The invention discloses a protective mechanical device for steel rail hoisting. The protective mechanical device comprises an adjusting mechanism, a damping mechanism is welded to the top of the adjusting mechanism, a supporting mechanism is embedded in the center of the top of the damping mechanism, a downward pressing mechanism is movably installed at the top of the damping mechanism, and the adjusting mechanism comprises a fixing base; and open grooves are formed in the two sides of the top of the fixing base, moving grooves are formed in the bottoms of the open grooves, and double-threaded rods are rotationally connected to inner cavities of the moving grooves. According to the scheme, a steel rail firstly falls to the top of an isolation pad, the isolation pad pushes two sliding blocks through a movable rod at the bottom to compress a first damping spring, a certain buffering effect can be achieved before the steel rail falls to a sleeper, the situation that the steel rail makes direct contact with the sleeper is avoided, and the speed when the steel rail makes contact with the sleeper can be reduced, therefore, the purpose of protecting the steel rail and the sleeper is achieved, the hoisting operation of the steel rail is facilitated, and the hoisting efficiency is greatly improved.

    本发明公开了一种用于钢轨吊装的防护机械装置,包括调节机构,所述调节机构的顶部焊接有减震机构,所述减震机构顶部的中心处嵌设有支撑机构,所述减震机构的顶部活动安装有下压机构,所述调节机构包括固定座,所述固定座顶部的两侧均开设有开槽,所述开槽的底部开设有移动槽,所述移动槽的内腔转动连接有双螺纹杆;本方案,钢轨先落位至隔垫的顶部,隔垫通过底部的活动杆推动两个滑块压缩第一减震弹簧,能够在钢轨落位在轨枕之前起到一定的缓冲作用,避免了钢轨直接与轨枕接触的状况,能够延缓钢轨与轨枕接触时的速度,进而起到了保护钢轨和轨枕的目的,方便了钢轨的吊装操作,极大的提高了吊装效率。
