Description

The present invention relates to a lighting vehicle equipped with a lighting device having a floodlight.

Conventionally, a pole-type lighting device in which a floodlight is attached to a pole that can be raised and lowered in the vertical direction is known (see, for example, Patent Document 1). There are also vehicles equipped with such a lighting device. The floodlight may be tiltably connected to the pole, or the pole may be rotatably supported.

In the pole type lighting device, the position of the floodlight can be adjusted in the vertical direction by raising and lowering the pole. In addition, the illumination range can be changed around the pole by tilting the floodlight or rotating the pole. However, the position of the floodlight cannot be adjusted horizontally. Due to these limitations, pole-type luminaires may not be suitable for certain uses. For example, even if it becomes necessary to illuminate the area below the bridge when the lighting device is placed on the bridge, it is difficult to point the floodlight at the area only by raising and lowering the pole, tilting the floodlight, and rotating the pole. be. In addition, there is room for various improvements in conventional lighting devices and lighting vehicles.

The electric power generated by the generator 130 is supplied to each floodlight 2, the tilt mechanism 4, the drive mechanism 112, and the like.

In the examples of FIGS. 1 and 2, a pair of drums 113A and 113B are attached to both side surfaces of the boom 120. A plurality of wirings 114 for connecting the generator 130 and the lighting device 1 are wound around the drums 113A and 113B. When the boom 120 is extended, the wiring 114 is sent out from the drums 113A and 113B in the direction of the lighting device 1.

For example, the operation panel 131 has buttons or switches for inputting instructions for turning, undulating and expanding and contracting the boom 120, and tilting, turning on and off of each floodlight 2. The controller 132 controls the drive mechanism 112, each floodlight 2 and the tilt mechanism 4 according to the operation of the operation panel 131.

Similarly, the plurality of connecting members 36 are arranged at both ends and the center of the vertical bars 31C and 31D in the first arrangement direction D1, for example. The rear rail 37 connects the vertical rails 31B and 31C directly or via other members such as the connecting members 35 and 36. As shown in FIG. 3, the rear rail 37 overlaps with the shafts 41A and 41B and the cross rails 30A and 30B when the lighting device 1 is viewed from the front.

As shown in FIG. 5, the frame 3 may further include a connecting member 38 inclined with respect to the vertical rail 31A and the connecting member 33. If the horizontal rail 30A and the vertical rail 31A, the horizontal rail 30A and the vertical rail 31B, the horizontal rail 30B and the vertical rail 31C, and the horizontal rail 30B and the vertical rail 31D are connected by such a connecting member 38, the strength of the frame 3 can be increased. Can be enhanced.

The floodlights 2A, 2D, 2E, and 2H are held by a pair of arms 39A extending in directions orthogonal to the first arrangement direction D1 and the second arrangement direction D2, respectively. The floodlights 2B, 2C, 2F, and 2G are each held by a pair of arms 39B extending in the first arrangement direction D1.

The base end of the arm 39A holding the floodlights 2A and 2D is fixed to the vertical rails 31A and 31B, and the tip is rotatably attached to the side portions of the floodlights 2A and 2D in the second arrangement direction D2. The base end of these arms 39A may be fixed to a connecting member 35 connecting the vertical rails 31A and 31B.

Similarly, the base end of the arm 39A holding the floodlights 2E and 2H is fixed to the vertical rails 31C and 31D, and the tip is rotatably attached to the side portion of the floodlights 2E and 2H in the second arrangement direction D2. The base end of these arms 39A may be fixed to the connecting member 36 connecting the vertical rails 31C and 31D.

As shown in FIG. 3, the base end of the arm 39B holding the floodlights 2B and 2C is fixed to the cross rail 30A, and the tip is rotatably attached to the side portion of the floodlights 2B and 2C in the second arrangement direction D2. There is.

As described above, in the examples of FIGS. 3 to 5, the floodlights 2B, 2C, 2F, 2G located on the free end side of the cross rails 30A, 30B are located on the fixed end side of the cross rails 30A, 30B. , 2D, 2E, 2H are supported by a smaller number of members. As a result, the load applied to the free end side of the cross rails 30A and 30B is reduced, so that the bending of the cross rails 30A and 30B is suppressed.

The floodlights 2A, 2D, 2E, and 2H can rotate about an axis parallel to the tilt axis TA with the attachment position of the pair of arms 39A as a fulcrum. Similarly, the floodlights 2B, 2C, 2F, and 2G can rotate about an axis parallel to the tilt axis TA with the attachment position of the pair of arms 39B as a fulcrum. In the examples of FIGS. 3 to 5, each floodlight 2 faces the same direction, but the direction of each floodlight 2 may be changed by utilizing rotation by the pair of arms 39A or the pair of arms 39B. ..

As shown in FIG. 3, the illuminating device 1 has an axisymmetric shape with respect to the tilt axis TA. Further, the illuminating device 1 has a shape that is line-symmetrical with respect to the center line C of the illuminating device 1 in the second arrangement direction D2.

That is, the distance L1 from the tilt axis TA to one end of the lighting device 1 (the ends of the floodlights 2A and 2E) in the first arrangement direction D1 and the other end of the lighting device 1 in the first arrangement direction D1 from the tilt axis TA (floodlight). The distance L2 to the end of 2D, 2H) is equal. Further, the distance L3 from the center line C to one end of the lighting device 1 in the second arrangement direction D2 (the ends of the floodlights 2B and 2C) and the other end of the lighting device 1 in the second arrangement direction D2 from the center line C (floodlight). The distance L4 to the end of 2F, 2G) is equal. In the example of FIG. 3, the distances L1 and L2 are smaller than the distances L3 and L4.

A gap G1 is formed between the floodlight 2A and the floodlight 2E. Similarly, a gap G2 is formed between the floodlight 2D and the floodlight 2H. In these gaps G1 and G2, there are no members constituting the frame 3. Further, the gaps G1 and G2 are larger than the width of the boom 120. As a result, the boom 120 can pass through the gaps G1 and G2.

Subsequently, an example of the operation of the lighting device 1 and the boom 120 will be described.
6, FIG. 7, FIGS. 8 and 9 are schematic side views of the illuminating device 1 and the boom 120. In the example of FIG. 6, the extension direction ED of the boom 120 and the first arrangement direction D1 of each floodlight 2 are horizontal (parallel to the above-mentioned XY plane). At this time, the boom 120 is located between the gaps G1 shown in FIG.

When the hydraulic cylinder 111 operates from the state of FIG. 6, the boom 120 rotates about the undulating shaft RA as shown in FIG. 7. As a result, the boom 120 undulates in the Z direction. The angle θR formed by the extension direction ED and the horizontal plane can be adjusted in a range of, for example, from 0 ° to a slightly smaller angle than 90 °.

As shown in FIG. 7, the mounting mechanism 5 of the lighting device 1 includes a first member 51 connected to the tilt machine 40 and a second member 52 connected to the tip of the boom 120. The first member 51 and the second member 52 have, for example, mounting surfaces orthogonal to the extension direction ED, and are pressed against each other by fastening bolts and nuts in a state where these mounting surfaces are in contact with each other.

When the tilt machine 40 operates, each floodlight 2 and the frame 3 rotate around the tilt axis TA. In the example of FIG. 7, each floodlight 2 is rotated clockwise until the first arrangement direction D1 is parallel to the Z direction. In the case of rotation in such a direction, the frame 3 located above the floodlight 2 in FIG. 6 does not interfere with the boom 120 even when each floodlight 2 is greatly rotated.

In the example of FIG. 8, the boom 120 undulates to θRmax, which is the maximum value of the angle θR, and extends in the extension direction ED. Each floodlight 2 is rotated by the tilt machine 40 until the floodlight direction LD becomes horizontal. At this time, the boom 120 is located between the gaps G2 shown in FIG.

The floodlight direction LD corresponds to, for example, the central axis of the range in which each floodlight 2 emits light, or the normal direction of the center point of the light emitting surface 20 of each floodlight 2. In the present embodiment, the projection direction LD is orthogonal to the first arrangement direction D1 and the second arrangement direction D2.

In the example of FIG. 9, from the state of FIG. 8, each floodlight 2 rotates counterclockwise about the tilt axis TA and faces in the direction opposite to that of FIG. As described above, each floodlight 2 can rotate at least within a range in which the rear rail 37 of the frame 3 shown in FIG. 4 does not interfere with the tilt machine 40 and the boom 120. It is preferable that each floodlight 2 can rotate within a range of 180 ° or more including a position where the floodlight direction LD of each floodlight 2 is horizontal as shown in FIGS. 8 and 9.

In the present embodiment, the tilt machine 40 includes a limit switch 42. The limit switch 42 stops the rotation of the tilt machine 40 when the angle θT formed by the first arrangement direction D1 and the extension direction ED reaches either the first limit value θ1 or the second limit value θ2.

The first limit value θ1 shown in FIG. 9 is an angle at which the boom 120 is located between the above-mentioned gaps G1 and the first arrangement direction D1 coincides with the Z direction. That is, the first limit value θ1 corresponds to 90 ° −θRmax.

The second limit value θ2 is an angle at which the boom 120 is located between the above-mentioned gaps G2 and the first arrangement direction D1 coincides with the Z direction. That is, the second limit value θ2 corresponds to 180 ° −θ1.

As an example, the maximum value θRmax is 75 °, the first limit value θ1 is 15 °, and the second limit value θ2 is 165 °. In this case, in consideration of an error, for example, the first limit value θ1 may be set to 17 ° and the second limit value θ2 may be set to 168 °.

According to the present embodiment described above, the degree of freedom in the lighting range of the lighting device 1 and the lighting vehicle 100 can be increased. That is, by turning and undulating the boom 120, and further tilting the lighting device 1, each floodlight 2 can illuminate the periphery of the lighting vehicle 100 in an extremely wide range.

The lighting vehicle 100 can also illuminate a place that was difficult with a conventional pole-type lighting device or the like. For example, if the boom 120 is extended to the side of the bridge and the light emitting direction LD of each floodlight 2 is directed downward, the lower part of the bridge can be illuminated.

Further, if the lighting device 1 can be tilted to each of the states shown in FIGS. 8 and 9, even if the turning range of the boom 120 is limited, the range of 360 ° around the lighting vehicle 100 is illuminated. Can be done.

With the structure of the lighting device 1 according to the present embodiment, the size of the lighting vehicle 100 in the standby state when no lighting is used can be made compact. That is, as shown in FIGS. 1 and 2, when the boom 120 is contracted to the maximum extent and positioned directly above the rear frame 102, and the light emitting surface 20 of each floodlight 2 is directed downward, the X direction and Y The illuminating device 1 does not protrude from other parts of the illuminating vehicle 100 in either the direction or the Z direction.

As described with reference to FIG. 3, in the present embodiment, the distance L1 from the tilt axis TA to one end of the lighting device 1 in the first arrangement direction D1 and the distance L2 to the other end are equal. In this case, even if the light emitting surface 20 of each floodlight 2 is directed in the direction opposite to that of FIG. 1 in the state where the boom 120 is tilted as shown in FIG. 1, the lighting device 1 does not protrude from the rear end 100a of the vehicle body B. ..

Further, in the present embodiment, in addition to the distances L1 and L2 being equal, the distance L3 from the center line C to one end of the lighting device 1 in the second arrangement direction D2 and the distance L4 to the other end are also equal. In this case, the lighting device 1 is supported in a well-balanced manner at the centers of the first arrangement direction D1 and the second arrangement direction D2. Therefore, the structure of the frame 3 can be simplified, and the weight of the entire lighting device 1 can be reduced. Further, the floodlight 2 having a large output and a high weight can be used because the structure of the frame 3 is simplified and the weight is reduced in this way. As an example, in the structure of the lighting device 1 according to the present embodiment, even when a medium-sized crane car is used as the base of the lighting car 100, it is possible to emit light of 10 million candelas or more in total. A heavy floodlight 2 can be used.

The above embodiments do not limit the scope of the present invention to the configurations disclosed in the embodiments. In addition, various configurations can be applied to the lighting device 1 and the lighting vehicle 100 without departing from the spirit of the present invention.
