Abstract
The utility model discloses a shaft drill bit guider with a planetary roller structure, which is characterized in that the shaft drill bit guider is cylindrical and is provided with a guider body, various radial adjusting arms are uniformly arranged at the periphery of the guider body, planetary roller supports are disposed at outer ends of the radial adjusting arms, planetary rollers are mounted on the planetary roller supports, and the adjacent planetary roller supports are connected via arc-shaped connecting rods. The service life of the guider can be prolonged, manufacturing cost and using cost of the guider are reduced, and guider replacing time is saved.
Description
Technical field
The utility model relates to a kind of guider, the bit guide planetary roller structure of using on a kind of shaft drilling machine of more specifically saying so.
Background technology
Using guider on the shaft drilling machine drill bit is can down creep into along existing boring at work for drill bit, set upright under the acting in conjunction of drill bit at decompression drilling process and guider, make boring can satisfy the requirement of verticality, if it is extremely unstable in rotation that the guider inefficacy will make drill bit lose direction, drill bit in creeping into, and the driving torque of rig can not normally be played a role, both waste power, can not guarantee drilling quality again.
The steel ball runway structure directing device that adopts on the existing drill bit is because the runway size is big, when increasing along with the drilling well aperture, the runway size also strengthens, and be Open architecture, runway of working in drilling mud and steel ball very easily wear and tear and are out of shape, and service life has only two to four months.Runway cost height is more changed lane and steel ball will be disassembled guider, takes more than two days, influences construction speed.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, the shaft drilling machine bit guide of the planetary roller structure of using on a kind of shaft drilling machine is provided, to improve the application life of guider, reduce guider cost and use cost, save the guider time of changing.
The utility model technical solution problem adopts following technical scheme:
The design feature of the shaft drilling machine bit guide of the utility model planetary roller structure is: be the cylindric guider parent that is provided with, periphery at described guider parent evenly is provided with each radiai adjustment arm, in the outer end of described radiai adjustment arm the planetary roller bearing is set, planetary roller is installed on the described planetary roller bearing, between adjacent planetary roller bearing, be connected with curved rod.
The transition circle is set between described regulating arm and roller carriage.
Described planetary roller is with bearing supporting on described roller carriage, in the end of described bearing dull and stereotyped sealing mat is set, and between the housing of bearing and roller carriage sealing ring is set.
When the drill bit rotary drilling, planetary roller and guider parent are together along with drill bit rotates; When planetary roller is run into well group, form rotation with respect to drill bit, to play the effect of setting upright drill bit, the slip in the time of will scraping well group simultaneously changes rolling into, has reduced the loss of drill bit driving torque.
Compared with prior art, the utility model beneficial effect is embodied in:
1, the utility model is easy to change after planetary roller damages, and guider is not disintegrated greatly.
2, the utility model planetary roller adopt bearing supporting, dull and stereotyped sealing and and install sealing ring additional, rotary part and drilling mud are kept apart, more stable and wear-resisting when guider is worked, long service life, use cost are low.
3, the guider of the utility model planetary roller structure, because of bearing is a standard component, and size is little, and than the guider handling ease of steel ball runway structure, cost is relatively low.
4, the utility model need not to make bigger guider, and the length dimension that transition circle and change regulating arm are set by increase can reach the purpose that increases the guider diameter, increases planetary roller quantity, saves the cost input, and is easy for installation.

Number in the figure: 1 guider parent, 2 radiai adjustment arms, 3 planetary roller bearings, 4 planetary rollers, 5 curved rods, 6 bearings, 7 dull and stereotyped sealing mats, 8 sealing rings, 9 transition circles, 10 drill bits, 11 central tubes, 12 steel ball runways.
The specific embodiment
Referring to Fig. 2, Fig. 3 and Fig. 4, in the present embodiment, be the cylindric guider parent 1 that is provided with, periphery at the guider parent evenly is provided with each radiai adjustment arm 2, in the outer end of radiai adjustment arm planetary roller bearing 3 is set, planetary roller 4 is installed on the planetary roller bearing 3, between adjacent planetary roller bearing 3, is connected with curved rod 5.
As shown in Figure 4, in the present embodiment, planetary roller 4 is to support in the lower end with standard rolling bearing 6 on roller carriage 3, to improve the stationarity of rotating; Dull and stereotyped sealing mat 7 is set in the end of bearing 6, between the housing of bearing 6 and roller carriage 13, sealing ring 8 is set, rotary part and drilling mud are kept apart, intercept entering of mud, increase the service life; The upper end of planetary roller 4 is to be connected on the planetary roller bearing 3 by bolt, and it is very convenient that this form is installed.
Referring to Fig. 5 and Fig. 6, in the present embodiment, between regulating arm 2 and roller carriage 3, transition circle 9 is set, when the large diameter guider of needs, only need the radiai adjustment arm of processing respective length, and the purpose that large diameter transition circle can reach increase guider diameter, increase planetary roller quantity is set.
The guider of two kinds of structures has been shown among Fig. 1, and the upper strata is the present embodiment structure, is the planetary roller structure directing device that is provided with on the central tube 11 of drill bit 10, and its periphery is a planetary roller 4; Lower floor is depicted as the steel ball runway guider of existing structure, is on the central tube 11 of drill bit 10 steel ball runway 12 to be set.
In concrete the enforcement, can as described in Figure double-deck guider or individual layer guider be set according to the needs of drill bit structure.When the drill bit rotary drilling, planetary roller and guider parent together rotate along with drill bit, when planetary roller is run into well group, form the rotation of planetary roller with respect to drill bit, like this, both played the effect of setting upright drill bit, the slip in the time of will scraping well group again changes rolling into.
When finding the planetary roller serious wear, during not working, only need to change planetary roller.
