding car is manufactured in a very large size.

That is, since the weight of the door panel ranges from several hundred kilograms to several tons, there is a disadvantage that it takes a lot of time to open and close it.

The total operating time of the elevator can be divided into (a) door opening time, (b) passenger boarding time, (c) door closing time, and (d) inter-floor operating time.

For example, if the inter-floor height is 10 m, the elevator door height is 6 m, the elevator operating speed is 60 m/min, and the door opening/closing speed is 0.2 m/sec, the total operating time of the elevator is (a) about 30 seconds of door opening time, (b) Boarding time approximately 1 minute, (c) Door closing time approximately 30 seconds, (d) Inter-floor operation time approximately 10 seconds.

If it is assumed that a 10-story building stops at every floor, (a) door opening time is about 300 seconds, (b) boarding time is about 10 minutes, (c) door closing time is about 300 seconds, (d) further operating time It takes about 90 seconds, which takes a total of 21 minutes and 30 seconds.

That is, the time required to open and close the door becomes 10 minutes from the total operating time of the elevator of 21 minutes and 30 seconds, and approximately half of the total operating time is consumed to open and close the door.

As a result, the original purpose of a super-large elevator to quickly transport a large number of passengers and cargo at once is overshadowed.

That is, the conventional large and extra-large elevators have a disadvantage in that the opening and closing time of the boarding car door and the platform door takes longer than the operating time of the elevator, thereby lowering transportation efficiency.

Second, the conventional large and extra-large elevators have a disadvantage that the door panel itself weighs several hundred kilograms to several tons, so that a large accident may occur when the door panel falls during the door opening and closing process.
