Description

Technical Field

[0001] This invention belongs to the field of marine engineering replenishment technology, specifically a dry-liquid cargo shared replenishment gantry. Background Technology

[0002] At-sea replenishment is a comprehensive, high-tech operation integrating shipbuilding engineering, mechanical automation, navigation technology, and personnel collaboration. It is an important indicator of a nation's shipping technology support capabilities for long-range maritime operations. Common replenishment systems include two different replenishment units: dry cargo replenishment units and liquid cargo replenishment units. Each unit uses its own gantry, which significantly occupies deck space.

[0003] Existing related patent technologies, such as patent document (CN107554704A), disclose an integrated marine replenishment system. One of its objectives is to solve the problem of integrated marine replenishment systems occupying a large amount of deck space. However, its solution still has space occupancy issues: although the system integrates dry cargo and liquid cargo replenishment systems onto a single gantry, multiple winch devices (dry cargo overhead cable winch, liquid cargo overhead cable winch, lifting winch, external traction cable winch, internal traction cable winch, traction winch, etc.) still need to be installed on the deck. These winches are scattered in different locations on the deck, occupying a large amount of deck working space. The two column structures and their bottom installation area also require a large amount of deck space; and it is impossible to achieve… The current method for rapid dry-to-liquid cargo switching involves several steps. First, when switching from dry cargo replenishment to liquid cargo replenishment, the end of the dry cargo overhead cable connected to the receiving ship needs to be retracted to the lifting pulley device. The cargo transfer trolley then stops at the lifting pulley device, which descends along the length of the column. Second, when switching from liquid cargo replenishment to dry cargo replenishment, the end of the liquid cargo overhead cable connecting to the receiving ship needs to be retracted to the liquid cargo overhead cable pulley via a liquid cargo overhead cable winch. The pipeline trolley then stops at the liquid cargo overhead cable pulley. This series of operations is time-consuming in the complex maritime environment, making it unsuitable for emergency replenishment needs. Each switch requires readjusting the equipment, reducing replenishment efficiency. Furthermore, the replenishment process is lengthy and maintenance costs are high. Therefore, while this patent addresses the issue of traditional systems occupying deck space to some extent, it still has significant shortcomings in terms of rapid dry-to-liquid cargo switching, replenishment efficiency, and maintenance costs, making it difficult to meet the demand for high-efficiency, multi-functional maritime replenishment.

[0004] Therefore, it is necessary to develop an integrated dry and liquid cargo replenishment device to improve replenishment efficiency and deck space utilization. Summary of the Invention

[0005] The present invention provides a shared dry and liquid cargo replenishment gantry to solve the following technical problems: 1. Traditional at-sea replenishment involves two separate systems for dry and liquid cargo transport, each requiring a dedicated gantry, which occupies significant deck space. Furthermore, these two gantry systems necessitate two control systems and two operational teams, demanding redundant human and material resources. The design, construction, and maintenance costs are also relatively high.

[0006] 2. The fundamental purpose of this invention is to integrate the structural foundation, support points, and operating space of the two systems into one through high integration, thereby achieving "one machine for multiple uses". This greatly saves the deck area, makes the ship design layout more compact, significantly improves the efficiency and flexibility of replenishment, reduces life cycle costs, and reduces labor intensity.

[0007] The technical solution adopted by this invention to solve the technical problem is: a marine dry and liquid cargo replenishment gantry, including a gantry body, a top platform, bases for various components, internal guide rails, and a liquid cargo support. The top platform is provided on the top of the gantry body for dry cargo delivery and replenishment; the liquid cargo support is provided below the top platform for liquid cargo delivery and replenishment. The structural foundation, support points, and operating space of the two systems for dry cargo delivery and replenishment and liquid cargo delivery and replenishment are combined into one, realizing "one machine for multiple uses", saving deck space and improving replenishment efficiency and flexibility.

[0008] Furthermore, a steel cable base, a base one, and a base two are provided above the top platform; a base three and a base five are provided below the top platform.

[0009] Furthermore, a cable anti-loosening device is fixed to the top of the liquid cargo support, which is used to maintain the tension of the cable after it is laid.

[0010] Furthermore, base four and base six are installed at the bottom of the liquid cargo support.

[0011] Furthermore, two maintenance platforms and ladders are installed on the gantry body.

[0012] Furthermore, guardrails are installed on the outside of the ladder to protect the operators.

[0013] Furthermore, the gantry body is equipped with a skin structure to protect the gantry body.

[0014] Furthermore, an internal guide rail is provided in the middle of the gantry body, with a lower guide sprocket at the bottom of the internal guide rail and a base seven at the top of the internal guide rail. The base seven works in conjunction with the lower guide sprocket to achieve position guidance.

[0015] Furthermore, anti-rotation guide rails are also installed on the gantry body to enhance the strength of the connection and fixation.

[0016] Compared with the prior art, the present invention has the following significant advantages: This invention integrates the structural foundation, support points, and operating space of two systems into one through high integration, achieving "one machine for multiple uses". This greatly saves deck space, makes the ship design layout more compact, significantly improves the efficiency and flexibility of replenishment, reduces life cycle costs, and reduces labor intensity.

[0017] This invention achieves one-stop replenishment, optimizes space utilization, greatly simplifies the operation process, and improves replenishment efficiency through high integration. Attached Figure Description
