Abstract
The utility model belongs to an equipment maintenance auxiliary tool which is adaptable to steam turbine maintenance of generation stations, in particular to a turbine manual turning gear. The turbine manual turning gear comprises a seat, the seat is equipped with a shaft through a bearing, one end of the shaft is fixedly equipped with a gear, and the other end of the shaft is a rectangular end. The U-shaped seat is formed by three steel plates, wherein the two vertical steel plates are equipped with holes, the bearing is arranged in the holes, and the shaft is arranged on the seat through the bearing. The utility model is simple in structure, convenient in mounting and dismounting, increases working efficiency, reduces labor intensity, and avoids personal injury accidents and equipment damage accidents.
Description
Technical field:
The utility model belongs to the overhaul of the equipments assistant tool, is applicable to the overhaul of steam turbine of power station, is specifically related to the manual jiggering instrument of steam turbine.
Background technique:
In the power station overhaul of steam turbine, the moving turbine rotor of dish is the work that often need do, because in maintenance, electric barring equipment is removed, can't carry out jiggering, this just needs manual jiggering, and manually jiggering generally has two kinds of jiggering forms, a kind of many people are coiled the movable vane wheel and are carried out jiggering, and another kind of the employing manually uses crowbar to prize jiggering gear jiggering.If first kind cooperates badly, the personal injury accident of hindering, scratching easily takes place to squeeze, second kind of easy damaged jiggering gear engagement face on the one hand, easy slippage when prizing on the other hand dodges the people to fall injured, is unfavorable for safety inspection.
Summary of the invention:
The utility model aims to provide a kind of both simple and convenient, is easy to on-the-spot dismounting again, can avoid taking place the manual jiggering instrument of steam turbine of personal injury accident and equipment damage accident again.
The realization the technical solution of the utility model is: comprises base, by bearing axle is set on the base, and the end fixed installation gear of axle, the other end of axle is the rectangle termination.
Base constitutes " U " font by three block plates, wherein on two blocks of perpendicular steel plates the hole is set, and bearing is set in the hole, and axle is arranged on the base by bearing.
The utility model is simple in structure, and easy accessibility has improved working efficiency, has reduced labor intensity, has avoided personal injury accident and equipment damage accident.
