Abstract

The invention discloses a balanced hoisting mechanism for hoisting a heavy piece. The balanced hoisting mechanism comprises two side hoisting tools and a middle hoisting tool, wherein the two side hoisting tools are connected with the heavy piece by side hoisting lug plates; the middle hoisting tool is connected with the heavy piece by a middle hoisting lug plate; each of the side hoisting tools and the middle hoisting tool comprises a hoisting tool distribution beam and a hook; a guide rail is arranged at the upper end of each hoisting tool distribution beam and is connected with a hoisting point sliding block; the upper end of each hoisting point sliding block is connected with the corresponding hook; one side of each hoisting point sliding block is connected with a hoisting tool oil cylinder; the other end of each hoisting tool oil cylinder is fixedly connected with the corresponding hoisting tool distribution beam. The balanced hoisting mechanism can be used for solving the problem that hoisting points are not uniform in stress during the hoisting of the heavy piece, and has the characteristic of being simple in structure, convenient to operate, and high in adaptability.

Description

technical field [0001] The invention relates to a balanced hoisting mechanism for hoisting heavy parts. Background technique [0002] For the hoisting of heavy parts over 300t, the existing hoisting mechanism includes a hoisting device, which is connected to the heavy part through the hoisting lug plate. The lifting point is pulled by a winch. When the pulling speed of the winch is not synchronized, the lifting points will not be in the same plane. Some lifting points will be lost, and the tension on the remaining lifting points will increase. If some lifting points are under too much force, there will be a risk that the tension on the lifting points will be greater than the maximum bearing capacity of the hoist. Contents of the invention [0003] The object of the present invention is to provide a balanced hoisting mechanism for hoisting heavy objects, which solves the problem of uneven stress on each lifting point when hoisting heavy objects, and has the characteris...
