Definitions

  • the present invention relates to an elevator apparatus in which a driving machine and a control device are arranged in a machine room.
  • Fig. 9 is a plan view showing an example of a machine room of a conventional elevator apparatus
  • Fig. 10 is a sectional view of the machine room in Fig. 9.
  • a machine room 2 is arranged above a hoistway 1 in which a car (not shown) is raised and lowered.
  • the machine room 2 includes a floor surface 3, a side wall 4, and a ceiling 5.
  • the side wall 4 is provided with a doorway 4a.
  • a driving machine (hoisting machine) 6 for raising and lowering the car and a control device (control panel) 7 for controlling the driving machine 6 are arranged on the floor surface 3.
  • the driving machine 6 is arranged such that a working space for maintenance inspection is secured in the periphery thereof.
  • the control device 7 has a front door 7a, and is arranged such that maintenance inspection work for the control device 7 is performed with the front door 7a being opened.
  • the present invention has been made in view of the above, and therefore has an object to obtain an elevator apparatus in which space can be saved in a machine room.
  • an elevator apparatus including: a machine room having a floor surface; a driving machine for raising and lowering the car, arranged in the machine room; and a control device for controlling the driving machine, arranged in the machine room, in which: the floor surface of the machine room; is provided with a concave portion and the control device is received in the concave portion.
  • Fig. 1 is a plan view showing an inner part of a machine room in an elevator apparatus in accordance with Embodiment 1 of the present invention
  • Fig. 2 is a sectional view of the machine room in Fig. 1.
  • a machine room 12 is arranged above a hoistway 11 in which a car (not shown) is raised and lowered.
  • the machine room 12 has a floor surface 13, a side wall 14, and a ceiling 15.
  • the side wall 14 is provided with a doorway 14a.
  • a driving machine (hoisting machine) 6 for raising and lowering the car is arranged on the floor surface 13.
  • the floor surface 13 is provided with a concave portion 16.
  • the concave portion 16 has a bottom surface 16a and an opening portion 16b that faces the bottom surface 16a.
  • the concave portion 16 is provided with a flat lid 17 for opening and closing the opening portion 16a.
  • Fig. 1 shows a state where the lid 17 is closed
  • Fig. 2 shows a state where the lid 17 is opened.
  • the lid 17 constitutes a flat surface continuous with the floor surface 13 in the state where the concave portion 16 is closed.
  • an operator can step on the lid 17, and a space above the lid 17 serves as a movement space or working space at the time of the maintenance inspection work for the driving machine 6.
  • a control device (control panel) 18 for controlling the driving machine 6 and other devices is received in the concave portion 16.
  • the control device 18 is received in the concave portion 16 in such fashion as to enable the maintenance inspection thereof to be performed by only opening the lid 17 without the control device 18 being removed from the concave portion 16. That is, the control device 18 is placed on the bottom surface 16a such that a front surface of the control device 18 faces upward.
  • an installation space of the control device 18 also serves as the movement space or working space at the time of the maintenance inspection work for the driving machine 6. Therefore, space can be saved in the machine room 12.
  • the maintenance inspection work for the control device 18 can be easily performed by only opening the lid 17.
  • the lid 17 for opening and closing the opening portion 16b of the concave portion 16 is provided, and thus, a sufficient strength of the lid 17 as a part of a floor for the movement space or working space can be secured without changing the strength of the control device 18. Accordingly, the control device 18 can be protected.
  • the opening portion 16b is opened / closed by one lid in Embodiment 1, but may be opened / closed partially by plural lids. In such a case, each of the lids is light in weight to enable opening / closing operations to be carried out with ease.
  • the lid 17 which is opened / closed through pivotal movement is shown in Embodiment 1.
  • the lid may be provided with a handle gripped by an operator at the time of opening / closing.
  • the handle may be temporarily attached to the lid at the time of opening / closing.
  • the surface of the lid can be kept flat except at the time of opening / closing.
  • the handle cannot be an obstacle to the movement or work made by the operator.
  • the lid 17 which is opened / closed through manual operation is shown in Embodiment 1; however, there may be adopted a lid that is driven by an electric motor or the like to be opened / closed.
  • the lid may be provided with a transparent window, or the whole lid may be formed of a transparent material. This enables visual inspection of the control device 18 to be carried out with the lid being closed.
  • the lid may be provided with an air hole.
  • the air hole may be provided with a fan device.
  • control device 18 is placed on the bottom surface 16a in Embodiment 1.
  • control device may be mounted on a back surface of the lid in the case where the control device is light in weight.
  • Fig. 3 is a plan view showing an inner part of a machine room in an elevator apparatus in accordance with Embodiment 2 of the present invention
  • Fig. 4 is a sectional view of the machine room in Fig. 3.
  • Figs. 3 and 4 show a state where the lid 17 is opened.
  • a control device (control panel) 19 for controlling the driving machine 6 and other devices is received in the concave portion 16.
  • the control device 19 includes a control device main body 19a, which is placed on the bottom surface 16a, and a divided portion 19b, which is mounted on the back surface of the lid 17.
  • Other structures in Embodiment 2 are the same as those in Embodiment 1.
  • an installation space of the control device 19 also serves as the movement space or working space at the time of the maintenance inspection work for the driving machine 6. Therefore, space can be saved in the machine room 12.
  • the divided portion 19b is mounted on the back surface of the lid 17, and thus, the area of the control device 19, which is exposed when the lid 17 is opened, is expanded. That is, the arrangement area of the control device, which can be subjected to maintenance inspection, becomes approximately twice as large as the area in the case where the divided portion 19b is not mounted on the lid 17. Therefore, working performance of the maintenance inspection work for the control device 19 can be improved.
  • Fig. 5 is a plan view showing an inner part of a machine room in an elevator apparatus in accordance with Embodiment 3 of the present invention
  • Fig. 6 is a sectional view of the machine room in Fig. 5.
  • a control device (control panel) 20 for controlling the driving machine 6 and other devices is received in the concave portion 16.
  • the control device 20 is divided into first and second division units 21 and 22.
  • Each of the division units 21 and 22 can be independently removed from the concave portion 16.
  • each of the division units 21 and 22 is structured to have a weight at which an operator can carry the unit.
  • first and second division units 21 and 22 have casings 21a and 22a, respectively.
  • the casings 21a and 22a have casing upper surfaces 21b and 22b, which constitute flat surfaces continuous with the floor surface 13, respectively.
  • An operator can step on the casing upper surfaces 21b and 22b, and the casing upper surfaces 21b and 22b each serve as the movement space or working space at the time of the maintenance inspection work for the driving machine 6.
  • the casing upper surfaces 21b and 22b are provided with handles 21c and 22c, respectively.
