Embodiment

[0027] The lifting of the super large circular part of the present invention will be described in detail below in conjunction with the process of lifting a circular part with a weight greater than 15 tons and a diameter of more than 5 meters from the horizontal to the vertical and then transported to the installation position in conjunction with a diesel engine. method.

[0028] Utilize the hoisting method of super large annular part of the present invention to lift the super large annular part of marine diesel engine, mainly comprise following concrete steps:

[0029] ① Fix four auxiliary lifting tools 1 on the circumference of the outer circle edge of the super large circular part placed horizontally. Bolt 13 is tightened, as shown in Figure 3;

[0030] ②Use a hoisting device with main hook 2 and auxiliary hook 3 to move to the super large ring-shaped part placed horizontally, and first wrap the wire rope on the main hook 2 around the outer circumference of the super large ...

Abstract

The invention relates to a hoisting method of an ultra-large cirque part. The method comprises the following steps that (1) a plurality of auxiliary hoisting tools are fixed at the circumference of the external circumferential edges of an ultra-large cirque part horizontally arranged; (2) a hoisting device with main hooks and auxiliary hooks are moved to the ultra-large cirque part, the cable wires on the main hook round the external circumference of the art and are clamped on the auxiliary hoisting tool, and the cable wire on the auxiliary hook passes through the internal round of the part; (3) the auxiliary hook is lifted with the ultra-large cirque part being gradually pulled from horizontal state to vertical state; (4) the main hook is lifted to lead the cable wire on the main hook to be tightened, thus leading the main hook to bear the weight of all the whole ultra-large cirque part; (5) the auxiliary hook is loosened, and the ultra-large cirque part is hoisted and pulled to the installation position by the main hook. By the arrangement of the structure and the method, large or even ultra-large cirque parts can be easily hoisted without affecting that the parts takes internal holes as the installation positions and damaging the part; furthermore, the invention has the advantages of stable and safe hoisting and high efficiency.

Description

technical field [0001] The invention relates to a mechanical handling method, in particular to a lifting method and an auxiliary lifting tool for super large circular parts, which can make super large circular parts without lifting points on the circumference turn from a horizontal state to a vertical lifting installation. Background technique [0002] In many mechanical fields, equipment parts are large and heavy. For example, many large circular parts are used in large ships and hydropower stations. [0003] Take several super-large annular parts of marine low-speed diesel engines as an example. After these parts are manufactured, their packaging, transportation and even unpacking are placed in a horizontal manner, while the installation state of this part is vertical installation. Most of them are like this Hanging holes cannot be arranged on the circumference of the part. Therefore, it needs to be converted into a vertical state before installation before installation. ...
