Hoisting mechanism for high-speed railway construction

The utility model discloses a hoisting mechanism for high-speed railway construction, which relates to the technical field of construction instruments, solves the problem of low efficiency of small-spacing hoisting, and comprises a support rod, a support mechanism for adjusting the hoisting range is connected above the support rod, a connecting mechanism for connecting a binding rope is arranged on one side of the support mechanism, and the binding rope is arranged on the other side of the support mechanism. A counterweight mechanism used for counterweight balance is arranged on one side of the lower portion of the supporting rod. The hydraulic cylinder pushes the supporting arm to stretch out and draw back, so that the hoisting range is adjusted, meanwhile, the hydraulic rod stretches out and draws back, under rotation and supporting of the first connecting block and the second connecting block, supporting is carried out between the supporting arm and the supporting rod, the bearing capacity is improved, mea
