Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is elaborated, and following examples are to explanation of the present utility model, and the utility model is not limited to following embodiment.
As shown in Figure 1, the one that the utility model provides tests the speed protective device, comprise disintegrating machine 1, reductor 2 and motor 3, the crusher shaft 1.1 of described disintegrating machine 1 is connected to the slow-speed shaft 2.2 of reductor 2, the high speed shaft 2.1 of reductor 2 connects the output shaft 3.1 of motor 3, and is also provided with nylon rod 4 between the output shaft 3.1 of described high speed shaft 2.1 and motor 3; The slow-speed shaft 2.2 of described reductor 2 is installed a buting iron 5, one fixed support 6 is set below described slow-speed shaft 2.2, one proximity switch 7 is installed above described fixed support 6, described proximity switch 7 and buting iron 5 with the use of, the signal output part 8 of described proximity switch 7 connects programmable controller PLC 9, the output of described programmable controller PLC 9 connects the shutdown switch 3.2 of motor 3, and the output of described programmable controller PLC 9 also connects a single roller low-speed alarm device 10.
Be provided with one piece of buting iron 5 in the side of the slow-speed shaft 2.2 of reductor 2, arrange a proximity switch 7, position is corresponding with buting iron 5 simultaneously, by coordinating of proximity switch 7 and buting iron 5, realizes testing the speed to slow-speed shaft 2.2; Slow-speed shaft 2.2 often turns around, and proximity switch 7 can sense a pulse signal and send programmable controller PLC 9 to by signal output part 8, is tested the speed by proximity switch 7 and buting iron 5 pairs of slow-speed shafts 2.2, can not abrasion machine, and response frequency is high simultaneously; Its PLC9 pulse signals time of PLC technology contrasts, if receive the burst length to be less than setting-up time, devices illustrated works well; If the burst length received is greater than setting-up time; illustrate that disintegrating machine 2 rotating speed is slack-off; judge that the nylon rod 4 between motor 3 and reductor 2 is cut off; send warning stopping signal; notify related personnel's check processing; decrease the intermediate link of control section, affect without other factors, warning accuracy is high.
In the present embodiment, described proximity switch 7 is vortex type proximity switch.The environment resistant jamming performance of vortex type proximity switch is good, and response frequency is high, simultaneously cheap.
In the present embodiment, described proximity switch 7 is 2-15mm with buting iron 5 spacing, and preferred distance is 5mm.In this distance, proximity switch 7 is not subject to the external interference such as environmental change, power-supply fluctuation and produces misoperation.
