According to the technical scheme, a horizontal section of a T-shaped groove of a thick-wall steel pipe is connected with the top end of an outer plate in an inserted mode, a vertical section of the T-shaped groove is connected with a lug plate in an inserted mode, the thick-wall steel pipe is fixed to the top of the outer plate by means of a bolt through a steel pipe through hole and an outer plate through hole, a steel wire rope penetrates through a shackle, and the shackle is fixed to the top of the outer plate. The shackle pin of the shackle penetrates through the lug plate and is screwed and fastened with the shackle head, the steel wire rope is hoisted and stressed in sections, the shackle is pressed to the thick-wall steel pipe under the pulling force of the steel wire rope until hoisting is completed, and when the steel wire rope is not stressed, the shackle pin is detached, the steel wire rope is detached, the bolt for fixing the thick-wall steel pipe and the outer plate is loosened, and the thick-wall steel pipe is detached from the top of the outer plate. By using the method, the damage to the outer plate caused by segmented hoisting is avoided, the extra workload of workers is reduced, and the labor cost is reduced.
本发明公开了一种船舶分段吊装外板保护装置及其使用方法,其技术方案是:将厚壁钢管T型槽的水平段与外板顶端插接,T型槽的竖直段与耳板插接,利用螺栓通过钢管通孔和外板通孔将厚壁钢管固定在外板顶部,将钢丝绳穿过卸扣,卸扣的卸扣销穿过耳板,与卸扣头螺接紧固,钢丝绳分段吊装受力,卸扣收到钢丝绳的拉力压向厚壁钢管,直到吊装完成,等钢丝绳不受力时拆下卸扣销,卸掉钢丝绳,松开用于固定厚壁钢管与外板的螺栓,将厚壁钢管从外板顶部拆卸。使用本方法避免了分段吊装对外板造成的损伤,减少了工人额外的工作量,降低了用工成本。
