Abstract
The utility model relates to a slip fast-replacing structure for a chuck of a drilling machine, wherein a sleeve and a chute seat are disposed outside the middle section of a main shaft; the sleeve is sleeved outside the chute seat; a slip is disposed in the chute seat; a disc spring is disposed between the chute seat and the sleeve, and the top end of the disc spring is abutted against the sleeve; a lock nut is screwed on the outer wall of the upper section of the main shaft, and the lock nut is abutted against the sleeve; a top sleeve is disposed on the inner wall of the upper section of the main shaft, and the shoulder part of the top sleeve is erected on the top end surface of the main shaft; the shoulder part of the top sleeve and the lock nut, as well as the shoulder part of the top sleeve and the top end of the main shaft are fastened by locking bolts; and a replacing window is disposed on the main shaft provided with the position of the slip. The slip fast-replacing structure for a chuck of a drilling machine disclosed by the utility model can replace the slip and adjust a gripping force conveniently and fast, and can have a high reliability, so that the drilling machine is steady in operation and long in service life during a working process.
Description
Technical field
The utility model relates to a kind of slips structure that in the chuck parts of geological drilling or geotechnical engineering rig, is used for clamping drilling rod body, especially a kind of quick change slips structure of chuck of rig.
Background technology
At present, two kinds of structural shapes below widely used chuck of rig mainly contains:
First kind of chuck (see figure 2): the characteristics of this structure are that the window of 16 main shaft upper slipses 13 is open types, above gland 14 usefulness bolts 15 fixing, only need roll over when changing slips 13 except that gland 14 and can directly take out slips 13, convenient simple and direct.But because jagged on the main shaft 16, so bolt 15 is at the circumference limited amount, so very high to bolt 15 requirement of strength; Fruit main shaft 16 axial forces have impact acceleration for another example; Bolt 15 pretightning force disunities can cause bolt 15 phenomenon of ruptures often to take place, and are prone to have an accident.
Second kind of chuck (see figure 3): the characteristics of this structure are that the window of main shaft 23 upper slipses 25 is closed, and main shaft 23 is that the whole bolt that do not have limits, and axial force is carried locknut on 24 whole screw thread, so safe and reliable.But when changing slips 25, need be with locknut 24, sleeve 22, dish spring 21, skewed slot seat 26 complete removals, trouble is bothersome, is not suitable for the job site operation.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, provides a kind of and can satisfy the convenient changing slips, regulates chucking power, can have again high reliability, running steadily, the quick change slips structure of the chuck of rig of long service life.
According to the technical scheme that the utility model provides, the quick change slips structure of said chuck of rig comprises main shaft, slips, sleeve, skewed slot seat and dish spring; Be provided with sleeve and skewed slot seat in the outside, stage casing of main shaft, jacket casing is outside at the skewed slot seat, in the skewed slot seat, is provided with slips; Between skewed slot seat and sleeve, be provided with the dish spring; The top and the sleeve of dish spring offset, and are bolted with locknut at the epimere outer wall of main shaft, and locknut and sleeve offset; Epimere inwall at main shaft is provided with the top cover, and the shoulder frame that pushes up cover is on the top end face of main shaft, and is fastening through lock bolt between the shoulder that between the shoulder of top cover and the locknut and top is overlapped and the top of main shaft; On the main shaft that is provided with the slips position, offer the replacing window.
The utility model both can the convenient changing slips, regulate chucking power, can have high reliability again, made rig in the course of the work, running steadily, long service life.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
Fig. 2 is first kind of chuck structure sketch map of prior art.
Fig. 3 is second kind of chuck structure sketch map of prior art.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure: the quick change slips structure of this chuck of rig, comprise main shaft 1, slips 4, sleeve 5, skewed slot seat 6 and dish spring 7, be provided with sleeve 5 and skewed slot seat 6 in the outside, stage casing of main shaft 1; Sleeve 5 is enclosed within skewed slot seat 6 outsides; In skewed slot seat 6, be provided with slips 4, between skewed slot seat 6 and sleeve 5, be provided with dish spring 7, the top of dish spring 7 and sleeve 5 offset; Epimere outer wall at main shaft 1 is bolted with locknut 3, and locknut 3 offsets with sleeve 5; Be provided with top cover 2 at the epimere inwall of main shaft 1, the shoulder frame of top cover 2 is on the top end face of main shaft 1, between the shoulder of top cover 2 and the locknut 3 and to pass through lock bolt 8 between the top of the shoulder of top cover 2 and main shaft 1 fastening; On the main shaft 1 that is provided with slips 4 positions, offer and change window 9.
In the utility model, the clamping drilling rod body under 7 effects of dish spring of the slips 4 in the top cover 2 restriction skewed slot seats 6 guarantees the operate as normal of rig with main shaft 1 revolution.When wearing and tearing appear in slips 4, through being regulated, locknut 3 can reach the effect that improves the chuck chucking power, and easy to adjust simple and direct.When needs are changed slips 4, will push up cover 2 and remove from main shaft 1 folding, utilize the replacing window of reserving on the main shaft 19, can in main shaft 1, take out slips 4 rapidly, and the new slips of packing into, reach quick-replaceable effect.Top cover 2 connects with main shaft 1 and locknut 3 respectively through lock bolt 8, so locknut 3 has also been played locking effect.
