The use method (action) of the above-described slab carrying laid vehicle of the present invention will be described.
As shown in FIG. 7, the slab S ′ is temporarily placed on a temporary placement table H as indicated by a two-dot chain line on the left and right inner sides of the temporary provisional rails r and r.
The towed vehicle 10 is caused to travel along the temporary rails r and r, and the hoisting means 20 is stopped at the upper position of the slab S. The slab S ′ is lifted by the hoisting means 20 (by the lifting bracket 22). When the slab S ′ is lifted by the hoisting means 20, the longitudinal direction of the receiving member 3 is held in parallel with the temporary rail r and does not hinder the hoisting means work.

The slab S 'after lifting the hoisting means 20, to swing the receiving member 3 in the vertical axis L ₃ around. Then, the receiving member 3 has a left and right inward projecting shape below the slab S ′ suspended by the hoisting means 20. Further, the swinging of the receiving member 3 is restricted (fixed) by operating the lock means 50 at a predetermined position (slab stackable position) after the swinging. Then, as indicated by the solid line, the slab S is loaded on the receiving member 3.

The towed vehicle 10 travels on the temporary rails r and r with the slab S placed on the receiving member 3 and transports the slab S to a predetermined facility section. The locking means 50, the receiving member 3, the swinging of the vertical axis L ₃ around is restricted (fixed), inadvertently safely transported while supporting the slab S without swinging. Further, the stopper means 60 (not shown in FIG. 7) prevents sliding (sliding) downward of the receiving member 3.

When arriving at a predetermined facility location, the slab S is lifted again by the hoisting means 20, and then
The lock means 50 is released, the receiving member 3 is swung and stored (released from below the slab S), and the slab S is laid on a predetermined roadbed surface (slab installation surface) T. Note that a plurality of towed vehicles 10 are connected, and a slab S is loaded on each of them, so that a plurality (five in FIG. 1) of slabs S can be laid by one transport.

  By the way, as shown in FIG. 8, in heavy snowy areas such as mountainous areas, the roadbed surface (slab installation surface) T is more than the surrounding surface on which the temporary rail r is provided for snow removal (snow removal) such as snow removal. There is a section that is significantly higher, and in the curve section, a cant amount (crossing gradient) is provided, so that the height difference from the provisional rail r further increases. Specifically, the section with a large difference in height is a section where the height of the installation surface (the highest part 45) of the slab S from the upper surface of the temporary rail r (the contact surface with the wheel 19) is 540 mm or more.

  In other words, when the receiving member 3 is low (at the position of the receiving member 3 as indicated by a two-dot chain line), the receiving member 3 and the transport member are placed on the high roadbed surface T and the slab S "constructed on the buffer material M. The slab S inside may collide (contact).

  When traveling on a curve section (mountain section) in such a heavy snowy region, the receiving member 3 is raised by the lifting means 30. Then, the lower surface of the receiving member 3 rises higher than the high roadbed surface (slab installation surface) T and the already installed slab S ″, and collision (contact) is avoided.

  In addition, the receiving member 3 is smoothly raised to a height (predetermined height) that does not collide with the roadbed surface T or the like by the guide means 40 when it rises. Moreover, it travels while maintaining a low center of gravity. The slab S is maintained in a stable posture (compared to the suspended state) and can easily and safely pass through a curved section of a heavy snowy area.

Further, after laying the slab S, or work when moving into (construction) site, as shown in FIG. 9, left and right of the rail railway vehicle travels on a slab S "in a state of being laid set R, if it is R is laid set, the book rail R, to move the receiving member 3 by lifting means 30 at a position higher than the bed surface of the R a can travel dolly D. Thereafter, the receiving member 3, The vehicle is lowered so as to come into contact with the loading surface side of the carriage D (through a laying material such as sleepers) The frame 1 (the towed vehicle 10) is lifted from the temporary rails r, r as the receiving member 3 is lowered. The frame body 1 is loaded on a cart D (without using another large crane device etc.) The frame body 1 has a strong force (separate from the towing vehicle 11) that travels on the rails R and R. The tow vehicle can be towed, and the towed vehicle 10 moves to the next construction site, etc. faster by using the rails R and R. That.

  Further, the slab S is not stacked on the receiving member 3, and the receiving member 3 is fixed by the locking means 50 in the stored state (a state in which the longitudinal direction is parallel to the temporary rail r) as shown in FIG. That is, an accident in which the receiving member 3 is inadvertently swung and is in contact with other building materials or equipment and a construction site during traveling without loading the slab S is prevented.

  In the present invention, the design can be changed. For example, the towing vehicle 11 provided with a towing drive source is added to the receiving member 3, the elevating means 30, the hoisting means 20, and the guiding means 40 described above. The locking means 50 and the stopper means 60 may be provided.

  As described above, according to the present invention, the portal frame 1 that travels along the temporary pair of left and right temporary rails r and r, and the slab S for the track provided on the frame 1 are placed. Since the receiving member 3 and the elevating means 30 for raising and lowering the receiving member 3 are provided, the height of the temporary rail r is adjusted even if the slab installation surface is a section that is significantly higher than the temporary rail r. There is no need and the slab S can be easily transported. The height of the receiving member 3 can be freely raised and lowered (adjusted) according to the height of the roadbed surface (slab installation surface) T. Even if it is a section where the slab S has already been constructed, it can easily travel. That is, it is possible to cope with both of the forward construction method of laying the slab S while moving forward and the backward construction method of laying the slab S while moving backward. Further, the frame body 1 can be easily loaded on the carriage D that travels along the pair of main rails R and R. That is, the slab carrying laying vehicle of the present invention can be pulled to the main track towing vehicle faster than the towing vehicle 11 by using the carriage D, and can be moved (running) quickly.

Further, a portal frame 1 that travels along a temporary pair of temporary rails r, r, and a slab S for a track that is provided on the frame 1 so as to be swingable around a vertical axis L _3. To be mounted, a hoisting means 20 for loading and unloading the slab S from the receiving member 3, and an elevating means 30 for raising and lowering the receiving member 3. Since the vehicle 10 is provided, it is not necessary to adjust the height of the temporary rail r, and the slab S can be easily transported and laid even if the slab installation surface is a section that is significantly higher than the temporary rail r. The height of the receiving member 3 can be freely raised and lowered (adjusted) according to the height of the roadbed surface (slab installation surface) T. Even if it is a section where the slab S has already been constructed, it can easily travel. That is, it is possible to cope with both of the forward construction method of laying the slab S while moving forward and the backward construction method of laying the slab S while moving backward. Further, the frame body 1 (the towed vehicle 10) can be easily loaded on the carriage D traveling on the pair of main rails R and R. That is, the slab carrying laying vehicle of the present invention can be pulled to the main track towing vehicle faster than the towing vehicle 11 by using the carriage D, and can be moved (running) quickly.

  The elevating means 30 includes a nut member 34 that is rotated by a manual handle 33 and a screw shaft 32 that is screwed into the nut member 34 to move up and down, so that the receiving member 3 can be raised and lowered. Also, the towed vehicle 10 can be made lighter. A driving source such as a generator is not required, so that consumption of energy such as electricity can be reduced and manufacturing costs can be reduced.
