Assembly method of displacement adaptation mechanism of ship lift

Abstract

The invention discloses an assembly method for a displacement adaptation mechanism of a ship lift. Assembly is sequentially conducted according to the steps. Firstly, a first part is horizontally mounted on a supporting block arranged on an assembly platform; then a second part and a third part are assembled to be a first component and fixed through a rotating-prevention tool; then a fourth part and a fifth part are assembled to be a second component and fixed through a rotating-prevention tool; then a sixth part and a seventh part are assembled to be a third component, and the first componentand the second component are assembled onto the first part to form a fourth component; then the fourth component is lifted by a crane to be assembled onto the third component; the first part is rotated through a lifting hook, so that the first part turns into the vertical state; and finally the first part is supported by a second jack, and then a deformation-prevention tool is mounted. Accordingto the assembly method, the assembly order of all part products of the displacement adaptation mechanism can be optimized, the product assembly height is decreased, the assembly cost is reduced, and the safety hidden trouble is reduced.

Description

technical field [0001] The invention relates to the field of mechanical assembly. More specifically, the present invention relates to an assembly method of a displacement adaptation mechanism of a ship lift. Background technique [0002] A ship lift is a mechanical device that lifts a ship during navigation. During the operation of the ship-bearing box, the position will be shifted due to wind load and unbalanced load. The displacement adaptation mechanism of the ship lift is to adapt to this shift and keep the pinion gear always in contact with the rack during the lifting process of the ship. A mechanism with good meshing and stable lifting. [0003] The structure of the displacement adaptation mechanism of the ship lift is similar to the four-bar linkage mechanism. The four-bar linkage assembly is a quadrilateral structure composed of two vertical bars and two horizontal bars. Under normal working conditions, the quadrilateral is rectangular; When the cabin horizontally...
