21；Main winch motor connects the second hydraulic fluid port 12 and the 4th hydraulic fluid port 22, and the drilling tool of master winch can be driven to rise or decline.
Specifically, when hydraulic oil is pumped into first hydraulic fluid port 11 by oil pump, hydraulic oil passes through rising by the first hydraulic fluid port 11
Oil duct 10 flows to the second hydraulic fluid port 12, the pressure increase at the second hydraulic fluid port 12, driving main winch motor operating, so as to drive master file
The drilling tool raised rises.In the process, the hydraulic oil at the second hydraulic fluid port 12 gradually flows to the 4th hydraulic fluid port 22, and under
Drop oil duct 20 flows to the 3rd hydraulic fluid port 21, and the hydraulic oil at the 3rd hydraulic fluid port 21 can be pumped to the first hydraulic fluid port 11, shape again
Into circulation.
When hydraulic oil is pumped into three hydraulic fluid port 21 by oil pump, hydraulic oil is flowed by the 3rd hydraulic fluid port 21 by declining oil duct 20
Move to the 4th hydraulic fluid port 22, the pressure increase at the 4th hydraulic fluid port 22, main winch motor antiport is driven, so as to drive master winch
Drilling tool declines.In the process, the hydraulic oil at the 4th hydraulic fluid port 22 gradually flows to the second hydraulic fluid port 12, and by rising oil
Road 10 flows to the first hydraulic fluid port 11, and the hydraulic oil at the first hydraulic fluid port 11 can be pumped to the 3rd hydraulic fluid port 21 again, and formation follows
Ring.
The process of drilling tool raising and lowering is driven above, is required to using oil pump control running of hydraulic power oil to drive master winch
