[0002] In the process of ship construction, combined with different ship types, structural types and construction methods, there will be some lifting points arranged in the position of the structural shielding area when designing the lifting scheme. Taking the torsion-resistant box segment of a container ship as an example, the segment is stored in the general assembly site using steel piers and is turned over by a 600T gantry crane. The lifting points are mainly arranged on the main deck and the inner shell longitudinal wall. The lifting point located on the inner shell longitudinal wall can be hooked by the construction personnel climbing the tool ladder on the inner shell longitudinal wall, but it is very difficult to hook the lifting point located on the main deck in the shielding area. The lifting point is located below the hatch coaming, about 1.7m away from the hatch coaming top plate and about 3.0m away from the ground. The construction personnel need to push the wire rope to hook it, but the wire rope has a certain rigidity and is heavy. The whole hooking process needs 6 people to complete, 4 of whom push the wire rope, and the other 2 connect the wire rope with the lifting point through the shackle. The whole hooking process is time-consuming, low in efficiency, difficult and has certain safety hazards. SUMMARY

DETAILED DESCRIPTION

[0032] The specific embodiments of an auxiliary tooling applied to the hanging and connecting of a shielding area segment and a use method thereof provided by the application are further described in combination with the drawings and examples.

[0033] As Figure 3-4As shown, an auxiliary tooling used for segmented hanging of a shielding area is used to assist in connecting the lifting points of the shielding area when the torsion box segment 1 turns over, and includes a U-shaped tooling body 6, a steel wire connecting rope 7 and a shackle 8. Among them, a side wing plate of the tooling body 6 is provided with a plurality of lifting ears 601 at equal intervals along its length direction near the open end; the top two ends of the bottom plate of the tooling body 6 are provided with fixing ears (not marked in the figure); the steel wire connecting rope 7 is fixed to the bottom plate of the tooling body 6 through the fixing ears. It is worth noting here that one end of the steel wire connecting rope 7 is connected to the shackle 8, and the other end is a free end for connecting to the lifting point of the shielding area. Preferably, the tooling body 6 is made of ordinary marine steel plate or weldable ordinary low-alloy steel material.

[0034] Preferably, in order to ensure stability during the lifting process, the number of the lifting ears 601 on the top of each side wing plate of the tool body 6 is at least two and they are symmetrically arranged.

[0035] like Figure 2 As shown, the torsion box segment 1 comprises a main deck 102, an inner hull longitudinal wall 103, and a side shell 104. A hatch coaming 101 is horizontally disposed at the top edge of the main deck 102; a plurality of steel buttresses 2 are disposed at the bottom of the side shell 104, through which the torsion box segment 1 is placed on the assembly floor.

[0036] Several first lifting points 3 are evenly spaced along the length of the inner hull longitudinal wall 103, on its top side, away from the hatch coaming 101. Several second lifting points 4 are evenly spaced along the length of the main deck 102, below the hatch coaming 101. The distance between the second lifting points 4 and the assembly floor is 2.5 to 5 meters, and the distance from the bottom of the hatch coaming 101 is 0.6 to 1.6 meters. The width of the hatch coaming 101 is 1 to 2 meters. Therefore, for the first lifting points 3 located on the inner hull longitudinal wall 103, construction workers can simply climb up to the inner hull longitudinal wall 103 using a work ladder to directly hook the hooks. However, the several second lifting points 4 located below the hatch coaming 101 are obscured by the hatch coaming 101.

[0037] Therefore, the present invention proposes a method for using the segmented hanging connection of the shielding area, using the above-mentioned auxiliary tooling, specifically comprising the following steps:

[0038] S1. Lay the steel wire rope along the length of the bottom plate of the tooling body and secure it to the bottom plate of the tooling body through the fixing ears;

[0039] S2. The lug of the tooling body is connected to the crane hook, and the auxiliary tooling is lifted as a whole to the second lifting point of the torsion box segment;

[0040] S3. Connect one end of the steel wire connecting rope connected with the shackle to the second lifting point, and let the free end of the steel wire connecting rope hang to the ground for use;

[0041] S4. Remove the connection between the steel wire connecting rope and the fixing lug, and remove the workpiece body, which completes the fixing of the steel wire connecting rope of one of the second lifting points, as shown in Figure 5-6

[0042] S5. Repeat S1-S4 to sequentially complete the fixing of the steel wire connecting rope of all second lifting points of the torsion box section;

[0043] S6. According to the spacing between the second lifting points of the torsion box section, select the appropriate lifting row, and connect the steel wire rope of each sub-lifting point of the lifting row to the free end of the steel wire connecting rope fixed to each second lifting point through the shackle one by one, which completes the hanging connection of all second lifting points in the shielding area of the torsion box section, as shown in Figure 7-8

[0044] S7. Similarly, another crane hook is used to connect with several first lifting points on the torsion box section by using the lifting row, which completes the hanging connection between all lifting points for turning over of the torsion box section and the gantry crane, and the turning over of the torsion box section 1 is completed by controlling the movement track of the crane hook 5 located on both sides of the torsion box section 1, as shown in Figure 1

[0045] Further preferably, the lifting row 9 includes a lifting ring at the top and several sub-lifting points 901; the lifting row 9 is installed at the bottom of the crane hook 5 through the lifting ring, as shown in Figure 9 It is worth noting here that the spacing of the several sub-lifting points 901 can be adjusted according to the spacing between the lifting points to improve the adaptability.

[0046] In the process of turning over the torsion box section 1 of the container ship by using the traditional hook method, the construction personnel can climb to the inner shell longitudinal wall 103 by using the workpiece ladder to complete the hooking of the several first lifting points 3, but it is very difficult to hook the several second lifting points 4 on the shielding area below the hatch coaming 101 (the several second lifting points 4 are generally located about 1.7 m below the hatch coaming 101 from the top plate of the hatch coaming 101 and about 3.0 m from the ground of the total group), the construction personnel need to push the steel wire rope to hook, but the steel wire rope has a certain rigidity and is heavy, and at least 6 people are needed to complete the whole hooking process, of which 4 people cooperate to push the steel wire rope, and the other 2 people cooperate to connect the steel wire rope with the second lifting point 4 through the shackle 8, which is a large amount of work and time-consuming, and there is a safety hazard during installation.

[0047] ​​​But the method is adopted, first through auxiliary tool connects the steel wire connecting rope 7 with the second lifting point 4 (only needs 2 workers to stand on the both sides of auxiliary tool through tool ladder), then directly connects with the lifting row 9 under the crane hook 5 using the free end of steel wire connecting rope 7, no need to drag and move, can quickly and efficiently complete the lifting point hanging connection work of each shielding area.

For relevant researchers or technicians in the art, the specific meaning of the above terms in the present application can be determined according to the specific circumstances, and cannot be understood as a limitation of the present application.
