No. three springs are set in cylinder, and No. three springs push up piston upwards, and piston and cylinder internal memory be in gas, when lift car falls
When, upward thrust can be produced by the gas in extrusion piston and cylinder, and when gas is compressed, it is slow so as to be played to car
The effect of punching, buffering of the spring to car is instead of, avoids the violent bounce-back by spring, be used to not only slower elevators,
The elevator of speed is also used in, improves the scope of application；And burst bullet when the gas in piston and cylinder is compressed to
Property barrier film after, gas enters elastic bag by tracheae, and elastic bag is stretched, to car produce similar to air bag effect
Fruit, by being buffered again by elastic bag after the buffering of cylinder when enabling the lift car fall, by double buffering, greatly
The big security for improving buffer, security are good.In addition, it is of the invention also by being provided with reflectorized material on track roller,
Reflectorized material is driven to roll therewith when track roller rolls, and the laser signal that reflectorized material sends generating laser is delivered to
On laser pickoff, signal is passed to signal processor by laser pickoff again by calculating the speed of track roller,
Improve the sensitivity of mechanism；By setting gear in rack case, and gear and motor connection, motor driven gear are counterclockwise
Rotation, rack is moved to the left after gear drives again, and rack moves right before drive, so as to drive the push rod in bearing to push away forward,
The effect of elevator brake car is played, mechanical flexibility is good；By being provided with multiple equally distributed cards on the push rod in bearing
Block, and bearing inwall is provided with multiple equally distributed necks, neck and the position of fixture block are mutually corresponding, when push rod pushes away forward

Operation principle：When lift car 1 falls because of certain reason, lift car 1 is not controlled by drag device,
It is changed into accelerating from original at the uniform velocity movement, so as to drive the track roller 2 on lift car 1 also to accelerate movement downwards, and
Track roller 2 is fixedly connected on lift car 1 through the first fix bar 13, and track roller 2 can be in the first fix bar 13
Swingle 14 rotate, the rolling friction of track roller 2 and guide rail 3 is driven when lift car 1 moves downward, so as to band
Dynamic track roller 2 rotates around swingle 14, and it is that speed is faster that lift car 1, which falls, then the rotary speed of track roller 2
It is faster；And reflectorized material 15 is connected with track roller 2 on outer ring, track roller 2 often rotates a circle, and drives reflectorized material 15
Rotate a circle, and the rotated reflectorized material 15 to during relevant position of the laser that generating laser 11 is sent is connect after reflecting by laser
Receive device 12 to receive, laser often reflects once, corresponding pulse signal is obtained on laser pickoff 12, and pulse signal is sent into and believed
Handled on number processor 6, signal processor 6 can measure the speed of the rotation of track roller 2, so as to measure lift car 1
Speed when falling, and tachogenerator 5 is equipped with each track roller 2, even if a tachogenerator 5 fails
When, another tachogenerator 5 can also pass to signal signal processor 6, play a part of double insurance.
When speed when lift car 1 falls is more than a boundary value, the controlled motor 7 of signal processor 6 starts, motor
7 start rotate counterclockwise, drive the rotate counterclockwise of gear 16 in rack case 8, rack after the rotate counterclockwise drive of gear 16
18 are moved to the left, and rack 17 moves right before drive, and then rack 18, which is moved to the left, drives the push rod 19 in left side to push away forward, push rod
Push rod 10 in 19 drive bearings 9 pushes away forward, and push rod 10 is provided with multiple equally distributed grooves 20, when push rod 10 pushes away forward
Fixture block 22 is compressed, fixture block 22 makes No.1 spring 21 toward the contract of groove 20, and the inwall of bearing 9 is provided with multiple equally distributed cards
Groove 23, neck 23 and the position of fixture block 22 are mutually corresponding, and when push rod 10 pushes away forward, the fixture block 22 on push rod is stuck on bearing 9
Neck 23 in, push rod 10 is not easy toward rollback, so as to be stuck in bearing 9；The one end of push rod 10 is driven when push rod 10 pushes away forward
Wedge type block forward, until withstanding rail clamp plate 4, now No. two both ends of spring 25 on wedge type block 27 are compressed in No.1 groove respectively
24 and No. two grooves 26 in, and the elastic force of No. two springs 25 makes wedge type block 27 be contacted all the time with rail clamp plate 4, and wedge type block 27 is additionally provided with
Multiple equally distributed salient points 28, further increase the frictional force between wedge type block 27 and rail clamp plate 4, and limited block 30 is spacing
Bottom position of the wedge type block 27 relative to push rod 10, when lift car 1 falls downwards, frictional force makes the wedge type block 27 upward
It is mobile, and wedge type block 27 is up-narrow and down-wide design, wedge type block 27 is so as to be stuck between rail clamp plate 4 and push rod 10, and elevator
The bottom of car 1 is provided with multiple bearings 9, and each bearing 9 is fixed on the bottom of lift car 1 by the first fixed block 29, and often
Push rod 10 is cased with individual bearing 9, each one end of push rod 10 is respectively connected with wedge type block 27, and in multiple wedge type blocks 27 and push rod 10
In the presence of until making lift car 1 stop in rail clamp plate 4, protect the safety of personnel in lift car 1.
In the presence of multiple wedge type blocks 27 and push rod 10 lift car 1 can not stop in rail clamp plate 4, make elevator car
When railway carriage or compartment 1 is fallen to pit, first touch on the elastic layer 47 in buffer unit 48, elastic layer 47 plays to lift car 1 first
Buffering be effect, when lift car 1 downwards fall move down elastic layer 47 and piston 33 when, piston 33 is because by No. three
The upward effect of spring 32, filled with gas in piston 33 and cylinder 31, the gas in the extrusion piston 33 of lift car 1 and cylinder 31
During body, gas compressed can produce upward thrust to piston 33, so that piston 33 plays the work of buffering to lift car 1
With；When lift car 1 is too big to impact caused by piston 33, gas compressed in piston 33 and cylinder 31 is set to produce more
Big active force, the elastic diaphragm 36 of the one end of tracheae 35 is burst, and then make the gas of compression through being connected to the bottom gas of cylinder 31
Tracheae 35 on hole 34 is transported at valve 37, and the spill spin block 39 for making to connect on valve 37 is fixed in the presence of gas around second
Bar 40 is left on, and is entered in space of the gas between valve 37 and tracheae 35 in elastic bag 38, and in elastic bag 38
The gas of original certain volume, when gas compressed enters in elastic bag 38 in piston 33 and cylinder 31, elastic bag
38 is big by further support, and until that can contact car, cushioning effect is played to car；And gas enters elasticity after strutting valve 37
Air bag 38, No. four springs 42 being fixed on valve 37 are retracted, and produce the pulling force to valve 37, and No. four one end of spring 42 are consolidated
It is scheduled in fixed seat 43, so that valve 37 resets, valve 37 is closed, and the sealant 44 on valve 37 further prevents
Overflowed outside into the gas in elastic bag 38, elastic bag 38 produces the effect similar to air bag to car, makes electricity
Terraced car 1 when falling can by after the buffering of cylinder 31 again by the buffering of elastic bag 38, and four of elevator pit
Edge is mounted on a cylinder 31, and each equal transtracheal 35 of cylinder 31 is connected with elastic bag 38, and elastic bag 38 is set
At the middle part of pit, enable lift car 1 when falling uniformly by the cushioning effect of four cylinders 31, car stress is more
Uniformly, the safety protective effect of the present invention is further increased.
And after 48 use of buffer unit, because the elastic diaphragm 36 in buffer unit 48 has been bursting at the collision, when need change bullet
During property barrier film 36, the collar 45 that spiral is connected to the one end of tracheae 35 can be backed out, good elastic diaphragm 36 is changed on tracheae 35,
The collar 45 is tightened again, good elastic diaphragm 36 is fixed on tracheae 35, and because the collar 45 is provided with perforate 46, thus the collar 45 is simultaneously
The use of elastic diaphragm 36 is not influenceed.
