step 1: based on the detection value of the pressure sensor, the use safety factor of the guide roller (412) is calculated by the following formula:
；
wherein,for the safety factor of the use of the guiding roller (412,)>For guiding the bending fatigue limit of the material of the roller (412), ->For guiding the effective stress concentration coefficient of the surface of the roller (412) subjected to stress +.>For guiding the surface quality coefficient of the roller (412), +.>For guiding the dimension influence coefficient of the bending of the roller (412)>For the pre-set stress amplitude of the guiding roll (412), is->For guiding the average stress conversion coefficient of the material of the roll (412) when it is stretched +.>For the maximum detection value of the pressure sensor, +. >Is the contact area of a single guide roller (412) with the ship body;
step 2: based on the calculation result in the step 1, the controller compares the use safety coefficient of the guide roller (412) with a preset safety coefficient, and when the use safety coefficient of the guide roller (412) is smaller than the preset safety coefficient, the controller controls the alarm to send an alarm prompt.
7. The ship body supporting device applied to a ship frame according to claim 1, wherein the first jacking device (21) and the second jacking device (22) are identical in structure, the first jacking device (21) and the second jacking device (22) comprise a jacking cylinder (211) and a stabilizing mechanism (212), one side of the jacking cylinder (211) is hinged with the first bracket (3), the other side of the jacking cylinder (211) is hinged with the trailer (1), the stabilizing mechanism (212) is fixedly arranged at the top of the trailer (1), and the output end of the stabilizing mechanism (212) is in sliding connection with the first bracket (3);
the stabilizing mean (212) includes second support (2121), first slide rail (2122), second slide rail (2123) and first sliding block (2124), second support (2121) is fixed to be set up at trailer (1) top, first slide rail (2122) is fixed to be set up in one side that second support (2121) is close to first support (3), one side slip setting of first sliding block (2124) is on first slide rail (2122), the opposite side slip setting of first sliding block (2124) is on second slide rail (2123), second slide rail (2123) is fixed to be set up on first support (3).
