The conventional tamping position indicating device 3 of the tamping mechanism 2 provided in each set is located between the left and right tamping mechanisms 2 on a mounting seat 6 provided on the cross beam 5 of the frame 4 of the track straightening machine 1, and It was constructed by attaching an indicator plate 7 made of metal, rubber, etc. so as to coincide with the center of each tamping mechanism 2.
In this case, the tip of the indicator board 7 can only be lowered to the construction limit of the track, so the tip of the indicator board 7 must be 35 mm or more above the tread of the rail 8. If the rail 8 is a 50 ps rail, Instruction board 7
The gap between the tip of the rail and the top surface of the sleeper 9 is 180 mm or more, and this gap varies depending on the type of rail. Therefore,
While moving the track straightener 1 on the rail 8, when the tip of the indicator plate 7 coincides with approximately the center of the width of the sleeper 9, the track straightener 1 is stopped, and the tamping mechanism 2 is activated by the hydraulic cylinder 10. When performing roadbed compaction work by lowering the tamping tool 12 of the tamping mechanism 2 into the roadbed gravel 13 by lowering it along the guide rod 11 and pushing the roadbed gravel 13 onto the lower surface of the sleepers 9, the instruction plate 7 Since the gap between the tip of the indicator board 7 and the upper surface of the sleeper 9 is large, it is difficult for the operator 14 to visually align the tip of the indicator board 7 with the approximate center of the width of the sleeper 9 from the driver's seat of the track straightener 1 due to parallax. Because the error is large and this parallax varies depending on the type of rail, great skill is required, and if the operator is inexperienced, trial and error must be repeated, and setting the tamping position takes time. There was a drawback that it hung. In particular, when the spacing between sleepers is small, such as at a rail joint, if the tamping position is incorrect, the tamping tool 12 and sleeper 9 will interfere, so it takes a long time to set the tamping position.
The drawback was that work efficiency decreased.

The sleeper is attached to the support 39, which is attached to the center of the sleeper, using bolts 40 while adjusting the attachment position in the left-right direction, that is, in the longitudinal direction of the sleeper. Then,
The light source 18 of the floodlight 16 is connected to the cable 24 from the controller.
The track straightener 1 is stopped so that the center of the left and right tamping mechanisms 2 coincides with the center of the width of the sleeper 9, and the lock nut 2 of the floodlight 16 is turned on.
3 and adjust the image of the light source 18 on the top surface of the sleeper 9 using the adjustment tube 22, loosen the fixing bolt 28 of the holder 17 and rotate the mounting ring 26,
Move the image of the light source 18 on the top surface in the width direction of the sleeper, align the center of the image of the light source 18 with the center of the width of the sleeper 9, and tighten the fixing bolt 28 to attach the mounting seat 2.
At the same time, the lock nut 23 of the projector 16 is tightened to fix the adjustment tube 22 to the lower case 20. The adjustment of the tamping position indicating device 15 is now completed, and the track straightening machine 1 can start its work. In this case, when a lamp is used as the light source 18, the image of the light source 18 created on the sleeper surface is created by blurring the focus of the condensing lens 21 using the adjustment tube 22, so that the image of the light source 18 formed on the sleeper surface becomes a circular image 41 as shown in FIG. 7a. Alternatively, by focusing the condensing lens 21 using the adjusting tube 22, it is possible to form an elongated image 42 of the lamp filament as shown in FIG. 7b. In this case, the gap between the image of the light source 18 of the floodlight 16 formed on the upper surface of the sleeper 9 and the upper surface of the sleeper 9 becomes zero, and the worker 1
Since the error caused by parallax when the operator 4 visually observes from the driver's seat is eliminated, the operator 14 can easily and accurately determine the center of the width of the upper surface of the sleeper 9 without requiring any skill.
The center of the image of the light source 18 of the projector 16 formed on the upper surface of the sleeper 9 can be made to substantially coincide with the center. Therefore, if the track straightening machine 1 is stopped so that the center of the image of the light source 18 formed on the upper surface of the sleeper 9 by the projector 16 substantially coincides with the center of the width of the upper surface of the sleeper 9, and the tamping operation is performed, The tamping position can be set in a short time no matter how small the sleeper spacing is that can be tamped by the tamping mechanism 2. In addition, the focus of the projector 16 is adjusted using the adjustment barrel 2.
2 may be driven automatically by an electric motor or the like. Note that a colored lamp may be used as the light source 18 to make it easier to distinguish the image of the upper surface of the sleeper.

上させることができる。 As described above, the tamping position indicating device of the present invention can align the center of the light source image created on the top surface of the sleeper by the projector with the center of the width of the top surface of the sleeper, regardless of the type of rail, and track the track. Since the tamping position of the straightening machine is indicated, errors caused by parallax caused by the large gap between the tip of the indicator board and the top surface of the sleeper, which differs depending on the type of rail, as in the past, are eliminated, and it is possible to adjust the spacing between any sleeper that can be tamped. The correct tamping position can always be detected in a short time and accurately. Therefore, the operator can accurately detect the correct tamping position and perform the tamping work in a short time without requiring any skill, thereby improving work efficiency.
