Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rail fastening device for a narrow crane garter.

[0002]

[Prior art]

 In a conventional rail fastening device for a narrow crane garter, as shown in FIG. 9, bolt insertion holes b are provided on both sides of a crane garter a, and a holding bolt d is provided on the fastening device c as described above. Direct bolt type in which bolts are inserted through holes b for fastening, or as shown in FIG. 10, floor plates e are welded to both ends of the crane garter a, and fastening is performed across the floor plates e and the crane garter a. There is a welding type in which the device c is fixed by welding.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned direct bolt type, the expansion of the bolt insertion hole b cannot be performed because it leads to a decrease in the strength of the crane garter a, and the strength and fastening force corresponding to the improvement in the speed and operating rate of the overhead crane cannot be obtained. The current situation. In addition, there are problems such as a bolt falling accident due to loosening of bolts, and rail meandering.

Further, in the above-mentioned welding method, since the laying plate e is required, there is a problem that the cost becomes high and it takes a lot of time and labor. Therefore, in order to solve the above-mentioned problems, the present invention aims to provide a fastening device that can be attached to a narrow crane garter without requiring bolt holes and floor plates.

[0005]

[Means for Solving the Problems]

 The gist of the present invention is that a clip fitting groove is engraved along the side surface on the rail side, and a cradle in which a clip locking bolt is threadedly penetrated approximately at the center of the clip fitting groove, and a base end side thereof. A clip locking portion that can be fitted into the clip fitting groove portion is formed in a protruding manner, and the pedestal is welded and fixed to both sides of the flange, and the tip of the clip has a U-shape in the vertical direction. This is a rail fastening device for a narrow crane garter characterized in that a plurality of formed rail pressing bolts are threadedly penetrated, and both ends of the rail base are pressed and fixed by the tips thereof.

[0006]

[Action]

 In the fastening device of the present invention, as shown in FIGS. 7 and 8, the pedestals 1 and 1 are fixed by welding D to both sides of the rail 10 mounted on the narrow crane garter 9. Then, the clip locking portions 6 and 6 of the clips 5 and 5 are slidably fitted into the clip fitting groove portions 2 and 2 of the receiving bases 1 and 1 and fixed to the receiving base 1 by the clip locking bolts 4.

Next, both ends of the rail 10 are fastened and fixed by the tip of the rail pressing bolt 8 which is screwed through the rail pressing bolt hole 7 of the clip 5. In this case, by forming the tip of the rail pressing bolt 8 in a U-shape, it is possible to sufficiently cope with the inclined surface at any position of the rail 10, and the rail 10 can be firmly fixed on the crane garter 9. Can also be fixed to.

[0008]

【Example】

 Hereinafter, a fastening device according to the present invention will be described in detail with reference to the drawings showing an embodiment thereof. FIG. 1 is a plan view of the pedestal of the present invention, FIG. 2 is a front view of the same, and FIG. 3 is a side view of the same.

The pedestal 1 has a substantially rectangular shape with a leg length A of 130 mm, a depth B of 20 mm, and a height C of 42 mm, and a clip fitting groove 2 is formed along the back side of the pedestal 1. Of. A clip locking bolt hole 3 is provided substantially at the center of the clip fitting groove portion 2 so that a clip locking bolt 4 shown by an imaginary line in FIG. 3 is screwed.

Next, FIG. 4 is a plan view of the clip of the present invention, FIG. 5 is a front view of the same, and FIG. 6 is a side view of the same. The clip 5 has a clip engaging portion 6 protrudingly formed along the base end side thereof so as to be fitted into the clip fitting groove portion 2 of the pedestal 1. Further, rail holding bolt holes 7 and 7 are provided on both sides of the plane of the clip 5, and a rail holding bolt 8 is screwed through the rail holding bolt hole 7 as shown by an imaginary line in FIG. And The tip of the rail holding bolt 8 is formed in a U shape so that it can cope with the inclined surface at the rail mounting position.

[0011]

[Effect of device]

 According to the present invention, the existing narrow crane garter can be attached to the pedestal without newly adding bolt holes or without the need for a floor plate, and the clip can be attached to and detached from the pedestal. By doing so easily, it is possible to replace the rail easily and in a short period of time. Further, by forming the tip of the rail pressing bolt in a U-shape, it becomes possible to deal with the mounting position of the rail in an almighty manner.
