step 2: detecting height adjustment;
opening the laser level, loosening the slidable limiting block of the rear auxiliary support, starting the hydraulic oil cylinder by the computer, controlling the lifting height of the main support, stopping the lifting of the main support after the laser point is aligned with the middle part of the railing, and finally fixing the slidable limiting block of the rear auxiliary support by screwing the limiting block and fixing the handle;
and step 3: adjusting a contact device;
single-point detection: and opening the fixing ring, starting the horizontal servo hydraulic oil cylinder by the computer, stopping the oil cylinder from extending after the contact block is contacted with the railing, finely adjusting the position of the contact block, and closing the fixing ring to enable the fixing ring to tightly hold the railing.
Two-point detection: loosening the angle converter, rotating the contact device to be parallel to the railing, locking the angle converter, opening the two fixing rings, starting a horizontal servo hydraulic oil cylinder controller by a computer, stopping the extension of the oil cylinder after the two contact blocks are contacted with the railing, finely adjusting the positions of the contact blocks, aligning to the detection points, and closing the two fixing rings to enable the fixing rings to tightly hold the railing;
and 4, step 4: connecting a data acquisition processing device;
connecting a displacement sensor and a pressure sensor to a signal acquisition card, connecting the signal acquisition card to a computer, and recording initial data;
and 5: detecting the bearing capacity;
the computer controls the servo hydraulic oil cylinder to load, the magnitude of the loading force and the loading process are implemented according to a bearing force detection program in sections B.3 in a specification of urban bridge design Specification CJJ11-2011(2019 edition) 10.0.7 and a specification of glass and metal guard bar for buildings JG/T342-2012;
