Description

Multi-purpose dry cargo ship lifting-off type cargo hold separation structure

Technical Field

The utility model relates to a multi-purpose dry cargo ship lift-off type cargo hold separation structure.

Background

The multipurpose dry cargo ship is mainly used for transporting sundry goods, ore sand, coal, cement, grains, wood and forest products, coil steel, heavy goods, large conventional bulk goods, containers or dangerous goods and other goods, generally has a load of thousands to tens of thousands of tons, and is a main ship type for branch transportation on water. To meet the demand for cargo diversity, multi-purpose dry cargo vessels are often provided with multiple sets of movable or fixed intermediate decks (also known as double decks) to horizontally or vertically divide the cargo hold into areas that can be reasonably utilized. Considering the factors of construction cost, dead weight, occupied space, loading and unloading convenience and the like, movable separation structures, particularly hanging-off type cargo compartment separation structures, are adopted in the industry at present.

As shown in fig. 1 to 3, the conventional cargo compartment separation structure of a lift-off type includes an intermediate deck 101, and a supporting device 102 and a bolt limiting device used in cooperation with the intermediate deck 101, wherein when the intermediate deck 101 needs to be horizontally placed to separate the cargo compartment into upper and lower levels, the edges of the intermediate deck 101 are placed on a plurality of supporting devices 102 horizontally spaced apart from each other on the longitudinal walls of the cargo compartment, so that a large vertical load can be borne and distributed on the supporting devices 102; when the middle deck 101 needs to be vertically placed to divide the cargo hold into a plurality of cargo hold sections, the bolts 103 on the edge part of the middle deck 101 are limited through a plurality of bolt holes arranged at intervals on the longitudinal bulkhead of the cargo hold, so that the load is dispersed on the bolt limiting device; in addition, a plurality of recessed lashing eye rings 104 for lashing goods in the cargo hold are arranged on the longitudinal bulkhead of the cargo hold at intervals. However, in the existing hanging-off cargo compartment separation structure, the number of the supporting devices 102 and the number of the bolt limiting devices are large, the system is complicated, the reliability of the middle deck 101 for bearing the cargo is affected, the bolt holes and the binding eye rings 104 are large in number and size, and the holes are formed in the bulkhead, so that watertight reinforcement treatment needs to be performed on each hole, the integrity and the continuity of the bulkhead and the strengthening materials thereof are affected, and meanwhile, the bulkhead is cleaned after unloading is troublesome due to the fact that the holes are formed in the bulkhead; in addition, due to the special structure of the existing hanging-off type cargo hold separation structure, when the middle deck 101 is installed, a crewman needs to enter the cargo hold by using a hanging basket, and manually place the supporting device 102 or pull the bolt 103 to insert into the bolt hole for limiting, however, each supporting device 102 and the bolt 103 weigh more than one hundred kilograms, and multiple crewmans need to cooperate to operate, so that the labor intensity is high, the operation time is long, and the safety is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a multipurpose dry cargo ship hanging-off type cargo hold separation structure integrating limiting and supporting, which has the advantages of simple structure, convenience in installation, safety and reliability in work, high working efficiency, low cost and easiness in maintenance.

The utility model relates to a multi-purpose dry cargo ship lift-off type cargo compartment separation structure, which comprises a plurality of supporting flat steels and a middle deck, wherein the supporting flat steels are vertically and horizontally connected to a bulkhead of a cargo compartment at intervals; when the middle deck is horizontally placed, the concave surface of the edge part of the middle deck is arranged at the top end of the supporting flat steel, and when the middle deck is vertically placed, the groove of the edge part of the middle deck is clamped on the supporting flat steel from top to bottom.

According to the multi-purpose dry cargo ship lift-off type cargo compartment separation structure, the horizontal placement and the vertical placement of the middle deck are realized through the matching of the concave surface on the middle deck and the top end of the support flat steel and the matching of the groove on the middle deck and the support flat steel, so that cargo compartments are separated according to the requirement, and the number of the middle decks is set according to the actual requirement; the concave surface is trapezoidal, so that when the middle deck is horizontally placed, two oblique side edges of the trapezoid are matched with the top end of the support flat steel to limit the displacement of the middle deck, and meanwhile, when the middle deck is vertically placed, the groove on the middle deck is clamped on the support flat steel from top to bottom and can also limit the displacement of the middle deck; by adopting the structure, a crew can be prevented from entering the cargo hold, the intermediate deck can be placed only by hoisting the intermediate deck to align the concave surface on the intermediate deck with the top end of the support flat steel or align the groove on the intermediate deck with the support flat steel, and the device is convenient to operate, safe and reliable in work and high in work efficiency; in addition, the opening of the bulkhead of the cargo hold is avoided, so that the cargo hold can be cleaned conveniently after unloading, meanwhile, the reinforcement and watertight treatment of the opening is also avoided, and the maintenance cost is low; the support flat steel is directly connected to the bulkhead of the cargo hold, so that when heavy goods are loaded, the support flat steel can be prevented from directly colliding with the bulkhead, and the effect of protective materials on the bulkhead of the cargo hold is achieved.

Detailed Description

A multipurpose dry cargo ship lift-off type cargo compartment separation structure comprises a plurality of supporting flat steels 1 and an intermediate deck 2, wherein the supporting flat steels 1 are connected to a bulkhead of a cargo compartment in a vertical state at intervals horizontally, a groove 3 is formed in the edge of the intermediate deck 2, and a trapezoidal concave surface 4 is formed in the bottom surface of the edge of the intermediate deck 2; when the middle deck 2 is horizontally placed, the concave surface 4 of the edge part is arranged at the top end of the supporting flat steel 1, and when the middle deck 2 is vertically placed, the groove 3 of the edge part is clamped on the supporting flat steel 1 from top to bottom. The support flat steel 1 is connected with the bulkhead of the cargo hold in a welding mode, and is firm in connection and high in strength.

The supporting flat steel 1 is thick at both ends and thin in the middle, or is in a state of uniform thickness. Wherein, when the supporting flat steel 1 is in a state of being thick at both ends and thin in the middle, the weight of the partition structure can be reduced.
