Embodiment Construction

[0016] A steel plate loading and unloading operation method for ships with small hatches, which uses special hook chains to replace the steel plate spreader used in conventional steel plate operations, and adopts the hoisting method of eccentric lashing cables, so that the steel plate surface and the horizontal plane form an angle after the steel plate is hoisted. At this time, the lower side of the steel plate is first to enter the hatch along the diagonal direction of the hatch, and then hooked along the trend to place the steel plate firmly in the cabin.

[0017] Such as figure 1 The special hook chain shown is: a wire rope sling 2 with a ring-shaped suspension nose 1 at both ends, one end of the chain 4 is connected to the ring-shaped suspension nose at one end, the other end of the chain is connected to the end ring 5, and there is a Sliding hook 3 that can move freely.

[0018] In response to this situation, according to the structural characteristics of the cabin and t...

Abstract

The invention discloses a method for loading and unloading a steel plate of a small-hatch ship. The method comprises the following steps: replacing a steel plate hanger used in conventional steel plate operation by a special hook chain; using an eccentric rope to lift the steel plate to ensure that an angle is formed between the steel plate surface and the horizontal plane; and when shipping, leading one lower side of the steel plate into the hatch along the diagonal direction of the hatch and hooking the steel plate so as to stably place the steel plate in the hatch. The special hook chain isa wire rope sling of which the two ends are provided with annular hanging noses, wherein the annular hanging nose at one end is connected with one end of a chain, and the other end of the chain is connected with an end ring; and the chain is provided with a sliding hook capable of moving freely. The method for loading and unloading a steel plate of a small-hatch ship has the advantages that: thetechnique for shipping the steel plate of the small-hatch ship fills a blank in the aspect of loading technique for the company. After being implemented, the technique achieves good economic performance and social benefit.

Description

technical field [0001] The invention belongs to a port cargo loading and unloading method, in particular to a small hatch ship steel plate loading and unloading operation method. Background technique [0002] In port loading and unloading operations, in order to ensure the safety, quality and efficiency of steel plate loading and unloading ship operations, the conventional operation process plan for steel plate operations: use special steel plate spreaders (composed of special support bars, special steel plate clamps, etc.) It is in a horizontal state during loading and unloading to prevent the steel plate from decoupling and falling due to accidental shaking or bumping. figure 1 It is a schematic diagram of hoisting for conventional steel plate operations. [0003] For ships with small hatches, the hatch size is equal to or slightly smaller than the length of the stowage steel plate (the length of the stowage steel plate is generally about 6 meters). In this case, the loa...
