In said program, the 5th pipeline is further included, the 5th pipeline connects second pipeline and the third pipe
Road, the 5th pipeline are equipped with overflow valve.
In said program, the 6th pipeline is further included, the 6th pipeline connects the reversal valve and the 4th pipeline,
6th pipeline is equipped with safety valve.
In said program, the feed cylinder is equipped with power head, and the power head is mechanically connected drill rod assemblies.
The utility model limits lifting force by safety valve, drilling machine can be made to reach maximum lifting force, promoted in time
Drilling rod and drill bit avoid that lock of tool drilling occurs, and by the one-way overflow valve on third pipeline, are adjusted and obtain stable promotion
Power can be set with this and obtain stable centripetal force, stable pressure is provided for drill bit, improves the service life of drill bit.
Description of the drawings
Fig. 1 is the schematic diagram of specific embodiment one in the utility model；
Fig. 2 is the schematic diagram of specific embodiment two in the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings of the specification.
As shown in Figure 1 and Figure 2, the utility model provides a kind of water drilling rig feed arrangement at a slow speed, including the first pipeline,
Second pipeline, third pipeline and the 4th pipeline.First pipeline connects fuel tank 10 and reversal valve 20, and the first pipeline is equipped with oil pump
11.Second pipeline connects the rod chamber 30 of reversal valve 20 and feed cylinder.Third pipeline connects reversal valve 20 and feed cylinder
Rodless cavity 31.4th pipeline connects reversal valve 20 and fuel tank 10.In order to advanced optimize working performance, third pipeline is equipped with single
To overflow valve 40, to maintain pipeline pressure, the second pipeline is equipped with first pressure gauge 12, and third pipeline is equipped with second pressure
Table 13, to show pressure size.
Feed arrangement further includes the 5th pipeline and the 6th pipeline to this water drilling rig at a slow speed, the 5th pipeline connect the second pipeline and
Third pipeline, the 5th pipeline are equipped with overflow valve 50.6th pipeline connects 20 and the 4th pipeline of reversal valve, and the 6th pipeline is equipped with
Safety valve 60, to maintain pressure security.
Feed cylinder is equipped with power head 70, and power head 70 is mechanically connected drill rod assemblies.Drill rod assemblies include 71 He of drilling rod
Drill bit 72, drilling rod 71 are mechanically connected with power head 70, and drill bit 72 is arranged on the end of drilling rod 71, and power head 70 passes through 71 band of drilling rod
Dynamic drill bit 72 rotates or is promoted drill bit 72.
Weight+70 weight of power head-frictional force+centripetal force-of the power being applied on drill bit 72=drilling rod 71+ drill bits 72 carries
Lift.Every time drilling when, drilling rod 71, drill bit 72 weight for determine value, 70 weight of power head be fixed value, change in friction force is not
Greatly, it can be considered definite value, the centripetal force being applied on rod chamber 30 can be set, and the lifting force being applied on rodless cavity 31 is variation
Value.
Feed arrangement has drilling and promotes two kinds of operating modes this water drilling rig at a slow speed, with reference to specific embodiment one and tool
Body embodiment two illustrates respectively；
Specific embodiment one：
Under drilling condition, it can be set as feeding at a slow speed by reversal valve 20, fluid is input to rod chamber 30 by oil pump 11
It is interior, at this point, the size of centripetal force is can adjust by overflow valve 50, since the third pipeline of connection rodless cavity 31 is equipped with unidirectional overflow
Valve 40 is flowed, lifting force, the pressure size setting of one-way overflow valve 40 are adjusted by adjusting the pressure size of one-way overflow valve 40
Kept stable afterwards.
In conclusion the centripetal force of this water drilling rig feed arrangement at a slow speed can be set, and kept substantially after lifting force setting
Stablize, provide steady pressure as drill bit 72, improve the service life of drill bit 72, further, since being applied to drill bit 72
On pressure can approximation see constant force as, in formation variation, feed speed can adjust automatically, improve construction efficiency, grasp
Make simply, not needing to operating personnel and manually adjust, reduce the requirement to operator quality.
Specific embodiment two：
When encountering lock of tool drilling, need to promote drilling rod 71 and drill bit 72, it, can be by pulling reversal valve in the case where promoting operating mode
20 change oil circuit, and drilling rod 71 and drill bit 72 are promoted, at this point, safety valve 60 limits lifting force, drilling machine can be made to reach most
Big lifting force ensures to promote drilling rod 71 and drill bit 72 in time, avoids that lock of tool drilling occurs, and ensures that construction is smoothed out.
The utility model limits lifting force by safety valve 60, drilling machine can be made to reach maximum lifting force, carried in time
Drilling rod 71 and drill bit 72 are risen, avoids that lock of tool drilling occurs, by the one-way overflow valve 40 on third pipeline, is adjusted and obtains steady
Fixed lifting force can be set with this and obtain stable centripetal force, provided stable pressure for drill bit 72, improved drill bit 72
Service life.
