Description
[technical field]
The present invention relates to Dual-motors Driving stake machine braking technique field, a kind of motor inversion type internal messing four shunts stake machine deceleration device.
[background technology]
Patent Office of the People's Republic of China successively discloses following patent:
(1) screw pile machine power head (201020300223.7)
(2) Novel high torque stake mechanomotive force head hard-tooth surface speed reducer (201210558920.6)
(3) the forward and reverse output of double-drive coaxial is threaded into rock drilling machine (201310615531.7)
(4) the forward and reverse speedup of double-drive coaxial exports and is threaded into rock drilling machine (201310612107.7)
(5) coaxial two positive and negative two-way output of slowing down is threaded into rock drilling machine (201310612288.3)
(6) dual output double steering enters rock unit head reductor (201410335368.3)
(7) screw rod pile machine is with high pulling torque power head device (201420625553.1)
The problem of background technology is: bi-motor overhead is installed, and thus stake machine center of gravity is 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 has been the upper too pine below piling machine, and ground is also uneven, so piling machine just can collapse.”
(2) 2006 years 09 month 07 mouthful, 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:
(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.
The technical characteristic of Novel high torque stake mechanomotive force head hard-tooth surface speed reducer (201210558920.6) in background technology is:
" (two) helical gear shaft engages with central gear "
The weak point of this technology is now described by example ZZSH-630 type:
Central gear Z=67, m=16.0, b=256, output torque are 194362 × 2 (Nm)
Central gear external diameter Φ 1104, owing to only there being two shuntings, makes the weight 1920kg of central gear, nearly 40,000 yuan of price.
(2) background technology just must can be picked up and looks into decelerator with weigh two motors of 820kg of loop wheel machine dismounting, as long as and the present invention backs out bolt and opens cover plate, thus keep in repair, maintain very convenient.The present invention only needs an easy truck to be placed under motor, backs out bolt and relies on motor deadweight to pull down;
(3) reduce the tilting moment of a machine, thus reduce overthrow accident probability;
(4) modified, the gear shaping technique of ring gear of the present invention needs carburizing, roll flute difficulty little than the gear wheel of background technology, and low cost of manufacture is not easy to crack;
(3) double motor inversion type structure is beneficial to motor waterproof, has stopped the accident of burning because of water inlet in motor coil.
[summary of the invention]
A kind of motor inversion type internal messing four that the object of the invention is to provide lower than background technology cost, installation difficulty is little, easy to maintenance and safe and reliable shunts stake machine deceleration device.
[technical scheme]
Two motors inversion type is connected to below casing, and arranges about output center bilateral symmetry;
Two motors axle stretch end connects Reducer With Involute Gear of Less-tooth Difference, and Reducer With Involute Gear of Less-tooth Difference is placed in casing;
Driving member is that internal messing four shunts driving member, comprise driving wheel, shunting gear and center gear ring, driving wheel is located on involute planetary gear output shaft, shunt gear bilateral symmetry for two that are meshed with driving wheel to arrange, shunting gear engages with center gear ring, the axle of shunting gear is fixing on the supporting plate, and supporting bracket connects on the cover board, and cover plate is connected on the end face of involute planetary gear casing;
Center gear ring is connected with disk, and disk and main cylinder are integrally connected, and main cylinder relies on first and second bearing to be bearing in casing center circle endoporus, main cylinder jointed rod flange, drilling rod Flange joint auger stem.
The background technology of [beneficial effect] ratio, its beneficial effect is:
(1) the present invention four shunts the bending strength of modified ring gear, is about 1.5 times of the background technology " Novel high torque stake mechanomotive force head hard-tooth surface speed reducer " (201210558920.6) of two flow dividing structures;
