Anti-fall elevator is that stall sensing device and anti-fall device are mounted on elevator, and a general elevator is only equipped with a set of anti-fall dress
It sets, and stall induction trigger device mostly uses electric induction type, vulnerable to environmental disturbances, there are larger security risks, in anti-fall dress
It sets when not in time or just blocking because responding, it is easy to accident occur.
Summary of the invention
The purpose of the present invention is to provide a kind of segmented elevator anti-fall devices, with the reliable of hoisting elevator anti-drop system
Property.
For achieving the above object, technical scheme is as follows:
A kind of segmented elevator anti-drop system, including elevator, guide rail and elevator, which is characterized in that elevator, elevator well
Several groups brake unit is installed, brake unit component is sequentially arranged in elevator borehole wall from top to bottom, system on wall or guide rail
Moving cell includes accelerograph, elevator brake and controller assemblies, and accelerograph and elevator brake are solid respectively
It is scheduled on elevator borehole wall or guide rail, the output end of accelerograph is connected with the input terminal of controller, the output of controller
End is connected with elevator brake；The elevator acceleration information detected is passed to control by the accelerograph in brake unit
Device, controller judge acceleration value, when acceleration value is greater than predetermined value, controller start each group elevator brake into
Row emergency braking.
Technical solution as a further improvement of that present invention, the accelerograph are laser accelerometer.
Technical solution as a further improvement of that present invention, there are also alarm device, the controllers on the brake unit
Output end be connected with the input terminal of alarm device, when the controller start the elevator brake when, alarm device is same
Shi Qidong.
Technical solution as a further improvement of that present invention, the bottom of the elevator also have anti-fall well.
Technical solution as a further improvement of that present invention also has stall induction trigger device on the elevator.
Compared with prior art, beneficial effects of the present invention:
A kind of segmented elevator anti-drop system provided by the invention, passes through the multiple groups system being arranged on hoistway wall or guide rail
The stall condition of the mutually independent detecting elevator of moving cell simultaneously carries out independent braking, each brake unit all independent actions, i.e.,
Make there is one group of brake unit to break down, other brake units can still provide for braking, due to all brake unit simultaneous faults
Probability it is extremely low, therefore, it greatly improves the reliabilities of elevator anti-drop system；Fixed stall induction trigger device on elevator
Also emergency braking can be carried out, the anti-fall system of elevator is further improved according to predetermined value, the starting of independent triggers each group elevator brake
The reliability of system.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the stall induction trigger device in the embodiment of the present invention 2.
Specific embodiment:
Embodiment 1
A kind of segmented elevator anti-drop system, including elevator, guide rail and elevator are equipped with several groups in elevator borehole wall
Brake unit, brake unit component are sequentially arranged at from top to bottom on elevator borehole wall or guide rail, and brake unit includes acceleration
The components such as measuring instrument, elevator brake and controller, accelerograph and elevator brake are separately fixed at elevator
On the borehole wall or guide rail.The accelerograph is laser accelerometer, and the control device is PLC.Accelerograph
Data output end is connected with the data input pin of controller, and the data output end of controller is connected with elevator brake；Braking is single
The elevator acceleration information detected is passed to controller by the accelerograph in member, and controller sentences acceleration value
Disconnected, when acceleration value is greater than predetermined value, controller starts each group elevator brake and carries out emergency braking.Furthermore the braking is single
There are also alarm devices in member, and the data output end of the controller is connected with the data input pin of alarm device, when the control
When device starts the elevator brake, alarm device starts simultaneously to be given a warning.This segmented elevator anti-drop system, passes through cloth
It sets the stall condition of the mutually independent detecting elevator of multiple groups brake unit in hoistway wall and carries out independent braking, it is each
Brake unit all independent actions, even if there is one group of brake unit to break down, other brake units can still provide for braking, by institute
The probability of some brake unit simultaneous faults is extremely low, and therefore, it greatly improves the reliabilities of elevator anti-drop system.
Embodiment 2
A kind of segmented elevator anti-drop system, including elevator, guide rail and elevator are equipped on elevator borehole wall or guide rail
Several groups brake unit, brake unit component are sequentially arranged at from top to bottom on elevator borehole wall or guide rail, and brake unit includes
The components such as accelerograph, elevator brake and controller, accelerograph and elevator brake are separately fixed at electricity
On the borehole wall or guide rail of stair shaft, while also there is stall induction trigger device on elevator.As shown in Figure 1, stall induction triggering dress
It sets and fixes on the elevator 1, weight 4 is placed in compressed spring 2, can be transported along about 3 guide rod being fixed on device frame
It is dynamic.When lift is normally gone up and down, weight 4 is not contacted with the internal trigger 5 of triggering link mechanism.When lift stall decline,
Since with big decline acceleration, so weight 4 reduces the pressure of compressed spring 2, compressed spring 2 extends, and pushes weight 4
It is moved upwards along guide rod 3, thus push internal trigger 5 to drive connecting rod 6 and then external trigger 7 is pushed to forward extend out, triggering system
The dog point of dynamic device is stretched out to elevator or cage guide direction, triggering each group elevator brake starting, or triggering alarm device.
By changing the distance on guide rod between weight 4 and internal trigger 5, to adjust stall acceleration predetermined value.Fixed mistake on elevator
Fast induction trigger device also can carry out emergency braking, also more into one according to predetermined value, the starting of independent triggers each group elevator brake
Step improves the reliability of elevator anti-drop system.This device is mechanically that structure is safe and reliable, is triggered using gravity, is not necessarily to
Extra power, accidentally a possibility that hair, leakage hair, is small, is not interfered by environment electromagnetics.
Accelerograph is laser accelerometer, and the control device is single-chip microcontroller.The data of accelerograph are defeated
Outlet is connected with the data input pin of controller, and the data output end of controller is connected with elevator brake；In brake unit
The elevator acceleration information detected is passed to controller by accelerograph, and controller judges acceleration value, when
When acceleration value is greater than predetermined value, controller starts each group elevator brake and carries out emergency braking.Furthermore on the brake unit
There are also alarm device, the data output end of the controller is connected with the data input pin of alarm device, when the controller opens
When moving the elevator brake, alarm device starts simultaneously to be given a warning.This segmented elevator anti-drop system, by being arranged in
The stall condition of the mutually independent detecting elevator of multiple groups brake unit in hoistway wall simultaneously carries out independent braking, each braking
Unit all independent actions, even if there is one group of brake unit to break down, other brake units can still provide for braking, due to all
The probability of brake unit simultaneous faults is extremely low, and therefore, it greatly improves the reliabilities of elevator anti-drop system.In order to further mention
High anti-fall effect can also increase on anti-fall well and elevator original accelerometer and anti-fall device together in the bottom of elevator
Anti-drop method is carried out, multiple drop-proof measure can greatly improve the reliability of anti-drop system.
