Description

Planet hypocycloid two ring flat-plate stake machine retarder is inverted by motor

[technical field]

The present invention relates to Dual-motors Driving stake machine braking technique field, planet hypocycloid two ring flat-plate stake machine retarder is inverted by a kind of motor.

[background technique]

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 speed reducer (201410335368.3)

(7) screw rod pile machine is with high pulling torque power head device (201420625553.1)

The common Problems existing of background technique is: dual-motor up-set type is installed, and makes a machine center of gravity high, and tilting moment is large, and stake machine exists unstable hidden danger, and the probability of stake machine generation overthrow accident can be high.This is because:

Stake machine 23 meters of screw pile driver columns allow angles of inclination to only have 3 °, and working 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 pile driver collapses suddenly, and accident causes two workman's death.Pile driver 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 pile driver has just fallen, and pile driver also collapses thereupon, just in time pounds below with it two workmans.Field Force claims: " estimation is that the soil below pile driver is too loose, and ground is also uneven, so pile driver 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 pile driver is tumbled suddenly, not only press the factory building in roadside that collapsed, more result in a uncle injured, why pile driver can tumble suddenly, and mainly too pine, pile driver 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 pile driver 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 up-set type dual-motor of background technique:

(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 retarder 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.

" Novel high torque stake mechanomotive force head hard-tooth surface speed reducer " (201210558920.6) technical characteristics in background technique is:

" (two) helical gear shaft engages with central gear " now illustrates the deficiency of this technology 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.

[summary of the invention]

Planet hypocycloid two ring flat-plate stake machine retarder is inverted by a kind of motor that the object of the invention is to provide lower than background technique cost, installation difficulty is little, easy to maintenance and safe and reliable.

[technological scheme]

Two motors upside-down is connected to below casing, and arranges about output center bilateral symmetry;

Two motors axle stretch end connects NGW planetary reducer, and NGW planetary reducer is placed in casing;

Driving component comprises capacity eccentric bearing, ring flat-plate, hypocycloid gear ring and cycloid wheel, wherein:

Described capacity eccentric bearing is that four identical, points are located in both sides NGW planetary reducer output shaft extension, and capacity eccentric bearing comprises rolling bearing and the eccentric bushing being contained in brearing bore, two capacity eccentric bearing phase differences 180 °;

Ring flat-plate is first and second ring flat-plate that two panels is identical, and two ring flat-plates rely on its monosymmetric bearing hole to coordinate with capacity eccentric bearing cylindrical and support, first and second pipper close-fitting hypocycloid gear ring, and hypocycloid gear ring engages with cycloid wheel;

Cycloid wheel is connected with main cylinder neck, 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 ZZSH type stake machine three-ring speed reducer special of YB/T079-1995 " three-ring speed reducer ", what adopt is three ring flat-plates, 120 °, phase angle, major defect is that technology capability is poor, must deflect 120 ° of processing between three ring flat-plates, trisection precision is difficult to control, phase difference 180 ° between two ring flat-plates, assemble conversely after processing, much simple and easy.

The background technique of [beneficial effect] ratio, its beneficial effect is:

(1) background technique just must can be picked up and looks into retarder 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;

(2) reduce the tilting moment of a machine, thus reduce overthrow accident probability;

(3) double motor upside-down structure is beneficial to motor waterproof, has stopped the accident of burning because of water inlet in motor coil.

(4) technique effect of first order NGW planetary reduction gear: is quadrupole motor can replace the 6-pole motor of first wife, and motor price is low, weight is also light; Two is the theoretical service lives that improve capacity eccentric bearing; Three is to make ring flat-plate not produce vibration.
