Abstract: A track maintenance vehicle having a workhead that is pivotally mounted to the superstructure at its upper end. The workhead includes a blowing tube mounted at its lower end and a vertical cylinder that is selectively extendable and retractable to control the height of the blowing tube. The vehicle includes a control system that controls the height of the blowing tube as well as the left/right and fore/aft positions of the workhead. The track maintenance vehicle further includes an automated height control system that automatically extends and retracts the vertical cylinder to position the blowing tube at a uniform height despite its lateral disposition.

Abstract: A stone metering system for a railroad track maintenance vehicle providing improved accuracy in stone delivery. The system includes a surge hopper, a number of metering augers, and a corresponding number of splitters. The metering augers convey ballast stones from the surge hopper to the corresponding splitters, which divide the stones evenly between a number of blow tubes. The pitch of the auger screw flights is increased from the inlet end of the screw to "expand" the stone and reduce the production of fines. In addition, the diameter of the final screw flight is reduced at the outlet end of the auger to provide a consistent and even flow of stone into the splitters. The splitters are dynamically adjustable to provide even distribution between the blow tubes regardless of the cant to the rails. The desired amount of stone is delivered to the tubes by rotating the auger screw the number of full or partial revolutions associated with the amount. In an alternative embodiment, each of the metering augers is replaced by a conveyor having a belt divided into a series of uniformly sized compartments each conveying the same quantity of stone. The desired amount of stone is delivered to the tubes by driving the belt so that a desired number of compartments are emptied into the splitter.

Abstract translation: 一种用于铁路轨道维护车辆的石材计量系统，可提高石材输送的精度。 该系统包括缓冲料斗，多个计量螺旋钻和相应数量的分流器。 计量螺旋钻将压载物从缓冲料斗输送到相应的分流器，将分离器均匀分布在多个吹塑管之间。 螺旋螺杆螺距的螺距从螺杆的进口端增加到“扩大”石头，并减少罚款的生产。 此外，在螺旋钻的出口端处最终螺杆螺杆的直径减小，以提供一致且均匀的石头流入分流器。 分流器是动态可调的，以提供吹气管之间的均匀分布，而不管轨道的倾斜。 所需量的石头通过旋转螺旋钻螺丝与该量相关的全部或部分转数而传送到管中。 在替代实施例中，每个计量螺旋推运器由具有被分成一系列均匀尺寸的隔室的传送带代替，每个传送相同数量的石头。 通过驱动带将所需量的石料输送到管中，使得所需数量的隔室被排空到分离器中。

Abstract: A rail clip applicator for automatically positioning and installing spring clips into the shoudlers of rail ties for securing rails to the ties. A superstructure rolls along the track from tie to tie carrying a large supply of clips. The superstructure carries two carrier frames. Each carrier frame carries two applicator assemblies disposed on either side of a track rail. Each applicator assembly carries a clip magazine and a head assembly, the head assembly carrying a clip shuttle, a drive block, and a backup block. Clips are loaded into the magazine. From the magazine, clips are serially dispensed to a clip grasping means at the end of a clip shuttle arm. The arm extends to hole the clip in position for being driven into a tie shoulder. The backup block presses against the rear of the shoulder, and the drive block moves the clip from the clip graspign means into the shoulder. The applicator assemblies and head assemblies are moutned such that they automatically position themselves correctly with respect to the tie shoulders. Clips are positioned and installed substantially simultaneously into four shoulders.

Abstract translation: 轨道夹施加器，用于将弹簧夹自动定位并安装到轨枕的挡泥板中，以将轨道固定到绑带上。 一个上层建筑沿着轨道从领带卷起，携带大量的夹子。 上层建筑承载两个承运人框架。 每个承载架承载设置在轨道轨道两侧的两个施加器组件。 每个施加器组件都带有夹子仓和头部组件，头部组件承载夹子梭，驱动块和备用块。 夹子装入杂志。 夹子从夹子中顺序地分配到夹子夹臂的端部处的夹子夹持装置。 手臂延伸到夹子的位置，以便被驱动进入肩带。 支撑块压靠肩部的后部，驱动块将夹子从夹子装置移动到肩部。 涂抹器组件和头部组件被密封，使得它们自动相对于肩部肩部正确地定位。 夹子被定位并基本上同时安装到四个肩部中。
