Specific embodiment
The operating power of elevator is provided by motor.Under control of the controller, motor drives reductor, then
Band moving gear realizes the corresponding elevating movement of lift car.Elevator of the present invention is segmented speed limiting protector,
As shown in figure 1, including runner 3, friction mandrel 4, friction drag unit and ratchet drag unit, it is described
Runner 3 is fixed and is set on friction mandrel 4, and two radial slots 34 are provided with symmetrically along radial direction on runner 3.
Friction drag unit is used for the speed-limiting protection of first stage after elevator overspeed, as shown in Figure 2,3,
The friction drag unit has two, including centrifugal-block 31, connecting rope 32 and friction plate 33, centrifugal-block
31 and friction plate 33 connected by connecting rope 32,32 sets of the connecting rope is through on friction mandrel 4, from
Heart block 31 is slidably disposed within radial slot 34；
Ratchet drag unit is used for the speed-limiting protection of second stage after elevator overspeed, as shown in Figure 4,5,
The ratchet drag unit includes ratchet 5, ratchet 6 and oil cylinder 7, and ratchet 5 is fixed and is set in friction mandrel 4
On, the ratchet 6 and the piston rod of oil cylinder 7 matched with ratchet 5 are hinged by ratchet-oil cylinder jointed shaft 9；
Runner 3, friction drag unit and ratchet 5 have been sequentially distributed on the friction mandrel 4 vertically.
The elevator segmentation speed limiting protector is also included for the controller of control cylinder action and for examining
The tachogenerator of the rotating speed of friction mandrel 4 is surveyed, tachogenerator and controller are electrically connected.
When elevator of the present invention segmentation speed limiting protector is installed, by shaft coupling 2 by line shaft 1 with rub
Wipe axle 4 to connect, then runner 3 and ratchet 5 are fixed be set on friction mandrel 4, so, elevator it is dynamic
Power axle 1, friction mandrel 4, runner 3 and ratchet 5 are just combined as a whole, and are rotated according to same rotational speed.
This elevator segmentation speed limiting protector course of work is as follows：
When elevator normally runs, in friction drag unit, suffered by the centrifugal-block 31 being placed in radial slot 34
Centrifugal force is insufficient to allow the friction plate 33 being connected with centrifugal-block 31 to be in close contact with friction mandrel 4, does not influence
The rotating speed of friction mandrel 4, therefore friction drag unit does not interfere with the speed of service of elevator in this case；Together
In sample ratchet drag unit, oil cylinder 7 does not work, when the ratchet 5 that fixation is set on friction mandrel 4 is rotated,
Ratchet 6 is streaked in hook tooth back, and the rotating speed of ratchet 1, therefore ratchet drag unit are not influenceed in this state
Under do not interfere with the speed of service of elevator yet.
When elevator rotating speed exceedes allows rotating speed, according to being pre-designed, friction drag unit is started working,
Now two centrifugal-blocks 31 are under the influence of centrifugal force in respective radial slot 34, to away from runner
The one end in the center of circle is slided, and connecting rope 32 is tightened so that two panels friction plate 33 closely connects with friction mandrel 4
Touch, the rotating speed of friction mandrel 4 is declined by the frictional force between them, and then so that under the rotating speed of line shaft 1
Drop；When the drag unit that rubs works so that the rotating speed of line shaft 1 drops to default initiation value, ratchet retardance
Unit is started working, and controller control cylinder 7 is acted, cylinder piston rod jack-up, the ratchet being hinged therewith
6 are gradually rotated upwards around ratchet jointed shaft 8, and ratchet 6 is just gradually stretched into ratchet teeth groove so that ratchet
It is restricted with the rotation of friction mandrel 4, the rotating speed of friction mandrel 4 is gradually reduced up to stopping, at this moment, power
Axle 1 also stopped rotation, so that lift car also stop motion.After failture evacuation, then by control
The piston rod of device control cylinder 7 processed withdraws, and elevator just can continue normal work.
It is pointed out that only receive tachogenerator in the ban for the controller that control cylinder is acted adopting
After the tachometer value more than permission rotating speed for collecting, then receive the default initiation value that tachogenerator is collected
When, just meeting control cylinder 7 is acted.
The afterbody of the ratchet 6 is hinged by ratchet jointed shaft 8 with support bar 10.
During in order to ensure that this limiter of speed works, friction plate 33 is preferably contacted between friction mandrel 4,
The friction plate 33 is designed as arc-shaped flaky structure.
When normally being run to reduce elevator, influence of this limiter of speed to elevator speed, the connecting rope 32
It is elastic threads.
Section Example of the invention has been described in detail above, but the content is only of the invention
Preferred embodiment, it is impossible to be considered as limiting practical range of the invention.It is all according to the present patent application scope
The impartial change made and improvement etc., all should still belong within patent covering scope of the invention.
