Cycloid external meshed four-shunt pile machine speed reducer capable of realizing oil temperature alarming

Abstract

The invention relates to the technical field of pile machine speed reduction, and discloses a cycloid external meshed four-shunt pile machine speed reducer capable of realizing oil temperature alarming. The pile machine speed reducer comprises a box body, motors, a cover plate and a transmission part, and is characterized in that an oil temperature sensor is arranged inside the box body; a labyrinth type vent hood is arranged on the cover plate; the two motors are inversely connected to the lower part of the box body; the shaft extension end of each motor is connected with a cycloid speed reducer; the transmission component comprises driving wheels, shunt gears and a center gear ring; each driving wheel is arranged on the output shaft of the corresponding cycloid speed reducer; the shunt gears are arranged symmetrically on the two sides; shafts of the shunt gears are fixed on support plates; each support plate is connected onto the end face of a housing of each cycloid speed reducer; the center gear ring is in flanged connection with a main cylinder; the main cylinder is supported in the box body by using bearings, and is connected with a drill rod flange; the drill rod flange is connected with a drill rod. The pile machine speed reducer has the benefits as follows: the speed reducer dynamic state can be mastered according to the oil temperature variation; the inside and outside of the box body reach air pressure balance by virtue of the labyrinth type vent hood; through the adoption of the inverse motors, the overturning moment of a pile machine is reduced, the incidence of overturning accidents is reduced, and the bearing force is high by virtue of the four-shunt manner; compared with carburization manner, the quenching and tempering manner for internal gear ring has the advantages that the difficulty is low and the cost is low.

Description

【Technical field】 [0001] The invention relates to the technical field of pile driver deceleration, and relates to an oil temperature alarm cycloid outer meshing four-shunt pile driver 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) [000...

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
