Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, and specifically relates to an auxiliary tooling component for underwater side entry of ship equipment. Background Technology

[0002] Since 2022, with the recovery of the shipbuilding industry, major shipyards have been operating at full capacity. This high workload has resulted in a low tolerance for production cycle errors. Due to tight order schedules, shipyards have virtually no leeway in dock or slipway time. According to shipbuilding practice, all equipment must be installed in the dock before launching, and dockside construction is relatively convenient. However, with virtually no leeway in the dock, delays in the delivery of individual pieces of equipment affecting the overall launching time are economically unacceptable. Therefore, to improve the tolerance for errors in the shipbuilding cycle, major shipyards have begun exploring the feasibility of underwater equipment installation. The normal equipment installation method involves vertical lifting, followed by pulling and positioning. However, with underwater installation, since the superstructure is mostly completed and the main equipment is concentrated in the engine room area, vertical lifting would require drilling multiple layers of process holes, causing significant damage to the hull integrity and requiring substantial post-installation restoration work. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an auxiliary tooling assembly for underwater side entry of ship equipment into the cabin.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary tooling assembly for underwater side entry of ship equipment includes a temporary base, a tooling transfer platform, a transfer track, and multiple transfer lifting brackets. The multiple transfer lifting brackets are spaced apart inside the ship along a transfer path. The transfer track extends from the outside of the equipment entry process hole along the equipment transfer path to the equipment installation position. In use, the ship equipment is placed on the temporary base, the temporary base is placed on the tooling transfer platform, the tooling transfer platform is hoisted to the transfer track located outside the hull, and the temporary base carrying the ship equipment is transferred along the transfer track to the equipment installation position and fixedly installed using the transfer lifting brackets.

[0005] Furthermore, the temporary base includes two spaced and mirror-symmetrically arranged right-angled U-shaped beams, with the bottom plates of the two right-angled U-shaped beams facing each other, and the two right-angled U-shaped beams are connected by multiple reinforcing flat irons; multiple base lifting brackets are mirror-symmetrically arranged on the two right-angled U-shaped beams.

[0006] Furthermore, each of the right-angled U-shaped beams has two base lifting brackets, one end of which is fixed to the inner cavity of the right-angled U-shaped beam, and the lifting end extends out of the right-angled U-shaped beam.

[0007] Furthermore, multiple reinforcing plates are spaced apart in the inner cavity of each right-angled U-shaped beam, and the multiple reinforcing plates are located between the two base lifting brackets.

[0008] Furthermore, the tooling transfer platform includes a base, with guardrails on three sides of the upper surface of the base, and multiple platform lifting brackets symmetrically arranged on the two opposite outer surfaces, each equipped with the guardrails.

[0009] Furthermore, the transfer track extends 2-3 meters beyond the entry process hole at one end located outside the entry process hole.

[0010] The auxiliary tooling components for underwater side entry of ship equipment using this utility model can achieve the requirement of equipment entering the cabin while having a small impact on the overall ship construction cycle and almost no impact on the progress of the entire ship construction. Moreover, the construction difficulty is relatively small, and it has high promotional value. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1-3 As shown, an auxiliary tooling assembly for underwater side entry of ship equipment includes a temporary base, a tooling transfer platform, a transfer track 8, and multiple transfer lifting weights 9. The multiple transfer lifting weights 9 are spaced apart inside the ship along the transfer path. The transfer track 8 extends from the outside of the equipment entry process hole along the equipment transfer path to the equipment installation position. In use, the ship equipment is placed on the temporary base, the temporary base is placed on the tooling transfer platform, the tooling transfer platform is hoisted to the transfer track 8 located on the outside of the hull, and the temporary base carrying the ship equipment is transferred along the transfer track 8 using the transfer lifting weights 9 to the equipment installation position and fixedly installed.

[0017] Preferably, the transfer track 8 extends 2-3 meters beyond the entry process hole at one end located outside the entry process hole.

[0018] Specifically, the temporary base includes two spaced and mirror-symmetrically arranged right-angled U-shaped beams 5, with the base plates of the two right-angled U-shaped beams 5 facing each other, and the two right-angled U-shaped beams 5 connected by multiple reinforcing flat irons 6; two base lifting brackets 4 are mirror-symmetrically arranged on the two right-angled U-shaped beams 5, one end of the base lifting bracket 4 is fixed to the inner cavity of the right-angled U-shaped beam 5, and the lifting end extends out of the right-angled U-shaped beam 5.

[0019] In order to ensure that the temporary base structure is strong enough to support the ship equipment, in some embodiments, multiple reinforcing plates 7 are provided at intervals in the inner cavity of each right-angled U-shaped beam 5, and the multiple reinforcing plates 7 are located between two base lifting brackets 4.

[0020] Specifically, the tooling transfer platform includes a base 2, with guardrails 1 on three sides of the upper surface of the base 2, and multiple platform lifting brackets 3 symmetrically arranged on the two opposite outer surfaces on which the guardrails 1 are provided.

[0021] The method for underwater entry of ship equipment into the cabin using the auxiliary tooling for underwater side entry of ship equipment described in this utility model specifically includes the following steps: Step 1: Complete the construction of the temporary base and tooling transfer platform according to the preliminary planning scheme; Step 2: Pre-install the ship's equipment onto the temporary base. Before dismantling the temporary base, all hoisting operations should prioritize hoisting the lifting points on the temporary base. Step 3: The assembled ship equipment and temporary base are hoisted onto the tooling transfer platform, with the center of gravity of the ship equipment controlled between the front and rear hoisting points.

[0022] Step 4: Lay transfer track 8 in advance on the ship's equipment transfer path. Transfer track 8 is made of 114*8 round pipe.

[0023] Step 5: Arrange the transfer crane 9 and the final vertical placement crane in appropriate positions on the ship in advance.

[0024] Step 6: Use a floating crane to lift the tooling transfer platform and send it to the process hole position on the hull. Pay attention to the lifting direction. The side of the tooling transfer platform without railings should first be close to the hull.

[0025] Step 7: Position the tooling transfer platform, weld the clamps or spot weld the platform on site for simple fixation to prevent shaking.

[0026] Step 8: On-site construction personnel take safety precautions and pull the equipment from the transfer platform into the main hull, completing the equipment loading process.

[0027] Step 9: Using the previously set transfer hooks 9 and transfer rails 8, pull the temporary base to the temporary base and send the ship equipment with a longer journey to the ship equipment hoisting position.

[0028] Step 10: Remove the temporary base, use the previously set vertical positioning clamps to hoist the ship's equipment, and place it in the hull where the equipment is located.

[0029] Step 11: Move the ship equipment with the closest travel distance to the vicinity of the ship equipment lifting port, remove the temporary base, remove the transfer track 8 above the ship equipment lifting port, use the previously set vertical positioning lifting weights to lift the ship equipment and place it in the hull position where the equipment is located.
