Because the four connecting holes 14 are positioned on the circumference with the same radius as the steam generator 53, the connection points of the lifting lugs 36 and the steam generator 53 are uniformly distributed on the circumference of the steam generator 53, so that when the inhaul cable 38 is used for adjusting and installing the steam generator 53, the balance is better, and the accuracy of adjusting and installing is improved.
Wherein both the pressure vessel cylinder 52 and the steam generator 53 are substantially in place prior to performing this step, the device of the present invention functions to re-fine tune the pressure vessel cylinder 52 or the steam generator 53 to adjust the pressure vessel cylinder 52 or the steam generator 53 to the designed installation position and to the level, i.e. the alignment, leveling action.
As shown in fig. 1-2, in the fourth step, the pressure vessel cylinder 52 and the steam generator 53 are adjusted to be identical in this step, and the pressure vessel cylinder 52 is adjusted to be installed as an example. The hydraulic pump station 22 is utilized to control the Z-direction oil cylinders 213 of the four three-dimensional hydraulic adjusting machines 21, so that the four Z-direction oil cylinders 213 are lifted, the lifting of the Z-direction oil cylinders 213 drives the structural beam 10 to move upwards, the structural beam 10 lifts the inhaul cable 38, the inhaul cable 38 lifts the pressure container cylinder 52, and after the pressure container cylinder 52 is lifted, the position of the pressure container cylinder 52 can be adjusted.
As shown in fig. 1-2, the fifth step is still described by taking the adjustment of the installation position of the pressure vessel cylinder 52 as an example, the laser tracker 42 of the measurement system 40 is used to measure the position of the pressure vessel cylinder 52 and send the measured value to the analysis device 41, the analysis device 41 decodes the measured value sent by the laser tracker 42, and then compares the decoded measured value with the designed installation position of the pressure vessel cylinder 52 to obtain a deviation value of the measured value and the designed installation position of the pressure vessel cylinder 52, where the deviation value includes deviation values in the X direction, the Y direction and the Z direction, and meanwhile, since there are more pipes on the pressure vessel cylinder 52, in order to adjust the pipe orifice direction of the pipe, the pressure vessel cylinder 52 needs to be rotated around the Z axis.
The deviation value calculated by the analysis device 41 is manually input to the synchronization console 23 of the hydraulic pressure adjustment system 20, or copied to a mobile storage device, and the mobile storage device is connected to the synchronization console 23 to introduce the deviation value to the synchronization console 23. After receiving the deviation value, the synchronous control console 23 sends the deviation value to four hydraulic pump stations 22, the hydraulic pump stations 22 control an X-direction oil cylinder 211, a Y-direction oil cylinder 212 and a Z-direction oil cylinder 213 of the three-dimensional hydraulic adjustment machine 21 according to the deviation value, the structural beam 10 is driven to move in the X direction by extending or retracting the X-direction oil cylinder 211, the structural beam 10 is driven to move in the X direction by a guy cable 38, the pressure container cylinder 52 is further adjusted to move in the X direction, and likewise, the position of the pressure container cylinder 52 in the Y direction is adjusted by extending or retracting the Y-direction oil cylinder 212, the position of the pressure container cylinder 52 in the Z direction is adjusted by descending or jacking the Z-direction oil cylinder 213, and the rotation of the pressure container cylinder 52 around the Z axis is realized by controlling the movement of the structural beam 10 in the X direction and the Y direction simultaneously; after the position adjustment of the pressure vessel cylinder 52 is finished, this step needs to be repeated several times, because the pressure vessel cylinder 52 is subjected to factors such as swinging of the guy cable 38, and after one adjustment, the actual position and the designed installation position will deviate, and the purpose of repeating this step several times is to continuously reduce the deviation, so that the pressure vessel cylinder 52 is more and more close to the designed installation position, until the pressure vessel cylinder 52 is adjusted to the designed installation position and to the horizontal.
Sixth, after the pressure vessel cylinder 52 is adjusted to the design installation position and adjusted to the horizontal, the hydraulic pump station 22 controls the Z-direction oil cylinder 213 of the three-dimensional hydraulic adjustment machine 21 to descend, so that the structural beam 10 moves downwards, and the pressure vessel cylinder 52 falls down to be installed in place.
