Description
Technical field
The invention belongs to the Complete engineering techniques field of elevator device；Centrifugal governor especially suitable for track elevator
Subsidiary engine corollary apparatus.
Background technique
Now, skyscraper is higher and higher, and elevator has become essential corollary equipment.Rail mounted Wheelchair Accessible by
In can the obstacle free safety even running under power failure or fire condition, obtain the approval in market；Because of the carriage of the elevator device
It is to hold rack-track tightly to go the rounds up and down, changes the operating idea of traction elevator system, thus track elevator governor completely
It comes into being；Track elevator governor is divided into centrifugal mechanical adjustment and slows down and electromagnetic type brake holding deceleration, for centrifugal mechanical
The design of slowdown type limiter of speed is merged, centrifugation wheel assembly is be unable to do without, therefore designs sensitive stable centrifugation wheel assembly and especially must
It wants.
Summary of the invention
Needed for above, this flyball formula track elevator governor centrifugation wheel assembly is specially designed.
Solution of the invention is: flyball formula track elevator governor is centrifuged wheel assembly, including flyball, axial pulley,
Movable friction plate, return spring, spacer ferrule；It is characterized in that: axial pulley is assembled on the speed limit axis of track elevator centrifugal speed limiter,
Axial pulley can slide axially along speed limit axis；Movable friction plate is assembled in axial pulley side, with track elevator centrifugal speed limiter
On determine that friction plate is corresponding, and the other side symmetrically reserves multiple flyball pilot holes, assembles flyball on flyball pilot hole；In flyball side
Speed limit axis on stationary positioned hoop, connect multiple return springs between spacer ferrule and axial pulley.
As described above, flyball is made of tup and hammer stem, hammer stem one end fixed hammer, the other end reserves pintle and connection
Hole；Connecting hole is combined with the flyball pilot hole matching of axial pulley.
As described above, movable friction plate has relief with friction plate is determined under speed limit axis stationary state；Flyball is in return spring
Under pulling force effect, it is attached on spacer ferrule；When the rotation of speed limit axis, the tup of flyball leaves spacer ferrule under the influence of centrifugal force
It shifts outward, the pintle on hammer stem will stir axial pulley to the movement of friction plate side is determined, and so as to cause movable friction plate and determine
Friction plate adjustment generates frictional force, so that the speed limit axis of rotation is slowed down by resistance, achievees the effect that speed limit.
The advantageous effect of the invention is: the invention can effectively control the operating of speed limit axis on track elevator centrifugal speed limiter
Speed limits its overspeed, and lift car is avoided to generate secondary disaster because of overspeed.
Detailed description of the invention
The invention is further illustrated with reference to the accompanying drawing.
Attached drawing 1 is the structural schematic diagram of the invention.
The axial 21 flyball pilot hole 3 of pulley of 1 flyball, 11 tup, 12 pintle, 13 connecting hole 2 is dynamic in figure rubs
4 return spring of pad, 5 spacer ferrule, 6 speed limit axis 7 determines friction plate.
