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： 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： 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。
