Abstract

A drilling rig includes a base and a rotation unit for drilling a hole in a mine surface. The rotation unit is moveably coupled to the base. The drilling rig further includes a cable feed device for feeding a cable bolt into the hole created by the rotation unit. The cable feed device is moveably coupled to the base and includes a pair of wheels and a transmission. The cable bolt is received between the pair of wheels. The transmission is coupled between the rotation unit and at least one of the wheels to transmit power from the rotation unit to at least one of the wheels.

First claim

What is claimed is:

1. A drill rig comprising:
a base defining a base axis;
a rotation unit for providing rotational power, the rotation unit movably coupled to the base;
a housing detachably coupled to the base and movable relative to the base in a direction parallel to the base axis;
a first arm pivotably coupled to the housing;
a second arm pivotably coupled to the housing, the second arm and the first arm engaging one another such that pivotal movement of one of the first arm and the second arm causes pivotal movement of the other of the first arm and the second arm;
a pair of wheels supported for rotation relative to the housing, the pair of wheels including a first wheel coupled to the first arm and a second wheel coupled to the second arm, the first wheel and the second wheel being rotatable in a plane and adapted to drive a cable along a feed direction parallel to the plane, wherein pivoting movement of the first arm and second arm causes the wheels to translate in the plane; and
a transmission for transmitting power from the rotation unit to at least one of the first wheel and the second wheel.

2. The drill rig of claim 1 , wherein the transmission includes a first gear driven by the rotation unit and a second gear engaging the first gear, wherein the second gear is coupled to one of the first wheel and the second wheel and rotation of the second gear causes the one of the first wheel and the second wheel to rotate.

3. The drill rig of claim 2 , wherein the transmission includes a first pulley coupled to the second gear, a second pulley coupled to the one of the first wheel and the second wheel, and a poly v-belt wrapped around the first pulley and the second pulley.

4. The drill rig of claim 3 , wherein the transmission includes a clutch positioned between the first pulley and the one of the first wheel and the second wheel.

5. The drill rig of claim 1 , wherein the base includes at least one feed rod extending parallel to the base axis, and wherein the housing includes at least one bracket engaging the at least one feed rod.

6. The drill rig of claim 5 , wherein the base includes a pair of feed rods, and wherein the housing includes a pair of brackets, the brackets offset relative to one another along the base axis.

7. The drill rig of claim 1 , wherein moving the first arm in a first direction relative to the housing causes the first wheel to move away from the second wheel, and moving the first arm in a second direction opposite the first direction causes the first wheel to move toward the second wheel.

8. The drill rig of claim 1 , wherein the pair of wheels are configured to receive a cable between the wheels, the cable curving from a substantially horizontal direction to a substantially vertical direction.

9. The drill rig of claim 8 , wherein the pair of wheels move toward one another when the cable is pulled in a direction opposite the feed direction.

10. The drill rig of claim 1 , wherein the housing and the rotation unit move together relative to the base.

11. A drill rig comprising:
at least one rod extending parallel to a base axis;
a rotation unit for providing rotational power, the rotation unit supported for movement relative to the rod parallel to the base axis; and
a cable feed device including
a housing removably coupled to the rod and movable relative to the rod parallel to the base axis,
a first wheel supported for rotation on the housing and configured to drive a cable in a feed direction, the first wheel supported on a first arm pivotably coupled to the housing,
a second wheel spaced apart from the first wheel and supported for rotation on the housing, the second wheel configured to drive the cable in the feed direction, the second wheel supported on a second arm pivotably coupled to the housing, the second arm engaging the first arm such that pivotal movement of one of the first arm and the second arm causes pivotal movement of the other of the first arm and the second arm, and
a transmission unit detachably coupled to the rotation unit and transmitting power from the rotation unit to the first wheel,
wherein pivotal movement of the first arm and the second arm causes the first wheel and the second wheel to translate in a plane parallel to the feed direction.

12. The drill rig of claim 11 , wherein moving the first arm in a first direction relative to the housing causes the first wheel to move away from the second wheel, and moving the first arm in a second direction opposite the first direction causes the first wheel to move toward the second wheel.

13. The drill rig of claim 11 , wherein the transmission unit includes a first pulley driven by the rotation unit, a second pulley coupled to one of the first wheel and the second wheel, and a belt wrapped around the first pulley and the second pulley.

14. The drill rig of claim 11 , wherein the cable feed device includes a clutch positioned between the transmission unit and the first wheel.

15. The drill rig of claim 11 , wherein the housing includes a pair of brackets for detachably engaging the rod, wherein the brackets are offset from one another in a direction parallel to the base axis.

16. A drill rig comprising:
a pair of parallel rods oriented parallel to a base axis;
a rotation unit for providing rotational power, the rotation unit supported for movement relative to the rods along the base axis;
a housing slidable relative to the rods along the base axis, the housing including a first arm pivotably coupled to the housing and a second arm pivotably coupled to the housing, the first arm and the second arm engaging one another, the housing including a pair of brackets, each bracket detachably engaging one of the rods, the brackets offset from one another in a direction parallel to the base axis;
a first wheel supported on the first arm and rotatable relative to the housing;
a second wheel spaced apart from the first wheel and supported on the second arm, the second wheel rotatable relative to the housing;
a transmission unit including a gear drive transmitting power from the rotation unit to the first wheel.

17. The drill rig of claim 16 , wherein the first wheel and the second wheel are configured to drive the cable in a feed direction.

18. The drill rig of claim 16 , wherein pivotal movement of the first arm and the second arm causes the first wheel and the second wheel to translate in a plane parallel to the feed direction.

19. The drill rig of claim 16 , wherein the second arm engages the first arm such that pivotal movement of one of the first arm and the second arm causes pivotal movement of the other of the first arm and the second arm.

20. The drill rig of claim 19 , wherein the one of the first arm and the second arm includes a pin and the other of the first arm and the second arm includes a slot receiving the pin, the pin being slidable within the slot.
