Description
Technical field
The invention belongs to the brake technique field, be specifically related to a kind of wind-driven generator mechanical braking device.
Background technique
Wind-driven generator is applied at present, when wind power generating set breaks down or safeguards, need the upper tower cylinder top to wind power generating set of staff, debug, overhaul and safeguard unit, for guaranteeing the safety of staff and equipment, wind-driven generator is stopped operating.For the direct-driving type wind power generation machine, blade pass is crossed wheel hub and directly is connected with generator, and generator is stopped operating need to very large moment.On the wind-driven generator, for making the blower fan mechanical braking, usual way is latch between the brake disc of fixing end cap and rotation.When brake disc hole and end cap upper bracket hole decentraction, common latch is difficult to insert, impossible and manually rotate brake disc, only have that to wait for that wind-force makes brake disc turn to the brake disc hole approaching to timing with end cap upper bracket hole, again attempt latch, this mode latch is difficult to one-time-reach-place, needs repeatedly to attempt, so lose time.The diameter of general latch is 100 millimeters magnitude, and the hundreds of millimeters of length weigh tens kilograms.Free-hand plug latch is quite required great effort, if tens of meters high-lift operation, it all is very difficult latch being blocked or extract, and undue force also easily causes the damage of wind-driven generator.
Summary of the invention
The object of the present invention is to provide a kind of wind-driven generator mechanical braking device, overcome former wind-driven generator machinery lock pin plug hard problem, making the operator only need to rotate corresponding part with spanner can easily insert lock pin and extract, and avoids firmly knocking and causes wind-driven generator to damage.
The technical solution of the utility model is: a kind of wind-driven generator mechanical braking device comprises round nut, lock pin, tie rod, ejector rod and packing ring.
Round nut is weldingly fixed on the motor rear end cap surface, and round nut is coaxial with Generator brake dish and support.
Described lock pin is the cylindrical cavity body structure, and inner cavity is cylindrical, and an end of lock pin is that free end and the outside are taper, and there is the trapezoidal thread hole at the other end center, and in the isoplanar one flange is arranged along this end outside, and flange is provided with through hole; During insertion: tie rod one end is inserted in packing ring and penetrates in the trapezoidal thread hole of lock pin and is threaded with round nut; When extracting: ejector rod one end cooperates with round nut, and the other end cooperates with lock pin trapezoidal thread hole.
One end of described tie rod is that section is " ten " shape part, a vertical end is threaded, this end is inserted in packing ring and penetrates in the trapezoidal thread hole of lock pin and is threaded with round nut, the other end is hexagon, and this end has through hole, by through hole link is arranged, vertically the diameter of bar is slightly less than the diameter in lock pin trapezoidal thread hole, the horizontal end diameter of bar is greater than the diameter in lock pin trapezoidal thread hole, and the assurance tie rod is vertically held and can be inserted in packing ring and the lock pin, and the horizontal end of bar is stuck in outside packing ring and the lock pin;
Described ejector rod is multidiameter shaft shape, thin segment is that polished rod and an end have the round boss with lead angle, the diameter of this round boss is slightly less than the round nut internal diameter, on the thick section trapezoidal thread is arranged, and cooperate with lock pin trapezoidal thread hole, one end of thick section has the hexagonal boss, and through hole is arranged on the boss, by through hole link is arranged.
The beneficial effects of the utility model: this braking device has adopted the forms of motion of slip screw transmission, realize that by the lock pin guiding with the cone end centering in brake disc hole and end cap upper bracket hole is concentric, the quick location that cooperates again tie rod and ejector rod, wind-driven generator is stopped operating, be convenient to staff's operation.
