Abstract
A control unit for controlling machine functions of a mining machine, such as an underground mining machine, tunneling machine or bolting rig, includes a flameproof housing having at least one fluid inlet and at least one fluid outlet, and a plurality of fluid control valves respectively communicating with the at least one inlet and outlet. In particular, the fluid control valves are formed inside at least one valve monoblock, the monoblock including a plurality of distinct fluid passages.
Claims6
A control unit for controlling machine functions of a mining machine, in particular of an underground mining machine, tunneling machine or bolting rig, the control unit comprising:
- a flameproof housing having at least one fluid inlet and/or outlet;
- a plurality of fluid control valves communicating with the at least one inlet and outlet, wherein the fluid control valves are formed inside at least one valve monoblock, the at least one monoblock including a plurality of fluid passages, wherein the at least one valve monoblock is mounted inside the flameproof housing and is fully encompassed in the flameproof housing;
- and
- at least one manifold in fluid communication with the fluid inlet and/or outlet of the flameproof housing, the at least one manifold being releasably mounted externally on the control unit on the flameproof housing.
A mining machine selected from an underground mining machine, tunneling machine or bolting rig, comprising a plurality of machine functions which are controlled hydraulically by fluid circuits, wherein said machine functions are controlled with a control unit, the control unit including a flameproof housing having at least one fluid inlet and/or outlet, and a plurality of fluid control valves communicating with the at least one inlet and outlet, wherein the fluid control valves are formed inside at least one valve monoblock, the at least one valve monoblock including a plurality of fluid passages, wherein the at least one valve monoblock is mounted inside the flameproof housing and is fully encompassed in the flameproof housing.
A mining machine host control system arranged for controlling an underground mining machine, tunneling machine or bolting rig, the control system comprising:
- a control signal input unit selected from a human-machine interface and a machine control system;
- a control unit for controlling machine functions of the mining machine;
- and
- at least one controller in signal communication with the control signal input unit and the control unit, and arranged to process operating commands received from the control signal input unit into control commands for the control unit, the control unit comprising:
- a flameproof housing having at least one fluid inlet and/or outlet;
- and
- a plurality of fluid control valves communicating with the at least one inlet and outlet, wherein the fluid control valves are formed inside at least one valve monoblock, the at least one monoblock including a plurality of fluid passages, wherein the at least one valve monoblock is mounted inside the flameproof housing and is fully encompassed in the flameproof housing.
