摘要： An improved advancing mechanism for a dual auger continuous miner of the type adapted to be advanced by a pair of anchoring jack assemblies, a pair of cables extending from the anchoring jack assemblies to a pair of winch mechanisms on the sides of the frame. The mechanism includes a mounting arm mounted on each side of the frame for movement about a vertical axis, a telescoping structure extending longitudinally between each mounting arm and the associated anchoring jack assembly and hydraulic piston and cylinder units for effecting the pivotal movement of each arm and the telescoping movement of each telescoping structure.

摘要： The sensing mechanism of the present invention includes a probe electrically connected to a mine roof bolting apparatus and adapted to be embedded within a mine roof to sense any shifting of the apparatus during an operative cycle. The probe is linked to a 360.degree. rotational toggle switch mechanism which controls an alarm means. The probe is pivotably mounted within the roof bolting apparatus and consequently, any effective movement of the apparatus along any direction within a horizontal plane pivotably displaces the probe and actuates the switch mechanism, energizing the alarm. In this manner, personnel are apprised of conditions warranting corrective measures in order to re-position the bolting apparatus or the apparatus may be automatically halted so as to prevent damage from being imparted thereto.
摘要翻译：本发明的感测机构包括电连接到矿山屋顶螺栓连接装置的探头，并且适于嵌入矿井内以感测在操作周期期间设备的任何移动。探头连接到360度旋转拨动开关机构，该机构控制报警装置。探头可枢转地安装在屋顶螺栓装置内，因此，装置沿着水平面内的任何方向的任何有效运动可枢转地移动探头并致动开关机构，从而使报警器通电。以这种方式，人员被告知需要纠正措施的条件，以重新定位螺栓装置，或者可以自动停止该装置，以防止损坏。
