摘要： A switch machine for moving railroad switch points. The switch machine includes a switch stand adapted to be connected to the railroad switch points. The switch stand includes a rotatable hub which is selectively rotatable to throw the switch points. A rotary actuator includes a rotatable pinion that is coupled to the hub of the switch stand. A hydraulic pump and a valve are in fluid communication with the rotary actuator and selectively control the direction of rotation of the pinion. A first proximity sensor and a second proximity sensor are provided to sense the position of the pinion and hub. When the pinion and hub are rotated to a first position to move the switch points to a first switch point position, the first sensor will deactivate the hydraulic pump. When the pinion and hub rotate the switch points to a second switch point position, the second proximity sensor will deactivate the hydraulic pump.

摘要： A railroad switch stand for actuating a rail switch between open and thrown positions includes, in one embodiment, an upstanding frame supporting a handwheel at approximately chest height for movement between a first position enabling manual rotation of an upstanding throw shaft to actuate a horizontal rail switch throw rod, and a second position enabling powered rotation of the throw shaft to open or throw the rail switch points. In alternative embodiments, low profile railroad switch stands are adapted for interconnection to a rail switch throw rod through fluid pressure or electric motor actuators and associated constant force spring actuators in a manner to apply a substantially constant force to the throw rod in maintaining the rail switch in open or thrown positions. The constant force spring actuators provide overload protection and automatic reset in the event a train runs through a rail switch lined against it. In all embodiments, a switch target is positively interconnected to the throw rod and provides a visual indication of the exact position of the rail switch.
摘要翻译：在一个实施例中，用于致动开放和抛出位置之间的轨道开关的铁路开关支架包括在大致胸部高度处支撑手轮的直立框架，用于在第一位置和第二位置之间移动，所述第一位置使直立的投掷轴能够手动旋转以致动水平轨道开关投掷杆，以及第二位置，使得投掷轴能够动力旋转以打开或投掷轨道开关点。在替代实施例中，低轮廓铁路开关支架适于通过流体压力或电动马达致动器和相关联的恒力弹簧致动器与轨道开关投掷杆互连，以便在维持轨道开关在开放或抛出的位置。恒力弹簧执行机构提供过载保护和自动复位，在列车通过内置导轨开关的情况下运行。在所有实施例中，开关目标正确地互连到投掷杆并且提供轨道开关的精确位置的可视指示。

摘要： The present invention relates to a hydraulic apparatus for moving railroad switch points from side-to-side. The apparatus has a hydraulic cylinder operatively connected to the switch points to move the switch points from side-to-side in fluid communication with a power source. The direction of the movement of the switch points is controlled by a valve positioned in fluid communication between the power source and the hydraulic cylinder. The direction of movement of the hydraulic cylinder and, consequently the switch points, is determined by the direction the valve is moved. In another aspect, the present invention has a hydraulic rail pump in fluid communication with the accumulator for storing hydraulic power generated by the rail pump activated by the wheels of passing trains, and a safety reservoir in fluid communication with the accumulator for storing hydraulic power beyond the capacity of the accumulator.
摘要翻译：本发明涉及一种用于从一侧到另一侧移动铁路切换点的液压装置。该装置具有可操作地连接到开关点的液压缸，以使切换点从一侧到另一侧与电源流体连通。开关点的移动方向由位于动力源和液压缸之间流体连通的阀门控制。液压缸的移动方向，因此切换点由阀门移动的方向决定。在另一方面，本发明具有与蓄能器流体连通的液压轨道泵，用于存储由通过列车的车轮启动的轨道泵产生的液压动力，以及与蓄能器流体连通的用于存储液压动力的安全储存器蓄能器的容量。
