    • Example conveyor systems are disclosed herein. An example conveyor system includes a main conveyor with a frame supporting at least one conveyor extension. Some conveyor extension examples include a powered conveyor belt supported by one or more conveyor sections that are articulated for assisting one or more workers in transferring items (e.g., boxes, parcels, luggage, parts, etc.) to and from the main conveyor. A single main conveyor supports two conveyor extensions mounted alongside each other with someone working at each extension to allow two workers to service a single main conveyor with minimal or no interference, thereby increasing the conveyor system's overall transfer rate. Example conveyor system disclosed herein includes various elements of positional adjustment (e.g., lateral, longitudinal, vertical, angular) to make the conveyor system particularly suited for transferring parcels between a loading dock and the interior of a truck, trailer, aircraft or container.
    • 本文公开了示例性传送系统。 示例性输送机系统包括具有支撑至少一个输送机延伸部的框架的主输送机。 一些输送机延伸示例包括由一个或多个输送机部分支撑的动力传送带,其被铰接用于辅助一个或多个工人将物品(例如,箱子,包裹,行李箱,部件等)传送到主传送带和从主传送带传送。 单个主输送机支撑两个彼此并排安装的输送机延伸件,其中每个延伸部分都有人工作,以允许两个工人以最小的或没有干扰的方式为单个主输送机提供服务,从而增加输送机系统的整体传输速率。 本文公开的示例性输送系统包括位置调整(例如,侧向,纵向,垂直,有角)的各种元件,以使得输送系统特别适合于在装载基座与卡车,拖车,飞行器或容器的内部之间传送包裹。

    • A hydraulic actuator for a hydraulic servomotor (4) is disclosed. The hydraulic servomotor (4) has a first chamber (5) and a second chamber (6) associated therewith. The hydraulic actuator is connected to a fluid source (2) and a fluid drain (3), and it comprises a valve assembly arranged between the fluid source (2) and the fluid drain (3) to control fluid pressures in the chambers (5, 6). At least one auxiliary valve (11) is fluidly connected between the valve assembly and the fluid drain (3), said auxiliary valve(s) (11) being of a kind which is normally closed in a de-energized state. In the case of a power cut off the auxiliary valve(s) (11) will close, thereby preventing fluid flow from the valve assembly towards the fluid drain (3). This causes a servomotor piston member (12) to be hydraulically locked in its instantaneous position, thereby locking the hydraulic servomotor (4). The valve assembly may be designed without taking the locking function into consideration.
    • 公开了一种用于液压伺服电动机(4)的液压致动器。 液压伺服电动机(4)具有与其相关联的第一室(5)和第二室(6)。 液压致动器连接到流体源(2)和流体排放(3),并且其包括布置在流体源(2)和流体排放口(3)之间的阀组件,以控制腔室(5)中的流体压力 ,6)。 至少一个辅助阀(11)流体连接在阀组件和流体排放口(3)之间,所述辅助阀(11)是处于断电状态的常闭状态。 在断电的情况下,辅助阀(11)将关闭,从而防止流体从阀组件流向流体排出口(3)。 这使得伺服电机活塞构件(12)被液压地锁定在其瞬时位置,从而锁定液压伺服电动机(4)。 可以设计阀组件而不考虑锁定功能。
