Description

[Detailed Description of the Invention] This invention relates to the structure of a drum-type elevator system mainly installed in small-scale buildings.

In apartment complexes and small office buildings constructed in urban areas, elevator equipment that does not require the installation of a penthouse on the roof is required to avoid violation of sunlight rights. On the other hand, there are basement type elevators which are rope traction type and have a driving machine installed in the lower part of the building, and hydraulic jack type elevators. However, in the former case, the middle part of the rope that connects the car and the counterweight is driven by a hoist, so roping becomes complicated, as many guide wheels are installed at the top of the elevator hoistway to guide the rope downward. Moreover, it requires a lot of space even on a plane, making it difficult to install an elevator and making it expensive. Furthermore, the latter has the disadvantage that it does not have a counterweight, which increases the total load of the car, which consumes a lot of energy and increases maintenance costs.

This invention solves the above-mentioned drawbacks and aims to provide a drum-type elevator system that does not require a penthouse in the upper part of a building and is simply constructed and easy to install.

An embodiment of this invention will be described below with reference to FIGS. 1 and 2.

In the figure, 1 is an elevator hoistway installed in a building, 2 is a car that goes up and down guided by rails 3 installed in the hoistway 1, and 2a is a car that does not have a part of the car 2 and is attached to the bottom surface of the car 2. 4 is a machine room provided adjacent to the lower part of the hoistway 1; 5 is a drive machine installed in the machine room 4; 5a;
6 is a counterweight that is guided up and down by a rail 7 installed in the hoistway 1, and 8 is a counterweight that is pivotally attached to the upper part of the hoistway 1 and is attached to the end of the support body 2a near the machine room 4. The first guide car placed at the upper corresponding position, 9
10 is a second guide wheel pivotally attached to the upper part of the hoistway 1 and placed at a corresponding position above the end of the support body 2a opposite to the machine room 4; 10 is wrapped around the first guide wheel 8, and one end is a supporting member 2a, and the other end is fixed to the winding drum 5a, the first main rope 11 is wound around the second guide wheel 9, and one end is connected to the support member 2a, and the other end is connected to the counterweight 6. This is the second main rope.

That is, the first main rope 10 is arranged on one side of the car 2, the second main rope 11 is arranged on the other side, and the car 2
is supported by a drive machine 5 and a counterweight 6, and the drive machine 5 is energized to move the car 2 up and down. The weight of the counterweight 6 is set to be slightly lighter than the weight of the car 2, so that the weight of the counterweight 6 is lowered by the weight of the car 2 even when the car 2 is not loaded. The first and second main ropes 10 and 11 of the car 2 are separated from each other.
Since it is supported by the roping, the device can be easily roped and can be installed in a small amount of space. In addition, in elevators for small buildings, the number of users per elevator is small, and when operating two cars, there are only one passenger.
In many cases, there are one or two passengers, and when car 2 is operated in response to a hall call, there are often no passengers in car 2. On the other hand, even if the elevator is in a small building, the capacity is 6 to 9 people, taking into consideration the transportation of luggage.
Names will be installed. On the other hand, in the case of a rope traction type elevator, the weight of the counterweight is set to a value such that the car is loaded with 40 to 50% of the rated load capacity, so it is operated in a state close to no load. In elevators for small buildings, which are often used, energy consumption can be reduced by setting the weight of the counterweight 6 to a value close to that when there is no load in the car 2. By making the counterweight 6 slightly lighter than the car 2's own weight, the brake (not shown) of the drive unit 5 can be released and the car 2
Since the winding drum 5a type drive machine 5 can be lowered, the winding drum 5a type drive machine 5 can be used.

As explained above, this invention provides a first main rope fixed to the drum of the drive machine on one side of the car, and a second main rope connected to the counterweight on the other side,
The car is supported by first and second main ropes that are separated from each other, and the weight of the counterweight is set to be lighter than the car's own weight. As a result, the first and second main ropes can be easily roped and installed in a small space, and can be manufactured at low cost.In addition, when operating under light loads, energy consumption is low and operating costs are reduced. This is to realize a winding drum type elevator device that can perform the following functions.
