Description of the Related Art A main rail is laid at a central high place, two sub-rails are laid at a low place on the right and left, and a rack or the like is stuck on the main rail, and a driving function of a towing vehicle is engaged with the main rail. In addition, there is a simple rail-type vehicle that travels with a sub-rail having the weight and guidance function of the vehicle. Such a rail type vehicle can be used for transporting materials and personnel in an orchard, a construction site, and the like because it can climb up a slope even on a considerably sloped place.

[0003]

However, it is not easy to lay the rails because they are provided with three convenient rails and at different heights. In other words, each rail must always be laid at the same interval and undulation. To lay this, all rails must be laid at the same time with high accuracy, or the remaining rails will be Must be laid with high accuracy. However, since the number of rails is large and the heights of the rails are different, either method is troublesome. The present invention has been made to solve the above problem, and is capable of automatically laying one rail once the rail is laid.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the present invention is a rail base for mounting a main rail at a high center and sub rails at low right and left places according to the present invention. However, a rail base is provided on a base body laid on the ground or at a fixed height above the ground, in which a pocket on which each rail can be mounted is provided, and the rail is attached to the pocket. It is.

According to the present invention, by laying the base body with reference to one rail, the remaining rails need only be attached to pockets provided in the base body. That is, each rail may have a gradient in the direction of the line, but usually must be horizontal in the direction of the line width (left-right direction). Therefore, if each rail base is laid while raising the level in the left-right direction with reference to the reference rail, the remaining rails may be simply attached to the pockets. For this reason, the entire rail can be laid easily and quickly, and each rail is placed on the base body, so that stability and fixability are improved.

It is characterized by laying the base body, and then attaching the remaining rails to each pocket. In this case, there is a mode in which the base body is laid continuously or at intervals, according to claim 8.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing a state in which rails are laid by a rail base according to the present invention, FIG. 2 is a side view,
FIG. 3 is a cross-sectional view. This rail base comprises a base body 1 formed in a square shape with three vertical members 1a and two horizontal members 1b fixed to the front and rear ends of the vertical members 1a. It is the subject. Note that the vertical member 1a and the horizontal member 1b in this example both use square pipes.

A main rail 2 is mounted at a high place at the center of the upper surface of the base body 1, and two sub-rails 3 are mounted at low places on the left and right of the main rail 2.
Can be attached to pockets 4 and 5 provided on the upper surface of the base body 1. Of these, the pocket 4 for the main rail 2 includes a central vertical member 1a and a horizontal member 1a.
The main rail 2 is attached to a column 6 inserted into a pocket 4 formed by the cylindrical body 4a.

The two front and rear pockets 4 are provided on one base body 1 so as to protrude from the main rail 2. The column 6 is a pipe having an upper end to which a mounting plate 7 is fixed. The lower end is inserted into the pocket 4 and fixed with screws 8 or the like. The main rail 2 of this embodiment is a rail with a rack, which is formed of the same square pipe as the vertical member 1a, is fixed to the side surface of the mounting plate 7 with screws 9 and the like, and has a rack 10 attached to the lower surface.

The pocket 5 for the sub rail 3 is
The upper and lower ends of the left and right sides of b have two plates 5a and 5b whose upper ends protrude therefrom, and the sub rail 3 is fitted between the plates 5a and 5b (pocket 5). In this case, the sub-rail 3 does not exert much force in the lateral direction due to the weight of the vehicle traveling thereon,
No particular fixing structure is taken for the pocket 5 (of course, it may be fixed with a bolt or the like). The two front and rear pockets 5 are provided on one base body 1 for the same reason as described above, and the sub rail 3 is also formed of the same square pipe as above.

As described above, the main rail 2 is connected to the base 1
And the sub-rails 3 are provided at both ends of the base body 1. Therefore, the respective pockets 4 and 5 are attached to the base body 1 so as to have this arrangement. Since the main rail 2 is applied to the side of the mounting plate 7 attached to the support 6, the support 6
Is shifted from the center by that amount.

The base body 1 is sometimes placed on the ground, but in most cases it is supported on the ground by supporting legs 11. For this reason, a support leg attachment portion 12 for attaching the support leg 11 to the base body 1 is attached. FIG. 5 is a side view of the support leg attachment portion (hereinafter, attachment portion) 12. The plate body 12 a is fixed to the outer surface of the vertical member 1 a of the base body 1 with bolts 13, and attached to one end of the plate body 12 a. The pipe-shaped support leg 11 is formed of a cylindrical body 12b.
And fix it with bolts 14. In this case, the plate body 12a can be tilted with respect to the base body 1 at a portion such as a bolt 13 so that the support legs 11 are vertical even if the base body 1 is tilted back and forth. By laying on the ground in this way, it is not necessary to level the ground, so that the laying cost can be reduced.

The support leg 11 is buried under the ground at a depth sufficient to provide a necessary support force. At this time, the support leg 11 is passed through a subsidence prevention plate 15 and the subsidence prevention plate 15 is mounted on the ground. In this position, the support leg 11 is fixed to the support leg 11 with a bolt 16 or the like. Four mounting portions 12 to which such support legs 11 are mounted are provided on the base body 1, and the length of each support leg 11 is adjusted to obtain the level of the base body 1 in the left-right direction.

Next, a method of laying the rails by the base body 1 will be described.
And the main rail 2 is mounted on the mounting plate 7 at a set gradient. In this case, the length of the main rail 2 may be arbitrary, but is generally set to be equal to or longer than the length of the base body 1. In this state, the support body 11 of the base body 1 is adjusted so that it is horizontal in the left-right direction. As described above, since the main rails 2 and the sub rails 3 are basically horizontal in the left-right direction even if there is a gradient in the line direction, the base body 1 is horizontal in the left-right direction. However, since the inside sub-rail 3 is set lower by a predetermined amount at the time of a curve, the base body 1 is also adapted to this.

Next, the main rail 2 is connected with a predetermined height and gradient. FIG. 4 is a cross-sectional view showing this extension structure. A metal fitting called a core 17 is attached to both main rails 2.
And insert them into each of them (at this time, also adjust the phase of the rack 10), and make each main rail 2 and core 17
Are connected through bolts 18 and the like. In this way, the work of elevating the base body 1 to which it is attached on the basis of the main rail 2 and installing it on the ground is performed along the route, and when this is completed, the sub rail 3 is inserted into another pocket 5 of the base body 1. Attach.

At this time, since the pockets 5 are provided at predetermined positions of the base body 1 and each base body 1 is installed with high accuracy, it is not necessary to take out the level of the sub-rail 3 and simply fit it. Just go there. The sub-rail 3 must also be connected appropriately. In this case, a joint 19 having a U-shaped cross section, which is open across the two sub-rails 3, is applied from the vertical member 1a to the sub-rail 3, and a bolt 20 or the like is passed therethrough. If connected, the vertical member 1a
Can be continued wherever exists. Although the above description is based on the main rail 2 for installing the base body, any one of the sub rails 3 may be used as a reference.

The above base members 1 may be provided continuously or may be provided at intervals. According to the latter, there is an advantage that the number of the base bodies 1 can be reduced, but the sub-rails 3 where there is no base body (and the main rails 2 in some cases) may be provided with supporting legs 21 similar to those described above for supporting the sub-rails 3. is there.

FIG. 6 is a side view of the case where each of the rails 2 and 3 is laid at an inclination in the direction of the road. In this case, both the main rail 2 and the sub-rail 3 are bent up and down by a predetermined radius. Use the base body 1
Will be laid with an inclination corresponding to this curvature.
At this time, the support legs 11 need to be vertical, but it is sufficient that the plate body 12a constituting the mounting portion 12 is inclined with respect to the base body 1 as described above.

FIG. 7 is a side view of a carrier running on the rails 2 and 3, and FIG. 8 is a cross-sectional view. The carrier is a towing vehicle 22 and materials and the like towed by the towing vehicle 22. And a carriage 23 on which personnel are placed. Towing vehicle 2 in this example
Reference numeral 2 denotes a main rail 2 for obtaining a driving force and a steering force, and a sub rail 3 for obtaining a weight supporting force. The driving force is controlled by the rack 10 attached to the lower surface of the main rail 2.
Is provided by driving the engine 25. The drive wheels 24 are provided with flanges having flanges 24a along both sides of the main rail 2 to prevent derailment.

On the other hand, the steering force is the main rail 2
For preventing derailment along both sides by rolling on the upper surface of
A flanged rolling wheel 26 having 6a is provided, and the main rail 2 is sandwiched between the rolling wheel 26 and the driving wheel 24 from above and below. With this configuration, the main rail 2 bears the weight of the towing vehicle 14 to some extent.

On the other hand, the main weight supporting force is that two rollers 28 mounted on the sub-rail 3 are attached between the both side plates 27, and the two rollers 28 are rotated around the pins 30 with respect to the attachment 29 in a vertical plane. The enabled roller set 31 is attached to the vehicle body. In this case, the width of the roller 28 is considerably larger than the width of the sub rail 3 to prevent derailment. still,
Although not shown, some towing vehicles 22 do not act on the sub rail 3. In this case, only the driving wheel 24 and the rolling wheel 26 mounted on the main rail 2 can obtain the steering force and the weight supporting force.

On the other hand, the roller set 31 is also
Is mounted on the sub-rail 3 so as to travel on the sub-rail 3 with both the steering force and the weight supporting force (not mounted on the main rail 2). In addition, the towing vehicle 22 and the bogie 23 are connected by a towing rod 32 having a universal joint mechanism.

FIG. 9 is a front view of a base body 1 showing another embodiment of the present invention.
Two left and right second sub rails 33 outside the pocket 5
Is provided with a pocket 34 to which a. The pocket 34 is also composed of two plate bodies 34a and 34b, between which the second sub-rail 33 is fitted. Note that the extension structure of the second sub rail 33 may be the same as described above. Thus, the greater the number of rails, the higher the usefulness of the rail base. However, the number of subrails may be more than this.

FIG. 10 is a rear view of the carrier in this example, in which two vehicles 35 running on a narrow gauge (sub rail 3) and two vehicles 36 running on a wide gauge (second sub rail 33) are provided (towing vehicle). Should run on the main rail 2). Thus, if the vehicle 35 running on a narrow gauge is loaded with materials 37, the vehicle 36 running on a wide gauge is equipped with cargo handling equipment 38, and the vehicle 35 running on a narrow gauge can enter the vehicle 36 running on a wide gauge. Transport and unloading work becomes possible.

[0028]

As described above, according to the present invention, by laying the base body with reference to one rail, the remaining rails need only be attached to the pockets provided in the base body. That is, each rail may have a gradient in the direction of the route, but must be horizontal in principle in the direction of the width of the route (left-right direction). Therefore, by laying each rail base while raising the level in the left-right direction with reference to the reference rail, the remaining rails can be simply attached to the pockets. For this reason, the entire rail can be laid easily and quickly, and each rail is placed on the base body, so that stability and fixability are improved.
