Definitions

  • the present invention relates generally to a cable feeder. Specifically, a cable feeder arranged on a mining or construction machine.
  • One solution for facilitating the transition to electrical driven machines is connecting an electric cable to the machine, for example for transport, operation and for charging of on-board batteries.
  • a cable may for example be needed when battery power is not sufficient for the heavy and energy intensive operations performed by the mining machines.
  • the cable provides the machine with electricity during operation and therefore trails behind the machine in the mining environment.
  • the cable is reeled in and out by means of a cable handling system, commonly located at the back of the machine.
  • the cable handling system may be configured to position the cable on a cable reel when reeling in the cable.
  • the cable handling system may furthermore position the cable on the ground to prevent the machine from running over the cable.
  • a problem with present cable handling systems is the risk of tangling of the cable in the cable handling system.
  • the cable may be tangled on the cable reel. If the cable is tangled, an operator may be required to climb up onto the mining machine to un-tangle it, which presents a great risk to the operator as operators in the mining environment are commonly not equipped with sufficient safety equipment for such a task.
  • two operators are even required to solve the problem which, in addition to the increased risk, is highly time consuming and inefficient.
  • a hose may for example be a hydraulic hose connected to a remote hydraulic pump.
  • Hydraulic systems are vital on mining machines, for example for operating tools such as drills. Thus, tangling of such a hose leads to production stops and may be dangerous to people nearby.
  • An object of the present disclosure is to overcome at least some of the problems outlined above. This object is achieved in a first aspect of the disclosure by providing a feeder for feeding a cable or hose operatively connected to a machine for mining or construction, the cable/hose being connected remote from the machine at another end thereof.
  • the cable/hose feeder is arranged to be placed on the machine.
  • the cable/hose feeder comprises a feeding means 420, arranged to engage the cable/hose, a transmission means 430, operatively connecting a drive system to the feeding means 420, wherein the transmission means 430 comprises a one-way drive mechanism, configured to allow the feeding means 420 to be driven by the drive system in a first direction, and freewheel in a second, opposite direction.
  • the cable/hose feeder is configured to feed or pull the cable/hose in the first direction to reel out the cable/hose from the machine.
  • the cable/hose is for example reeled out when the machine is traveling forward or turning and therefore requires more cable/hose between the machine and the remote connection point of the cable/hose.
  • the cable/hose may also be reeled out for the purpose of detangling the cable/hose when it has been tangled for example on a cable/hose reel. Since the cable/hose is allowed to freewheel in the second direction, the cable/hose feeder does not create any resistance or obstacle when the cable/hose is pulled through the cable feeder in that direction. This may for example be advantageous when the cable/hose is reeled in and out by means of different parts of a system.
  • the one-way drive mechanism makes it possible to utilize the cable/hose feeder only for reeling out the cable/hose, without it presenting an obstacle when reeling in the cable/hose.
  • the feeding means comprises at least one conveyor belt.
  • the feeding means comprises a first conveyor belt and second conveyor belt arranged opposite each other, between which the cable/hose is arranged to pass.
  • the at least one conveyor belt comprises a plurality of conveyor segments being linked to form a closed loop.
  • each conveyor segment is releasably attached to the at least one conveyor belt.
  • each conveyor segment is 3D-printed.
  • 3D-printing the conveyor segments allows for changing the design of the conveyor belt, without having to exchange the entire conveyor belt. For example, improving the design to better engage the cable/hose, or adapting the design for a different cable/hose dimension.
  • the feeding means is formed by a polymer material.
  • the one-way drive mechanism operatively connects the transmission means to the feeding means.
  • the transmission means comprises a transmission shaft, and wherein the one-way drive mechanism is arranged at an end of the transmission shaft.
  • the freewheel mechanism is a one-way ball bearing.

  • the cable/hose feeding system comprises a cable/hose reel, onto which the cable/hose is arranged to be wound, a cable/hose guiding arm 320, extending from the cable/hose reel, and a cable/hose feeder according to any one of the exemplary embodiments.
  • the cable/hose feeder is arranged on the cable/hose guiding arm.
  • the cable/hose feeder is arranged to pull the cable/hose in a first direction to reel out the cable/hose from the cable/hose reel, and the cable/hose reel is arranged to rotate to pull the cable/hose in a second direction, opposite the first direction, to reel in the cable/hose on the cable/hose reel.
  • a machine for mining or construction the machine being operatively connected to a cable/hose, the cable/hose being connected remote from the machine at another end thereof, wherein the machine comprises a cable/hose feeder according to any one of the exemplary embodiments or a cable/hose feeding system according to any one of the exemplary embodiments.
