In this embodiment, as shown in FIGS. 1 and 2, the fixing device 10 is used when the vehicle A is accommodated in the upper and lower stages in the container C, and is attached to the front and rear left and right wheels 30 of the upper stage vehicle A. While fixing one end of three tension applying rods 15 to be described later, and fixing the other end to the ceiling and floor of the container C and pulling firmly from three directions, the vehicle A is placed in the container C. It is designed to be fixed in the raised state. As shown in FIG. 2, each tension applying rod 15 is stretched over the ceiling portion and the floor portion in the container C at an angle in a direction away from the vehicle A from the attachment portion to the wheel 30.

  FIG. 3 is an exploded perspective view of the vicinity of the attachment portion of the fixing device 10 to the vehicle A, and FIG. 4 is a side sectional view thereof. Hereinafter, description will be given using these drawings. The wheel 30 of the vehicle A is fixed to the brake drum 32 by a mounting nut 33 that is screwed into five wheel mounting bolts 31 provided on the brake drum 32 of the vehicle A. Yes. The fixing device 10 according to the present embodiment is configured to be attached to the vehicle A by using the relay nut member 11 that can be screwed to the wheel mounting bolt 31 and is elongated in the axial direction instead of the mounting nut 33. ing. That is, the fixing device 10 covers the three relay nut members 11 and the other end side of the relay nut members 11 at one end with respect to each wheel 30 screwed into the wheel mounting bolt 31 of the vehicle A. A fixed plate 12 having a substantially triangular shape and three connecting members 13 rotatably connected to the fixed plate 12. The fixed plate 12 and the three connecting members 13 are connected to the relay nut member 11. The connecting bolt 14 can be screwed together. The connecting member 13 is connected to a rod-like tension applying rod 15 having screw grooves 15A formed at both ends.

  More specifically, as shown in FIG. 3, the relay nut member 11 is attached by replacing three of the five wheel mounting nuts 33 at the apex of the isosceles triangle and replacing them. Further, the substantially triangular fixing plate 12 addressed collectively to the other end side of the relay nut member 11 is arranged so that each vertex thereof overlaps the relay nut member 11 and is connected to a position overlapping the relay nut member 11. A hole 12 </ b> A that can penetrate the bolt 14 is provided. Further, as shown in the exploded perspective view of FIG. 5, the connecting member 13 has a shape in which an elongated plate is folded back from the center into a U-shape, and a hole 13 </ b> A through which the connecting bolt 14 can be penetrated at both ends. And a hole 13B (through hole of the present invention) having a diameter smaller than the diameter of the flange 18 is provided in the folded portion. ing.

  The relay nut member 11 is set so that the fixing plate 12 is positioned sufficiently away from the wheel 34 and has a length that does not cause the tension applying rod 15 to collide with the vehicle A.

  Similarly, as shown in FIG. 5, the nut member 16 with the flange portion is provided with a flange portion 18 projecting in the radial direction on one end side of the nut that is elongated in the axial direction. A thread groove 16A that can be screwed with the thread groove 15A formed at the end is formed. In addition, a scale 19 is provided near the center of the shaft portion 17 as a measure of the tensile strength of the rod 15 when the tension applying rod 15 is attached. The nut member 16 with the flange portion penetrates the shaft portion 17 into the hole portion 13B from the inside of the folded portion of the connecting member 13. At this time, the hemispherical portion is formed inside the folded portion of the connecting member 13. Thus, the elastic member 20 that can penetrate the nut member 16 and the receiving plate 21 that is plate-shaped and can penetrate the nut member 20 are sandwiched between the folded portion of the connecting member 13 and the flange portion 18 of the nut member 16. (Refer to FIG. 6). The tension applying rod 15 described above is attached to the connecting member 13 so that its length can be adjusted by screwing the screw groove 15A at the end thereof with the screw groove 16A of the nut member 16 with the flange portion.

  On the other hand, FIGS. 8 and 9 are views showing the other end portion (attachment fixing portion to the container C) of the tension applying rod 15, and the other end portion is connected to the connecting member 13 similar to the one end portion described above. Adjustably linked. Further, the other side of the connecting member 13 where the tension applying rod 15 is connected is sandwiched between both ends of the U-shaped member 25 hooked on the hook F provided in the container C so as to be bundled from the outside, and the bolt 26 and a nut 27. As a result, both ends of the tension applying rod 15 are bridged between the container C and the vehicle A.

  The fixing device 10 of this embodiment is as described above, and the operation thereof will be described below.

  When the vehicle A is fixed to the upper stage in the container C, first, among the five mounting nuts 33 screwed into the wheel mounting bolt 31 of the vehicle A, the position 3 that is the apex of the isosceles triangle. The piece is removed, and the relay nut member 11 is attached thereto. Next, a substantially triangular fixing plate 12 is applied so as to collectively cover the other end side of the relay nut member 11, and both end portions of the three connecting members 13 are overlapped in the vicinity of each vertex of the fixing plate 12. The positions of the provided holes 12A and 13A are aligned. Then, the connecting bolt 14 is passed through the holes 12 </ b> A and 13 </ b> A and screwed with the relay nut member 11 to fix the fixing plate 12 and the connecting member 13 to the vehicle A.

  In this state, the vehicle A is moved into the container C and lifted to a predetermined position by a forklift or the like. And the elastic member 20 and the receiving plate 21 are arrange | positioned inside the folding | returning part of the connection member 13, and the nut member 16 with a collar part is penetrated from the receiving plate 21 side. Then, the tip of the nut member 16 with the flange portion is in a state of protruding to the outside of the folded portion of the connecting member 13. Here, one end of the tension applying rod 15 is screwed and attached, and the other end is similarly attached to the connecting member 13 previously attached to the ceiling portion and the floor portion in the container C. In this state, the vehicle A is in a state of floating in the container C. By further rotating the tension applying rod 15 in the radial direction, the tension strength between the container C and the vehicle A is gradually increased. And the fixation can be made stronger. At this time, since the scale portion 19 is provided on the shaft portion 17 of the nut member 16 with the flange portion, the degree of tension of the tension applying rod 15 is determined by looking at the scale 19. It is easy to check whether the tension of the book is balanced.

  After the adjustment is repeated until the tensioning rods 15 stretched in three directions are equal in tension and strong enough to prevent the vehicle A from swinging, the vehicle A can be removed from the container by pulling out the forklift. It floats in the air while being firmly fixed in C.

  As described above, when some impact or vibration is applied to the container C during transportation of the vehicle A fixed in the container C using the fixing device 10 of the present embodiment, the fixing device 10 operates as follows. That is, since the vehicle A has four wheels (brake drums) at the front, rear, left and right, which are firmly pulled and fixed from the three directions, the container C does not shake as much as a swing in the container C as in the prior art. Further, since the connecting member 13 and the tension applying rod 15 do not directly hit the vehicle A due to shaking, the vehicle A can be prevented from being damaged. In addition, when a large compressive force is applied in the axial direction of a rod-like member such as the tension applying rod 15, the rod 15 generally buckles and may be bent greatly. In the device 10, a mechanism for releasing the compressive force in the axial direction of the rod 15 is provided at both ends of the tension applying rod 15. Specifically, by increasing the tension strength of the tension applying rod 15, the flange portion 18 of the nut member 16 with the flange portion is pressed against the elastic member 20 side. 16) is movable in a direction away from the elastic member 20, and when a large compressive force is applied in the axial direction of the rod 15, the nut member 16 with the flange and the rod 15 fixed thereto are elastic. By moving to the opposite side of the member 20, the force can be released without directly receiving a large compressive force. Therefore, the tension applying rod 15 is not bent. Further, even when a force with an angle deviating from the axial direction of the tension applying rod 15 is applied, the connecting member 13 to which the rod 15 is connected is attached to the fixed plate 12 so as to be pivotable. 15 can escape without directly receiving the force.

  As described above, according to the fixing device 10 of the present embodiment, the vehicle A is firmly fixed in a state of being floated in the container C, and the force is applied without bending the tension applying rod 15 when a large force is applied. It shows an excellent effect of being able to escape.
