Description
Technical field
The utility model relates to break, concrete is a kind of wind power generating set dynamo-electric brake.
Background technique
At present, in the wind-power electricity generation industry,, adopt hydraulic brake, the retardation pressure height of hydraulic brake, good braking effect to the design of booster engine break and off-course brake in the wind power generating set more.Yet in use there is oil leakage phenomenon in hydraulic brake, can cause environmental pollution, system down.Particularly wind power generating set is the equipment of a kind of unmanned guard, high dry running, and the cycle of equipment routing inspection is long, in case because of the leakage of oil problem causes brake system failure, will produce serious consequence.Though having invented dynamo-electric brake, someone replaces hydraulic brake, but this dynamo-electric brake also exists period of braking length, complex structure, big, the problems such as the special installing space of dynamo-electric brake needs, price height of going off course of volume, has limited the extensive use of dynamo-electric brake.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of wind power generating set dynamo-electric brake at the problems referred to above, and period of braking length, complex structure, the volume of the wind power generating set dynamo-electric brake existence before solving is big, the driftage dynamo-electric brake needs problems such as special installing space, price height.
The utility model is achieved through the following technical solutions: a kind of wind power generating set dynamo-electric brake, comprise motor, retarder, support body, coupling, power screw pair, interlock resetting-mechanism, thrust-bearing, load cell, down brake jaw, brake disc, on brake the controller of jaw and wind power generating set; The input end of motor and retarder is connected, retarder is fixedlyed connected with support body, the output terminal of retarder connects leading screw, thrust-bearing, the load cell in coupling, the power screw pair successively and brakes jaw down, and the nut in the power screw pair is fixedlyed connected with support body; Wherein, the electric output terminal of the electrical input of motor and the controller of wind power generating set is connected, and the electrical input of the electric output terminal of load cell and the controller of wind power generating set is connected; Under brake jaw and last braking jaw lays respectively at the brake disc both sides, following braking jaw is connected with last braking jaw by the interlock resetting-mechanism.
Adopt the good effect of technique scheme: the utility model advances with the leading screw in the motoring power screw pair or retreats, on driving, under brake jaw brake disc braked, and between leading screw and following braking jaw, install load cell additional, the electric output terminal of load cell is connected with the electrical input of the controller of wind power generating set, because load cell can change into electrical signal with pressure signal, after the controller of wind power generating set receives the signal that load cell sends, send instruction by analysis and give the motor that is connected with its electric output terminal, the rotating speed of control motor, turn to and motor reel braked, thus drive go up the braking jaw and down the braking jaw in carrying out braking process, implement F.F., the worker advances, rewind down, stop and to the locking or the brake off of braking force; Since load cell sensed pressure sensitivity, the measuring accuracy height, the controller of wind power generating set can change control state of motor automatically according to load cell institute sensed pressure, makes that the braking needed time is short, and retardation pressure is able to accurate control; Because the axis of the axis of motor, reducer output shaft is identical with the axial direction of upper and lower braking jaw, make this dynamo-electric brake simple in structure, volume is little, the dynamo-electric brake of going off course does not need special installing space, price is low.
