The invention provides a double-lug hoisting appliance for hoisting a low-speed diesel engine complete machine for ships and a using method. The double-lug hoisting appliance comprises a bottom plate,wherein a hoisting plate is vertically welded to the middle of the top part of the bottom plate; a reinforcing structure is arranged between the two outer side walls of the hoisting plate and the bottom plate; a plurality of through holes are machined symmetrically at the periphery of the bottom plate; support casing pipes are vertically fixed to the positions where the through holes are located;and a first hoisting lug hole and a second hoisting lug hole are symmetrically machined on the hoisting plate. By adopting the double-hoisting-lug hoisting appliance disclosed by the invention, the hoisting capability of the hoisting appliance is improved, and the double-hoisting-lug hoisting appliance is superior to a single-hoisting-lug hoisting appliance, and a hoisting transportation requirement of the diesel engine complete machine can be realized more easily; the trouble that a stand of the diesel engine needs to be dismounted, then is transported at the shipyard and is mounted again after the stand of the diesel engine is tested is avoided; the production period is shortened; and the technical problem caused by dismounting the low-speed diesel engine at the second time is avoided.
本发明提供了一种船用低速柴油机整机起吊用双耳吊具及使用方法,它包括底板,所述底板的顶部中间部位垂直焊接有吊板,所述吊板的两外侧壁与底板之间设置有加强结构;所述底板的外围对称加工有多个通孔,所有的所述通孔所在位置均垂直固定有支撑套管;所述吊板上对称加工有第一吊耳孔和第二吊耳孔。采用本发明的双耳孔吊具,提升了吊具起吊能力,优于单耳孔吊具,更容易实现柴油机整机吊装发运要求,避免柴油机台架试验后需拆卸、而后运抵船厂又需重新安装的麻烦,缩短了生产周期,而且避免了低速柴油机因为二次拆装所带来的技术问题。
