Description

The present invention relates to a housing for accommodating a device installed on the side of a track on which a train travels, and a device assembly including the housing.

As an example of a device installed on the side of the track, a scanner of a fall detection system that detects a fallen person from a platform can be mentioned (see, for example, Patent Documents 1 and 2).
The scanner has a transmissive portion that transmits scanning light such as a laser. Below the platform, the scanner directs the orbit through the transmissive portion and emits scanning light such as a laser. If there is a fallen person within the scanning range, the scanning light is reflected by the fallen person, and the reflected light is transmitted through the transmitting portion. The scanner can detect the presence of a fallen person based on the input reflected light.

Japanese Unexamined Patent Publication No. 2014-11423 Japanese Unexamined Patent Publication No. 8-119107

Foreign matter such as dust and iron powder may be rolled up by a running train and adhere to the scanner. When the transmissive portion of the scanner is contaminated with foreign matter, the amount of light emitted from the scanning light emitted to the outside of the scanner is reduced, and the amount of reflected light entering the inside of the scanner is further reduced. Then, even if the scanning light is reflected by the fallen person, the scanner cannot recognize the input of the reflected light and cannot detect the presence of the fallen person.

Therefore, in order to operate the fall detection system continuously and stably, it is necessary to periodically clean the scanner in order to maintain or restore the performance of the scanner as part of the maintenance work. The shorter the cleaning cycle, the more complicated the maintenance work.
Such a problem also occurs in a device installed on the side of the track, where foreign matter wound up by the train is likely to adhere and requires regular cleaning to recover the performance deteriorated by dirt.

Therefore, it is an object of the present invention to save labor in the maintenance work of the device installed on the side of the track or the system equipped with the device.

The housing according to the present invention houses a device installed on the side of the track on which the train travels. The housing includes a housing body that forms a storage space for accommodating the device, and a device installation portion that is provided at a position closer to the front in the traveling direction of the train with respect to the central portion of the housing body and to which the device is mounted. ..
According to the above configuration, the device installed on the side of the track is accommodated in the accommodation space. The device can be protected by the housing body from foreign substances wound up by the train, and the adhesion of foreign substances to the device can be suppressed. It is permissible to extend the cleaning cycle of the equipment, and maintenance work is saved.

Here, in the process of diligent studies to achieve the above object, the inventor of the present invention finds that when the traveling direction of a train on a certain track is fixed to one of up and down, the side of that track. It was found that when the device was installed on the side, the device side on the "incoming line side" became more dirty than the device side on the "outgoing line side". The "entry side" is the side facing the leading car of the train approaching the device, and corresponds to the rear side in the traveling direction of the train. The "departure side" is the side facing the last vehicle of the train moving away from the device, and corresponds to the front side in the traveling direction of the train.

Further, the inventor of the present invention states that even if the device is housed in the housing, if the device is located in the center of the housing in the traveling direction of the train, the device side portion on the incoming line side is the exit line. It was found that it gets dirty more severely than the side of the device on the side.
The device installation unit was conceived based on such knowledge. The device installation unit positions the device in the accommodation space toward the center of the housing body in the direction of travel of the train. In other words, the device is accommodated in the accommodation space in a state of being offset to the outgoing line side.

The device side on the incoming line side is kept away from foreign matter that would have adhered if the device were located in the center. Therefore, the side portion of the device on the incoming line side is less likely to become dirty, and it is permissible to further lengthen the cleaning cycle of the device.
The housing body may have an opening that partially exposes the device placed in the containment space.

Due to the function of the device, the housing may not be completely sealed and may require an opening to partially expose the device. For example, if the device is a scanner for a fall detection system, an opening is required to allow the scanning and reflected light to pass through. If there is an opening, the chances of foreign matter entering the accommodation space will increase, and the chances of foreign matter adhering to the device will increase. Even in such a case, as described above, since the side portion of the device on the incoming line side is not easily soiled, it is permissible to lengthen the cleaning cycle of the device.

The housing body may have a first side wall covering the sides of the device on the rear side in the direction of travel. The opening may be formed in the first side wall.
The first side wall covers the side of the device on the rear side in the traveling direction. In other words, the first side wall covers the device side portion on the incoming line side. Therefore, the device can be protected from foreign matter that should have adhered to the device side portion on the incoming line side.

Even if the housing body has such a first side wall, it may be necessary to provide an opening in the first side wall due to the function of the device. In this case, the device side portion on the incoming line side is partially exposed through the opening of the first side wall. It is considered that the foreign matter enters the accommodation space through the opening of the first side wall while flying in the traveling direction of the train, and the chance of adhering to the device side portion on the incoming line side increases.
Even in such a case, the device is offset to the outgoing line side in the accommodation space, and the device side portion on the incoming line side is kept away from the foreign matter entering the accommodation space through the opening of the first side wall. Be done. The side of the device on the incoming line side is less likely to get dirty, and it is permissible to lengthen the cleaning cycle of the device.

The housing body may have an upper wall covering the top surface of the device.
According to the above configuration, it is possible to prevent foreign matter wound up by the train from falling and adhering to the upper surface of the device or the upper end of the side of the device. It is permissible to extend the cleaning cycle of the device even further.
The bottom of the housing body may be open.

According to the above configuration, even if a foreign substance enters the accommodation space, the foreign substance falls out of the accommodation space by its own weight. It is possible to reduce the chance that foreign matter adheres to the device after it stays and floats in the accommodation space, and the inner surface of the housing is less likely to become dirty. It is permissible to extend the cleaning cycle of the equipment and housing.
Further, if the bottom portion is open, the device can be put into the accommodation space or taken out of the accommodation space by displacing the housing body in the vertical direction relative to the apparatus. The device can be easily taken out of the accommodation space to expose the entire device, and the device can be sufficiently cleaned in this exposed state.

The device mounting portion may be configured by a mounting tool insertion hole through which a mounting tool for mounting the housing body to the device is inserted. The "mounting tool" is an element used for mounting the housing body to the device, such as a bolt, a screw, and a rivet.
According to the above configuration, by inserting the mounting tool into the mounting tool insertion hole, the position of the device in the accommodation space in the traveling direction can be easily positioned.

The device installation unit may have a position adjusting mechanism for adjusting the position of the device in the traveling direction in the accommodation space.
According to the above configuration, the position of the device in the traveling direction can be adjusted, and the device can be arranged at a position where the side portion of the device on the incoming line side is not contaminated.
The position adjusting mechanism may be provided at intervals in the traveling direction, and may be composed of a plurality of mounting tool insertion holes through which mounting tools for mounting the housing body to the device are inserted.

According to the above configuration, the position of the device can be easily adjusted by selecting which of the plurality of mounting tool insertion holes the mounting tool is to be inserted.
The position adjustment mechanism provides a first fixture insertion hole for positioning the device on one side in the traveling direction with respect to the central portion in the accommodation space, and the device on the other side in the traveling direction with respect to the central portion in the accommodation space. It may include a second fixture insertion hole for positioning.

According to the above configuration, depending on whether the traveling direction of the train on the track is up or down, the device is attached to the housing body using the first attachment insertion hole, or the second attachment is inserted. You can choose to attach it to the housing body using the holes. The device can be offset to the exit side regardless of the direction of travel of the train.
The positioning mechanism may include a central fixture insertion hole that positions the device at the center in the accommodation space.

According to the above configuration, it is permissible to place the device in the center of the housing when the train traveling on the track is both up and down. Therefore, both sides of the device can be made as hard as possible to get dirty.
The device may be a scanner that emits while deflecting the scanning light and detects an object based on the reflected light of the scanning light.

According to the above configuration, the cleaning cycle of the scanner installed on the side of the track can be shortened, and the maintenance work of the scanner can be saved.
The device assembly according to the present invention includes the above-mentioned housing and the device. The device is installed on the side of the track on which the train travels, and is accommodated in the accommodation space in front of the center of the housing body in the direction of travel of the train.

This device assembly has the same or corresponding technical features as the technical features of the housing described above. Therefore, the device can be protected by the housing body from foreign matter wound up by the train. In addition, the device side portion on the incoming line side can be kept away from foreign matter. Since the device (particularly, the side of the device on the incoming line side) is less likely to get dirty, it is permissible to lengthen the cleaning cycle of the device.

According to the present invention, it is possible to save labor in the maintenance work of the device installed on the side of the track or the system provided with the device.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same or corresponding elements are designated by the same reference numerals throughout the drawings, and duplication of detailed description is omitted.
(direction)
FIG. 1 shows a device assembly 1 according to an embodiment of the present invention as viewed from above. The "width direction" is the width direction of the track R, and is orthogonal to the vertical direction and the extending direction of the track R. The device assembly 1 is installed outward in the width direction when viewed from the track R and the train T traveling on the track R. That is, the device assembly 1 is installed on the side of the track R.

In this embodiment, the front surface of the device assembly 1 is directed to the track R. The "horizontal direction" of the device assembly 1 is orthogonal to the vertical direction and the front-back direction of the device assembly 1. In the state where the device assembly 1 is installed on the side of the track R, the front-rear direction of the device assembly 1 is substantially parallel to the width direction of the track R, and the lateral direction of the device assembly 1 is the extension of the track R. It is almost parallel to the direction.
Here, as shown in FIG. 1, in the track R on which the apparatus assembly 1 is installed, all trains T are on the "one side" (right side of the paper in FIG. 1) in the extending direction of the track R to the "other side". It is assumed that the train travels toward (the left side of the paper in FIG. 1).

The "one side" side of the device assembly 1 faces the leading vehicle of the train T approaching the device assembly 1. This "one side" (one side in the extending direction of the track R, one side in the lateral direction of the apparatus assembly 1 and the right side of the paper in FIG. 1) is the "entry side" or "rear side" in the traveling direction of the train T. It becomes. The "other side" side of the device assembly 1 faces the rearmost car of the train T moving away from the device assembly 1. This "other side" (the other side in the extending direction of the track R, the other side in the lateral direction of the apparatus assembly 1 and the left side of the paper in FIG. 1) is the "outgoing side" or "front side" in the traveling direction of the train T. It becomes.

(Scanner)
The device assembly 1 includes a device installed on the side of the track R and a housing 3 for accommodating the device. The scanner 2A installed below the platform P is a preferred example of a device housed in a housing 3 to form a device assembly 1.
The scanner 2A has a housing 10 and a transmissive portion 11. The housing 10 accommodates components of the scanner 2A, such as a light emitting unit, a deflection unit, a light receiving unit, and a detection unit (all of which are not shown in detail). The transmissive portion 11 has light transmittance and is provided on the front surface of the housing 10. The transmission portion 11 is formed in a band shape extending in the lateral direction of the scanner 2A in a front view, and is formed in an arc shape in a plan view.

The scanner 2A emits scanning light SL such as a laser at a light emitting unit in the housing 10. The scanning light SL passes through the transmission portion 11 and is emitted from the inside of the housing 10 to the outside. The scanning light SL is emitted while being deflected by the deflection portion, whereby a two-dimensional scanning range SR is formed. The deflection unit is composed of a deflector such as a galvano mirror or a polygon mirror, and an actuator that rotationally drives the deflector. The scanner 2A is installed on the side of the track R in a posture in which the front surface of the housing 10 is directed toward the track R and the scanning light SL is horizontally emitted. Therefore, the scanning range SR forms a horizontal plane.

Here, when the scanner 2A emits the scanning light SL forward, that is, when the scanning light SL is emitted in the width direction of the orbit R, the deflection angle of the scanning light SL is set to 0 degree. The scanning light SL is deflected around the center DC in a deflection range of approximately 180 degrees from a deflection angle of about −90 degrees to a deflection angle of about +90 degrees. The scanning light SL is emitted in the width direction from the state where it is emitted from the deflection center DC in one of the extending directions of the orbit R (the state where it is emitted at a deflection angle of about −90 degrees) in one deflection operation. (A state in which the light is ejected at a deflection angle of 0 degrees), and then a state in which the light is ejected from the deflection center DC to the other in the extending direction of the orbit R (a state in which the light is ejected at a deflection angle of about +90 degrees). , Being biased. This deflection operation is repeated at high speed by the deflection unit.

When an object exists in the scanning range SR, the scanning light SL is reflected by the object. The reflected light RL passes through the transmitting portion 11 and enters the inside from the outside of the housing 10. The light receiving unit receives the reflected light RL inside the housing 10. When the reflected light RL of a predetermined amount or more is received, the detection unit detects that an object exists in the scanning range SR.
For example, the scanner 2A may be used to detect the presence or absence of a fallen person from platform P. The scanner 2A may be used to detect the presence or absence of the vehicle C of the train T traveling on the track R. The scanner 2A may be used to detect the stop of the wheel W of the train T traveling on the track R.

The deflection center DC of the scanning light SL is located at substantially the same position as the center of the arc-shaped transmission portion 11 in a plan view. The transmission portion 11 is formed in a semicircular shape in a plan view so as to match the deflection range of the scanning light SL. One end of the transmissive portion 11 is provided on the first side surface of one side of the housing 10. The other end of the transmission portion 11 is provided on the second side surface opposite to the first side surface in the lateral direction. The scanning light SL passes through one end of the transmission portion 11 at the initial stage of the deflection operation, and passes through the other end portion of the transmission portion 11 at the end of the deflection operation.
With the front surface of the housing 10 oriented in the width direction, the first side surface is directed to one side in the extending direction of the track R, and the second side surface is directed to the other side in the extending direction of the track R. .. In other words, the first side surface is directed to the entry side or the rear side in the traveling direction of the train T, and the second side surface is directed to the exit side or the front side in the traveling direction of the train T.

(housing)
FIG. 2A is a plan sectional view of the apparatus assembly 1, and FIG. 2B is a front sectional view of the apparatus assembly 1. With reference to FIGS. 2A and 2B, the housing 3 houses the scanner 2A and protects the scanner 2A from foreign matter 90. The housing 3 includes a housing main body 21 that forms an accommodation space 20 for accommodating the scanner 2A, and a device installation portion 22 to which the scanner 2A is attached.

The housing body 21 has a front wall 23, a first side wall 24, a second side wall 25, and an upper wall 26. The accommodation space 20 is formed so as to be surrounded by the inner surfaces of these walls 23 to 26. In this embodiment, the housing body 21 does not have a bottom wall and a rear wall. The housing body 21 and the accommodation space 20 are open at the bottom and the rear.
The front wall 23 covers the front surface of the scanner 2A (housing 10). The first side wall 24 is on the incoming line side (rear side) in the traveling direction and covers one side portion (first side surface of the housing 10) of the scanner 2A. The second side wall 25 is on the outgoing line side (front side) in the traveling direction and covers the other side portion (second side surface of the housing 10) of the scanner 2A. The upper wall 26 covers the upper surface of the scanner 2A (housing 10).

In the present embodiment, the harness 13 for power supply and signal transmission / reception is connected to the upper part of the scanner 2A. The upper wall 26 has a harness passage port 27. The harness 13 is guided from the upper part of the scanner 2A to the outside of the housing 3 through the harness passage port 27.
The height of the housing body 21 is equal to or slightly larger than the height of the scanner 2A. With the upper surface of the scanner 2A covered by the upper wall 26, the lower end of the scanner 2A is positioned at the same position as or slightly above the lower edge of the front wall 23.

On the other hand, the transmissive portion 11 of the scanner 2A extends from the front surface to both side surfaces of the housing 10. The housing 3 has an opening 30 that partially exposes the scanner 2A so as not to block the scanning light SL and the reflected light RL that pass through the transmitting portion 11.
The front wall 23, the first side wall 24, and the second side wall 25 are U-shaped in a plan view. The opening 30 is continuously formed in the vertical intermediate portion of the front wall 23, the first side wall 24, and the second side wall 25, and is formed in a U shape in a plan view.

The opening 30 has a front opening 31 formed on the front wall 23 of the housing main body 21, and a first side opening 32 and a second side opening 33 continuous from the front opening 31. The first side opening 32 is continuous with one end of the front opening 31 at the front end of the first side wall 24, and extends rearward from the front end of the first side wall 24 to the middle portion in the front-rear direction. The same applies to the second side opening 33.
The front wall 23 extends laterally, and the first side wall 24 and the second side wall 25 extend in the front-rear direction. The first side wall 24 and the second side wall 25 are slightly longer than the anteroposterior dimension of the scanner 2A, whereas the front wall 23 is several times longer than the lateral dimension of the scanner 2A. The front wall 23 is longer than the first side wall 24 and the second side wall 25. The housing main body 21 and the accommodation space 20 are elongated in the lateral direction (traveling direction of the train T) of the apparatus assembly 1. Therefore, the offset arrangement described later can be realized.

The front wall 23 has a pair of tapered portions 23a and 23b in the lateral direction. Further, the front wall 23 has a central portion 23c that connects the lateral central ends of the pair of tapered portions 23a and 23b between the pair of tapered portions 23a and 23b. The tapered portions 23a and 23b are inclined toward the rear as they move away from the center in the lateral direction. The lateral outer ends of the tapered portions 23a and 23b are connected to the front ends of the side walls 24 and 25, respectively. The front ends of the side walls 24 and 25 are located rearward of the lateral center ends (and the center 23c) of the tapered portions 23a and 23b. The central portion 23c extends laterally in a plan view.

(Offset placement)
The device installation portion 22 is provided at a position closer to the front in the traveling direction of the train T with respect to the lateral central portion of the housing main body 21. The scanner 2A is attached to such a device installation unit 22. Therefore, the scanner 2A is offset to the outgoing line side in the traveling direction of the train T with respect to the lateral central portion of the housing main body 21 in the accommodation space 20.

The "offset to the outgoing line side" means that the lateral center line C2A of the scanner 2A is located closer to the front (outgoing line side) in the traveling direction than the lateral center line C3 of the housing 3. Say. The lateral center line C3 of the housing 3 may overlap with the scanner 2A in a plan view.
The device installation unit 22 is composed of a plurality of fixture insertion holes 40 through which the fixture 81 for mounting the housing body 21 to the scanner 2A is inserted. The plurality of fixture insertion holes 40 penetrate the connecting portions 28a and 28b that connect the rear ends of the first side wall 24 and the second side wall 25 of the housing body 21. The connecting portions 28a and 28b are paired up and down. The fixture insertion hole 40 is formed in both the upper connecting portion 28a and the lower connecting portion 28b.

In the present embodiment, the back side of the scanner 2A (including the back side of the housing 10 itself and the members arranged on the back side of the housing 10 to support the scanner 2A) has four fittings 81. It is attached to the device installation unit 22 at four points, up, down, left and right. That is, the four fixtures 81 are placed in the two fixture insertion holes 40 laterally separated by the upper connecting portion 28a and the two fixture insertion holes 40 laterally separated by the lower connecting portion 28b, respectively. It will be inserted later. A fixture engagement hole (not shown) with which the fixture 81 engages is provided on the back surface side of the scanner 2A. The four fixtures 81 are later inserted into the fixture engagement holes on the back side of the scanner 2A. As a result, the housing main body 21 is attached to the scanner 2A via the connecting portions 28a and 28b.

The fixture 81 may be any element as long as it is an element for attaching the two members to each other, such as bolts, screws, and rivets.
Here, when the train T travels, foreign matter 90 such as dust and iron powder is wound up. The foreign matter 90 is likely to be blown forward in the traveling direction. Therefore, the foreign matter 90 is more likely to adhere to the side portion on the incoming line side than the side portion on the outgoing line side of the scanner 2A.

On the other hand, the transmissive portions 11 of the scanner 2A are also provided on both sides of the scanner 2A. When the foreign matter 90 adheres to the scanner 2A, the amount of light of the scanning light SL emitted from the inside of the housing 10 to the outside decreases, and the amount of light of the reflected light RL entering from the outside to the inside of the housing 10 decreases. As a result, the detection unit may not be able to detect the object. To maintain or restore the performance of the scanner 2A, the scanner 2A needs to be cleaned regularly.

According to the present embodiment, the scanner 2A installed on the side of the track R is housed in the housing space 20 of the housing 3. The scanner 2A can be protected by the housing body 21 from the foreign matter 90 wound up by the train T, and the foreign matter 90 can be suppressed from adhering to the scanner 2A.
Due to the function of the scanner 2A, the housing 3 cannot have a completely sealed structure. The housing 3 has an opening 30 that exposes a part of the scanner 2A (particularly, the transmission portion 11) so that the scanning light SL and the reflected light RL can pass through without blocking. Since the deflection range of the scanning light SL extends to approximately 180 degrees, the opening 30 is provided from the front wall 23 of the housing body 21 to the side walls 24 and 25. Therefore, the foreign matter 90 that has been blown forward may enter the accommodation space 20 via the lateral end portion of the front opening 31 and the first side opening 32.

The scanner 2A is positioned in the accommodation space 20 by the device installation unit 22 in front of the central portion of the housing main body 21 in the traveling direction of the train T. In other words, the scanner 2A is accommodated in the accommodation space 20 in a state of being offset to the outgoing line side. The side portion on the incoming line side is kept away from the foreign matter 90 that would have adhered if the scanner 2A was arranged in the central portion. Even if the foreign matter 90 enters the accommodation space 20 through the lateral end portion of the front opening 31 or the first side opening 32, the chance of the foreign matter 90 adhering to the side portion on the incoming line side can be reduced. ..

As described above, since the scanner 2A is less likely to be contaminated with the foreign matter 90, it is permissible to lengthen the cleaning cycle of the scanner 2A. It is possible to save labor in the maintenance work of the scanner 2A or a system including the scanner 2A (fall detection system, vehicle detection system or vehicle stop detection system).
The upper surface of the scanner 2A is covered with the upper wall 26. Therefore, it is possible to prevent the foreign matter 90 from falling and adhering to the upper surface of the scanner 2A or the upper ends of both side portions of the scanner 2A. The bottom of the housing body 21 is open. Therefore, even if the foreign matter 90 enters the accommodation space 20, the foreign matter 90 falls out of the accommodation space 20 by its own weight. It is possible to reduce the chance that the foreign matter 90 adheres to the scanner 2A after staying and floating in the accommodation space 20, and the inner surface of the housing 3 is less likely to be soiled. Therefore, it is permissible to further extend the cleaning cycle of the scanner 2A.

(Positioning)
With reference to FIGS. 3A to 3C, the device installation unit 22 has a position adjusting mechanism 29 for adjusting the position of the scanner 2A in the accommodation space 20 in the traveling direction. The position adjusting mechanism 29 is composed of a plurality of fixture insertion holes 40.
Also in the above description, in order to support the scanner 2A at four points on the top, bottom, left, and right, the four fitting insertion holes 40 are divided into the upper and lower connecting portions 28a and 28b. The position adjusting mechanism 29 is composed of a larger number of fitting insertion holes 40 than the minimum of four. These fitting insertion holes 40 are provided separately in the upper and lower connecting portions 28a and 28b, and are provided in the connecting portions 28a and 28b at lateral intervals.

The position adjusting mechanism 29 has a first mounting tool insertion hole 41 for positioning the scanner 2A on one side with respect to the lateral central portion in the accommodation space 20, and the position adjustment mechanism 29 with respect to the lateral central portion in the accommodation space 20. It includes a second fixture insertion hole 42 for positioning the scanner 2A on the other side, and a central fixture insertion hole 43 for positioning the scanner 2A at the center in the lateral direction in the accommodation space.
Since the scanner 2A is mounted at four points, the first mounting tool insertion holes 41 are four. The upper connecting portions 28a and 28b are provided with two first attachment insertion holes 41, and the lower connecting portions 28a and 28b are provided with two first attachment insertion holes 41. There are four second mounting tool insertion holes 42 and four central mounting tool insertion holes 43.

In the present embodiment, five fitting insertion holes 40 are arranged side by side at equal intervals in each of the upper and lower connecting portions 28a and 28b. Of the five, the central fixture insertion hole 40 is arranged on the lateral center line C3 of the housing 3.
Of the five mounting tool insertion holes 40 provided in the upper and lower connecting portions 28a and 28b, two of the mounting tool insertion hole 40 at one end and the central mounting tool insertion hole 40 are the first mounting tool insertion holes 41. Is. Of the five mounting tool insertion holes 40 provided in the upper and lower connecting portions 28a and 28b, the mounting tool insertion hole 40 at the other end and the central mounting tool insertion hole 40 are the second mounting tool insertion holes 42. Is. The central mounting tool insertion hole 40 also serves as the first mounting tool insertion hole 41 and the second mounting tool insertion hole 42, and therefore, the number of mounting tool insertion holes 40 formed in the connecting portions 28a and 28b. Has been reduced. Of the five mounting tool insertion holes 40 provided in the upper and lower connecting portions 28a and 28b, the two mounting tool insertion holes 40 adjacent to each other on both sides of the central mounting tool insertion hole 40 are the central mounting tool insertion holes 43.

In the examples of FIGS. 1 and 2 (A) and FIG. 2 (B), the train T is traveling from one side to the other. One side is the incoming line side and the other side is the outgoing line side. When the traveling direction of the train T is fixed in this direction, as shown in FIG. 3A, the four fittings 81 are inserted into the four second fitting insertion holes 42, respectively. By inserting these four fittings 81 into the back surface side of the scanner 2A, the scanner 2A is offset to the other side in the lateral direction, that is, the exit side in the traveling direction in the accommodation space 20. Therefore, as described above, the side portion on the incoming line side is less likely to become dirty.

When the train T travels from the other side to one side, one side is the exit side and the other side is the entry side. When the traveling direction of the train T is fixed in this direction, as shown in FIG. 3C, the four fittings 81 are inserted into the four first fitting insertion holes 41, respectively. By inserting these four fittings 81 into the back surface side of the scanner 2A, the scanner 2A is offset to one side in the lateral direction, that is, the exit side in the traveling direction in the accommodation space 20. Therefore, as described above, the side portion on the incoming line side is less likely to become dirty.

On the same track R, some trains T may travel from one side to the other, and some trains T may travel from the other side to one side. When the traveling direction of the train T is not fixed in this way, as shown in FIG. 3B, the four fittings 81 are inserted into the four central fitting insertion holes 43, respectively. By inserting these four fittings 81 into the back surface side of the scanner 2A, the scanner 2A is arranged in the central portion in the lateral direction in the accommodation space 20. As a result, both sides of the scanner 2A are less likely to get dirty.

As described above, according to the present embodiment, the position of the scanner 2A in the accommodation space 20 in the traveling direction can be easily positioned only by inserting the mounting tool 81 into the mounting tool insertion hole 40. The position of the scanner 2A can be easily adjusted by selecting which of the plurality of mounting tool insertion holes 40 the mounting tool 81 is to be inserted. Further, by adjusting the position, the scanner 2A can be arranged at a position where the side portion on the incoming line side is not contaminated.

By using the first fixture insertion hole 41, the scanner 2A is offset to one side in the accommodation space 20. The second fixture insertion hole 42 allows the scanner 2A to be offset to the other side in the accommodation space 20. Depending on whether one side is the incoming line side or the other side is the incoming line side, it is possible to select whether to use the first mounting tool insertion hole 41 or the second mounting tool insertion hole 42, and the scanner 2A will exit the line. Offset to the side. When the traveling direction of the train T is not fixed, the scanner 2A can be made less likely to get dirty by using the central mounting tool insertion hole 43.

In this way, both the up train and the down train are used for both the scanner 2A installed on the track R on which the up train travels and the scanner 2A installed on the track R on which the down train travels. The same common housing 3 can be applied to the scanner 2A installed on the traveling track R to form the device assembly 1. Therefore, the production efficiency of the housing 3 is improved.
With reference to FIG. 2B, a state of being offset to one side using the first fixture insertion hole 41, a state of being offset to the other side using the second fixture insertion hole 42, and a state of being offset to the other side. Three harness passage ports 27 are provided on the upper wall 26 corresponding to the three arrangement states in the state of being arranged in the central portion by using the central attachment insertion hole 43. In this case, the two harness passage ports 27 are not used for passing the harness 12. These two harness passage ports 27 may be left open or may be closed by a plug 82. The same applies to the fixture insertion hole 40 that is not used.
Hereinafter, the structure for installing the scanner 2A on the track R and the specific structure of the housing 3 will be described with reference to FIGS. 4 to 10. In the following description, as a mere example, the housing body 21 is attached to the scanner 2A using the central attachment insertion hole 43.

(Installation of scanner)
As shown in FIG. 4, the scanner 2A is positioned at a predetermined height from the track R on the side of the track R. The means for positioning the scanner 2A at a predetermined height is not particularly limited. As shown in the figure, in the case of a ballast track, the pole 91 is supported by the track R by being inserted into the ballast (crushed stone or gravel) piled up on the side of the track R. A bracket 92 is attached to the pole 91. The scanner 2A is fixed to the bracket 92. The scanner 2A is supported on the track R via the bracket 92 and the pole 91. Even when there is no ballast, the pole 91 is fixed on the track R by an appropriate fixing means.

The bracket 92 is an example of a posture adjusting mechanism for adjusting the posture of the scanner 2A with respect to the trajectory R. The bracket 92 is attached to the pole 91 so that its position in the vertical direction with respect to the pole 91 can be adjusted. The bracket 92 is attached to the pole 91 so that the posture around the axis in the width direction of the track R, the posture around the axis in the extending direction of the track R, and the posture around the axis in the vertical direction can be adjusted with respect to the pole 91. .. By adjusting the position and posture of the bracket 92 with respect to the pole 91, the height of the scanner 2A from the orbit R and the posture of the scanner 2A with respect to the orbit R can be adjusted. As a result, as described above, the front surface of the housing 10 is directed in the width direction, and the scanning light SL is emitted horizontally.

(Housing components)
FIG. 5 is a perspective view of the housing body 21 as viewed from above and from the front, and FIG. 6 is a perspective view of the housing body 21 as viewed from above and from the rear. The housing body 21 is configured by assembling the front housing member 51 and the upper housing member 52.
The material and molding method of the front housing member 51 and the upper housing member 52 are not particularly limited. The front housing member 51 and the upper housing member 52 may be molded by injection molding of a synthetic resin, or may be molded by press working of a sheet metal material. In the following, unless otherwise specified, a case where the sheet metal material is formed by press working will be described as an example.

As shown in FIGS. 5 to 7, the front housing member 51 has the above-mentioned front wall 23, the first side wall 24, and the second side wall 25. The opening 30 is also formed in the front housing member 51. Since the front wall 23, the first side wall 24 and the second side wall 25 are integrated, the opening 30 is a single component even if the opening 30 is continuous from the front wall 23 to the side walls 24 and 25. Can be provided in. The rear ends of the first side opening 32 and the second side opening 33 are located in the front-rear intermediate portion of the first side wall 24, 24. Therefore, while the front opening 31 is provided over the entire lateral direction of the front wall 23, the portion above the front opening 31 of the front wall 23 is the rear end of the first side wall 24 and the second side wall 25. Through the portion, it is continuous with the portion of the front wall 23 below the front opening 31.

When the openings 30 are divided into a plurality of parts, it is necessary to carefully align the separated openings 30 with each other in order to ensure that the scanning light SL and the reflected light RL can pass through the openings 30. .. In the present embodiment, the opening 30 is provided in a single component, and a structure in which the scanning light SL and the reflected light RL surely pass through the opening 30 can be easily realized.
A bolt insertion hole 61 is formed through the central portion of the front wall 23. Bolt insertion holes 62 and 63 are formed vertically at the rear end of the first side wall 24 and the rear end of the second side wall 25, respectively.

As shown in FIGS. 5, 6 and 8, the upper housing member 52 has the above-mentioned upper wall 26. The upper housing member 52 has a front mounting piece 64 extending downward from the leading edge of the upper wall 26 at its lateral central portion. The upper housing member 52 has a pair of side mounting pieces 65 extending downward from each of the side edges of the upper wall 26 at its rear end. The front mounting piece 64 is provided with a female screw hole 66. A female screw hole 67 is provided in each of the pair of side mounting pieces 65.

Returning to FIGS. 5 and 6, the front mounting piece 64 is abutted against the back surface of the central portion 23c, and the pair of side mounting pieces 65 are abutted against the inner surface of the first side wall 24 and the inner surface of the second side wall 25, respectively. .. In this state, the bolt (not shown) is inserted into the bolt insertion holes 61 and 62 from the outside of the housing body 21 and screwed into the corresponding female screw holes 66 and 67. As a result, the front housing member 51 and the upper housing member 52 are assembled to form the housing body 21.

The side mounting piece 65 is integrally formed with the upper wall 26 by bending the side edge of the upper wall 26 at a position closer to the center in the lateral direction by the plate thickness of the upper wall 26. Therefore, the outer surface of the side mounting piece 65 is at the same position in the lateral direction as the side edge of the upper wall 26 in a plan view. Therefore, it is possible to eliminate the clearance between the side edge of the upper wall 26 and the upper edges of the first side wall 24 and the second side wall 25.

The same applies to the front mounting piece 64. It is possible to eliminate the clearance between the leading edge of the upper wall 26 and the upper edges of the tapered portions 23a and 23b of the front wall. This can reduce the chance of foreign matter 90 entering through the clearance between the front housing member 51 and the upper housing member 52.
As shown in FIGS. 5, 6 and 8, the upper housing member 52 has the above-mentioned upper connecting portion 28a. The upper connecting portion 28a extends downward from the trailing edge of the upper wall 26. The lateral dimension of the connecting portion 28a is the same as the lateral dimension of the rear end portion of the upper wall 26. Therefore, when the upper housing member 52 is assembled to the front housing member 51, the side end faces of the connecting portion 28a come into contact with the inner surfaces of the first side wall 24 and the second side wall 25. The vertical dimension of the connecting portion 28a is large with respect to the plate thickness. Therefore, the strength of the housing body 21 is increased against the load of bending both ends in the horizontal direction in the vertical direction. Further, the strength of the housing main body 21 is increased with respect to the load compressed in the lateral direction, and the deformation of the first side wall 24 and the second side wall 25 can be suppressed.

The upper housing member 52 is provided with a harness passage port 27 that penetrates the rear end portion of the upper wall 26. The harness passage port 27 is substantially entirely formed on the upper wall 26, but the rear end portion of the harness passage port 27 extends to the upper end portion of the upper connecting portion 28a. Therefore, the harness passage port 27 has an inverted L-shaped cross section. Therefore, it is easy to handle the harness 12 (see FIGS. 2B and 4) led out of the housing 3 from the accommodation space 20 to the rear.

A harness passage port 27 is preliminarily formed on the upper wall 26 by punching. The upper wall 26 is bent at the portion where the harness passage port 27 is formed. As a result, along with the formation of the connecting portion 28a, the harness passage port 27 extending to the connecting portion 28a can be formed. Since the bending process is performed at the portion where the through port (harness passage port 27) is formed, the process can be easily performed.

With reference to FIGS. 9A and 9B, the housing 3 has a lower beam member 53 bridged between the first side wall 24 and the second side wall 25 of the housing body 21. The lower beam member 53 has the above-mentioned lower connecting portion 28b. The lower beam member 53 has a pair of mounting pieces 68 projecting rearward from both lateral edges of the lower connecting portion 28b. The pair of mounting pieces 68 are provided with female screw holes 69.

FIG. 10 is a perspective view of the device assembly 1 as viewed from below and behind. The lower beam member 53 connects the rear lower end portions of the first side wall 24 and the second side wall 25 in the lateral direction. The outer surfaces of the pair of mounting pieces 68 are in contact with the inner surface of the first side wall 24 and the inner surface of the second side wall 25, respectively. In this state, a bolt (not shown) is inserted into the bolt insertion hole 63 from the outside of the housing body 21 and screwed into the corresponding female screw hole 69.

While the housing body 21 is opened at the rear portion, a pair of upper and lower connecting portions 28a and 28b connect the rear end portions of the first side wall 24 and the second side wall 25 in the lateral direction. Therefore, it is possible to realize a robust structure while reducing the weight of the housing body 21 as much as possible.
Each bolt insertion hole 61 to 63 is formed in a stepped manner, and the inner surface side has a diameter through which the shaft portion of the bolt is inserted, and the outer surface side has a larger diameter than the inner surface side. The head of the bolt is abutted against the stepped surface of the bolt insertion holes 61 to 63, and is housed in a large diameter portion on the outer surface side. The head of the bolt is not exposed on the outer surface of the housing 3, and the aesthetic appearance of the device assembly 1 is improved.

(Assembly / disassembly)
The assembly order of the housing 3 and the assembly order of the housing 3 to the scanner 2A are not particularly limited. As an example, first, the upper housing member 52 is assembled to the front housing member 51 to form the housing body 21. Next, the lower beam member 53 is assembled to the housing main body 21, and the housing 3 is configured. On the other hand, the scanner 2A is fixed to the bracket 92. The position and orientation of the scanner 2A with respect to the orbit R are adjusted as specified.

The housing 3 is placed on the scanner 2A from above with the scanner 2A installed on the side of the track R. That is, the front wall 23 is positioned in front of the front surface of the scanner 2A, the upper and lower connecting portions 28a and 28b are positioned behind the back surface of the scanner 2A, and the first side wall 24 and the second side wall 25 scan. It is positioned laterally outward from both sides of the vessel 2A. The bottom of the housing 3 is open. The housing 3 is moved from top to bottom so that the scanner 2A passes through this open bottom. As a result, the scanner 2A is accommodated in the accommodation space 20.

On the back surface side of the scanner 2A, attachment holes (not shown) with which the attachment 81 is engaged are provided at four points on the top, bottom, left, and right. The four fitting engagement holes may be formed in the housing 10 itself of the scanner 2A, or may be formed in the bracket 92.
Four of the plurality of attachment insertion holes 40 formed in the upper and lower connecting portions 28a and 28b are four attachments according to the traveling direction of the train T on the track R on which the scanner 2A is installed. Aligned with the engagement hole in the anteroposterior direction. FIG. 10 illustrates a case where both an ascending train and a descending train travel on the track R, and four central attachment insertion holes 43 are selected from a plurality of attachment insertion holes 40. Next, the four fittings 81 are inserted into the fitting insertion holes 40 from the rear of the housing 3 and engaged with the fitting engaging holes. As a result, the scanner 2A is attached to the housing 3 in a state where the position in the lateral direction (traveling direction) with respect to the housing 3 is adjusted in the accommodation space 20. That is, the device assembly 1 capable of reducing the dirt on the scanner 2A is configured.

Since the bottom of the housing 3 is open, the housing 3 can be attached to the scanner 2A in a state where the assembly of the housing 3 is completed. Therefore, it is possible to reduce the parts assembly work at the site (side of the track R). However, if the vertical intermediate portion of the back surface of the scanner 2A protrudes rearward from the lower portion, the housing body 21 is placed on the scanner 2A from above, and then the lower beam member 53 is placed on the housing body 21. It may be attached. The upper connecting portion 28a does not have a possibility of interfering with the scanner 2A at the time of assembly, and integration with the upper housing member 52 is permitted. As a result, the number of parts of the housing 3 can be reduced.

If the harness 12 is already connected to the scanner 2A, the housing 3 may be moved from top to bottom after the harness 12 has passed through the bottom and the harness passage port 27. It is also possible to connect the harness 12 to the scanner 2A after assembling the housing 3 to the scanner 2A. The fixture insertion hole 40 and the harness passage port 27 may be left open without being used. These may be appropriately blocked with a plug.

The device assembly 1 is disassembled in the reverse procedure of the above. When the fixture 81 is removed and the housing 3 is moved upward, the scanner 2A is detached from the accommodation space 20. Even if the apparatus assembly 1 is disassembled, the position and orientation of the scanner 2A with respect to the trajectory R are not changed, and the operation of the scanner 2A is not hindered.

(cleaning)
Cleaning of the scanner 2A may be performed in this disassembled state. As with assembly, disassembly can be done easily, improving cleaning efficiency.
The opening 30 exposes the transmissive portion 11 so that the scanner 2A can perform the expected function. The opening 30 may be used as a maintenance port for accessing the scanner 2A from the outside of the housing 3 during cleaning work. For example, a cleaning tool such as a brush may be inserted into the accommodation space 20 from the outer front of the housing 3 through the opening 30, and the scanner 2A may be cleaned by the cleaning tool in the assembled state of the apparatus assembly 1.

Further, the housing body 21 and the accommodation space 20 are open at the rear. A cleaning tool may be inserted into the accommodation space 20 so as to pass between the upper and lower connecting portions 28a and 28b from the outer rear of the housing 3, and the scanner 2A may be cleaned in the assembled state of the apparatus assembly 1. It can be cleaned without disassembling and reassembling, improving cleaning efficiency.

(Modification example)
Although the embodiments of the present invention have been described so far, the above configurations can be appropriately modified, added and / or deleted within the scope of the present invention.
The position adjusting mechanism is composed of five fitting insertion holes. The number of fixture insertion holes is not particularly limited. Further, the position adjusting mechanism is composed of a plurality of fitting insertion holes, whereby the position of the scanner 2A is adjusted discretely. The position adjusting mechanism may be configured by, for example, a guide rail, or the position of the scanner 2A may be continuously adjusted. Further, the housing 3 does not have to have a position adjusting function.

Although the scanner 2A is exemplified as a device that constitutes the device assembly 1 and is housed in the housing 3, it can also be applied to a device installed on the side of the track R other than the scanner 2A.
