The invention discloses a shipborne electric variable-amplitude crane with lifting and variable-amplitude double-steel-wire-rope linkage safety protection. The shipborne electric variable-amplitude crane comprises an electric variable-amplitude crane body and a double-steel-wire-rope linkage safety protection device. The electric luffing crane is provided with a lifting steel wire rope and a luffing steel wire rope; the double-steel-wire-rope linkage safety protection device comprises a guide rail fixed relative to the suspension arm, a first rope guide barrel through which a lifting steel wire rope penetrates and a second rope guide barrel through which a variable-amplitude steel wire rope penetrates are arranged on the guide rail in a sliding mode, and the first rope guide barrel and the second rope guide barrel are connected through an elastic supporting part and are in a linkage state. A first pressure telescopic rod is arranged between the first rope guide barrel and an end base of the guide rail, and a second pressure telescopic rod is arranged between the second rope guide barrel and an end cover of the guide rail. The hoisting steel wire rope and the variable-amplitude steel wire rope are in traction linkage through the double-steel-wire-rope linkage safety protection device, the state of any steel wire rope can be accurately detected, rope correction and return are conducted under the condition that any steel wire rope deviates from a rail, and the operation safety of the shipborne electric variable-amplitude crane is improved.

    本发明公开了具备起升与变幅双钢丝绳联动安全防护的船载电动变幅吊,包括电动变幅吊和双钢丝绳联动安全防护装置;电动变幅吊具有起升钢丝绳以及变幅钢丝绳;双钢丝绳联动安全防护装置包括相对吊臂固定的导轨,导轨上滑移设置有经起升钢丝绳穿过的第一导绳筒和经变幅钢丝绳穿过的第二导绳筒,第一导绳筒与第二导绳筒之间通过弹性支承部相连处于联动状态;第一导绳筒与导轨的端座之间设置有第一压力伸缩杆,第二导绳筒与导轨的端盖之间设置有第二压力伸缩杆。本发明通过双钢丝绳联动安全防护装置将起升钢丝绳与变幅钢丝绳进行牵引联动,能够精确检测任一钢丝绳的状态,并在任一钢丝绳发生偏轨情况下进行校绳回正,提高船载电动变幅吊的作业安全。
