Description

Elevator device {ELEVATOR APPARATUS}

The present invention relates to an elevator apparatus including a car, a counterweight, a rope for suspending both, a winch for driving the rope, and a direction -change-pulley for changing the suspension direction of the rope in a hoistway. will be.

12 and 13 are, for example, a plan view and a side view of a conventional elevator apparatus shown in FIGS. 2 and 1 of Japanese Patent Application Laid-Open No. 9-165172.

In the figure, 1 is a car carrying a person or cargo, 2 is a counterweight to compensate for the weight of the car 1, 3 is a rope suspending the car 1 and the counterweight 2, 4 is a rope 3 Thin hoist to drive and lift car 1 and counterweight 2, 4a is sheave of hoist, 5a, 5b is direction change pulley to change suspension direction of rope 3, 6 is car Guide rails for guides, 7 for counterweight guide rails, 8 for hoists, 11 for suspension pulleys for cars (1), 12 for suspension pulleys for counterweights (2), 13 for rope fixings on the side of cars, 14 for It is a rope fixing part on the counterweight side.

Next, the conventional elevator apparatus is demonstrated with reference to FIGS. 12-13.

The car 1 and the counterweight 2 of the elevator are lifted and lifted by the rope 3 suspended on the sheave 4A of the winch 4. At this time, the guide rail for car 6 regulates the horizontal movement of the car 1, and the counterweight guide rail 7 regulates the horizontal movement of the counterweight 2 so that Contact and interference with the car 1 and the counterweight 2 are prevented. Here, the vertical projections of the car 1, the counterweight 2 and the winch 4 are separated from each other, and the winch 4 is placed in parallel with one adjacent wall surface.

In recent elevator devices, various types of elevator devices have been proposed in which a hoist is built into a hoistway without installing a machine room in order to minimize the occupied space of the elevator device. Specifically, (1) a method of arranging a thin hoist above the height of the counterweight, and (2) a hoist of the hoist above the top of the hoistway, that is, above the ceiling of the car when the car stops on the top floor. (3) The hoisting device is a pit part in the hoistway, that is, a method in which the car is disposed below the bottom surface of the car when the car stops at the lowest floor.

Among these systems, (1) and (2) require a hoistway height higher than the minimum height required for hoisting of the elevator. In addition, on the car near the top of the hoistway, there is a drawback in that a protective measure must be taken to prevent an operator from hitting the head of the hoistway by an unexpected rise of the car during maintenance of the hoist.

In the case of the system (2), since the heat generated in the winches stays at the top of the hoistway, that is, in the vicinity of the winches themselves, the winches easily break due to the temperature rise.

Method (3) has the drawback of requiring protective means since the hoist is arranged at the pit part which is most easily filled with water. Although the elevator apparatus of Japanese Patent Laid-Open No. 9-165172 can eliminate the drawback of the method (1), it causes a new drawback in which unused space is generated over the entire height of the hoistway above and below the vertical projection surface of the hoisting machine. .

As mentioned above, in the conventional elevator apparatus, there existed a fault which the unused space generate | occur | produces over the whole height of the hoistway above and below the vertical projection surface of a winch.

It is an object of the present invention to provide an elevator apparatus for solving the above-described problems.

Example 1.

1 to 3, a first embodiment of the present invention for an elevator apparatus will be described.

1 is a perspective view of Embodiment 1 of an elevator apparatus of the present invention, and FIG. 2 is a plan view.

This is an example in which the counterweight is arranged at the rear of the car and the winch is arranged at the side of the car as viewed from the elevator hatch. In the figure, 1 is a car carrying passengers or cargo, 2 is a counterweight to compensate for the weight of the car 1, 3 is a rope suspending the car 1 and the counterweight 2, and 4 is a rope 3 Is a thin hoist which drives and lifts the car 1 and the counterweight 2 through 4), 4a is a sheave of the hoist 4, 4b is a motor of the hoist 4, and 5a and 5b are ropes 3 It is a turning pulley for switching the suspension direction of, 6 is a guide rail for guiding the car, 7 is a guide rail for guiding the counterweight, 8 is a hoistway, 8a is a top portion of the hoistway (8), 8b is a pit portion of the hoistway 8, 9 is a beam supporting the winch 4, 10 is a beam supporting the turning pulleys 5a, 5b, and 11 is Suspension pulley for car (1), 12 is suspension pulley for counterweight (2), 13 is rope fixing part on the car side, 14 is rope fixing part on the counterweight side, 15 is Control panel. In addition, the dashed-dotted line A in FIG. 1 shows the height of a car ceiling when a car stops at the lowest floor.

That is, the upper part of this dashed-dotted line A is a normal part. In addition, the dashed-dotted line B in FIG. 1 shows the height of the bottom surface of a car when a car stops at the lowest layer. That is, the lower part of this dashed-dotted line B is a pit part.

In the figure, the lower end of the winch 4 is above the dashed-dotted line B. As shown in FIG. That is, the winch 4 is disposed below the car ceiling when the car stops at the top floor, and the lower end of the winch is disposed above the bottom of the car when the car stops at the top floor. Moreover, the winding machine 4 is arrange | positioned in parallel with the adjacent one wall.

Moreover, the direction change pulley 5a is arrange | positioned partly overlapping with the winch machine 4 on the projection face of the horizontal cross section of the hoistway 8. The turning pulley 5b is arranged inclined with respect to the wall surface.

The winch machine 4 is fixed to the lower side of the beam 9 supported by the car guide rail 6 and the counterweight guide rail 7. The sheave 4a of the winch 4 is located on the car side rather than the rear surface of the car guide rail 6 on the horizontal cross section of the hoistway 8. Here, the back of the guide rail refers to part C of FIG. 3. In this example, the winch 4 is fixed directly to the beam 9, but the winch 4 may be attached to the beam 9 via an elastic body to form a vibration proof structure. In addition, an elastic body may be attached between the beam 9 and the car guide rail 6 and between the beam 9 and the counterweight guide rail 7.

Moreover, the direction change pulleys 5a and 5b are fixed to the beam 10 supported by the car guide rail 6 and the counterweight guide rail 7. In this example, the diverting pulleys 5a and 5b are directly fixed to the beam 10, but the diverting pulleys 5a and 5b are attached to the beam 10 so as to construct a dustproof structure through an elastic body. You may. In addition, an elastic body may be attached between the beam 10 and the car guide rail 6 and between the beam 10 and the counterweight guide rail 7.

Moreover, the control panel 15 is arrange | positioned so that the lower end of the control panel 15 may be located above the bottom surface of a car when a car stops at the lowest floor. In other words, the control panel 15 is disposed at almost the same height as the winch 4. The rope 3 suspended by the sheave 4a of the winch 4 driven by the control panel 15 is diverted by the turning pulleys 5a and 5b, and the suspension pulley 11 for the car and the counter. The car 1 and the counterweight 2 are moved up and down through the weight suspension pulley 12.

At this time, the car guide rail 6 and the counterweight guide rail 7 restrict the horizontal movement of the car 1 and the counterweight 2.

The turning pulley 5a is arranged to partially overlap with the winch 4 on the projection surface of the horizontal section of the hoistway 8, and the sheave 4a of the hoist 4 is guided for the car in the horizontal cross section of the hoistway 8. Since it is located on the car side rather than the back side of (6), the area occupied by the winch machine 4 on the projection surface of the horizontal cross section of the hoistway 8 is reduced, and the unused space with respect to the overall height of the hoistway can be reduced. In addition, since the wrapping angle of the rope wound around the sheave 4a of the winch can be made larger than 180 °, the traction capacity can be increased. Moreover, since the hoist 4 is arrange | positioned below the car top information when a car stops on the uppermost floor, there is no fear that the inspection worker who works on a car may hit his head to the ceiling of the hoistway by the unexpected rise of the car. No means is required. In addition, since the heat generated by the hoisting machine dissipates above the ceiling of the hoistway, the hoisting machine does not fail due to the temperature rise. Moreover, since the direction change pulley 5b is inclined with respect to the wall surface of the hoistway 8, the input angle which the rope 3 enters the rope groove of the sheave 4a becomes small, and can prevent damage to a rope.

Moreover, since the winch 4 is attached to the lower part of the beam 9, and the diverting pulleys 5a and 5b are attached to the beam 10, the guide rail 6 for a car through the beam 9, Acting on the car guide rail 6 and the counterweight guide rail 7 through the upward force and beam 10 generated by the tension of the rope 3 acting on the counterweight guide rail 7. The downward force generated by the tension of the rope 3 is offset inside the guide rail, thereby reducing the force provided to the building.

In addition, the lower end of the winch 4 and the lower end of the control panel 15 are respectively located above the bottom of the car when the car stops at the lowest floor, and located below the car ceiling, so that the pit can be irrigated (cover with water). There is no damage.

In elevators without a machine room of this type, the depth of the pit is between 1.2 m and 1.5 m, and if the winch and control panel are located at this position, the reach of the operator when the operator stands on the floor of the pit, for example 1.2 m. It is in the range of 1.7m in height (when the car stops on the lowest floor, the floor height of the car is 1.7m from the bottom of the pit), making inspection easy.

When the lower end of the winch 4 and the lower end of the control panel 15 are disposed above the bottom of the car when the car stops on the first floor, and below the car ceiling, the entire basement floor is not only water. Even if reversed, the winch 4 and the control panel 15 are not damaged.

In addition, when the lower end of the winch machine 4 is disposed above the bottom of the car when the car reference floor is stopped, and is disposed below the car ceiling, and the control panel 15 is disposed at about the same height, an inspection suitable for the operation management of the elevator device is performed. This is easiest to do.

When the lower end of the hoist 4 is disposed above the bottom of the car when the car stops on the uppermost floor, and below the ceiling surface of the car, the heights of the hoist 4 and the turning pulleys 5a and 5b are Since is located close, it can be convenient to check both.

In addition, by integrating beams supporting both, materials can be saved and space can be reduced.

4 and 5, a second embodiment of the present invention relating to an elevator apparatus will be described below.

4 is a perspective view of Embodiment 2 of an elevator apparatus of the present invention, and FIG. 5 is a plan view. This is an example in which the counterweight is arranged at the rear of the car and the winch is arranged to the side of the lifting space of the counterweight as viewed from the elevator hatch. In the drawings, the same reference numerals as the drawings described above indicate the same parts, and thus description thereof will be omitted.

In the figure, the lower end of the winch 4 is located above the dashed-dotted line B. FIG. That is, the winch machine 4 is arrange | positioned below the lower side of the cloth of the car when the car stops on the uppermost floor, and the lower end is arrange | positioned above the bottom surface of the car when the car stops on the lowest floor.

Moreover, the winding machine 4 is arrange | positioned in parallel with the adjacent one wall.

Moreover, the direction change pulleys 5a and 5b are arrange | positioned partially overlapping with the winch machine 4 on the projection surface of the horizontal cross section of the hoistway 8. In addition, since the turning pulley 5b is inclined with respect to the wall surface of the hoistway 8, the angle of entry of the rope 3 relative to the rope groove of the sheave 4a becomes small, and damage to the rope can be prevented.

In addition, the winch machine 4 is fixed to the beam 9 supported by the car guide rail 6 and the counterweight guide rail 7 from below. In this example, the winch 4 is directly fixed to the beam 9, but may be fixed to the beam so as to constitute a dustproof structure through an elastic body. The beam 9 can also be attached to the car guide rail 6 and the counterweight guide rail 7 via an elastic body.

Further, the direction change pulleys 5a and 5b are fixed to the beam 10 supported by the car guide rail 6 and the counterweight guide rail 7.

In the present example, the diverting pulleys 5a and 5b are directly fixed to the beam 10, but may be fixed to the beam 10 so as to form an attachment dustproof structure through an elastic body.

The beam 10 can also be attached to the car guide rail 6 and the counterweight guide rail 7 via an elastic body.

Moreover, the control panel 15 is arrange | positioned on the horizontal cross section of the hoistway 8, just above or just below which the projection surface of the control panel overlaps with the winch 4.

The rope 3 suspended by the sheave 4a of the winch 4 driven by the control panel 15 is diverted by the turning pulleys 5a and 5b, and the suspension pulley 11 for the car and the counter. The car 1 and the counterweight 2 are moved up and down through the weight suspension pulley 12. At this time, the car guide rail 6 and the counterweight guide rail 7 restrict the horizontal movement of the car 1 and the counterweight 2.

The turning pulley 5a is partially overlapped with the hoist 4 on the projection surface of the horizontal section of the hoistway 8, and the control panel 15 has the projection surface of the control panel 15 at the horizontal cross section of the hoistway 8. Since it is located directly above or just below, the area occupied by the winch 4 on the projection surface of the horizontal section of the hoistway 8 is reduced. In addition, the hoist 4 is arranged under the car ceiling when the car stops on the top floor. Therefore, the head of the maintenance worker on the ceiling of the hoistway when the maintenance worker performs the maintenance work on the hoist of the car at the top of the hoistway. Does not collide unpredictably and does not require protective measures. In addition, the heat generated by the hoisting machine is dissipated above the ceiling of the hoistway so that the hoisting machine is not broken by the temperature rise.

In addition, since the winch 4 is attached to the beam 9 and the turning pulleys 5a and 5b are attached to the beam 10, the guide rails 6 and the counterweight for the car through the beam 9 are provided. The upward force generated by the tension of the rope 3 acting on the guide rail 7 for the car, and the rope acting on the car guide rail 6 and the counterweight guide rail 7 through the beam 10 ( The downward force generated by the tension in 3) is canceled inside the guide rail, thereby reducing the force provided to the building.

The lower end of the winch 4 is located above the bottom of the car when the car stops on the lowermost floor. The control panel 15 has a projection surface of the winch 8 on a horizontal cross section of the hoistway 8. Since it is arrange | positioned directly above or just below the closest overlapping with (), even when a pit part is watered by water, the winch | pulge machine 4 and the control panel 15 are not damaged by water.

In an elevator unit without a machine room of this type, the depth of the pit is about 1.2 m to 1.5 m. If the winch and control panel are in this position, the reach of the hand when the operator stands on the pit floor, for example, a height range from 1.2 m to 1.7 m (the height of the bottom of the car when the car stops at the lowest floor 1.7m from the bottom), making maintenance easy.

Further, the lower end of the winch 4 is disposed above the bottom of the car when the car 1 stops on the first floor, and below the car ceiling, so that the control panel 15 is placed on the horizontal section of the hoistway 8. When the projection surface of the winch machine 4 is disposed directly above or just below the closest overlapping with the winch machine 4, the winch machine 4 and the control panel 15 are damaged even if water flows not only into the pits but also through the basement floor. There is no

Further, the lower end of the winch 4 is disposed above the bottom of the car when the car stops on the reference floor, and the control panel 15 is located immediately above or near the top of which the projection surface overlaps the winch 4 at the horizontal section of the hoistway 8. If it is located directly below, the inspection work according to the operation management of the elevator can be performed most easily.

The lower end of the winch 4 is disposed above the bottom of the car when the car stops on the top floor, and the winch 4 and the turning pulleys 5a and 5b when the car is positioned below the car ceiling. Since the height of is approached, it is convenient to check both.

In addition, by integrating the beams supporting both, the material can be saved and the space can be reduced.

Example 3.

6, 7, and 3, Embodiment 3 of the present invention for an elevator apparatus will be described.

FIG. 6 is a perspective view of Embodiment 3 of an elevator apparatus of the present invention, and FIG. 7 shows a plan view. This is an example in which the counterweight is arranged on the side of the car as viewed from the elevator door, and the hoisting machine is arranged such that the projection surface of the hoisting machine does not overlap the counterweight on the horizontal section of the hoistway on the same side as the counterweight.

In the drawings, the same reference numerals as the above-described drawings denote the same parts, and thus description thereof will be omitted.

In the figure, the lower end of the winch 4 is located above the dashed-dotted line B. FIG. That is, the winch machine 4 is arrange | positioned in the lower position lower than the cloth | cloth information of the car when the car stops on the uppermost floor, and the lower end is arrange | positioned in the position above the bottom surface of the car when the car stops on the lowest floor.

Moreover, the winding machine 4 is arrange | positioned in parallel with the adjacent one wall.

Moreover, the direction change pulley 5a is arrange | positioned partly overlapping with the winch machine 4 on the projection surface of the horizontal cross section of the hoistway 8. In addition, since the turning pulleys 5a and 5b are configured to be inclined with respect to the wall surface of the hoistway 8, the angle of insertion of the rope 3 with respect to the sheave 4a can be reduced to prevent damage to the rope. .

The winding machine 4 is fixed to the beam 9 supported by the car guide rail 6 and the counterweight guide rail 7 from below.

The motor 4b of the winch 4 is located on the rear car side of the car guide rail 6 in the horizontal cross section of the hoistway 8. Here, the back of the guide rail refers to part C of FIG. 3. In this example, the winch 4 is directly fixed to the beam 9, but may be fixed to the beam so as to constitute a dustproof structure through an elastic body. The beam 9 can also be attached to the car guide rail 6 and the counterweight guide rail 7 via an elastic body.

Moreover, the direction change pulleys 5a and 5b are fixed to the beam 10 supported by the car guide rail 6 and the counterweight guide rail 7. In this example, the diverting pulleys 5a and 5b are directly fixed to the beam 10, but may be fixed to the beam 10 so as to be of a dustproof structure through an elastic body.

The beam 10 can also be attached to the car guide rail 6 and the counterweight guide rail 7 via an elastic body.

The rope 3 suspended by the sheave 4a of the winch 4 driven by the control panel 15 is diverted by the diverting pulleys 5a, 5b, and the suspension pulley 11 for the car and the counter. The car 1 and the counterweight 2 can be lifted and lowered through the weight suspension pulley 12. At this time, the car guide rail 6 and the counterweight guide rail 7 restrict the horizontal movement of the car 1 and the counterweight 2.

The turning pulley 5a is partially overlapped with the winch 4 on the projected surface of the horizontal section of the hoistway 8, and the motor 4b of the hoist 4 is guide rail for the car in the horizontal section of the hoistway 8. Since it is located on the car side rather than the back of (6), the area occupied by the winch machine 4 on the projection surface of the horizontal cross section of the hoistway 8 is reduced. In addition, since the hoist 4 is disposed below the car ceiling when the car stops on the top floor, the head of the maintenance worker on the ceiling of the hoistway when the maintenance worker performs the maintenance work on the hoist of the car at the top of the hoistway. Does not collide unpredictably and does not require protective means.

In addition, the hoist is not broken by the temperature rise.

Moreover, since the winch | winder 4 is attached under the beam 9, and the direction change pulley 5a, 5b is attached to the beam 10, the guide rail 6 for a car through the beam 9, The upward force generated by the tension of the rope 3 acting on the counterweight guide rail 7 and the beam guide 10 act on the car guide rail 6 and the counterweight guide rail 7. The downward force generated by the tension of the rope 3 is canceled inside the guide rail, and the force provided to the building can be reduced.

Further, the lower end of the winch 4 and the lower end of the control panel 15 are respectively disposed at the upper position of the car bottom when the car stops on the lowermost floor, and are also positioned at the lower position of the car ceiling, so that even if the pit is irrigated with water, 4) and the control panel 15 are not damaged.

In this type of machine roomless elevator, the pit depths range from 1.2 m to 1.7 m. When the lifter and the control panel are placed in this position, the reach of the maintenance worker when standing on the pit floor, for example, in the range of 1.2 m to 1.7 m height (the height of the bottom of the car when the car stops on the lowest floor is the pit bottom). Is 1.7m), so maintenance work is easy.

Moreover, the lower end of the winch machine 4 is arrange | positioned in the upper position of a car bottom surface when a car stops on the 1st floor, and the upper end of the winches is arrange | positioned in a position below a car ceiling surface, and the control panel 15 is about the same height. In this case, the winch 4 and the control panel 15 are not damaged even if the entire basement floor is filled with water as well as the pits.

Moreover, the lower end of the winch machine 4 is arrange | positioned in the upper position of a car bottom surface when a car stops on a reference floor, and the upper end of the winch machine is arrange | positioned in a position below a car ceiling surface, and the control panel 15 is located in substantially the same height. In the case of arrangement, the maintenance for the operation of the elevator device can be performed most easily.

The lower end of the winch 4 is disposed at a position above the bottom of the car when the car stops on the uppermost floor, and the winch 4 and the turning pulley 5a when the upper end of the winch is disposed at a position lower than the top of the car ceiling. Since () and (5b) are located close to the height, both can simplify maintenance.

Example 4.

An embodiment 4 of the present invention for an elevator apparatus is described below with reference to FIGS. 8 to 10.

Fig. 8 is a perspective view of Embodiment 4 of the elevator apparatus of the present invention, Fig. 2 shows a plan view, and Figs. 9 and 10 show principal parts, respectively. This is seen from the elevator's hatch, below the beam supporting the diverting pulley, with the counterweight placed at the rear of the car and at the side of the car and just below the car ceiling height when the winch stops on the top floor. It is an example arranged. Like reference numerals in the drawings indicate like parts, and descriptions thereof will be omitted.

In the figure, 16 is an elastic body that absorbs the vibration of the beam 10.

Here, the inclination angle with respect to the hoistway walls of the diverting pulleys 5a and 5b can be changed and the spacing between the two diverting pulleys 5a and 5b can also be changed. This variable structure can be realized if, for example, the beam 10 and the frames of the turning pulleys 5a and 5b are bolted to each other and the fixing holes are formed into long holes. However, the variable structure is not limited to this embodiment. This variable structure can also be applied to the first to third embodiments.

Since the winch machine 4 is attached to the lower part of the beam 10 which supports the direction change pulley 5a, 5b, the force which acts upward of the sheave 4a of the winch machine 4 by tension, The forces acting downward on the diverting pulleys 5a and 5b cancel each other out. In other words, the forces acting on the beam 10 cancel each other as inner forces. Therefore, the force acting on the guide rail can be reduced.

In addition, since the winches 4 and the turning pulleys 5a and 5b are attached to the same beam 10, the positional adjustment can be facilitated.

In addition, the winch 4 and the turning pulleys 5a and 5b are attached to the same beam 10, and the beam 10 passes through the elastic body 16 of the car guide rail 6 and the counterweight. Since it is attached to the guide rail 7, it is possible to effectively insulate the vibrations of the winch 4 and the turning pulleys 5a, 5b.

Moreover, since the inclination angle with the hoistway walls of the diverting pulleys 5a and 5b is variable, and the spacing between the two diverting pulleys 5a and 5b is also variable, it is possible to use the car in different sizes of cars 1. The same design can be applied even if the positional relationship in the plane of the hoistway between the suspension pulley 11 and the suspension weight pulley 12 for the counterweight is changed.

In the drawings, the same reference numerals as the drawings described above indicate the same parts and the description thereof will be omitted. In the figure, 17 is a driving device in which one of the two turning pulleys 5a and 5b is replaced. This substitution can be applied to Examples 1 to 4.

When one of the two diverting pulleys 5a, 5b is replaced by the drive unit 17 and synchronized with the winch 4, the driving ability can be improved, and it is also applied to a large-capacity elevator unit. You can do it.
