ASEISMIC DEVICE FOR TRACK MAINTENANCE VEHICLE

PROBLEM TO BE SOLVED: To provide an aseismic device for a track maintenance vehicle which has an extremely simple structure and can be attached to a carriage of the track maintenance vehicle.SOLUTION: An aseismic device for a track maintenance vehicle in which a pair of arms 7 are projected on both sides of a head 6 of a rail 5 from a device body 4, a pair of rollers 9 are attached to a lower end of the arm 7, and the rollers 9 are located adjacent to upper neck parts 8 on both sides of the head 6 of the rail 5. Consequently, even if the vehicle is oscillated due to earthquake, respective rollers 9 are brought into contact with the upper neck parts 8 on both sides of the rail 5 thereby preventing inversion of the vehicle. Further, even during travelling of the track maintenance vehicle, respective rollers 9 are rotated thereby always maintaining a constant distance between themselves and the rail 5, whereby inversion of the vehicle can be reliably prevented.SELECTED DRAWING: Figure 1 【課題】極めて簡単な構造で、保線車両の台車に取付けることができる耐震装置を提供する。【解決手段】装置本体４からレール５の頭部６の両側に一対のアーム７を突出し、そのアーム７の下端に一対のローラ９を取り付け、そのローラ９をレール５の頭部６の両側の上首部８に隣接して配置したもである。そのため、地震により振動しても、各ローラ９がレール５の両側の上首部８に当接して転倒を防止できる。また、保線車両の走行ちゅであっても、各ローラ９が回転してレール５との距離を常に一定に保ち確実に車両の転倒を防止できる。【選択図】図１
