Note that in this state, the collar 63 is connected to the first cylinder. It is adjusted so that it comes into pressure contact with the lower surface of the card 5. Next, attach the clip member 8 to the fitting hole 1. 3, and insert the claw part 39 of the locking tool 34 into the arcuate corner part 17 of the arch 17. Lock in a. On the other hand, the hydraulic oil of the hydraulic pump 42 flows from the three-way valve 58 to the piping 59 and Inlet port 56 of second cylinder 6 from piping 60 via sequence valve 7 sent to. Therefore, there is a delay until the hydraulic oil pressure rises to the specified pressure. occurs. That is, as shown in FIG. 4, the locking mechanism 2 moves upward in the figure and The second cylinder 6 starts operating with the roll 9 and sleeper 10 tightly fixed. As a result, the piston rod 54 moves to the left in FIG. 4, and the receiving plate 38 moves to the left. Press. The arm 33 rotates clockwise around the pin 35. the result , the locking tool 34 connected to the tip side of the arm 33 via a pin 37 also moves to the left. Ru. As described above, the claw portion 39 of the locking tool 34 is connected to the arcuate corner portion 17 of the clamp member 8. a, the clamp member 8 is pushed to the left via the claw 39, and the sensor The taleg 15 is fitted into the fitting hole 13. The center leg 15 is inside the fitting hole 13. When inserted, the locking pin 29 is pressed by the center leg 15 and the spring 3 2 is compressed and stored in the case body 30. The fitting of the clamp member 8 is completed. When this happens, the supply of hydraulic oil to the control mechanism section 4 is stopped. There is no hydraulic oil in the first cylinder 5. As a result, the piston rod 46 is pressed downward by the spring force of the spring 4. Accordingly, the locking mechanism section 2 also descends, returning to the state shown in FIG. 3 again. second cylinder 6 Since the hydraulic oil inside is also released after a certain period of time, the spring 40 and spring The piston rod 54 and arm 33 return to the state shown in FIG. 3 due to the spring reaction force of the rod 55. Return. Thereafter, by repeating the same operation, the clamp member 8 is sequentially moved to the base. It is fitted into the plate 11 side and can tighten the rail 9 and sleeper 10. Device When removing the main body 1 from the rail 9, pull out the lock pin 69 and Rotate the arm 66 180 degrees and lock it in that position with the lock pin 70.
