And the data of acquisition are sent to tower crane black box.
Wherein, tower crane is assembled with a travel switch 2 on the axis of each motor 4 generally all there are three motor 4, this
Travel switch 2 is typically all that the factory of tower crane producer is preceding just configured, penetrates motor shaft and travel switch axis by a bolt 9
On, so that motor 4 and travel switch 2 is rotated synchronously and the turbine and worm inside travel switch 2 is driven to rotate.When turning to setting
When limit maximum position or minimum position, so that internal contact is switched on and off the contactor in control tower Electrical Control cabinet and release
Movement to dangerous direction.Therefore, encoder is three and connect respectively with the shaft of three travel switches 2 of tower crane.Magnetic field
Detection sensor 3 is three and is separately mounted on the power supply of three motors 4 of tower crane that signal picker 5 is three and divides
It is not connect with three magnetic field detection sensors 3.
The basic parameter of tower crane operation generally comprises hoist, amplitude, height, angle of revolution information, therefore sensor is usual
Setting four, respectively weight sensor, amplitude sensor, height sensor and rotary sensor are respectively used to monitoring tower crane
Running relevant parameter.
Scene is in use, be attached synchronization action by bolt 9 between travel switch 2 and motor 4, because being using hard
Connection, prolonged 4 start and stop of motor are very big to the impact of bolt 9, occur bolt 9 often and are sheared fracture and obscission,
At this moment travel switch 2 just loses limit spacing protective effect.The present embodiment is used other the one of the shaft of travel switch 2
Head installation encoder come assist carry out operating parameter measurement and mechanical trip limit mechanical breakdown judgement.Encoder passes through connection
Axis device is connected with the shaft of travel switch, because being between the two elastic connection, impact resistance, and high reliablity.When motor rotation
When, motor shaft drives travel switch and encoder to rotate together.Magnetic field detection sensor on motor power simultaneously is used
Change come alternating electromagnetism when detecting motor operating to detect whether motor operates.
Specifically, for the mechanical breakdown of travel switch, host, which is worked as, detects that (magnetic field detection passes motor in operation
Sensor has signal output), but encoder output does not change, and can judge to connect between motor and travel switch de-
It falls, and prompts tower crane driver by monitoring system alarming and be sent to server by wireless network to notify administrator
Member.Three encoder curent change situations of three motors installation in tower crane are as follows:
For sensor (weight sensor, amplitude sensor, height sensor and rotary sensor) failure, tower crane operation
Shi Taji black box detects that signal processor signal exports, and illustrates corresponding motor action operation；It should drive at this time corresponding
Encoder rotation, encoder is also because of spinning movement, and supply current also increases, and tower crane black box also detects that this electric current
Value；In main enable microswitch is installed on platform on each operating point simultaneously, and is sent into tower crane after acquiring by switching value acquisition module
Black box, tower crane black box must can substantially be estimated to obtain current sensor (weight sensor, amplitude according to aforementioned three data
Sensor, height sensor and rotary sensor) input signal numberical range, by with the practical data read of sensor into
Row comparison can effectively judge, whether the working condition of current sensor is normal, form a kind of closed loop detection, improve tower crane fortune
Capable safety.Various information enter after tower crane black box and sensor (weight sensor, amplitude sensor, height sensor
And rotary sensor) the height read in real time, amplitude, weight, pass to server background data after the information package of angle of revolution
Library.In main enable microswitch is installed on platform on each operating point, and is sent into tower crane black box after acquiring by switching value acquisition module
Son realizes the recording and storage to driver to tower crane operation real-time action.The operation note for recording driver, for thing
Afterwards failure perhaps crash analysis when can be very good to learn caused by equipment or correlate meter problem or due to operator
Caused by member's reasonable operation lack of standardization.
Existing tower crane black box sub-monitoring system is all unable to active detecting from the failure of each sensor, for example, luffing
Sensor failure (such as: the connection pivot pin of amplitude-change speed reducer and sensor falls off), tower crane black box can not detect this
The display of one failure, luffing and torque is exactly false.This consequence is very serious, less serious case's false alarm, severe one meeting
Cause the major accident that tower crane is tumbled.The utility model is detected by the linkage of electricapparatus, can determine whether sensor during operation
Whether mechanical connection falls off and sensor body abnormality, and by corresponding warning note driver, also by wireless
Network transmission submits supervisor to server background, forms a kind of closed loop detection, greatly improves the safety of tower crane operation.
Above-described embodiment is only one of preferred embodiments of the present invention, should not be taken to limit the utility model
Protection scope, as long as the utility model body design thought and mentally make have no the change of essential meaning or profit
Color, it is solved the technical issues of it is still consistent with the utility model, the protection scope of the utility model should all be included in
Within.
