    • PROBLEM TO BE SOLVED: To lower a noise transmitted to an operator, which is caused by the pulsation of hydraulic oil within junction piping. SOLUTION: A support structure for hydraulic piping includes: a floor plate 15; a driver's seat 35 mounted on the floor plate 15; a pair of operation levers 36 provided at both sides of the driver's seat 35; a matched pair of remote control valves 16, 17 which generate pilot pressure with respect to a hydraulic actuator in response to the input operation of the respective operation levers 36; pipes P1, P2 on the side of a pump and pipes T1, T2 on the side of a tank, which extend respectively from each of the remote control valves 16, 17; the junction piping 24 for joining the pipes P1, P2, to each other and also the pipes T1, T2 to each other, which are led under the floor plate 15 via through-holes 32a, 32b respectively; and an intermediate reinforcing beam 15b which extends in the right-and-left direction, and is fixed to the lower surface of the floor plate 15. The junction piping 24 is fixed to the intermediate reinforcing beam 15b without contacting the floor plate 15. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:降低由连接管道内的液压油的脉动引起的传递给操作者的噪音。 解决方案:液压管道的支撑结构包括:地板15; 安装在地板15上的驾驶员座椅35; 设置在驾驶员座椅35的两侧的一对操作杆36; 一对匹配的一对遥控阀16,17,其响应于相应操作杆36的输入操作相对于液压致动器产生先导压力; 在泵一侧的管P1,P2和分别从每个遥控阀16,17延伸的罐侧的管T1,T2; 用于将管道P1,P2彼此连接的连接管道24以及分别通过通孔32a,32b引导到地板15下面的管道T1,T2彼此连接; 以及沿左右方向延伸并固定到底板15的下表面的中间加强梁15b。接合管道24固定到中间加强梁15b而不与地板15接触。 P>版权所有(C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a floor of a soundproof enclosure with sound absorbing property and to prevent the degradation of sound absorbing property and durability caused by moisture and oil content.
      SOLUTION: A large number of granular materials are laminated in a state of forming clearances among them to form a granular material layer 19, and the granular material layer 19 is held between upper and lower porous panel materials 20, 21 to form a sound absorbing panel 18. The sound absorbing panel 18 is laid on a floor 17 of an engine room used as a soundproof enclosure where an engine or the like which is a sound source is installed, in a state of forming a space S between itself and the floor face. The floor 17 is provided with drip holes 24 communicating with the space S and the outside of the engine room.
