Abstract
The invention discloses a construction lifter motor with a centrifugal braking device, comprising a motor output shaft and an electromagnet braking device. The motor output shaft is connected with a swivel plate, a centrifugal friction ring is arranged at the outer peripheral face of the swivel plate, and a motor bracket which can be in contact with the centrifugal friction ring when the motor is at a high-speed state is arranged at the outer peripheral face of the centrifugal friction ring. The invention has reasonable structure, and when the electromagnet braking part fails, the centrifugal friction ring is in contact with the motor bracket due to the high-speed running of the motor under the centrifugal force to generate friction with the motor bracket so as to ensure that a construction lifter slides downwards slowly.
Description
Technical field
The present invention 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 is prone to cause the accident.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructurely, when the electromagnet brake portion breaks down, guarantee the construction lifter motor of the band centrifugal braking device of building hoist slip.
Technical solution of the present invention 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.Said 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 and is sleeved on the nut on the screw rod, on the screw rod at position, nut outer end split pin is set.
Rotating disk is connected through key with motor output shaft.
Said motor fast state, the state when being meant motor speed greater than 1400 rev/mins; State when said building hoist high speed slip-down state is meant the building hoist gliding speed greater than 1.1m/s.
The present invention 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.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the structural representation of friction-type centrifugal hoop.
