The railroad high-altitude lighting device of Patent Document 1 cannot illuminate a wide range because it is like illuminating the ground with a spot from a high position.

On the other hand, although the construction lighting system of Patent Document 2 can illuminate a wide range, it is equipped with a plurality of rod-shaped light source units, which complicates the configuration and is installed in a high place. It is pointed out that a support device for a light source unit such as a tripod is required for this purpose. There is room for improvement here.

In view of such circumstances, the present invention provides a temporary lighting device temporarily installed in an existing facility provided at a place where lighting is required, which has a relatively simple configuration but is installed at a high position away from the existing facility. The purpose is to make it possible to illuminate a wide area.

The present invention is a temporary lighting device temporarily installed in an existing facility provided at a place where lighting is required.
It is provided with a lighting unit, a mounting portion that is detachably attached to the existing equipment, and a support portion that is made of a long body and has a base end side attached to the mounting portion while the lighting portion is attached to the tip side.
The lighting unit is arranged at a position farther and higher than the position of the mounting unit.
The illuminating portion is made of an inflexible elongated body and includes a guide rail along the longitudinal direction.
The support portion is supported in a posture in which the longitudinal direction of the illumination portion is orthogonal to the longitudinal direction thereof, and the illumination portion is supported in a posture in which the light emitted from the support portion is directed downward.
The lighting portion is fixed to the tip of the support portion via bolts and nuts engaged in the guide rail.
A flexible power cable connected to a power source is provided on one end side in the longitudinal direction of the lighting unit.
A flexible connecting cable is provided on the other end side of the lighting unit in the longitudinal direction so that it can be connected to another lighting unit having the same specifications as the lighting unit .
The guide rail is characterized in that it is provided from one end side in the longitudinal direction in which the power cable is provided to the other end side in the longitudinal direction in which the connecting cable is provided.

The temporary lighting device having this configuration is configured to install the lighting unit at a position farther and higher than the position of the mounting portion by using existing equipment such as a support column.

As a result, unlike the above-mentioned Patent Document 2, a support device such as a tripod is not required. It can be installed in a high position. Further, since a long lighting unit is used, it is possible to illuminate a wide range as compared with Patent Document 1.

In Toko filtration, in the temporary lighting apparatus, the support part, the are from the mounting portion mounted to the mounting portion obliquely upward and ing posture, it is preferable.

Here, a configuration for installing the lighting unit at a position distant from the position of the mounting unit and at a higher position is specified.

Further, in the temporary lighting device, it is preferable that the support portion is formed so as to be expandable and contractible in the longitudinal direction thereof, and the expansion and contraction operation can be performed in the support portion closer to the mounting portion. ..

In this configuration, even when the support portion to which the lighting portion is mounted is attached to the mounting portion, the expansion / contraction operation of the support portion can be performed relatively easily.

Further, in the temporary lighting device, the existing equipment is a support column, and the mounting portion is a first semi-cylindrical member and a second semi-cylindrical member that are applied to the outer peripheral surface of the support column so as to sandwich the support from the outer diameter side. Each of the semi-cylindrical member, the first semi-cylindrical member, and the second semi-cylindrical member attached to each opposite side portion of the first semi-cylindrical member and the second semi-cylindrical member. On the other hand, a hinge for displacement in a closed state in which the opposite side portions are brought close to each other to form a cylinder and an open state in which the opposite side portions are separated from each other, and a locking provided separately for each of the opposite side portions and for locking in the closed state. Each of the opposite side portions, including the portion and the locked portion, has a shape that projects outward in the radial direction and is overlapped in the closed state. It is preferable that a hinge is attached.

Here, since the first semi-cylindrical member and the second semi-cylindrical member constituting the mounting portion are mounted so as to sandwich an existing facility such as a support column, the mounting work of the mounting portion to the support column is performed. It becomes clear that it will be relatively easy to do.

Generally, for example, in the vicinity of a railroad track, columns are installed at regular intervals, for example. It is possible to use this support as an existing facility. Here, for example, when inspecting or repairing the railroad track, the temporary lighting device according to the present invention is attached to a support column installed in the vicinity of the railroad track so as not to interfere with the inspection or repair worker. Since it is possible to illuminate the railroad track from a high position, the work can be performed efficiently.

Although the temporary lighting device according to the present invention has a simpler configuration than Patent Document 2, the lighting unit can be installed at a position farther and higher than the position of the existing equipment. It becomes possible to illuminate a wide range as compared with the above-mentioned Patent Document 1.

The lock pin 45c is attached to the free end of a string-shaped member 46 such as a chain so as not to be lost in the removed state. The base end of the string-shaped member 46 is fixed to the holding plate 45a.

As shown in FIGS. 1 to 4 and 16, the support portion 5 has a long body and has a telescopic structure in which the support portion 5 is stretchably formed in the longitudinal direction.

The outer shape of the support portion 5 is a round bar shape, and although it is not shown in detail, it has a configuration in which a large number of cylindrical inner cylinders are concentrically stacked and stored in the cylindrical outer cylinder. It has become.

The base end side of the support portion 5 is inserted into the receiving portion 45 of the mounting portion 4, and a large number of inner cylinders (not shown) are taken in and out on the tip end side of the outer cylinder of the support portion 5. By doing so, it can be expanded and contracted.

The overall length of the outer cylinder and the inner cylinder of the support portion 5 is set as short as possible. Specifically, the overall length of the outer cylinder and the inner cylinder of the support portion 5 is set to, for example, about the length of an arm that can reach the tip end side of the support portion 5 from the mounting portion 4. As a result, the expansion / contraction operation of the support portion 5 can be performed relatively easily at a position close to the mounting portion 4 (the tip end side of the outer cylinder).

Further, the support portion 5 is adapted to support the illumination portion 3 in a posture in which the longitudinal direction of the illumination portion 3 is orthogonal to the longitudinal direction thereof and in a posture in which the light emitted from the support portion 3 is directed downward.

By supporting the illumination unit 3 with such a support unit 5, the illumination unit 3 is arranged at a position farther and higher than the position of the attachment unit 4.

On the tip end side of the support portion 5, as shown in FIGS. 7 to 9, a chuck plate 51 for holding the illumination portion 3 detachably and two for fixing the illumination portion 3 to the chuck plate 51. A pair of fastening units 52 is provided.

Bolt insertion holes 51a penetrating in the plate thickness direction are provided near both ends of the flat surface portion of the chuck plate 51 on the tip end side. The fastening unit 52 includes a bolt 52a, a locking nut 52b, a spring washer 52c, and a flat washer 52d.

Next, a method of using the temporary lighting device 2 described above will be described.

First, the mounting portion 4 is mounted on the support column 1. At this time, the first semi-cylindrical member 41 of the mounting portion 4 is first applied so as to sandwich the support column 1 as shown in FIG. 11, and the second semi-cylindrical member 42 is brought close to the first semi-cylindrical member 41. As a result, as shown in FIG. 10, both semi-cylindrical members 41 and 42 are placed in a closed state, and then this closed state is held by the lock unit 44.

Next, the illumination unit 3 is attached to the chuck plate 51 of the support unit 5. At this time, the fastening unit 52 is temporarily fastened to the bolt insertion hole 51a of the chuck plate 51, and the head of the bolt 52a of the fastening unit 52 is engaged with the guide rail 32 of the lighting unit 3, and then the chuck plate The 51 is positioned so as to be arranged substantially at the center position in the longitudinal direction of the illumination unit 3, and the locking nut 52b is finally tightened to the bolt 52a via the spring washer 52c and the flat washer 52d to the support portion 5. The lighting unit 3 is fixed.

After that, the receiving portion 45 of the mounting portion 4 fixed to the support column 1 as described above is placed in an appropriate inclined posture, and then the base end side of the support portion 5 to which the lighting portion 3 is mounted as described above is set to the mounting portion 4. It is inserted into the receiving portion 45.

Then, the power cable 6 of the lighting unit 3 is connected to the cable 8a of the power supply 8. When one temporary lighting device 2 is used, the cable 8a of the power supply 8 is made to run along the tip side of the support column 1 and the support portion 5, and the tip side of the power cable 6 is suspended. By suspending the power cable 6 and the cable 8a of the power supply 8 from the chuck plate 51 of the support portion 5 at 9, the power cable 6 and the cable 8a of the power supply 8 do not hang down and get in the way. Further, when the connecting cable 7 of the lighting unit 3 is not used, the tip side of the connecting cable 7 can be bundled by the tape 10 so that the connecting cable 7 does not hang down and get in the way.

Here, as shown in FIG. 4, even when only a small number of the inner cylinders are pulled out from the outer cylinder of the support portion 5, the lighting portion 3 is arranged at a position away from the support column 1 and at a high position. .. However, as shown in FIG. 3, when all the inner cylinders are pulled out from the outer cylinder of the support portion 5, the lighting portion 3 is located further away from the support column 1 and higher than that of FIG. Will be placed in. By changing the number of pulling out the inner cylinder from the outer cylinder in this way, the total length dimension of the support portion 5 can be arbitrarily adjusted.

In the installation state shown in FIG. 3, the shadows of the worker and the article are formed substantially directly below, so that the shadows are less likely to overlap the work place. On the other hand, in the installation state shown in FIG. 4, light is emitted diagonally downward from the lighting unit 3, so that if another worker or an article is positioned in the middle of the light, their shadows may overlap the work place. It can happen.

From this, it can be said that the installation state shown in FIG. 3 is easier to work than the installation state shown in FIG.

In addition, after installing one temporary lighting device 2 on the support column 1 as described above, for example, as shown in FIG. 5, the other temporary lighting devices 2 are connected to the existing temporary lighting device 2 so as to be arranged side by side in a row. can do.

At this time, it is only necessary to connect the connector 6a of the power cable 6 of the other temporary lighting device 2 to the connector 7a of the connecting cable 7 of the existing temporary lighting device 2. If the power cable 6 and the connecting cable 7 are hung down, the connector 6a of the power cable 6 and the connector 7a of the connecting cable 7 can be arranged within the reach of the operator. Connection work and disconnection work can be done relatively easily.

By the way, when the temporary lighting device 2 installed as described above is removed, the above operation may be performed in reverse.

As described above, according to the embodiment to which the present invention is applied, for example, the lighting unit 3 is installed at a position farther and higher than the position of the mounting unit 4 by using the support column 1 as the existing equipment. It is configured.

As a result, unlike the above-mentioned Patent Document 2, a support device such as a tripod is not required. It can be installed in a high position. Further, since the long illumination unit 3 is used, it is possible to illuminate a wide range as compared with the above-mentioned Patent Document 1.

In particular, if the pillar 1 as the existing equipment is used as a pillar installed at regular intervals, for example, in the vicinity of the railroad track, and the temporary lighting device 2 according to the present invention is attached to the pillar, the railroad track can be used. Since it is possible to illuminate the railroad track from a high position so as not to interfere with the inspection and repair work, the inspection and repair work can be performed efficiently.

Further, in the above embodiment, the support portion 5 to which the lighting unit 3 is mounted is attached to the mounting portion 4 by setting the overall length dimensions of the outer cylinder and the inner cylinder of the support portion 5 as short as possible. However, since the expansion / contraction operation of the support portion 5 can be performed at a position within reach, the expansion / contraction operation can be performed relatively easily.

Further, in the above embodiment, since the flexible power cable 6 is provided in the lighting unit 3 so as to protrude from the light source unit 31, the power cable 6 can be easily attached to the power supply 8. Further, in the above embodiment, since the flexible connecting cable 7 is provided in the lighting unit 3 so as to protrude from the light source unit 31, another temporary lighting device 2 having the same specifications is connected to the temporary lighting device 2 by the connecting cable 7. It makes it easier to connect. This makes it possible to illuminate as wide a range as possible with a large number of temporary lighting devices 2.

Further, in the above embodiment, since the first semi-cylindrical member 41 and the second semi-cylindrical member 42 constituting the mounting portion 4 are mounted so as to sandwich the support column 1 as the existing equipment, the support column 1 is attached. The mounting work of the mounting portion 4 can be performed relatively easily.

Further, in the above embodiment, the form is specified in which the base end side of the round bar-shaped support portion 5 is inserted into the bottomed cylindrical receiving portion 45, and the mounting posture of the support portion 5 with respect to the mounting portion 4 is various. Since it can be changed, the support portion 5 can be quickly and easily attached to the attachment portion 4, and the arrangement of the illumination portion 3 can be arbitrarily selected, which improves usability.

The present invention is not limited to the above embodiment, and can be appropriately modified within the scope of claims and within the scope equivalent to the scope.

In that case, although not shown, an adapter or the like having a rectangular cross section and a round hole is attached to the round bar-shaped column, and then the attachment portion 4 is attached to the adapter, or the attachment portion 4 is attached. It is necessary to make the inner surfaces of the first semi-cylindrical member 41 and the second semi-cylindrical member 42 into a semicircular shape.

(3) In the above embodiment, an example in which the connecting cable 7 is suspended from the lighting unit 3 by a suspending member 9 is given, but the present invention is not limited to this.

For example, although not shown, a tape with a hook-and-loop fastener can be attached to the tip end side of the connecting cable 7, and the remaining portion of the connecting cable 7 can be bundled by this tape.

Further, although not shown, a form in which a hook member is attached to the outer surface of the first semi-cylindrical member 41 or the second semi-cylindrical member 42 of the attachment portion 4 and an intermediate portion of the connecting cable 7 is hooked on the hook member. It is also possible to.

By treating the remaining portion of the connecting cable 7 in this way, it is possible to prevent the connecting cable 7 from hanging down, so that it does not interfere with the work.

Similarly, for the suspension of the power cable 6, in addition to using the suspension member 9, it is possible to use the tape with the hook-and-loop fastener as described above or the hook member as described above.

(4) Each of the parts illustrated in the above embodiment can be changed to another part having the same function.
