Abstract
Large-scale hydrogenerators belong to heavy and major equipment of special purposes. Hydropower stations have no machine tool that can process such heavy and major components on site. Therefore, processing equipment special for site processing of a hydrogenerator rotor spider stud needs to be developed. In order to make up the deficiency, the invention provides special and convenient processing equipment specifically for large-scale hydrogenerator rotor spider studs.
Description
Technical field
The invention belongs to the hydrogenerator manufacture field.
Background technology
Large-sized water turbine generator belongs to heavy, great equipment special.Its diameter of rotor field spider in the hydrogenerator is more than ten meters; Its height is more than 3.5 meters; Its weight is more than 160 tons, and so big and heavy rotor field spider is that highway or railway all can't transport at a distance; So the rotor field spider of large-sized water turbine generator adopts the mode of distinguish to transport, wait to arrive behind the power station assembly welding again.Yet because welding deformation, the precision of postwelding generator rotor support does not reach installation requirements, so rotor field spider also need carry out machined to satisfy the requirement of installation dimension after assembly welding is accomplished.
The scene, power station does not have to process the lathe of heavy type like this, great parts.Therefore, need a kind of process equipment that is specifically designed to processing rotor support power generator stud of exploitation in the job site, power station.
This equipment must satisfy following requirement:
1, this equipment does not have fixing machine tool basic, and being suspended to by the driving in power station needs the position of processing to process.
2, this equipment itself need have three degree of freedom, can conveniently accomplish the adjustment of vertical and horizontal plane.
3, this apparatus processing efficient must satisfy the site construction schedule requirement, the processing with a rotor support power generator stud of domestic demand completion in promptly one month.
4, the machining accuracy of this equipment need satisfy linearity 0.02/1000mm.
Summary of the invention
In order to remedy the deficiency of building-site working ability, the invention provides a kind of special use, large-sized water turbine generator rotor field spider stud special processing equipment easily.
This equipment comprises: the framework that crossbeam, base, two column constitute, lifting platform is located at the milling head on the lifting platform and is installed on the transmission system on the crossbeam.Transmission system by motor through the gear steering box with transmission of power to power transmission shaft, drive bevel gear set by power transmission shaft again, bevel gear set drives screw mandrel, at last by the rotation of screw mandrel drive lifting platform do about rectilinear motion.
This equipment further comprises: be arranged at the cross slid platform on the lifting platform, milling head moves at the dovetail groove that feed screw nut pair drives the lower edge cross slid platform.
Further comprise: be arranged at the inboard line slideway of column, lifting platform moves along above-mentioned line slideway.
Further comprise: be arranged at the rotor field spider jockey on the column, form by support arm, handle, briquetting and clamping screw.
Further comprise: level(l)ing device, form by screw rod, locking nut and the briquetting be located on the base.
Further comprise: the counter weight device that is connected through pulley with above-mentioned lifting platform.
The present invention is owing to adopted the frame for movement and the control mode of above-mentioned special use; Make building-site machining large rotor support power generator stud become easily, quick, when guaranteeing the hydrogenerator installation requirement, also a kind of new method is provided for the production of hydrogenerator, installation.
