PROBLEM TO BE SOLVED: To provide an emergency brake device for a track traveling type machine: capable of generating sufficient braking force onto a rail having undulation; capable of preventing overrunning of the track traveling type machine due to strong wind; and capable of suppressing load onto a structure and device itself as little as possible.SOLUTION: On an upper surface of a base block 14, an inclined surface 14a is formed, having an upslope from a center part to both end side in longitudinal direction of a rail 4. The base block 14 is hung from a piston rod 13b with a connecting member 15. An upper edge engaged on the piston rod 13b of the connecting member 15 in a pivotable manner is slidably attached along with a long hole 13c provided on the piston rod 13b. A pressing member 16 is attached on a lower surface of the piston rod 13b. The center part of the base block 14 is pressed via a pressing member 16 with an extending action by the piston rod 13b. A brake pad 12 is constructed so as to be pressed on a traveling wheel rotating surface 4a of the rail 4.SELECTED DRAWING: Figure 4

    【課題】うねりのあるレールに対しても充分な制動力を発生させることができ、強風による軌道走行式機械の逸走を防止し得、更に、構造物並びに装置自体への負荷を必要最低限に抑制し得る軌道走行式機械の非常ブレーキ装置を提供する。【解決手段】ベースブロック14の上面に、中央部からレール4長手方向における両端側へ向け上り勾配となる傾斜面14aを形成し、ベースブロック14を連結部材15にてピストンロッド13bから吊り下げ、連結部材15のピストンロッド13bに枢着される上端をピストンロッド13bに凹設された長孔13cに沿ってスライド自在に取り付け、ピストンロッド13b下面には押圧部材16を取り付け、ベースブロック14の中央部を、ピストンロッド13bの伸長動作により押圧部材16を介して押圧し、ブレーキパッド12をレール4の走行車輪転動面4aに押し付けるよう構成する。【選択図】図4
