Description

Technical Field

[0001] This invention relates to a marine replenishment test platform, specifically a heavy dry liquid cargo delivery test rig. Background Technology

[0002] At-sea replenishment is the lifeline of ocean shipping. Highly complex sea conditions are typically accompanied by high risks, high costs, and non-repeatability. The core objective of an at-sea replenishment test platform is to simulate the real-world environment and process of at-sea replenishment, either on land or in controlled waters, for technology development, equipment testing, and personnel training. The test platform integrates multiple technologies, including marine environment simulation technology, high-precision measurement and sensing technology, and mechanical and control systems. Traditional test platforms typically use two simple simulated benches for basic principle verification, while modern integrated platforms require comprehensive, high-fidelity, human-enclosed integrated testing to meet safety, efficiency, and cost-effectiveness requirements.

[0003] Among existing related patent technologies, such as the support device for a test bench in a civil aircraft fuel testing laboratory disclosed in patent document (CN208882130U), this patent is specifically designed for civil aircraft fuel testing laboratories. This design is completely unsuitable for the delivery scenario of heavy dry liquid cargo. The main structure of the support frame is only welded from square steel, and its structural strength and load-bearing capacity are designed for test fuel tanks, not for heavy dry liquid cargo. It cannot meet the load-bearing requirements of heavy cargo, and lacks a test installation platform and various fixing structures. It cannot be used for heavy dry liquid cargo delivery tests or at-sea replenishment simulations, and has fundamental technical limitations and functional deficiencies, failing to meet the technical requirements of related tests.

[0004] Therefore, there is an urgent need to design a test platform specifically designed for the marine environment, with heavy cargo handling capabilities and real sea condition simulation functions. Summary of the Invention

[0005] The present invention provides a heavy-duty dry liquid cargo delivery test bench to solve the following technical problems: 1. The test bench should be able to simulate and reproduce marine operating conditions, including ocean disturbances, deck space constraints, high tension control, etc., to simulate the operating environment of the launching vessel and verify the safety of the launching device.

[0006] 2. The test bench should be able to simultaneously simulate the dispatching of dry and liquid goods, enabling operator-in-the-loop simulation and synchronous acquisition of test data.

[0007] The technical solution adopted by the present invention to solve the technical problem is: a heavy-duty dry and liquid cargo delivery test bench, including a support base, a platform panel, a connecting seat structure, a pulley seat structure, and an inclined pulley seat structure. The platform panel is fixedly connected to the support base, and multiple pulley seat structures and inclined pulley seat structures are fixedly connected to the platform panel. The platform panel is also provided with three square holes, wherein the largest square hole is used to install the actuator of the dry cargo delivery device, the medium square hole is used to install the actuator of the liquid cargo delivery device, and the smallest square hole is used to install the anti-loosening device.

[0008] Furthermore, the support base includes a main beam, a secondary beam, a secondary beam, a column, and a cross brace. The main beam is fixed to the top of the column, and the secondary beam is installed between the main beams to connect them.

[0009] Furthermore, horizontal braces are fixed parallel to each other between the columns to improve the stability of the columns.

[0010] Furthermore, the secondary beam is installed below the largest square hole and perpendicular to the main beam to improve the structural rigidity of the platform.

[0011] Furthermore, the two pulley seat structural components are respectively fixed to the sub-beam by four lower sealing plates.

[0012] Furthermore, a connecting seat structure is installed on the side wall of the smallest square hole on the platform panel to fix the anti-loosening device.

[0013] Furthermore, the platform panel is fixed to the top of the main beam and the secondary beam, and a platform fixing connection plate is installed on the platform panel.

[0014] Furthermore, the bottom of the platform fixed connection plate and the two pulley seat structural components are fixedly connected to the sealing plate reinforcement plate, and the sealing plate reinforcement plate is fixedly connected to the sub-beam.

[0015] Furthermore, a ladder is fixedly connected to the platform panel, and guardrails are installed on both the ladder and the platform panel.

[0016] Furthermore, during the test installation, the anti-loosening actuator of the dry cargo dispensing device is installed in the largest square hole pre-reserved on the test bench, and the anti-loosening actuator of the liquid cargo dispensing device is installed in the medium square hole pre-reserved on the test bench. The inner traction cable of the dry cargo dispensing device is connected to the inner traction cable winch arranged below the test bench through the guide pulley installed on the pulley seat structure component two and the through-deck pulley installed on the pulley seat structure component one. The outer traction cable of the dry cargo dispensing device is connected to the spring tensioning device installed on the platform fixed connection plate and the pulley seat structure component one. The deck pulley on the upper part is connected to the outer traction winch arranged below the test bench. The overhead cable passes through the anti-loosening actuating cylinder of the dry cargo delivery device and is connected to the overhead cable winch arranged below the test bench. The inner, middle and outer saddle cables of the liquid cargo delivery device are connected to the inner, middle and outer saddle cable winches arranged below the test bench through the inclined guide pulley on the inclined pulley seat structure and the deck pulley on the pulley seat structure. The outer saddle cable is also connected to the outer saddle cable winch through the anti-loosening device installed on the connecting seat structure.

[0017] Compared with the prior art, the present invention has the following significant advantages: By integrating dry-liquid cargo delivery components onto a single test bench, simulating the operational status of the dry-liquid cargo delivery unit on a replenishment ship, and allowing for direct welding and fixing to the replenishment equipment, replenishment-related tests can be conducted. This approach enables the early detection of design flaws or operational errors, facilitates the refinement of operational procedures, reduces equipment wear and tear, and optimizes resource allocation. It also lowers testing costs, verifies the feasibility of technical approaches, refines parameters, and improves the stability and efficiency of production deployment. Attached Figure Description
