A through bolt protection cover is composed of a cover shell and an eyebolt. The protective cover shell is formed by welding an annular barrel and a top cover plate, and the eyebolt is welded in a circular hole of the circular top cover plate. The device is used on various large-cylinder-diameter low-speed diesel engines, and is convenient to use, simple, attractive and safe. After the through bolt protection cover is applied, the end head of the through bolt on the low-speed diesel engine is protected from being damaged, and the through bolt protection cover has the biggest advantages that the protection cover is light in piece weight and convenient to carry manually, and a hoisting hole with a thread in the right center of a hoisting bolt nut is formed. And the assembling speed is increased, and the assembling efficiency is improved.

    贯穿螺栓保护罩,有罩壳和吊环螺栓组成。保护罩壳是由环形桶形和顶盖板焊接而成,吊环螺栓焊接在圆形顶盖板的圆形孔内。用在多种大缸径低速柴油机上,使用方便,简单、美观、安全。该贯穿螺栓保护罩应用后,保护了低速柴油机上的贯穿螺栓端头不受损害,最大优点在于该保护罩单重轻,便于人工搬拿,起吊螺栓螺帽上正中心开有螺纹的吊装孔。用于吊车起吊,加快了装配速度,提高了装配效率。
