Linear guides 15 are provided along the vertical direction on opposite inner surfaces of a pair of side plates 14 integrally attached to both ends of the rotating shaft 9, and the pair of linear guides 15 guide both ends of the elevating body 16. The body 17 is fitted, and the elevating body 16 is attached to the pair of side plates 14 so as to be able to move up and down. The unit body C has a configuration in which a pair of side plates 14 are integrally connected by a connecting plate 18 described later.

As shown in FIGS. 4 to 6, the upper ends of the pair of side plates 14 are integrally connected by a connecting plate 18, and a mounting plate 20 is provided at a central portion of the connecting plate 18 in the longitudinal direction. Are mounted horizontally, and at the rear of the mounting plate 20,
A second drive motor M ₂ is mounted in an upright posture, and a ball screw 19 is vertically disposed in front of the drive motor M ₂ , and is rotatably supported by a bearing 21 mounted on the mounting plate 20. Have been. The ball screw 19, with screwed to the ball nut 22 mounted on the lifting body 16, a gear 23 mounted on the upper end of the ball screw 19, not the second drive motor M ₂ drive shaft (not )
Is engaged with a gear 24 attached to the gear. For this reason,
Ball screw 1 by the rotation of the drive shaft second drive motor M ₂
9 rotates, and the elevating body 16 moves up and down with respect to the pair of side plates 14.

As shown in FIGS. 4 and 5, on both sides of the ball screw 19 in the elevating body 16, two sets of two gripping pins 25 face inward. They are arranged facing each other. That is, the two sets of gripping pins 25 are respectively mounted on separate pin mounting plates 26, and each pin mounting plate 26 is laterally mounted on two guide bars 27 provided vertically on the elevating body 16. It is slidably supported. Further, a ball nut 28 attached to the base end of the pin attachment plate 26 and a ball screw 29 disposed immediately below and parallel to the two guide bars 27.
Doo is screwed, separate third through the gears 31, 32 rotation of the drive motor M ₃ are engaged with each other each ball screw 2
9, the respective ball screws 29 rotate, and the two sets of two gripping pins 25 attached to each pin mounting plate 26 approach and separate from each other. The lighting fixture D of the present embodiment includes a lifting body 16.
In this configuration, two sets of two gripping pins 25 are mounted so as to approach and separate from each other. In addition, at both ends in the longitudinal direction on the upper surface of the frame F of the exchange car B,
Are set and became two sets of stationary cylinder 33 is attached by two 2, at the time of lamp exchange, the protruding rods 33a of the fixed cylinder 33, by sandwiching both sides of the standing plate 5 of the main guide rail G ₁ , are to be fixed to the frame F with respect to the guide rails G _1.

As shown in FIG. 8, mounting plates 34 are fixed on both sides of the lamp H installed on the tunnel wall W, and two end plates are provided on the end surfaces of each mounting plate 34. A pair of first pins into which the pair of grip pins 25 are inserted.
A pin hole 35a is provided, and each mounting plate 34
A second pin hole 35b into which a fixing pin 37 provided on the bracket 36 of the installation part of the lamp H is inserted is formed through the center of the hole.

Next, after the used lamp is removed from the bracket 36, which is the lamp mounting portion of the tunnel wall W, by the leading exchange vehicle B, a new lamp H is replaced by the subsequent exchange vehicle B. To install it on the 36 part,
This is performed as follows. When to exchange the old and new lamp H is allowed to protrude the rod 33a of the fixed cylinder 33 mounted on the upper surface of the frame F of the replacement vehicle B, flanking the standing plate 5 of the main guide rail G ₁ by performed by fixing the frame F with respect to the guide rails G _1.
In the state shown in FIG. 9, the unit main body C is located at the inner rotating end, and the lamp holder D is located at the rising end with respect to the unit main body C. The first pin hole 3 provided in each of the mounting plates 34 on both sides of the lamp H
The lamp H is held by the lamp holder D as shown by a two-dot chain line in FIG.

In the above state, as shown in FIG. 10, the first drive motor M ₁ is started to move the unit main body C about the rotation shaft 9 outward (on the side approaching the tunnel wall surface W). After turning to the turning end, FIGS. 11 and 12
As shown in activates the second drive motor M _2,
When the lamp holder D is lowered with respect to the unit body C located at the outer rotating end, each of the lamps H provided on each mounting plate 34 of the lamp H held by the two sets of holding pins 25 is provided. Each fixing pin 37 fixed to the bracket 36 is inserted into the second pin hole 35b. As a result, the new lamp H is mounted on the bracket 36 mounted on the wall W of the tunnel, and the old and new lamps H are automatically replaced.

Subsequently, by activating the pair of third drive motors M ₃ , the two sets of the two holding pins 25 are separated from each other, and as shown by a solid line in FIG. From the first pin hole 35a of each mounting plate 34
5 is released, and then the lamp holder D and the unit main body C are caused to perform movements in the opposite directions to the above, so that both the lamp holder D and the unit main body C return to their original positions.
In the replacement of the lamp, the removal of the used lamp performed prior to the installation of the new lamp is performed by the same movement as when the lamp holder D and the unit main body C are returned.

In this way, even if the unit main body C rotates with respect to the frame F, or the lamp holder D moves in and out of the unit main body C, these combined trajectories are kept in the limited space. It is contained in the section S. Therefore, the shape of each frame F of the motor vehicle A and the exchange vehicle B has a substantially right triangle shape in side view, is accommodated in the limited space portion S, and has the unit body C and the lamp holder D described above. Since the combined trajectory is also contained in the limited space S, the replacement of the old and new lamps H in the limited space S can be performed without any trouble.
