The invention discloses a stepping type tower body safety inspection device and method for a tower crane standard knot, and the device comprises a stepping arm, the two ends of the stepping arm are each fixedly provided with a rotor motor, each rotor motor is provided with a support, each support comprises a stand column, a rotor of each rotor motor is fixed to a through hole of the corresponding stand column, and each support is provided with a movable arm rotation angle measurement module; a clamping plate I and a clamping plate II are oppositely and elastically hinged to the two sides of the bottom of the support, an electromagnetic chuck I and an acoustic emission sensor are arranged on the clamping plate I, and an electromagnetic chuck II and a vibration sensor are arranged on the clamping plate II. Acoustic emission and vibration detection are carried out on the tower body in a stepping inspection mode, the characteristic that the tower body standard knot structure size is consistent is utilized, paired electromagnetic chucks and stepping arms are adopted for alternate supporting and rotation, and the middle position of the main chord member can be detected in a stepping mode; the crack condition of main rod pieces of the tower body and the bolt loosening condition between standard knots can be detected, and the reliability and the inspection speed of tower body inspection are improved.
本发明公开了一种用于塔吊标准节的迈步式塔身安全巡检装置及方法,包括迈步臂,迈步臂的两端各固定有一个转子电机,转子电机配设有支座,支座包括立柱,转子电机的转子与立柱的通孔固定,支座设有动臂转角测量模块,支座底部的两侧相对弹性铰接有夹板Ⅰ和夹板Ⅱ,夹板Ⅰ上设有电磁吸盘Ⅰ和声发射传感器,夹板Ⅱ上设有电磁吸盘Ⅱ和振动传感器。本公开采用迈步巡检的方式,在塔身进行声发射和振动检测,利用塔身标准节结构尺寸一致的特点,采用成对电磁吸盘与迈步臂交替支撑和回转,可以迈步式检测主弦杆中间位置,能够检测塔身主要杆件的裂纹情况以及标准节之间的螺栓松动情况,提高塔身巡检的可靠性和巡检速度。
