Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is a method for constructing a track for guiding an engine-driven vehicle generally called a guideway bus or an electric vehicle with rubber tires in consideration of conversion of the vehicle. It is about.

(Prior Art) The guideway bus is also referred to as a dual mode vehicle because it can travel on a general road, and is guided by guide rollers extending to the left and right sides of the vehicle body and guide rails provided on the side of the track. It is designed to run on orbit. Such a transportation system is generally referred to as a guideway bus system.

On the other hand, the electric vehicle with rubber tires is generally used in a transportation system called a new transportation system, and is driven by an electric (motor) while being guided by guide rollers and guide rails in the same way as the guideway bus. To run.

In this way, both systems are common in that the vehicle is guided by the guide rails on the track side and the guide rollers on the vehicle side.
Theoretically possible. In addition, the new transportation system has high construction costs due to the need for electrical and communication facilities over the entire line, and at the present time it is not possible to expect an early return on investment. There is a demand to reduce the initial investment by using it as a system track and switch to a new transportation system track in the future as demand increases.

However, in this case, in the guideway bus, the guide roller needs to be stored under the vehicle body so that it does not hinder traveling when traveling on general roads. In a vehicle (hereinafter referred to as a new transportation vehicle), since a branch wheel for guiding a branch portion is provided below the guide roller, the guide roller is provided at a higher position than that of the guideway bus, It is necessary to change the height position of the guide rail of the track depending on whether it will be used as a guide fabus track or a new traffic vehicle track.

In this case, in the conventional vehicle guidance track, since the guide rail is installed on the floor slab as fixed equipment with a height corresponding to the vehicle, the guideway bus system is switched to the new transportation system as described above. In doing so, the guide rail must be renewed over the entire line including the supporting equipment such as rail stanchions, and the track remodeling work will be extremely large for this rail remodeling. Therefore, the construction period is long and the construction cost is high, which is a major obstacle to system conversion.

(Object of the Invention) Therefore, the present invention is a vehicle guidance system that can efficiently perform guide rail remodeling with a minimum of labor and labor, and can shorten the period of track remodeling work associated with system conversion and reduce construction costs. It provides a track construction method.

(Structure of the Invention) The present invention is a vehicle in which a floor slab equipped with a vehicle running roadbed is provided with left and right guide rails that guide the vehicle by contacting guide rollers that are extended on both the left and right sides of the vehicle. A step construction method of a vehicle guide track for constructing a guide track so that the height position of the guide rail can be made variable so as to correspond to two types of vehicles having different height positions of the guide rollers. In the part where one of the guide rails is attached, both the high position and low position rail mounts corresponding to the above two types of vehicles are provided, and the column mount is provided in the part where the other guide rail is mounted. At the construction stage, one of the guide rails is detachably attached to the rail support member that is detachably attached to the low-position rail mount, and the other guide rail is detached to the column mount. Each of the guide rails is detachably attached to the high-position rail mount via a rail support member, and the other guide rail is removed from the low-position rail mount at the time of vehicle conversion. The guide rail of (1) is to be moved to a high position by inserting a support pedestal between the rail support and the floor slab.

With this configuration, when the track is modified due to the transition from the guideway bus system to the new transportation system, one guide rail is moved from the low position rail fixture to the high position rail fixture, and the other guide rail is moved. With regard to, by inserting the support pedestal under the rail support, it is possible to easily change the position to the position corresponding to the new vehicle. For this reason, the guide rail can be easily refurbished with a minimum of labor and labor, and the track remodeling work can be performed efficiently in a short time.

(Embodiment) FIG. 1 (a) and (b) show a first embodiment of the invention, and FIG. 2 (a).
The second embodiment is shown in (B), and the third embodiment is shown in FIGS. Further, in each of the embodiments, the case of a double track is taken as an example.

First, the parts common to each embodiment will be described. 1 is a concrete floor slab, and the floor slab 1 includes both left and right side walls 2, 2.
Left and right traveling roadbeds 3, 3 on which the vehicle travels are provided, and both side guide rails 4, 5 are provided so as to sandwich the both traveling roadbeds 3, 3. When the track is used in a guideway bus system, the guide rails 4 and 4 are guide rollers of the guideway bus B as shown in (a) of each of FIGS. 1 to 3.
When it is used in a new transportation system in a low position corresponding to B ₁ and B ₁ , it is high corresponding to the guide rollers M ₁ and M ₁ of the new transportation vehicle M as shown in each figure (b). It is installed in each position. Further, in both the first and second embodiments, the guide rail spacing (hereinafter referred to as the guide width) is also changed corresponding to the case where the guide roller spacings of the two vehicles are different. In the third embodiment, the guide roller spacing is changed. Cases in which only the rail height position is changed corresponding to the case where are equal are shown. Hereinafter, each example will be described in detail. In addition, in each embodiment, since both lines of the double track are exactly the same, only one line will be described below.

First Embodiment At the initial stage of construction of the track, anchor bolts 6 and side walls 2 as pillar support members on the track center side of the left and right sides of the traveling roadbed (hereinafter simply referred to as roadbed) 3 in the floor slab 1 are provided.
One set of anchor bolts 7 as rail attachments for low value are planted on the side, and rail posts 8 and 9 are nuts on these anchor bolts 6 and 7, respectively, as shown in enlarged view in FIG. It is removably attached with 10… and guide rails 4,5
Is detachably attached by screwing or the like. Also,
In preparation for the system conversion, a set of anchor bolts 11 as high-position rail mounts are horizontally installed in advance on the inner surface of the side wall 2. H ₁ indicates the rail height in this track condition, W ₁ indicates the guide width, and guideway bus B in this track condition
The guideways B ₁ and B ₁ on both sides of the guideway contact the guide rails 4 and 5 on both sides, and the guideway bus B travels on the roadbed 3 by the guiding action of these.

Next, when modifying the track for system conversion from the guideway bus system to the new transportation system, as shown in Fig. 1 (b),
Only the height position of the guide rail (hereinafter referred to as the inner guide rail) 4 on the center side of the roadbed can be changed at the same position in the track width direction, and the position of the other guide rail (hereinafter referred to as the outer guide rail) 5 in the track width direction. And height can be changed.

That is, at this time, the rail support 8 for the inner guide rail 4 (hereinafter referred to as the inner rail support along with the guide rail) 8 is removed from the anchor bolt 6, and the anchor bolt is used instead as shown in FIG. After mounting the column support 12 on 6 with the nut 10, the rail column 8 is mounted on the column support 12 with bolts 13a and 13b.
On the other hand, the outer rail support 9 is also removed from the anchor bolt 7, and the outer guide rail 5 removed from the outer rail support 9 is attached to the anchor bolt 11 of the side wall 2 via the support plate 13. The support plate 13 is attached to the anchor bolt 11 by nuts 14 ... As enlargedly shown in FIG. 5, and the outer guide rail 5 is fixed to the support plate 13 by rail stoppers 15 and 16.

At this time, H ₂ indicates the rail height and W ₂ indicates the guide width, and in this track state, the guide rollers M ₁ , M ₁ of the new transportation vehicle M
Contacts the guide rails 4 and 5 on both sides to perform the vehicle guidance function.

In this way, when the system is changed from the guideway bus system to the new transportation system, for the inner guide rails 4, the inner rail struts 8 and the floor slab 1 are inserted into the pedestal pedestals 12 to raise the outer guides. As for the rail 5, the guide rail can be installed with the minimum effort and labor of moving it to the anchor bolts 11 that are previously planted on the side wall 2.
The position change work of 4 and 5 can be performed easily and quickly. For this reason, it is possible to efficiently perform the track conversion work in which the rail remodeling occupies a large weight in a short period of time.

Second Embodiment In the second embodiment, contrary to the case of the first embodiment, only the height position of the outer guide rail 5 is changed, and both the height and the track width direction positions of the inner guide rail 4 are changed. I am trying to change.

That is, in the initial construction stage, three pairs of left and right anchor bolts (hereinafter referred to as column anchor bolts) 17,18,19 for mounting the rail post on the side wall of the floor slab 1 are supported on the side wall 2 in the upper and lower three sets. Anchor bolts for plate mounting (hereinafter referred to as plate anchor bolts) 20,21,22
Install at equal intervals. When initially used as a guideway bus track, the rail support 8 is first set to the inner two sets of anchor bolts 17 and 18, and the support plate 13 is first set to the lower two sets of plate anchor bolts 20 and 21, respectively. The rail support 8 is attached in the same manner as in the embodiment.
The inner guide rail 4 and the outer guide rail 5 are attached to the support plate 13 and the support plate 13, respectively.

On the other hand, at the time of conversion to the new transportation system, as shown in FIG.
The two guides are moved to the two anchor bolts for pillars 18 and 19 on the inner side in a state of being raised by 12 and the guide rails 5 for the outer guide rail 5 are moved to the two anchor bolts for plates 21 and 22 on the upper side so that both guides are supported. Relocate the rails 4,5 to a high position corresponding to the new transportation vehicle M.

Third Embodiment In the third embodiment, the guide width is common to both systems, and only the rail height position is changed when the track is modified.
Similar to the second embodiment, the outer guide rail 5 is attached to the lower two sets of plate anchor bolts 20 and 21 of the side wall 2 via the rail support 8 and the support plate 13 as in the second embodiment, and the track is modified. At some times, the inner guide rail 4 is raised by adding the support pedestal 12, and the outer guide rail 5 is transferred to the upper two sets of plate anchor bolts 21 and 22 together with the support plate 13,
The height position is changed at the same axial position.

By the way, although the anchor bolts have been taken as an example of the rail attachment and the column attachment in the above-mentioned embodiment, these attachments can be appropriately changed depending on the shape, structure, etc. of the rail column or the rail support member. Further, it goes without saying that the present invention is applicable not only to the above-mentioned double track but also to a single track.

(Effects of the Invention) As described above, according to the present invention, the work of changing the height position of the guide rails accompanying the system conversion from the guideway bus system to the new transportation system is performed by raising one of the guide rails and the other. The guide rails can be relocated easily and quickly with minimum effort and labor, which can shorten the construction period of track remodeling work for system conversion and reduce the construction cost.
