Three phase asynchronous motor is flame-proof mine, meets and has the colliery of flame proof requirement to use.
Working connection hand change over valve is in 3-position 4-way, to arrange formula hand change over valve.
When the left position of working connection hand change over valve is connected, the oil circuit that declutches is connected.When working connection manual reverse of direction valve position, left position all disconnect, when hand change over valve is positioned at meta, be middle row's formula, spool arrives midway location, and valve is in oil extraction state.When the right position of working connection hand change over valve is connected, tensioning oil circuit is connected.
The oil circuit solenoid directional control valve that declutches is flame-proof mine two-position three way list electric control electromagnetic change-over valve.
While declutching oil circuit solenoid directional control valve coil blackout, under the effect of spring, the left position of the oil circuit solenoid directional control valve that declutches is connected.The oil cylinder that declutches is drained the oil, the cylinder movement that declutches, and brake is stopped tightly.While declutching oil circuit solenoid directional control valve coil electricity, the right position of the oil circuit solenoid directional control valve that declutches is connected.The oil cylinder that declutches refuels, and promotes to declutch cylinder movement, and brake unclamps.The oil circuit solenoid directional control valve that declutches is flame-proof mine, meets and has the colliery of flame proof requirement to use.
Tensioning oil circuit change-over valve is in 3-position 4-way, to arrange formula hand change over valve.
When the right position of tensioning oil circuit hand change over valve is connected, Hydraulic Pump starts toward energy storage topping up, tensioning cylinder oil-feed, and continuous rope rope starts tensioning.When the left position of tensioning oil circuit hand change over valve, right position all disconnect, when change-over valve is positioned at meta, be middle row's formula, spool arrives midway location, and valve is in oil extraction state.When the left position of tensioning oil circuit hand change over valve is connected, discharge fluid in energy storage, tensioning cylinder is drained the oil, and continuous rope rope starts slack rope.
The beneficial effects of the utility model are: both can be wound around by brake oil cylinder control the checking or unclamp of friction roll of continuous rope, and again can be by the tensioning degree of tensioning hydro-cylinder control continuous rope.Easy to operate, safe and reliable, to be applicable to the requirement of coal mine downhole mine flame proof hydraulic power unit.
