Inner gearing four-split pile driver reducer with inverted motors

Abstract

The invention relates to the technical field of pile driver reduction, and discloses an inner gearing four-split pile driver reducer with inverted motors. The inner gearing four-split pile driver reducer comprises a box body, motors, cover boards and inner gearing four-split transmission parts; the inner gearing four-split pile driver reducer is characterized in that extension ends of the motors are connected with double-cycloid reducers; the motors are connected with the lower part of the box body in an inverted manner; the double-cycloid reducers are arranged in the box body; each inner gearing four-split transmission part comprises driving wheels, bisymmetric splitting gears and a center gear ring; mandrels of the splitting gears are fixed on a support plate; each support plate is connected with each cover board of a double-cycloid reducer casing; each center gear ring is connected with a disk; each disk is connected with a main cylinder; each main cylinder is supported in an inner hole of the box body by virtue of two bearings; each main cylinder is connected with a drill pipe flange. The inner gearing four-split pile driver reducer with the inverted motors has the beneficial effects that the double motors are inverted, so that the motors and the reducer are easy to dismantle and convenient to repair and maintain; the overthrow accident probability is reduced; waterproofing and dustproofing of the motors are facilitated; the carrying capacity of the inner gearing four-split mode is higher than that of a two-split mode; the inner gear ring process is small in carburizing difficulty and gear grinding difficulty and low in cost; and the inner gearing four-split pile driver reducer is not easy to crack.

AI Technical Summary

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
