The braking shell 3 is rotatably connected, and the braking connecting rod 6 is rotatably connected with the keep plate 5, the bidirectional speed limiter
Connected between 2 and the keep plate 5 by steel wire rope；
The braking connecting rod 6 is located at the both sides of the lift car 1, and it includes up brake bar 61 and descending brake bar 62,
The relative tilt of up brake bar 61 is set, the spacing between the up brake bar 61 of the both sides of lift car 1 from
Under gradually increase to upper；
The relative tilt of descending brake bar 62 is set, between the descending brake bar 62 of the both sides of lift car 1 between
Away from gradually increasing from top to bottom.
The lift car 1 is used to load people or goods etc., and it includes railway carriage or compartment door and is arranged inside the lift car
Danger button, the danger button is connected with the drive device of elevator, directly acts on the drive device, works as emergency
During appearance, the danger button directly pressed on the door of railway carriage or compartment can stop the driving of drive device, it is ensured that when emergency occurs, people
Can be robbed in the very first time by danger button, stop the operation of elevator, when preventing elevator overspeed, drive device still acts on institute
Lift car is stated, increases the braking difficulty of brake apparatus.
The bidirectional speed limiter 2 is used for when elevator overspeed is travelled, and acts on the keep plate 5 so that the keep plate 5
It is out of service, relative slip then is formed between the keep plate 5 and the braking shell 3, so as to compress the braking connection
Bar 6, realizes the braking of the lift car 1, and the concrete structure for the bidirectional speed limiter 2 that the present invention is provided is conventional for this area
Technical characteristic, here is omitted.
The braking shell 3 is in integrative-structure, is arranged at around the lift car 1, surrounds the lift car 1
Four faces, four faces surrounded by the braking shell 3 are respectively the upper and lower surfaces of lift car 1 and are provided with keep plate
5 two faces, wherein, being provided with two faces of keep plate 5 is used to coordinate the grade of keep plate 5 brake apparatus, realizes the system
The braking of dynamic shell 3, because the braking shell 3 is that, in integrative-structure, therefore after the braking shell 3 is braked, position is in the inner
The lift car 1 in portion also follows the braking stop motion of shell 3.
The braking column 4 is located at the both sides of the lift car 1, for connecting with the braking shell 3 and the braking
Extension bar 6 cooperates, and realizes braking effect, because the braking column 4 is main stressed member when braking, therefore the braking
Column 4 is made up of the material of high intensity and high tenacity, when preventing braking, and the bending of braking column 4 is so that braking can not be realized
Effect.
Further, the inwall that the braking column 4 is close to elevator hoistways is set, and is prevented that indicating brake action is excessive, is caused institute
The braking deformation of column 4 is stated, herein by the braking column 4 and elevator hoistways design bonded to each other, the braking column 4 is prevented
Expanded outwardly in braking, so as to influence its braking effect.
More preferably, the braking column 4 is additionally provided with anti-skid structure with the face that the keep plate 5 is in contact, and prevents braking
When, the keep plate 5 produces relative slip with the braking column 4, influences its braking effect.
The keep plate 5 is in contact with the braking column 4, and it is connected with the bidirectional speed limiter 2 by steel wire rope,
When elevator is run, contact with each other but do not stress between the keep plate 5 and the braking column 4, the keep plate 5 is described double
To in the presence of limiter of speed 2, the lift car 1 is followed to move up and down, and the fortune of the keep plate 5 and the lift car 1
Dynamic direction is identical, and speed is equal, during braking, the stop motion of bidirectional speed limiter 2, it is connected with the bidirectional speed limiter 2
The stop motion of keep plate 5, the keep plate 5 produces relative slip with the braking shell 3, extrudes the braking connecting rod
6, so as to realize braking.
Further, the keep plate 5 is additionally provided with coarse structure with the face that the braking column 4 is in contact, for increasing
Plus the frictional force between the keep plate 5 and the braking column 4, prevent that the keep plate 5 from sliding relatively with the braking column 4
It is dynamic, influence its braking effect.
The braking connecting rod 6 is used to connect the braking shell 3 and the keep plate 5, the braking connecting rod 6 and institute
State braking shell 3 between be rotatably connected, and it is described braking connecting rod 6 be rotatably connected with the keep plate 5, it is described braking company
The setting substantially symmetrical about its central axis of the relatively described lift car 1 of extension bar 6, positioned at the both sides of the lift car 1, it includes described up
Brake bar 61 and descending brake bar 62, the up relative tilt of brake bar 61 are set, in " eight " font, positioned at the elevator
Spacing between the up brake bar 61 of the both sides of car 1 gradually increases from top to bottom；The relative tilt of descending brake bar 62 is set
Put, in " eight " font, the spacing between the descending brake bar 62 of the both sides of lift car 1 gradually increases from top to bottom.
The elevator with bidirectional speed limiter that the present invention is provided, when the 1 up hypervelocity of lift car, the two-way limit
The fast stop motion of device 2, the lift car 1 continues up, therefore the relatively described keep plate 5 of the braking shell 3 is moved upwards, even
The up connecting rod 61 for connecing the keep plate 5 and the braking shell 3 produces rotation, and the up connecting rod 61 is compressed,
Micro- deformation is produced, during, the descending connecting rod 62 does not stress, and the keep plate 5 and the braking relative motion of shell 3
Distance it is bigger, the up connecting rod 61 is bigger by compression degree, thus the keep plate 5 and it is described braking column 4 between
Frictional force it is bigger, so as to realize the up speed limit of the elevator with bidirectional speed limiter.
When 1 overspeed descending of lift car, the descending connecting rod 62 produces micro- deformation and compressed, the up company
Extension bar 61 does not stress, so as to realize the descending speed limit of the elevator with bidirectional speed limiter.
Herein it should be noted that the bidirectional speed limiter that provides of the present invention, using the keep plate 5 and the braking column
Frictional force between 4 realizes braking, when emergency occurs, it is ensured that on the premise of the boarding safety of boarding personnel, can be with
The parts, relatively conventional brake structure, braking such as realization is used for multiple times and does not damage braking shell 3, braking column 4, keep plate 5
Maintenance cost is low afterwards.
