Description
Technical field
The utility model relates to a kind of drive unit of tunnel piercing cutterhead, particularly a kind of multi-functional.Comprise multiple fluid injection, forced feed lubrication, bending moment bite disk drive unit device.
Background technology
At present along with fast development of national economy, tunnel construction in the urban construction obtains great development, present tunnel construction generally adopts tunnel machine at mine working, its cardinal principle is that the cutterhead by the tunnel piercing chain-drive section cuts underground mud layer, and cutterhead is realized rotary cutting by the drive unit of back, because underground mud layer constitutes more complicated, therefore sometimes when cutterhead cuts mud layer, may need that mud layer is carried out slip casting and improve soil property, so that mud layer is more suitable for the machining condition in cutterhead, this just need have the slip casting unit on the drive unit at the rear portion of cutterhead.Existing cutterhead driving device is simple in structure, and the homogenous material Grouting Pipe is generally only arranged, and can't satisfy the demand for the multiple slip casting of bad ground.And cutterhead has the silt pulp-water of pressure in a large number in working angles, can enter in the development machine along the slit of cutterhead rotating shaft and development machine housing, therefore just need a wiper seal on the cutter plate driver cell arrangement, to prevent that cement mortar from refluxing, existing only cement mortar sealing device can produce the backflow phenomenon of cement mortar along with the rotatory sealing wearing and tearing.
Summary of the invention
The purpose of this utility model is to solve development machine of the prior art can't satisfy multiple slip casting and end the problem that cement mortar refluxes, and a kind of multi-functional multiple fluid injection, forced feed lubrication bending moment bite disk drive unit device are provided.The utility model design multi-functional bite disk drive unit device, comprise frame, motor, cutterhead, rotating shaft, it is characterized in that: at least two Grouting Pipe are axially arranged in rotating shaft, the front opening of Grouting Pipe is positioned on the cutterhead, the rear end of Grouting Pipe connects the multichannel swivel coupling, there is multiple-sealed groove at the place at the nearly cutterhead of rotating shaft, and macromolecule resin rotatory sealing is arranged in seal groove, connects pressure greasing oil pipe between rotatory sealing.Rotating shaft is by the motor-driven more than two groups, and motor connects rotating shaft by planetary reduction gear.Be connected by main reducing gear between rotating shaft and the planetary reduction gear.Main reducing gear is that the output pinion of gear wheel in the rotating shaft and planetary reduction gear constitutes, and described motor is a variable-frequency motor.The utility model has the advantages that slip casting when can finish multiple different slurry, and can guarantee the lubricated of transmission main shaft and prevent that outside cement mortar from refluxing, realize that simultaneously speed change regulates, change the rotation torque of cutterhead.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
The specific embodiment
Comprise frame 1, motor 2, cutterhead 3, rotating shaft 4 among the figure, it is characterized in that: at least two Grouting Pipe 5 are axially arranged in rotating shaft 4, the front opening of Grouting Pipe 5 is positioned on the cutterhead 3, the rear end of Grouting Pipe 5 connects multichannel swivel coupling 6, there is multiple-sealed groove 7 at 3 places at rotating shaft 4 nearly cutterheads, macromolecule resin rotatory sealing 8 is arranged in seal groove 7, and rotatory sealing 8 connects pressure greasing oil pipe 9.Rotating shaft 4 is driven by the motor more than two groups 2, and motor 2 connects rotating shaft 4 by planetary reduction gear 10.Be connected by main reducing gear 11 between rotating shaft 4 and the planetary reduction gear 10.Main reducing gear 11 is that the output pinion of gear wheel on the transmission main shaft and planetary reduction gear constitutes, and described motor 2 is a variable-frequency motor.
During use, drive unit is installed on the development machine, can advance tunnel piercing after connecting cutterhead 3, when the mud layer of driving needs slip casting for some reason (as muddy water, foam, chemical sizwe etc.), can slurry be injected respectively from multichannel swivel coupling 6 by pump, different subsequently slurries enters cutterhead 3 from pipeline separately, and is injected into the driving soil body, so that improve cutting and the environment and the condition of cutterhead 3 from the front opening of Grouting Pipe 5.And the macromolecule resin rotatory sealing 8 place's injection pressure lubricating grease in the seal groove 7 on the countershaft 4; can protect the frictional dissipation between rotating shaft 4 and the rotatory sealing 8; in case in the time of can guaranteeing that rotatory sealing 8 damages simultaneously, still have the lubricating grease of pressure in seal groove 7, to resist in the cement mortar water intrusion machine at cutterhead 3 places outside the development machine.In order to satisfy different drivings and to be fit to different mud layers, can utilize variable-frequency motor 2 to reach the rotation torque that changes rotating shaft 4, improve the efficient of driving, enlarged diameter when the bigger or cutterhead in the cross section of driving, can change the motor 2 on the drive unit, the configuration group number of planetary reduction gear 10, to adapt to the driving requirement in cross section, different tunnel.
