Description

  The present invention relates to a guide rail for guiding a vehicle of a track system traffic system on the side of a guide rail.

  As a new means of transportation other than buses and railroads, a track system is used in which a guide rail is run with rubber wheels and guide wheels provided on both sides of the vehicle are guided by guide rails provided on the guide rail. The transportation system is known. Such an orbital transportation system is generally called a new transportation system or APM (Automated People Move).

  In each of the both sides of the guide rail of such a track-type traffic system, a plurality of guide rails are connected by connecting fittings along the traveling direction of the vehicle, and each guide rail guides at a predetermined interval. It is supported by guide rail posts installed on both sides of the rail.

  Here, a connecting metal fitting for connecting guide rails in this way is disclosed in, for example, Patent Document 1, and this connecting metal fitting is arranged on both upper and lower sides of the web of the guide rail across the joint between the guide rails. The connecting bracket and the push bolt make sure that the connecting rail is brought into surface contact with the web of the guide rail and the inner flange and the outer flange, thereby securely connecting the guide rails.

JP 2003-213603 A

However, in the connection metal fitting disclosed in Patent Document 1, although the looseness of the joint between the guide rails can be eliminated by surface contact, the adjacent guide rails are connected to each other so that the thermal expansion of the guide rails can be absorbed. They are not connected in a state where they are in contact with each other in the traveling direction, and a slight gap is provided between the guide rails. Accordingly, there is a concern that the vehicle may be shocked by the gap between the guide rails when the joint wheel passes through the joint in a state where the guide wheels are in contact with the guide rails.
In particular, when traveling along a curved portion of the track, a guide wheel disposed on the front side of the vehicle contacts the outer track of the track (the guide rail outside the curved portion), and the inner track of the track (inside the curved portion) Since the guide wheels arranged on the front side of the vehicle are in contact with the guide rails), if the guide wheels contact the joints of the inner and outer rails at the same time, The effect is even greater, which is undesirable in terms of ride comfort.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a guide rail laying method and a guide rail capable of reducing the influence of joints of the guide rail and improving riding comfort. And

In order to solve the above problems, the present invention employs the following means.
That is, the method for laying the guide rail according to the present invention is a method for laying the guide rail in the guide rail of the track-type traffic system including a pair of guide rails that respectively guide a plurality of guide wheels provided on both sides of the vehicle. A rail member preparation step of preparing a standard rail member having a predetermined length and an adjustment rail member having a length different from the standard rail member as rail members constituting the guide rail, and the pair of guide rails The standard rail member laying step for sequentially laying the standard rail member on both sides, and the standard rail member laying step are performed, and the tip of the standard rail member on both sides to be laid next is a curved portion of the guide rail. When positioned, the separation distance between the tips is such that the inner side is the rear side in the running direction with respect to the outer side of the curved portion, and Laying a determination step of determining whether the match regulating range defined by between distance, if it is determined that coincides with the regulation range by the determination step, the adjusting rail member on one side of the curved portion A guide rail laying method comprising: an adjusting rail member laying step.

  According to such a guide rail laying method, after the standard rail member is laid in the standard rail member laying step, the ends of the standard rail members positioned in the curved portion by the judging step are standard outside the curved portion of the guide rail. It is determined whether or not the distance between the tip of the rail member and the tip of the inner standard rail member is included in the restriction range. And when it is judged that the distance between the front-end | tip of an outer side standard rail member and the front-end | tip of an inner side standard rail member is contained in the said restriction | limiting range, it is length with a standard rail member in an adjustment rail member laying process. By laying the adjustment rail members having different lengths on one side of the outer side and the inner side of the curved portion, the front ends of the standard rail member and the adjustment rail member are just within the above-mentioned regulation range on the outer side and the inner side of the curved portion. Positioning can be avoided. As described above, in the present invention, by laying the rail member while making the determination with respect to the restriction range in the determination step, both the outer side and the inner side of the curved portion are simultaneously connected to the joint between the tips of the adjacent rail members. It can avoid that a guide wheel contacts.

  According to the guide rail laying method, the guide rail, and the traffic system of the present invention, it is possible to avoid that the guide wheel contacts the joint of the rail member in the guide rail at the same time on the outside and inside of the curved portion, and from the joint to the guide wheel. It is possible to reduce the influence and improve the riding comfort.

A total of eight are provided in the department.

  The guide rail 10 includes a floor base 10a on which the traveling wheels 23 of the vehicle 3 travel and a pair of guide rails 1 that respectively guide the guide wheels 21 of the vehicle 3 that are provided on both sides in the width direction. Here, in the guide rail 1, the left side in the width direction toward the traveling direction D is referred to as the left side guide rail 1 a, and the right side in the width direction toward the traveling direction D is referred to as the right side guide rail 1 b.

  Here, the guide rail 10 includes a straight portion 11 and a curved portion 12 provided continuously to the straight portion 11.

  The guide rail 1 is supported by guide rail posts 2 installed at predetermined intervals along the traveling direction D of the vehicle 3 on both sides in the width direction of the guide rail 10, and extends along the traveling direction D. A pair of members, that is, a left guide rail 1a and a right guide rail 1b.

  Each of the left guide rail 1a and the right guide rail 1b is a plurality of standard rail members 4 that are generally used rail members, and rail members that are shorter than the standard rail members 4. One adjustment rail member 5 and a seam portion (seam) 6 provided between the rail members adjacent to each other in the traveling direction D are provided.

  The standard rail member 4 is, for example, a rail member having a generally used length (12 meters in the present embodiment), for example, so that the vehicle 3 can be guided in contact with the guide wheels 21. 4 is arranged so that the surface facing the inner side in the width direction and the outer peripheral surface of the guide wheel 21 face each other. The standard rail member 4 is supported by a plurality of guide rail posts 2 at a position where it does not interfere with the joint portion 6.

  The adjustment rail member 5 is a rail member having a shorter length (less than 12 meters in this embodiment) than the standard rail member 4, and, like the standard rail member 4, comes into contact with the guide wheels 21 and moves the vehicle 3. In order to be able to guide, the surface facing the inner side in the width direction of the adjusting rail member 5 and the outer peripheral surface of the guide wheel 21 are arranged to face each other. The adjustment rail member 5 is supported by the plurality of guide rail posts 2 at a position where it does not interfere with the joint portion 6.

  Further, in the left guide rail 1a which is an outer track of the curved portion 12 at the left side portion of the guide rail 10 in the running direction D in the straight portion 11 of the guide rail 10, a plurality of standard rails are provided via the joint portion 6. The member 4 is connected in the traveling direction D.

  On the other hand, in the right side guide rail 1b which becomes the inner track of the curved portion 12 at the right side portion of the guide rail 10 toward the traveling direction D in the straight portion 11 of the guide rail 10, a plurality of standards are provided via the joint portion 6. The rail member 4 is connected, and the standard rail member 4 and the adjustment rail member 5 are connected via the joint portion 6 in front of the curved portion 12 so as not to straddle between the straight portion 11 and the curved portion 12. Has been.

Further, in the curved portion 12 of the guide rail 10, in the left side guide rail 1 a serving as an outer track at the left side portion of the guide rail 10 toward the traveling direction D, it is continuous with the standard rail member 4 of the straight portion 11. A standard rail member 4 is connected via a joint portion 6.
On the other hand, at the curved portion 12 of the guide rail 10, in the right side guide rail 1 b serving as an inner track at the right side portion of the guide rail 10 toward the traveling direction D, it is continuous with the adjustment rail member 5 of the straight portion 11. A standard rail member 4 is connected via a joint portion 6.

  Then, the distance is defined between the front guide wheel 21 facing the left guide rail 1a in the front carriage 20a in the traveling direction D and the front guide wheel 21 facing the right guide rail 1b in the rear carriage 20b. The restriction range LV is set so that the value of the distance L between the joint portion 6 of the left guide rail 1a and the joint portion 6 of the right guide rail 1b is not included.

  Here, when the vehicle 3 travels along the curved portion 12 of the guide rail 10, the front guide wheel 21 facing the left guide rail 1a in the front carriage 20a and the right guide rail 1b in the rear carriage 20b The opposing front guide wheels 21 are in contact with the left guide rail 1a and the right guide rail 1b, respectively. Therefore, the regulation range LV in the present embodiment is defined by the separation distance.

  Specifically, in the vehicle 3 of the present embodiment, the two front and rear carriages 20a and 20b each turn along the guide rail 10, so that the separation distance is increased to about 200 mm at the maximum. For this reason, the regulation range LV is set to a range including a value obtained by adding 200 mm to the minimum separation distance from the minimum separation distance.

  Further, since the guide wheel 21 has a certain size in the traveling direction D, the restriction range LV takes this size into consideration, and the lower limit is smaller than the minimum separation distance, and the upper limit is 200 mm at the minimum separation distance. It is set to be larger than the one added.

Next, the procedure of the method for laying the guide rail 1 will be described.
As shown in FIG. 2, the guide rail 1 is laid out by a rail member preparation step S1 for preparing a standard rail member 4 and an adjustment rail member 5, a standard rail member laying step S2, and a standard rail member 4 or an adjustment rail member. 5 is determined, and an adjustment rail member laying step S4 is provided.

  First, rail member preparation process S1 is implemented. That is, the standard rail member 4 having a predetermined length (12 meters in the present embodiment) and the adjustment rail member 5 having a length shorter than the standard rail member 4 (less than 12 meters in the present embodiment) are prepared.

  Next, as shown in FIG. 3, a standard rail member laying step S2 is performed. That is, the standard rail member 4 is fixed to the guide posts installed on both sides of the guide rail 10 in the width direction of the left guide rail 1a and the right guide rail 1b in the straight portion 11 of the guide rail 10, and the joint portion 6 is interposed. Then, the standard rail members 4 are sequentially laid in the traveling direction D.

  Further, as shown in FIG. 4, a determination step S3 is performed. Specifically, the next standard rail member 4 is temporarily arranged from the tip of the standard rail member 4 laid sequentially in the standard rail member laying step S2 toward the traveling direction D. At this time, the tip of the temporarily arranged standard rail member 4 is positioned on the curved portion 12 of the guide rail 10.

  And among the standard rail members 4 temporarily arranged across the curved portion 12 from the straight portion 11, the front guide wheel of the front carriage 20 a in the traveling direction D is provided at the tip of the standard rail member 4 in the left guide rail 1 a. When 21 is positioned, it is determined whether or not the front guide wheel 21 of the rear carriage 20b is positioned at the tip of the standard rail member 4 in the right guide rail 1b. More specifically, such a state means that the distance L between the front end of the standard rail member 4 in the left guide rail 1a and the front end of the standard rail member 4 in the right guide rail 1b is the front guide of the front carriage 20a. This is a state where the regulation range LV is defined by the distance between the wheel 21 and the front guide wheel 21 of the rear carriage 20b. Then, the state where the distance L matches the regulation range LV is determined as YES in the determination step S3, and the state where the distance L does not match the guide wheel distance LV is determined as NO determination in the determination step S3.

Here, the case where it is first determined YES in the determination step S3 will be described.
In this case, as shown in FIGS. 2 and 5, an adjustment rail member laying step S4 is executed subsequent to the determination step S3. That is, in the left guide rail 1a, the standard rail member 4 temporarily arranged in the determination step S3 is not laid as it is, but the adjustment rail member 5 is laid instead. And in the right guide rail 1b, the standard rail member 4 temporarily arranged by judgment process S3 is laid as it is.

Next, the case where it is determined NO in the determination step S3 will be described.
In this case, as shown in FIGS. 2 and 6, the standard rail member laying step S2 is executed following the determination step S3. That is, both the left guide rail 1a and the right guide rail 1b are installed with the standard rail member 4 temporarily arranged in the determination step S3.

  Then, in any case where YES determination or NO determination is made in the determination step S3 and the standard rail member laying step S2 or the adjustment rail member laying step S4 is performed, the process returns to the determination step S3, and the YES determination is again made. It is determined whether the determination is NO. And according to this judgment, adjustment rail member laying process S4 or standard rail member laying process S2 is carried out. As described above, the determination step S3, the standard rail member laying step S2, and the adjustment rail member laying step S4 are repeatedly performed as long as the distal end of the guide rail 1 to be laid is positioned at the curved portion 12.

  According to such a method of laying the guide rail 1, the standard rail member laying step S <b> 2, the determining step S <b> 3, and the adjusting rail member laying step S <b> 4 are repeated, so that the left guide rail 1 a in the curved portion 12 of the guide rail 10. The distance L between the joint portion 6 and the joint portion 6 of the right guide rail 1b is provided so as not to be always included in the regulation range LV.

  In particular, in the curved portion 12 of the guide rail 10, the left guide rail 1a is in contact with the front guide wheel 21 of the carriage 20a disposed on the front side of the vehicle 3, and the right guide rail 1b is in contact with the rear of the vehicle 3. The front guide wheel 21 of the carriage 20b disposed on the side is in contact with the seam 6 of the left guide rail 1a and the seam 6 of the right guide rail 1b as described above. Therefore, the guide wheels 21 facing the left guide rail 1a and the right guide rail 1b do not contact the joint portion 6 at the same time.

  Further, when the vehicle 3 travels along the curved portion 12, the carriages 20a and 20b turn along the guide rail 10, the distance between the guide wheels 21 fluctuates by about 200 mm, and the guide wheels 21 have a certain size. However, the restriction range LV is determined in consideration of these conditions in the determination step S3. For this reason, it can install reliably in the state which mutually shifted the joint parts 6 of the left guide rail 1a and the right guide rail 1b, and the simultaneous contact to the joint parts 6 on both sides of the guide wheel 21 can be avoided.

  Here, in order to cope with the thermal expansion in the traveling direction D of the guide rail 1, a gap is provided in the joint portion 6, and the standard rail member 4 and the adjustment rail member 5 are connected. When the guide wheel 21 passes through the joint portion 6 in a state where the guide wheel 21 is in contact with the guide rail 1, an impact is received by the gap position. For this reason, when the guide wheel 21 passes through the joint portion 6 simultaneously with the left guide rail 1a and the right guide rail 1b, the joint portion 6 is more greatly affected.

  In this respect, in this embodiment, since it is possible to avoid the impact at the position of the joint portion 6 from the left guide rail 1a and the right guide rail 1b at the same time, the contact of the guide wheel 21 with the joint portion 6 can be avoided. Riding comfort can be improved by reducing the influence of the generated vibration.

  In the laying method of the guide rail 1 of the present embodiment, it is possible to avoid the guide wheel 21 from passing through the joint portion 6 of the left guide rail 1a and the right guide rail 1b at the curved portion 12 of the guide rail 10 at the same time. The influence of the part 6 can be reduced and the riding comfort can be improved.

  The laying method described in this embodiment includes two laying methods. In the first method, by providing the adjustment rail member 5 in the linear portion 11, the distance L between the joint portion 6 of the left guide rail 1a and the joint portion 6 of the right guide rail 1b in the curved portion 12 is This is not included in the regulation range LV.

  As a second laying method, as shown in FIG. 7, by providing the adjustment rail member 5 on the curved portion 12, the curved portion 12 has a joint 6 between the left guide rail 1a and the right guide rail 1b. The distance L to the part 6 is not included in the regulation range LV. In the second laying method, for example, when the curved portion 12 is long and continuous, the position of the joint portion 6 is gradually shifted between the left guide rail 1a and the right guide rail 1b. It can be avoided that the joint portion 6 of the guide rail 1a and the joint portion 6 of the right guide rail 1b coincide with the regulation range LV.

The embodiment of the present invention has been described in detail above, but some design changes can be made without departing from the technical idea of the present invention.
For example, in this embodiment, the joint portion 6 is shifted by installing the adjustment rail member 5 on the right guide rail 1b. However, the adjustment rail member 5 may be provided on the left guide rail 1a to shift the joint portion 6. In this case, in the determination step S3, when the guide wheel 21 facing the right guide rail 1b in the carriage 20b on the rear side in the traveling direction D is positioned at the tip of the standard rail member 4 temporarily arranged in the right guide rail 1b, It is determined whether or not the guide wheel 21 facing the left guide rail 1a of the cart 20a is positioned at the tip of the standard rail member 4 temporarily arranged in the left guide rail 1a.

  The adjustment rail member 5 is shorter than the standard rail member 4, but may be longer than the standard rail member 4.

  Further, by laying the adjustment rail member 5 in the straight portion 11 of the guide rail 10, the position of the joint portion 6 does not coincide with the guide wheel distance LV in the straight portion 11, and also in the straight portion 11. Especially when the vehicle 3 travels while the guide wheel 21 is always in contact with the guide rail 1, the influence of the joint portion 6 can be reduced even in the straight portion 11, and the riding comfort in the straight portion 11 can be improved. It becomes.

  Further, in this embodiment, based on the separation distance between the left front guide wheel 21 in the front carriage 20a in the traveling direction D and the right front guide wheel 21 in the rear carriage 20b in the traveling direction D in the determination step S3. Thus, the regulation range LV is defined, and it is determined whether or not the distance L is included in the regulation range LV.

However, for example, when the left rear guide wheel 21 in the front carriage 20a in the traveling direction D and the right front guide wheel 21 in the rear truck 20b in the traveling direction D are in contact with the guide rail 1, this separation distance is used. May be set as the regulation range LV.
Further, the distance between the left front guide wheel 21 in the front carriage 20a in the traveling direction D and the right rear guide wheel 21 in the rear carriage 20b in the traveling direction D may be set as the regulation range LV. Further, the separation distance between the left rear guide wheel 21 in the front carriage 20a in the traveling direction D and the right rear guide wheel 21 in the rear carriage 20b in the traveling direction D may be set as the regulation range LV. And you may lay the guide rail 1 so that these several control range LV may be satisfied simultaneously. In this case, the influence of the joint portion 6 can be further avoided, leading to further improvement in riding comfort.

  Further, the regulation range LV serving as a determination reference in the determination step S3 may not have a certain size range, and may be a predetermined numerical value.
