Abstract
The invention provides a blade locking device of a wind driven generator. The device comprises a connection plate; and a supporting plate is welded at the side of the connection plate. The device is characterized in that a welding locking block is arranged on the connection plate; the welding locking block is matched with the connection plate through a linked-type structure; a pair of symmetrical compression bolts are formed on the connection plate after penetrating through the welding locking block; the welding locking block can slide along the compression bolt; a pair of symmetrical dual-use bolts are formed on the connection plate after penetrating through round holes of the welding locking block; threaded holes matched with the dual-use bolts are formed on the supporting plate; and the dual-use bolts can penetrate through the threaded holes and can be fixed through nuts, so that the top part of the dual-use bolt butts against the welding locking block. The device is reliable in structure, strong in bearing capacity and excellent in adaptability.
Description
Technical field
The present invention relates to the locking field of wind-driven generator, specifically, relate to a kind of blade of wind-driven generator locking device.
Background technique
The wind generator set blade locking device is the important component part of blower fan safety component, has important function when blower fan is safeguarded.
At present, the structure of wind generator set blade locking device mainly adopts the pin axle type structure, and part adopts push-pull structure.But the pin axle type structure can't realize that along the moving radially of pitch variable bearings to such an extent as to bearing pin can't be fitted with the pitch variable bearings inner ring, when fitful wind blew blade, impact loading made bearing pin deform easily on bearing pin; And employed plug-type blade shrinking device is that plain bolt bears shearing force in the market, must often change bolt.
Increase along with wind-driven generator kludge quantity, later maintenance cost also improves gradually, and the rising along with power level, blade locking device is constantly increased by load, original blade locking device can not fully guarantee the safety of blower fan, so original blade locking device can not satisfy the needs of blower fan.This is the deficiencies in the prior art part.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of blade of wind-driven generator locking device, and this apparatus structure is reliable, bearing capacity is strong, adaptability is good.
The present invention adopts following technological scheme to realize goal of the invention:
A kind of blade of wind-driven generator locking device, comprise connecting plate, the side of described connecting plate is welded with dunnage, it is characterized in that: be provided with the welding locking block on the described connecting plate, described welding locking block matches with described connecting plate by the of bonding structure, the hold-down bolt of a pair of symmetry passes described welding locking block and is installed on the described connecting plate, described welding locking block can slide along described hold-down bolt, the circular hole that the dual-purpose bolt of a pair of symmetry passes described welding locking block is installed on the described connecting plate, be provided with the tapped hole that cooperates with described dual-purpose bolt on the described dunnage, described dual-purpose bolt also can pass described tapped hole and fix by nut, so that described welding locking block is withstood at the top of described dual-purpose bolt.
As the further restriction to the technical program, described welding locking block comprises slide block, is provided with ejector pin on the described slide block, and described ejector pin connects two supporting frames, also is provided with long sliding hole on the described slide block, and described hold-down bolt passes described long sliding hole.
As the further restriction to the technical program, described hold-down bolt passes packing ring and described long sliding hole.
As the further restriction to the technical program, described of bonding structure comprise the groove that is arranged on the described connecting plate and with described slide block on its protruding part that matches.
Compared with prior art, advantage of the present invention and good effect are: the present invention has avoided hold-down bolt to bear shearing force by the of bonding structure between the slide block of connecting plate and welding locking block, and application area is wider; Secondly, by adjusting the position of dual-purpose bolt, can conveniently realize the switching of working state and off working state, by the position of adjusting dual-purpose bolt ejector pin and the pitch variable bearings ring gear of welding locking block are fitted tightly, avoided the impact of pitch variable bearings ring gear to blade locking device; Avoided the frequent hold-down bolt, both reduced maintenance cost, also made faster and more convenient operation.Avoided behind the nut screwing clamping causing dual-purpose bolt looseness because of vibrations.
