Abstract
The utility model relates to a kind of adjusting microinching formula drilling well helicoid hydraulic motor, comprise housing and power transmission shaft, housing is socketed in power transmission shaft outside, between housing and power transmission shaft, be provided with an annular exciting assembly, exciting assembly mainly comprises the planet ratchet group that two ratchet cover plates form, by relatively rotating of two ratchet cover plates, realize moving axially of drill bit, thereby produce, impact, simple in structure, convenient disassembly.
Description
Technical field
The utility model relates to oil drilling and geologic prospect hydraulic impactor for well drilling and helicoid hydraulic motor technical field, is a kind of drilling tool with impact function specifically.
Background technology
Traditional adjusting microinching formula drilling well helicoid hydraulic motor only has a single reciprocating impact mechanism, and for the lower operating mode of rotating speed, the situation that work does not occur the low or vibrational structure of vibration force easily occurs traditional single beater mechanism.
Utility model content
The technical problems to be solved in the utility model is: overcome existing technical problem in prior art, a kind of adjusting microinching formula drilling well helicoid hydraulic motor with multi-stag reciprocating impact mechanism is provided.
The utility model solves the technical scheme that its technical problem adopts:
A kind of adjusting microinching formula drilling well helicoid hydraulic motor, comprise housing and power transmission shaft, housing is socketed in power transmission shaft outside, between housing and power transmission shaft, be provided with an annular exciting assembly, described exciting assembly comprises spring, open the seat that shakes, steel body impact sleeve and impact base, described inner walls is provided with a protruding ring, described spring one side top is pressed on protruding ring, described spring, open the seat that shakes, steel body impact sleeve and impact base are successively set on power transmission shaft, described transmission the tip of the axis is provided with alloy striker, described alloy striker is fixed on power transmission shaft, between described alloy striker and housing, be provided with bearing, described impact base top is pressed on alloy striker,
Described open shake seat comprise open shake seat and lower Qi Zhenzuo, on described, open shake seat and lower Qi Zhenzuo be circular, on described, open shake seat and under open on the opposite face of the seat that shakes and be provided with intermeshing ratchet, described upper Qi Zhenzuo is fixed on turning cylinder, opens the seat that shakes under described and endwisely slips along turning cylinder;
As further innovation of the present utility model, described bearing is TC bearing.
As further innovation of the present utility model, in the outside wall surface of described steel body impact sleeve, be processed with two annular groove B, in described groove B, annular array is inlaid with steel ball group B.
The beneficial effects of the utility model are, the utility model drives drill bit to vibrate by simple planet ratchet structure, than traditional adjusting microinching formula drilling well helicoid hydraulic motor, the utility model is simple in structure, easy to maintenance, frictional force when steel ball group A effectively reduces the rotation of planet ratchet structure simultaneously, has improved the performance of rotating, and has reduced energy consumption.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, the utility model is a kind of adjusting microinching formula drilling well helicoid hydraulic motor, comprise housing 1 and power transmission shaft, housing 1 is socketed in power transmission shaft outside, between housing 1 and power transmission shaft, be provided with an annular exciting assembly, exciting assembly comprises spring 2, open the seat that shakes, steel body impact sleeve 7 and impact base, housing 1 inwall is provided with a protruding ring, spring 2 one side tops are pressed on protruding ring, spring 2, open the seat that shakes, steel body impact sleeve 7 and impact base are successively set on power transmission shaft, transmission the tip of the axis is provided with alloy striker 9, alloy striker 9 is fixed on power transmission shaft, between alloy striker 9 and housing 1, be provided with TC bearing 10, impacting base top is pressed on alloy striker 9,
Open shake seat comprise open shake seat 3 and under open shake seat 5, on open shake seat 3 and under open shake seat 5 be circular, on open shake seat 3 and under open on seat 5 the opposite face that shakes and be provided with intermeshing ratchet, described upper Qi Zhenzuo is fixed on turning cylinder, opens the seat that shakes under described to endwisely slip along turning cylinder; Under open shake seat 5 towards on open the seat that shakes a side be provided with an annular groove A, in described groove, annular array is inlaid with steel ball group A4;
In the outside wall surface of steel body impact sleeve 7, be processed with two annular groove B, in groove B, annular array is inlaid with steel ball group B6;
In housing 1 upper end, be also provided with the connecting portion 11 of rotating machinery;
When holing, rig drives power transmission shaft by connecting portion 11, make to open shake seat and under open the seat that shakes a relative sliding occur, thereby change the contact condition of ratchet, distance between ratchet is changed, change by this distance drives steel body impact sleeve to move, thereby drill body is moved axially, and produces impact force.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to claim scope.
