Specific embodiment
The utility model is described in further detail with embodiment for explanation with reference to the accompanying drawing, and the mode of the utility model includes But it is not limited only to following embodiment.
As shown in Figures 2 and 3, the anti-dismounting tower crane monitoring system of total failure self-test, including,
Sensor is mounted in tower crane, for obtaining the basic parameter of tower crane operation;
Tower crane black box, connect with sensor, and the basic parameter of the tower crane operation for receiving sensor acquisition is simultaneously right Tower crane mechanical action is monitored and records;
Server 1 is connect, for receiving the tower of tower crane black box cyclical transmission by network transmission with tower crane black box The basic parameter of machine operation monitors tower crane real time execution parameter for safety manager and backs up;Server 1 is generally all pacified In Central Control Room;
Encoder connect with tower crane black box and connect with the shaft of the travel switch of tower crane 2, follows travel switch 2 Shaft rotates together and electric signal is sent to tower crane black box;Specifically, encoder passes through the row of shaft coupling 8 and tower crane The shaft of Cheng Kaiguan 2 connects;
Magnetic field detection sensor 3 is mounted on 4 power supply of motor of tower crane, is become for detecting alternating electromagnetism when motor 4 operates Change parameter;
Signal picker 5 is connect with magnetic field detection sensor 3, for acquiring the motor 4 of the detection of magnetic field detection sensor 3 Alternating electromagnetism running parameter when operating;
Signal processor is connect with signal picker 5 and tower crane black box, for receiving the electricity of the acquisition of signal picker 5 Tower crane black box is sent to after alternating electromagnetism running parameter and processing when machine operates;
Microswitch 6 is mounted on the main each operating point for enabling platform 7 of tower crane, for detecting the main each movement for enabling platform The movement of point;
Switching value acquisition module is connect with microswitch 6 and tower crane black box, for acquire microswitch 6 actuating quantity, 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.
