However, in the illustrated example, a side plate 7 is also suspended from the rear side edge of the top plate 2. The side plate 7 is used for scoring and is formed so as to correspond to the distance from the top surface of the rail 31 to the punch position.

  On the upper surface plate 2, a means for firmly fixing the main body case 1 to the rail 31 during operation, and a vertical scale of a curved ruler (right angle ruler) 10 for the measurement, as will be described later, In addition, a means for firmly supporting the music scale 10 is installed.

  Usually, as a fixing means to the rail 31, a magnet 8 with a changeover switch is used. The magnet 8 with a change-over switch changes the magnetic force by switching the switch 9, and when the switch is turned on, the magnet 8 is firmly magnetized by a strong magnetic force acting on the top surface of the rail 31 via the top plate 2. When the switch is turned off, the magnetic force disappears and the auxiliary device can be detached from the rail 31.

  Moreover, as a support means of the curved scale 10, a pair of magnet holders 11 and 12 are usually used. The magnet holders 11 and 12 are juxtaposed so that the respective magnetized surfaces are parallel to the measuring scale 4 and support the horizontal portion of the curved scale 10 on the magnetized surface during the rail punching operation. . At that time, a stopper 13 is provided on the upper surface plate 2 in order to easily and surely align the right end of the curved scale 10 with the position of the zero point of the measuring scales 4 and 5. In the illustrated example, a fixing member for installing the magnet 8 with a changeover switch on the upper surface plate 2 serves as the stopper 13.

The magnet holders 11 and 12 are magnetically attached at the positions where the side end portions come into contact with the stopper 13.

  Then, after the water string 34 is stretched between the reference piles, the main body case 1 is placed at an approximate position on the rail 31 near the rail punch placement portion with the switch 8 of the magnet 8 with the changeover switch turned off. The main body case 1 is shifted and moved until the vertical scale of the curved scale 10 hits the water thread 34. When the vertical scale hits the water thread 34, the magnet 8 with a changeover switch is turned on. Thus, the auxiliary device can be firmly fixed at a predetermined position on the rail 31 without being manually pressed by the operator, and thereafter, the operator can work using both hands freely.

  At that position, the rail head side exposed in the punch hole 19 is a rail punch placement point. The position corresponds to a predetermined rail punch placement point as described above. Therefore, the operator operates the commercially available punching punch 32 with both hands, hits the punch against the punch hole 19 and performs the punching operation. Thus, the punch mark can always be engraved at a predetermined position without requiring any measurement.

  In addition, in order to perform the advance measurement using the rail punch placing auxiliary device having the above-described configuration, first, the water string 34 is stretched between predetermined reference piles, and then the placing straight scale 6 is set. The main body case 1 with the change-over switch 8 and the switch 8 switched off is placed at an approximate position on the rail 31 in the vicinity of the rail punch placement portion, and is looked into from the confirmation window 17 to mark the punch mark 33. Watch closely. In the case of the above-mentioned placing work, the main body case 1 is shifted and moved until the punch mark 33 coincides with the 0 point position of the measuring scales 4 and 5, and then the magnet 8 with changeover switch is turned on. Secure the auxiliary device firmly in the same way as above.

  When the auxiliary device is fixed in this way, when the water line 34 is on the right side of the punch mark 33 when viewed from the outside of the gauge (see FIG. 5), the curved scale 10 is shown in FIG. In the sliding groove 14, it is slid in the sliding groove 14 until the vertical scale hits the water thread 34. Then, when the vertical scale hits the water thread 34, the scales of the measurement measuring scales 4 and 5 indicated by the right angle portion (0 point of the horizontal scale) of the curved scale 10 are read. Needless to say, this value is the amount of advancement. When the water line 34 is on the left side of the punch mark 33, the curved scale 10 is turned upside down and placed in the sliding groove 14, and the amount of advance is read in the same manner as described above.

  As described above, the auxiliary device according to the present invention has a great feature that it can be used for both a rail punching operation and a travel amount measurement operation. It is very useful to simplify and allow non-experts to perform these tasks quickly, accurately and safely.
