Problems solved by technology

[0008] In the existing traction machine of an elevator, there is a driving device and a braking device arranged coaxially with the traction machine, and the braking device is located outside the driving device, so the axial length becomes large
In addition, since the traction machine is installed in the lower part of the hoistway, there is a problem that the use of hoistway equipment such as anti-rope pulleys and ropes increases, and the space on the plane of the hoistway increases, so the cost tends to increase.
In addition, when the traction machine is installed on the top of the hoistway, the operator needs to climb on the car to perform maintenance and inspection of the brake device, so the maintenance and inspection work is very difficult. At the same time, measures must be taken to prevent the operator from failing Protective measures against head hitting the ceiling of the hoistway due to the expected lift of the car

Abstract

An elevator apparatus enabling the easy maintenance and inspections of a braking device by installing a hoist so that a drive device and a braking device are separated from each other to reduce the installation space for the braking device in a hoistway. The hoist is separated into the drive device and the braking device, and the separated drive device is mounted on an upper return pulley fixed to the top fixed part of the hoistway. The separated braking device is mounted on at least one of car side suspension pulleys and a balance weight side suspension pulley or on both the car side suspension pulleys and the balance weight side suspension pulley.

Description

technical field [0001] The present invention relates to an elevator device, which comprises a traction machine divided into a driving device and a braking device, and the separated driving device and braking device are respectively installed in a hoistway. Background technique [0002] The traction machine of the existing elevator device has a driving device and a braking device together, and the driving device and the braking device are coaxially arranged side by side with the traction machine, and the braking device is arranged outside the driving device (for example, Refer to Patent Document 1). [0003] In addition, there is also an elevator apparatus in which a hoisting machine is installed in a lower portion of a hoistway (for example, refer to Patent Document 2). [0004] In addition, there is an elevator apparatus in which a hoisting machine is installed on the top of a hoistway (for example, refer to Patent Document 3). [0005] Patent Document 1: International Pu...
