The following describes the method of use of the device of the invention:
as shown in fig. 1, in the first step, four three-dimensional hydraulic adjusting machines 21 are arranged on the upper surface of a reactor compartment wall 50, and the arrangement positions of a hydraulic pump station 22 and a synchronous control console 23 are not required. In the next step, the structural beam 10 is placed on the four three-dimensional hydraulic adjustment machines 21, and the Z-direction cylinders 213 of the three-dimensional hydraulic adjustment machines 21 are inserted into the fixing grooves of the lower surface of the structural beam 10, so that the positions of the four three-dimensional hydraulic adjustment machines 21 should meet the requirement that the structural beam 10 can be placed on the four three-dimensional hydraulic adjustment machines 21, and the Z-direction cylinders 213 of the four three-dimensional hydraulic adjustment machines 21 are inserted into the four fixing grooves of the lower surface of the structural beam 10.
As shown in fig. 1, in the second step, the structural beam 10 is placed on four three-dimensional hydraulic adjusting machines 21, and four Z-direction cylinders 213 are inserted into four fixing grooves on the lower surface of the structural beam 10, and the Z-direction cylinders 213 serve to support the structural beam 10 on one hand and drive the structural beam 10 to move on the other hand.
Preferably, the four three-dimensional hydraulic adjusting machines 21 are rectangular on the reactor compartment wall 50, and the fixing grooves are distributed at four corners of the structural beam 10, so that the structural beam 10 can be conveniently placed on the four three-dimensional hydraulic adjusting machines 21 and the Z-direction oil cylinders 213 are inserted into the fixing grooves of the structural beam 10.
As shown in fig. 1 and 3, in a third step, the hydraulic lifters 31 of the guy wires 38 are fixed to the upper surface of the structural beam 10 at the ports of the connection holes 14, the steel strands 32 are penetrated through the connection holes 14, and the pin holes 35 of the connection pulling plates 34 are connected with the top cover lifting lugs of the metal core case 51 through pin shafts to connect the guy wires 38 with the metal core case 51. Wherein the hydraulic lifter 31 may be fastened to the structural beam 10 by bolts. Because the four connecting holes 14 are uniformly distributed on the circumference with the same radius as the metal core shell 51, the connecting points of the connecting pull plate 34 and the metal core shell 51 are also uniformly distributed on the circumference of the metal core shell 51, so that when the inhaul cable 38 is used for adjusting and installing the metal core shell 51, the balance is better, and the adjustment and the installation are more accurate.
Wherein, the metal core shell 51 is generally in place before this step is performed, the device of the invention has the functions of fine-tuning the metal core shell 51 to adjust the metal core shell 51 to the designed installation position and to the horizontal, namely the functions of alignment and leveling; secondly, after the metal core case 51 is adjusted to the installation position and to the horizontal, the metal core case 51 is lifted up by about 1.2m to perform the operation of installing the limit key on the sidewall of the reactor compartment wall 50.
As shown in fig. 1 and 4, in the fourth step, the hydraulic pump station 22 is used to control the Z-directional cylinders 213 of the four three-dimensional hydraulic adjusting machines 21, so that the four Z-directional cylinders 213 are all lifted, and the lifting of the Z-directional cylinders 213 drives the structural beam 10 to move upwards, so that the structural beam 10 lifts the cable 38, the cable 38 lifts the metal core shell 51, and after the metal core shell 51 is lifted, the position of the metal core shell 51 can be adjusted.
As shown in fig. 1, in a fifth step, the laser tracker 42 of the measurement system 40 is used to measure the position of the metal core shell 51, and the measured value is sent 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 metal core shell 51 to obtain a deviation value of the measured value and the designed installation position of the metal core shell 51, where the deviation value includes deviation values in the X direction, the Y direction and the Z direction, and meanwhile, since there are more tubes on the metal core shell 51, in order to adjust the tube opening direction of the tubes, the metal core shell 51 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 guy cable 38 is driven to move in the X direction by a metal core shell 51, so that the position of the metal core shell 51 in the X direction is adjusted, and likewise, the position of the metal core shell 51 in the Y direction is adjusted by extending or retracting the Y-direction oil cylinder 212, the position of the metal core shell 51 in the Z direction is adjusted by descending or jacking the Z-direction oil cylinder 213, and the rotation of the metal core shell 51 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 metal core case 51 is finished, this step needs to be repeated many times, because the metal core case 51 is subjected to factors such as swinging of the guy cable 38, and after one adjustment, the actual position and the design installation position will deviate, and the purpose of repeating this step many times is to continuously reduce the deviation, so that the metal core case 51 is more and more close to the design installation position until the metal core case 51 is adjusted to the design installation position and to the level.
Sixth, after the metal core shell 51 is adjusted to the design installation position and adjusted to the horizontal, the hydraulic pump station 22 controls the Z-cylinder 213 of the three-dimensional hydraulic adjustment machine 21 to descend so that the structural beam 10 moves downward, and the metal core shell 51 falls down to be installed in place.
Seventh, the steel strand 32 is lifted by the hydraulic lifter 31 of the guy cable 38, and during the lifting process, the position of the hydraulic lifter 31 is not moved, the steel strand 32 between the hydraulic lifter 31 and the bottom anchor 33 is gradually shortened to lift the metal core case 51, lift the metal core case 51 by about 1.2m, and then install a limit key on the side wall of the reactor compartment wall 50. The limit key has a limit fixing function on the metal core shell 51, and is to be installed on the side wall of the reactor compartment wall 50, and since the distance between the metal core shell 51 and the reactor compartment wall 50 is small, the metal core shell 51 needs to be lifted by about 1.2m to have a space for installing the limit key. Because the metal core case 51 needs to be lifted by about 1.2m, displacement of a large distance of 1.2m cannot be completed by using the three-dimensional hydraulic adjustment machine 21, the guy cable 38 of the device of the invention has a lifting function to realize large-distance displacement of the metal core case and complete the installation of the metal core case 51. After the limit key is installed, the hydraulic lifter 31 lowers the steel strand 32, and the metal core case 51 falls into place.
