Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: a wind wheel locking disc of a wind turbine generator comprises a locking disc main body 1, a main shaft 3 and a screw 7, wherein lightening holes 2 are uniformly formed in one end of the locking disc main body 1, the main shaft 3 penetrates through the middle position of one end of the locking disc main body 1, the central axis of the main shaft 3 is overlapped with the central axis of the locking disc main body 1, and the main shaft 3 and the locking disc main body 1 form a relative rotation structure, so that when the main shaft 3 is not locked, the locking disc main body 1 cannot obstruct the normal rotation work of the main shaft 3;

a mounting ring 4 is fixed at one end of a locking disc main body 1, a first groove 5 is uniformly formed in the edge of the locking disc main body 1 close to one end of the mounting ring 4, a threaded hole 6 is reserved in one side of the interior of the first groove 5, a screw 7 is arranged in the threaded hole 6, an oil hole 8 is formed in the interior of the threaded hole 6, the central axis of the screw 7 and the central axis of the threaded hole 6 are mutually overlapped, and the screw 7 and the threaded hole 6 are in threaded connection, so that an operator can screw the screw 7 into the threaded hole 6 and a fixed part on a main shaft 3 to rotationally lock the main shaft 3;

an installation groove 9 is reserved on the side of the first groove 5, a second groove 10 is formed in one side, close to the threaded hole 6, of the interior of the installation groove 9, a bolt 11 is arranged in the second groove 10, an extrusion block 12 is adhered to the outer side of the bolt 11, one end, close to the second groove 10, of the bolt 11 is arranged in a bevel edge mode, and the bolt 11 and the second groove 10 form a relative sliding structure, so that an operator can insert the bolt 11 into the corresponding second groove 10 after screwing the screw 7;

the cross section of each extrusion block 12 is trapezoidal, and the extrusion blocks 12 are made of rubber, so that when an operator inserts the pins 11 into the corresponding second grooves 10, the extrusion blocks 12 and the screw rods 7 can be mutually extruded, the rotation of the screw rods 7 is further limited, and the situation that the screw rods 7 are easy to loosen due to vibration and other reasons is avoided;

the inside top of second recess 10 is reserved has through-hole 13, and the inside of through-hole 13 runs through has squeeze stem 14, the bottom of squeeze stem 14 is the arc setting, and squeeze stem 14 constitutes relative sliding structure with through-hole 13, when making operating personnel extrude bolt 11's hypotenuse in inserting corresponding through-hole 13 with squeeze stem 14, bolt 11 can slide and leave the inside of second recess 10, and then relieve the mutual extrusion of extrusion piece 12 and screw rod 7, make things convenient for operating personnel to relieve the locking.

The working principle is as follows: when the wind turbine generator wind wheel locking disc is used, the device is arranged on a generator part through the mounting ring 4, and is mutually rotationally connected with the main shaft 3, so that the main shaft 3 can normally rotate, when the main shaft 3 needs to be locked, the screw 7 is screwed into the threaded hole 6 until the screw 7 enters the fixing piece on the main shaft 3 through the threaded connection of the screw 7 and the threaded hole 6, so that the locking disc main body 1 and the fixing piece on the main shaft 3 are mutually fixed, so that the mounting ring 4 can lock and limit the rotation of the main shaft 3, and simultaneously, the bolt 11 is inserted into the second groove 10 through the sliding connection of the bolt 11 and the second groove 10 until the extrusion block 12 on the bolt 11 and the screw 7 are mutually extruded, so that the extrusion block 12 and the bolt 11 are fixed by pre-tightening force, and the rotation of the screw 7 is limited at the moment, therefore, the screw 7 is prevented from being loosened easily due to factors such as vibration and the like in the subsequent maintenance process;

when the screw 7 needs to be unscrewed again after the overhaul is completed, the prepared extrusion rod 14 is inserted into the through hole 13 at this time until the extrusion rod 14 extrudes the bevel edge at one end of the bolt 11 in the second groove 10, so that the bolt 11 can slide in the direction away from the second groove 10 until the extrusion block 12 and the screw 7 are released from mutual extrusion, the bolt 11 is taken out of the second groove 10 for collection, the extrusion rod 14 is taken out of the through hole 13 for collection, then the screw 7 is unscrewed from the fixed part on the main shaft 3 and the threaded hole 6 for unlocking, when the screw 7 is blocked in the screwing process, oil substances can be injected into the threaded hole 6 through the oil hole 8 by means of auxiliary tools such as an injector, the screw 7 is fully lubricated, and the situation is prevented from being rapidly processed by an operator.
