Abstract

The invention discloses a power input connection device of a fracturing pump. The power input connection device of the fracturing pump comprises a transitional connection plate; an input shaft of a gear case of the fracturing pump is sleeved with the inner circumference of the transitional connection plate in a sliding mode; the outer circumference of the transitional connection plate is sleeved with a connecting flange II in a sliding mode; the connecting flange II is fixedly connected with an end face flange arranged on one side of a coupler I, and an end face flange arranged on the other side of the coupler I is fixedly connected with an end face flange arranged on one side of a coupler II; and an end face flange arranged on the other side of the coupler II is fixedly connected with a shaft end flange of an output shaft of the gear case. According to the power input connection device of the fracturing pump, the correctness and the reliability of mounting are guaranteed, mounting and dismounting can be conducted conveniently, the structure is compact, and the mounting distance between the input shaft of the fracturing pump and the gear case can be reduced.

Description

Technical field [0001] The invention belongs to the technical field of petroleum, coalbed methane and shale gas equipment, and relates to a fracturing pump power input connection device. Background technique [0002] The fracturing pump is the core supporting unit of the fracturing truck. Its input end is connected with the gearbox to connect to the power through the drive shaft. Because the fracturing pump and the gearbox are fixedly installed on the transport chassis through separate supports, in order to ensure their respective installation and It is easy to disassemble and maintain, and the transmission shaft needs to adopt a retractable structure, so that the transmission shaft needs to ensure a certain length. [0003] In recent years, the fracturing truck has shown a trend of high power, long working hours and high pressure. The power, quality and dimensions of the installed engine, gearbox and fracturing pump have also been increasing. Limited by roads in my country’s moun...
