Motor-inversed inner engaging four-shunting piling machine decelerator

Abstract

The invention relates to the technical field of piling machine deceleration. A motor-inversed inner engaging four-shunting piling machine decelerator comprises a housing, motors, a cover plate and an inner engaging four-shunting transmission member. The motor-inversed inner engaging four-shunting piling machine decelerator is characterized in that the shaft extension end of each motor is connected with an involute small-tooth-difference decelerator; the motors are connected with the lower portion of the housing in a reversed manner; the involute small-tooth-difference decelerator is arranged in the housing; the inner engaging four-shunting transmission member comprises a driving wheel, shunting gears which are symmetrical at two sides, and a central tooth ring; the mandrels of the shunting gears are fixed on a supporting plate; the supporting plate is connected with the cover plate of the housing of the involute small-tooth-difference decelerator; the central tooth ring is connected with a disc; the disc is connected with a main cylinder; the main cylinder is supported in the inner hole of the housing by means of two bearings; and the main cylinder is connected with a drilling rod flange. The motor-inversed inner engaging four-shunting piling machine decelerator is advantageous in that reverse mounting of the two motors realizes easy detachment between the motors and the decelerator, convenient mending and convenient maintenance; possibility of an overturning accident is reduced; and waterproof and dustproof performances of the motors are facilitated; the carrying capability of the inner engaging four-shunting manner is higher than that of two-shunting manner; the difficulty of an inner tooth ring technique is lower than that of a grinding tooth carburizing technique; and furthermore low cost and no easy cracking are realized.

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
