The utility model discloses a city rail air tight double open plug door, which includes a left door fan, a right door fan, a bearing drive mechanism, a door carrying frame, a balance wheel component, a lower arm assembly and a door frame pressure. The bearing drive mechanism is mounted above the body door frame, and the left and right door fans are connected to the bearing drive mechanism by carrying the door frame and carrying the driving mechanism. There are two lower guideways under the left and right door fans. The left and right door fans slide along the upper guide and the lower guideway driven by the load-bearing drive mechanism to realize the opening and closing action, which consists of a double opening system; the balance wheel assembly is installed on the two sides of the doorframe, and the lower swing arm assembly is installed at the bottom end of the door frame. The door frame is mounted around the door frame; the left and right door fans include the door plate, the glue bar and the rubber bar assembly; the glue bar is installed on the side side of the door plate, and the installation slot of the glue bar assembly through the glue bar is fixed on the door plate. The utility model has good sound insulation and heat insulation effect, improves riding comfort and improves airtightness.
【技术实现步骤摘要】
一种城轨气密双开塞拉门
本技术涉及一种采用城轨气密双开塞拉门,属于城市轨道交通
技术介绍
与移门和外挂门相比,塞拉门综合性能较好,具有较好的密封性和隔音效果,在城市轨道交通领域,得到了较为广泛的应用。然而,传统城轨塞拉门系统重量大,能源消耗高,而且较高速运行时车内外压差变化使得双开门系统气密性不足、噪音偏大,已经严重制约了其进一步发展,轻量化、气密性能提升成为城轨塞拉门的重要发展方向。专利号“201220021950.9”,名称为“一种双开密闭门系统”的技术专利,在左门扇和右门扇的后档处设两个压紧锁、前档下部也设有压紧锁,四周设密封胶条,护指胶条设为対插式,从密封胶条和额外约束两个方面实现了双扇塞拉门的气密性要求,但其四周密封胶条形式未指明,如果采用普通的水密胶条根本无法满足气密要求,另外,忽略了气密性实现的一个非常重要的方面,即门板的刚度,由于门板在受大气压力情况下会发生一定程度的弯曲,这就会影响到车门密封面与密封胶条的结合,若变形力超过密封胶条的结合力,就会破坏密封胶条的密封性能,气密性根本无法实现,因此门板必须有增加刚度的措施。
