    • PURPOSE: A roadbed sound absorption block for an urban railway is provided to reduce repair time and costs by allowing a user to easily change a sleeper, a rail and the damaged sound absorption block. CONSTITUTION: A roadbed sound absorption block(1) for an urban railway comprises a lower block(2) in a gap with a roadbed(A). The lower block is attached to the upper surface of the roadbed, and one side of the lower surface of the sound absorption block is inserted into the upper end with female and male bond(13). A mounting protrusion(21) is formed so that the sound absorption block is mounted on the one end of the upper surface of the lower block. The sound absorption block comprises a protrusion on both ends, and a sound absorption unit is included in the center of the protrusion. A mounting groove(13a) is formed on the lower surface of the sound absorption block, and a connection protrusion(14a) and a connection groove(14b) are included in the center of the both ends of a longitudinal direction.
    • 目的:提供城市铁路的路基吸声块,通过允许用户轻松改变轨枕,轨道和损坏的吸音块,减少维修时间和成本。 构成:用于城市铁路的路基吸声块(1)包括与路基(A)间隙的下块(2)。 下部块附接到路基的上表面,吸音块的下表面的一侧被插入上端,并具有阴和阳键(13)。 安装突起(21)形成为使得吸声块安装在下部块的上表面的一端。 吸音块包括两端的突起,并且在突起的中心包括吸声单元。 在吸音块的下表面上形成安装槽(13a),并且在长度方向的两端的中心包括连接突起(14a)和连接槽(14b)。

    • Disclosed is a rail for a railroad, wherein the rail has a vibration absorbing assembly which can reduce vibration and noise generated when a railroad car driven on the railroad. According to the present invention, the rail for a railroad comprises a head part, a first and a second web part formed at both lower sides of the head part, and a first and a second flange part respectively, horizontally, and oppositely extended from the bottoms of the first and the second web part, wherein at least one of the web part has a surface on which a noise reducing assembly is fixed and mounted by multiple fixing clips. The noise reducing assembly used for the rail and supported to be fixed on the web part by the fixing clips comprises: a damping sheet adhering to the surface of the web part; a vibration absorbing body adhering to the outer surface of the damping sheet; a sound absorbing body positioned outside the vibration absorbing body; and a vibration damping steel sheet positioned outside the sound absorbing body. The fixing clip is an elastic clip made from a high elastic metal material, and partitioned into a first part corresponding to the web part, a second part corresponding to the lower side of the flange part, and a third part facing the first part and corresponding to the front end of the flange part. The first and the second part of the elastic clip form a certain angle so that an elastic force applied to the first part faces the second part, wherein the first part has a front end touching the vibration damping steel sheet which is the outermost member of the vibration absorbing assembly and a curved part formed at a boundary between the third part and the second part houses the side end of the flange part.
    • 公开了一种用于铁路的轨道,其中轨道具有振动吸收组件,其可以减少当在铁路上行驶的铁路车辆时产生的振动和噪声。 根据本发明,用于铁路的轨道包括头部,形成在头部的两个下侧的第一和第二腹板部分,以及第一和第二凸缘部分别水平地并相对地延伸 第一和第二腹板部分的底部,其中腹板部分中的至少一个具有一个表面,在该表面上,降噪组件被固定并由多个固定夹安装。 用于轨道并通过固定夹固定在腹板部分上的降噪组件包括:粘附到腹板部分表面的阻尼片; 粘附在阻尼片的外表面上的振动吸收体; 位于振动吸收体外的吸音体; 以及位于吸音体外部的减振钢板。 固定夹是由高弹性金属材料构成的弹性夹子,并且被分隔成对应于腹板部分的第一部分,对应于凸缘部分的下侧的第二部分和面对第一部分的第三部分和对应的 到法兰部分的前端。 弹性夹的第一部分和第二部分形成一定的角度,使得施加到第一部分的弹性力面向第二部分,其中第一部分具有接触作为第二部分的最外面部件的减振钢板的前端 振动吸收组件和形成在第三部分和第二部分之间的边界处的弯曲部分容纳凸缘部分的侧端。
