FLUID INJECTION DEVICE FOR SNOW MELTING AND SNOW MELTING DEVICE
To provide a fluid injection device for snow melting that does not need to be removed in advance during track maintenance work for compacting a track bed and re-installed after the work is completed.SOLUTION: A fluid injection device for snow melting connected to ends (15A, 15B) of a pipeline (12) protruding upward from a sleeper for injecting a fluid sent out from the pipeline, includes: a main block (31) formed having an introduction port on the lower surface, a lead-out port on the front surface, and a fluid passage connecting the introduction port and the lead-out port on the inside; and an injection nozzle (23) provided at the lead-out port of the body block. Coupling means is provided at the introduction port on the lower surface of the body block (31) and comprise: a fitting (33) having a female screw part (33a) screwed into a male screw provided at the end of the pipeline formed on the lower inner peripheral surface and a sealing material (33b) attached to the upper outer peripheral surface; and a water pipe (32) having a sleeve (32b) whose upper end is fixed to the introduction port of the body block and which can be fitted to the fitting at the bottom.SELECTED DRAWING: Figure 6
【課題】道床を突き固める保線作業の際に予め除去して作業終了後に再設置する必要のない融雪用流体噴射装置を提供する。【解決手段】下面に導入口を前面に導出口をそれぞれ有し内部に前記導入口と前記導出口とを連通する流体通路が形成されている本体ブロック（３１）と、本体ブロックの導出口に設けられた噴射ノズル（２３）とを備え、枕木の上方へ突出する管路（１２）の端部（１５Ａ，１５Ｂ）に接続されて管路より送出されてくる流体を噴射する融雪用流体噴射装置において、本体ブロック（３１）の下面の導入口には、管路の端部に設けられている雄ネジに螺合される雌ネジ部（３３ａ）が下部内周面に形成され上部外周面にシーリング材（３３ｂ）が装着された結合金具（３３）と、上端が前記本体ブロックの導入口に固着され下部に結合金具に嵌合可能なスリーブ（３２ｂ）を有する導水管（３２）と、を備えた結合手段を設けるようにした。【選択図】図６
