Description

TECHNICAL FIELD

[0001] The technical scheme relates to the ship production technical field, and particularly relates to a reverse support assembly. BACKGROUND

[0002] In the construction process of a ship and a marine engineering structure, due to the large size of the ship, it is difficult to carry out overall production and transportation, and therefore the ship body is usually divided into multiple independent ship body units so as to be manufactured and welded separately. However, during the welding process, the stress of the ship body units often changes due to temperature change, thereby causing deformation and resulting in misalignment or plate wall difference, that is, unevenness, which requires positioning operation during welding, such as positioning the gap and height between components such as bulb flat steel (ship beam), T-shaped material and ship plate.

[0003] For example, a green shipbuilding zero-code joint assembly special assembly tool and process is disclosed in Chinese Patent CN202110175850.5. The zero-code adjusting support seat in the patent comprises, from top to bottom, a leveling clamp for supporting a steel pipe, an adjusting screw and a joint adjusting base. During use, pressure is applied to the zero-code adjusting support seat through the steel pipe, the support seat is used to press down the ship plate and maintain it at a set position, thereby achieving the positioning of the plate joint and leveling to the set height.

[0004] However, the leveling clamp is supported at the lower end of the steel pipe, and it can only handle the situation of the protruding ship plate, that is, the leveling and positioning are achieved by pressing down the ship plate. However, when the ship plate is welded, the stress of the ship plate changes due to temperature change, thereby causing deformation and misalignment of the ship plate and resulting in plate wall difference, thereby causing the ship plate to be lower than the set height. At this time, an upward lifting force needs to be applied to the ship plate to maintain it at the set position. The existing leveling tool cannot complete the corresponding operation, resulting in limited use scenarios and inconvenience in use. SUMMARY

[0045] The specific embodiments of the technical solution will be further described in detail below in combination with the drawings.

[0046] As Figure 1 and Figure 2 A counter support assembly is used when the ship berth is closed, and after the profile and plate joint is flattened by using the codeless tool, the counter support assembly is added at the empty block of the two profiles to prevent the profile from deforming due to the stress change when the plate joint is welded, and the problem of the plate wall difference caused by the profile deformation, comprising:

[0047] The clamping mechanism 1 is used to be installed on the bulb flat steel 100 or T profile on the ship, so as to realize the installation and fixation of the clamping mechanism 1;

[0048] The connecting rod 2 is installed on the clamping mechanism 1;

[0049] Adjusting mechanism 3, one end of which is installed on connecting rod 2, and the other end is used to connect ship plate 200;

[0050] When clamping mechanism 1 is fixedly installed on the upper end of the bulb flat steel 100 or the T-shaped section of the ship, the ship plate 200 connected to the other end of the bulb flat steel 100 or the T-shaped section is positioned by the adjusting mechanism 3, so that the ship plate 200 is fixed at the set position, thereby ensuring that the plate joint of the ship plate 200 is flush during welding and the height of the ship plate joint is maintained at the set position;

[0051] In combination Figures 1-3 , the adjusting mechanism 3 comprises a connecting piece 4, a lifting assembly 5 and a code plate 6; the connecting piece 4 is provided with a mounting hole 41, the connecting piece 4 is sleeved on the connecting rod 2 through the mounting hole 41, the connecting piece 4 is installed on the connecting rod 2, the size and shape of the mounting hole 41 are matched with the size and shape of the connecting rod 2, so that the connecting rod 2 can be arranged in the mounting hole 41 without shaking in the mounting hole 41; the lifting assembly 5 is connected to the connecting piece 4 and the code plate 6 at both ends respectively, and the lifting assembly 5 has at least one driving end connected to at least one of the connecting piece 4 and the code plate 6, so that the lifting assembly 5 can drive the connecting piece 4 and the code plate 6 to approach or move away from each other; the code plate 6 is used for welding or abutting on the ship plate 200 to realize connection with the ship plate 200, and the code plate 6 is preferably welded together with the ship plate 200;

[0052] When the adjacent ship plates 200 are welded at high temperature, the stress at the welding position of the ship plate changes due to the temperature rise and fall, which causes deformation and misalignment and wall difference problems, so that the plate joint cannot be flush, and the height of the end of the ship plate 200 changes. The adjusting mechanism 3 of the technical solution can realize positioning operation of the ship plate 200, so that the ship plate 200 is maintained at the set height and position, avoiding the misalignment of the ship plate 200, thereby ensuring the welding effect.

[0053] In addition, the scheme of the present application can also be applied to the use scene of adjusting the height of the ship plate 200. When the ship plate 200 below the set height (i.e. both ship plates 200 are below the set height) is pulled up and leveled, the code plate 6 needs to be welded on the ship plate 200, the distance between the connecting piece 4 and the code plate 6 is adjusted by the lifting assembly 5, so that the distance between the connecting piece 4 and the code plate 6 is reduced, i.e. the connecting piece 4 approaches the code plate 6, thereby realizing the lifting of the ship plate 200 to the set height, i.e. realizing the reverse support operation of the bulb flat steel (i.e. the lifting operation), and at the same time, the plate joint of the adjacent ship plate 200 can be leveled and positioned to reach the production standard. After adjustment, the code plate 6 is cut off from the ship plate 200 by cutting operation.

[0054] When the ship plate 200 higher than the set height (i.e. both ship plates 200 are higher than the set height) is pressed down to be leveled, the spacer 6 is only needed to be abutted against the upper end of the ship plate 200, the distance between the connecting piece 4 and the spacer 6 is adjusted by the lifting assembly 5, so that the distance between the connecting piece 4 and the spacer 6 is increased, i.e. the connecting piece 4 is away from the spacer 6, so as to realize the operation of pressing down the ship plate 200 to the set height, i.e. the operation of supporting the bulb plate 100 (i.e. the operation of pressing down), and at the same time, the leveling and positioning of the butt joint between the adjacent ship plates 200 are realized, so as to reach the standard of production.

[0055] In combination with Figure 1 and Figure 7 , the end of the bulb plate 100 or the T-shaped profile is in the same plane with the end of the ship plate 200 or not, i.e. the butt joint between the adjacent ship plates 200 is in the same plane with the gap between the adjacent bulb plates 100 (or T-shaped profiles), the clamping mechanism 1 can be clamped and fixed on the upper end of the bulb plate 100 (or T-shaped profile), and the installation position of the clamping mechanism 1 is adjusted to adjust the connecting rod 2 to be located directly above the ship plate 200, and the spacer 6 is connected to the upper ends of the two adjacent ship plates 200 and can be located above the butt joint.

[0056] The technical solution is not limited to the positioning operation of the bulb plate, but can also be applied to other positioning operations in the field of shipbuilding, such as the positioning of the T-shaped profile of the ship, i.e. the clamping mechanism 1 is clamped and fixed on the T-shaped profile, and then the positioning operation of the ship plate 200 is performed to avoid the misalignment problem during welding.

[0057] As Figure 1 and Figure 2 , the axis of the connecting rod 2 is located in the projection of the ship plate 200 on the plane and coincides with the butt joint between the adjacent ship plates 200, when the lifting assembly 5 is adjusted, the adjusting mechanism 3 will exert a force on the connecting rod 2, and the connecting rod 2 will exert a counterforce on the adjusting mechanism 3, and the counterforce will be transmitted to the ship plate 200 through the spacer 6, and the use of the axis of the connecting rod 2 located in the projection of the ship plate 200 on the plane and coinciding with the butt joint between the adjacent ship plates 200 can ensure that the extension line of the counterforce exerted by the connecting rod 2 passes through the butt joint, so as to ensure that the force exerted by the spacer 6 on the ship plate 200 can be uniformly applied to the adjacent two ship plates 200, so as to ensure that the forces received by the adjacent two ship plates 200 are the same, thereby realizing the accurate and stable adjustment and maintenance of the adjacent two ship plates 200 at the same height.
