Definitions

  • This disclosure relates to a lifting device.
  • Patent Document 1 discloses a device that moves on a vertically installed rope, although it is not intended for installation in an elevator. Two sets of wheels are arranged above and below, sandwiching the rope from three directions at the same height, for a total of six wheels that move on the rope. When attaching this device to a rope, part of the casing is removed, the rope is inserted from the side, and part of the casing is closed. Furthermore, in order to press the wheels against the rope, it is necessary to adjust the length of the shaft that secures the wheels to the casing with a nut. As such, installing this device is time-consuming.
  • the piano wire 4 serves as a reference for the horizontal position when installing rails or doors that guide the car.
  • an elevator installation robot 5 is attached to one piano wire 4.
  • the elevator installation robot 5 performs various tasks while moving up and down by itself, i.e., ascending and descending.
  • Figure 10 is a top view showing the relationship between the piano wire 4 and the drive wheels 11 when there are three drive wheels 11.
  • the drive wheels 11 are arranged at 120° intervals with respect to the piano wire 4.
  • Three of each of the upper plate support parts 14, self-multiplying links 12, and angle interlocking links 15 are required.
  • the other members are the same as those described above.
  • the contact area between the piano wire 4 and the drive wheels 11 can be increased, and the load on the piano wire 4 and the drive wheels 11 can be reduced.
  • the allowable weight of the elevator installation robot 5 can be increased.
  • the drive wheels 11 are moved toward the piano wire 4 from three directions, there is an advantage that the piano wire 4 can be grasped more easily than when there are two drive wheels 11.
  • the center of gravity of the machine body 7 is preferably below the drive wheels 11 and on or near the piano wire 4. Having the center of gravity in this position reduces the possibility of losing balance while traveling or working.
  • the work unit 51 is composed of a laser sensor, a work unit control unit 56, etc., and measures the shape or dimensions of the elevator shaft 1.
  • a plate 58 to which a LiDAR as a laser sensor and a work unit control unit 56 are fixed is fixed on the top plate 13 or under the bottom plate 19 of the elevator installation robot 5.
  • the work unit control unit 56 is connected to the control unit or battery of the elevator installation robot 5, and obtains height information or power of the elevator installation robot 5.
  • the shape and dimensions of the elevator shaft 1 can be obtained with high accuracy.
  • information on the entire elevator shaft 1 can be obtained with high accuracy, so difficult points in equipment installation due to dimensions can be identified and countermeasures can be considered in advance.
