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, coal bed gas and shale gas equipment, and relates to a power input connection device for a fracturing pump. Background technique [0002] The fracturing pump is the core supporting unit of the fracturing vehicle. Its input end and the gearbox are connected to power through the drive shaft. Since the fracturing pump and the gearbox are fixed and installed on the transport chassis through separate supports, in order to ensure their respective It is convenient to disassemble and maintain, and the transmission shaft must adopt a retractable structure, so that the transmission shaft needs to ensure a certain length. [0003] In recent years, fracturing vehicles have shown a trend of high power, long working hours and high pressure, and the power, quality and overall dimensions of the installed engines, gearboxes and fracturing pumps are also increasing. Restricted by roads in mountainous and hilly ...
