[0002] Lifting demoulding is an important step in the production process of FRP hull. Its principle is to use the force generated by the lifting system to safely and completely remove the solidified FRP hull from the mold. Lifting demoulding can ensure that the hull is not damaged during the demoulding process and maintain the integrity of the basic appearance and structure.

[0003] In the past, the fiberglass hull was directly lifted by supporting ropes at the bottom of the hull. During the lifting process, the ropes might wear the hull, or the lifting and fixing force might be uneven, resulting in partial breakage of the lifted part.

[0004] Therefore, according to the above technical problems, this application adopts a lifting device that can pass through the bottom of the hull through a flexible laminated glass steel, and cooperate with the hull to complete demoulding and transportation. The flexible laminated end surface can prevent the hull from being damaged by excessive friction on the bottom end surface of the fiberglass hull, or from being broken due to uneven local force. The built-in flexible laminated fabric and the raised part of the bottom of the middle section that fits the bottom of the ship can effectively play the role of buffering the hull. At the same time, the fabric can be extended according to different ship types, and it has strong adaptability. Summary of the invention

[0007] Furthermore, the bottom support plate is formed integrally with the side support and the bottom support, and chamfered structures are left at the corners of the side support and the bottom support.

[0008] Furthermore, the top end surface of the bottom support plate is connected with a wear-resistant coating via an adhesive layer.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0020] like Figure 1 and Figure 2As shown, a fiberglass hull lifting and demoulding equipment includes a bottom support plate; the upper end surface of the bottom support plate 14 is an arc-shaped supporting structure, the upper end surface of the bottom support plate 14 is in lifting contact with the bottom of the hull, the left and right sides of the bottom support plate 14 are transversely provided with belt holes, and the belt holes are transversely inserted with slings 4, the slings 4 extending along the two sides of the bottom support plate 14 are connected to the sling blocks 10, and the sides of the sling blocks 10 are connected with sling chains through auxiliary pipes 12. Among them, the arc-shaped supporting structure on the upper end surface of the bottom support plate 14 can cooperate with lifting the hull, the left and right sides of the bottom support plate 14 are transversely provided with belt holes, the belt holes can cooperate with storing the slings 4, the flexible fitting end surface of the slings 4 is in flexible contact with the bottom of the bottom of the ship, and can effectively protect the bottom end surface of the hull from damage. The sling block 10 is responsible for limiting the extension length of the slings 4, and can also cooperate with the sling chain for lifting.

[0021] like Figure 1 and Figure 2 As shown, the bottom support plate 14 is formed integrally by the side support 1 and the bottom support 5, and a chamfered structure is left at the corners of the side support 1 and the bottom support 5. The side support 1 and the bottom support 5 are respectively matched with the side and bottom of the hull to increase the lifting contact area, thereby ensuring uniform loading and lifting force.

[0022] like Figure 1 and Figure 2 As shown, the top end surface of the bottom support plate 14 is connected with a wear-resistant coating 2 through an adhesive layer 7. The design of the wear-resistant coating 2 can effectively extend the service life of the top end surface of the bottom support plate 14.

[0023] like Figure 1 and Figure 2 As shown, the bottom support plate 14 is provided with deformation sockets 6 at the front and rear, and the deformation sockets 6 are filled with a foam filling layer 9. The foam filling layer 9 filled in the deformation socket 6 can cooperate with extrusion buffering to eliminate internal stress.

Since the chain hole 13 needs to be connected to the mounting chain, it will be subject to corresponding wear, so the normal operation of the equipment can be ensured by replacing the auxiliary tube 12 to adapt to the chain hole 13.

[0025] The outer ring of the jack is encapsulated with a sealing ring 11. The sealing ring 11 serves as a filling structure to prevent temperature changes from affecting the tightness of the auxiliary pipe 12 and the mounting block 10, thereby ensuring the safety of the mounting.

[0026] like Figure 1 and Figure 2As shown, a balance pad 8 is installed on the sling 4 between the two sets of bottom support plates 14. The balance pad 8 is located at the center of the sling 4. The top end surface of the balance pad 8 is a "V"-shaped pad groove 3. The "V"-shaped pad groove 3 is in contact with the raised part of the bottom end surface of the hull. The balance pad 8 cooperates with the V"-shaped pad groove 3 to accurately lift the raised part of the bottom of the glass hull, thereby ensuring more accurate force.
