Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine room-less elevator device.

[0002]

2. Description of the Related Art In recent years, there is no need to provide a machine room on the roof because a hoist is not required for a conventional hoist-type elevator (no machine room), and a machine room-less elevator that can effectively utilize the height of a building. Apparatus, for example, JP-A-57-1215
No. 68 and JP-A-4-55278 have been proposed. FIG. 13 is an explanatory view showing the entire conventional machine room-less elevator apparatus. FIG. 13A is a plan view of a conventional machine room-less elevator device as viewed from above a hoistway, FIG. 13B is a side view of the elevator device, and FIG. 13C is fishing of the elevator device. It is a front view of a joint weight. FIG. 14A is a plan view of a machine room-less elevator apparatus disclosed in Japanese Patent Laid-Open No. 4-55278, FIG.
(B) is a side view of the elevator device. FIG.
(A) is a plan view of a machine room-less elevator device to which the concept of the elevator device disclosed in Japanese Patent Application Laid-Open No. 57-121568 is applied, and FIG. 15 (b) is a side view of the elevator device. FIG. 16 is a front view of the counterweight of the elevator apparatus of FIGS. 14 and 15. In the figure, 1 is a car, 2 is a counterweight, and the counterweight 2 is provided with an armature 3 of a linear motor. The armature 3 of the linear motor is a secondary conductor 4
To generate a thrust to move the counterweight 2 up and down. The armature 3 of the linear motor is disposed so as to face both surfaces of the secondary conductor 4 of the linear motor, and this type of linear motor is called a double-sided linear motor. Since the car 1 and the counterweight 2 are connected at both ends of the rope 7 via the suspension wheels 5 and 6, the car 1 moves up and down as the counterweight 2 moves up and down.
Reference numeral 8 denotes a hoistway wall, and a counterweight rail 10 and a car rail 11 are fixed to the hoistway wall 8. 9 is the ceiling of the hoistway, and 100 is the entrance of the car.

In a machine room-less elevator device shown in FIG. 15, a rope 7 is fixed to a rope fixing plate 101 provided at the bottom of a car 1 so as to face a counterweight 2, and the rope 7 faces a counterweight 2 of the car 1. This is an example in which a car 1 and a counterweight 2 are connected at both ends of a rope 7 via a suspension wheel 5 installed above the hoistway on the side of the hoistway.

Next, the operation will be described. When a three-phase AC current flows through the armature 3 of the linear motor, a linear magnetic field is generated, and an eddy current is generated in the secondary conductor 4 that engages with the armature 3 of the linear motor, thereby generating a thrust. With this thrust, the counterweight 2 moves up and down, and the car 1 fixed to the rope 7 via the counterweight 2 and the lifting wheels 5 and 6 also moves up and down.

[0005] Since the above-described elevator apparatus without a machine room can be moved up and down by the linear motor incorporated in the counterweight 2, it is not necessary to install a hoist on a hoistway as in a conventional hoist-type elevator apparatus. Becomes Therefore, there is no need to provide a machine room on the roof of the building,
When the height of the building is limited, there is an advantage that the floor can be used effectively.

[0006]

The conventional machine room-less elevator apparatus has the following problems because it is configured as described above. The space between the car 1 and the ceiling 9 of the hoistway is such that if the car goes too high during maintenance or installation, the car will not hit the head with the ceiling of the building or obstacles if the car goes too far. Must be secured. This dimension is called the top clearance safety dimension TC0. The top clearance dimension TC2, which is the space between the ceiling of the car 1 and the ceiling 9 of the hoistway,
Since it is useless space for a building, it is desired that the space be as small as possible. In the configuration of the machine room-less elevator device shown in FIG. 14, since the suspension wheels 5 and 6 are located on the car 1, the dimension TC1 from the ceiling of the car 1 to the suspension wheel 5 is the top clearance safe dimension. That is, since TC1 = TC0, the ceiling 9 of the hoistway is located further above the hoisting wheel 5, so that useless space is increased by the difference between TC1 and TC2. In addition, this method generally requires two hanging wheels, which increases the cost.

[0007] The configuration of the machine room-less elevator device shown in FIG. 15 reduces unnecessary space in the top clearance. That is, instead of suspending the car 1 at the center of the upper part of the car, a rope fixing plate is provided at the lower part of the side of the car 1 facing the counterweight 2 and is suspended from here. By doing so, the hanging wheel 5 can be installed outside the projection plane of the car 1,
The person on the car no longer hits the head on the hanging car 5 and TC
1 can be reduced. The top clearance dimension at this time is TC2. That is, since TC0 = TC2, the ceiling 9 of the hoistway can be lowered to TC1 shown in FIG. In addition, there is only one hanging wheel, which is advantageous in terms of cost. However, there are the following problems.

[0008] The A1 dimension shown in FIG.
Comparing the A2 size shown in (b), the A2 size is substantially larger by the diameter D of the hanging wheel 5. The diameter D of the lifting wheel 5 is
Since the ratio D / d to the rope diameter d is determined from the viewpoint of the life of the rope, the diameter of the hanging wheel 5 cannot be reduced to a predetermined value or more. Therefore, since the actual dimensions are A1 <A2, the hoistway dimension A0 shown in FIG. 14A becomes large, and the effective use area in the building is reduced.

[0009] In addition, the machine room-less elevator system has a safety measure at the time of installation and maintenance of the elevator system, from the viewpoint of reducing the top clearance dimension and effectively using the height of the building, thereby reducing the safety of the top clearance. It is required to reduce the dimension TC0 itself to reduce the top clearance dimension to the limit.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and the height of the building is effectively used by reducing the top clearance dimension TC2. You can work safely even if it is less than the value,
Another object is to provide an inexpensive machine room-less elevator device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1A is a plan view of an elevator apparatus without a machine room according to an embodiment of the present invention. FIG. 1B is a side view of FIG. In the figure, the same reference numerals as those in FIG. 13 indicate the same or corresponding parts. In the figure, reference numeral 101 denotes a rope fixing plate attached to the lower part of the car 1, and one end of the rope 7 is fixed to the rope fixing plate 101. The other end of the rope 7 is fixed to the counterweight 2 via the hanging wheel 5. The armature 3 of the linear motor mounted on the counterweight 2 is installed only on one side of the counterweight as shown in the figure. With this configuration, the hoisting wheel 5 is installed on the counterweight 2 side outside the car 1 above the hoistway 8, and the end of the counterweight 2 where the armature 3 of the linear motor is not mounted. The rope 7 can be fixed to the top of the car, so that the hanging wheel 5 can be installed with a large angle θ with respect to the center line L1 connecting the car 1 and the counterweight 2. With this configuration, the A3 dimension can be reduced from the A2 dimension in FIG. 1
Numeral 0 is a rail for a counterweight. Further, since the hanging car 5 is installed outside the counterweight 2 side of the car 1 at the upper part of the hoistway 8, even if a person works on the ceiling of the car 1, the head hits the hanging car 5. No safety gap at the top TC
Since 0 = top clearance TC2, the height of the building can be effectively utilized. Here, the case where the armature 3 of the linear motor is installed on one side of the counterweight 2 has been described, but the case where the armature 3 of the linear motor shown in FIG. Although the angle θ cannot be made large, the A3 dimension can be made smaller than the A2 dimension by taking the angle θ within a space-permissible range.

Embodiment 2 2 and 3 are explanatory views showing another embodiment of the present invention. In the figure, the same reference numerals as those in FIG. 16 indicate the same or corresponding parts. In the figure, reference numeral 101 denotes a rope fixing plate attached to the lower part of the car 1, and one end of each of a pair of ropes 7 is fixed to the pair of rope fixing plates 101. A pair of ropes 7 via the hanging wheels 25 and 26
The other end of each of the rope fixing portions 10 of the counterweight 2
It is fixed to 2. The rope fixing plate 101 and the rope fixing portion 102 are attached so as not to interfere with each other during the ascent and descent. The hoisting wheels 25 and 26 are mounted at a position lower than the ceiling 9 of the hoistway by a mounting member 27 in parallel with the center line of the rail 10, and the car 1 reaches the top floor at a portion where the car 1 does not hit the hoistway. At times, it is installed in the same or lower part as the ceiling of the car 1. FIG. 3 shows a state in which the car 1 reaches the top floor in this embodiment, 19 is a door on the building side of the top floor, and 20 is a passenger in the car 1. In this case, when the car 1 is on the top floor, the hanging wheels 25 and 26 are located lower than the ceiling of the car 1, so that the top clearance TC2 can be minimized, and the height of the building can be reduced to the maximum. Can be used for

Embodiment 3 FIG. 4 shows another mode of mounting the armature 3 on the counterweight 2 of the linear motor mounted on the counterweight 2 in the second embodiment. In the figure, an armature 3 of a linear motor mounted on a center portion of a counterweight 2 is mounted vertically on a facing surface of the car 1 and the counterweight 2, and a secondary conductor 4 is also provided on the armature 3 of the linear motor.
And are arranged in the same direction so as to be engaged. As in the second embodiment, one end of each of the pair of ropes 7 is fixed to the pair of rope fixing plates 101, and the other end of each of the pair of ropes 7 is counterweighted via the suspension wheels 25 and 26. 2 is fixed to each of the rope fixing portions 102. The rope fixing plate 101 and the rope fixing portion 102 are attached so as not to interfere with each other during the ascent and descent. The state of the hanging wheels 25 and 26 and the car 1 when the car 1 reaches the landing on the top floor is shown in FIG. Is the same as In this embodiment, the counterweight 2
Armature 3 of the linear motor mounted in the center of
The thickness D of the counterweight 2 can be made smaller than the counterweight shown in FIG. 2 because the counterweight 2 is mounted vertically on the opposing surface of the counterweight 2.

Embodiment 4 In the machine room-less elevator apparatus of the present invention, as shown in FIGS.
5 is suspended by the rope 7 fixed to the rope fixing plate 101 provided at the bottom on one side of FIG.
Is applied. Therefore, the car 1 is moved up and down along the car rail 11 by the rollers 30.
A, 30B, 30C, and 30D guide the moment F1 to the car rail 11 and the roller 30B.
Between them, there is a problem such as generating a vertical sound or accelerating the wear of the rollers. FIG. 5 shows an embodiment of this measure. In the figure, the rope 31 is engaged with a spring 33 fixed to the upper portion on the opposite side of the car 1 on which the rope fixing plate 101 is provided and fixed to the counterweight 2 via the suspension wheel 31. Since the spring 33 applies a constant tension to the rope 31, the rope 31 generates a moment F2 in a direction to cancel the moment F1, weakens the force applied between the car rail 11 and the roller 30B, and raises and lowers the noise of the roller. Reduce wear.

FIG. 8 is a side view of FIG.
The force F3 is attached to the upper part of the car 1 so that the force F3 acts efficiently on the moment F1. Since the force F3 of the electromagnets 43 and 44 acts in a direction to cancel the moment F1, the force applied between the car rail 11 and the rollers 37 and 39 is weakened, and the vertical noise and the wear of the rollers are suppressed.

Embodiment 6 FIG. The machine room-less elevator device having the configuration shown in Embodiments 1, 2, and 3
Since the members 25 and 26 do not interfere with the car 1 that is moving up and down, the car 1 can go up to just below the ceiling 9 of the hoistway. However, while the height of the building can be used effectively, the safety dimension TC0 at the top is reduced, so that it is necessary to work safely during installation and maintenance. In the embodiment of the machine room-less elevator apparatus of the present invention, as a countermeasure for reducing the top safety dimension TC0, an inspection work can be performed safely without the operator getting on the car 1. FIG. 9 is a side view of the machine room-less elevator apparatus of the present invention, showing a state where the elevator apparatus stops at the top floor.

In some cases, a brake device (not shown) for stopping the raising and lowering of the car 1 is engaged in the vicinity of the hoisting wheels 25, 26 for performing inspections on the wheels 5, 26. In this case, the brake devices can also be inspected. Further, by lowering the position of the car 1 and stopping it at the same height as the counterweight 2, it is also possible to inspect the armature 3 of the linear motor disposed on the counterweight 2, the brake device 13, and the like.

FIG. 10 is a side view showing another embodiment of the machine room-less elevator apparatus of the present invention, and shows a state where the elevator apparatus is stopped at the top floor. In the drawing, 21A is an inspection opening provided on the building side of the hoistway wall facing the counterweight 2. The inspection opening 21A is closed by a locked door during normal operation.
B can open the door and inspect the hanging wheels 25, 26 and the attached devices of the hanging wheels 25, 26 from the inspection opening 21A.

Embodiment 7 In the sixth embodiment, the example of the inspection work performed without riding on the top of the car 1 has been described.
It may be necessary to get on top of the car 1 depending on the work content. In this case, since the top safety dimension TC0 when the car 1 is on the top floor is reduced, there is a danger that the worker working on the car 1 may hit the head on the ceiling of the hoistway. Danger prevention measures are required. An embodiment of the machine room-less elevator apparatus according to the present invention employs a top safety dimension TC0.
As a countermeasure for the decrease in the number of workers, a worker working on the car 1 can perform an inspection work safely. FIG. 11 is a side view of the machine room-less elevator apparatus of the present invention, showing a state where an operator is inspecting equipment provided on the top floor. In the figure, reference numeral 57 denotes a light emitting device of a human body detection sensor that detects an operator who is working above the car 1 and is constituted by a light receiving device 51 that receives light from the light emitting device 50 and outputs a signal. When the worker is working on the car 1, the light-emitting device 50 blocks the light emitted from the light emitting device 50, and the light receiving device 51 stops the output signal to the control device of the linear motor driving device (not shown). Controls the elevation of the car 1 so that the car 1 secures a predetermined top safety dimension TC0, or performs control such that the car 1 can be operated only at a maintenance speed equal to or lower than a predetermined speed.

An inspection stopper 52 is provided at the bottom of the hoistway so as to be detachable. Inspection stopper 5
Numeral 2 stands upright at the bottom of the hoistway during maintenance, and engages with the lower portion of the counterweight 2 to prevent the car 1 from rising to a position below the predetermined top safety dimension TC0. With this configuration, the predetermined top safety dimension TC0 is secured by the human body detection sensor 57 or the inspection stopper 52, so that the worker can safely work on the upper part of the car 1.

Embodiment 8 FIG. FIG. 12 is an explanatory view of a machine room-less elevator apparatus showing another embodiment of safety measures for inspection work near the top floor. In the drawing, reference numeral 53 denotes a storage space FG where the car 1 and the counterweight 2 are opposed to each other during normal operation, and is used by closing the elevator of the car 1 and closing it to a position EF substantially coincident with the top floor during inspection. Is an inspection scaffold supported at the F section in the hoistway as described above. The inspection scaffold 53
The tip is tied to a wire 54, and the wire 54 is tied to a hand-wound handle 55 via a roller 56 so that the wire 54 can be operated from the building side. When the hand-wound handle 55 is turned, it falls from the FG position to the EF position. When turned in the opposite direction, it returns from the EF position to the FG position. Further, by providing a sensor (not shown) for detecting that the inspection scaffold 53 is not at the fixed position FG, it is possible to prevent the car 1 from running away to the inspection scaffold 53 due to an erroneous operation of the elevator apparatus. With this configuration, when the inspection scaffold 53 is at the EF position, the worker 20C can move onto the inspection scaffold 53 from the building side door 19 and work safely.
