It should be noted that, in the present embodiment, the length measuring completion detector 4 mainly uses the light emitting element 41 and the light receiving element 42 in cooperation, where the light emitting element 41 is an infrared ray emitter, the light receiving element 42 is an infrared ray receiver, the light emitting element 41 and the light receiving element 42 are arranged on both sides of the anchor bolt 2, and the light emitting element 41 and the light receiving element 42 are at a set height such that the light emitting element 41 and the light receiving element 42 correspond to the anchor bolt 2, the infrared ray emitted from the light emitting element 41 can be shielded by the anchor bolt 2 when the anchor bolt 2 is in contact with the length measuring roller 6, the infrared ray can not be received by the light receiving element 42, the anchor bolt 2 can not shield the infrared ray emitted from the light emitting element 41 when the anchor bolt 2 leaves the length measuring roller 6, and the light receiving element 42 can normally receive the infrared ray.
In fact, the length measurement completion detector 4 is connected to the corresponding microprocessor module, and when the light receiving element 42 receives the light emitted from the light emitting element 41, the length measurement completion detector 4 outputs a signal to the microprocessor module, and at this time, the microprocessor module does not count the number of pulses emitted from the angle encoder 7 until the light emitted from the light emitting element 41 is shielded again by the anchor bolt 2, and when the light receiving element 42 does not receive the corresponding infrared ray, the microprocessor module restarts counting the number of pulses emitted from the angle encoder 7.
During the use, when 2 moves forward by drive roller 1 drive crab-bolt, when 2 contacts with length measuring gyro wheel 6 of crab-bolt, under the action of gravity, 2 compress tightly length measuring gyro wheel 6 of crab-bolt, when 2 moves forward of crab-bolt, can take length measuring gyro wheel 6 to follow the rotation in step, and then drive angle encoder 7 synchronization motion, angle encoder 7 detects length measuring gyro wheel 6 pivoted angular displacement to microprocessor module output corresponding pulse, microprocessor module receives and handles the pulse, and then measure 2 lengths of crab-bolt.
At this time, since the lever blocks the infrared rays emitted from the light emitting element 41, the light receiving element 42 does not receive the corresponding infrared rays, and the micro-processing module normally receives and processes the pulses.
Because the crab-bolt 2 is heavier, when crab-bolt 2 moves forward fast with certain speed, can lead to length measuring gyro wheel 6 to rotate with faster, when crab-bolt 2 breaks away from length measuring gyro wheel 6, under the inertia effect, length measuring gyro wheel 6 appears the condition that continues to rotate easily, lead to detection error easily, at this moment, because the member bar leaves length measuring gyro wheel 6, the infrared ray that the light emission part 41 that corresponds length measuring gyro wheel 6 and arranges sent no longer receives the member bar and blocks, light receiving part 42 can normally receive the infrared ray, at this moment, length measuring is accomplished detector 4 and can be to microprocessor module output corresponding signal, microprocessor module no longer receives the count pulse that the follow-up angle encoder 7 of processing sent, but calculate crab-bolt 2 length with the count pulse quantity before as the standard, and then eliminated length measuring gyro wheel 6 because of inertial roll brought measurement error, guaranteed measurement accuracy.
It should be noted that the length measurement completion detector itself may have a corresponding control unit, when the light receiving part receives infrared rays, the control unit may send a corresponding signal to the microprocessor module to indicate that the anchor bolt leaves the length measurement roller, the microprocessor module does not process the pulse information output by the angle encoder any more, and when the light receiving part does not receive infrared rays again, the control unit may send a corresponding signal to the microprocessor module to indicate that the anchor bolt drives the length measurement roller to roll, and the microprocessor module needs to process the pulse information output by the angle encoder, so as to implement the rod length measurement of the anchor bolt.
