Elevator uses dynamo-electric friction-type normally closed brake, so-called normally closed brake, refers to machinery not work
Brake when making, declutches during machine operation.During elevator brake, rely on the effect of mechanical force, make braking
Band with braked wheel friction and produce braking moment；When elevator runs, electromagnetic force is relied on to make brake declutch, because of
This is also known as electromagnetic brake.Produce the coil working electric current of electromagnetic force according to brake, be divided into alternating electromagnetic system
Dynamic device and DC electromagnetic brake.Due to DC electromagnetic brake braking steadily, volume is little, reliable operation,
Elevator many employings DC electromagnetic brake.The full name of the most this brake is normally closed type DC electromagnetic brake.
Brake is to ensure that the basic device of elevator safety operation, existing elevator brake have the disadvantage in that
1): enough braking moments cannot be produced, during braking, the axle of hoisting motor and the worm shaft of reduction box are produced
Raw additional load；2): when brake is declutched or brakes, poor stability, it is impossible to meet frequent starting and braking
Job requirement；3): brake should have enough rigidity and intensity difference, easily causes damage, need to change
And maintenance, more cost；4): easily produce high heat and high friction during braking, shorten the life-span, it is easy to deformation,
Noise is big, and noise is little.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, it is provided that a kind of with
Higher wearability and thermostability, simple in construction, be compact, easy to adjust, artificial brake-releasing gear, noise is little
Elevator brake.
This utility model solves its technical problem and be the technical scheme is that a kind of elevator brake, tool
Have magnetic apparatus base, the magnetic apparatus being arranged on described magnetic apparatus base, the two ends of magnetic apparatus be respectively connected with a left side,
Right brake arm, is provided with brake between left and right brake arm；
The top of described magnetic apparatus is provided with commutation controller, be provided with at intermediate position aroused in interest axle and through left,
Right brake arm, the side wall lower ends of magnetic apparatus is provided with rotating shaft, and rotating shaft is respectively at being located on left and right brake arm
Tripping spring seat connects and passes through the fixing locking of tripping spring adjusting nut, in the inner chamber of described tripping spring seat
Being provided with the tripping spring being set in rotating shaft, its outer surface is provided with braking moment synopsis.
Further, described brake scotch is provided with abrasion monitoring switch.
Further, described left and right brake arm is provided with the system installed by brake scotch axle and holding screw
Dynamic watt, brake scotch is located between brake and left and right brake arm, is provided with friction between brake and brake scotch
Sheet.
Further, the middle position of described magnetic apparatus is provided with the handle that declutches, and its sidewall upper is provided with pine
Lock instruction switch.
Further, the bottom of described left and right brake arm is provided with and is fixedly mounted by split pin and adjusting pad
Brake arm wheel.
The beneficial effects of the utility model are: this utility model can produce enough braking moments, and brakes
Moment size turns to unrelated with traction machine；During braking, the axle of hoisting motor and the worm shaft of reduction box are not produced
Raw additional load, operates steadily, and can meet the job requirement of frequent starting and braking, have enough rigidity
And intensity, simultaneous with higher wearability and thermostability, simple in construction, it is compact, easy to adjust, manually
Brake-releasing gear, noise is little.
