Description
[technical field]
The present invention relates to a machine braking technique field, a kind of oil temperature warning planet-cycloid Fourth Ring sheet pile machine retarder.
[background technique]
Along with the fast development of China's economy, engineering machinery is widely used, based on build long spire stake machine spread all over the place, so that stake machine demand is anxious to be increased, and claims according to paper " Novel high torque stake mechanomotive force head hard-tooth surface speed reducer ": " whole nation even occurs holding the phenomenon of a large amount of payment for goods to the queuing delivery of cargo of stake machine host factory.Quantum of output is strengthened especially, so that the complete supply of material of Ge Zhuan machine host producer with the three-ring gear reducer producer of stake machine host factory supporting unit head." (seeing science and wealth, 2013.01)
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) screw rod pile machine is with high pulling torque power head device (201420625553.1)
But ", along with the quick growth of three-ring gear reducer amount, as the crucial transmission part of unit head, the problem points come out gets more and more, and this machine service cycle is long, and maintenance price is expensive." (paper: Novel high torque stake mechanomotive force head hard-tooth surface speed reducer)
There is following problems in background technique:
A () working life is short, that damages first can not predict: 2013, Jiangsu speed reducer company damages stake machine speed reducer to be repaired four, subsequently, Lai Santai is drawn successively again during short tens days, open discovery: in casing, have foul everywhere, comprise metallic dust, mud powder, bearing wear, gear failure.The national conditions of China are, individual piling works team accounts for main flow, and most of owner's financial strength is not strong, can not the high speed reducer of stock's valency, they worry, and it is desirable to repair as soon as possible, be afraid of that engineering promise breaking loses order, they wish that designer can solve a technical barrier for machine speed reducer config failure prior-warning device;
B the leakage of oil of () speed reducer output shaft sealing surface, main cause is vent hood: three during the last ten years, and China gear expert and manufacturing enterprise do not have the effect of the slight vent hood of attention one.(JB1130-70) that Qin great Tong " Modern mechanical design handbook " (first edition in 2011) rolls up the vent hood structure of 3.15-15 page and exhaust port size and " mechanical design handbook " (1980 editions, in, 817 pages) is just the same.The shortcoming of vent hood (JB1130-70) is: exhaust port too small (in case, maximum straight hole aperture is only Φ 20mm, and case aperture that is outer and environmental exposure is then less).Obvious especially for the shortcoming of stake machine speed reducer vent hood (JB1130-70): open work, dust is large, exhaust hole can be made after dust water breakthrough slowly to diminish, so that vent hood slowly loses casing internal and external pressure balance, when case internal air pressure is greater than air pressure outside case, lubricant oil just leaks from sealing;
(c) up-set type dual-motor shortcoming: because building site operating mode is severe, operator scarcely possesses maintenance of equipment and technical ability, and heavy motor and retarder are difficult to tear open, and thus keep in repair, maintain difficulty, motor tip cap is difficult to waterproof, more difficult dust-proof.Up-set type dual-motor center of gravity is high, and tilting moment is large, overthrow accident can occur.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.Field Force claims: " estimation is that the soil below pile driver is too loose, and ground is uneven, so pile driver just can collapse.”
(2) 2006 years 09 month 07 day, mansion, YiShan Road,ShangHai No. 2010 Hechuans was in front of the door on building site, and a pile driver is tumbled suddenly, and 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 technical characteristics of background technique (2) " Novel high torque stake mechanomotive force head hard-tooth surface speed reducer " (201210558920.6) is: (two) helical gear shaft engages with central gear, and the deficiency 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.
[summary of the invention]
The object of the invention is to provide a kind of: can give the alarm when oil temperature is increased to critical value; Improving vent hood makes air pressure balance Performance Ratio prior art vent hood (JB1130-70) more reliable; Changing overhead motor structure is upside-down structure, reduces a machine center of gravity, thus can reduce accident rate, a kind of oil temperature warning planet-cycloid Fourth Ring sheet pile machine retarder.
[technological scheme]
The present invention adopts and partly buries toothing cycloid, and the general pair of fulcrum type of its bearing capacity ratio can improve 40 ~ 50%, partly buries toothing and discusses and see " mechanical design handbook " and roll up 3.174-129 page.Technological scheme is as described below:
