Device for removing a wear member
A device for removing a wear member from a ground engaging surface, the device comprising: a body having cavity and a wear member engaging portion to engage the wear member when the wear member extends into the cavity; a gripper movable relative to the body, the gripper having a bracing member adapted to bear against a portion of the ground engaging surface to thereby provide a load path from the ground engaging surface to the wear member engaging portion; and a first actuator connected to the gripper and the body, to apply a force to the gripper, to urge the gripper to move relative to the body, such that, when the bracing member bears against the ground engaging surface, movement of the gripper relative to the body removes the wear member from the ground engaging surface.
1. A device for removing a wear member from a ground engaging surface, the device comprising: a body having a cavity and a wear member engaging portion to engage the wear member when the wear member extends into the cavity, the wear member engaging portion being movable between an open position to allow movement of the wear member into the cavity, and an engaged position to engage a recess in the wear member when the wear member extends into the cavity; a gripper movable relative to the body, the gripper having a bracing member adapted to bear against a portion of the ground engaging surface to thereby provide a load path from the ground engaging surface to the wear member engaging portion; and a first actuator connected to the gripper and the body, to apply a force to the gripper, to urge the gripper to move relative to the body, such that, when the bracing member bears against the ground engaging surface, movement of the gripper relative to the body removes the wear member from the ground engaging surface; wherein the movement of the gripper relative to the body between a first position and a second position causes the wear member engaging portion to move between the open position and the engaged position, respectively.
2. The device according to claim 1 , wherein the device further includes a second actuator connected between the body and the first actuator to move the gripper between the first position and the second position, and the first actuator is adapted to move the gripper between the second position and a third position, thereby, if the wear member is engaged by the wear member engaging portion, removing the wear member from the ground engaging surface.
3. The device according to claim 2 , wherein the second actuator moves the first actuator to move the gripper relative to the body.
4. The device according to claim 1 , wherein the bracing member includes a spacer adapted to bear against a side of the ground engaging surface.
5. The device according to claim 3 , wherein the side is generally perpendicular to the portion of the ground engaging surface.
6. The device according to claim 1 , wherein the device is suspended from a crane, the crane being located on a utility vehicle, the utility vehicle further having a power supply;
wherein the first actuator and/or a second actuator are powered by the power supply.
7. The device according to claim 6 , wherein the power supply is a portable hydraulic power supply.
8. The device according to claim 1 , wherein the body further includes a damping member located in the cavity to receive the wear member.
9. The device according to claim 8 , wherein the damping member is a resilient member biased towards the gripper.
10. The device according to claim 9 , wherein the resilient member is biased towards the gripper by a spring between the resilient member and the body.
11. The device according to claim 10 , wherein the spring extends from the resilient member away from the wear member engaging portion towards the body.
12. A method of removing a wear member using the device of claim 1 .
