Definitions

  • the present invention relates to a braking device for elevator traction machine which is used in a machine-room-less elevator.
  • an elevator traction machine In conventional elevators, an elevator traction machine is installed in a machine room and, therefore, a braking device is fixed with respect to a traction machine main body (a housing such as a gear case).
  • a braking device for an elevator traction machine has been adopted as it is also in an elevator traction machine used in machine-room-less elevators.
  • a braking device is fixed with respect to a traction machine main body.
  • a brake In a braking device for elevator traction machine used in a conventional machine-room-less elevator, a brake is fixed with respect to a traction machine main body. Therefore, in such a brake mechanism the characteristics of which change due to gravity, elevator traction machines in which a braking device is fixed had to be provided separately to suit a case where the installation position of a traction machine is in an upper part of the interior of the hoistway or in a lower part of the interior of the hoistway where the installation of a traction machine is reversed in order to ensure that the installation position of a traction machine facilitates the adjustment of the brake. Therefore, this caused a cost rise.
  • the present invention has been made to solve such conventional problems and has as its object the provision of a braking device for elevator traction machine which has a construction that makes the braking device removable from a traction machine main body and makes a mounting portion of the braking device rotatable in increments of 90 degrees with respect to a rotary shaft, whereby an installation position of the traction machine can be set in such a manner as to facilitate the adjustment of the brake.
  • a mounting portion of a braking device for elevator traction machine which is attached to a rotary shaft of an elevator traction machine is attached rotatably with respect to the rotary shaft of the traction machine so that an installation position of the braking device can be changed.
  • the mounting portion of the braking device is attached rotatably in increments of 90 degrees with respect to the rotary shaft of the traction machine so that the installation position of the braking device can be changed in increments of 90 degrees.
  • the braking device has a brake mechanism the characteristics of which change due to gravity.
  • the brake can be installed always in a specific direction regardless of the installation in an upper part of the interior of the hoistway or in a lower part where the installation of a traction machine is reversed. Therefore, it is possible to keep the method of setting the brake, setting conditions and the like uniform by the installation of the traction machine.
  • Figure 1 is a front view of a braking device for elevator traction machine, which is installed in a lower part of the hoistway , in a first embodiment of the present invention.
  • Figure 2 is an exploded perspective view of a braking device for elevator traction machine in the first embodiment of the present invention.
  • Figure 3 is a front view of a braking device for elevator traction machine in the first embodiment of the present invention.
  • Figure 4 is a front view of a lower part of the hoistway where a braking device for elevator traction machine of the present invention can be changed to a height that facilitates maintenance according to the mounting position of the traction machine.
  • Figure 5 is a front view of a braking device for elevator traction machine of the present invention, which is installed in an upper part of the hoistway.
  • a traction machine 2 is installed in a lower part of the interior of a hoistway 1 of the elevator.
  • a braking device 4 is attached to a rotary shaft 3 of the traction machine 2. As shown in Figure 2, this braking device 4 is an independent part separate from a motor portion 5 of the traction machine 2.
  • the motor portion 5 of the traction machine 2 and the braking device 4 are each a rectangular frame, and each of the frames has four attaching holes 6 at the corners thereof. Because as shown in Figure 3, the longitudinal pitch a and the lateral pitch a between the holes 6 are set equal to each other, the braking device 4 is attached rotatably in increments of 90 degrees with respect to the rotary shaft 3 so that the installation position of the braking device 4 can be changed.
  • the braking device 4 is constituted by an electromagnetic magnet 7, an armature 8, a brake arm 9, a fulcrum pin 10 provided in a bottom end part of this brake arm 9, a brake spring 11, a braking piece 12, etc.
  • a brake drum 13 disposed opposite to the braking piece 12 of the braking device 4 and other parts are provided.
  • reference numeral 14 denotes an elevator car.
  • the direction of the braking device 4 can be changed by the position of the installation height of the traction machine 2 and, therefore, it is possible to freely bring the adjustment position A of the brake to a height that facilitates the maintenance of the brake.
  • the fulcrum pin 10 is arranged in the lower part of the interior of the hoistway when the braking device is installed in this lower part shown in Figure 1 and the fulcrum pin 10 is arranged in the upper part of the interior of the hoistway when the braking device is installed in this upper part shown in Figure 5, whereby it is possible to install the braking device 4 in one direction regardless of whether the installation position of the traction machine 2 is in the upper or lower part of the hoistway and hence mistakes during maintenance can be minimized by making the setting standard uniform.
  • Figure 6 is a front view of a braking device for elevator traction machine in a second embodiment of the present invention.
  • the motor portion 5 of the traction machine 2 and the braking device 4 are each a rectangular frame, and each of the frames has four attaching holes 6 at the corners thereof.
  • the motor portion 5 of the traction machine 2 and the braking device 4 are each a circular frame and provided with four attaching holes 6 at equal intervals of 90 degrees.
  • the longitudinal pitch a and the lateral pitch a between the holes 6 are set equal to each other, the braking device 4 is attached rotatably in increments of 90 degrees with respect to the rotary shaft 3 so that the installation position of the braking device 4 can be changed.
  • the braking device for elevator traction machine As described above, in the braking device for elevator traction machine according to the present invention, as a braking device for elevator traction machine used in a machine-room-less elevator, it is possible to set the installation position of the traction machine in such a manner as to facilitate the adjustment of the brake by ensuring that the mounting portion of the braking device is attached rotatably in increments of, for example, 90 degrees with respect to the rotary shaft of the traction machine. Also, in the case of a brake mechanism the characteristics of which change due to gravity, it is possible to always install the brake in a specific direction regardless of the installation in an upper part of the interior of the hoistway or in a lower part where the installation of a traction machine is reversed. Therefore, it is possible to keep the method of setting the brake, setting conditions and the like by the installation of the traction machine.
