Description

  The present invention relates to a vehicle fixing method and a vehicle fixing device, and more particularly to a vehicle fixing method and a vehicle fixing device using a seismic isolation base.

  In recent years, as a preparation for large-scale earthquakes, not only buildings, but also large special machinery and transportation equipment, etc. have been subjected to earthquake-proof measures applying seismic isolation. An example of a seismic measure using seismic isolation is described in Japanese Patent Application Laid-Open No. 8-194092. Japanese Laid-Open Patent Publication No. 8-194092 describes a spent fuel cask using seismic isolation. This spent fuel cask has a cask main body that accommodates a basket formed in a lattice shape, and a support structure that supports the cask main body, and a shock absorber having a seismic isolation function is provided on the lower surface of the support structure. Provided.

  Furthermore, Japanese translation of PCT publication No. 2000-505394 describes a method for loading, fixing and unloading a trailer.

  In each of the above-mentioned conventional technologies, sufficient consideration has always been given to improving the vehicle's seismic isolation effect when a vehicle parked on the seismic isolation foundation vibrates due to an earthquake as described below. Absent.

  If the seismic isolation foundation vibrates due to an earthquake, the vehicle parked on the seismic isolation foundation may vibrate due to the effects of long-period horizontal vibration and significant vertical vibration caused by direct earthquakes. As for it, it is very low, but it is necessary to assume the situation that it rolls over. It is also important that the vehicle can travel quickly after the earthquake has converged.

  In general, the seismic isolation base on which the vehicle is stopped has a flat structure and does not have means for seismically isolating the vehicle. In the seismic isolation foundation with such a structure, when a vehicle stopped on the base starts to vibrate due to an earthquake, there is no means for segregating the vehicle, so the vehicle vibrates vigorously on the base. Or in the worst case, it might be overturned. In particular, a vehicle in a standby state on a seismic isolation base supports its own weight with tires. For this reason, depending on the state of the tire, such as decompression or puncture of the tire pressure, there is a concern that the vehicle posture becomes unstable and the risk of falling during an earthquake increases.

  An object of the present invention is to provide a vehicle fixing method and a vehicle fixing device that can prevent a vehicle from being laterally shifted or rolled over due to seismic force when an earthquake occurs, and that can move the vehicle after the earthquake ends.

A feature of the present invention that achieves the above-described object is that the upper part of the base isolation base in which a plurality of base isolation devices are arranged between the lower base member and the upper base member and attached to the lower base member and the upper base member Both ends of the plurality of first frames inserted below the vehicle body of the vehicle parked on the upper surface of the base member are opposed to each other in the lateral width direction of the vehicle in the plurality of vehicle lifting devices disposed on the upper base member. Removably attached to each vehicle lifting device that makes a pair,
The first frame is lifted by the vehicle lifting device to lift the vehicle,
After the vehicle is lifted, the portions where the movement blocking portions do not exist at both ends of the plurality of second frames that are inserted below the vehicle body and are provided with movement blocking portions on the vehicle body side at both ends, A plurality of vehicle support members disposed on the upper base member are detachably attached to each of the vehicle support members that face each other in the lateral width direction of the vehicle,
The vehicle body is lowered by the vehicle lifting devices, and the vehicle body is supported by the second frame and the vehicle support member in a state where the vehicle body is disposed between the movement blocking portions existing at both ends of the second frame. There is to do.

  According to the present invention, it is possible to prevent the vehicle on the upper base member of the seismic isolation foundation from sideways and rollover due to seismic force when an earthquake occurs, and to easily move the vehicle after the earthquake ends.

The vehicle fixing device 17 according to this embodiment includes a base isolation base 1, a fixing base foundation 5, a vehicle lifting device base foundation 6, a fixing stand (vehicle support member) 8, a vehicle lifting device 13, and a frame 15. The base isolation base 1 has a base isolation base (lower base member) 2, a plurality of base isolation devices 3, and a base isolation base (upper base member) 4. A plurality of seismic isolation devices 3 are arranged on the upper surface of the seismic isolation lower foundation 2 at predetermined intervals and installed on the seismic isolation lower foundation 2. The base isolation base 4 is installed in a plurality of base isolation devices 3 and supported by these base isolation devices 3. The height of the fixing base 5 is higher than the height of the vehicle lifting device base 6. A vehicle support 16a is movable up and down.

  A plurality of fixing base foundations 5 and a plurality of vehicle lifting device base foundations 6 are alternately arranged in a straight line on the seismic isolation upper foundation 4 (see FIG. 4) and installed on the seismic isolation upper foundation 4. The ends of the fixing base foundations 5 and the ends of the vehicle lifting apparatus base foundations 6 arranged alternately in a straight line are in contact with each other. The seismic isolation upper foundation 4 is formed with two rows of parallel arrangements of fixing base foundations 5 and a plurality of vehicle lifting device base foundations 6 (hereinafter referred to as base foundation arrangements) arranged alternately in a straight line. The interval Wb between the base basic arrays arranged in parallel is set to be wider than the lateral width Wv of the vehicle 16 entering between these base basic arrays.

  The vehicle lifting device 13 is disposed on the upper surface of each vehicle lifting device base foundation 6 and is detachably attached to the vehicle lifting device base foundation 6. One frame 15 is arranged for each of the vehicle lifting devices 13 that are installed on the opposing vehicle lifting device base foundations 6 of the base foundation array arranged in parallel and are opposed to each other. Each frame 15 is removably attached to each vehicle lifting device 13 which is installed on each vehicle lifting device base foundation 6 included in a different base foundation arrangement and faces each other.

  A fixing stand 8 is disposed on the upper surface of each fixing base foundation 5 and is detachably attached to the fixing base foundation 5. One other frame 15 is arranged for each of the fixing stands 8 which are respectively installed on the fixing base foundations 5 facing each other in the base base array arranged in parallel and facing each other.

  Each fixing stand 8 is detachably attached to the fixing base 5 at the fixing portion 10. In the fixing portion 10, two elongated holes 10 </ b> A are formed in the base portion of the fixing stand 8. The fixing stand 8 is detachably attached to the fixing base 5 by a stopper 9 inserted into the hole 10A. Since the hole 10A is elongated in the width direction of the vehicle 16, it is easy to attach the fixing stand 8 to the fixing base 5 with the stopper 9 even when the stop position of the vehicle 16 is shifted in the width direction. become.

  A vehicle fixing method using the vehicle fixing device 17 will be described below.

  First, the vehicle 16 is moved onto the seismic isolation upper foundation 4, and is further moved to a vehicle fixing position between two rows of base foundation arrangements to stop. The vehicle 16 has a chassis 16c provided with a plurality of tires 16b, and the vehicle body is provided on the chassis 16c. The frame 15 is inserted below the chassis 16 c of the vehicle 16 in the width direction of the vehicle 16, and the both ends of the inserted frame 15 are disposed on the vehicle lifting device base 6. Each vehicle lifting device 13 is placed on the corresponding vehicle lifting device base foundation 6 at each installation position, and is detachably attached to the vehicle lifting device base foundation 6. The height of the upper end of each vehicle lifting device 13 attached to the vehicle lifting device base foundation 6 is set so that the frame 15 can be disposed between the upper end of the vehicle lifting device 13 and the lower surface of the chassis 16c of the vehicle 16. Then, the vehicle lifting device 13 is operated and adjusted. Thereafter, both ends of the frame 15 inserted below the chassis 16c of the vehicle 16 are placed on the vehicle lifting devices 13 facing each other with the height adjusted, and both ends of the frame 15 are placed on these vehicles. Removably attached to the lifting device 13. Similarly, each frame is removably attached to all the vehicle lifting devices 13 facing each other. Then, all the vehicle lifting devices 13 are operated to raise the attached frames 15, and the frames 15 are brought into contact with the lower surface of the chassis 16 c of the vehicle 16. By operating each vehicle lifting device 13, each frame 15 is further raised to lift the vehicle 16.

  The rear portion of the vehicle 16 is lifted by a plurality of vehicle lifting devices 13 that are removably attached to a rear vehicle lifting device base foundation 7 that is disposed in the vicinity of the rear portion of the vehicle 16 and attached to the seismic isolation upper foundation 4. Specifically, the rear portion of the vehicle 16 is held by a frame 15 that is detachably attached to the upper ends of these vehicle lifting devices 13.

  Each vehicle lifting device 13 is provided with a height measuring device that measures the height of the upper end of the vehicle lifting device 13. Each height measuring device measures the height of the upper end of the vehicle lifting device 13, that is, the height of the lifted vehicle 16, and the measured value of each height is input to a control device (not shown). . Based on each input height measurement value, the control device controls each vehicle lifting device 13 so that the height of the upper end of each vehicle lifting device 13 is the same. By such height control, the posture of the lifted vehicle 16 becomes parallel to the upper surface of the seismic isolation upper foundation 4.

  A hydraulic pump is driven to apply hydraulic pressure to a hydraulic cylinder provided in each vehicle lifting device 13 by an oil supply pipe, and the above-described control device is based on each height measurement value measured by each height measurement device described above. The pressure applied to the hydraulic cylinder is controlled to adjust the amount of movement of the piston rod connected to the piston arranged in the hydraulic cylinder, so that the height of the upper end of each vehicle lifting device 13 is adjusted to be the same. May be. A frame support that forms the upper end of the vehicle lifting device 13 and contacts the frame 15 is attached to the upper end of the piston rod.

  After the vehicle 16 is lifted to the set height, the vehicle 16 is stopped from rising, and the fixing stand 8 is disposed on each fixing base foundation 5 at a predetermined position and can be detached from each fixing base foundation 5. Install. Another frame 15 is inserted below the chassis 16c of the vehicle 16 supported by each frame 15 attached to each vehicle lifting device 13 disposed so as to be opposed to the base base 5 for fixing. Then, it is placed on each of the fixing stands 8 facing each other, and removably attached to these fixing stands 8. After the frames 15 are detachably attached to all the fixing stands 8 arranged so as to face each other, each vehicle lifting device 13 is operated to lower the upper end of each vehicle lifting device 13. Eventually, the chassis 16c of the vehicle 16 comes into contact with the frames 15 attached to the fixing stands 8 facing each other. As a result, each fixing stand 8 supports the weight of the vehicle 16.

  As shown in FIGS. 2 and 3, each frame 15 is provided with a vehicle body receiving portion (movement blocking portion) 15 </ b> A protruding upward at both ends. When the vehicle lifting device 13 is operated to lower the body of the vehicle 16 so that the load of the vehicle 16 is supported by each fixing stand 8, the chassis 16 c of the vehicle 16 has a frame attached to each fixing stand 8. 15 is placed between the vehicle body receiving portions 15A provided at both ends of the 15 and mounted on the frame 15. The vehicle body receiving portions 15 </ b> A provided at both ends of the frame 15 prevent the vehicle 15 from moving in the longitudinal direction of the frame 15. For this reason, when the vehicle 16 is supported by each fixing stand 8, the movement of the vehicle 16 in the longitudinal direction of the frame 15 is restrained by the vehicle body receiving portions 15 </ b> A provided at both ends of the frame 15.

  A procedure for removing the vehicle 16 fixed by the vehicle fixing device 17 in this embodiment from the vehicle fixing device 17 will be described. In order to support the own weight of the vehicle 16 by the vehicle lifting device 13, the vehicle lifting device 13 is operated, and the body receiving portion 15 </ b> A of the frame 15 attached to each fixing stand 8 facing the upper end of the vehicle lifting device 13. The upper end is raised until it is positioned above the upper end. As a result, the vehicle 16 is lifted by the vehicle lifting device 13. When the upper end of the vehicle lifting device 13 rises to that position, the upper end of the vehicle lifting device 13 is stopped and the vehicle 16 is also stopped. The respective frames 15 attached to the respective fixing stands 8 facing each other are removed from the fixing stand 8, and each removed frame 15 is pulled out in the lateral width direction of the vehicle 16. Then, each fixing stand 8 is also detached from the fixing base 5. Thereafter, the vehicle 16 is lowered by operating the vehicle lifting device 13 until each tire 16b of the vehicle 16 comes into contact with the upper surface of the base isolation upper base 4 and the weight of the vehicle 16 is supported by each tire 16b. When each tire 16b of the vehicle 16 contacts the upper surface of the seismic isolation upper base 4, each frame 15 attached to each opposing vehicle lifting device 13 is removed from the corresponding vehicle lifting device 13, and each vehicle lifting The device 13 is removed from the vehicle lifting device base foundation 6. Thereafter, the vehicle 16 can move on the seismic isolation upper foundation 4.

  According to the present embodiment, when the vehicle 16 fixed to the base isolation upper base 4 by the vehicle fixing device 17 vibrates due to the earthquake and an inertia force in the lateral direction of the vehicle is generated, the vehicle 16 faces each other. A horizontal drag acts by the vehicle body receiving portions 15A at both ends of the frame 15 attached to each fixing stand 8, and the lateral displacement of the vehicle 16 can be prevented. Further, even when the vehicle 16 fixed by the vehicle fixing device 17 vibrates due to an earthquake and a falling moment occurs around the center of gravity of the vehicle 16, a reaction force acts by the fixing stand 8 and the frame 15. The vehicle 16 can be prevented from falling. Further, since the interval Wb between the fixing stands 8 that are opposed to each other is wider than the lateral width Wv of the vehicle 16, even when the above-described overturning moment is large, a sufficient reaction to be countered by the fixing stand 8 and the frame 15 is achieved. The force acts and the vehicle 16 can be prevented from falling.

  According to the present embodiment, as described above, the vehicle 16 is more firmly fixed to the seismic isolation upper base 4 by the fixing stand 8 and the frame 15 than before, so that the vehicle 16 may deviate from the stop position during an earthquake. Absent. Further, since the vehicle 16 is supported by the fixing stand 8 and the frame 1, it is not necessary to support the stopped vehicle 16 by the tire 16b. Therefore, a tire such as a change in spring characteristics due to a decrease in the air pressure of the tire 16b and a puncture. The stable fixation of the vehicle 16 to the seismic isolation upper foundation 4 can be realized regardless of the state change of 16b, and the maintainability for the fixed vehicle 16 is also improved.

Finally, the frame 15 is removed from the vehicle lifting device 13, and the vehicle lifting device 13 is further removed from the seismic isolation upper foundation 4 so that the vehicle 16 can move on the seismic isolation upper foundation 4.

  In the present embodiment, each effect produced in the first embodiment can be obtained. Furthermore, in this embodiment, the lower surface of the fixing stand 8 is in contact with the upper surface of the seismic isolation upper base 4, and by the horizontal vibration applied to the seismic isolation upper base 4 by the seismic isolation device 3 when an earthquake occurs, The fixing stand 8 can be sufficiently fixed to the seismic isolation upper base 4 with frictional force. For this reason, in the present embodiment, it is not necessary to attach the fixing stand 8 to the seismic isolation upper foundation 4 using the stopper 9, so that the vehicle 16 and the seismic isolation upper foundation 4 can be easily fixed.
