Abstract
A kind of disintegrating machine with online auxiliary detection device, tachometer disc (2) is arranged on the power output shaft of driving motor (1), one group of sensor block (3) difference annular array is on tachometer disc (2), speed sensor (4) by support installing in frame (1-1), the signal output part of speed sensor (4) is connected with the signal input part signal of current transducer (6) by current transformer (5), and the signal output part of current transducer (6) is connected with the signal input part signal of PLC (7).The utility model advantage is: the ruuning situation judging motor and driving belt, when finding that " turning round " is many, changing belt in time and can to a certain degree reduce broken power consumption.
Description
Technical field
The utility model is specifically related to a kind of disintegrating machine with online auxiliary detection device.
Background technology
at present, belt transfer equipment is more in cement plant, mainly limestone crushing motor, gypsum broken motor, chamotte crushing motor, and these equipment have a general character, is exactly that power of motor is comparatively large, utilizes the degree of tightness journey of speed measurement switch and current curve comprehensive descision belt.Detect motor and belt ruuning situation, the dynamo-electric acc power 900KW of limestone crushing, 6 grades of motors, limestone crushing machine work under bad environment, and its mode of being in transmission connection is belt transmission, along with long running, the tensile force of belt is deteriorated, and relatively with the frictional force of drive reduces, and is just easy to occur belt creep and " throws switch " or the phenomenon such as part " coming off ".Unnecessary power consumption also just lost, but now middle control operator only relies on the current ripple level of the broken motor of hammer to judge motor ruuning situation, the very difficult operation hidden danger finding to exist.
Utility model content
The purpose of this utility model is exactly for deficiency above-mentioned at present, and provides a kind of disintegrating machine with online auxiliary detection device.
The utility model comprises driving motor and the frame of disintegrating machine body, online auxiliary detection device is also had in it, online auxiliary detection device comprises tachometer disc, one group of sensor block, speed sensor, current transformer, current transducer and PLC, tachometer disc is arranged on the power output shaft of driving motor, one group of sensor block difference annular array is on tachometer disc, speed sensor by support installing in frame, and the probe of speed sensor is corresponding with one of them position of one group of sensor block, distance between the probe of speed sensor and one group of sensor block is 8mm, the signal output part of speed sensor is connected with the signal input part signal of current transducer by current transformer, the signal output part of current transducer is connected with the signal input part signal of PLC.
The electric current of driving motor is connected with the signal input part signal of PLC by current sensor.
The utility model advantage is: the ruuning situation judging motor and driving belt, when finding that " turning round " is many, changing belt in time and can to a certain degree reduce broken power consumption.
accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is operation principle structural representation.
Detailed description of the invention
As Fig. 1, shown in 2, the utility model comprises driving motor 1 and the frame 1-1 of disintegrating machine body, it is characterized in that it also has online auxiliary detection device, online auxiliary detection device comprises tachometer disc 2, one group of sensor block 3, speed sensor 4, current transformer 5, current transducer 6 and PLC 7, tachometer disc 2 is arranged on the power output shaft of driving motor 1, one group of sensor block 3 difference annular array is on tachometer disc 2, speed sensor 4 by support installing on frame 1-1, and the probe of speed sensor 4 is corresponding with one of them position of one group of sensor block 3, distance between the probe of speed sensor 4 and one group of sensor block 3 is 8mm, the signal output part of speed sensor 4 is connected with the signal input part signal of current transducer 6 by current transformer 5, the signal output part of current transducer 6 is connected with the signal input part signal of PLC 7.
The electric current of driving motor 1 is connected with the signal input part signal of PLC 7 by current sensor.
Working method: when driving motor 1 operationally, whether speed sensor 4 detects motor rotation speed by one group of sensor block 3 on induction tachometer disc 2, detect motor work well according to motor rotation speed.
