Description
[technical field]
The present invention relates to Dual-motors Driving stake machine braking technique field, a kind of motor inversion type two-way output stake machine deceleration device.
[background technology]
(1) Chinese Sunward Intelligent Equipment Co., Ltd. patent of invention " separable driving type sleeve screw drilling rig and construction method thereof " (ZL 200610138353.3) discloses following deceleration technical characteristic:
In the unit head C and outside unit head D of (a) inner side: the former high-end, the latter in below, two unit head separators;
B the drive unit in the unit head of () medial and lateral all adopts bi-motor secondary NGW planetary reduction gear, output pinion drives gear work done structure broad in the middle simultaneously.It mainly has problems:
(1) because the gear wheel of outside unit head D connects with major diameter (SWSD3618 type bore diameter is 1.5 meters) sleeve pipe, thus overall dimensions are incited somebody to action very greatly, heavy, cost is high and installation difficulty is large;
(2) due to the casing upper/lower terminal extra large size bearing supporting major diameter sleeve pipe of outside unit head D, not only bearing lubrication easy oil leakage and high and installation, maintenance difficulty is large by manufacturing cost out of order.
(2) the forward and reverse output of double-drive coaxial is threaded into rock drilling machine (201310615531.7)
(3) the forward and reverse speedup of double-drive coaxial exports and is threaded into rock drilling machine (201310612107.7)
(4) coaxial two positive and negative two-way output of slowing down is threaded into rock drilling machine (201310612288.3)
(5) dual output double steering enters rock unit head reductor (201410335368.3)
The problem of background technology (two) ~ (five) is: overhead bi-motor makes a machine center of gravity high, and tilting moment is large, and stake machine exists unstable hidden danger, the accident that stake chance is tumbled.This is because:
Stake machine 23 meters of screw pile driver columns allow angles of inclination to only have 3 °, and operating state ground allows ruling grade to only have 2 °, and ground, building site earth can pine, ground can not be very flat, therefore, stake machine overthrow accident does not occur unavoidably:
(1) outside Dongzhimen, 2006-04-26 Beijing, in building site, road one, Xianghe garden, a piling machine collapses suddenly, and accident causes two workman's death.Piling machine is just in operation, and the drill bit of being driven underground suddenly has stopped, and along with a sound loud noise, the arm of piling machine has just fallen, and piling machine also collapses thereupon, just in time pounds below with it two workmans.Field Force claims: " estimation is that the soil below piling machine is too loose, and ground is also uneven, so piling machine just can collapse.”
(2) 2006 years 09 month 07 day, mansion, YiShan Road,ShangHai No. 2010 Hechuans is in front of the door on building site, a piling machine is tumbled suddenly, not only press the factory building in roadside that collapsed, more result in a uncle injured, why piling machine can tumble suddenly, and mainly too pine, piling machine crank cause soil property;
(3) 2013-03-07, there is security incident together building in building site in Baoxing crossing, the Near East, high official position road, Zhabei District, Shanghai one, a piling machine topples suddenly when constructing, the shaft steel frames of more than ten meter high immediately very unexpectedly, a hit wall every an one-storey house, cause three rooms room impaired, fortunately cause no casualties.
Also there is following problems in the overhead bi-motor of background technology (two) ~ (five):
(1) owing to building building site operating mode badly, operator scarcely possesses maintenance of equipment and technical ability, and when a failure occurs, heavy motor and decelerator are difficult to tear open, and thus keep in repair, maintain difficulty;
(2) owing to building building site operating mode badly, the block of motor is difficult to waterproof and dustproof.
[summary of the invention]
The object of the invention is to provide lower than background technology cost and installation difficulty is little, easy to maintenance, a kind of motor inversion type of service-strong two-way output stake machine deceleration device.
[technical scheme]
The fewer differential teeth planetary planetary reduction gear that two motors axle stretch end connects;
Two motors inversion type is connected to below casing, and fewer differential teeth planetary planetary reduction gear is placed in casing, and motor is about output center bilateral symmetry;
Gear driving member is the driving member of two groups of dead axle flow dividing structures, comprise external toothing reduction and internal messing quasi-planet speedup part, external toothing reduction comprises the external gear of driving wheel, monosymmetric shunting gear and center gear ring, internal messing quasi-planet speedup part comprises ring gear, 3 ~ 5 there won't be any problem star-wheel and the central gears of center gear ring, the axle of shunting gear and there won't be any problem star-wheel is all fixing on the supporting plate, supporting bracket connects on the cover board, wherein:
Center gear ring connects outer sleeve, and outer sleeve relies on first and second bearing to be bearing in cover plate central circular hole, the large sleeve pipe of outer sleeve Flange joint;
Central gear connects inner core, and inner core relies on third and fourth bearing to be bearing in outer sleeve endoporus, and inner core connects auger stem.
[beneficial effect]
The background technology of ratio, its beneficial effect is:
(1) double motor inversion type structure makes heavy motor and decelerator readily removable, thus maintenance, easy maintenance;
(2) reduce the tilting moment of a machine, thus reduce overthrow accident probability;
(2) double motor inversion type structure is beneficial to motor waterproof and dustproof;
(3) pile foundation quality is high, guarantees the requirement of pile foundation high-bearing capacity, and pile foundation there will not be the problems such as pore-forming inwall subsides.
