Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circulation type elevator in which a plurality of baskets grip a main rope and operate within one loop.

[0002]

2. Description of the Related Art FIG. 6 is a diagram showing an outline of the structure of a circulation type elevator. Generally, elevators that are operated in buildings are driven by a rope type that winds or unwinds a rope that suspends a riding basket around a drum to elevate the riding basket, or by using a counterweight and a rope and hoisting sheave. There is a traction system that is driven by the frictional force between them. In contrast to such a conventional elevator, a plurality of riding baskets 41 to 44 can be installed in an operation path forming one loop by connecting an up operation path and a down operation path up and down as shown in FIG. Several circulating elevators configured to operate have been proposed. For example, Japanese Patent Laid-Open No. 4-182292 proposes a circulation type elevator in which a plurality of riding baskets are guided and circulated on an endless rail. On the other hand, Japanese Patent Application No. 6
No. 167764 proposes a circulation type elevator in which a riding car is continuously circulated by a main rope and a plurality of circulating riding cars can be independently driven. this is,
Two parallel main ropes that are wound around a driving wheel and a deflecting wheel to form a loop having an ascending portion, a descending portion, and upper and lower horizontal portions, and are connected across the two main ropes. A circulating loop is formed by the riding basket rotatably attached to the connecting beam, and a plurality of circulating loops are formed to coaxially support the drive wheel and the deflecting wheel at each position. And
A drive source for independently driving the drive wheels is provided for each circulation loop to circulate the riding basket in one direction, and the connecting beam is mainly located at a position away from the outer edge of the drive wheels and the deflector wheels. It is connected to the rope. As described above, the circulation type elevator is greatly different in that a plurality of riding baskets operate in one loop, and a large transportation capacity can be obtained with a small lifting area.

[0003]

However, the above-described circulation type elevator having a mechanism of only one loop has a drawback that the ascending / descending stroke is limited by the load limit of the chain or rope. Therefore, when installing in a high-rise building, it is not possible to operate to the top floor in one loop, and in one circulation type elevator, it is divided into multiple groups up to the top floor and floors included in each group It can only be operated. Therefore, when moving between the lower floor and the upper floor, several circulating elevators must be connected. Therefore, there is a problem that not only non-stop and express operation from the lobby floor to the top floor and upper floors are not possible, but also there are many connections on the middle floor, and the service in the skyscrapers deteriorates significantly. Moreover, in the conventional circulation type elevator, only one type of basket can be operated in one service route, and the number of baskets in one service route is also determined. In addition, the maintenance of the basket and rope is done during operation and when the floor where the basket does not come is opened, it is necessary to consider safety.

[0004]

SUMMARY OF THE INVENTION The present invention is to solve the above-mentioned problems and to freely control the type of basket and the number of operating cars.

Therefore, in the present invention, in a circulation type elevator in which a plurality of baskets grip and operate the main ropes in one loop, each cage is provided with a gripping mechanism for gripping and releasing the main ropes, and It is characterized in that a basket stock yard for stocking baskets is provided and the baskets are moved in and out of the basket stock yard through a lead-in line. The feature is that the car is made selectable and the number of cars in the car is controlled to increase or decrease according to the schedule operation.

It is possible to operate from the upper floors and lower floors of the first building 2 through the connecting portion 23 from the upper floors of the second building 22.
It is also possible to operate to the upper and lower floors of 2. Such an operation pattern may be switched depending on, for example, a time zone, or may be performed in response to a call for a riding basket or a floor call. As a matter of course, in the grab type circulating elevator according to the present invention, it is possible to operate a plurality of riding baskets as described with reference to FIG. By using the information, it is easy to carry out comprehensive processing of information on the operating intervals of the riding baskets, calls of the riding baskets, and floor calls, and to switch the safe driving pattern.

FIG. 5 is a diagram for explaining an example of operation control of the grip type circulating elevator according to the present invention. Now, as shown in FIG. 5, it is assumed that three riding baskets 31a to 31c are stopped at the loop for horizontal movement of the underground machine room, and at the first floor BF and the sixth floor 6F, respectively, and the central control panel 3
3 controls the drive of the motors 32a to 32c and the gripping mechanism (not shown) by monitoring the signal from the call button 34 on each floor. Here, when a call is generated on the 7th floor, the central control panel 33 drives the motor 32c to raise the riding basket 31c to stop it at the 7th floor. Next, when a call occurs on the 5th floor, the central control panel 33
Drives the motor 32b to raise the riding basket 31b, and when the riding basket 31b passes 2F, the motor 32c
Also drives. Then, in the gripping section of 4F, the gripping mechanism of the riding basket 31b is controlled to grip from the loop 33b to the loop 33c, and stopped at the position of the fifth floor.

When the call button 34 of each floor is operated as described above and the ride baskets 31a to 31c are selected and stopped at the position of the predetermined floor where the call is generated, then the ride basket is used. Since the person operates the basket call button to select the destination, the same operation control is performed up to the floor of the destination in this case as well. For that purpose, although not shown, a signal of a car call button is also input to the central control panel 33 from each of the riding baskets 31a to 31c.

It should be noted that the present invention is not limited to the above embodiment, and various modifications are possible. For example, in the above embodiment, the main rope is used, but instead of this, a chain may be used. Further, it goes without saying that the gripping-type circulating elevator of the present invention is naturally provided with control devices such as sensors for detecting the traveling position of the riding basket, safety devices, etc., which are conventionally provided in elevators. . Further, although the basket stock yard is provided on the basement floor, it may be provided on the upper machine room or the intermediate floor.

[0015]

As is apparent from the above description, according to the present invention, the basket is provided with the grip change mechanism for gripping and releasing the main draft rope, so that a plurality of baskets can be operated in one operation path and You can freely change the number and type. Therefore, the service route can be used for multiple purposes, and the number of service routes can be reduced. In addition, since the number of baskets can be controlled according to the demand, the number of cars can be increased during peak usage and can be reduced during off-peak hours, thus reducing running costs. Furthermore, since maintenance can be performed in the machine room where the basket stockyard is provided, maintenance of the basket and rope can be performed in one place.
