The cylinder portions of the hydraulic cylinders 74 and 76 are vertically fixed to the vertical members 70 and 72 via mounting members. Plate-shaped pressure receiving members 78 and 80 are rotatably supported on shafts 82 and 84 at the ends of the rods of the hydraulic cylinders 74 and 76, respectively.
[0010]
Next, the operation of the present embodiment will be described.
Each of the rail bodies 10 of the pair of heavy load moving support devices 6 and 6 is set at right angles to the longitudinal direction of the bogie 4 of the wagon 2. As shown in FIG. 4, the centers of the pair of movable tables 50 are set on the central axis L1 of the carriage 4. The concrete pillar 86 for the viaduct is placed on the moving bases 50, 50 and is firmly fixed to the moving bases 50, 50. When moving the column 86 from the wagon 2 to another place, first, the horizontality of the movable bases 50 and 50 is adjusted. When the wagon 2 is inclined, the hydraulic cylinder 58 is driven to project or retract the rod.
[0011]
When the rod of the hydraulic cylinder 58 projects leftward in FIG. 2, the upper part of the connecting piece 60 is pushed leftward by the rod, the shaft 48 rotates counterclockwise, and the carriages 50, 50 2 is tilted counterclockwise about a shaft 48 parallel to the longitudinal direction. When the rod of the hydraulic cylinder 58 retreats rightward in FIG. 2, the movable tables 50, 50 tilt clockwise about the shaft 48. In accordance with the inclination of the wagon 2, the inclination of the movable tables 50, 50 is adjusted, and the movable tables 50, 50 are adjusted horizontally. Thus, the column 86 is stably supported on the movable bases 50, 50, and the column 86 can be safely lifted and transferred by the crane.
[0012]
Next, the column 86 is moved in a direction deviated by a predetermined distance from the center axis of the overhead line so that the crane performing the transfer operation does not contact the overhead line above the freight car 2. The center axis of this overhead wire is located at the same position as the axis indicated by L1 in FIG. This moving operation is performed by driving the movable carriages 50, 50 from the center in the width direction of the carriage 4 by the motor 36 to the side. The driving of the motor 36 rotates the sprocket 38, and the movable tables 14, 14 are guided by the rail bodies 10, 10, and move rightward in FIG. One end 14a of the moving bodies 14, 14 moves a predetermined distance outward of the carriage 4, as indicated by a virtual line in FIG. 2, and the center of the column 86 on the moving tables 50, 50 moves a predetermined distance from the center axis L1 of the overhead line. At this point, the driving of the motor 36 stops.
[0013]
In this state, as shown in FIG. 2, one end of each of the movable bases 50 protrudes outside the carriage 4 by a predetermined distance. Next, the horizontal members 66 and 68 are manually pushed into the moving bodies 14 and 14, respectively, and the vertical members 70 and 72 are arranged adjacent to one ends of the corresponding moving bodies 14 and 14, respectively.
Next, the hydraulic cylinders 74 and 76 are driven, and the pressure receiving members 78 and 80 are pressed against the ground or a sleeper (not shown). Thus, the vertical members 70 and 72 support the loads of the movable tables 50 and 50 outside the wagon 2. Next, the column 86 on the movable bases 50, 50 is lifted by the crane, and is moved from the carriage 4 to a predetermined place. When the transfer operation of lowering the column 86 from the carriage 4 is completed, the hydraulic cylinders 74 and 76 are driven to raise the pressure receiving members 78 and 80 from the sleepers or the ground by a predetermined distance.
[0014]
Next, when the motors 36 are driven to move the movable carriages 50, 50 to the original center position on the carriage 4, when the vertical members 70, 72 are locked to the carriage 4, the horizontal members 66, 68 are engaged. In a state where the interlock with the moving tables 50, 50 is stopped and the horizontal members 66, 68 are stopped, the moving bodies 14, 14 move in the direction of the original positions, and the horizontal members 66, 68 move to the original positions. , 14 are withdrawn a predetermined distance as shown in FIG. The horizontal members 66 and 68 are fixed to the carriage 4 by appropriate fixing means (not shown) so that the horizontal members 66 and 68 do not slide in the protruding direction from the moving bodies 14 and 14 when the wagon moves.
[0015]
