The purpose of this utility model is in order to solve buffering and relocation mechanism not to be set in the existing rig power spindle mechanism, drilling rod can be impacted in the process of unloading, can not get buffering, damage drilling rod and main shaft easily, thereby a kind of drill power head that has buffer gear is provided.
For achieving the above object, the utility model can adopt following technical scheme:
A kind of drill power head that has buffer gear, it is to be made of unit head body, hydraulic motor, main shaft.Between the bottom end cover of unit head body and bearing (ball) cover, be provided with the main shaft buffer gear; Between main shaft buffer gear and main shaft, be provided with the liquid relocation mechanism.
The main shaft buffer gear is to be set with spring on main shaft, and spring one end and spring base are fixedly connected, and the other end contacts with bearing (ball) cover and is connected, and main shaft is a hollow body, an end opening; Spring base and left end cap are fixedly connected, and main shaft is by the spline cooperation that is connected with inner spline housing, and trapezoidal screw in compression pressing plate is fixedlyed connected with main shaft, and guide blot is fixedlyed connected formation with the unit head body; The liquid relocation mechanism be on main shaft, be provided with into the water body and with alignment of shafts intracavity inter-connection, the liquid relocation mechanism is to be contacted with bearing (ball) cover by the radial ball bearing upper end to be connected, the lower end contacts with the water inlet body and is connected, water inlet body and bearing (ball) cover are fixedly connected, end cover and water inlet body are fixedly connected, spacer, V-type folder fabric sleeve is contained on the main shaft, and and the body of intaking contact and be connected, straight joint is fixed on on the water body; Unit head body upper end is fixedly connected with the hydraulic motor base, hydraulic motor base lower end is ended button and is contacted with taper roll bearing and be connected, the other end of taper roll bearing contacts with inner spline housing and is connected, the lower end of inner spline housing contacts with another taper roll bearing and is connected, the taper roll bearing lower end contacts with bottom end cover and is connected, and bottom end cover and unit head body lower end are connected to a fixed.
The utility model has the advantages that: the main shaft of drill power head is provided with buffer gear and relocation mechanism, compare with existing mainshaft mechanism, its design concept novelty, delicate structure, be used for wherein spring principle is ingenious, make drilling rod in the unloading process, obtain good cushioning effect, prolonged the application life of drilling rod and main shaft.
Four, description of drawings
Accompanying drawing is a kind of embodiment structural representation of the utility model.
Five, the specific embodiment:
Now with instantiation the utility model is described in further details in conjunction with the accompanying drawings:
A kind of drill power head that has buffer gear, in normal drilling process, unit head can move downward along with feeding oil cylinder, because manual operation can not accurately navigate to the drilling rod place and just stop, like this when moving to drilling rod head place, can an impact be arranged to drilling rod, after main shaft 13 is impacted, can upwards axially move, owing between unit head body 2 and main shaft 13, be provided with spring 7 along inner spline housing 3, spring 7 plays cushioning effect here, spring 7 contractions that be under pressure this moment, and accordingly to a rightabout reaction force, thereby main shaft 13 upward speed slowed down, after reaction force was greater than impact force, main shaft 13 will move downward.In the process of above-mentioned motion, axial orientation motion for main shaft 13, promptly only move up and down, prevent the rotation of floating part, an auxiliary guide blot 20 is installed herein, guide blot 20 is installed in by screw thread on the bottom end cover 5 of unit head body 2, the slip of guide blot 20 auxiliary spindles 13.In order to prevent that impurity such as mud from entering in the inner spline housing 3, at an end of main shaft 13 one zero RunddichtringO 21 is installed, sealing ring 21 closely contacts with spring base 6 inner chambers, stops impurity to enter.Be set with bushing cover 15 on the unit head body 2, bushing is overlapped 15 lower surfaces and is contacted with inner spline housing 3 and be connected, and hydraulic motor 14 leans on flat key and bushing to overlap 15 internal chamber walls and contacts and be connected.Bushing is overlapped 15 outer chamber wall and is contacted with inner spline housing 3 and be connected by flat key.Unit head body 2 upper ends and hydraulic motor base 1 are fixedly connected, and are pressed with adjusting pad 16 between them.
Spring base 6 leans on screw with the bottom end cover 5 of unit head body 2, spring 7 embeds in the spring base 6, the other end of spring 7 and bearing (ball) cover 8 are close to, spline one end of main shaft 13 inserts in the inner spline housing 3, main shaft 13 usefulness pressing plates 4 and trapezoidal screw 18 are fixed in the inner spline housing 3, like this main shaft can be in internal spline the slip of easy on and off, in the process of sliding, can be subjected to the power that spring 7 is given, when spring 7 is under pressure just according to the principle of power, can give rightabout active force of main shaft, main shaft 13 is done axial directed movement up and down under the guiding of guide blot 20 and inner spline housing 3.
The liquid relocation mechanism is to be provided with into water body 11 outside main shaft 13, and water inlet body 11 is provided with straight joint 10 and is connected with the inner chamber body at main shaft 13 centers, makes liquid pass through main shaft 13 and outwards sprays.
