Abstract
Description
- The present invention relates to an elevator system, and more particularly, to an elevator system in which a main cable connecting a car to a counterweight is driven by a hoisting machine disposed on top of the car.
- FIGS. 22 and 23 show a conventional elevator system described in; for example, Japanese Patent Application Laid-Open No. Hei-10-114481, wherein FIG. 22 is a conceptual longitudinal cross-sectional view, and FIG. 23 is an enlarged view showing a portion "A" shown in FIG. 22. In the drawings,
reference numeral 1 designates a shaft; and 2 designates a car which travels vertically along a predetermined path within theshaft 1. Aservice recess 3 is formed in a lower portion of thecar 2, and an access door 4 is formed in an upper surface of theservice recess 3. Aseat plate 5 equipped with a cushion is removably provided on theservice recess 3 so as to cover the access door 4.Reference numeral 6 designates a hoisting machine disposed on the bottom of theshaft 1 so as to correspond to the position of theservice recess 3. The hoistingmachine 6 moves thecar 2 vertically by way of acable 7. - In the conventional elevator system of the above-described configuration, the hoisting
machine 6 is energized to move thecar 2 vertically along a predetermined path within theshaft 1 by way of thecable 7. Theseat plate 5 is removed while thecar 2 is situated at its lowermost position, and in the car 2 a service engineer conducts an inspection of and performs maintenance of the hoistingmachine 6 by way of the access door 4. - FIG. 24 is a longitudinal cross-sectional view conceptually showing another conventional elevator system described in, for example, Japanese Utility Model Publication No. Hei-3-48142. In the drawing,
reference numeral 1 designates a shaft; 2 designates a car which travels vertically along a predetermined path within theshaft 1; and 6 designates a traction machine. Thetraction machine 6 is disposed on the lower surface of an upper beam of thecar 2, along with asheave 8 whose rotor axis is oriented in the horizontal direction. -
Reference numeral 9 designates a counterweight which is moved vertically along another predetermined path within theshaft 1; and 10 designates a counterweight pulley provided on thecounterweight 9.Reference numeral 11 designates a top pulley which is rotatively fixed to the top of theshaft 1 and whose rotor axis is oriented horizontally; and 12 designates a main cable. One end of themain cable 12 is connected to the upper end of theshaft 1 by means of ananchor 13, and the other end of themain cable 12 is connected to the upper end of theshaft 1 by means of anotheranchor 14. Themain cable 12 is wound around thecounterweight pulley 10, thetop pulley 11, and thesheave 8, in the sequence given. - In the conventional elevator system of the foregoing configuration, when the hoisting
machine 6 is energized, thesheave 8 is rotated, to thereby move thecar 2 and thecounterweight 9 in opposite directions by way of themain cable 12. Since the hoistingmachine 6 is mounted on thecar 2, a machinery room, which would otherwise be independently provided at a position above theshaft 1, is omitted, thus reducing the space occupied by the elevator system within an un-illustrated building. - In the conventional elevator system shown in FIGS. 22 and 23, a service engineer conducts an inspection of and performs maintenance of the hoisting
machine 6 in thecar 2 while stooping over the hoistingmachine 6. Such a stooped posture deteriorates the ability of the service engineer to work. Further, the service engineer must pay careful attention so as to avoid accidentally dropping a tool or a like instrument down into theshaft 1, thus deteriorating the effectiveness of maintenance. In the event of the lower portion of theshaft 1 being flooded, the hoistingmachine 6 may be damaged by water. - Alternatively, in the conventional elevator system shown in FIG. 24, the
hoisting machine 6 is disposed at an elevated position with reference to thecar 2. The service engineer squeezes into and bends his body within a narrow space formed between the roof of thecar 2 and the hoistingmachine 6 and conducts an inspection of and performs maintenance of the hoistingmachine 6. Such an unnatural posture deteriorates the effectiveness of maintenance. Further, the service engineer must pay careful attention so as to avoid accidentally dropping a tool or a like instrument in theshaft 1, thus deteriorating the effectiveness of maintenance. - The present invention has been conceived to solve a problem in the conventional elevator systems as described above, and the object of the present invention is to provide an elevator system which includes a car having a hoisting machine provided thereon and enables a service engineer to readily perform maintenance of the hoisting machine.
- According to one aspect of the present invention, an elevator system comprises a car which travels vertically along a predetermined path within a shaft. A counterweight is provided which travels vertically along another predetermined path within the shaft, and the counterweight has a pulley mounted thereon. A hoisting machine including a sheave is provided on the exterior side surface of the car, and the rotor axis of said sheave is oriented horizontally. A top pulley is rotatively mounted on the upper end of the shaft with the rotor axis thereof oriented horizontally. A main cable is connected to the upper end of the shaft at both ends thereof respectively, and the main cableis wound around said pulley mounted on the counterweight, the top pulley, and the sheave. Further, an access port is provided on the side surface of the car corresponding to the hoisting machine to be subjected to maintenance.

As a result, the portion of thecar 2 close to its center of gravity is suspended, thereby diminishing an offset load exerted on thecar 2 and an offset load exerted on a rail for guiding thecar 2. Consequently, the structure of the elevator system can be simplified, and cost required for constructing the elevator system can be decreased. - FIGS. 9 and 10 show an elevator system according to a fifth embodiment of the present invention. FIG. 9 is a conceptual transverse plan view showing an elevator system, and FIG. 10 is a longitudinal cross-sectional view conceptually showing the suspended state of the main cable of the elevator system shown in FIG. 9. The remaining portions of the elevator system of the present embodiment other than that portion illustrated in FIGS. 9 and 10 are constructed in the same manner as shown in FIGS. 1 through 4.
- In the drawings, those reference numerals, which are the same as those provided in FIGS. 1 through 4, FIGS. 6 and 7, designate corresponding elements.

Thefirst side pulley 35 is disposed in a lower portion of thesidewall 30 so as to correspond to thedeflector wheel 31 disposed on the deep-inside wall 16.Reference numeral 36 designates a second side pulley which is rotatively mounted on thesidewall 30 and is disposed at a position closer to theentrance door 15 than is thefirst side pulley 35. -
Reference numeral 12 designates a main cable. One end of themain cable 12 is attached to the upper end of theshaft 1 by means of theanchor 13, and the other end of themain cable 12 is attached to the upper end of theshaft 1 at a position corresponding to the location of thesecond side pulley 36, by means of anotheranchor 14. Themain cable 12 is wound around thecounterweight pulley 10, thetop pulley 11, the rear-end suspension position 34 on thesheave 25, thedeflector wheel 31, thefirst side pulley 35, and thesecond side pulley 36, in the sequence given. - In the elevator system of the foregoing configuration, the hoisting
machine 6 is disposed on the exterior side surface of thecar 2, and the maintenance means 19 is provided on the wall surface of thecar 2. Accordingly, although not described in detail, the elevator system of the fifth embodiment shown in FIGS. 9 and 10 yields the same working-effect as that yielded in the embodiment shown in FIGS. 1 through 4. - In the fifth embodiment shown in FIGS. 9 and 10, the
car 2 is suspended by themain cable 12 by way of thefirst side pulley 35 and thesecond side pulley 36. Theanchor 14 suspends the front side of thecar 2, and the rear portion of thecar 2 is suspended by themain cable 12 at the rear-end suspension position 34. More specifically, thecar 2 is suspended by themain cable 12 at the rear-end suspension position 34 formed on thedeflector wheel 31, as well as at the position on the lower surface of thecar 2 which is spaced apart from the rear-end suspension position 34 in a diagonal direction. As a result, the portion of thecar 2 close to its center of gravity is suspended, thereby diminishing an offset load exerted on thecar 2 and an offset load exerted on a rail for guiding thecar 2. Consequently, the structure of the elevator system can be simplified, and cost required for constructing the elevator system can be decreased. - Since the lower ends of the respective first and second side pulleys 35 and 36 are located at a position higher than the lower surface of the
car 2, the pit of theshaft 1 can be made shallow. Further, a margin for elevation of thecar 2, which is ensured in the upper portion of theshaft 1, can be made small. In other words, an upper margin space originating from the highest stopping position of thecar 2 within theshaft 1 or a lower margin space originating from the lowest stopping position of thecar 2 can be diminished, thus shortening the overall length of theshaft 1. Accordingly, cost incurred for constructing theshaft 1 and installing the elevator system in theshaft 1 can be reduced. In the fifth embodiment, it is obvious that the same working-effect can be yielded even when the positions of the hoistingmachine 6 and thedeflector wheel 31 are switched. - FIG. 11 is a conceptual transverse plan view showing an elevator system according to a sixth embodiment of the present invention.

upper pulley 40 and the secondupper pulley 41 are mounted on the roof of thecar 2, the pit of theshaft 1 can be made shallow. Accordingly, cost incurred for constructing theshaft 1 and installing the elevator system in theshaft 1 can be reduced. - The features and the effects of the present invention as described above may be summarized as follows.
- According to one aspect of the present invention, in an elevator system, a car travels vertically along a predetermined path within a shaft. A counterweight which is moved vertically along another predetermined path within the shaft. A hoisting machine is constituted to assume a shallow depth dimension, and is provided on the exterior side surface of the car. A top pulley is rotatively mounted on the upper end of the shaft, and whose rotor axis is oriented horizontally. A main cable is connected to the upper end of the shaft at both ends, and is wound around a pulley mounted on the counterweight, the top pulley, and the hoisting machine, in this sequence. A sheave constitutes the principal section of the hoisting machine, and has the main cable wound therearound, and whose rotor axis is oriented horizontally. Further, maintenance means including an access port is provided on the side surface of the car, and is opened so as to correspond to a portion of the hoisting machine to be subjected to maintenance.
- Therefore, the hoisting machine is disposed on the exterior side surface of the car, and the maintenance means is provided on the wall of the car. In the car, a service engineer opens the door of the maintenance means and conducts an inspection of and performs maintenance on the hoisting machine by way of an access port. Thus, the service engineer does not need to stoop to inspect the hoisting machine and can perform operation while in a natural posture. Further, the service engineer is not required to pay special attention so as to avoid accidentally dropping a tool or a like instrument into the shaft, thereby improving the efficiency of maintenance. Further, since the hoisting machine is disposed on the exterior side surface of the car, there can be prevented damage to the hoisting machine, which would otherwise be caused when the lower portion of the shaft is flooded.
- In another aspect of the present invention, in the elevator system, a deflector wheel is rotatively provided on the same exterior side surface of the car where the hoisting machine is provided. A first lower pulley is rotatively mounted on the lower surface of the car, and is placed at a position corresponding to the hoisting machine. A second lower pulley which is rotatively mounted on the lower surface of the car, and is placed close to the edge of the car opposite the first lower pulley. Further, the main cable is at one end connected to the upper end of the shaft, and the other end is connected to the upper end of the shaft at a position corresponding to the second lower pulley, as viewed from above. The main cable is wound around the pulley of the counterweight, the top pulley, the deflector wheel, the hoisting machine where a suspension position is formed, the first lower pulley, and the second lower pulley, in this sequence.
- Therefore, the hoisting machine is disposed on the exterior side surface of the car, and the maintenance means is provided on the wall of the car. In the car, a service engineer opens the door of the maintenance means and conducts an inspection of and performs maintenance on the hoisting machine by way of an access port. Thus, the service engineer does not need to stoop to inspect the hoisting machine and can perform operation while in a natural posture. Further, the service engineer is not required to pay special attention so as to avoid accidentally dropping a tool or a like instrument into the shaft, thereby improving the efficiency of maintenance. Further, since the hoisting machine is disposed on the exterior side surface of the car, there can be prevented damage to the hoisting machine, which would otherwise be caused when the lower portion of the shaft is flooded.
- Further, the car is suspended by the main cable, by way of the first and second lower pulley, at a suspension position formed on the deflector wheel, as well as at a position on the lower surface of the car spaced apart from the suspension position in a diagonal direction. As a result, the portion of the car close to its center of gravity is suspended, thereby diminishing an offset load exerted on the car and an offset load exerted on a rail for guiding the car. Consequently, the structure of the elevator system can be simplified, and cost required for constructing the elevator system can be required.
- In another aspect of the present invention, in the elevator system, a deflector wheel is rotatively provided on the same exterior side surface of the car where the hoisting machine is provided. A first side pulley is rotatively provided on the exterior side surface of the car, and is placed at a position corresponding to the hoisting machine. A second side pulley is rotatively provided on the exterior side surface of the car, and is placed at a position spaced apart from the first side pulley. Further, the main cable is connected at one end to the upper end of the shaft, and the other end is connected to the upper end of the shaft at a position corresponding to the second side pulley, as viewed from above. The main cable is wound around the pulley of the counterweight, the top pulley, the hoisting machine where a suspension position is formed, the deflector wheel, the first pulley, and the second side pulley, in this sequence.
- Therefore, the hoisting machine is disposed on the exterior side surface of the car, and the maintenance means is provided on the wall of the car. In the car, a service engineer opens the door of the maintenance means and conducts an inspection of and performs maintenance on the hoisting machine by way of an access port. Thus, the service engineer does not need to stoop to inspect the hoisting machine and can perform operation while in a natural posture. Further, the service engineer is not required to pay special attention so as to prevent avoid accidentally dropping a tool or a like instrument into the shaft, thereby improving the efficiency of maintenance. Further, since the hoisting machine is disposed on the exterior side surface of the car, there can be prevented damage to the hoisting machine, which would otherwise be caused when the lower portion of the shaft is flooded.
- Further, the car is suspended by the main cable, by way of the first and second side pulleys, at a suspension position formed on the deflector wheel, as well as at a position on the lower surface of the car spaced apart from the suspension position in a diagonal direction. As a result, the portion of the car close to its center of gravity is suspended, thereby diminishing an offset load exerted on the car and an offset load exerted on a rail for guiding the car. Consequently, the structure of the elevator system can be simplified, and cost required for constructing the elevator system can be decreased.
- Further, the first and second side pulleys are provided on the side surface of the car, and hence an upper margin space originating from the highest stopping position of the car within the shaft or a lower margin space originating from the lowest stopping position of the car can be diminished, thus shortening the entire length of the shaft. Accordingly, cost incurred for constructing the shaft and installing the elevator system in the shaft can be reduced.
- In another aspect of the present invention, in the elevator system, a first upper pulley is rotatively provided on the upper surface of the car, and is placed at a position corresponding to the hoisting machine. A second upper pulley is rotatively provided on the upper surface of the car, and is placed close to the edge of the upper surface of the car opposite the first upper pulley. Further, the main cable whose is connected at one end to the upper end of the shaft, and the other end is connected to the upper end of the shaft and is placed at a position corresponding to the second upper pulley. The main cable is wound around the pulley of the counterweight, the top pulley, the hoisting machine where a suspension position is formed, the first upper pulley, and the second upper pulley, in this sequence.
- Therefore, the hoisting machine is disposed on the exterior side surface of the car, and the maintenance means is provided on the wall of the car. In the car, a service engineer opens the door of the maintenance means and conducts an inspection of and performs maintenance on the hoisting machine by way of an access port. Thus, the service engineer does not need to stoop to inspect the hoisting machine and can perform operation while in a natural posture. Further, the service engineer is not required to pay special attention so as to avoid accidentally dropping a tool or a like instrument into the shaft, thereby improving the efficiency of maintenance. Further, since the hoisting machine is disposed on the exterior side surface of the car, there can be prevented damage to the hoisting machine, which would otherwise be caused when the lower portion of the shaft is flooded.
- Further, the car is suspended by the main cable, by way of the first and second upper pulleys, at a suspension position formed on the deflector wheel, as well as at a position on the upper surface of the car spaced apart from the suspension position in a diagonal direction. As a result, the portion of the car close to its center of gravity is suspended, thereby diminishing an offset load exerted on the car and an offset load exerted on a rail for guiding the car. Consequently, the structure of the elevator system can be simplified, and cost required for constructing the elevator system can be decreased.
- In another aspect of the present invention, in the elevator system, an indentation is formed in the surface of the counterweight facing the hoisting machine such that the hoisting machine fits into the indentation, as viewed in the horizontal plane of projection.
- Therefore, when viewed within the horizontal plane of projection, the hoisting machine fits into the indentation. Accordingly, the transverse dimension of the shaft can be reduced, and as a result, cost incurred for constructing the shaft and installing the elevator system within the shaft can be reduced.
- In another aspect of the present invention, in the elevator system, an elevator control panel or a console panel for use with the car is provided so as to protrude outwardly on the same wall of the car where the hoisting machine is provided, and is placed at a position spaced apart from the hoisting machine in either side to the vertical direction.
- Therefore, when viewed within the horizontal plane of projection, the hoisting machine, the control panel, and the console panel are arranged so as to overlap one another in the vertical direction of the hoisting machine provided on the wall of the car. Consequently, the area of the hoisting machine within the horizontal plane with respect to the transverse direction can be effectively used. The transverse dimension of the shaft can be reduced accordingly, and as a result, cost incurred for constructing the shaft and installing the elevator system within the shaft can be reduced.
- Obviously many modifications and variations of the present invention are possible in the light of the above teachings. It is therefore to be understood that within the scope of the appended claims the invention may by practiced otherwise than as specifically described.
