Description
Technical field
The utility model relates to the barring gear before a kind of huge revolving start-up of power plant.
Background technique
For huge revolving power equipments such as large-scale compressor, large-scale gas-turbines, before starting, must coil first several lower large flywheels, to get rid of inside or some outside faults, this just needs barring gear.Barring gear in the past is mainly take electronic as main, it is that the universal disc vehicle motor drives small gear, small gear and large flywheel engagement (will process the gear teeth on the large flywheel), the drive gearwheel rotates, so just have some problems: at first electric barring needs electricity to drive, be unfavorable for so energy-conservation, and at some inflammable and explosive site environments, requirement to motor is also very high, has virtually also strengthened cost; Secondly: large flywheel will process the gear teeth, and the Gear Processing precision is high, and cost also increases simultaneously; Last electric barring need dispose speed reducer, leading screw etc.Package unit is bulky, and the installing space that needs is also large, and the operating space also is restricted at the scene.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of energy-conserving and environment-protective, handling safety, cost is low, volume is little, make the front barring gear of huge revolving start-up of power plant simple, easy and simple to handle.
The technological scheme that addresses the above problem is: the barring gear before this huge revolving start-up of power plant, it comprises base, cylinder, guide rod, jiggering head, cylinder links to each other with base by bearing pin, guide rod comprises guide rod, blue dish, positioning block, blue dish is fixed on the cylinder, positioning block is fixed to the jiggering head, and guide rod is fixed on the positioning block and slides along the pilot hole of blue dish, and the jiggering head rotates at the front end of the piston rod of cylinder and with the flywheel of barring.
Gas is introduced cylinder by pipeline, gas push piston movement in the cylinder, when moving to certain position, the jiggering head of piston rod front end will extend in the end-face hole of flywheel, the flywheel driven motion, when moving to certain position, the jiggering head will be thrown off with flywheel and be finished jiggering work, so this barring gear energy-conserving and environment-protective, handling safety, cost is low, volume is little, it is simple, easy and simple to handle to make.
