The flexible shaft roof drill is constrained to a frame of the roof bolter for pivoting movement between a rest position and a working position. The roof bolt inserter is mounted on a slide for linear movement and limited rotational movement between a retracted position and an extended position for positioning a roof bolt held by the inserter into registration with a hole drilled by the roof drill.

Field of the Invention The present invention relates to the supporting of underground mine roofs and, more particularly, is directed towards an apparatus for drilling holes in the roof of a mine and for inserting roof bolts into such holes.2. Description of the Prior Art In underground mines, the roof is supported by roof bolts which are inserted into holes drilled into the roof strata. An apparatus for drilling holes having a depth substantially greater than the height of the mine passageway in which the apparatus is located is described in U.S. Pat. No. 4,057,115. An apparatus for inserting roof bolts into the drilled holes is described in U.S. Pat. No. 4,003,233. Although progress has been made in roof bolting apparatus, roof bolting remains one of the most hazardous mining occupations for several reasons. The operator inserting the roof bolt is stationed inby at an area in which the roof is unsupported. It is the operators task to drill and to insert roof bolts in this unsupported area. Consequently, the operator is exposed to the hazard of having sections of the unsupported roof fall on him. Mine personnel have been injured by flying objects from the exposed rotating drill steel and tools employed to tighten the roof bolts. Workers are also exposed to the risk of being caught on and pulled into the rotating portions of the mining apparatus. Attempts to develop roof bolters which are capable of remotely installing bolts have been met with limited success even for the simplest case when the bolts are shorter than the height of the mine passageway. Such attempts have resulted in complex and costly systems which suffer from low reliability due to many moving parts and continual readjustment. A need has arisen for an improved roof bolting system which does not suffer from the heretofore mentioned disadvantages.What is claimed is: 1. An operator controlled roof bolting system for drilling holes in the roof strata of a mine and for inserting roof bolts into the drilled holes while the operator is in a safe area, said system comprising:(a) a frame with an outby operators station; (b) roof drill means for drilling a hole in the roof strata, said roof drill means mounted to said frame for pivotal movement about an axis between a rest position and a working position; (c) first means operatively connected to said roof drill means and said frame for pivotally moving said roof drill means about said axis between said rest position and said working position: (d) roof bolt inserter means for inserting a roof bolt into a hole drilled in the roof strata by said roof drill means, said roof bolt inserter means mounted to said frame for movement between a retracted position and an extended position, said roof bolt inserter means including slide means mounted to said frame for pivoting movement about said axis; and(e) second means operatively connected to said roof bolt inserter means and said frame for moving said roof bolt inserter means between said retracted position and said extended position, said roof bolt inserter means proximate to said operators station when in said retracted position, whereby the operator can place a roof bolt in said roof bolt inserter means while remaining at said operators station. 2. The system as claimed in claim 1 wherein said roof drill means is a flexible shaft roof drill. 3. The system as claimed in claim 1, wherein said roof drill means is a longer-than-seam height drill. 4. The system as claimed in claim 1 wherein said roof bolt inserter means includes a working head mounted to said slide means, said slide means pivotally mounted to said frame, third means operatively connected to said slide means and said frame for pivotally moving said slide means about said axis. 5.

The system as claimed in claim 6 wherein said roof drill means includes a drill and an arm, said drill carried by said arm, fourth actuator means operatively connected to said drill and said arm for moving said drill relative to said arm, said drill constrained for substantially vertical movement relative to said arm, said arm pivotally mounted to said frame for movement about said axis. 8. The system as claimed in claim 7 including torquer means mounted to said working head, said torquer means configured to engage the inserted roof bolt and to tighten the roof bolt to a perdetermined torque. 9.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a roof bolting system which does not suffer from the heretofore mentioned disadvantages and limitations. A further object of the invention is to provide a simple and reliable roof bolting system for remote drilling and insertion of roof bolts, particularly bolts that are longer than the height of the mine passage. Another object of the invention is to provide a simple and reliable roof bolting system with an outby operators station for remote drilling and insertion of roof bolts in which an inserter is moved rearwardly towards an operator for reception of the bolt rather than having the bolt fed forwardly to the inserter from the operator. Such a system includes a rugged mechanism for moving the inserter which is simpler and more reliable than bolt feed systems. Yet another object of the invention is to provide an operator controlled roof bolter with a flexible shaft roof drill or other longer than seam height drill and a roof bolt inserter for drilling and inserting a roof bolt into an unsupported roof of a mine while the operator is outby and is positioned under a supported roof. The flexible shaft roof drill is mounted to a frame of the roof bolter and is constrained for pivoted movement between a rest position and a working position. The roof bolt inserter is configured to bend and feed roof bolts having a length that is greater than the height of the mine passageway. A head of the roof bolt inserter is mounted on a slide for linear movement and limited rotational movement between a retracted position and an extended position in order to align the advancing roof bolt with a hole drilled in the roof strata of the mine by the flexible shaft roof drill. In the retracted position, the inserter is in place to receive a roof bolt from an operator without requiring the operator to leave a supported or safe area. The hole is drilled when the roof drill is in its working position. Upon completion of the drilling step, the roof drill is pivoted to its rest position and the roof bolter inserter is moved to its extended position. A controller is provided for aligning the roof bolt and the drilled hole. A hydraulically actuated plate pushes the inserted roof bolt further into the drilled hole. A torquer engages the inserted roof bolt and tightens the roof bolt to effect the roof support.5大庆石油学院本科生毕业设计(论文)锚杆钻机文件类型和号码:美国专利权 4201270 摘要:操作者控制锚杆钻机通过一个揉性轴带动钻头和一个为实现钻进的锚杆钻机桅杆的相互移动插入一根锚杆在无支护的矿井顶部,这时操作者站在被支护的巷道下面的车体旁边。因为揉性轴转动同时在一个静止位置和一个工作位置之间的运动,锚杆钻机的桅杆被固定在巷道顶部,锚杆钻机钻头安装在可作线性移动的滑道上并且在收缩位置和扩展位置之间转动,用以通过锚杆钻机在巷道顶部钻孔,并且通过螺栓将锚杆紧固在所钻的孔处。 发明家:瑞比斯,威廉一.
