Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The rail connecting structure of a single rail carrier according to the present invention prevents abnormal deformation of a hole or a rack provided in the rail at a rail joint where the drive wheels of the single rail carrier mesh. Therefore, the present invention relates to a connecting member that pulls and fastens a pillar of a rail support member or a rail support fitting.

[0002]

2. Description of the Related Art The rails of a single rail carrier that travels on a steep terrain have a square steel pipe with continuous holes or a rack-shaped iron material welded into the square steel pipe. Connected with the rail joint, fastened with bolts and extended, fastened the rail with the rail support metal fittings provided on the side of the rail, and fixed the rail support metal fitting to the tip of the pillar of the rail support member established from the ground. Things are common. In recent years, heavy goods are being transported by a single rail carrier, but the problem at this time is the durability of rails with holes or rails with racks and rails with holes or racks. . A single-rail transporter obtains thrust from a drive wheel that meshes with a hole or rack, but when a heavy object is transported, a considerable amount of reaction force is applied to the hole or rack, and the rail joints are for bolts that have been fastened. There is a drawback that the rail joint is opened by the amount of the backlash.

Further, since it is necessary to efficiently install the rails of the single rail carrier on the sloping ground, it is required to easily install the rails on the sloping ground, and the square steel pipe used for the rail uses a thin wall material for weight reduction. . For this reason, if the transportation is repeated for a long period of time, the holes formed in the rails of the joint will be widened by the fastening bolts due to the driving reaction force of the single-rail carrier, and the rails of the rail joint will gradually become wider and wider. The rack pitch shifts. As a result, the holes and racks have a wider pitch, resulting in non-uniform meshing of the drive wheels and abnormal deformation of the holes and racks provided on the rails of the joints, causing the drive wheels to bite the rails and make it impossible to run. was there. For this reason, holes and racks other than rail joints have little wear and deformation and can be used continuously, but the deformation of rail joint holes and racks is large. You have to replace the rails. Due to the material cost and the construction cost for this, the cost of the single-rail carrier was increased.

There is a method of welding the rail after the rail is installed in order to prevent the rail seam from opening, but when the single rail carrier is used as a transportation means for civil engineering, the civil engineering is completed. After that, it is necessary to remove the rail, and in that case, it is necessary to delete the welding of the rail joint of the rail installed on the sloping ground, which is a great increase in man-hours and is not practical.

[0013]

[First Embodiment] A rail 1 using a square steel pipe, in which a lower surface of the rail 1 is continuously formed with a hole for engaging with a projection of a drive wheel. Although this hole is not shown, it is used in a conventional rail and is known. The rails are connected by a rail joint (not shown in FIG. 1, but the same kind as the joint shown by reference numeral 8 in FIG. 3 is used), and one end of the rail joint is connected to the rail support fitting 3 and the rail 1.
Are fastened together with the rail fastening bolts 11. At the other end of the rail joint, the adjacent rail 1 is fastened with a bolt 9. The rail support metal fitting 3 is fixed to the established support pillar 4 on a support base 6 supported by two sub-support pillars 7 driven into the ground. Further, on the support base 6, on the left and right sides of the rail 1, support metal fittings 10 for supporting the auxiliary rail 2 for preventing the body from rolling over are provided. Since the connecting member 5 is provided between the columns 4 and is fastened so that the joints of the rails do not open, the structure is such that rattling does not easily occur between the rails. In the first embodiment, a turnbuckle is used as the connecting member 5 to facilitate adjustment with the column spacing and to secure a sufficient pulling force by the turnbuckle.

[0014]

[Embodiment 2] Rail support fitting 3 and rail fastening bolt 1
1 is used to connect the rail support metal fitting 3 and the adjacent rail support metal fitting 3 sandwiching the rail connecting portion with a turnbuckle. This has the effect of preventing looseness at the joint. The second embodiment is because the rails can be attracted to each other at a position extremely close to the rail connecting portion. Since both ends of the connecting member 5 are fastened to the rail support fittings 3 with the fastening bolts of the rail, it is not necessary to provide the auxiliary member 12 for fastening the connecting member 5. Therefore, the object of the present invention to improve the durability of the rail can be achieved efficiently at low cost.

The rail is fastened to the rail support fitting 3 attached to the upper portion with fastening bolts 11, and the other rail is fastened with bolts 9. The rails 1 between the adjacent columns are connected by joints 8 inserted in the joints of the rails, and when the drive wheels mesh with the racks 13 and the single rail transporter travels frequently, the reaction force generated in the racks opens the rails. The rack 13 is deformed, and the pitch of the rack and the pitch of the drive wheels do not match,
The engagement between the drive wheels and the rack is not enough and the vehicle cannot run.

[0016]

The effects of the present invention are achieved as follows by the configurations described in each of claims 1 to 3.

The effect of the first embodiment is that a connecting member is provided between the columns, the rail is fastened to the rail support fitting mounted on the upper part of the column with a rail fastening bolt, and the joint between the columns is connected by the connecting member. Since the parts are fastened so that they do not open, there is less play between the rails.

Since the turnbuckle is used as the connecting member, it is possible to easily adjust the space between the columns. The pulling force of the turnbuckle attached to the auxiliary member provided on the column can be sufficiently secured.

The effect of the second embodiment is that the rail support metal fittings and the fastening bolts for the rails are used to connect the rail support metal fittings and the adjacent rail support metal fittings sandwiching the rail connection parts by a turnbuckle, thereby connecting the rail connection parts. Rails can be reliably attracted to each other at a position extremely close to.

The present invention prevents abnormal deformation of a hole provided in a rail in which a drive wheel of a single-rail transporter meshes or a rack provided in a rail, keeps a hole or a rack pitch constant, and expands the hole. It is possible to improve the durability of the rail by eliminating the non-uniform meshing of the drive wheels due to the deformation of the rack.
