Turn cutting type Mining Head 1 move ahead cutting operation is carried out to seabed cobalt bearing crust, in operation process, according to the rotation of Mining Head 1
The change for turning cutting resistance is controlled to the cutting depth of Mining Head 1;When cutting resistance maintains predetermined value constant, keep adopting
The current cutting depth of ore deposit first 1 is constant;When landform or cobalt bearing crust thickness change cause cutting resistance to increase, namely when cutting hinders
When power is more than predetermined value, control Mining Head 1 moves to reduce the cutting depth to seabed cobalt bearing crust upwards;Landform or rich cobalt knot
Thickness of the shell change is when causing cutting resistance to reduce, namely when cutting resistance is less than predetermined value, control Mining Head 1 move downward with
Increase is to the cutting depth to seabed cobalt bearing crust.
The operation principle of the hydraulic system of the present embodiment is as follows:
In Fig. 1, A represents cobalt bearing crust, and B represents basement rock.In the walking operation process of undersea mining car 100, the first commutation
The reversal valve 7 of valve 5 and second commutates in the work of right position, and hydraulic motor 2 drives Mining Head 1 to rotate, and telescopic oil cylinder 3 drives swing arm
200 drive Mining Head 1 to move up and down changes cobalt bearing crust cutting depth.In cobalt bearing crust working angles, Mining Head 1 is cut
The reaction force of resistance is cut, the reaction force is acted in swing arm 200 by Mining Head 1, make Mining Head 1 that there is motion upwards to become
Gesture.
The suffered cutting resistance before cutting depth is not up to design requirement of Mining Head 1 is smaller, and the rod chamber of telescopic oil cylinder 3 enters
Oil drives Mining Head 1 to continue to move downward, and now the operating pressure of hydraulic motor 2 is also corresponding smaller, and the valve element of pressure-control valve 9 is not opened
Open, the operating pressure of telescopic oil cylinder 3 is that the second safety overflow valve 14 sets pressure.
With the increase of cutting depth, cutting resistance increases therewith, when reaction force suffered by swing arm 200 is increased to and is stretched
When the active force of oil cylinder 3 reaches equalising torque state, Mining Head 1 is no longer moved downward, the now cutting of Mining Head 1 cobalt bearing crust depth
Reach design requirement.At the same time, the operating pressure of hydraulic motor 2 also increases to predetermined value, the oil inlet V1 pressures of pressure-control valve 9
Power opens valve element under control mouth C1 pressure auxiliary, and oil inlet V1 starts overflow, and now the operating pressure of telescopic oil cylinder 3 is by pressure
Control valve 9 determines that the valve element of the second safety overflow valve 14 is closed.
With seabed mima type microrelief and crust thickness change, cutting depth and cutting resistance of the Mining Head 1 to cobalt bearing crust
With change.When cutting depth is more than design requirement, the cutting resistance increase of Mining Head 1, the operating pressure of hydraulic motor 2 also increases
Greatly, the operating pressure is acted on the control mouth C1 of pressure-control valve 9, when further reducing valve element unlatching needed for oil inlet V1
The active force for overcoming, now oil inlet V1 pressure decline, the operating pressure of telescopic oil cylinder 3 accordingly reduces, and Mining Head 1 is in cutting resistance
The lower motion upwards of effect, cobalt bearing crust cutting depth reduces, until cutting resistance and the active force of telescopic oil cylinder 3 reach torque again
Poised state;When cutting depth is less than design requirement, the cutting resistance of Mining Head 1 reduces, and the operating pressure of hydraulic motor 2 also subtracts
Small, accordingly, the control mouth C1 pressure of pressure-control valve 9 reduces, the oil inlet V1 pressure increase of pressure-control valve 9, and stretch oil
The operating pressure of cylinder 3 also increases therewith, and the active force of telescopic oil cylinder 3 drives Mining Head 1 to move downward, and cobalt bearing crust cutting depth increases
Greatly, until cutting resistance and the active force of telescopic oil cylinder 3 reach equalising torque state again.
The hydraulic system is controlled according to cutting resistance change to cutting depth, without detecting devices to landform and rich cobalt
Crust thickness is detected that the mima type microrelief change that can effectively adapt in the cobalt bearing crust recovery process of seabed becomes with cobalt bearing crust thickness
Change, can not only reduce equipment and control cost, and it is simple and reliable, it is easy to implement.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment.To those of ordinary skill in the art, the gained under the premise of the utility model technology design is not departed from
To modifications and variations also should be regarded as protection domain of the present utility model.
