Abstract
The utility model provides a flexible reducing joint for an engineering drilling machine and a shaft drilling machine, comprising a cross pivot shaft mechanism, a spring mechanism, a counter shaft and an outer casing. Inner cylindrical pins are matched and connected with the counter shaft through a middle bushing, two outer cylindrical pins and the middle bushing are matched and connected with the outer casing, and the outer cylindrical pins and the middle bushing are arranged on the outer casing. The two inner cylindrical pins and the two outer cylindrical pins form the cross pivot shaft mechanism. The middle bushing is arranged on the outer part of the counter shaft and wobbles around the cylindrical pin. The lower part of the counter shaft is supported on the outer casing by a spring supporting block structure, a spring base is arranged on the upper part of the outer casing and fixed on the outer casing through a screw bolt, and a spring is arranged on the spring base. The additional bending moment of the drilling system can be truncated on the flexible reducing joint, which can effectively prevent the additional bending moment from spreading upwards, thus the stress situation of the reducing joint of the drilling machine and the whole drilling system can be effectively improved, and the service life of the drilling tool can be prolonged.
Description
Technical field:
The utility model relates to engineering driller, shaft drilling machine drilling rod link technique field, the flexible reducer union of a kind of engineering driller, shaft drilling machine.
Technical background:
At present, traditional engineering driller, the reducer union of shaft drilling machine genus are rigidly connected, and it is used for the transition junction of drilling rod and lower drilling tool system; Rig is the bit force more complicated in drilling process, and operating mode is abominable, and the inhomogeneous power of suffered horizontal direction of drill bit and vertical direction produces huge additional bending moment to the top drilling system, thus the application life of having reduced drilling system; Since reducing suddenly of reducer union top and drilling rod junction radial dimension, the additional bending stress maximum that additional bending moment produces on reducer union top, reducer union is stressed the most abominable, and the life-span reduces greatly, and reducer union very easily damages.
Summary of the invention:
For overcoming the defective that exists as mentioned above, the utility model provides the flexible reducer union of a kind of engineering driller, shaft drilling machine, this joint can block additional bending moment from reducer union, thereby effectively stop additional bending moment upwards to be propagated, improve the force-bearing situation of reducer union, drilling tool and top rod.
For achieving the above object, the utility model adopts following technical scheme:
The flexible reducer union of described engineering driller, shaft drilling machine is made up of cross hinged shaft mechanism, spring mechanism, jackshaft and external shell; The cross hinged shaft mechanism is made of two inner circular pins and two outside straight pins, the inner circular pin is connected by middle ring set and jackshaft, two outside straight pins, middle ring set and external shells are connected, and outside straight pin and middle ring set are installed on the external shell; Spring mechanism is made of spring and spring base, and spring base is positioned at external shell top, and by being bolted on the external shell, spring mounts elastically, and spring mechanism can be swung around jackshaft with external shell; Middle ring set is installed in the jackshaft outside, and can swing around straight pin, and the bottom of jackshaft is by spring back-up block support structure externally on the housing.
Owing to adopted as above technical scheme, the utlity model has following superiority:
This project rig, the flexible reducer union of shaft drilling machine, be with engineering driller, the vitals rigidity reducer union of shaft drilling machine becomes flexible reducer union, be installed in the transition junction of the drilling rod and the drilling system of rig, when additional bending moment acts on flexible reducer union, middle ring set, relative motion between the straight pin makes the relative jackshaft of external shell produce the beat effect, the compression spring buffer, thereby block upwards propagating of additional bending moment, effectively improve the force-bearing situation of rig reducer union and whole drilling tool thereof, additional bending moment in the drilling system is blocked from flexible reducer union, improve the application life of drilling tool.
Description of drawings:
Fig. 1 is the flexible reducer union structural representation of engineering driller, shaft drilling machine.
Fig. 2 is the flexible reducer union vertical view of engineering driller, shaft drilling machine.
As shown in Fig. 1,2: 1-spring, 2-spring base, ring set in the middle of the 3-jackshaft, 4-, 5-external shell, 6-inner circular pin, 7-outside straight pin, 8-spring back-up block mechanism.
The specific embodiment:
As shown in Figure 1, 2: the flexible reducer union of this project rig, shaft drilling machine, mainly form by cross hinged shaft mechanism, spring mechanism, jackshaft and external shell; Inner circular pin (6) is connected by middle ring set (4) and jackshaft (3), two outside straight pins (7), middle ring set (4) and external shells (5) are connected, outside straight pin (7) and middle ring set (4) are installed on the external shell (5), middle ring set (4) is installed in jackshaft (3) outside, and can be around straight pin (6) (7) swing, two inner circular pins (6) and two outside straight pins (7) form the cross hinged shaft mechanism; The bottom of jackshaft (3) is supported on the external shell (5) by spring back-up block structure (8): spring base (2) is positioned at external shell (5) top, and by being bolted on the external shell (5), spring (1) is installed on the spring base (2), spring (1) and spring base (2) constitute spring mechanism, and spring mechanism can be swung around jackshaft with external shell (5).When additional bending moment acts on flexible reducer union, relative motion between middle ring set (4), the straight pin (6) (7) makes the relative jackshaft of external shell (3) produce the beat effect, the compression spring buffer, thereby block upwards propagating of additional bending moment, effectively improve the force-bearing situation of rig reducer union and whole drilling tool thereof.
Divide three kinds of situations to specify below:
(1), when additional bending moment when the A-A face acts on flexible reducer union, flexible reducer union external shell (5) drives two straight pins in the outside (7) and around middle ring set (4) beat takes place, compression spring (1) plays cushioning effect, the power that jackshaft (3) is subjected to only is length of spring compressed effect micro force in the above, thereby additional bending moment is blocked from here, effectively improve the drilling system force-bearing situation.
(2), when additional bending moment when the B-B face acts on flexible reducer union, beat took place around inner two straight pins (6) in ring set (4) in the middle of flexible reducer union external shell (5) drove by two straight pins in the outside (7), compression spring (1) plays cushioning effect, the power that jackshaft (3) is subjected to only is length of spring compressed effect micro force in the above, thereby additional bending moment is blocked from here, effectively improve the drilling system force-bearing situation.
(3), when any position (for example C-C face) of additional bending moment between A-A, B-B face when acting on flexible reducer union, the forms of motion of flexible reducer union is the synthetic of above two kinds of motions.Play cushioning effect as above-mentioned compression spring (1), the power that jackshaft (3) is subjected to only is length of spring compressed effect micro force in the above, thereby additional bending moment is blocked from here, effectively improves the drilling system force-bearing situation.
