Respectively detecting device, driver, alarm are described below below,
Please earlier referring to shown in Figure 2, detecting device 26 comprises and Elastic Contact point 262, and Metal Contact sheet 261, Elastic Contact point 262 are separately fixed on the main drive shaft 24 of shaft coupling 20 and on the driven axle 25 of shaft coupling 20.Promptly, Metal Contact sheet 261 is fixed on the main drive shaft 24 of shaft coupling 20, Elastic Contact point 262 is fixed on the driven axle 25 of shaft coupling 20, Metal Contact sheet 261 can certainly be fixed on the driven axle 25 of shaft coupling 20, Elastic Contact point 262 is fixed on the main drive shaft 24 of shaft coupling 20, which kind of mode no matter, Metal Contact sheet 261 and Elastic Contact point 262 all should be in contact with one another when the shaft coupling operate as normal is connected.The Metal Contact plate shape be "
" type, being right angle Metal Contact sheet, the size that the interface width of Metal Contact sheet 261 should be adjusted into the shaft coupling gear wear limit allows width.During shaft coupling 20 work, if gear weares and teares in normal range, just the Metal Contact sheet 261 on the main drive shaft 24 is in allowing width; Contact point 262 on the driven axle 25 can not skidded off, and is equivalent to switch and is on-state, sees Fig. 3 a, is on-state as same regular tap.Otherwise after shaft coupling 20 gear wear overruns, the free clearance between gear strengthens.Especially when shaft coupling 20 heavy duties, improper displacement degree between the main drive shaft 24 of shaft coupling and the driven axle 25 more can exceed allowed band, thereby contact point 262 is skidded off, and is equivalent to switch off state this moment, ask for an interview Fig. 3 b, be off-state as same regular tap.This principle of work process is all the same when the shaft coupling rotating.
Please continue to consult shown in Figure 4,
Driver is actually an on-off circuit, and it comprises triode BG (9013), biasing resistor R1, R2, R3, and the input end of driver is connected with Elastic Contact point 262 by resistance R 1, and output end of driver and alarm join.Alarm comprises LED and hummer F, and LED and hummer F are connected in parallel between output end of driver and the power supply, promptly between the collector and power supply E of triode BG (9013).
This monitoring device also comprises wireless transmitter module TX301F and wireless receiving module TX301S (see figure 5), the output terminal that the input end of wireless transmitter module TX301F is driver connected, it is the collector of triode BG, the output terminal of module TX301F is a transmitting terminal, and wireless receiving module TX301S receives the wireless signal of wireless transmitter module emission.
In addition, this monitoring device also comprises the self power generation circuit, the self power generation circuit comprises coil L, permanent-magnet steel CG, rectifier bridge ZL, regulator block IC2, the axle that coil L is fixed on shaft coupling 20 upward and with shaft coupling 20 rotates synchronously, permanent-magnet steel CG places by the coil L, and can make coil L when rotated the magnetic line of force in one's power be made cutting movement, the input of coil L two ends and rectifier bridge ZL is joined, regulator block IC2 is received in the output of rectifier bridge ZL, the output of the regulator block IC2 device that receives the report for police service, wireless receiving module TX301S is received in the output of regulator block IC2, thinks that it provides power supply.
Please again in conjunction with Fig. 4, monitoring device principle of work of the present invention is described below:
GND among Fig. 4 is the metallic object of shaft coupling, as ground connection,
When shaft coupling is operated in dynamic heavy duty, when its wearing and tearing do not overstep the extreme limit again; Elastic Contact point 262 can not skid off at this moment, and it and Metal Contact sheet 261 continue to keep excellent contact (centrifugation of high speed rotating has more strengthened the pressure between contact point and the contact chip when working owing to shaft coupling).Because the low-resistance dividing potential drop effect of R1, the base stage of triode BG (9013) is in zero potential substantially and makes triode BG (9013) present cut-off state.At this moment, entire circuit is not worked, and energy consumption is economic.
When shaft coupling wearing and tearing dynamically present the limit when critical; Elastic Contact point 262 is because displacement is released souls from purgatory and skidded off this moment, and just it is separated (centrifugation of high speed rotating has more strengthened the separation between contact point and the contact chip when working owing to shaft coupling) with contacting of Metal Contact sheet 261.This moment triode BG base stage because the effect of resistance R 2 has been in positive potential, and make triode BG by by turning to conducting state rapidly.Entire circuit is started working, and driver start triggering circuit hummer F sends chimes of doom.The driven for emitting lights diode (LED) sends the light caution simultaneously, has just become a ring of light at the next high brightness luminous point of the situation of shaft coupling high speed rotating, and very eye-catching.Simultaneously, wireless transmitter module IC1 (TX301F) also starts working, and sends wireless modulated signals by the antenna end T of transmitter module IC1.
If this moment, equipment next door did not have personnel to inspect, this device can also send out an emergency signal by the Central Control Room of wireless launcher to Device Host, and allows Central Control Room receiving slave system.
Because this monitoring device is a device that needs work long hours, and is in for a long time among the high speed rotating state again, considers its centrifugation, so power supply (battery) can not be very big, need select the button cell of small rechargeable type for use.Right apparatus of the present invention power consumption is economic, but power saving also needs in time to replenish to battery again.Because external power supply inconvenience, this device has utilized the shaft coupling axle of high speed rotating to be combined into simple magnetic-pulse formula self power generation circuit, and by the button cell charging of regulator block to this device.
Among Fig. 4, the V+ of wireless transmitter module IC1 and V-be working power end, E is chargeable button cell.
Its principle of work of self power generation circuit is as follows:
When the shaft coupling axle whenever turns around, coil L also does once relative magnetic force line cutting motion with permanent-magnet steel CG, and the two ends at coil L produce the Pulse Electric kinetic potential, through rectifier bridge ZL rectification, cushion (filtering) by capacitor C, after regulator block IC2 (7805) voltage stabilizing, output is carried out constant-voltage charge through anti-backflow diode D to button cell E.
The dynamic wear limit signal receiver of shaft coupling that Fig. 5 is made up of wireless receiver module TX301S and another triode (9013), relay J.The signal that sends when transmitter module is received when module receives and can drives triode immediately and make relay J work, the closed immediately conducting of the normally opened contact JK of relay; This switching signal will can be made Long-distance Control or point out relevant operating personnel.
This shows that monitoring device of the present invention has solved effectively and need carry out in the real time on-line monitoring shaft coupling, want for a long time to solve but four difficult problems always not solved; 1, detection of dynamic.2, the working power problem of pick-up unit.3, the shaft coupling Dynamic Signal extracts problem.4, dynamically the transmission of alert signals sends problem.This device also has simple and reliable for structure, but wide popularization and application is among the real-time monitoring of transmission in all kinds of mechanical axis, as industries such as metallurgy, mine, lifting transportations, also be applicable to all kinds of machineries such as oil, chemical industry, universal machine the axle be in the real-time monitoring of transmission.
