AI Technical Summary
Technical Problem
The existing steam turbine disc wheel device cannot automatically disengage when the turbine rotor is reversed, resulting in damage to the disc wheel device or the rotor disc wheel.
Method used
A two-way tripping method for steam turbine trolley device is designed. By adding oil cylinders and electronic components to the trolley device, the tripping of the small spiral gear is controlled by using the oil cylinder pressure to achieve automatic tripping when the forward and reverse rotors rotate.
Benefits of technology
The automatic disengagement of the meshing gear of the turbine during forward and reverse rotation is realized, avoiding damage to the carriage device and rotor due to reversal failure, and improving the safety and service life of the device.

Abstract
The invention discloses a two-way tripping method and device for a steam turbine barring gear, and relates to the technical field of steam turbine barring, and the two-way tripping method for the steam turbine barring gear comprises the steps that barring is achieved through a barring operation step, forward tripping is achieved through a forward tripping step, and reverse tripping is achieved through a reverse tripping step. The next work is prepared through the recovery step so as to solve the problem that when a steam turbine rotor rotates reversely at present, an engaged gear of a turning gear cannot be automatically disengaged, on the basis of spiral gear connection, an oil cylinder and matched electronic components are additionally arranged, the requirement that normal turning is automatically tripped and quits turning can be met, and the turning gear can be prevented from being disengaged automatically. And when a reverse rotation fault occurs in a shaft system of the unit in a turning state, the purpose that the meshing gear is automatically disengaged and quits turning is achieved, the meshing gear can be automatically disengaged when the turning gear rotates forwards and reversely, and damage to the turning gear and a rotor due to reverse rotation of the unit is avoided.
