Abstract

The invention discloses a speed reducer structure of a lifting type platform lifting system. The speed reducer structure of the lifting type platform lifting system comprises a pile box and a speed reducer. The speed reducer comprises a helical gear speed reducer body and a planet gear speed reducer body. The input shaft of the helical gear speed reducer body is connected with a motor, the output shaft of the helical gear speed reducer body is connected with the planet gear speed reducer body, and a whole formed by the motor, the helical gear speed reducer body and the planet gear speed reducer body is arranged on the side face of the pile box in a U-shaped mode. The speed reducer is reasonable and compact in structure, light in weight, stable in operation, and capable of effectively utilizing space of the pile box, reducing the weight of a platform, and meeting the using requirement of the lifting system.

Description

technical field [0001] The invention relates to a lifting system of a lifting platform, in particular to a structure of a deceleration device of the lifting system of a lifting platform. Background technique [0002] The lifting platform is a mobile offshore engineering platform used for offshore energy exploitation and exploration. Its main components are the working platform, the legs supporting the platform, the lifting system that controls the lifting of the working platform and the locking system after the working platform is positioned. . The lifting system is mainly composed of motor, reduction device, lifting gear shaft assembly and so on. [0003] The deceleration device of the lifting system is required to achieve a large deceleration ratio and output a large torque, and its internal structure must have a certain bearing capacity to meet the strength requirements. However, its design and manufacture are limited by conditions such as platform weight and space. The...
