    Abstract: A combination device (102) configured to effect lockout and partial stroke testing for an actuator having a piston rod (104) providing linear motion and connected to a guide block (108) in an actuator, wherein the combination device includes a device housing (102a) having a housing bore, wherein the device housing is adapted to mount on a receptacle on the actuator that aligns a device housing bore coaxially to the translatory motion axis of the piston rod; an extension rod (109) adapted to be attached to the guide block connected to the piston rod; at least two slides or a profiled bore index sleeve (106) disposed in the device housing that when engaged provide means of restraining the movement of the extension rod in a manner that prevents said extension rod from moving and, in use, a driver element of the actuator from rotating relative to an actuator housing; a housing cover mounted over the device housing wherein the housing cover protects and retains the extension rod, and the slides or the index sleeve in the device housing and a spring biased safety pin mounted on the housing cover wherein the spring biased safety pin is configured to prevent unintended actuation of the actuator; and a tubular cover to protect the extension rod.

    Abstract translation: 一种组合装置(102),其构造成对具有提供线性运动并连接到致动器中的引导块(108)的活塞杆(104)的致动器进行锁定和部分行程测试,其中所述组合装置包括装置壳体(102a ),其中所述装置壳体适于安装在致动器上的容器上,其将装置壳体孔与所述活塞杆的平移运动轴线同轴地对准; 延伸杆(109),其适于附接到连接到所述活塞杆的引导块; 设置在所述装置壳体中的至少两个滑块或异形孔索引套筒(106),其在接合时提供限制所述延伸杆的运动的装置,所述装置以防止所述延伸杆运动并且在使用中的驱动元件 致动器相对于致动器壳体旋转; 安装在所述装置壳体上的壳体盖,其中所述壳体盖保护并保持所述延伸杆,以及所述装置壳体中的所述滑块或所述索引套筒以及安装在所述壳体盖上的弹簧偏置安全销,其中所述弹簧偏置安全销被配置为 防止致动器意外致动; 以及用于保护延长杆的管状盖。
