Description

A kind of dual output double steering enters rock unit head reductor
Technical field
The present invention relates to a kind of reductor, be specifically related to dual output double steering and enter rock unit head reductor.
Background technology
Penetrate in rock-boring pouring construction at deep hole, often occur that pore-forming inwall subsides and cause pile foundation quality problem, usually the technical scheme adopted in prior art has: 1. the form of construction work of mud off, and the construction cost of this construction method is high and easily produce environment pollution; 2. adopt sleeve pipe follow-up, the constructure scheme of retaining wall pore-forming, sleeve pipe follow-up is generally divided into again three kinds of modes: a. immersed tube mode, and namely sleeve pipe makes outer tube sink to underground under the mode of hammering, vibration or static pressure; B. shake pipe mode, sleeve pipe shake static pressure effect be lowered into underground; C. rotation mode, namely sleeve pipe rotates and is lowered into underground at static pressure or Action of Gravity Field.The rotation mode of these three kinds of sleeve pipe follow-up modes shows as outstanding in efficiency of construction, construction quality and construction environment.
Normally single driving type telescoping screw special equipment is used in the equipment of rotation mode in prior art, mainly comprise and drive unit head reductor, sleeve pipe, auger stem and spiral drilling machine composition, under driving the driving of unit head reductor, outer tube and auger stem while rotate, move downward, auger stem drilling stratum or lithosphere simultaneously, helical blade casting outside auger stem, form stake holes, in stake holes, insert reinforcing cage and concrete perfusion, basis of formation stake.Although this equipment pile technique is simple, the defect having that stake of easily collapsing, pile foundation supporting capacity are poor, unit area needs quantity stake holes the more effectively to carry.
Summary of the invention
In order to overcome, prior art king-pile easily subsides, the defect of pile foundation supporting capacity difference, the invention provides a kind of dual output double steering and enters rock unit head reductor.
For reaching above object, the technical scheme that the present invention takes is:
A kind of dual output double steering enters rock unit head reductor, comprise housing, two symmetrical vertical shape power shafts are provided with in described housing, the head corresponding planetary reducer connecting hull outside separately of described each power shaft, described each power shaft is fixedly serially connected with interior input gear and outer input gear all from top to bottom successively, an output shaft parallel with two power shafts is provided with between two power shafts in described housing, described output shaft is serially connected with interior output gear and outer output gear, described interior output gear is connected with output shaft through key, described outer output gear is supported on output shaft through bearing, interior input gear on described two power shafts is respectively hung oneself idler gear and interior output gear engaged transmission, the outer input gear on described two power shafts respectively with outer output gear engaged transmission, the output of described output shaft is fixedly connected with output flange, and the end face of described outer output gear is fixedly connected with outer tube output flange.
Further, output shaft is hollow output shaft.
Again further, described outer tube output flange coaxial sleeve is connected to outside output flange.
After taking above technical scheme, beneficial effect of the present invention is:
1, the input mode adopting Dual Drive dual input shaft simultaneously to input, first after planetary reducer slows down, turning to deceleration again by breast wheel, provides enough input torques, increase the efficiency of boring.
2, output flange connects auger stem, outer tube output flange is coaxially connected with sleeve pipe, under the driving of reductor, auger stem and sleeve pipe reversely rotate to lower feeding, the helical blade of the soil that auger stem cuts and stone oil auger stem is upwards discharged, after pore-forming, sleeve pipe stays in hole, supports hole wall, prevents stake of collapsing; This technical scheme pile quality is good, efficiency is high, stake of not collapsing, and improves the supporting capacity of pile foundation.
