Abstract
The present disclosure relates to a flight bar clamp for connecting a flight bar to at least one chain link of at least one conveyor chain of a chain conveyor used in underground mining. The flight bar clamp comprises a clamp main body extending along a clamp longitudinal axis, and at least one chain link engaging portion disposed at the clamp main body configured to engage with one chain link. The at least one chain link engaging portion of the flight bar clamp includes a sacrificial anode reception, and a sacrificial anode body disposed in the sacrificial anode reception. The sacrificial anode body may protect the flight bar clamp, the flight bar and the chains from contact corrosion.

A flight bar clamp for connecting a flight bar to at least one chain link of at least one conveyor chain of a chain conveyor used in underground mining, the flight bar clamp comprising:
- a clamp main body extending along a clamp longitudinal axis;
- at least one chain link engaging portion disposed at the clamp main body and configured to engage with one chain link of the at least one conveyor chain, the at least one chain link engaging portion of the flight bar clamp including a sacrificial anode reception, wherein the sacrificial anode reception is formed as a recess, a stepped portion, or a groove at an end section of the chain link engaging portion;
- and
- a sacrificial anode body disposed in the sacrificial anode reception, wherein the sacrificial anode reception and the sacrificial anode body are configured so that the sacrificial anode body is substantially accommodated in the sacrificial anode reception.
A flight bar for connecting to at least one chain link of at least one conveyor chain of a chain conveyor used in underground mining via a flight bar clamp, the flight bar comprising:
- a flight bar main body extending along a flight bar longitudinal axis and including at least one chain link reception recess for receiving one chain link of the conveyor chain,
- a chain link engaging portion disposed in the chain link reception recess and configured to engage with the one chain link of the at least one conveyor chain, the chain link engaging portion of the flight bar including a sacrificial anode reception, wherein the sacrificial anode reception is formed as a recess, a stepped portion, or a groove at an end section of the chain link engaging portion;
- and
- a sacrificial anode body disposed in the sacrificial anode reception, wherein the sacrificial anode reception and the sacrificial anode body are configured so that the sacrificial anode body is substantially accommodated in the sacrificial anode reception.
