Embodiment Construction

[0020] Below we further elaborate the present invention in combination with the accompanying drawings and specific embodiments in order to understand the working principle of the present invention more clearly, but the protection scope of the present invention cannot be limited by this.

[0021] like figure 1 As shown, the present invention is a method for installing large shafts in ships and marine engineering, the purpose of which is to transport large and heavy shafts such as stern shafts to the installation location smoothly and expressly, so as to realize fast and safe installation. The auxiliary device structurally includes a V-shaped bracket 2, an adjustment frame 4, a hydraulic cylinder 8, a driving traveling mechanism 18, a roller 10 and a heavy rail 17. A V-shaped groove is arranged on the upper part of the V-shaped bracket 2, and the large-scale shafts including the stern shaft 1 are placed in the V-shaped groove. As an optimized design, the upper part of the V-shap...

Abstract

The invention relates to a method for mounting large shafts in a ship and ocean engineering. The method comprises the following steps of 1, manufacturing an auxiliary device used when the large shafts are mounted; 2, transporting isometric pull rods, thick-walled seamless tubes and heavy rails in the auxiliary device to an engine room area of a built-in ship or ocean engineering; 3, assembling a V-shaped supporting frame, an adjusting frame, a hydraulic oil cylinder, a driving travelling mechanism and rolling wheels in the auxiliary device into a whole trolley, and lifting the whole trolley to the place above the heavy rail, so that the rolling wheels of the whole trolley are clamped on the heavy rail; 4, placing the large shafts, including a propeller shaft, into the V-shaped supporting frame of the whole trolley, so that the V-shaped supporting frame is uniformly stressed; 5, driving the rolling wheels through the driving travelling mechanism of the whole trolley, so that the shafts safely and smoothly enter mounting positions and are mounted. According to the method provided by the invention, mounting of the large shafts can be relatively quickly and better added, the working efficiency can be obviously improved, and the work load is reduced.

Description

technical field [0001] The invention relates to the field of ship and marine engineering construction, in particular to an auxiliary device used in the installation of large or heavy shafts during construction. Background technique [0002] The large shafts involved in ships and ocean engineering are mainly shafts related to the power plant system. These shafts, especially the shafts of the main propulsion device, provide the driving force for the entire ship and ocean engineering. The volume and weight of these shafts are compared When installing, you need to pay attention to the safety and accuracy of hoisting. For example, since these stern shafts have very small mounting clearances to the stern bushing, etc., precise mounting is of great importance. [0003] In the installation process of large-scale shafts in the prior art, due to the relatively large volume and weight of these shafts, some of them are tens of meters long and weigh close to 100 tons. If the traditiona...
