Abstract
The utility model discloses a construction lifter motor with a centrifugal brake device, comprising a motor output shaft and an electromagnet brake device. The motor output shaft is connected with a rotary table, a centrifugal friction ring is installed at the outer circumferential surface of the rotary table, and the periphery of the centrifugal friction ring is arranged at the position of a motor bracket which is abraded and connected with the centrifugal friction ring under the high-speed state of a motor. In the utility model, the structure is reasonable, when an electromagnet brake part is in failure, the centrifugal friction ring is contacted with the motor bracket due to the centrifugal force caused by the high-speed running of the motor, thus generating friction, and ensuring the slow gliding of a lifter for construction.
Description
Technical field
The utility model relates to a kind of construction lifter motor.
Background technology
When existing building hoist broke down at the electromagnet brake portion, lift can quicken suddenly to glide, and easily causes the accident.
The utility model content
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and when the electromagnet brake portion breaks down, guarantees the construction lifter motor of the band centrifugal braking device of building hoist slip.
Technical solution of the present utility model is:
A kind of construction lifter motor with centrifugal braking device, comprise motor output shaft, the electromagnet brake apparatus, it is characterized in that: motor output shaft is connected with rotating disk, dress centrifugal friction ring on the rotating disk outer peripheral face, centrifugal friction ring periphery be arranged under the motor fast state or under the building hoist high speed slip-down state can with the electric machine support of centrifugal friction ring CONTACT WITH FRICTION.
Each one, symmetrically arranged form about the centrifugal friction ring is.Described centrifugal friction ring is connected with the screw rod that passes rotating disk, stretches out an end pocketed springs of rotating disk at screw rod, and the spring outer end is provided with the nut that is sleeved on the screw rod, on the screw rod at position, nut outer end split pin is set.
Rotating disk is connected by key with motor output shaft.
Described motor fast state, the state when being meant motor speed greater than 1400 rev/mins; State when described building hoist high speed slip-down state is meant the building hoist gliding speed greater than 1.1m/s.
The utility model is rational in infrastructure, and when the electromagnet brake portion broke down, running up of motor made the centrifugal friction ring under centrifugal action, contacts with electric machine support, produces friction, guarantees the building hoist slip.
