Description

  The present invention relates to a mechanical parking lot apparatus that is installed in a building having a seismic isolation structure and can detect residual displacement after an earthquake.

  In recent years, there has been an increase in seismic isolation buildings, that is, those that reduce vibration during the earthquake of the seismic isolation side structure through an anti-vibration material between the earth side structure and the seismic isolation side structure. In such a base-isolated structure building, in the earthquake, depending on the seismic intensity, a planar displacement of about 60 cm occurs between the earth-side structure and the seismic isolation-side structure. Return and restore to the original state. However, depending on the magnitude of the seismic intensity and the manner of shaking, there may be a case where the displacement in the plane direction does not return after the earthquake, and this is generally referred to as residual displacement.

  By the way, there is a type in which a mechanical parking device is installed in the seismic isolation building as described above, and in this case, the vehicle entry part of the mechanical parking device is arranged on the seismic isolation side structure, and the elevator is connected to the vehicle entry part. A lift elevating part and a vehicle storage part for elevating and lowering the pallet on the road are arranged on the earth side structure. And if it exists in the seismic isolation structure building which installed the mechanical parking apparatus and residual displacement as mentioned above will arise, the lift core of a hoistway will remain in the state which shifted | deviated. If the lift core misalignment exceeds an allowable range, a secondary disaster may occur during recovery operation.

  Therefore, it is described in Japanese Patent Application Laid-Open No. 2010-59727 (Patent Document 1) that detects whether the residual displacement between the earth-side structure and the seismic isolation-side structure exceeds a predetermined value in a non-contact manner after the earthquake. There is something. In this gazette, the housing position deviation detecting means is a photoelectric system using a light emitting / receiving photoelectric detector arranged opposite to an upper structure and a lower structure, and the light emitting / receiving photoelectric detector is photoelectric detecting It is described that a face plate having a small hole through which the optical axis of the machine passes is provided. Then, the diameter of the small hole formed in the face plate is determined based on the lift core misalignment tolerance, and the residual displacement between the earth side structure and the seismic isolation side structure when the optical axis deviates from the small hole. It is detected that the amount exceeds a predetermined value.

  However, in the above-mentioned, in order to reliably detect whether or not the residual displacement amount exceeds a predetermined value, it is necessary to form a small hole in the face plate with high accuracy, and there is a problem in terms of manufacturability. . In addition, the device has to be provided with a face plate having small holes, and there is a problem that the number of parts is relatively increased.

The present invention has been made from the above-described actual state of the prior art, and an object thereof is to provide a mechanical parking lot apparatus that can detect that the residual displacement exceeds a predetermined value with a simple structure. is there.

In order to achieve the above object, the present invention absorbs seismic motion by interposing a vibration isolator between the earth side structure and the vibration isolation side structure, and the earth side structure and the vibration isolation side structure. And a lift / lift lift that raises and lowers the pallet in a hoistway that communicates with the earth-side structure and the earth-side structure. And a vehicle storage part, and the residual displacement device is disposed in one of the earth side structure and the vibration isolation side structure, and the earth side structure and the vibration isolation side structure. In a mechanical parking lot apparatus including a photoelectric sensor having a light receiver disposed on the other side, a residual displacement amount is predetermined based on a light receiving side optical axis horizontal width that varies according to a gap dimension between the light projector and the light receiver. as characterized by detecting that the value is exceeded That.

According to the present invention, there is a small hole through which the optical axis passes as in the prior art by detecting the residual displacement based on the horizontal width of the light receiving side optical axis that fluctuates according to the gap size between the projector and the light receiver. It is not necessary to provide a face plate, and this makes it possible to detect that the amount of residual displacement exceeds a predetermined value with a simple structure. Therefore, it is possible to obtain a device with excellent manufacturability and low cost.

Here, the vibration isolator 4 is composed of seismic isolation laminated rubber, but the vibration isolator 4 may be a combination of a sliding bearing, a rolling bearing, etc., and a damper, etc., and can form a seismic isolation structure. I just need it.

  The seismic isolation building 1 is provided with a mechanical parking device 5 that can store a plurality of vehicles. The mechanical parking device 5 is an earth-side structure 2 that is the basement of the seismic isolation building 1. Are provided with a vehicle storage section 6 for storing the vehicle, and a lift hoistway section 7 disposed on the side of the vehicle storage section 6, and a vehicle entry section 8 is provided on the ground floor of the vibration isolation side structure 3. It has been.

  The vehicle storage unit 6 is configured by, for example, a two-layer horizontal circulation system, and can store a vehicle carried in via the lift elevating unit 7 in each of the lower layer storage unit 6a and the upper layer storage unit 6b.

  The lift hoistway section 7 includes a hoistway 9 that communicates with the vehicle entry section 8, a guide rail 10 that is erected on the hoistway 9, and a pallet 11 that can be raised and lowered along the guide rail 10 and on which the vehicle can be placed. An elevating body 12 for transporting between the vehicle storage unit 6 and the vehicle boarding unit 8 is provided.

  The vehicle entry portion 8 is provided with a loading / unloading port 13, and the loading / unloading port 13 is provided with a loading / unloading port door 14 that opens laterally. Further, a rectangular opening 15 in which the pallet 11 is accommodated is formed in the floor portion of the vehicle entry portion 8. In addition, the entrance / exit door 14 may open in the vertical direction.

  The guide rail 10 extends to the vicinity of the vehicle entry portion 8, and the pallet 11 is positioned at the rectangular opening 15 with the lifting body 11 at the uppermost position along the guide rail 10, and the vehicle is loaded and unloaded. Done.

  And the mechanical parking lot apparatus of this embodiment is provided with the residual displacement amount detection apparatus mentioned later in the range shown to A between the earth side structure 2 and the vibration isolation side structure 3 in FIG. Yes.

  As shown in FIGS. 1 and 2, the residual displacement detection device 16 is disposed on the vibration isolation side structure 3 so as to face the light projector 16a disposed on the earth side structure 2 and the light projector 16a. It consists of a photoelectric sensor having a light receiver 16b.

  The projector 16 a is attached to the wall surface near the upper end of the earth-side structure 2 via a bracket 17. A long hole 17 a is formed in the bracket 17, and the bracket 17 is fixed to the wall surface of the earth side structure 2 by a bolt 18 inserted through the long hole 17 a. The light receiver 16 b is attached to the wall surface near the lower end of the vibration isolation side structure 3 via a bracket 19. A long hole 19 a is formed in the bracket 19, and the bracket 19 is fixed to a wall surface of the vibration isolation side structure 3 by a bolt 20 inserted through the long hole 19 a.

  A cover 21 is disposed on the bracket 19 at a position above the light receiver 16b to prevent dust from being stacked on the light receiver 16b and the projector 16a positioned below the light receiver 16b.

  The residual displacement amount detection device 16 detects the residual displacement amount based on the light receiving side optical axis horizontal width that varies in accordance with the size of the gap between the projector 16a and the light receiver 16b. That is, the amount of residual displacement is detected using the characteristic that the light 16c emitted from the projector 16a spreads in the horizontal direction according to the distance. Specifically, for example, the light 16c emitted from the projector 16a has an optical axis horizontal width of 12 mm at a position 100 mm away from the projector 16a, but becomes an optical axis horizontal width of 16 mm when separated by 150 mm, and 20 mm when separated by 200 mm. The horizontal width of the optical axis. The light receiver 16b has a light receiving horizontal width of 1 mm, for example.

  The gap between the light projector 16a and the light receiver 16b is determined based on the allowable displacement of the lift core B of the lift hoistway section 7 shown in FIG. For example, when the allowable displacement of the lift core B of the lift hoistway section 7 is 12 mm, the predetermined amount of residual displacement between the earth-side structure 2 and the seismic isolation-side structure 3 detected by the residual displacement detection device 16 is determined. For example, the value is set to 10.5 mm. Here, the predetermined value of the residual displacement is set to 10.5 mm because the position of the lift core B of the lift hoistway section 7 is taken into account in consideration of the 1 mm horizontal light receiving width of the light receiver 16b. This is to ensure detection within the allowable value of 12 mm.

  Thus, when the predetermined value of the residual displacement amount between the earth-side structure 2 and the seismic isolation-side structure 3 is 10.5 mm, the light projector 16a and the light receiver 16b Set the gap size to 200 mm. Thus, when the projector 16a and the light receiver 16b are installed, that is, when the earth-side structure 2 and the seismic isolation-side structure 3 are opposed to each other and the horizontal shift is “0”, FIG. As shown, the light receiving side optical axis horizontal width of the light 16c irradiated by the light projector 16a, that is, the horizontal width of the light 16c corresponding to the light receiver 16b is 20 mm. On the other hand, when the earth-side structure 2 and the seismic isolation-side structure 3 are displaced in the horizontal direction due to residual displacement, and the projector 16a and the light receiver 16b are displaced in the horizontal direction by 10.5 mm or more, as shown in FIG. The light receiver 16b having a light receiving horizontal width of 1 mm cannot receive the light 16c emitted from the projector 16a, the residual displacement detector 16 is turned off, and the earth side structure 2 and the seismic isolation side structure are turned off. It is detected that the residual displacement amount with 3 exceeds a predetermined value.

  In the present embodiment, when an earthquake occurs, when a seismic intensity is detected by a seismic detector, a control device (not shown) outputs an emergency stop command and stops the mechanical parking device 5 from operating. Then, after the end of the earthquake, the residual displacement detection device 16 determines whether or not the residual displacement between the earth side structure 2 and the seismic isolation side structure 3 exceeds a predetermined value. At this time, as shown in FIG. 4, if the light projector 16a and the light receiver 16b are displaced by 10.5 mm or more in the horizontal direction, the residual displacement detection device 16 cannot obtain a light reception signal, thereby It is detected that the amount of residual displacement between the side structure 2 and the seismic isolation side structure 3 exceeds a predetermined value. By this detection, the control device holds the operation stop of the mechanical parking device 5 and monitors, for example, a notification that the residual displacement amount between the earth side structure 2 and the seismic isolation side structure 3 exceeds a predetermined value. To the center. As a result, the monitoring center arranges maintenance personnel, and the maintenance personnel visit the seismic isolation building 1 where the equipment is equipped and the residual displacement damage occurs.

According to the present embodiment, the conventional optical axis is allowed to pass through by detecting the residual displacement based on the horizontal width of the light receiving side optical axis that varies in accordance with the size of the gap between the projector 16a and the light receiver 16b. It is not necessary to provide a face plate with small holes, which makes it possible to detect that the amount of residual displacement exceeds a predetermined value with a simple structure, and therefore, it is possible to provide a device with excellent manufacturability and low cost Can do.

  Further, by arranging the projector 16a on the earth side structure 2 and the light receiver 16b on the vibration isolation side structure 3, it is possible to prevent dust from adhering to the light receiving surface of the light receiver 16b, and to detect the photoelectric sensor. High accuracy can be maintained.

  Further, by fixing the brackets 17 and 19 through the long holes 17a and 19a, the projector 16a and the light receiver 16b are surely arranged at the opposed positions at the time of installation, and the projector 16a and the light receiver 16b are horizontally arranged. It is possible to detect that the residual displacement amount between the earth side structure 2 and the seismic isolation side structure 3 exceeds a predetermined value.

  In the embodiment described above, the lift core position deviation allowable value of the lift hoistway portion 7 is 12 mm, and the residual displacement amount between the earth side structure 2 and the seismic isolation side structure 3 detected by the residual displacement amount detection device 16 is determined. The predetermined value is 10.5 mm and the gap between the projector 16a and the light receiver 16b is 200 mm. However, the present invention is not limited to this, and these values are not limited to the seismic isolation structure building 1 and the mechanical parking lot. It is arbitrarily set according to the specifications of the device 5.

  Further, while the light projector 16a is disposed on the earth side structure 2, and the light receiver 16b is disposed on the vibration isolation side structure 3, it goes without saying that the reverse is also possible.

  Furthermore, the present invention can be applied to various types of mechanical parking apparatuses such as a circular circulation type, a plane reciprocation type, and a vertical and horizontal movement puzzle type, and is not limited to the above-described embodiments.

  Further, the above-described embodiment has been described in detail for easy understanding of the present invention, and is not necessarily limited to one having all the configurations described.
