つては無駄な出費ともなる欠点を有している。3-2 Prior Art A rail is supported by an arm shaft connected to a ground element for signal safety equipment (hereinafter simply referred to as a ground element) set above the railroad ties with inner and outer butts and a collar interposed between them. Conventionally, as shown in FIG. 3, for example, a nut 6 is fastened through washers 4 and 5 above a mounting shaft 3 inserted through a base plate 2 that abuts on a ground element 1. The lower threaded part 7 is passed through and screwed into one side (the right side in the drawing) of the arm shaft 8, and the inner stopper 10 is screwed into the threaded part 9 carved in the arm shaft 8, while the outer stopper 11 The collars 12 interposed between the inner butt 10 and the outer butt 11 are each fitted onto the arm shaft 8, and a tightening nut is attached to the other end (the left end in the drawing) of the arm shaft 8 via a spring washer 13. 14,
15 is tightened to hold the ground element 1 at a fixed position on the rail 16. However, in such a configuration, after the tightening nuts 14, 15 are fastened to the arm shaft 8, the tightening nuts 14, 15 may become loose due to long-term use of the arm shaft 8.
Both the screw part 9 and the threaded part 9 carved into the arm shaft 8 are rusted, and it is impossible to hold the arm shaft 8 in a fixed position when loosening the tightening nuts 14 and 15 with a tool such as a wrench. If the situation becomes extremely difficult or virtually impossible, especially if loosening is impossible, it will be impossible to replace the rail due to wear etc. or reuse the mounting bracket for the ground element, and all these parts will have to be disposed of. This method is extremely uneconomical in terms of materials, and has the disadvantage of being a wasteful expense for the user.

る。3-4 Embodiment To describe an embodiment of this invention with reference to FIGS. 1 and 2, the lower surface of the ground member 21 set on sleepers (not shown) is placed on a base plate 22, and this base plate 2
Tighten the upper part of the mounting shaft 23 that can pass through the base plate 22 with a nut 24 via the disc spring washer a and the flat washer b, and insert the split pin P near the upper end to integrally assemble the ground element 21 to the base plate 22. At the same time, the lower screw member s is penetrated and screwed into the proper position near one end (the right end in this case) of the arm axis R, so that it can be adjusted to a desired position along the vertical direction,
In addition, an inner stopper 25 with a hook is screwed onto a threaded part d carved in the arm shaft R, and the threaded part d is passed through a through hole e of an outer stopper 26 with a hook. A collar 27 interposed between the outer butts 25 and 26 is fitted into the threaded part d, and the middle of the lower surface of the rail 28 is placed and supported by the collar 27. ), tightening nuts J and K are fastened to the arm shaft R via spring washers W to suppress deflection of the rail 28 due to passing trains. However, the mounting shaft 2 on the ground element 21 side
3 and the inner abutment 25, the gripped part N, for example, a nut or a detent, is fixed in a bulged state by welding or the like at a suitable position of the arm axis R near the inner abutment 25, so that it is integrated with the arm axis R. It is combined with In the figure, F is a grooved nut, q is a cotter pin, and 29 is a bottle.

ものである。3-5 Actions and Effects In this invention, the arm axis R and this threaded part d
The tightening nuts J and K that are screwed into the
When the nuts J and K become rusted due to exposure to wind, rain, dust, etc. and become integrated, and the tightening nuts J and K cannot be loosened with a tool such as a wrench (not shown), the gripped part N, for example, the nut. is held with a suitable tool or other material, and the arm shaft R is temporarily firmly fixed in a certain position, and the tightening nuts J,
When holding a tool such as a spanner in K and rotating it, the arm shaft R is fixed, so the tightening nuts J and K can be easily rotated and loosened, and the tightening nuts can be tightened as necessary. By separating the J and K spring washers W from the arm shaft R, the inner and outer butts 25 and 26 and the collar 2 are removed.
7 can be removed from the arm shaft R. Therefore, rail 2
8 needs to be replaced due to wear, etc., or when changing the mounting position of the ground element 21, the mounting bracket itself can be used, but the tightening nut on the outer side of the arm may become rusted and loosened. Compared to conventional mounting brackets, which necessitate the disposal of all parts and wasteful expense for the user,
This invention is extremely economical for the user as only the parts that cannot withstand use can be replaced, and it is extremely economical for the user to fix the gripped part, such as a nut or detent, to the arm shaft. The tightening nut on the outer abutment side can be easily loosened by a simple means, making it easy for anyone to handle, and furthermore, fixing the gripped part to the arm shaft will cause problems with the structure and function of the arm shaft. It has such practical benefits that there is no risk of it happening.

合・回動するようにしてもよい。 Although the above is an explanation of an embodiment of an arm shaft assembled to a ground element, the present invention is not limited to this, and can also be applied to loosening nuts in rail spacing rods, connecting rods, etc. in point equipment, for example. In addition, instead of a nut or a rotation stopper as the gripped part N, a square or hexagonal corner part is set on a part of the arm shaft R, and a tool such as a spanner is attached to this corner part. It may also be configured to engage and rotate.
