Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present application relates to a method for laying rails for a single-rail carrier and a construction vehicle therefor.

[0002]

2. Description of the Related Art Conventionally, rail laying of a single rail carrier used for agriculture such as orchards has been carried out mainly by transporting a square pipe rail of a fixed length of 5 m to the site and arranging it on a rough route.
Drive the pillars and fix the rails to the pillars, and proceed sequentially. If the straight rails make it impossible to proceed due to topography, trees, etc., bend the rails on the spot to avoid obstacles. In addition, the work was carried out by giving the processing to fit the terrain. Therefore, what is brought to the laying site are fixed-length straight rails, columns, rail connecting parts, and tools, which are loaded on a trolley that has been laid on a rail that has already been laid, and towed by a drive car before the construction. It was to carry it on the rail and wait.

[0003]

In the above-mentioned laying work, although the rough route is determined in advance, bending the rail on the spot often deviates from the determined route, It was also seen that unplanned felling of trees occurred, that the vehicle's climbing capacity limit of 45 ° was exceeded, and there was not enough space between the rails and trees to allow the dolly to come into contact with the trees. Further, when the rail is processed depending on the situation, internal stress may change due to strain, and rust may progress due to peeling of the plating. In addition, this could lead to a shortage of materials and result in laying on soft ground. Also, in the case of temporary installation for 2-3 years for material transportation to the power transmission line construction site and for transportation of workers, if the rail bending process is performed according to the unique topography,
Reuse was almost impossible.

As for the construction vehicle, when the rail was laid, the driving vehicle was in front and the truck was towed and transported to the rail in front of the construction to stand by. The rail had to be carried from the dolly and set, and it was not easy to hold the bender for local bending, the electric hammer for strut driving, and the generator at the working position on the steep slope.

[0005]

Therefore, the main rail of the present application
4, determine the bending radius and length of the straight rail, curved rail,
The rails are processed at the factory to be prefabricated so that the order of laying the rails can be determined and reused, and the construction vehicle has a rail-mounted vehicle in the front and a drive vehicle in the rear.
Rail-carrying car 9 Arm 12 is installed at the tip of
An electric hammer 14 is hung at the tip of a 12 via a balancer 13 to improve work efficiency, reduce operator fatigue on steep slopes, improve safety, and shorten the construction period.

[0006]

[Embodiment] The embodiment of the present application will be described in detail. Among the main rails 4, there are four types of straight rails of 2 m, 3 m, 4 m and 5 m, and the curved rail is bent with a radius of 10 m.
There are 3 types: one that bends to the side, one that bends to the bottom (rack side), and one that bends to the top, with a length of 2m, 3m, 4m.
From the total of nine types, rails that match the topographic route are selected and laid.

The construction vehicle 8 has a rail-carrying vehicle 9 at the front and a drive car 10 at the rear, and the rail-carrying vehicle 9 has a main pillar 1 at the bottom.
， Brace body 6 Other joint fittings, bolts, tools and other small items, and a generator 11 at the rear, and a space for loading straight and curved rails on the upper stage.
9 A pillar is provided at the center of the tip, and an arm 12 is provided so as to be rotatably supported on the tip of the pillar and a balancer is attached to the arm 12.
Suspend the electric hammer 14 via 13, and the electric hammer
It has a structure in which 14 and the generator 11 are connected via a cord. Further, in FIG. 3, a hydraulic motor 21 is provided on a rear wheel 20 among the wheels provided on the lower carriage of the rail-carrying vehicle 9, and the hydraulic motor 21 is branched from the hydraulic device of the rear drive vehicle 10 to be connected to the wheel 20. Although it has a drive unit for driving the vehicle, it is not always necessary, along with the drive vehicle 10 when the route is continuous with steep slopes, the route has many curves, or the route is long and a lot of material is loaded. By driving the rail-carrying vehicle 9, smooth progress is possible.

The method of use of the present application is described in Japanese Patent Application Laid-Open No.
As disclosed in No. 179602 , selecting a railway laying route using a computer, calculating several types and quantities of rails at that stage, processing the rails at the factory, checking all route diagrams and checking the quantity At the site, the rails shipped above are laid in the order of the numbers attached to the rails.
First of all, lay the main rails that the construction vehicles can ride on. In this case, it is also on a flat ground, and the work can be easily done by assembling a tripod and suspending an electric hammer. Next, the construction vehicle 8 was laid on the main rail 4, and the rail loading vehicle was loaded with small items such as rails, main pillars, and pillars in the lower space, and the rail was loaded on the upper level. Lay in numerical order.

As the construction procedure, as mentioned above, the support 6 is taken out from the lower stage of the rail-carrying car 9 and mounted on the main rail loaded on the upper stage (temporarily fixed), and then the front part of the rail-carrying car 9 is mounted. And tentatively fix it to the laying rail with joint fittings. Then, place it according to the route map and the site topography, insert the main pillar 1 and the auxiliary pillar 5 into the support metal fittings of the pillar body 6, and drive it with an electric hammer hung from the arm, and then the main pillar 1 and the auxiliary pillar 5 Insert the fitting material into the head, tighten the fastening bolts of the support fitting, and tighten the other bolts to complete the fixing. By repeating the above procedure, the construction vehicle is advanced as the main rail is fixed.

The laying is performed while avoiding the unevenness of the surface of the earth, trees or cableway equipment, which could not be predicted from the contour map. Such small-scale rail shape changes can be made by the vendor brought to the site and can be adjusted by the height of the main pillar.

[0011]

Since the rails used in the method of the present invention are factory processed, there is basically no bending in the field, there is no damage to the rack on the back of the rails, and residual stress due to bending can be removed by heat treatment. There is no peeling of the rail, and above all, the prefabrication makes it possible to reuse the rail because the rail bending rate is constant. For construction vehicles,
A rail-mounted vehicle is arranged in the front part, an arm is protrudingly provided at the tip,
Since an electric hammer is hung from it via a balancer, the work of driving the main pillar 1 and the auxiliary pillar 5 on a steep slope can be performed easily. In addition, the rail-carrying vehicle has two tiers. The lower tier has a main pillar 1, the auxiliary stanchion 5, the stanchion body 6 and a small space for joint fittings, bolts and tools, and the upper tier has a main rail carrying space. The pillar body 6 that has been taken out can be temporarily fixed to the main rail 4 in the main rail loading space, which is effective in improving work efficiency in places where the footing is poor.
Further, by driving the wheels of the rail-carrying vehicle 9, it is possible to proceed smoothly when the route has a continuous steep slope, a route with many curves, or a long route and a large amount of material is loaded. In addition, from the above, the moving distance of the rail should be as short as possible, and a heavy electric hammer or bender should be hung on the arm via a balancer to reduce worker fatigue, improve safety and efficiency, and improve the construction period. Can be shortened.
