Background technology
At present, the trash in the hydraulic engineering particularly rotary type trash cleaning device adopted the safety pin overload protection morely.This type overload protection arrangement is that separable wheel hub and sprocket wheel are installed on final drive shaft; safety pin is installed in the drilling of wheel hub and sprocket wheel; when mechanical overload occurring; safety pin is cut off by sprocket wheel; the shift fork that is installed on the sprocket wheel touches travel switch, thus the control signal of sending and cut off motor power protection drive system.But in actual applications because the wearing and tearing of power transmission shaft and axle sleeve cause travel switch and shift fork gap to become big, taking place to touch travel switch when safety pin is cut off, can't send control signal, cause motor idle running to cause sprocket wheel then and the wheel hub frictional heat causes device damage.Simultaneously, because shift fork is installed on the sprocket wheel, travel switch is installed on the static support of bearing, installs and adjusts inconvenience.
Summary of the invention
In order to overcome the shortcoming of present overload protection arrangement reliability deficiency; the invention provides a kind of trash intelligence overload protection arrangement; not only timely controlling and driving motor stops when equipment generation safety pin cuts off, the while output alarm signal, and signal supervisory instrument has also been simplified installation and adjustment process.
The technical solution adopted for the present invention to solve the technical problems is: trash intelligence overload protection arrangement; comprise safety pin, actuating mechanism and signal supervisory instrument; checkout gear is by forming near switch and profile of tooth inductive disks; the profile of tooth inductive disks is fixed on a power transmission shaft end; on the described bush seat that is fixed on same transmission axle head near the switch correspondence; connect a control module signal input part near switch signal line, by this control module controlling and driving motor rotation.When power transmission shaft rotated under chain wheel driving, rotation of profile of tooth inductive disks was sent to control module near the signal of inductive switching, this control module by to the pulse signal analysis of input, calculate and control output.Cut off when mechanical overload plug takes place, power transmission shaft stops operating, and count pulse is lower than initial set value, and the output relay normally-closed contact disconnects, and motor stops; Relay normally open point adhesive simultaneously, alarm sends sound and light signal.
Described control module is made up of electric power loop, signal input circuit, relay output loop, single-chip microcomputer U1, the control module outside line is connected with control module by P1, P2, P3 binding post, wherein, 1,4 defeated 220VAC power supplys in the P1 terminal, through transformer D1 transformation, be transformed into 12VDC and 5VDC through bridge rectifier D 2/D3, capacitor filtering, pressurizer IC1/IC2; 1,3 of P3 terminals connect the 12VDC power supply, and terminal 2 connects holding wire, through 15 pin of photoisolator IC4 input single-chip microcomputer U1; Single-chip microcomputer output port 6 pin are by photoisolator IC3, and by triode control relay TR1 coil, relay TR1 has each one of normally-open normally-close contact, is connected with alarm with motor control loop by the P3 terminal; 19 pin of single-chip microcomputer U1 and 18 pin are the oscillator input/output port, external 12MHz crystal oscillator; 9 pin are the RESET input mouth, the reset circuit that external button, resistance and electric capacity are formed, and 40 pin and 20 pin are the power supply port, connect respectively+positive and negative terminal of 5V power supply.
Described control module is made up of electric power loop, signal input circuit, relay output loop, single-chip microcomputer U1 AT89C52 and the single-chip microcomputer loop that resets.Because near the inductive switching sensitivity, single-chip microcomputer is handled reliable rapidly, will in time be stopped in case safety pin cut-out drive motors occurs.
Trash intelligence overload protection arrangement is equipped with wheel hub and sprocket wheel at the power transmission shaft right-hand member, and safety pin is installed in the drilling of wheel hub and sprocket wheel; At the power transmission shaft left end, with set bolt profile of tooth inductive disks 1 is fastened on the power transmission shaft 5, be fixed on the bearing box connecting plate by mounting panel near switch.
The invention has the beneficial effects as follows that the Based Intelligent Control by single-chip microcomputer substitutes machinery controls such as original shift fork and travel switch, it is in time reliable not only to detect control, and the induction component structure simplifies, install adjust convenient.
