Description
Technical field
The present invention relates to a kind of Wind turbines modular construction, specifically a kind of elastic support of wind turbine gearbox structure and elastomer replacing options.
Background technique
Existing double-fed wind power generator group, usually by main shaft, main bearing, advance bearing, the parts composition Transmitted chainss such as gear-box, the toggle of gear-box is supported by elastic support rubber element, traditional this double-fed wind power generator group, because its structural design is unreasonable, when changing elastic support, upwards lift to reduce gear-box toggle damage is caused to bearing, usually need to disconnect coupling, propelling bearing is unclamped, its fixing bolt upwards regulates 6-15mm, unclamp gear case elastic support framework clamping bolt successively, then use separating jack by gear-box toggle upwards jack-up holding down bolt rise amount maybe will be advanced to strengthen, utilize blade hub end to conduct oneself with dignity toggle is raised, toggle is separated (pre compressed magnitude namely eliminating elastic element) with lower elastic support, the elastic element that can more renew.
Simultaneously, all there is oneself design in existing blower fan producer, also just result in interface size, mounting type there are differences, also there is the situation that frame cannot install separating jack additional thus, this unit changes gear-box elastic element to be needed to adopt little loop wheel machine maybe the propelling bearing amount of unclamping to be strengthened, and utilizing hub end to conduct oneself with dignity could carry on gear-box toggle, and the workloads such as installation steps, replacing maintenance, fastening piece locking are larger, very loaded down with trivial details, people's number is many and efficiency is very low.And unclamp cardan shaft bearing clamping bolt, safeguard more changing jobs under being applicable to low wind speed operating mode, in the area that the better wind speed of wind regime is larger, use which to change and also there is certain potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple to operation, changes efficiency high, just can complete elastic support of wind turbine gearbox structure and the elastomer replacing options of elastic element replacing without the need to removal torque arm.
In order to solve the problems of the technologies described above, elastic support of wind turbine gearbox structure of the present invention, comprise and being arranged in frame for installing the base plate of lower elastic element, can coordinate with base plate and to install and for the crossbeam of installing elastic element and the support post be arranged between base plate and crossbeam, frame, base plate, support post and crossbeam can be connected and fixed by clamping bolt, connected by connecting bolt between crossbeam and support post, crossbeam is also provided with crossbeam and support post can be made to depart from eject screw; The upper and lower end face of base plate has at least on one of them end face and be provided with movable pad, also comprise and base plate, crossbeam, support post and lower movable pad can be carried out pre-assembled pre-assembled bolt, base plate, crossbeam, support post and movable pad can be undertaken pre-assembled by pre-assembled bolt.
Described support post is provided with four, and four support posts are separately positioned on the position, four corners between base plate and crossbeam.
The described screw that ejects is provided with two right, and two are arranged on the diagonal of crossbeam two corners to the described screw that ejects, and two eject in screw all for settling liftout bolt described.
Be provided with lower movable pad between described base plate and frame, described lower movable pad has U-groove bevel.
Movable pad is provided with between described base plate and support post; Described upper movable pad also has U-groove bevel.
An elastomer replacing options for above-mentioned elastic support of wind turbine gearbox structure, is characterized in that, comprise the following steps:
When lower elastic element is changed, clamping bolt is unclamped, now keep support post to be connected with crossbeam, clamping bolt unclamps rear upper deformation of elastic components and recovers, and occurs gap between support post and movable pad, now movable pad is taken out, then unclamp pre-assembled bolt, because movable pad is removed, between base plate and support post, will gap be occurred, along with lower elastic element pre compressed magnitude is eliminated, just lower elastic element can be changed.
When upper elastic element is changed, first unclamp the connecting bolt between support post and crossbeam, down twist crossbeam ejecting the liftout bolt settled in screw, along with the head of liftout bolt is emerged, to make to occur gap between crossbeam and support post, when this gap exceedes upper elastic element pre compressed magnitude, elastic element can be replaced with.
After adopting above-mentioned structure and method, can by crossbeam due to what arrange, the pre-assembled bolt that support post and base plate carry out pretension and the movable pad that can take out, thus by coordinating the distortion of upper elastic element to change lower elastic element, the liftout bolt being provided with connecting bolt and crossbeam and support post can be made to depart between support post and crossbeam simultaneously, coordinate by connecting bolt and liftout bolt thus and replace with elastic element smoothly, by such structural design, when the elastic element of gear case elastic support needs to change, completely no longer need to disconnect coupling, more do not need to unclamp the replacing operation that cardan shaft bearing clamping bolt just can realize elastic element smoothly, its smart structural design is reasonable, simple to operation, substantially increase replacing efficiency.
