Yes. One end of one lower link 10A is rotatably fixed at a fixed position of the fixed frame 8, and one end of the other lower link 10B can be advanced and retracted along the guide rail 9. Between the left and right groups of the lower links 10A and 10B, a transmission device 13 having a lower cross shaft 12 at both ends is mounted.

  The transmission device 13 includes a drive unit 14 that is a motor with a speed reducer in a case having an internal space, and a pair of left and right synchronous rotary types that are rotationally driven by two transmission mechanisms 15 that are reduction gear mechanisms in the case. A drive nut 16 is provided. When the drive nut 16 is rotated, the pair of left and right screw shafts 17 are driven to advance and retract in synchronization. The tip of the screw shaft 17 is connected to the horizontal shaft 18 to move it forward and backward, and when the horizontal shaft 18 is advanced and retracted, the drive rollers 19 at both ends thereof are advanced and retracted. Each of the lower links 10A and 10B has an arcuate swollen portion, and when the drive roller 19 is pulled in the right direction in FIG. 10A and 10B stand up in the pit 3 with the blades of the coffins widened, and when pushed leftward in FIG. 2, the lower links 10A and 1B are folded down in the pit 3 so that the blades of the coffins are narrowed. It is supposed to be returned to the state.

  The upper link 11 is an X-shaped link connected by an upper intersecting shaft 21, which is also provided in two sets of left and right, and the lower ends thereof are connected to the upper ends of the lower links 10A and 10b. Reference numeral 23 denotes an elevating frame (means for receiving the aircraft from below), which is shaped like a saucer and is connected so that one end of the upper link 11 does not move, while the other end is connected to the upper guide rail 24 via a roller.

In this embodiment, a plurality of ball nut / screw shaft type cylinders 58 are vertically arranged in a pit 59, and a pair of them can be driven synchronously by a common drive shaft 60. Reference numeral 61 denotes a drive unit, and 62 denotes a transmission gear device. The cylinder 58 moves the elevating frame 63 up and down. 64 is a fighter, but it may be a Cessna aircraft, helicopter or other aircraft.

  10 and 11 show another embodiment. In this embodiment, an aircraft such as the fighter 66 is raised to a higher position by a preceding tsunami current t before the tsunami current T attacks, and is evacuated. Reference numeral 67 denotes a base, and 68 denotes a pit, and a lift 70, which is a hollow hermetically sealed float that can be lifted lightly and reliably by a guide roller 69, is provided in the pit 68. The lifter 70 is provided with a plurality of convex portions 71 on the bottom surface thereof, and a water passage 72 is formed between them so that water can reach the bottom surface of the lifter 70. A plurality of action paths 73 are formed at locations facing the water passage 72 in the base 67 so that the preceding tsunami flow t flows with pressure. Further, in the vertical direction orthogonal to the action path 73, the cylinders 74 are arranged so as to be front and rear, and through these cylinders 74, a cushion pipe 75 made of a hollow pipe is inserted so as to protrude upward. Reference numeral 76 denotes a pressure generation reservoir.

The fighter 66 is waiting on the lifter 70 as shown by the solid line in FIG. 10. When the tsunami warning is issued, the fighter 66 does not start rising at that time, and the tsunami flow T actually hits the coast away from the lifter 70. At this time, the preceding tsunami flow t acts on the action path 73, and the ascending action occurs. The tsunami flow t can lift the buffer pile 75 and raise the lifter 70 through the water passage 72 so that the fighter 66 is evacuated to a high level. According to this method, even if the electric motor stops operating due to an earthquake, it is operated using a tsunami current, so that reliable operation is promised.
Although it is conceivable that the lifter 70 eventually comes out of the pit 68 and floats, the buffer pile 75 acts as a resistor at that time, so there is no fear of being swept away.

  FIG. 12 and FIG. 13 show an embodiment in which the tsunami flow into the airfield facility is stopped in front of the airfield 80 on the attack side. A bracket 81 is provided at the front edge of the airfield 80, and a single shaft 82 is provided at the front part through the bracket 81. A plurality of hollow levitation-type protective piles 83 are disposed through the shaft 82 so as to be freely tilted. A plurality of wires 84 are passed through each of the protective piles 83, and a float 85 is attached to the outer periphery of the wire 84 so as to be easily lifted and to enhance the protective effect. Further, a tip float 86 is mounted at the tip of the protective pile 83 so as to be raised by the tsunami flow T and to float up. Reference numeral 87 denotes a water-permeable protective face, such as a metal net, a porous material, or an expanded metal. The protective face 87 may not be provided depending on the number of the wires 84.

  When the tsunami flow T strikes as a first-stage push wave, the protective pile 83 is raised via the tip float 86, and further a large levitation force is obtained via the float 85, and the vertical state is raised. The protection pile 83 is fixed to the bracket 81 with its back so that the tsunami current T and the drifting object are restrained there. The water-permeable protective face 87 suppresses finer mud and the like. This embodiment can be applied in combination with other embodiments shown in FIGS.

  FIG. 14 to FIG. 16 show an embodiment in which the aircraft ascended and lifted on the lifter 90 is prevented from being involved in a fire due to oil such as oil accompanying a tsunami flow that attacks. FIG. 14 is a plan view thereof, and FIG. 15 is a partial cross-sectional view thereof. The lifter 90 is provided on the upper surface of the pit 91, and various mechanisms as in the above-described embodiment not shown can be employed. A circumferential groove 92 is formed on the base 93 so as to surround the outer periphery of the pit 91 and the lifter 90. A protective fence including a film material 94 that can be vertically expanded and contracted along the circumferential groove 92 and a heat-resistant and fire-resistant shielding float 95 that is attached to the upper end of the film material 94 is housed. Reference numeral 96 denotes an anchor for attaching the protective fence to the groove bottom, 97 denotes an automatically removable cover, and auxiliary floats 94a... For promoting floating are attached to appropriate positions of the membrane material 94. Reference numeral 98 denotes an action path, which is a flow path for urging the protective fence to rise as a result of the preceding flow t that is a part of the tsunami flow.

  As shown in FIG. 15, when the tsunami-preceding flow t acts on the action path 98, the shielding float 95 rises while the film material 94 extends as shown in FIG. 16. As a result, the protective fence surrounds the lifter 90, and shields it from oil and the current fire source that are attacked later. In addition, if the water flow part 99 is provided in a part of film | membrane material 94, only a water | moisture content will be flowed and an excessive resistance can be eliminated.

The carrier 107 includes four columns 109 each having a self-propelled traveling roller 108 at the lower end, and a horizontal coupling member 110 that connects the columns 109 at the lower block and the upper end, and a pilot chamber at the front. 111 and an electric winch 112 at the upper end. A receiving frame 113 having a rectangular frame shape is moved up and down by the winch 112, and a hook type engaging tool 114 suspended from the receiving frame 113 can be engaged with the engaged tool 104. The engaging tool 114 can be a mechanism that can be engaged and disengaged with respect to the engaged tool 104 or can be configured to be detachable with an electromagnet. Detailed description of the self-propelled mechanism is omitted. The drive source of the entire carrier 107 including the self-propelled mechanism is preferably an engine that can be activated even during an earthquake, but may be an electric type or a combination type of an engine and electric type. The electric type includes a solar type mounted on the carrier 107 itself.

When the tsunami warning is issued, the lift carrier 107 travels along the guide rail 101 in the direction of the arrow. And if it corresponds to the place which straddles the mounting base 103 containing the helicopter 102 like the virtual line of FIG. 18, the engaging tool 114 will be lowered | hung and engaged with the to-be-engaged tool 104. FIG. Then, if the mounting base 103 is lifted up, it can escape from the tsunami flow that comes after that. After the tsunami flow such as a pulling wave has passed, it can be reused by lowering the mounting table 103. If the support rod 109 and the guide rail 101 can be temporarily locked and unlocked from each other, there is no possibility of the lift carrier 107 itself being swept away or collapsed by a tsunami flow or a drifting material.
The lift carrier 107 may be provided with a fork so as to be inserted under the mounting base 103 and liftable.
In addition, as shown in FIG. 19, it is good also as the lift carrier 107 which can drive | work on the base | substrate 100 freely without a guide rail. In the figure, an electromagnet type is shown as an example of the engaging tool 114. Reference numeral 116 denotes a traveling carriage equipped with a self-propelled tire 117. In this example, a fork type can be adopted.
