Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, in particular to an impact-resistant liquid tank sliding saddle. Background Art

[0002] At present, in the field of new-built dual-fuel shipbuilding, the installation of liquid cargo tanks is a key and difficult project in the construction process. Among them, the cargo tank is a rigid body. According to the material characteristics, the installation process will be troubled by the phenomenon of thermal expansion and contraction. Especially after rigid contact with the hull, the friction requirements for the contact surface are correspondingly increased. If there is a slight mistake, it will cause damage to the tank body and the hull, and even cause the ship to capsize due to the installation deformation of the tank body.

[0003] Currently, most of the installations of liquid cargo tanks at home and abroad are still mainly based on rigid contact. Even at the sliding end, high-strength rigid materials are selected as sliding sheets, which is extremely disadvantageous for the long-term use of liquid cargo tanks. When the weather changes, the tank body will deform, thus increasing the friction of rigid contact. Over time, it will cause damage to the hull and the tank body. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides an impact-resistant liquid tank sliding saddle, which has flexible contact, increases the wear resistance coefficient of the base device, protects the tank body and the hull from damage, and offsets the impact of hull deformation on the tank body.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0006] An impact-resistant liquid tank sliding saddle, comprising a base log, a base connecting device and a steel baffle. The steel baffle is fixed on the four peripheral sides of the top surface of the hull saddle, and the base log is flexibly connected to the hull saddle through the base connecting device.

[0007] Further, the base connecting device includes a flexible gasket and a base epoxy resin layer. The flexible gasket is laid on the top surface of the hull saddle, inside the steel baffle, and the base log is fixed on the upper surface of the flexible gasket through the epoxy base resin layer.

[0008] Further, the longitudinal section of the base epoxy resin layer is U-shaped, and the base log is embedded and fixed in the epoxy resin layer.

[0009] Further, a sponge pad enclosure is covered on the outer peripheral side of the epoxy resin layer.

[0010] Further, the width of the sponge pad enclosure is smaller than the width of the hull base.

[0011] Further, the flexible gasket is closely laid on the hull saddle through sponge strips and glass adhesive tapes.

[0012] The anti-impact liquid tank sliding saddle of the present utility model avoids the rigid contact between the cargo tank and the hull, reduces the impact force of the hull on the tank body, protects the tank body from deformation damage and wear of the base surface. By using the flexible device, the anti-impact performance of the cargo tank base is improved as a whole, the friction damage rate of the contact surface is reduced, and the device of the present invention can extend the service life of the liquid cargo tank base, playing a protective role for the hull and the tank body.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0017] As Figure 1 shown, an anti-impact liquid tank sliding saddle includes a base sunken wood 1, a base connecting device and a steel retaining piece 3. The steel retaining piece 3 is fixed on the four peripheral sides of the top surface of the hull saddle 4, and the base sunken wood 1 is flexibly connected to the hull saddle 4 through the base connecting device.

[0018] The base connecting device includes a flexible gasket 2 and a base epoxy resin layer 5. The flexible gasket 2 is laid on the top surface of the hull saddle 4. The flexible gasket 2 is closely laid on the hull saddle 4 through sponge strips and glass adhesive tapes. The flexible gasket 2 is located inside the steel retaining piece 3, and the base sunken wood 1 is fixed on the upper surface of the flexible gasket 2 through the epoxy base resin layer.

[0019] Further, the longitudinal section of the base epoxy resin layer 5 is U-shaped, and the base sunken wood 1 is embedded and fixed in the epoxy resin layer.

[0020] Further, a sponge pad enclosure 6 is covered on the outer peripheral side of the base epoxy resin layer 5, and the width of the sponge pad enclosure 6 is smaller than the width of the hull base.

[0021] After the hull base of the liquid cargo tank is built, the tank needs to be hoisted. To protect the liquid cargo tank, the usual practice is to have one end as a fixed end and the other end as a sliding end. Such a method can bear the expansion and contraction change amount of the cargo tank itself and protect the tank installation. However, the cross-section of the liquid cargo tank is a curved surface. Therefore, in the actual construction process, due to engineering errors, the contact surface between the tank and the hull saddle 4 cannot be completely fitted. A base device will be added between the liquid cargo tank and the hull saddle 4 to better bear and fix the liquid cargo tank. The manufacturing method of the impact-resistant liquid tank sliding saddle described in the present utility model specifically includes the following steps:

[0022] 1) Process the railing of the sliding saddle, and weld the steel shim 3 on the edge of the saddle;

[0023] 2) Clean the saddle surface at the sliding end of the hull. After cleaning, lay a flexible soft pad 2. Select PTFE as the base material and lay it on the saddle surface with a thickness between 1 and 5 mm. It is necessary to ensure that the base surface of the liquid cargo tank is at the same height. In addition, select a PTFE gasket with a slightly thicker coating, which can have better ductility and tensile strength and optimize the friction performance of the base surface;

[0024] 3) After laying the flexible soft pad 2, shape and fix it along the edge of the hull saddle 4. Use a sponge strip and glass adhesive tape to closely pad the saddle. The outside of the sponge strip is flush with the edge of the saddle. Make the thickness h of the sponge strip. The sponge strip should be as thick as possible to ensure the resilience of the sponge strip, and use glass adhesive tape to tie the sponge strip tightly. Then use the customized tooling part 7 to fix it, evenly distributed, to fix the sponge strip. The tooling part 7 is adjustable. One side of the customized tooling part buckles the sponge strip, and the other side uses adjustable screws to fix it on the saddle floor;

[0025] 4) After fixing the sponge strip and the flexible gasket 2, cut the flexible gasket 2. Cut the part of the flexible soft pad 2 that conflicts with the steel shim. The trimmed edge should be smooth and flush, and no burrs are allowed. After trimming, place plasticine equidistantly on the flexible gasket 2. The height of the plasticine needs to be the same. After the plasticine is placed, cover and protect it to facilitate the subsequent gap measurement, determine the thickness of the epoxy resin pouring, and level the installation of the tank seat;

[0026] 5) Hoist and press the liquid cargo tank. During the pressing process, control the lifting hook well and do not allow the liquid cargo tank to be unhooked from the crane to avoid damage to the tank device. At the same time, protect the flexible soft pad 2 and the surrounding shaped retaining strips;

[0027] 6) During the pressing process, measure the horizontal distance between the liquid cargo tank and the saddle retaining strip to ensure good contact during the later pouring and avoid uneven pouring of the liquid cargo tank base;

[0028] 7) After the film pressing is completed, lift the cargo tank again. The lifting height should ensure that construction workers have enough space to pour the measurement base, which can save working hours. Measure the thickness of the modeling clay, record the values and orientations, and calculate the pouring thickness. Pour epoxy resin into the base of the liquid cargo tank body. During the pouring process, use wooden strips to block and prevent the liquid epoxy resin from flowing. After waiting for a period of time, after the epoxy resin and the flexible gasket 2 are formed, they are molded into one body with the base surface of the liquid cargo tank body, bearing the weight of the liquid cargo tank, connecting the deformation and expansion amount of the tank body, and protecting the safety of the tank body.
