Description
Technical field
The present invention relates to elevator safety equipment technology fields, in particular to a kind of to realize that elevator is anti-by gas backwash mode
The device and method to fall.
Background technique
With the development of urban population centralization trend, skyscraper cumulative year after year in city, the use of elevator becomes
Especially extensively.Elevator safety is increasingly becoming the problem of people's growing interest, especially VTOL elevator, once breaking down
There is the danger fallen, passenger not only physically will receive serious life threat in elevator, but also still suffer from huge
Psychological burden.
Currently, have numerous device for preventing elevator from falling to fall when preventing elevator faults, but these falling proof devices are also
There are many disadvantages and limitation.Such as 1: the shape of elevator fall arrest is realized using previous elevator governor and rope brake
Formula, disadvantage: when elevator needs the speed centainly to drop, limiter of speed can just work with rope device is held under the arm, fall thing in lowrise layer
Used during elevator falling is not can avoid in therefore.Such as 2: the shape of elevator fall arrest is realized using the motor-driven safeties such as previous electric control lock lock
Formula, disadvantage: for elevator when unexpected have a power failure, electric control lock is easy failure under outage condition, not can guarantee used during elevator falling lock
Dead elevator prevents from dropping.There is also certain drawbacks for current device for preventing elevator from falling as a result, and anti-fall without other new elevators
Dropping control device is alternative.
Disadvantages mentioned above affect to a certain extent elevator using safe, in order to solve the above problem, this patent application
Compressed gas sprays the principle that the reaction force to be formed realizes the slow drop of deceleration during elevator tenesmus, proposes a kind of gas backwash
Slow drop device for preventing elevator from falling and method are, it can be achieved that elevator slows down slow drop protection elevator ride personnel's during failing tenesmus
Security function.
Summary of the invention
The purpose of this patent is directed to the drawbacks of existing device for preventing elevator from falling, and it is anti-fall to provide a kind of slow drop elevator of gas backwash
Dropping control device and method.
In order to solve the above-mentioned technical problem used technical solution is this patent:
During elevator drops suddenly, tenesmus signal is transmitted to gas backwash injector, gas by falling velocity sensor
Injector recoil according to the speed of used during elevator falling automatic adjustment gas spout size, the compressed gas of liquid gas storage column passes through
Gas backwash injector controls to adjust, and the back flushing gas for spraying some strength is the deceleration of elevator that falls, and gas backwash injector is certainly
The dynamic spout realization elevator that falls that adjusts remains a constant speed safe decrease speed, to elevator terrain clearance sensor test to elevator from
When ground certain distance, triggering gas backwash injector automatically adjusts jet size, increases injection gas intensity, subtracts for tenesmus elevator
Speed, when elevator reaches ground location, deceleration of elevator to stopping, elevator terrain clearance sensor test to elevator ground clearance
When being zero, triggering gas backwash injector closes gas injection.
Patent provides a kind of slow drop device for preventing elevator from falling of gas backwash:
The dedicated unit is applied to the fall arrest under elevator emergency state comprising with lower component: elevator structure frame, speed of falling
Sensor, elevator terrain clearance sensor are spent, liquid gas stores column, gas backwash injector；It is characterized in that speed biography of falling
Sensor is mounted on elevator structure frame, and elevator terrain clearance sensor is mounted on elevator structure frame, liquid gas storage
Column is mounted under elevator structure framework bottom, and gas backwash injector is mounted below liquid gas storage column.
In the present apparatus, nontoxic liquid pressurized gas is laid in liquid gas storage column, it is gas that liquid gas, which stores column,
Body recoil injector provides gas；Tenesmus signal is transmitted to gas backwash injector by the velocity sensor that falls, gas backwash injection
Device can automatically adjust gas spout size according to the speed of used during elevator falling；Gas backwash injector automatic adjustment spout can realize pendant
Elevator is fallen to remain a constant speed safe decrease speed；When elevator terrain clearance sensor tests certain distance liftoff to elevator, touching
Signalling passes to gas backwash injector；Gas backwash injector is adjusted according to the altitude signal of elevator terrain clearance sensor
Increase injection gas intensity；Elevator terrain clearance sensor test to elevator ground clearance be zero when, triggering gas backwash injection
Device closes gas injection.
This patent has the advantages that
1, a kind of slow drop device for preventing elevator from falling of gas backwash and method are provided, is provided newly for elevator anti-falling safe technology
Method and new way.
2, the use of this device for preventing elevator from falling and method can effectively avoid the generation of elevator tenesmus accident, significantly mention
Security reliability in high elevator use process.
3, this patent facilitates the development and application that the following elevator puts free fall technique, has in elevator safety devices technical field
Have wide practical use.
4, compact-sized, implementation is simply.
Detailed description of the invention:
The slow drop device for preventing elevator from falling scheme of installation of Fig. 1, gas backwash
In figure: 1 elevator structure frame, 2 fall velocity sensor, 3 elevator terrain clearance sensors, and 4 liquid gases store column, and 5
Gas backwash injector
Specific embodiment:
1 pair of specific implementation of the patent scheme is illustrated with reference to the accompanying drawing.
Scheme is as follows: during elevator drops suddenly, it is anti-to be transmitted to gas by falling velocity sensor 2 tenesmus signal
Injector 5 is rushed, gas backwash injector 5 automatically adjusts gas spout size, liquid gas storage according to the speed of used during elevator falling
The compressed gas of column 4 is controlled to adjust by gas backwash injector 5, is sprayed the back flushing gas of some strength and is subtracted for the elevator that falls
Speed, gas backwash injector 5 automatically adjusts the spout realization elevator that falls and remains a constant speed safe decrease speed, to the liftoff height of elevator
When degree sensor survey 3 tries certain distance liftoff to elevator, gas is sprayed in the triggering automatic adjustment spout of gas backwash injector 5, increase
Body intensity, for the deceleration of elevator that drops, when elevator reaches ground location, deceleration of elevator to stopping, elevator terrain clearance is sensed
Device 3 test to elevator ground clearance be zero when, triggering gas backwash injector 5 closing gas injection, it can be achieved that used during elevator falling mistake
The function that journey deceleration is slowly landed.
The slow drop device for preventing elevator from falling of this gas backwash and method are conducive to avoid the generation of used during elevator falling accident, significantly
The security reliability in elevator use process is improved, before this patent has a wide range of applications elevator safety devices technical field
Scape.
