[0002]
[Prior art]
Conventionally, in order to transport the long materials as described above from the material storage place to the destination place through the forest or the like, it has been mostly performed by a heavy machine having a crawler. As such a long material, for example, there is a pipe of a pipeline, but the pipeline often passes through the equatorial rainforest area, and for that purpose, the equatorial rainforest must be cut down over a width of 10 m, The environment was destroyed. In addition, such lands include slopes, particularly steep slopes near 45 °, and it was impossible to climb by heavy machinery. Therefore, a wider logging width was required to climb the meandering slope, which caused further deforestation.
[0003]
[Problems to be solved by the invention]
Therefore, the applicant of the present invention has proposed a transporting device that can be used only for a narrow logging width (about 3 m) and can also climb an inclined land of about 45 ° (Japanese Patent Application No. 2001-13301), and has obtained a corresponding evaluation. However, this proposal has a problem that the installation width increases and the installation cost increases because two sets of rails, which are one set of left and right, are required in principle. Therefore, the present invention enables this by only laying two rails on the left and right.
[0004]
[Means for Solving the Problems]
Under the above-mentioned problems, the present invention is a long material transporting device for transporting a long material placed in a material storage area to a destination location according to claim 1, and the transporting device includes the material storage location and the destination location.

According to this, the rail 1 is laid at a certain height above the ground, and the ground leveling can be rough, and there is an advantage that laying on an inclined land or the like is easy. And in this example, the rack 8 is stuck on the lower surface (an upper surface or a side surface) of the rail 1.
[0010]
The transporting vehicle 3 is capable of carrying the material 2 and traveling across the left and right rails 1, but is positioned at the front end and the rear end of the material 2 in the present invention. Each transport vehicle 3 includes a load facility 10 that lifts and lowers the material 2 on a frame 9 and a load facility 11 that holds the material 2 suspended by the load facility 10 at a predetermined height. Have. Among these, the suspended load equipment 10 has a hoist 13 or the like attached to the center of the gate 12 assembled on the underframe 9.
[0011]
The load-carrying equipment 11 is a structure in which a contact plate 16 that is applied to the upper surface of the material 2 and is integrally bound by a wire 15 or the like is suspended from a gate 14 assembled on the underframe 9. FIG. 9 is a partial cross-sectional front view of the abutment plate 16. The abutment plate 16 is suspended from a mounting member 17 fixed to the center of the gate 14 by a suspension member 18. The material 18 can rotate horizontally with respect to the mounting material 17, and the abutment plate 16 is pivotally attached to the suspension member 18 by a pin 19 so that it can be bent back and forth. In some cases, the rail 1 is laid on a slope or a curve. Even in such a case, the load carrying facility 11 can carry the material 2.
[0012]
The above-described suspended load facility 10 and the load bearing facility 11 are provided side by side on the underframe 9, but in the transport vehicle 3 that transports the front end of the material 2, the load bearing facility 11 is at the rear, In the transport vehicle 3 that transports the rear end, the load-carrying facility 11 is present in the front. In addition, although the above hanging load equipment 10 and the load carrying equipment 11 are both fixedly provided in the center of the gates 12 and 14, they may be movable in the left-right direction (of course, the fixing mechanism is Necessary) This makes it easier to deal with the case where the left and right positions of these materials 2 are different.
[0013]
A wheel unit 20 is attached to the transport vehicle 3, and the wheel unit 20 travels on the rail 1. The wheel unit 20 of this example is attached to the underframe 9, two in front and behind on one rail 1, for a total of four. 5 is a side view of the wheel unit 20, FIG. 6 is a cross-sectional view taken along the line CC of FIG. 5, and FIGS. 7 and 8 are cross-sectional views of the wheel unit 20. A flange type lower ring 21 and an upper ring 22 for sandwiching 1 from above and below are provided on the mounting plate 23. Therefore, the lower wheel 21 and the upper wheel 22 do not come off the rail 1 and are not removed, but on the other hand, when the width and height of the two rails 1 are different (actual problem, full length It is impossible to combine them over a long period of time), and in some cases, running may become impossible.
[0014]
Therefore, a left and right moving mechanism 24 that can move left and right is provided for the wheel unit 20 on the one rail 1 side. That is, the mounting pin 25 is protruded from the mounting plate 23 in the left-right direction, and the mounting pin 25 is inserted into and supported by the frame-side sleeve 26 provided in the frame 9 so as to be slidable in the left-right direction. Thereby, if the widths of the left and right rails 1 are different, the mounting pin 25 provided on the wheel unit 20 moves to the left and right with respect to the frame side sleeve 26 to cope with it.
[0015]
Similarly, a vertical movement mechanism 27 is also provided for one of the four wheel units 20. That is, the upper and lower pins 28 are integrated with the mounting pin 25 described above, and the upper and lower pins 28 are inserted into and supported by the frame side sleeve 29 provided on the frame 9 so as to be slidable in the vertical direction. Thus, if the left and right rails 1 are different in the vertical direction (level), the vertical pin 28 moves up and down with respect to the frame side sleeve 29 to cope with it. The remaining three wheel units 20 are grounded on the principle of three-point grounding even if the rail 1 is different between the upper and lower sides and the right and left sides. .
[0016]
In addition, the transport vehicle 3 is also provided with a brake device 30. In the brake device 30 of this example, a hanger 31 is suspended from a base frame 9, and another rack 32 that engages with the rack 8 of the rail 1 is attached to the lower end of the hanger 31 with a bolt 45. Then, the insertion hole of the bolt 33 for attaching the hanger 31 to the underframe 9 is moved to the left and right so that the hanger 31 can be moved left and right, etc. When releasing the brake, the hanger 31 is moved to engage the rack 32 and the rack 8. When the brake is operated, the hanger 31 is moved in another direction to engage the rack 32 and the rack 8.
[0017]
This is because when the material 2 is unloaded, the brake device 30 needs to be operated and firmly fixed. In order to match the phases of the racks 8, 32, the rack 32 of the brake device 30 can be moved slightly back and forth by another bolt / long hole mechanism 35. Furthermore, the mounting holes 46 of the bolts 45 formed in the hanger 31 are elongated vertically so that the rack 32 can be moved up and down to some extent even with respect to vertical distortion of the rail 1.
[0018]
The transport vehicle 3 is pulled by the towing vehicle 4. The towing vehicle 4 of the present example is a single rail type that travels on the left and right rails 1 with the engine as a driving force, and an engine-driven power generation is provided at the front portion of the base frame 9 of the transport vehicle 3 in front. The machine 36 is mounted and the electricity generated by this is supplied to the hoist 13 and the like of the suspended load equipment 10. Although not shown, the towing vehicle 4 is equipped with a transmission device having a clutch and a speed reduction mechanism in addition to the engine, and finally drives a pinion that meshes with the rack 8 to move forward or backward. In addition, the transmission device incorporates a brake mechanism that applies a brake by tightening an appropriate transmission shaft or the like so that it can be stopped at an arbitrary position. Further, the transport vehicle 3 may be equipped with a pinion that meshes with the rack 8, and a brake mechanism that applies a braking force to the pinion may be attached.
[0019]
In addition, a seat base 37 on which a driver sits is provided at the front portion of the transport vehicle 3 in front. The tow vehicle 4 and the transport vehicle 3 (seat base 37) are connected by a tow bar 38. In this case, since the transport vehicle 3 extends over the two rails 1 and the towing vehicle 4 is mounted on each rail 1, the tow bar 38 that connects the towing vehicle 4 and the transporting vehicle 3 is also provided. , Two of the own side 38a and the other side 38b are provided. This is because the speed of the towing vehicle 4 (especially the speed of acceleration immediately after start-up) is slightly different between the left and right, so that it can be leveled.
[0020]
Next, description will be made by taking as an example a case in which the pipe 2 of the pipeline having a long route length as the material 2 and including a considerable slope is sequentially laid by the above conveying device. First, as described above, the rail 1 is laid along the pipeline starting from the material storage. In this case, the pipe 2 is formed by digging and filling a groove (hole) 39 on the ground, and the rail 1 is laid on both sides of the groove 39. Next, when the pipe 2 is loaded on the two front and rear transport vehicles 3 using the hoist 13 of the suspended load facility 10, the pipe 2 is applied to the abutment plate 16 of the load bearing facility 11 and tied with the wire 15. The wire 40 is stretched and fastened by the chain block 41 to be fixed.
[0021]
In this case, the place to be transported first is the place farthest from the material yard in the planned laying area, and accordingly, the towing vehicle 4 is in the reverse state located at the end in the traveling direction. Once transported to the destination, the load carrying facility 11 is released, the pipe 2 is lowered using the suspended load facility 10, the front and rear transport vehicles 3 are connected by connecting rods (not shown), and are pulled by the towing vehicle 4. Return to the material place in an empty state (Kotoki is in a forward state where the towing vehicle 4 is located at the head). Such a transportation form is repeated one after another and laid throughout the planned laying area. However, the method of transporting sequentially from a location close to the material storage location to a location far from the location, and also towing and transporting the tow vehicle 4 at the head (in this case, the transporting device takes a form of proceeding beyond the material 2) is naturally taken. Conceivable.
[0022]
FIG. 10 is an explanatory diagram showing this state. Normally, when the pipe 2 of the pipeline is transported to the destination, it is integrated with the pipe 2 already transported by welding or the like. Therefore, the end of the pipe 2 on the side closest to the material storage is lifted using an appropriate support base 42 (becomes inclined), and the two support bases 42 are adjusted for the pipe 2 that has been transported. Then, the pipe 2 is adjusted to be a straight line. In this state, they are welded and integrated, and when this is completed, the rear support base 42 is removed leaving only the support base 42 at the extreme end. Efficient laying can be performed by repeating such operations one after another.
[0023]
【The invention's effect】
As described above, the present invention is as described above, and it is only necessary to run a transport vehicle that lays a rail from a material storage area to a destination location and pulls it on a tow truck. It is sufficient that only the width of can be secured. Therefore, the width of felling and leveling can be minimized, the cost can be reduced, and environmental destruction can be suppressed even when cutting a forest or the like. Then, long materials are loaded on the long material transport device at the material yard, traveled to the destination location and unloaded, and the operation of returning to the material yard with empty load is repeated, thereby efficiently transporting long materials ( Laying).
