Description
Technical field
The utility model relates to a kind of hydraulic power head, particularly relates to a kind of hydraulic power head that many grades of rotating speeds and moment of torsion are provided that is used for long-spiral drilling machine.
Background technology
Long-spiral drilling machine is a kind of pore-forming Work machine that is used for castinplace pile, and its groundwork principle is unit head drive long screw drill rod rotation and realizes creeping under the effect of drilling tool deadweight.The size of its pore-forming aperture and drilling depth depends primarily on the size of the output torque of unit head, and unit head is the critical component of long-spiral drilling machine.The unit head of China's long-spiral drilling machine all adopts two alternating current generators to drive three-ring gear reducer and drives the drilling rod rotation at present, the output shaft rotating speed can not be regulated, output torque improves difficulty, the raising of moment of torsion can only be by increasing the power of speed reducing ratio or increase motor, this makes unit head must become very huge and heavy, to the stability generation ill effect of rig.And because the electric motor starting torque is low, be difficult to restart after stopping unusually to bore, be difficult to realize automatic control again, this has limited the type rig to high pulling torque, intelligent direction development.
The utility model content
It is power with the hydraulic transmission that technical problem to be solved in the utility model provides a kind of, can export high pulling torque, compact conformation, be convenient to realize automatic control, energy creeps into for many grades, and all can be according to geological conditions at each gear, the automatic long-spiral drilling machine hydraulic power head that changes moment of torsion and rotating speed in this grade velocity interval.
In order to solve the problems of the technologies described above, the long-spiral drilling machine hydraulic power head that the utility model provides, comprise block, case lid and be installed on hollow shaft on the block, be installed on the hollow shaft and be in gear wheel in the block, the flange that is used to connect drilling rod that connects with hollow shaft, it is characterized in that: one group of hydraulic transmission is installed on the bearing of described case lid at least, and the output shaft of described hydraulic transmission is connected with gear shaft, described gear shaft and described gear wheel engaged transmission.
Described hydraulic transmission be two groups or four groups and with described hollow shaft for being symmetrically distributed on the described case lid.
Adopt the long-spiral drilling machine hydraulic power head of technique scheme, hydraulic transmission drives the hollow shaft that connects with gear wheel, is fixed with flange under the hollow shaft, is driven the drilling rod rotation that connects with flange by the hollow shaft transferring power.When gear wheel provides driving force by four hydraulic transmissions, can realize respectively that by hydraulic control valve two or four hydraulic transmissions work simultaneously.Thereby can export the moment of torsion and the rotating speed of two gears, realize the reasonable coupling of low-speed big and the little moment of torsion of high speed, improve the operating efficiency of machine greatly.And each gear is in its moment of torsion and velocity interval, and hydraulic transmission can change its discharge capacity and pressure automatically according to geological conditions equally, carries out the step-less adjustment of moment of torsion and rotating speed.When gear wheel provides driving force by four hydraulic transmissions, through four gear shaft inputs, be easy to use the mesolow hydraulic system to realize high pulling torque respectively, greatly reduce the load of bearing of the single gear teeth of gear under the equal moment of torsion, improve the reliability and the application life of system element, reduced cost.Unit head replaces original drive of motor by hydraulic drive, can reduce the weight of unit head significantly, makes its compact conformation, and has increased particularly starting torque of its output torque greatly.
Block and case lid are welded construction, seal with saturating lid and one group of sealing ring between hollow shaft output and the block, support with bearing the gear shaft lower end, bearing supports with stifle, stifle seals on block and with fluid sealant with Bolt Connection, case lid and block form a closed chamber with Bolt Connection and with the fluid sealant sealing in the middle of the whole box body, be used to store lubricated machinery oil.This body structure profile is simply compact, good manufacturability.
In sum, the utility model be a kind of be power with the hydraulic transmission, can export high pulling torque, compact conformation, be convenient to realize automatic control, energy creeps into for many grades, and all can change the long-spiral drilling machine hydraulic power head of moment of torsion and rotating speed automatically in this grade velocity interval according to geological conditions at each gear.
