External gearing four-splitting pile machine speed reduction device with motors placed upside down

Abstract

The invention relates to the technical field of pile machine speed reduction, in particular to an external gearing four-splitting pile machine speed reduction device with motors placed upside down. The device comprises a box body, the motors, a cover plate and a transmission component and is characterized in that the shaft extension ends of the motors are connected with a planetary reducer, the motors are connected to the lower side of the box body upside down, and the planetary reducer is arranged in the box body; the external gearing four-splitting transmission component comprises a driving wheel, splitting gears symmetrically arranged on the two sides, and a center gear ring, a mandrel of each splitting gear is fixed to a supporting plate connected to a cover plate of a planetary reducer shell, and the center gear ring is connected with a disc; the disc is connected with a main cylinder, the main cylinder is supported by inner holes of the box body through two bearings, and the main cylinder is connected with a drill rod flange. The device has the beneficial effects that due to the fact that the two motors are placed upside down, the motors and the speed reducer can be dismantled easily, and maintenance is convenient; the probability of tipping accidents is reduced; water resistance and dust resistance of the motors are improved; bearing capacity is higher under the external gearing four-splitting condition compared with the two-splitting condition, the difficulty of the inner gear ring technology is lower than that of the carburize-grinding technology, cost is low, and cracking does not happen easily.

Problems solved by technology

[0010] The problem of the background technology is: the dual motors are installed on top, so the center of gravity of the pile driver is high, the overturning moment is large, the pile driver has potential instability, and the pile driver may overturn.

[0013] (2) On September 07, 2006, at the construction site in front of the Hechuan Building at No. 2010 Yishan Road, Shanghai, a pile driver suddenly overturned, not only crushing the factory building on the side of the road, but also causing an old man to be injured. So it will suddenly tip over, mainly because the soil is too loose and the center of gravity of the pile driver is unstable;

[0016] (1) Due to the harsh working conditions at the construction site, most of the operators do not have maintenance equipment and skills. When a fault occurs, it is difficult to remove the heavy motor and reducer, so it is difficult to repair and maintain;

[0017] (2) Due to the harsh working conditions at the construction site, the cap of the motor is difficult to waterproof and dustproof
