摘要： A suspension system for an operator's compartment of a mine vehicle is set forth. The mine vehicle is of a type that has a body and operator's compartment positioned adjacent to the body. A guide is attached to the body of the vehicle and a rail is attached to the operator's compartment. This guide and rail arrangement slidably connects the operator's compartment to the body. The guide and rail are arranged to permit the operator's compartment to independently move upward and down in relation to the body. The rail is located in a central portion of the operator's compartment to minimize the angular displacement of the rail with respect to the guide upon rotation of the operator's compartment. This ensures free upward and downward motion of the operator's compartment with respect to the body of the vehicle.
摘要翻译： 阐述了矿用车辆操作室的悬挂系统。 矿车是一种具有身体和操作员室的类型，其位于身体附近。 导轨安装在车身上，导轨安装在操作室内。 该导轨和轨道布置将操作者的隔间滑动连接到主体。 导轨和导轨布置成允许操作者的隔间相对于身体独立地上下移动。 轨道位于操作者舱室的中央部分，以便在操作者舱室旋转时使轨道相对于导轨的角位移最小化。 这确保了操作者室相对于车身的自由上下运动。

摘要： A suspension system for the operator compartment of a mine vehicle suitable for working in underground mines having low head room. A pair of vertically extending guide tracks are rigidly secured to a frame member of the mine vehicle. Each of the track members has associated with it a roller bracket constructed so that all moving contact between the roller bracket and the guide track which guides it is a rolling contact. Each roller bracket includes a projecting stud member of substantial construction which passes through an opening in the rear wall of the operator compartment, the two stud members providing the only points of support for the operator compartment. The operator compartment normally rests on and slides over the floor of the mine and by this arrangement is free to move vertically up and down as the elevation of the mine floor changes or when the bottom of the operator compartment encounters obstacles or debris on the mine floor. One of the openings in the rear wall of the operator compartment is elongated to permit either end of the compartment to move in an arcuate path with respect to the other end so that the compartment may tilt from end to end as required and to prevent binding and sticking of the roller brackets as they move vertically on the guide tracks. Stop means and shock absorbing means are provided to limit movement of the roller brackets in the guide tracks and to cushion the shock transmitted to the operator when the roller brackets impact the stop means.
摘要翻译： 一种用于矿山车辆操作室的悬挂系统，适用于在头部空间较小的地下矿井中工作。 一对垂直延伸的导轨刚性地固定在矿用车辆的框架件上。 每个轨道构件与其相关联的辊支架构造成使得辊支架和引导它的导轨之间的所有移动接触都是滚动接触。 每个滚子支架包括通过操作员隔室的后壁中的开口的实质结构的突出螺柱构件，两个螺栓构件为操作室提供唯一的支撑点。 操作室通常搁置在矿井的地板上并滑动，并且当矿井的高度变化时或者当操作室的底部遇到矿井上的障碍物或碎屑时，这种布置可以垂直上下移动 。 操作员隔室的后壁中的一个开口是细长的，以允许隔室的任一端相对于另一端以弓形路径移动，使得隔室可以根据需要从端到端倾斜并防止结合 滚子支架在导轨上垂直移动时粘贴。 提供止动装置和减震装置以限制滚子支架在导轨中的移动，并且当滚柱支架冲击停止装置时缓冲传递给操作者的冲击。

摘要： A roof bolting system for mines wherein a drill, a resin cartridge, a roof bolt cartridge and a roof bolt feed mechanism are carried on a single indexable head at the end of a boom extending outwardly from an operator's car or carriage. In a roof-bolting operation, the head is initially indexed to a position where the drill bores a hole in the roof of the mine. Thereafter, the head is indexed to the next position wherein a resin cartridge is fed into the drilled hole. Finally, the head is indexed to a third position where a roof bolt is fed into the resin-filled hole and tightened. Thereafter, the head is returned to its original position where the three steps are repeated. A resin cartridge and a bolt cartridge are provided for storing resin tubes and roof bolts such that the respective operations can be carried out automatically without the necessity for having an operator directly beneath the unsupported roof where the roof-bolting operation is occurring.
摘要翻译： 一种用于矿山的屋顶螺栓系统，其中钻头，树脂筒，屋顶螺栓仓和屋顶螺栓进给机构承载在从操作者的车厢或托架向外延伸的悬臂端部的单个可转位头部上。 在屋顶螺栓操作中，头部最初被索引到钻孔在矿井顶部钻孔的位置。 此后，头部被索引到下一个位置，其中树脂盒被送入钻孔中。 最后，头部被索引到第三位置，其中屋顶螺栓被供给到充满树脂的孔中并被紧固。 此后，头部返回到其重复三个步骤的原始位置。 设置树脂盒和螺栓盒，用于储存树脂管和屋顶螺栓，使得可以自动执行各自的操作，而不需要使操作者直接在发生屋顶螺栓操作的无支撑屋顶下方。
