[0004]
[Means for Solving the Problems]
In order to achieve the above object, claim 1 of the present application relates to a rotor in which a mounting beam is suspended between upper ends of a guide rail of an elevator car and a guide rail of a counterweight, and the stator is magnetically coupled to the mounting beam. A thin hoisting machine with an outer surface configured as a traction sheave is supported by suspension, and one end of the hoisting rope engaged with the thin hoisting machine supported by suspension is engaged with a turning pulley that supports a counterweight. The ends of the hoisting ropes are connected to the uppermost positions of the guide rails of the elevator car and the counterweight, and the other ends of the hoisting ropes are engaged with turning pulleys provided on both sides of the elevator car bottom. formed by connecting the top position of the guide rail of the guide rail and the counterweight of the elevator car to traverse the bottom of the elevator car Te structure It is obtained by the.
[0005]
According to the first aspect, since the thin hoisting machine is suspended and supported, the center of gravity of the thin hoisting machine is lowered, the stability is ensured, and the constituent materials can be reduced.
[0006]
That is, for example, when the hoisting machine device is arranged on a mounting base provided at an appropriate position in the elevator shaft or the like, the center of gravity of the hoisting machine device is above the mounting base, so that it is prevented from falling over. In addition, various materials are necessary for stable support.
[0007]
Furthermore, the motor is configured such that the outer peripheral surface of the rotor in which the thin hoisting machine is magnetically coupled to the stator is configured as a traction sheave. That is, the configuration is such that the rotor traction sheave of the motor is immediate. Therefore, the hoisting machine can be reduced in thickness and size and space can be saved, and the suspension support, which is a feature of the present invention, becomes extremely easy.
[0008]
Further, a mounting beam is suspended between the upper end of the guide rail of the elevator car and the guide rail of the counterweight, and the thin hoisting machine is suspended and supported on the mounting beam. Therefore, for example, the suspension state of the thin hoisting machine can be stabilized as compared with a case where a single guide rail or a wall surface of an elevator shaft, or a suspension bracket or the like is provided between them to support suspension, Furthermore, the rail itself can be stabilized.
[0009]
Furthermore, one end of the hoisting rope engaged with the thin hoisting machine supported by suspension is engaged with a turning pulley that supports the counterweight, and the tip thereof is the guide rail of the elevator car and the guide rail of the counterweight. The other end of the hoisting rope is engaged with turning pulleys provided on both sides of the bottom of the elevator car so as to cross the bottom of the elevator car and the guide rail and counterweight of the elevator car Connected to the uppermost position of the guide rail. Therefore, a so-called machine roomless elevator can be provided by directly applying an elevator car and a safety device frame of an elevator equipped with a conventional mechanical device.
[0010]
According to a second aspect of the present invention, an anti-vibration material is interposed between the guide rail of the elevator car , the upper end of the guide rail of the counterweight, and the mounting beam. According to the second aspect , a structure for vibration proofing, sound proofing, and vibration proofing can be easily obtained.
[0011]
According to a third aspect of the present invention, a vibration isolator is interposed between the mounting beam and the suspension bracket of the thin hoisting machine. According to the third aspect , similarly to the second aspect , it is possible to easily obtain a structure for vibration proofing, soundproofing, and quakeproofing.
[0012]
Claim 4 is an elevator apparatus according to claim 3 in which is interposed a vibration damping material between the guide rail upper and mounting beam of the guide rail and the counterweight of the elevator car. That is, the are a in claim 2 and 3 that is interposed an anti-vibration member at two locations of the description, it is possible to further improve vibration damping, soundproofing, the BoShin effect.
