Description

TECHNICAL FIELD

[0001] The utility model relates to ship auxiliary construction technical field, concretely relates to a kind of protective tooling suitable for ship outer plate pipeline operation. BACKGROUND

[0002] At present, shipyard needs to pull and place dynamic energy pipeline, such as power line, oxygen pipeline, natural gas pipeline, CO2 pipeline or air pipeline, in loading stage and wharf stage. These pipelines are close to ship outer plate, which will hinder ship outer plate coating spraying operation. After ship outer plate painting operation is completed, the dynamic energy pipeline erected will also damage the coating of ship outer plate. Therefore, it is necessary to protect the coating of ship outer plate. Two methods are generally used on site: 1. removing all dynamic energy pipelines before coating spraying operation of outer plate; the disadvantage is that it affects production progress; 2. erecting scaffolding tooling on side or welding tooling on deck to ensure that dynamic energy pipeline is kept away from outer plate; the disadvantage is that dynamic energy pipeline is still close to ship outer plate after removing regional scaffolding, and welding tooling on deck will damage paint inside reverse cabin.

[0003] Therefore, it is necessary to provide a protective tooling suitable for ship outer plate pipeline operation to solve the above technical problems. CONTENT OF UTILITY MODEL

[0004] The utility model aims at the deficiency existing in prior art, and provides a protective tooling suitable for ship outer plate pipeline operation, which is not only convenient to disassemble and assemble, but also can ensure that dynamic energy pipeline and ship outer plate always keep sufficient distance, thereby ensuring the continuity of production.

[0005] To achieve the above-mentioned purpose, the utility model adopts the technical scheme that:

[0006] A protective tooling suitable for ship outer plate pipeline operation includes a support frame, two vertical support rods are fixed on one side of the support frame close to ship rail, and an inclined support rod is fixed between the support rod and the support frame. Double-layer hooks are arranged on the side of the support rod away from the support frame, a rubber sleeve is arranged on the hooks, extension parts are arranged at both ends of the support frame away from the ship rail, vertical upward limiting columns are arranged on the extension parts, first rollers are arranged on the limiting columns, and second rollers are arranged on the side of the support frame away from the ship rail.

[0007] Preferably, the hooks are n-shaped structures welded on the support rods, and the hooks are engaged with the ship rail.

[0008] Preferably, a connecting rod for support is fixed between the two support rods.

[0009] Preferably, the first rollers and the second rollers are nylon rollers.

[0010] Preferably, the support frame, the vertical rod, the inclined support rod and the limiting column are all made of steel pipes.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. The double-layer hooks are hung on the ship rail, and the power supply pipelines are arranged on the support frame, so that the power supply pipelines and the ship plate are always kept apart, the ship plate is conveniently sprayed, and the sprayed plate coating is not damaged.

[0013] 2. The limiting columns are arranged on the extension parts of the support frame, so that the power supply pipelines arranged on the support frame cannot slide from the two sides; the first roller is arranged on the outer periphery of the limiting column, and the second roller is arranged on the outer periphery of the side of the support frame away from the ship rail, so that the friction coefficient between the power supply pipelines and the support frame and the limiting column is reduced, and the power supply pipelines are prevented from being damaged due to dragging friction.
