Planetary-hypocycloid double-annular-plate pile machine reducer with oil temperature alarm function

Abstract

The invention relates to the technical field of speed reduction of a pile machine and provides a planetary-hypocycloid double-annular-plate pile machine reducer with an oil temperature alarm function. The planetary-hypocycloid double-annular-plate pile machine reducer comprises a box body, motors, a cover plate and a transmission part, wherein the transmission part comprises eccentric bearings, annular plates, hypocycloid gear rings and cycloidal gears; the four eccentric bearings are respectively arranged on the output shafts of two NGWs; the eccentric bearing comprises rolling bearings and eccentric sleeves; the phase difference of two eccentric sleeves is 180 degrees; the hypocycloid gear rings are matched with the middles of the annular plates; the planetary-hypocycloid double-annular-plate pile machine reducer is characterized in that an oil temperature sensor is arranged in the box body; one or two labyrinth vent hoods are arranged on the cover plate; the motors are invertedly arranged below the box body; the shafts of the motors are connected with the NGWs; the bottommost eccentric sleeve is supported on a thrust bearing; the cycloidal gears are connected with a main cylinder; the main cylinder is supported in the box body through bearings; the main cylinder is connected with a flange and the flange is connected with a drill rod. The planetary-hypocycloid double-annular-plate pile machine reducer has the benefits as follows: the dynamic state of the reducer can be mastered according to oil temperature changes, the air pressure inside the box body and the air pressure outside the box body are balanced through the vent hoods, and since the motors are arranged invertedly, the overturning moment of the pile machine is reduced and the accident probability is reduced; since quadrupole motors can replace original sextupole motors for speed reduction of the NGWs, so that the cost and the weight are reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of pile machine deceleration, and relates to an oil temperature alarm planetary-hypocycloid two-ring sheet pile machine reducer. 【Background technique】 [0002] With the rapid development of my country's economy, construction machinery has been widely used. As a basic construction, long screw pile machines are scattered all over the world, so that the demand for pile machines has increased sharply. Said: "There is even a phenomenon of queuing up to pick up the goods at the pile driver factory with a large amount of money. The three-ring reducer manufacturer that matches the power head with the pile driver factory has increased its output so that each pile driver manufacturer can supply a complete set Goods." (See Science and Fortune, 2013.01) [0003] Background technology: China Patent Office has published the following patents successively: [0004] (1) Power head of screw pile machine (201020300223.7) ...

AI Technical Summary

Problems solved by technology

The disadvantage of the ventilation hood (JB1130-70) is: the exhaust hole is too small (the maximum diameter of the straight hole in the box is only Φ20mm, and the small hole outside the box that is in contact with the environment is even smaller)

For the pile driver reducer, the disadvantages of the ventilation cover (JB1130-70) are even more obvious: open-air operation, large dust, and the small exhaust holes will gradually become smaller after the dust sees water, so that the ventilation cover will gradually lose the inside and outside of the box. Pressure balance, when the air pressure inside the box is greater than the air pressure outside the box, the lubricating oil will leak from the seal;

[0011] (c) Disadvantages of top-mounted dual motors: Due to the harsh working conditions on the construction site, most operators do not have maintenance equipment and skills. It is difficult to remove the heavy motor and reducer, so repair and maintenance are difficult, and the cap on the top of the motor is difficult to waterproof. more difficult to dust

[0012] (1) On April 26, 2006, a pile driver suddenly collapsed in a construction site on Xiangheyuan Road outside Dongzhimen, Beijing, causing the death of two workers
