Description

  The present invention relates to a guide wire laying structure between buildings when an automated guided vehicle travels along an electromagnetic induction guide wire laid between buildings.

  For example, Patent Document 1 shown below is an example in which an automated guided vehicle travels along a laid guide wire.

JP-A-1-194805

  In Patent Document 1, the guide wire is easily constructed without sagging, and the radio wave distortion due to sagging is prevented. However, in this patent document 1, there is no description about the laying of the guide wire between adjacent buildings, and there is no description about the technique for preventing the cutting of the guide wire in the event of an earthquake.

  Moreover, there exists patent document 2 shown below as what prevents the cutting | disconnection of the cable in the case of an earthquake, for example.

JP 2000-1975

  In the technique described in Patent Document 2, wiring is performed so as to bypass a flexible member arranged on the floor surface in the middle of a cable connected to a computer, and even when an earthquake occurs, the cable is bypassed. The cable is prevented from being cut.

  However, in the technique described in Patent Document 2, since the surface around which the cable is detoured is a horizontal plane, when this cable is used as an induction line for electromagnetic induction for running an automatic guided vehicle, The generated magnetic flux cannot be detected, and traveling becomes impossible. Also, in this Patent Document 2, there is no description about earthquake countermeasures in such a case where a guide wire for guiding and running an automated guided vehicle between adjacent buildings is laid.

  6 to 8 show a conventional configuration in which the guide wire 10 is laid on the floor surface so that the automatic guided vehicle 1 travels along the guide wire 10 between adjacent buildings (building A and building B). is there. A groove 12 is recessed in the floor 11 of the building A (building B), and the guide wire 10 is laid in the groove 12. As shown in FIGS. 6 and 8, a separation band 14 called an expansion portion is provided between the foundation 13 a of the building A and the foundation 13 b of the building B as an earthquake countermeasure between the adjacent buildings A and B. Is formed. Both foundations 13a and 13b are made of concrete. Further, a cushioning material 15 such as rubber is embedded in the separation band 14 serving as a space portion.

  A resin pipe 16 is bridged between the grooves 12 on both sides recessed in the floor 11 of the building A and the building B, and the guide wire 10 is connected between the adjacent building A and the building B through the guide wire 10 in the pipe 16. Laid. When this pipe 16 is provided, the facing portions of both the foundations 13a and 13b are deleted, the end of the pipe 16 is arranged in the deleted portion, and then the resin is filled so that the upper surface is flush with the floor surface 11. . Both ends of the pipe 16 are fixed to the foundations 13a and 13b, and the pipe 16 is disposed integrally with the foundations 13a and 13b.

  Moreover, the cut part 17 is formed in the upper part of the foundations 13a and 13b which face the isolation | separation belt | band | zone 14, The stainless steel groove cover 20 is distribute | arranged between the cut parts 17 of this both sides. The groove lid 20 is disposed on both sides of the pipe 16 so that when the automatic guided vehicle 1 travels between the buildings A and B, the tire 2 of the automatic guided vehicle 1 travels on the groove lid 20. It has become. The groove lid 20 does not simply cover the opening surface of the separation band 14 but has a considerable thickness and weight because the heavy automatic guided vehicle 1 travels on the groove lid 20.

  Thus, as shown in FIG. 6, for example, when the automated guided vehicle 1 travels from the adjacent building B to the building A, the automated guided vehicle 1 is laid on the groove 12 in the building B. 10, and further along the guide line 10 in the pipe 16 in the part of the separation zone 14. In addition, the automatic guided vehicle 1 entering the building A travels along the guide line 10 laid in the groove 12.

  Here, when an earthquake occurs, buildings A and B themselves swing back and forth, left and right, and the distance between separation zones 14 changes accordingly, and buildings A and B themselves swing individually to prevent earthquakes. Is given. However, when the separation zone 14 is widened during an earthquake, the guide wire 10 is pulled by the buildings A and B and cut along the way, and the pipe 16 also drops off from the foundations 13a and 13b. . Further, since the groove cover 20 also moves due to vibration, the pipe 16 is pressed, and the pipe 16 may be damaged or cut by the heavy groove cover 20.

  As described above, when the guide wire 10 is cut, it is necessary to find and restore the cut portion, and when the pipe 16 is broken or cut, it is also necessary to restore the original state. There is a problem that this restoration operation takes a lot of time and takes a long time to resume operation of the automatic guided vehicle 1 or the like.

The present invention has been provided in view of the above-described problems, and provides a guiding wire laying structure between buildings having at least the following objects.
(1) To prevent the guide wire from being cut by allowing the guide wire laid in the separate zone to move flexibly even if the interval of the separation zone between buildings changes during an earthquake.
(2) The pipe itself passing through the guide wire can also follow freely according to the shaking of the earthquake to prevent the pipe from being damaged or cut.
(3) Even if the groove lids arranged on both sides of the pipe move in the event of an earthquake, the movement of the groove lid to the pipe side is prevented to prevent breakage or cutting of the pipe.
(4) Even after the earthquake has stopped, recovery operation or work is unnecessary and operation can be resumed immediately.

Therefore, in the guide wire laying structure according to claim 1 of the present invention, the guide wire for guiding the transport vehicle by electromagnetic induction is laid through a pipe that bridges the separation band between adjacent buildings. In the guide wire laying structure between the buildings
The guide wire is loosened before the pipe through which the guide wire passes.

In the guiding wire laying structure between buildings according to claim 2, the guiding wire laying structure between buildings according to claim 1,
The guide wire is characterized by slacking in the vertical direction.

In the guiding wire laying structure between buildings according to claim 3, the guiding wire laying structure between buildings according to claim 1 or claim 2,
Brackets are provided on both sides of the separation band between the buildings, and the pipe is movably placed between the brackets.

In the guiding wire laying structure between buildings according to claim 4, the guiding wire laying structure between buildings according to claim 3,
The bracket is formed in a substantially L shape of a horizontal piece and a vertical piece, and forms a receiving part having an upper surface opened in the vertical piece, and the pipe is loosely fitted in the receiving part, and an end part of the pipe It is characterized by providing a collar portion for preventing falling off from the receiving portion.

  According to the guide wire laying structure between the buildings according to claim 1 of the present invention, since the guide wire is slackened in front of the pipe through which the guide wire passes, an earthquake occurs and the separation zone is front and rear, left and right Even if displaced up and down, the guide wire will not be cut.

  According to the guide wire laying structure between the buildings according to claim 2, in the guide wire laying structure between the buildings according to claim 1, the guide wire is slackened in the vertical direction. It is possible to detect the magnetic flux from the vehicle and it will not hinder the running.

  According to the guiding wire laying structure between buildings according to claim 3, in the guiding wire laying structure between buildings according to claim 1 or 2, brackets are respectively arranged on both sides of the separation band between the buildings. Since the pipe is movably placed between the brackets, even if the separation zone is displaced back and forth, left and right, and up and down in the event of an earthquake, the pipe will follow the displacement, and the pipe may be damaged. Without cutting, it is possible to prevent cutting of the guide wire. Furthermore, even if the groove lids arranged on both sides of the pipe move due to an earthquake, the groove lid hits the bracket and can press the pipe or the guide wire to prevent the pipe from being damaged or cut and the guide wire cut. .

  According to the guide wire laying structure between buildings according to claim 4, in the guide wire laying structure between buildings according to claim 3, the pipe is loosely fitted to the receiving portion of the bracket, and the end portion of the pipe By providing a hook to prevent the pipe from falling off, it is possible to prevent the pipe hook from hitting the bracket even if the pipe moves in the axial direction due to an earthquake, and preventing the pipe from dropping from the bracket. . In this way, even if an earthquake occurs, the guide wire will not be cut, nor will the pipe be damaged or cut, so when the earthquake stops, the pipe will return to its original state. This eliminates the need for restoration work after the earthquake has been settled, so that the operation can be resumed immediately.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that elements having the same functions as those in the prior art are denoted by the same reference numerals and detailed description thereof is omitted. Fig.1 (a) shows the top view of the guide wire laying structure between buildings of this invention, FIG.1 (b) has shown sectional drawing of the guide wire laying structure between buildings.

  A bracket 40 having a substantially L-shaped cross section for receiving the pipe 30 through which the guide wire 10 passes is disposed in the cut portion 17 which is one step lower than the floor surface 11 of the buildings A and B. As shown in FIG. 2, the bracket 40 is composed of a horizontal piece 41 and a vertical piece 42, and the horizontal piece 41 has holes 43 for inserting bolts on both sides. In addition, a receiving portion 44 is formed in the upper portion of the vertical piece 42 of the bracket 40 so as to be cut out in a substantially U shape and open on the upper surface. The receiving portion 44 receives the pipe 30 in a loosely fitted state. It has become.

  The brackets 40 are arranged on the cut portions 17 on both sides so that the vertical pieces 42 face each other with the vertical pieces 42 inside, and the bolts 22 (see FIG. 1) are connected to the foundations 13 a through the holes 43 of the brackets 40. The bracket 40 is fixed on the cut portion 17 by being screwed to the concrete of 13b. The outer diameter of the pipe 30 inserted from above into the receiving portion 44 of the bracket 40 is set to be considerably smaller than the inner diameter of the receiving portion 44, and the pipe 30 is loosely fitted in the receiving portion 44 relatively freely. It is arranged with.

  A flange portion 31 is integrally formed at both ends of the resin pipe 30, and the outer diameter of the flange portion 31 is larger than the inner diameter of the receiving portion 44 of the bracket 40. Thereby, even if the pipe 30 moves in the axial direction, the flange portion 31 of the pipe 30 abuts against the vertical piece 42 of the bracket 40 to prevent the pipe 30 from dropping from the receiving portion 44 (bracket 40). . The pipe 30 is entirely formed in a bellows shape, and the entire pipe 30 is flexible. Further, the groove lid 20 is arranged on both sides of the bracket 40 as in the conventional case.

  Here, passing the guide wire 10 through the pipe 30 is the same as in the prior art. However, in the present invention, as shown in FIG. A slack portion 24 in which the guide wire 10 is hung downward is provided between the two. The slack portion 24 provided before entering the pipe 30 is formed in a slackened state in the vertical direction so that the interval W between the guide wires 10 on the top of the slack portion 24 is not widened. This is to prevent the magnetic flux generated from the guide wire 10 from being reduced above the slack portion 24 and preventing the automatic guided vehicle 1 from detecting the magnetic flux as will be described later. The slack portions 24 of the guide wire 10 are provided at two locations on both sides of the pipe 30 in FIG. 1, but may be provided at least at one location on both sides of the pipe 30.

  FIG. 3 is a schematic diagram of the magnetic flux density generated in the induction wire 10. An alternating magnetic field is generated in the induction wire 10 to which an alternating current is applied, and a circle indicates the magnetic field from the top to the bottom of the drawing. It means that the magnetic field passes through from the bottom to the top of the drawing. As shown in FIG. 3, when the guide wire 10 is in a straight line state, the magnetic flux density is uniform, but one is sparse and the other is dense at a portion bent at a right angle.

  4 shows the magnetic flux density of the slack portion 24 of the guide wire 10 of the present invention, FIG. 4 (a) shows the case seen from the side, and FIG. 4 (b) is a schematic view seen from directly above. . Since the guide wire 10 is slightly spaced above the slack portion 24, the magnetic flux is small, but the guide wire 10 has a short interval (between lines), so there is no problem for the automatic guided vehicle 1 to detect the magnetic flux. The automatic guided vehicle 1 will not interfere with the traveling. On the other hand, when the interval between the guide wires 10 is increased as shown in FIG. 5, the interval (interline) between the slack portions 24 is increased and the magnetic flux becomes zero, and the automatic guided vehicle 1 cannot detect the magnetic flux and cannot run. It becomes. 5A shows a case when viewed from the side, and FIG. 5B is a schematic view when viewed from directly above.

  Here, in FIG. 1, when an earthquake occurs, the separation band 14 between the adjacent buildings A and B is displaced back and forth, left and right, up and down, but the pipe 30 is only on the receiving portion 44 of the bracket 40, The pipe 30 follows the displacement, and the pipe 30 is not damaged or cut. Moreover, since the guide wire 10 also has a surplus length at the slack portion 24 at both side portions of the pipe 30, the guide wire 10 does not cut following the displacement. Further, the groove cover 20 also tries to move due to the vibration of the earthquake, but since the end face of the groove cover 20 hits the side end face of the bracket 40, the groove cover 20 does not press the pipe 30 or the guide wire 10. Therefore, the pipe 30 is not damaged or cut, and the guide wire 10 is not cut.

  Thus, even if an earthquake occurs, the guide wire 10 is not cut, and the pipe 30 is not damaged or cut. When the earthquake stops, the pipe 30 is also shown in FIG. Return to the original state as shown. This eliminates the need for recovery work after the earthquake has been settled, so that it is possible to immediately resume operation.
