Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sensor mounting device for a mechanical parking facility. More specifically, a vertical circulation type parking facility that sequentially accommodates vehicles while circulating a plurality of vehicle accommodation pallets, or a vehicle is placed on a pallet in an entry / exit room and then moved up and down to a predetermined hangar floor. The present invention relates to a mounting device for a vehicle position confirmation sensor disposed in a parking facility or the like for moving a vehicle.
[0002]
[Prior art]
In a mechanical parking facility, a vehicle is placed on a vehicle pallet to be moved up and down and transported. When the vehicle enters the pallet, it is necessary to check whether the vehicle is within a predetermined range E on the pallet P as shown in FIG. This is to prevent a part of the vehicle M from interfering with a part of the equipment when moving up and down, and also to confirm that no person remains on the pallet P. Used. It is also necessary to check the open / closed state of the door at the entrance / exit L to the pallet.
[0003]
For such confirmation, conventionally, as shown in FIG. 5, a photoelectric sensor S or the like is provided at a predetermined height near a boundary of the predetermined range E. Thus, an accident is prevented by, for example, issuing an alarm when a part of the vehicle protrudes from a predetermined range. A plurality of sensors are provided in the height direction and the horizontal direction so as to correspond to various sizes and types of vehicles to be accommodated.
[0004]
FIG. 6 shows a conventional sensor mounting device 51.
[0005]
The sensor mounting device 51 includes a base member 52 that is fixed to the floor surface and a mounting member 53 that is telescoped into the base member 52. A fixing plate 54 inclined to correspond to the light emitting direction or the light receiving direction of the sensor S is fixed to the mounting member 53 by welding or the like, and the sensor is directed to the fixing plate 54 via a bracket 55 in a predetermined direction. It is fixed.
[0006]
Bolt holes 56 are drilled in the base member 52, and long holes 57 for position adjustment are formed in corresponding portions of the mounting member 53. By doing so, it is possible to adjust the vertical position of the attachment member 53 and thus the vertical position of the sensor S within the range of the long hole 57. Normally, the lengths of the base member 52 and the mounting member 53 are determined in advance corresponding to the vehicle type to be accommodated, and the vertical position is finely adjusted at the stage of installation.
[0007]
[Problems to be solved by the invention]
However, according to the conventional sensor mounting device 51 described above, only one sensor can be mounted at one place. If a plurality of parts are to be attached, the fixing plate 54 and the bracket 55 will have complicated shapes, and it will be difficult to attach them, so a significant increase in cost must be accepted. In addition, since the adjustment range in the vertical direction is extremely small, the orientation of the sensor is fixed, so the level of the installation surface of the sensor mounting device 51 is changed due to various factors, and the plan of the accommodation vehicle type is changed. As a result, the adjustment becomes impossible and the sensor mounting device 51 itself must be replaced.
[0008]
The present invention has been made to solve such a problem, and an object thereof is to provide a sensor mounting device for a mechanical parking facility that can easily change and adjust the mounting position of the sensor with a simple structure.
[0009]

They are calling and not used as absolute horizontal and vertical directions.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of a sensor mounting device of the present invention will be described with reference to the accompanying drawings. First, FIG. 1 (a) is a front view of the sensor mounting device 1, and FIG. 1 (b) is a side view thereof.
[0019]
In this embodiment, the support pillar 2 is installed on the floor surface F in the vertical direction. However, in the present invention, the support pillar 2 is not limited to the vertical direction, and may be a horizontal direction or an inclined direction. Further, a pipe having a circular cross section is used as the support pillar 2, but the support pillar 2 is not limited to a circular cross section. However, in the present embodiment, since the U-bolt 3 is used as a means for sandwiching the support column 2, the support column 2 preferably has a circular cross section.
[0020]
The inner radius of the U-bolt 3 is preferably substantially the same as or slightly larger than the outer radius of the support column 2. A sensor mounting bracket (hereinafter simply referred to as a bracket) 4 in which two bolt holes are drilled is attached to the U-bolt 3 with a nut 5 so as to sandwich the support column 2 with the U-bolt 3.
[0021]
As is clear from FIG. 2, the bracket 4 is composed of a horizontal plate member 6 and a vertical plate member 7. The horizontal plate member 6 is formed of a plate material having an L-shaped cross section, and the vertical portion 6a is formed with the bolt hole 6b for the U-bolt 3, and the horizontal portion 6c is bolted to the vertical plate member 7 with the bolt. Bolt holes 6d for drilling are drilled. The vertical plate member 7 is also formed of a plate material having an L-shaped cross section, and the horizontal portion 7a has a bolt hole 7b for bolting to the horizontal plate member 6, and the vertical portion 7c has a sensor S. A bolt hole 7d for pivotally supporting the sensor S and a guide hole 7e formed of an arc-shaped elongated hole for guiding the swing of the sensor S are formed.
[0022]
Four bolt holes 6d in the horizontal portion 6c of the horizontal plate member 6 are formed for adjusting the mounting position of the vertical plate member 7 in the lateral direction (arrow G in FIG. 2). Of course, six or more bolt holes 6d may be drilled so that the position can be adjusted at three or more locations. Further, instead of four or more bolt holes, a long hole in the lateral direction may be formed so that the position can be adjusted steplessly.
[0023]
One point of the sensor S is pivotably supported by a bolt 8 through a bolt hole 7d of the vertical plate member 7, and a point separated from the one point is supported by a bolt 9 through the guide hole 7e. . By doing so, the sensor is swung in the vertical direction (arrow H in FIG. 1) around the pivot point and fixed by bolting at an arbitrary angle. Thereby, the vertical direction of the light emitting part (or light receiving part) of the sensor S can be adjusted.
[0024]
Further, the nut 5 of the U-bolt 3 can be loosened to change and adjust the vertical position of the sensor S relative to the support column 2. Furthermore, since the U-bolt 3 can be rotated around the support column 2 by using the support column 2 having a circular cross section, the directivity direction of the sensor S can be changed and adjusted in the horizontal direction (arrow V in FIG. 1). . Of course, it may be possible to prevent the U-bolt 3 from rotating around the support column by using a support column having a rectangular cross section.
[0025]
As shown in FIG. 1, a plurality of sets of sensors S and brackets 4 may be attached to the support column 2 as necessary.
[0026]
A sensor mounting device 11 shown in FIG. 3 is provided with a bracket 12 (attached to the lower part of the supporting column 2) of a different form from that in FIG. The bracket 12 is attached with the bracket 4 in FIG. 1 rotated by 180 °. That is, the horizontal plate member 13 is attached to the support column 2 so that the horizontal portion 13a is downward, and the vertical plate member 14 is attached to be suspended from the lower surface of the horizontal portion 13a. Further, a plurality of sensors S are attached to the vertical portion 14 a of one vertical plate member 14. Each sensor S is adjustable in the lateral direction as in FIG. 1, and is attached so as to be swingable in the vertical direction.
[0027]
In the brackets 4 and 12 shown in FIGS. 1 to 3, the vertical plate members 7 and 14 can be moved laterally on the horizontal plate members 6 and 13 so that the position can be adjusted. It is not limited to such a structure. For example, if a plurality of types of vertical plate members 7 and 14 having different horizontal lengths are prepared and the vertical plate members 7 and 14 are selected as necessary, the lateral position of the sensor S with respect to the support column 2 can be determined. Can be changed. Moreover, instead of the bracket in which the horizontal plate member and the vertical plate member are separated as shown in FIGS. 1 to 3, a bracket in which the horizontal plate member and the vertical plate member are integrated is used in the present invention. May be. That is, a plurality of types of brackets having different horizontal mounting positions of the sensors S on the horizontal portion and different numbers of sensors S to be attached to one bracket are prepared, and the sensor can be selected by selecting a bracket according to necessity. It is possible to change the position of the S in the horizontal direction with respect to the support pillar 2 and the number of attached pieces. By doing so, fine adjustment work is omitted. In addition, by standardizing all parts of the sensor mounting device by making all the supporting columns the same thickness and the same length, making all the sizes of the U-bolts 3 and the like the same, and preparing the above-described plural types of brackets.
[0028]
Regardless of the type of bracket described above, the lateral mounting position of the sensor S can be changed as shown in FIGS. In FIG. 1, the sensor S is attached along the center line of the support column 2, in other words, the orientation direction of the sensor S is the radial direction in the cross section of the support column 2 (see FIG. 1A). . In FIG. 3, the sensor S is attached so that it is shifted laterally from the center line of the support column 2, in other words, the orientation direction of the sensor S deviates from the radial direction in the cross section of the support column 2 (FIG. 3 ( a)).
[0029]
FIG. 4 shows a sensor mounting device 21 according to a different embodiment.
[0030]
In the sensor mounting device 21, the support column 22 includes two column elements 22 a that are parallel to each other. Then, instead of the above-mentioned U-bolts, a clamping means composed of a clamping plate 23a in which a plurality of bolt holes 23b are formed side by side and two bolts 23c penetrating into the bolt holes 23b. 23 is used. The gap between the two pillar elements 22a is just the dimension through which the bolt 23c is inserted. By doing so, the clamping means 23 can be adjusted up and down in a state in which the clamping means 23 cannot rotate around the support column 22.
[0031]
The horizontal portion 25a of the horizontal plate member 25 of the bracket 24 includes a bolt hole 25b for pivotally supporting the vertical plate member 26 and an arc-shaped elongated hole for guiding the horizontal swing of the vertical plate member 26. A guide hole 25c is formed. By doing so, the vertical plate member 26 is pivotally supported by the bolt 27 so that one point of the horizontal portion 26a can swing in the horizontal direction, and the point separated from the one point is supported by the bolt 28 through the guide hole 25c. It is attached by. By doing so, the vertical plate member 26 is swung laterally around the pivot point together with the sensor, and is fixed by bolting at an arbitrary angle. Thereby, the horizontal direction of the light emitting unit (or light receiving unit) of the sensor S can be adjusted.
[0032]
The structure of the vertical plate member 26 is the same as that shown in FIGS. The bolt 23c may be protruded by being implanted in the clamping plate 23a without being separated from the clamping plate 23a.
[0033]
It is also possible to apply such a vertical plate member that can swing in the lateral direction and a corresponding horizontal plate member to the sensor mounting devices 1 and 11 shown in FIGS. In particular, it is advantageous in the case of a structure in which a U-bolt cannot rotate using a support pillar having a rectangular cross section.
[0034]
In the above embodiment, the U-bolt and the clamping means shown in FIG. 4 are used for fixing to the support column. However, the present invention is not limited to using the action of clamping for fixing. For example, a member that is inserted through the gap between the two column elements as shown in FIG. 4 and is elastically stretched between the two column elements and fixed using frictional force may be used.
[0035]
【The invention's effect】
According to the present invention, the sensor can be fixed at a desired position of the support column by moving the clamping means along the support column. In addition, the position of the sensor can be adjusted steplessly within the range of the length of the support column. Also, standardization of the sensor mounting device is possible.
