Description
Technical field
This utility model relates to drilling construction mechanical field, particularly relates to a kind of raise boring machine and drives the power of rod boring
Head drive system.
Background technology
Raise boring machine is applicable to the field excavation ventilation shafts such as mine, tunnel, water conservancy and hydropower, ore pass, cage transport well etc.
Become the engineering of well enlarged diameter, during work, have the operating mode that upper and lower two working faces and well to be hoped for success are relatively large in diameter, raise boring machine
Main frame is fixed in work space.One-tenth well operation is: first bore downwards less guiding with less drilling tool from upper work surface
Hole to lower work surface, is then pulled back up counterboring with bigger drilling tool from lower work surface and goes out after the supreme work surface of bigger wellhole i.e.
Complete into well construction.Construction environment space requirement according to raise boring machine and working procedure feature, it is desirable to raise boring machine should
There is less overall dimensions to reduce the construction volume that environment space requires, require that the unit head driving rod boring drives simultaneously
System should have low-speed big and the function of the little moment of torsion of high speed, to adapt to different drilling process and then to improve work efficiency.
And drive the version of the drill head system of rod boring extremely obvious on the impact of rig overall dimensions, will for this present invention
There is provided the power-driven system that a kind of compact conformation, bulk are less, drilling ability is powerful, to improve the technology of raise boring machine
Performance level.
At present, known raise boring machine power head structure form has:
1. multi-motor adds stable drive ratio Reducer, by changing the quantity driving motor, it is achieved output moment of torsion
Change with output speed；
2. liang gear change displacement motor adds the version of stable drive ratio reductor, by changing the discharge capacity of motor, it is achieved defeated
Go out the change of moment of torsion and output speed.
3. floating bushing is installed in the lower end outside unit head.
The shortcoming of prior art
1. add stable drive ratio Reducer for the first multi-motor, by changing the quantity driving motor, real
Now output moment of torsion and the change of output speed, its gear ratio is little, and volume weight is relatively big, and gear is arranged on low-speed heave-load axle
On, heavy-duty gear bears huge radial forces and causes decline rapidly service life.
2. become displacement motor for the second two gear and add the version of stable drive ratio, except the shortcoming of the first version
Outward, hydraulic motor output high pulling torque must be improved during due to raise boring machine reaming and reduce rotating speed, but during guide hole the most not
Need the biggest moment of torsion, require again higher rotating speed to improve guide hole efficiency, because gear ratio limits, it is impossible to realize high-power time
Turn transmission, it is difficult to choose the hydraulic motor matched.
3. external floating bushing makes height of main frame bigger.The reductor of this structure occupies the space ratio that complete machine is bigger
Example, causes required transport and construction space to increase.
