Abstract
The utility model relates to a main shaft lock of a megawatt blower, which is characterized in that the main shaft lock comprises a lock shaft of a main shaft, wherein a sleeve is sleeved at the end part of the lock shaft; a pin radially inserted into the lock shaft is mounted on the side wall of the sleeve; an axial long groove is formed on the surface of the lock shaft at the part corresponding to the pin; an internal thread hole is formed at the tail end of the lock shaft; a screw hole is formed at the bottom of the sleeve in the position corresponding to the internal thread hole; a screw is mounted in the screw hole; and a handwheel is mounted at the end part of the screw. After the lock shaft of the main shaft is reset, the pin is inserted into the axial long groove on the surface of the lock shaft to stop the lock shaft from rotating, thereby realizing the primary locking; and then the locking screw is used to fix the lock shaft of the main shaft at the tail part of the housing to stop the lock shaft from axially moving, thereby realizing the secondary locking. The double locking enables the locking to be firm, and ensures the normal rotation and generation of the blower.
Description
Technical field
The utility model relates to the lock spindle that a kind of MW class wind turbine group has double locking function, is mainly used in the spindle lock of MW class wind turbine group.
Background technique
Lock spindle is dead halt and the locking framework that prevents the wind wheel rotation.Only under the situation that main shaft and wind wheel do not rotate, the maintenance man just allows to enter wheel hub and carries out the work.But blower fan main shaft is in service in normal rotation, drive generator for electricity generation, definitely any interference can not be arranged.And lock spindle just becomes breakneck position, if under certain condition, the position groove of spindle lock is ineffective, and lock shaft moves forward, and enters fast in the brake lockhole, stops main shaft and rotates, and will cause great engine-damaged accident.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of double locking lock spindle function is provided, and locking firmly, can guarantee the lock spindle of the MW class wind turbine group of blower fan normal rotation generating.
The purpose of this utility model is to realize like this; A kind of lock spindle of MW class blower fan, it is characterized in that, described lock spindle comprises the lock shaft of main shaft, end at described lock shaft is set with sleeve, the latch that radially inserts lock shaft is housed on the sidewall of described sleeve, position on the surface of described lock shaft corresponding to described latch is provided with an axial elongated slot, afterbody at described lock shaft is provided with interior threaded hole, position in the bottom of described sleeve corresponding to described interior threaded hole also is provided with screw, in described screw, screw rod is housed, handwheel is housed in the end of described screw rod.
In order to make the lock spindle locking firm and easy to operate, optimized technical scheme is, described latch comprises U-shaped plug housing and the bolt rod on the sidewall that is installed in sleeve, the opening of described U-shaped plug housing is towards the sidewall of described sleeve, between described U-shaped plug housing and bolt rod, spring is housed, on the baffle ring of one end roof pressure in the U-shaped plug housing of described spring, the other end roof pressure is on the platen that is fixed on the bolt rod; Upper-end surface at described U-shaped plug housing also is provided with the yi word pattern opening, and the upper end that is positioned at described platen on described bolt rod is provided with and the corresponding yi word pattern projection of described yi word pattern opening.
The utility model, after the main shaft lock shaft resets, earlier latch is inserted in the axial elongated slot on lock shaft surface lock shaft can not be rotated, realize that one re-locks, lock shaft can not be moved vertically the afterbody that the main shaft lock shaft is fixed on housing with lock nut then, realize that second re-locks.The double locking mode makes locking firmly, can guarantee the generating of blower fan normal rotation.
Description of drawings
Fig. 1 is the structural representation of the lock spindle of the utility model MW class blower fan.
Among the figure: 1, lock shaft; 2, sleeve; 3, latch; 4, axial elongated slot; 5, interior threaded hole; 6, screw rod; 7, handwheel; 8, U-shaped plug housing; 9, bolt rod; 10, spring; 11, baffle ring; 12, platen; 13, upper-end surface; 14, yi word pattern opening; 15, yi word pattern projection.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
Referring to Fig. 1, the lock spindle of a kind of MW class blower fan that the utility model relates to, this lock spindle comprises the lock shaft 1 of main shaft, be set with sleeve 2 in the end of described lock shaft 1, the latch 3 that radially inserts lock shaft 1 is housed on the sidewall of described sleeve 2, position on the surface of described lock shaft 1 corresponding to described latch 3 is provided with an axial elongated slot 4, afterbody at described lock shaft is provided with interior threaded hole 5, position in the bottom of described sleeve 2 corresponding to described interior threaded hole 5 also is provided with screw, in described screw 5, screw rod 6 is housed, handwheel 7 is housed in the end of described screw rod 6.
The utility model is in order to make the lock spindle locking firm and easy to operate, preferred embodiment is, described latch 3 comprises U-shaped plug housing 8 and the bolt rod 9 on the sidewall that is installed in sleeve 2, the opening of described U-shaped plug housing 8 is towards the sidewall of described sleeve 2, between described U-shaped plug housing 8 and bolt rod 9, spring 10 is housed, on the baffle ring 11 of one end roof pressure in U-shaped plug housing 8 of described spring 10, the other end roof pressure is on the platen 12 that is fixed on the bolt rod 9; Upper-end surface 13 at described U-shaped plug housing also is provided with yi word pattern opening 14, and the upper end that is positioned at described platen 12 on described bolt rod 9 is provided with and described yi word pattern opening 14 corresponding yi word pattern projections 15.
When needs fixedly during lock shaft, at first with bolt rod 9 to pressing down, make its disconnected not being inserted in the axial elongated slot 4 on lock shaft 1 surface, the upper end yi word pattern projection 15 that is positioned at described platen 12 simultaneously on the bolt rod 9 also is inserted into the yi word pattern opening 14 of U-shaped plug housing upper-end surface 13, it is motionless its bolt rod to be blocked bolt rod 9 rotations 90 degree then, be rotatably installed in the screw rod 6 of sleeve 2 ends again, make in its tapped hole that screws in lock shaft 1 end.Just can be by aforesaid operations with lock shaft 1 dual locking.But when needing release, can be earlier the screw rod 6 of sleeve 2 ends be unclamped, bolt rod 9 is oppositely gone back to 90 degree again, this moment, bolt rod 9 resetted under the effect of spring 10, so far can finish the release work of lock shaft.
