Also, over the rail 2L mains L ₁ side, so as to straddle the gap delta _C between the rails 2R mains L ₁ side rail 2L branch line L ₂ side, intercepting member 5C branch line L ₂ side It is attached to the rail 2L of. As a result, as shown by the alternate long and short dash line in FIG. 2, the wheels 1R and 1L of the maintenance vehicle pass from the rails 2R and 2L on the _{branch line L 2} side through the intercepting materials 5A to 5C and the rail 2R on the _{main line L 1 side.} , 2L.

As shown in FIG. 2, and was allowed to enter the maintenance vehicle from the branch line L ₂ to the mains L _1, after is advanced maintenance vehicle from the main line L ₁ to the branch line L ₂ is the chain shown in FIG. 5 When the fixed shaft portion 10a of the lock mechanism portion 10A is the operator retracts, it intercepted material 5A~5C are unlocking in the position of use P _1. Next, when the operator operates the operation command unit 18 shown in FIGS. 1 to 4 and the user selects the end-of-use operation mode, the prime movers 12A to 12C start the operation. At this time, when the user selects the batch operation mode, the prime movers 12A to 12C start the operation at the same time, and when the user selects the individual operation mode, the prime movers 12A to 12C start the operation in an arbitrary order.

When the prime movers 12A to 12C are driven, the driving shaft 12a shown in FIG. 7 rotates in the opposite direction, and the rotating shaft 14c of the mounting portion 14 rotates in the opposite direction via the universal joint portion 15. When the mounting portion 14 rotates around the rotation shaft 14c, the rotation arm portions 7 of the intercepting members 5A to 5C shown in FIGS. 2 and 5 rotate around the rotation shaft 7a. Therefore, as shown in FIGS. 1 and 6, intercepting member 5A~5C rotates from the use position P ₁ to the non-use position P _2, the prime mover 12A~12C stops operating. In a state where the pre-emption material 5A~5C is rotated to the non-use position P _2, is advanced by the operator of the fixed shaft portion 10a of the locking mechanism portion 10B shown in FIG. 6, the fixed shaft portion 10a is intercepted material 5A~5C and hooked, intercepting member 5A~5C is fixed in a non-use position P _2. Therefore, as shown in FIG. 1, the main line L ₁ side of the rail 2R, 2L and the branch line L ₂ of the rail 2R, together with the clearance delta _A, is delta _B is formed between the 2L, mains L ₁ side clearance delta _C is formed between the rails 2R and rail 2L branch line L ₂ side. As a result, as shown in FIG. 1 by the two-dot chain line, the wheels 1R maintenance vehicle during maintenance work, 1L are rolling rail 2R mains L ₁ side, a 2L, after maintenance completion of operating the vehicle wheels 1R, 1L rolls rails 2R, 2L of the main line L ₁ side.

Therefore, for example, the conversion work of the pre-emption device 4 can be reduced by simply laying the automatic conversion device 11 on the rotating arm portion 7 of the existing pre-emption device 4 as a retrofit. Furthermore, just mounting the mounting portion 14 to the point P ₃ of the rotary arm 7 remote from the fulcrum O of the rotating arm 7, it is possible to rotate the rotating arm 7 by a relatively small rotational force. Therefore, the rotary arm portion 7 can be rotated by the small prime movers 12A to 12C. As a result, it is not necessary to modify the basic structure of the stealing device 4, and the automatic conversion device 11 can be installed at low cost.

(3) In this first embodiment, the universal joint portion 15 connects the prime mover shaft 12a and the rotary shaft 14c of the prime movers 12A to 12C. _{Therefore, even if the center line L 12} on the driving shaft 12a side of the prime movers 12A to 12C _{and the center line L 11} on the rotating shaft 14c side of the mounting portion 14 are deviated from each other, the rotational force is applied from the prime movers 12A to 12C to the mounting portion 14. Can be reliably transmitted. Further, even if the height of the sleeper 3 to which the mounting portion 14 is mounted and the height of the sleeper 3 to which the prime movers 12A to 12C are mounted are different, the rotational force is reliably transmitted from the prime movers 12A to 12C to the mounting portion 14. be able to. Similarly, even if the distance between the sleeper 3 to which the mounting portion 14 is mounted and the sleeper 3 to which the prime movers 12A to 12C are mounted is different, the rotational force is reliably transmitted from the prime movers 12A to 12C to the mounting portion 14.
