Abstract:
An operator controlled roof bolter with a flexible shaft drill and a roof bolt inserter for drilling and inserting a roof bolt into an unsupported roof of a mine while the operator is positioned at an outby station under a supported roof. 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.

BACKGROUND OF THE INVENTION
1. 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 operator's 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 operator's 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:

(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 operator's station when in said retracted position, whereby the operator can place a roof bolt in said roof bolt inserter means while remaining at said operator's 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.

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 operator's 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.

2、之前的技術(shù)描述
在地下礦井中，巷道頂部支護(hù)是通過插入戶頂土層鉆孔中的錨桿來實(shí)現(xiàn)的。機(jī)械裝置能夠鉆孔的足夠深度，要比機(jī)械裝置所在的礦井出口處的高度大，這時(shí)有美國(guó)的一項(xiàng)專利所描述的，專利號(hào). 4,057,115。在美國(guó)專利號(hào)為4，003，233的專利中描述到機(jī)械裝置能夠?qū)㈠^桿插入鉆孔中。
雖然進(jìn)步已經(jīng)在錨桿鉆機(jī)裝置中表現(xiàn), 但是仍然有一些理由被認(rèn)為錨桿支護(hù)采礦職業(yè)中最危險(xiǎn)的。插入戶頂錨桿的操作者站在沒有護(hù)頂支護(hù)的區(qū)有附近。它是操作者在這鉆孔而且插入錨桿不支護(hù)的區(qū)域.。結(jié)果, 操作者有遭受被不支護(hù)的護(hù)頂砸在身上甚至送命的危險(xiǎn).。我本人就受過傷，是由飛來的鉆鋼和用于緊固錨桿的工具所造成的，工人也遭受過危險(xiǎn)而且滑進(jìn)了采礦裝置的旋轉(zhuǎn)部分。

本發(fā)明是預(yù)防錨桿鉆機(jī)不受前面所提到的不利因素和限制的目標(biāo)。發(fā)明的進(jìn)一步目標(biāo)是將提供一套簡(jiǎn)單而且可靠鉆進(jìn)和插入錨桿的系統(tǒng)，特別是錨桿的長(zhǎng)度長(zhǎng)于礦井出口的高度的情況。
發(fā)明的另一個(gè)目標(biāo)是提供一套簡(jiǎn)單而且可靠的錨桿鉆機(jī)系統(tǒng)，該系統(tǒng)使操作者可以實(shí)現(xiàn)遠(yuǎn)距離的鉆進(jìn)和插入錨桿，在這個(gè)過程中隔板移動(dòng)到操作者的后方緊固錨桿，這要比錨桿在操作者的前方插入安全。這樣的一套系統(tǒng)包括一個(gè)移動(dòng)隔板，該粗糙的機(jī)械裝置要比以前錨桿插入系統(tǒng)簡(jiǎn)單而且更可靠。
然而發(fā)明的另一個(gè)目標(biāo)是為操作者提供可以通過柔性軸鉆頭控制錨桿鉆機(jī)或是控制另一個(gè)比縫合線高度鉆孔機(jī)和一個(gè)錨桿隔板長(zhǎng)，為鉆進(jìn)和插入錨桿進(jìn)入礦井的不支護(hù)的護(hù)頂土層，這時(shí)操作者遠(yuǎn)離而且置于有支護(hù)的護(hù)頂下面。揉性軸鉆頭安放在錨桿鉆機(jī)的框架上而且被限制在一個(gè)休息位置和一個(gè)工作位置之間轉(zhuǎn)動(dòng)，錨桿鉆機(jī)隔板配置成彎曲而且進(jìn)給錨桿有一個(gè)能夠順利通過礦井出口高度的長(zhǎng)度。錨桿鉆機(jī)隔板的頭部固定在可作線性移動(dòng)的滑道上，用以限制一個(gè)被撤回的位置和一個(gè)擴(kuò)大的位置之間的回轉(zhuǎn)的運(yùn)動(dòng)為了要用被有柔性鉆頭在礦井的護(hù)頂土層鉆孔并且在每個(gè)孔中插入錨桿。在被撤回的位置中，隔板不需要操作者直接參與適當(dāng)?shù)貙㈠^桿移開從一被支護(hù)的位置，它來自一個(gè)操作員的錨桿鉆機(jī)或安全的區(qū)域.。當(dāng)鉆機(jī)鉆頭在它的工作位置時(shí)錨桿孔被鉆進(jìn)。在完成鉆進(jìn)步驟的基礎(chǔ)上，鉆機(jī)鉆頭轉(zhuǎn)動(dòng)到它的休息位置，而且鉆機(jī)隔板被搬到它的廣大位置。 一個(gè)控制器為排列錨桿和鉆孔而提供。 一個(gè)液壓動(dòng)力盤推動(dòng)錨桿插入更深的錨桿孔中。錨桿鉆機(jī)隔板預(yù)定的轉(zhuǎn)矩和鉆機(jī)夾緊力來實(shí)現(xiàn)錨桿支護(hù)。
