The method comprises the following steps that a detection stage of shear force detection is carried out, wherein the specific process of the detection stage is that the output ends of two groups of hydraulic cylinders 2 synchronously downwards press the top of a spandrel girder, wherein the output end of each group of hydraulic cylinders 2 is provided with a pressure sensor (not shown in the figure), an upper computer (not shown in the figure) is arranged in a detection area and used for displaying the compression numerical value of the spandrel girder in real time, when the compression of the spandrel girder breaks, the upper computer can display the shear force value of the current spandrel girder, and when the spandrel girder breaks, scattered broken stones can fall down on a horizontal supporting cloth 3;
when the shear force detection is finished, the blanking stage is entered, the concrete process is that two groups of lifting frames 4 rise synchronously, the lifting beams which are horizontal gradually approach the spandrel girder upwards, when the lifting beams 3 are contacted with the spandrel girder, the output ends of the air cylinders 9 begin to retract, the winding wheels 6 wind the lifting ropes 7, the four end corners of the lifting beams 3 gather towards the spandrel girder, finally the lifting beams are covered by the lifting beams 3, after the lifting beams are covered by the lifting beams, the air cylinders 9 stop working, the winding wheels 6 are locked again by the locking mechanism, the lifting frames 4 begin to rise, after that, the lifting beams are transported to the blanking zone by the lifting frames 4, after the lifting frames 4 translate into the blanking zone, the lifting frames 4 begin to descend, the lifting beams 3 are gradually unfolded horizontally in the descending process, and after the lifting beams 3 are contacted with the ground, the lifting beams on the lifting beams 3 can be transported through the lifting beams (shown in the position diagram), wherein the lifting beams are covered by the lifting frames 3, and the lifting beams can be broken through the detection of the lifting beams, and the load can be broken in the blanking stage through the detection of the lifting beams.
The foregoing examples merely illustrate one or more embodiments of the invention, which are described in greater detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
