Intelligent vibrating equipment and method
The invention discloses intelligent vibrating equipment and method, and relates to the technical field of concrete vibrating. The problem that the vibration compactness of concrete in a steel pipe column cannot be accurately detected through an existing nondestructive detection method is solved. The device comprises a vibrator, an ultrasonic sensing device and a control system, the ultrasonic sensing device is arranged in the vibrator, a plurality of exhaust holes are formed in the outer surface of the vibrator, and the ultrasonic sensing device is in signal connection with the control system. The method comprises the following steps: recording the vibration frequency, the duration and the concrete compactness of the vibrator under standard conditions through a test and taking the vibration frequency, the duration and the concrete compactness as set values; the vibrator and the ultrasonic sensing device are inserted into the concrete and vibrate according to a set value, the ultrasonic sensing device obtains an ultrasonic signal in the vibrated concrete in real time and transmits the ultrasonic signal to the control system, and the control system compares a measured value of the compactness of the concrete with the set value; when the two signals are consistent, the vibration frequency and amplitude of the vibrator are reduced; when the two signals differ greatly, the vibration frequency and the time length of the vibrator are increased until the signals are close to each other.
