Preferably, move the elbow plate 4 away from the cross tube 3 by 100 mm to reserve a suitable welding space for the elbow plate 4 after the subsequent overall hoisting, to avoid the elbow plate 4 penetrating the cross tube 3 being covered by the tube and unable to be welded inside.

[0039] S2. Install the stoppers 6 on the outer hull plate 5 along the direction of the cross tube 3 as the inner fulcrums. Specifically, two stoppers 6 fixed on the outer hull plate 5 are respectively arranged at the lower parts of the upper two cross tubes 3 of the integral structure of the crane shelf 1 and the hook box 2, and the two stoppers 6 at the lower part of each cross tube 3 are arranged at an angle of 45 degrees with the center of the cross tube 3 as the center to facilitate providing a stable supporting force.

[0040] S3. Add a support seat on the outside of the integral structure of the crane shelf 1 and the hook box 2 as the outer fulcrum; the purpose of making the integral structure of the crane shelf 1 and the hook box 2 stable and balanced can be achieved by using the support seat and the baffle.

[0041] In a specific embodiment of the present application, the support base specifically includes a column 9 vertically arranged on the ground and a screw jack support base 10 detachably arranged on the top of the column 9.

The screw jack support base 10 can move up and down to jack up the outer side of the integrated structure of the crane gantry 1 and the hook box 2.

[0042] Further, to achieve the adjustable jacking distance of the screw jack support base 10, the screw jack support base 10 includes a base detachably and fixedly connected to the top of the column 9. A threaded seat is fixedly arranged on the base, and a top rod that moves up and down is threadedly installed on the threaded seat. The top of the top rod is fixedly provided with a top plate, and the top plate abuts against the outer bottom of the integrated structure of the crane gantry 1 and the hook box 2.

[0043] S4. Weld the weld between the welding gusset 4 and the ship's outer plate 5, and conduct 100% flaw detection to avoid the problem of insecure welding.

[0044] S5. Connect one end of the telescopic threaded tie rod 8 to the main ship's outer plate 5, and the other end to the main cross tube 3 of the crane gantry 1 and the hook box 2; based on the slideway formed by the slot 31 in the cross tube 3 and the stop block 6, when the threaded tie rod 8 contracts, the integrated structure of the crane gantry 1 and the hook box 2 slides horizontally along the upper edge of the stop block 6 to contact the ship's outer plate 5 at the cross tube 3, so that the integrated structure of the crane gantry 1 and the hook box 2 is translated in place, avoiding the long-time hooking of the large gantry crane.

[0045] Specifically, the threaded tie rod 8 includes a sleeve and threaded rods threadedly installed at both ends of the sleeve. The end parts of the threaded rods are respectively detachably and fixedly connected to the ship's outer plate 5 and the cross tube 3. By rotating the sleeve, the installation length of the threaded rod can be adjusted to adjust the length of the threaded tie rod 8.

[0046] S6. Weld the weld between the cross tube 3 and the main ship's outer plate 5. There are specifically 6 cross tubes 3, and weld the weld between the slot 31 in the cross tube 3 and the gusset 4 to complete all the welding work of the crane gantry 1 and the main body of the hook box 2.

[0047] Specifically, the weld between the slot 31 in the cross tube 3 and the gusset 4 specifically includes: a slot 31 opposite to the gusset 4 is reserved at the end of the cross tube 3, the gusset 4 is inserted into the slot 31, and the gusset 4 and the cross tube 3 are welded.

[0048] S7. Remove the support base.

[0049] In the present invention, after pre-assembling and matching the crane shelf 1, the horizontal pipe 3 of the hook box 2 and the gusset plate 4 with the slot 31 on the ground, the gusset plate 4 is pulled away from the pipe by 100 mm to reserve a welding space for the gusset plate 4 after the subsequent overall hoisting. At the same time, 4 slideway stoppers 6 are welded on the outer hull plate 5, and a circular pipe of the upright column 9 + a screw jack support base 10 is added on the outside to solve the problem of insufficient stability during the installation process, so as to achieve the purpose of quickly hoisting in place and shortening the use time of the large gantry crane.

[0050] The present invention uses the process forward movement, utilizes the slot 31 of the horizontal pipe 3 to improve the matching of the slot 31, and ingeniously separates the operation modes such as the gusset plate 4. By using the simple stopper 6 and the circular pipe of the column + the screw jack support base 10, the problems of the stability of the main body installation and the translation in place are solved, and it has the characteristics of simple operation, quickness and convenience.

[0051] The above are only the preferred embodiments of the present invention.
