Description
Technical field
The utility model relates to a kind of tunnel piercing drill bit of drilling machine, especially a kind of
two-rail gradually opens spiral form tunnel boring machine drill bit.
Background technology
In the engineering that tunnel excavation and rock stratum are exploited, rig is absolutely necessary and a kind of bores pick excavation equipment, because present stage rig specification is less, when people tunnel the boring of large aperture and ultra-large aperture, need to use the wide-aperture shield machine of driving, this driving shield machine complex structure, expensive, initial investment is huge, can considerably increase the cost of investment of engineering in engineering construction, does not also have good solution at present.
Summary of the invention
Use large aperture development machine greatly can increase engineering cost and the huge problem of initial investment to overcome present stage, the utility model provides a kind of two-rail gradually to open spiral form tunnel boring machine drill bit, this two-rail gradually opens spiral form tunnel boring machine drill bit, and not only compact conformation is simple, easily manufactured, cost is low, and its can according to bore pick operation need the boring of getting different size, therefore greatly reduce the cost of investment of engineering.
The utility model solves the technical scheme that its technical problem adopts: this two-rail gradually opens spiral form tunnel boring machine drill bit, comprising: orbit motor, passive taper gear, positive and negative silk braid, positive and negative silk threaded rod, bilateral pivoted frame track, protract cutter, rig head motor, drill, connecting line, rotating shaft, initiatively taper gear, initiatively taper gear fixed cover, this two-rail gradually opens spiral form tunnel boring machine drill bit an orbit motor, and on the rotating shaft of orbit motor, order is provided with initiatively taper gear fixed cover and active taper gear, initiatively the both sides of taper gear have been connected with a joggle passive taper gear, the front end of rotating shaft is provided with the vertical bilateral pivoted frame track of a transverse direction, passive taper gear is fixedly connected positive and negative silk threaded rod, the side of what positive and negative silk threaded rod was parallel be arranged on bilateral pivoted frame track, the rotation along with bilateral pivoted frame track drives passive taper gear around active tapering pinion rotation and positive and negative silk threaded rod, the track of bilateral pivoted frame track is provided with a rig head motor, rig head motor is connected with rotating shaft by telescopic connecting line, the afterbody of rig head motor to be matched with positive and negative silk threaded rod by positive and negative silk braid and is connected, with fixing slide post in positive and negative silk braid, positive and negative silk thread groove in slide post and positive and negative silk threaded rod is slidably matched, when positive and negative silk threaded rod rotates clockwise, slide post moves in thread groove, if slide post is in forward thread groove, slide post drives positive and negative silk braid to move downward, when slide post moves to the bottom of positive and negative silk threaded rod, because the positive/negative thread groove on positive and negative silk threaded rod is UNICOM, slide post just can enter into the reverse thread groove of positive and negative silk threaded rod, now slide post and positive and negative silk braid can move upward along with positive and negative rotating clockwise of silk threaded rod, go round and begin again like this, rig head motor just can be moved up and down on bilateral pivoted frame track, the Matching installation foremost of rig head motor has drill, due to rig head driven by motor drill carry out moving up and down while also carry out brill pick, and bilateral pivoted frame track rotates around rotating shaft, therefore drill is not only along with bilateral pivoted frame orbit rotation, but also move up and down along bilateral pivoted frame road, in addition drill self is also bored pick and is rotated, this three kinds of movement combinations thus just achieve the driving motion work track gradually opening spiral form, the top of bilateral pivoted frame track is provided with the cutter that protracts, and the cutter that protracts is for the boring of auxiliary drill driving.
The beneficial effects of the utility model are: this two-rail gradually opens spiral form tunnel boring machine drill bit, and not only compact conformation is simple, easily manufactured, cost is low, and its can according to bore pick operation need the boring of getting different size, therefore greatly reduce the cost of investment of engineering.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural principle schematic diagram of the present utility model.
In figure, 1. orbit motor, 2. passive taper gear, 3. positive and negative silk braid, 4. positive and negative threaded rod, 5. bilateral pivoted frame track, 6. protract cutter, 7. rock stratum, 8. rig head motor, 9. drill, 10. connecting line, 11. rotating shafts, 12. active taper gears, 13. active taper gear fixed covers.
Detailed description of the invention
In FIG, this two-rail gradually opens spiral form tunnel boring machine drill bit, comprising: orbit motor 1, passive taper gear 2, positive and negative silk braid 3, positive and negative silk threaded rod 4, bilateral pivoted frame track 5, protract cutter 6, rig head motor 8, drill 9, connecting line 10, rotating shaft 11, initiatively taper gear 12, initiatively taper gear fixed cover 13, this two-rail gradually opens spiral form tunnel boring machine drill bit an orbit motor 1, and on the rotating shaft 11 of orbit motor 1, order is provided with initiatively taper gear fixed cover 13 and active taper gear 12, initiatively the both sides of taper gear 12 have been connected with a joggle passive taper gear 2, the front end of rotating shaft 11 is provided with the vertical bilateral pivoted frame track 5 of a transverse direction, passive taper gear 2 is fixedly connected positive and negative silk threaded rod 4, the side of what positive and negative silk threaded rod 4 was parallel be arranged on bilateral pivoted frame track 5, the rotation along with bilateral pivoted frame track 5 drives passive taper gear 2 to rotate and positive and negative silk threaded rod 4 around active taper gear 12, the track of bilateral pivoted frame track 5 is provided with a rig head motor 8, rig head motor 8 is connected with rotating shaft 11 by telescopic connecting line 10, the afterbody of rig head motor 8 to be matched with positive and negative silk threaded rod 4 by positive and negative silk braid 3 and is connected, with fixing slide post in positive and negative silk braid 3, positive and negative silk thread groove in slide post and positive and negative silk threaded rod 4 is slidably matched, when positive and negative silk threaded rod 4 rotates clockwise, slide post moves in thread groove, if slide post is in forward thread groove, slide post drives positive and negative silk braid to move downward, when slide post moves to the bottom of positive and negative silk threaded rod 4, because the positive/negative thread groove on positive and negative silk threaded rod 4 is UNICOM, slide post just can enter into the reverse thread groove of positive and negative silk threaded rod 4, now slide post and positive and negative silk braid 3 can move upward along with positive and negative rotating clockwise of silk threaded rod 4, go round and begin again like this, rig head motor 8 just can be moved up and down on bilateral pivoted frame track 5, the Matching installation foremost of rig head motor 8 has drill 9, due to rig head motor 8 drive drill 9 to carry out moving up and down while also carry out brill pick, and bilateral pivoted frame track 5 rotates around rotating shaft 11, therefore drill 9 is not only along with bilateral pivoted frame track 5 rotates, but also move up and down along bilateral pivoted frame road 5, in addition drill 9 self is also bored pick and is rotated, this three kinds of movement combinations thus just achieve the driving motion work track gradually opening spiral form, the top of bilateral pivoted frame track 5 is provided with the cutter 6 that protracts, and the cutter 6 that protracts tunnels boring for auxiliary drill 9.
