Description

  Embodiments described herein relate generally to a gantry and an elevator apparatus.

  A gearless motor that is quiet and consumes little energy is used as a hoisting machine in the elevator apparatus. The hoisting machine and the control device are generally arranged in a machine room provided above the hoistway. However, in recent years, with the miniaturization of motors and the like, elevator apparatuses without a machine room have come to appear. In this type of elevator apparatus, a motor is disposed inside the hoistway. Therefore, it is necessary to take measures to prevent noise from the motor from being transmitted to the elevator cab.

  The noise from the motor may be caused by resonance caused when the frequency of the motor body matches the natural frequency of the casing constituting the motor. This kind of noise can be suppressed to some extent, for example, by improving the rigidity of the casing. However, even if the rigidity of the casing is improved, noise generated by the rotation of the rotor of the motor is transmitted to the outside of the cab or the hoistway.

The car 31 is disposed between the guide rails 21 and 22 and is attached to the guide rails 21 and 22 so as to be movable in the vertical direction. On the surface of the car 31 on the −Y side, a door (not shown) for entering and exiting the internal space is provided.

  The counterweight 32 is attached to the guide rails 22 and 23 so as to be movable in the vertical direction. The weight of the counterweight 32 is adjusted to be a predetermined ratio with respect to the weight of the car 31.

  The elevating motor 40 is a motor for elevating the car 31. The elevating motor 40 is disposed above the hoistway 100 so that the rotation axis is parallel to the Y axis. The lifting motor 40 is supported by a gantry 50.

  FIG. 2 is an exploded perspective view of the lifting motor 40 and the gantry 50. The elevating motor 40 has a rotation shaft 41a whose longitudinal direction is the Y-axis direction and a drive unit 41 for rotating the rotation shaft 41a. The rotating shaft 41a is a columnar member, and a pulley 42 is fixed to the −Y side end. The drive unit 41 includes a rotor, a stator, and a housing that accommodates these.

  FIG. 3 is an exploded perspective view of the gantry 50. As shown in FIG. 3, the gantry 50 includes a base member 51, a set of side plates 52, a support member 53, and a sound absorbing material 530.

  The base member 51 is a plate-like member whose longitudinal direction is the Y-axis direction. The base member 51 is made of a metal such as iron and has a thickness of about 25 mm.

  The side plate 52 is a plate-like member whose longitudinal direction is the Y-axis direction. The side plate 52 is shaped so that the size in the Y-axis direction is slightly shorter than that of the base member 51. The side plate 52 has a sound-absorbing sheet 520 attached to surfaces facing each other. The sound absorbing sheet 520 is made of, for example, foamed urethane or glass wool.

  The support member 53 is a frame-shaped member having a longitudinal direction in the Y-axis direction and a rectangular opening 53a formed in the center. The length of the support member 53 in the Y-axis direction is substantially equal to the length of the side plate 52. The support member 53 is composed of four rod-shaped members 54 to 57 made of a metal such as iron. The rod-shaped members 54 and 55 are members whose longitudinal direction is the Y-axis direction. The rod-shaped members 56 and 57 are members whose longitudinal direction is the X-axis direction. The lengths of the rod-shaped members 54 and 55 are equal to the length of the side plate 52.

  The rod-shaped members 54 to 57 are welded at both ends of the rod-shaped member 56 to + Y side end portions of the rod-shaped members 54 and 55, and both ends of the rod-shaped member 57 are bonded to −Y side end portions of the rod-shaped members 54 and 55. It is integrated by welding.

  The sound absorbing material 530 is a plate-like member whose longitudinal direction is the Y-axis direction. The sound absorbing material 530 is made of, for example, foamed urethane or glass wool. The sound absorbing material 530 is shaped to have the same size as the opening 53 a formed in the support member 53.

  The base member 51, the side plate 52, the support member 53, and the sound absorbing material 530 are integrated by welding the support member 53 to the upper surface of the base member 51 and welding the side plate 52 along the outer edge of the upper surface of the base member 51. . Then, the sound absorbing sheet 520 is bonded to the side plate 52, and the sound absorbing material 530 is disposed inside the opening 53a of the supporting member 53, whereby the gantry 50 shown in FIG. 2 is completed. As shown in FIG. 1, the gantry 50 is supported by a support material (not shown) so that the longitudinal direction is parallel to the Y axis.

  When the elevating motor 40 is placed on the gantry 50, for example, as can be seen with reference to FIG. 2, the elevating motor 40 is lifted by a crane or the like, so Take it down. And the raising / lowering motor 40 is fixed with respect to the supporting member 53 with a volt | bolt etc., for example. Thereby, as shown in FIG. 4, the lifting motor 40 is attached to the gantry 50.

  When the elevating motor 40 is attached to the gantry 50, the pulley 42 attached to the rotating shaft 41a of the elevating motor 40 protrudes from the gantry 50 in the -Y direction, the sound absorbing material 530 faces the lower surface of the elevating motor 40, and The sound absorbing sheet 520 faces the side surface of the lifting motor 40.

  As shown in FIG. 1, a wire 60 is wound around the pulley 42 of the lifting motor 40. The wire 60 has one end fixed to the car 31 and the other end fixed to the counterweight 32.

  The control panel 70 accommodates a lifting motor 40 and a control device for controlling equipment provided in the car 31. When the control device rotates the elevating motor 40 in the normal direction, the car 31 is raised and the counterweight is lowered. When the control device reverses the lifting motor 40, the car 31 is lowered and the counterweight is raised.

  As described above, in the elevator apparatus 10 according to the present embodiment, the lower surface of the lifting motor 40 placed on the gantry 50 faces the sound absorbing material 530 disposed on the upper surface of the base member 51, and the side surface of the lifting motor 40. Is opposed to the sound absorbing sheet 520 affixed to the side plate 52. For this reason, the noise generated from the lifting motor 40 and propagated in the horizontal direction or downward is attenuated by the sound absorbing material 530 and the sound absorbing sheet 520. For this reason, the noise transmitted to the inside of the car 31 is reduced.

  In the present embodiment, a support member 53 that supports the lifting motor 40 is separately provided on the upper surface of the base member 51. Since the base member 51 is reinforced by the support member 53, the base member 51 can be thinned.

  As mentioned above, although embodiment of this invention was described, this invention is not limited by the said embodiment. For example, in the above embodiment, the side plate 52 is welded to the base member 51. Not limited to this, the base member 51 and the side plate 52 may be integrally formed.

  In the above-described embodiment, the case where the support member 53 includes the four rod-shaped members 54 to 57 made of metal has been described. The support member 53 is not limited to this, and may be integrally formed from one material.

  In the above embodiment, the case where the sound absorbing material 530 and the sound absorbing sheet 520 are foamed urethane or glass wool has been described. The material of the sound absorbing material 530 is not limited to this. The frequency of noise generated from the lifting motor 40 is approximately 600 Hz. Therefore, a material that efficiently absorbs 600 Hz noise can be selected and used. This kind of material may be a composite material composed of a plurality of materials such as foamed urethane and glass wool.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
