Description

Elevator for high-rise buildings {elevator for high-rise buildings}

The present invention relates to a hoisting device for a tall building. More specifically, the present invention is a hoisting device for the inter-floor transportation of a high-rise building, by connecting one or more cages mounted on each of the two-row hoistway, which is a vertical passage in the building, with a main rope. It relates to a hoisting device for a high-rise building that is lifted in opposite directions.

In general, an elevator or lift refers to an inter-floor means of transporting people and / or cargo using a cage that runs along a hoistway, a vertical passageway in a building. (escalator), moving walkway, wheelchair lift, etc., but common consultation refers to passenger or freight elevators.

In recent years, as the various living environments for living and working have risen, elevators have become a vertical means of transportation that are indispensable for everyday life. Various developments are being made to satisfy gender, safety, economy and convenience.

On the other hand, the lifting device is divided into a hydraulic type and a rope type according to the driving method, the former hydraulic type is to lift the cage by the plunger (plunger) to move up and down by a hydraulic pump (hydraulic pump). Because of this, there is a big limitation in stroke distance and speed, so it is currently used only in small buildings less than 20m.

On the other hand, the latter rope type is connected to both ends of the hoist rope wound on the pulley of the traction machine by connecting the cage and the counter weight to the pulley and the main rope according to the rotational force of the hoist. Lift the cage with the friction force between. Because of the limited stroke distance, high speed operation and low power operation, it is currently applied to most high-rise buildings.

Therefore, hereinafter "elevating device" refers to the elevator of the rope-type lifting device unless otherwise specified, which has the same meaning consistently herein.

1 is a schematic view showing a schematic structure of a general lifting device.

As can be seen, the machine room located on the uppermost floor of the hoistway is provided with a hoisting machine 4 connected to the electric motor 2, thereby a rotating pulley 6, and a control panel 10 for various control functions. The main rope 12 connecting the cage 20 and the counterweight 30 to the pulley 6 is wound in a pulley manner, while the cage 20 and the counterweight 30 are mounted along the inner longitudinal direction of the hoistway. Guide rails (14) and weight rails (16) are provided to guide the lifting and lowering of the cage 20 and the counterweight 30, respectively.The lowermost layer of the cage 20 and the counterweight 30 Cage buffers (42) and weight buffers (44) are located to absorb and disperse kinetic energy when descending.

Therefore, the general lifting device converts the rotational movement of the pulley 6 into a linear motion with the main rope 12 to elevate the cage 20 and the counterweight 30 in opposite directions, and when the cage 20 is stopped on a desired floor. The cage door 22 of the cage 20 and the elevating door (not shown) of the floor are interlocked to open and close people and cargo.

However, the general hoisting device exhibits a so-called 'single-deck' method in which one cage 20 runs along one hoistway, thereby lowering transportation efficiency and space efficiency.

Therefore, in recent years, two or three cages connected up and down together operate a single hoistway with a double-deck or triple-deck 'multy-deck' system. This was also introduced. Theoretically, the double deck type is more than twice as efficient as the single deck type, and the efficiency is increased by about 2.5 times in consideration of the integration function of individual parts, operation and maintenance cost, and productivity.

However, the multi-deck lift device is also required to add a balance, like the single deck method, and is accompanied by a weight increase by a plurality of cages, so a relatively high load balance is used. Therefore, the multi-deck hoisting device consumes much more power for unit distance operation than the single deck, and in the case of a high-rise building having more than 100 floors, it is inevitably high in power consumption.

In addition, the multi-deck hoisting device exhibits unexpected problems, such as increased fire risk, which has been pointed out as a traditional problem in the field.

Prior to the full description, the elevating device for a high-rise building according to the present invention (hereinafter, referred to simply as an elevating device) may be divided into several embodiments according to specific configurations and functions, and thus, each of them will be described. At this time, for convenience, instead of looking at the contents common to each embodiment in detail through the first embodiment, other embodiments mainly look at the difference.

First Example

2 and 3 are views showing a lifting device according to a first embodiment of the present invention, respectively, FIG. 2 is a perspective view and FIG. 3 is a plan view.

Based on this, the core technical idea of the present invention will be briefly described as follows.

First, the hoisting apparatus according to the present invention requires two rows of hoistways A and B, and the two hoist hoists A and B are connected to each other through the uppermost machine room C. At this time, the machine room (C) is provided with various components for the operation and safety of the elevating device together with the electric motor 52 and the hoisting machine 54, the control device 60, the control device.

The first and second cages 80 and 90 are mounted on the hoisting paths A and B in two rows, respectively, and the first and second cages 80 and 90 are pulley type to the pulley 56 of the hoist 54. It is connected to the main rope 72 wound. In this case, the first and second cages 80 and 90 each have a single-deck subcage (optionally denoted as 82,92, which is the same below) corresponding to the individual floors of the skyscraper. The sub-cages 82 and 92 are provided with cages 84 and 94 which are interlocked with the lifting doors in each building.

In addition, the first and second cages 80 and 90 are connected by separate power generation ropes 74, and the power generation ropes 74 are generators 100 installed in the hoistways A and B or the machine room C. The armature of the rotor (102) is pulleyed. At this time, the power generated by the generator 100 is appropriately supplied to the necessary place, such as the electric motor 52, the hoist 54, the control panel 60.

That is, the lifting device according to the present invention converts the rotational movement of the pulley 56 by the electric motor 52 and the hoist 54 to a linear movement of the main rope 72, by using the two rows of hoistway (A, B) The first and second cages 80 and 90, which are mounted in each of the two cages, are lifted in opposite directions to each other, so that the rotation direction and the degree of rotation of the pulley 56 are properly controlled so that the first and second cages 80, When the vehicle stops at the desired floor, the cage doors 84 and 94 mounted on the sub-cages 82 and 92 and the lifting doors of the corresponding floors are interlocked and opened so that people and cargo can get on and off simultaneously on multiple floors. . During this process, electric power is generated from the generator 100 by lifting up and down the first and second cages 80 and 90 and re-supplied to the electric motor 52, the hoist 54, the control panel 60, and the like.

As a result, the lifting device according to the present invention shows a high transport efficiency and low power drive.

Hereinafter, the details will be described with reference to the drawings separately mentioned with reference to FIGS. 2 and 3.

First, two rows of hoistways A and B are vertical passages penetrating the floors of a high-rise building, and for convenience, divided into first and second hoistways A and B. Or it may show a form divided into front and rear. However, the first and second hoistways A and B are not necessarily limited thereto, and if connected to each other through the uppermost machine room C, it is also possible to utilize two vertical passageways at different locations in the building.

This can be easily understood by referring to the description below.

Next, the machine room C is a top floor space for connecting two rows of hoistways A and B. An electric motor 52 and a hoist 54, a control panel 60, a control device, and a governor, a safety device, are connected to each other. 62,66).

At this time, the electric motor 52 supplies power to the hoisting machine 54, and the hoisting machine 54 rotates the pulley 56 by the power of the electric motor, through the main rope 72 wound on the pulley 56, and the first and second motors. The second cages 80 and 90 are elevated. The control panel 60 includes a driving method of direct current (Fire Leonard, stop Leonard, etc.) or alternating current (AC single speed control, AC two speed control, AC feedback control, variable frequency variable voltage control, etc.), sensing signals of various sensors, and predetermined The electric motor 52 and the hoist 54 are controlled in accordance with an algorithm.

In addition, the governors 62 and 66 adjust the lifting speeds of the first and second cages 80 and 90 while cutting off the power of the electric motor 52 and actuating a break if necessary. To this end, preferably, first and second governors 62 and 66 for adjusting the lifting speed of each of the first and second cages 80 and 90 are separately used, and the first and second cages 80 and 90 are used separately. Is one-to-one correspondence with the first and second governors 62 and 66 via separate first and second governor ropes 74 and 76, respectively, which are separated from the main rope 72.

For reference, although a conventional governor is classified into a disc type and a flyball type, it is not particularly limited in the present invention, and an appropriate kind may be used according to the purpose.

Next, the first and second cages 80 and 90 are mounted in the first and second hoistways A and B, respectively, which are pulley-style wound around the pulley 56 of the hoist 54. Are connected to each other. In this case, at least one auxiliary pulley 58 interlocked with the pulley 56 may be used according to the distance between the first and second hoistways A and B.

Therefore, when the pulley 56 includes the pulley 56 and the auxiliary pulley 58, which is the same below, the rotation of the first and second cages may occur due to the friction force between the pulley 56 and the main rope 72. When the 80 and 90 are lifted in opposite directions and the pulley 56 stops, the first and second cages 80 and 90 stop.

In this case, in particular, the first and second cages 80 and 90 of the elevating device according to the first embodiment of the present invention have one or more sub-cages 82 and 92 of the single deck corresponding to the individual floors of the skyscraper. Multi-deck cages connected in series are formed.

Therefore, in the present invention, the ten sub-cages 82 are connected up and down to propose a form corresponding to ten floors of a building, and the form can be conveniently used by a user familiar with decimal method.

This is discussed in detail in the relevant sections.

In addition, each of the sub-cage 82 is provided with a cage (84) is interlocked with the elevator door for each floor in the building, the cage (84) is made of a standard and material according to the design rules of the fire door. In addition, at least one of an oxygen supply device 86 and an air purifier 88 is installed at each ceiling of each of the sub-cages 82 to supply oxygen to the corresponding sub-cage 82 in case of an emergency such as a fire or the like. 82) Purify the air flowing into it.

The above structure is to effectively cope with an emergency situation such as a fire, and the first and second cages 80 and 90 of the elevating device according to the present invention can be carried by a relatively large number of people compared to that of a single deck. Given that there is.

Next, the first and second cages 80, 90 are connected by separate power generation ropes 78, which are pulleyed around the rotor 102 of the generator 100.

At this time, the generator 100 may be two or more plural, and each rotor 102 is rotated together when the first and second cages 80 and 90 are wound together by a power rope 78 wound in a pulley manner. Generates a predetermined power. The electric power generated by the generator 100 is appropriately distributed to the required place such as the electric motor 52, the hoist 54, the control panel 60, and the like.

Lastly, first and second guide rails 112 and 114 are installed to guide the lifting of the first and second cages 80 and 90 along the inner longitudinal directions of the first and second lifting paths A and B. In the lowermost layer of the first and second hoistways A and B, first and second shock absorbers 122 and 124 absorb and disperse kinetic energy of each of the first and second cages 80 and 90 for safe stop. Although not shown in the drawings, upper and lower limit switches limiting the highest and lowest lift heights of the first and second cages 80 and 90 on one side of the first and second hoistways A and B. switch) can be installed.

In this case, since the guide rails 112 and 114, the buffers 122 and 124, and the limit switch may be based on the general technical contents, a separate description is omitted.
