Definitions

  • the present invention relates to an elevator.
  • Patent Literature 1 discloses an elevator device, which comprises a brake pad of a disc brake system which has one linear groove formed to extend through substantially the center of the brake pad, and two other linear grooves formed to be perpendicular to the one linear groove and face each other with the center therebetween at positions away from the center, and that either of the one linear groove and the two linear grooves is formed along a sliding contact direction of the brake pad and a brake disc.
  • Patent Literature 4 discloses an elevator braking device, which includes a rotating body and three or more independent braking devices.
  • Figure 1 is a front view illustrating a hoisting machine for elevator device according to one example of the present invention.
  • the hoisting machine for elevator device is installed on a machine base 1 and a drive motor (not illustrated) which is supported by a motor frame 2, a sheave 3 which is coupled to a rotary shaft of the drive motor, a brake disk 4 which is larger than the sheave 3 in diameter are coaxially arranged on the machine base 1.
  • Three disk brakes 5A, 5B, 5C are attached to the motor frame 2 respectively.
  • a main rope 6 which is coupled to a car (not illustrated) is wound on the sheave 3 and is stretched over a deflector wheel 7 which is attached to a support frame on which the machine base 1 is placed. Accordingly, the main rope 6 which is wound on the sheave 3 is inclined on the side where the deflector wheel is provided and, on the other hand, hangs down vertically on the other.
  • the respective disk brakes 5A, 5B, 5C are the same as one another in configuration and have generally known structures and therefore detailed description thereof is omitted.
  • the respective disk brakes 5A, 5B, 5C are configured in such a manner that after cutting off electric conduction to the drive motor, the disk brakes 5A, 5B, 5c are brought into non-excited states, brake shoes are pressed against both surfaces of the brake disk 4 with spring force so as to apply braking force to the brake disk 4.
  • the disk brake 5A which is arranged on the deflector wheel 7 side and the disk brake 5B which is arranged on an intermediate part are arranged at the almost same level avoiding the top part which is located on the uppermost part of the brake disk 4.
  • the disk brake 5C which is arranged on the opposite side of the deflector wheel 7 is arranged adjacent to the disk brake 5A or 5B. Accordingly, when virtualizing a vertical line which passes through the center line of a rotary shaft of the sheave 3, the three disk brakes 5A, 5B, 5C are arranged avoiding this virtual vertical line and are asymmetrically arranged.
  • the deflector wheel 7 is arranged on the disk brake 5A side and a case where it is arranged on the disk brake 5B side depending on the shape of a hoistway and so forth.
  • the deflector wheel 7 is arranged on the disk brake 5A side and the disk brake 5C is arranged in the form of being adjacent to the other disk brake 5B.
  • the disk brake 5C is arranged next to the disk brake 5A depending on the arrangement of the deflector wheel 7, it is preferable to perform processing on or to attach a device to the motor frame 2 for attachment of the disk brake 5C next to the disk brake 5A. By configuring in this way it is possible to easily cope with either arrangement of the deflector wheel simply by changing an attachment position of the disk brake 5c.
  • FIG. 1 is a front view illustrating a state where the disk brake 5B is opened at the time of maintenance.
  • the disk brake 5B is attached to the motor frame 2 with a plurality of support pins 8 similarly to the other disk brakes 5A, 5C.
  • work is performed by removing one of the support pins and rotating it around the remaining support pin 8 as illustrated in the drawing.
  • part of the disk brake 5B reaches a maximum height which is a height H2 in the illustrated state.
  • Figure 4 is a side view of the hoisting machine for elevator device according to one example.
  • the sheave 3 and the disk brake 5 are in a relation that they overlap each other when viewing from the side.
  • the disk brake 5 is configured such that an axial length of the disc brake protrudes to an upper part of the sheave 3 in the axial direction, and overlaps the sheave 3 in a radial direction of the sheave 3.
  • the disk brake 5C when, in a case where the main rope 6 which is wound on the sheave 3 obliquely falls by the deflector wheel 7, the disk brake 5C is arranged on the lateral of the hoisting machine on the side that the deflector wheel 7 is present, the main rope 6 interferes with the disk brake 5C. Accordingly, the interference thereof with the main rope 6 can be prevented by arranging the disk brake 5C on the oppose side of the deflector wheel 7.
  • FIG. 5 is a front view of the hoisting machine for elevator device according to one example.
  • a rope guard 10 which is not illustrated in Figure 1 is connected to a pedestal 9 and is arranged between the disk brake 5B and the disk brake 5C.
  • This rope guard 10 is arranged on the side that the disk brake 5C is present, that is, on the opposite side of the deflector wheel 7. It is desirable that the position of the rope guard 10 be above a central axis of the sheave 3 and it be provided upward within 45 degrees with a horizontal-position height of the central axis of the sheave 3 set as 0 degree.
  • This rope guard is a component which prevents the main rope 6 from getting out of a sheave groove when shaking in an earthquake.
  • Figure 6 is a front view of the hoisting machine for elevator device in a case where the deflector wheel is placed on the side which is opposite to that in Figure 5 .
  • the disk brake 5C is arranged on the side of the motor frame 2 that the deflector wheel 7 is not arranged, and the rope guard is connected to the pedestal 9 and is arranged on the side that the deflector wheel 7 is not arranged and between the disk brake 5A and the disk brake 5C.
  • the present invention is not limited to the above-described example and various modified examples are included.
  • the above-described example is described in detail for explaining the present invention intelligibly and is not necessarily limited to the one which is equipped with all the configurations that are described.
