Description
- The present invention relates to a rock bolting machine that includes a vehicle and is used to drill a bolt hole and install a rock bolt in a roof of an underground space. More particularly, the present invention relates to a rock bolting machine that uses a travelling boom to support a rock bolting apparatus.
- Rock bolts are installed in the roofs of mines, tunnels and other underground spaces for securing the roof of the mine in place and preventing the roof from collapsing when the mine is in use and workers may be in the mine. First, a bolt hole is drilled in the mine roof and then a rock bolt is secured in the drilled bolt hole.
- It is common for the rock bolts to be installed by using a vehicle with a rock bolting apparatus attached to a boom. The rock bolting apparatus can be raised or lowered using the boom so that the rock bolting apparatus can come into contact with the roof of the mine to drill a bolt hole and install a rock bolt in the drilled bolt hole. The purpose of the boom is to position the rock bolting apparatus well out in front of the vehicle so that the vehicle and the operator of the vehicle can remain under a portion of the mine roof that has already been rock bolted and secured.
- However, because the underground spaces where the rock bolts are being installed are often narrow and tight, it is often hard to maneuver a vehicle through these underground spaces. While having a boom extending far out in front of the vehicle with a rock bolting apparatus attached to the end of the boom is useful to allow the vehicle to remain under a portion of the mine roof that has already been bolted while a rock bolt is being installed, this long boom can make it even more difficult to maneuver the vehicle around underground and in other confined spaces.
- In one aspect, a rock bolting machine for installing a rock bolt in a roof of an underground space is provided. The rock bolting machine can include a vehicle having a direction of travel and a rock bolting apparatus having a drilling portion adapted to drill a hole in the roof of the underground space and a bolting portion adapted to install a rock bolt in a hole created with the drilling portion. A boom can be provided between the vehicle and the rock bolting apparatus with a distal end of the boom connected to the rock bolting apparatus and a proximal end moveably connected to the vehicle.
- In a further aspect, the proximal end of the boom is moveable relative to the vehicle, substantially in the direction of travel of the vehicle.
- In a further aspect, movement of the proximal end of the boom in the direction of travel of the vehicle causes the distal end of the boom to move the same distance in the direction of travel of the vehicle.
- A preferred embodiment of the present invention is described below with reference to the accompanying drawings, in which:
-

When the bolt hole has been drilled, thedrill bolt mast 130 can then be rotated around thepivot point 132 until the boltingportion 160 lines up with the bolt hole and the boltingportion 160 used to install a rock bolt in the bolt hole. - The
drilling portion 140 can have adrill guide frame 142 that can be moved vertically relative to theframe 135 of thedrill mast 130 as well as guide adrill rod 144 that can be moved vertically relative to thedrill guide frame 142 as thedrill rod 144 is rotated and moved upwards relative to thedrill guide frame 142. Thedrill guide frame 142 can extend vertically and be movable so that a top end of thedrill guide frame 142 can be positioned against thetop plate 136 of thedrill bolt mast 130 or moved downwards to create a space between the top of thedrill guide frame 142 and bottom of thetop plate 136. - A
foot plate 146 can be provided on the bottom of thedrill guide frame 142 to protect the elements of thedrilling portion 140 from being damaged if the bottom of thedrilling portion 140 accidentally comes into contact with the floor of the underground chamber while therock bolting apparatus 50 is being maneuvered into place. - The
drilling portion 140 can both rotate thedrill rod 144 and move thedrill rod 144 upwards relative to thedrill guide frame 142 and theframe 135 of thedrill bolt mast 130 to drill a bolt hole where the rock bolt will be installed. - The bolting
portion 160 of therock bolting apparatus 50 is used to fasten arock bolt 164 into the bolt hole that has been created by thedrilling portion 140. The boltingportion 160 can have abolting guide frame 162 that allows abolting assembly 170 to move vertically along boltingguide frame 162. Thebolting guide frame 162 can extend vertically and be movable vertically relative to theframe 135 of thedrill bolt mast 130 so that a top end of thebolting guide frame 162 can be positioned against thetop plate 136 of thedrill bolt mast 130 or moved downwards to create a space between the top of thebolting guide frame 162 and bottom of thetop plate 136 of thedrill bolt mast 130. - A
foot plate 166 can be provided on the bottom of thebolting guide frame 162 to protect the elements of the boltingportion 160 from being damaged if the bottom of the boltingportion 160 accidentally comes into contact with the floor of the underground space while therock bolting apparatus 50 is being maneuvered into place. - The bolting
portion 160 can both rotate therock bolt 164 and move therock bolt 164 upwards relative to thebolting guide frame 162 and theframe 135 of thedrill bolt mast 130 to insert therock bolt 164 in the bolt hole drilled by thedrilling portion 140 of thedrill bolt mast 130. Typically, therock bolt 164 is first moved upwards into the drilled bolt hole and then only rotated by the boltingportion 160 when therock bolt 164 has been inserted all the way into the bolt hole to secure therock bolt 164 in the bolt hole. - In operation, the
rock bolting apparatus 50 can be positioned against the roof of the underground space. Once in place against the roof of the underground space, thepick 112 in thepick mast 110 can be used to hold therock bolting apparatus 50 against the roof while therock bolting apparatus 50 is being used to drill a bolt hole and install arock bolt 164 in the bolt hole by extending thepick 110 out of the top of thepick guide 114 and forcing it into the roof of the underground space. By engaging the roof in this manner, the extendedpick 110 can hold therock bolting apparatus 50 in place and prevent it from shifting its position on the roof while the bolt hole is being drilled and therock bolt 164 is being installed in the drilled bolt hole. - Once the
rock bolting apparatus 50 is secured in position using thepick 112, thedrilling portion 140 on thedrill bolt mast 130 can be used to drill a bolt hole. Thedrilling rod 144 can be rotated and forced upwards to bore the bolt hole in the roof of the underground space. - When the bolt hole has been drilled by the
drilling portion 140, thedrill rod 144 can be retracted from the bolt hole it has drilled and the boltingportion 160 can then be used to install arock bolt 164 in the bolt hole. Thedrill bolt mast 130 can be pivoted aroundpivot point 132 usingactuator 134 while thepick 112 keeps therock bolting apparatus 50 in the same position relative to the roof. When thedrill bolt mast 130 has pivoted so that therock bolt 164 is positioned under the bolt hole, the pivoting of thedrill bolt mast 130 can be stopped and thedrilling portion 160 of therock bolting apparatus 50 can be used to install therock bolt 164 in the bolt hole. - With the
rock bolt 164 positioned under the bolt hole, the boltingportion 160 can move therock bolt 164 upwards to insert it in the drilled bolt hole. Once therock bolt 164 is inserted into the bolt hole, therock bolt 164 can be torqued to secure it in the bolt hole. - Referring again to
FIG. 1 , theboom 30 can be attached to thevehicle 20 at aproximal end 32 of theboom 30 and to therock bolting apparatus 50 at thedistal end 34. - The
boom 30 can be formed of a number of telescoping sections 31 (as shown inFIGS. 8 and 9 ) so theboom 30 can be telescopically extended or retracted, allowing the length of theboom 30 to be increased or decreased. Theproximal end 32 of theboom 30 can also be attached to thevehicle 20 so that theproximal end 32 of theboom 30 can move relative to thevehicle 20 in addition to allowing theboom 30 to be pivoted from side to side and up and down. -
FIGS. 4 and 5 illustrate views of theproximal end 32 of theboom 30. Theproximal end 32 of theboom 30 can include aconnection frame 302 that houses aboom motor 304, such as a hydraulic motor, attached to aconnection panel 306. Theboom motor 304 is operative to rotate theconnection panel 306 relative to theconnection frame 302. Theproximal end 32 of theboom 30 can be attached at apivot point 308 to theconnection panel 306. By using theboom motor 304 to rotate theconnection panel 306 relative to theconnection frame 302, theboom 30 can be pivoted from side to side relative to thevehicle 20. - By having the
proximal end 32 of theboom 30 attached to thepivot point 308 on theconnection panel 306, theboom 30 can be pivoted upwards and downwards relative to theconnection frame 302. Anactuator 310, such as hydraulic cylinder, can be provided between theconnection panel 306 and theboom 30 to pivot theboom 30 upwards and downwards around thepivot point 308. - The
connection frame 302 can be attached to atrack 320 having afirst end 322 and asecond end 324 so that theconnection frame 302 and therefore theproximal end 32 of theboom 30 can move relative to thevehicle 20.Brackets 330 can be provided on theconnection frame 302 that are slidably attachable to a pair ofrails 332 on thetrack 320 so that theconnection frame 302 can slidably move along thetrack 320. - A
rack 340 can be provided running along the length of thetrack 320 that meshes with apinion 342 attached to theconnection frame 302. Apinion motor 344 can be provided to rotate thepinion 342. In this manner, thepinion motor 344 can be used to rotate thepinion 342 which will mesh with therack 340 and thereby move theconnection frame 302 along thetrack 320. - Stop
brackets 350 can be positioned at thefirst end 322 of thetrack 320 to stop theconnection frame 302 when it reaches thefirst end 322 of thetrack 320. - Referring again to
FIG. 1 , thecab 16 of thevehicle 20 can be offset to one side of thevehicle 20 with thecab 16 offset to one side of a center line of thevehicle 16 to allow space for thetrack 320 to be positioned running alongside theinboard side 19 of thecab 16 and allowing thetrack 320 to be positioned closer to a center line of thevehicle 20. Positioning thecab 16 so that thetrack 320 can run along beside theinboard side 19 of thecab 16 also allows theproximal end 32 of theboom 30 to be moved rearward behind thefront end 15 of thecab 16 and besideinboard side 19 of thecab 16, further decreasing the overall length of therock bolting machine 10 when it is in a transport position. - The
track 320 can be positioned on thevehicle 20 so that thefirst end 322 of thetrack 320 is positioned alongside of thecab 16 and behind a front of thecab 16. Thesecond end 324 of thetrack 320 can be positioned on thevehicle 20 so that when theconnection frame 302 is moved to thefirst end 324 of thetrack 320, theconnection frame 302 will be positioned over a spot between thefront wheels 14 of thevehicle 20 so that the weight of theboom 30 androck bolting apparatus 50 applied to thevehicle 20 at theproximal end 32 of theboom 30 is applied downwards between thefront wheels 14. In one aspect, theconnection frame 302 can be positioned over an axis of rotation of the pair offront wheels 14. - The movement of the
proximal end 32 of theboom 30 relative to thevehicle 20 allows therock drill machine 10 to be placed in a transport position for when therock drill machine 10 is being driven somewhere and an operating position for when therock drill machine 10 is being used to install a rock bolt in the roof of an underground space.FIGS. 6 and 7 illustrate therock bolting machine 10 in the transport position. In the transport position, theboom 30 is telescopically retracted to its most retracted and shortest length and theproximal end 32 of theboom 30 is moved to thefirst end 322 of thetrack 320. Referring toFIGS. 4 and 5 , theactuator 310 can be used to pivot theboom 30 substantially parallel to a ground surface and theboom motor 304 can be used to pivot theboom 30 so that it extends substantially straight ahead of thevehicle 20. Thepinion motor 344 can be used to rotate thepinion 342 along therack 340 until theconnection frame 302 is moved to thefirst end 322 of thetrack 320. - Referring again to
FIGS. 6 and 7 , with theboom 30 placed in the transport position, theproximal end 32 of theboom 30 is placed alongside thecab 16 and behind thefront end 15 of thecab 16 while theboom 30 is telescopically retracted to its shortest length. This can cause therock bolting machine 10 to be much more maneuverable by reducing the overall length of therock bolting machine 10 while in this transport position. -
FIG. 8 shows therock bolting machine 10 in the operating position and being used to install a rock bolt. Theproximal end 32 of theboom 30 can be moved so that it is positioned at thesecond end 324 of thetrack 320 with theproximal end 32 of theboom 30 and theconnection frame 302 positioned over thefront wheels 14. In the operating position, theboom 30 can be telescopically extended to its desired length and theboom 30 pivoted upwards if required to reach a roof of the underground space. -
FIG. 9 shows a top view of therock bolting machine 10 with theboom 30 in an operating position. Theboom 30 is telescopically extended and theproximal end 32 of theboom 30 and theconnection frame 302 are moved to thesecond end 324 of thetrack 320. In addition to theboom 30 being pivotal upwards and downwards around theproximal end 32 theboom 30 can be pivoted from side to side. - The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous changes and modifications will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all such suitable changes or modifications in structure or operation which may be resorted to are intended to fall within the scope of the claimed invention.
