Therefore, the sensors detect the change of the combination so as to use information about the relation of the sill position for controlling drive and safely traveling an elevator.

Description

Lifting device of elevator {ELEVATOR LANDING APPARATUS}

The present invention relates to an elevator apparatus in which the elevating vessel suspended by a rope moves up and down within a hoistway, and in particular, an apparatus for positioning the elevator at a position where the threshold of the elevator platform and the threshold of the hoist are on the same plane. It is about.

As an apparatus for implanting this kind of elevator, conventionally, the apparatus 91 shown in FIGS. 1 and 2 and the apparatus 101 shown in FIG. 3 and Japanese Unexamined Patent Application Publication No. 64-6110 are known.

The implantation apparatus 91 of the elevator 81 illustrated in FIG. 1 and FIG. 2 is mounted via a detector 92 provided at an upper portion of the lift box 34 and an arm 93 on the guide rail 83 (hereinafter, referred to as an attachment device 91). And a detection plate 94 (called mounting). The detector 92 is provided with a signal transmitter 95 and a signal receiver 96 which are arranged to be spaced apart from each other. The signal transmitter 95 is configured to emit a signal toward the signal receiver 96.

The detection plate 94 is formed of a material that shields the signal emitted from the signal transmitting unit 95, and the lifting unit 84 moves up and down at a position where the threshold portions of the landing board and the lifting board 84 are flush with each other. In this position, it is provided on the side of the guide rail 83 at a position inserted between the signal transmitting unit 95 and the signal receiving unit 96.

When the detection plate 94 is inserted between the signal transmitter 95 and the signal receiver 96 so that the signal receiver 96 does not receive a signal transmitted from the signal transmitter 95, Then, the elevating box 84 is stopped to position at the position where the threshold portions are flush with each other.

The implantation apparatus 101 shown in JP-A-616110 shown in FIG. 3 is provided with a detector 102 installed on the threshold 85 of the elevator 84 and a threshold 87 of the landing 86. The to-be-detected object 103 is provided. The detector 102 and the to-be-detected object 103 are made to face each other when the lift 84 is located at a position where the threshold portions 85 and 87 are flush with each other.

The detector 102 has a signal transmitter for emitting a signal and a signal receiver for receiving a signal. The object to be detected 103 reflects the signal transmitted from the signal transmission unit and guides the signal to the signal reception unit.

When the detector 102 and the to-be-detected object 103 face each other, the implantation apparatus 101 moves up and down by reflecting the signal transmitted from the signal-transmission part by the to-be-detected object 103 and receiving the signal ( A drive mechanism (not shown) is operated to stop 84 and position the lift 84 at a position where the threshold portions 85 and 87 are flush with each other.

The implantation apparatus 91 of the elevator 81 illustrated in FIGS. 1 and 2 stops the elevating 84 from the position where the threshold portions are flush with each other when the elevator 81 is constructed in an elevator hoistway of a building. In order to do this, the position along the vertical direction of the detection plate 94 had to be adjusted minutely.

Also, when the elevator 84 moves up and down, the detection plate 94 and the detector 92 can pass between the signal transmitter 95 and the signal receiver 96 without contacting the detector 92. It was necessary to adjust the position of each other in the publication 94. Therefore, the effort and effort at the time of construction tended to increase, and the cost at the time of construction tended to rise.

In addition, the implantation apparatus 101 shown in JP-A No. 64-6110 includes a detector 102 that opposes each other in a narrow space of the threshold portion 85 of the elevator 84 and the threshold portion 87 of the landing 86. Since the to-be-detected object 103 is provided, the signal transmitted from the signal transmission part of the detector 102 may be reflected by the aperon etc. which were attached to the wall surface of the elevator hoistway, the boarding point 86, etc. .

For this reason, the signal receiver receives a signal reflected by an apron or the like for maintaining a predetermined gap between the wall of the elevator hoistway and the hoist and the hoist, and malfunctions, thereby positioning the hoist 84 at a predetermined position. There was nothing.

It is an object of the present invention to restrain effort and effort in construction, thereby restraining the cost of construction, and at the same time restraining malfunctions to ensure that the platform and the threshold of the elevator are lifted to the same plane. It is to provide an implantation apparatus of an elevator that makes it possible to determine.

The said subject is achieved by the following frosting apparatus of an elevator. That is, according to the present invention, a detector is mounted on one of the thresholds of the elevator platform installed in the building and the threshold of the elevator lift, and the other side is mounted on the other side, and the platform is used by opposing the detector and the target body. In the lifting device of the elevator for positioning the lift at a position where the threshold of the threshold and the threshold of the lift is the same plane,

One of the detector and the to-be-detected body is provided to protrude toward the side of the hoisting section at the threshold of the landing,

For this reason, the space | interval between a to-be-detected object and the wall surface of an elevator hoistway can be ensured, and malfunction of a detector can be suppressed. Therefore, according to the present invention, it is possible to reliably position the lift at a position where the threshold of the landing and the threshold of the elevation are flush with each other.

The emergency stop mechanism 20 is provided with a governor rope 25 and a governor rope 26 mounted to the ascent 4. The emergency stop mechanism 20 restrains the governor rope 26 and automatically stops the elevating vessel 4 automatically when the elevating vessel 4 or the like descends or falls by more than the rated speed due to a certain failure.

The implantation apparatus 31 is equipped with the detector 35, the to-be-detected object 36, etc. as shown in FIG. One of the detector 35 and the object to be detected 36 is provided on the threshold portion 34 of the landing 33 to protrude toward the side of the landing 4. The other side is provided at a position corresponding to one of the detector 35 and the to-be-detected body 36 provided at the threshold portion 32 of the elevator 4 and the threshold portion 34 of the landing 33. .

In addition, in the example of illustration, the detector 35 is provided in the threshold part 32 of the lifting board 4 via the mounting flange 37 etc. which were shown to FIG. The detector 35 is provided at the end of the threshold portion 32 of the lift box 4. The to-be-detected object 36 is attached to the threshold part 34 of the boarding point 33 on the hoistway 2 side, as shown to FIG. 5 thru | or FIG.

As shown in Figs. 6 and 8, the detector 35 has a light emitting portion 38 for emitting light and a light receiving portion 39 for receiving light. When the light emitted from the light emitting unit 38 is reflected by the object corresponding to the light emitting unit 38, the detector 35 receives the reflected light by the light receiving unit 39.

The light-receiving portion 39 of the detector 35 is capable of receiving light reflected by the reflecting portion 46, which will be described later, of the object to be detected 36 in the range up to the distance L1 shown in FIG. Moreover, the detector 35 is provided in the position where distance L2 between the wall surface 2a of the elevator hoistway 2 becomes longer than said distance L1.

The detector 35 is supported by the mounting flange 37 along the width direction of the lifting and lowering direction of the light emitting portion 38 emitting light and the light receiving portion 39 receiving light. .

Here, in the example of illustration, three detectors 35 are provided along the vertical direction of the lifting box 4 (that is, the lifting direction of the lifting box). Here, the three detectors 35 are called detectors 35A, 35B, and 35C in order from the one closest to the lift 4.

The mounting flange 37 is provided on the mounting portion 41 mounted on the threshold portion 32 of the lift box 4, the support portion 42 that follows the mounting portion 41, and the support portion 42. It is formed in the sheet metal shape provided with the support piece 43 which supports the detector 35 integrally.

The attaching portion 41 is attached to the lower surface of the threshold portion 32 by a bolt 44 or the like. The attaching part 41 is formed along the surface 32a which faces the threshold part 34 of the boarding point 33 of the threshold part 32, and extends downward from this surface 32a. . The support part 42 is formed so that it may bend along the side plate 14 of the elevation 4 from the edge part 41a located in the edge of the elevation 4 of the mounting part 41. As shown in FIG.

A part of the said support part 42 is cut | disconnected, and the support piece 43 is bent from the support part 42 in the direction which protrudes toward the side of the lift 4, etc. are formed. The support piece 43 supports the detector 35 so that the direction in which the light-emitting part 38 emits light and the direction in which the light-receiving part 39 receives light follow the width direction of the lifting and lowering 4.

The to-be-detected object 36 is formed in the sheet metal shape provided with the attaching part 45 and the reflecting part 46 integrally. The attaching part 45 is attached to the surface 34a which the threshold part 34 of the boarding point 33 opposes the threshold part 32 of the boarding | lifting 4. The attaching portion 45 is formed along the surface 34a and extends downward from the surface 34a.

The reflecting portion 46 has a light emitting portion 38 of the detector 35 along the side plate 14 of the lifting end 4a at the edge of the threshold portion 34 of the mounting portion 45. And bent to face the light receiving portion 39. The reflecting portion 46 reflects the light from the light emitting portion 38 of the detector 35 and guides it to the light receiving portion 39. The reflecting portion 46 is a material or member that reflects light with high efficiency, such as a metal plate having a mirror surface, plating, or the like. .

In the above-described example, since the detector 35 uses light, the reflector 46 is made of a material or a member that reflects light with high efficiency. However, when employing a detector using beams such as sound waves other than light, As the reflecting portion, a material or member that reflects sound waves with high efficiency is employed.

Thus, in this embodiment, the to-be-detected object 36 is provided in the threshold part 34 of the boarding point 33 in which the reflecting part 46 protrudes toward the side of the lifting board 4. Moreover, the to-be-detected object 36 is arrange | positioned in the position where the distance X (shown in FIG. 7) between the reflecting part 46 and the detector 35 becomes shorter than the said distance L1. And the relationship shown by following formula 1 is established between distance L1, L2, and X.

X <L1 <L2. Equation 1

Moreover, the to-be-detected object 36 is arrange | positioned in the position which has distance L3 between the reflecting part 46 and the edge 12a of a door when the open / close door 12 is opened. The to-be-detected object 36 is provided in the position which does not prevent the opening / closing of the opening / closing door 12.

Moreover, the light emitting part 38 of the detector 35, the light receiving part 39, and the reflecting part 46 of the to-be-detected object 36 are provided mutually. The conception apparatus 31 is configured to position the lift 4 at a position where the threshold portions 32 and 34 are flush with each other by using the counter 35 between the detector 35 and the object to be detected 36. . Further, the light emitting portion 38 and the light receiving portion 39 of the detector 35 of the implantation apparatus 31 and the reflecting portion 46 of the object to be detected 36 are lifted from each other along the width direction of the lifting and lowering 4. Doing.

According to this embodiment of such a configuration, it works as follows. That is, since the detector 35 and the to-be-detected object 36 are attached to each of the thresholds 32 and 34 of the lifting box 4 and the landing 33, the vertical direction along the up-down direction when constructing the elevator 1 is shown. The trouble of adjusting the positional relationship between the detector 35 and the to-be-detected object 36 can be suppressed. For this reason, the rise of the cost at the time of construction of the elevator 1 can be suppressed.

Moreover, in the concept apparatus 31, the detector 35 attached to the threshold part 32 of the lifting box 4 protrudes toward the side of the lifting box 4, and is provided. For this reason, the distance L2 between the detector 35 and the wall surface 2a of the elevator hoisting path 2 can be ensured, and the malfunction of the detector 35 can be suppressed. Therefore, it is possible to reliably position the lift 4 at a position where the threshold 34 of the landing 33 and the threshold 32 of the lift 4 are flush with each other.

The light emitting portion 38 and the light receiving portion 39 of the detector 35 of the implantation apparatus 31 and the reflecting portion 46 of the object to be detected 36 are opposed to each other along the width direction of the lifting and lowering portion 4. Therefore, the distance L2 between the detector 35 and the wall surface 2a of the elevator hoistway 2 can be ensured. For this reason, the malfunction of the detector 35 can be suppressed, and at the same time, the elevator 34 moves up and down at a position where the threshold 34 of the landing 33 and the threshold 32 of the elevator 4 are flush with each other (4). ) Can be positioned reliably.

Moreover, since the wall surface 2a of the elevator hoistway 2 is located outside the detectable range of the detector 35, malfunction can be suppressed more reliably. For this reason, it is possible to reliably position the lift 4 at a position where the threshold 34 of the landing 33 and the threshold 32 of the lift 4 are flush with each other.

The to-be-detected object 36 is provided in the position which the said reflection part 46 does not prevent opening / closing of the opening / closing door 12 of the elevating box 4. For this reason, when lifting and lowering the elevator 4 when the elevator 1 is opened and closed, the door and the object to be detected 36 are opened and closed. There is no contact with each other.

In addition, since the detector 35 includes a light emitting portion 38 and a light receiving portion 39, and the light receiving portion 39 receives light reflected by the reflecting portion 46 of the object to be detected 36, the prior art shown in FIG. Like the implantation apparatus 91 in the construction, it is not necessary to adjust the position of the detector 92 and the detection plate 94 at the time of construction. For this reason, the rise of the cost at the time of the construction of the elevator 1 can be suppressed further.

Moreover, since the detectors 35A, 35B, and 35C are provided along the vertical direction of the elevating box 4 (that is, the elevating direction of the elevating box), the following functions. That is, as shown in FIG. 9, when the detectors 35A, 35B, 35C are on the reflector 46 at time T11, and all of the detectors 35A, 35B, 35C are not located on the reflector 46, the detector ( 35A, 35B, and 35C) are all off. Next, when the lift 4 descends and the detector 35C is positioned at the reflector 46 at time T12, the detectors 35A and 35B are turned off, and the detector 35c is turned on. Further, when the lift 4 descends and the detectors 35B and 35C are positioned at the reflector 46 at time T13, the detector 35A is turned off and the detectors 35B and 35C are turned on together. Further, when the lift 4 descends and the detectors 35A, 35B, and 35C are all positioned on the reflector 46 at time T14, the detectors 35A, 35B, and 35C are all turned on.

On the other hand, if the detectors 35A, 35B, 35C are below the reflector 46 at time T21, and all of the detectors 35A, 35B, 35C are not located in the reflector 46, then the detectors 35A, 35B, 35C ) Are all off. Next, when the lift 4 rises and the detector 35A is positioned at the reflector 46 at time T22, the detector 35A is turned on and the detectors 35B and 35C are turned off. Further, when the lift 4 rises and the detectors 35A and 35B are positioned at the reflector 46 at time T23, the detectors 35A and 35B are ON and the detector 35C is OFF. Further, as the lift 4 rises and all the detectors 35A, 35B, and 35C are positioned at the reflector 46 at time T24, the detectors 35A, 35B, and 35C are all turned on.

As described above, when the threshold 32 of the elevator 4 and the threshold 34 of the elevator landing 33 of the building are coplanar with each other as the lowering of the elevator 4 descends, The combination of ON and OFF of the detectors 35A, 35B, and 35C changes as in T11 to T14. In addition, when the position where the threshold part 32 of the elevator 4 and the threshold part 34 of the elevator platform of a building become the same surface mutually is made by the raise of the elevator 4, detector 35A, 35B. , 35C) turns on and off as T24 to T24.

Therefore, by detecting the time change of the combination of ON and OFF of the detectors 35A, 35B, and 35C, information indicating the relationship between the lowering and rising of the lift 4 and the positioning operation of the thresholds 32 and 34 is obtained. For example, a control system for the drive mechanism 19 or the like can be grasped, and this can be used for drive control or safe driving.

When the elevator 1 stops at the position where the threshold portions 32 and 34 are not flush with each other, for example, the elevator 1 may fall down or foreign matter may enter the elevator path 2. In order to prevent this, as shown in FIGS. 10 and 11, aprons 51 and 52 serving as protective plates may be attached to the threshold portions 32 and 34, respectively.

These aprons 51 and 52 are attached to the surfaces 32a and 34a of each of the threshold portions 34 and 34 and formed into a sheet metal shape extending downward from these surfaces 32a and 34a. It is.

In the above-described embodiment, when these aprons 51 and 52 are mounted on the threshold portions 32 and 34, the mounting flange 37 may be formed integrally with the apron 51 as shown in FIG. As shown in FIG. 11, the reflecting part 46 of the to-be-detected body 36 may be integrally formed with the apron 52. As shown in FIG.

In this case, the mounting flange 37 for mounting the detector 35 and the apron 51 are integrated with each other, and the reflecting portion 46 and the apron 52 of the object to be detected 36 are integrated with each other. Since the number of parts can be suppressed, it is possible to more reliably suppress the rise in cost.

In the embodiment, the detector 35 is mounted on the threshold 32 of the lift 4 and the object to be detected 36 is mounted on the threshold 34 of the landing 33. You may attach 35 to the threshold part 34 of the boarding point 33, and the to-be-detected object 36 may be attached to the threshold part 32 of the board | substrate 4 of lifting.

According to the present invention described above, since the detector and the to-be-detected body are provided at each threshold of the elevating box and the platform, it is possible to suppress an increase in cost during construction of the elevator.

In addition, one of the detector and the object to be mounted on the lift and the threshold of the landing is provided to protrude toward the side of the lift, so that the threshold of the landing and the threshold of the lift are elevated to the same plane. It can be surely positioned.
