Embodiment Construction

[0043] The present invention will be described in detail below in conjunction with the drawings.

[0044] Such as figure 1 As shown, the method for installing the large-tonnage pin on the boom of the offshore ship-borne boom crane of the present invention uses a combined installation tool for installation, and is characterized in that the combined installation tool includes a boom support 11, a support Slide assembly, drafting mechanism, hammer 5, installation crane, guide sleeve 17 and anti-collision guard 15; among them:

[0045] The above-mentioned large-tonnage pin 7 is a stepped shaft with thin ends and thick middle, and a number of tooling screw holes are evenly distributed on the end faces of both shafts;

[0046] The above-mentioned supporting slide assembly includes a supporting tire frame 1, a hydraulic jack 2 and a supporting slide 3;

[0047] The above-mentioned support tire frame is a frame structure, which is placed on the deck of the ship; the number of the above-mentio...

Abstract

The invention discloses a mounting method of a large-tonnage pin on the jib of an offshore shipborne jib type crane. The mounting method has the advantages that a guide sleeve and an anti-collision plate are assembled to a to-be-mounted large-tonnage pin, the large-tonnage pin is mounted through a combined mounting tool, the mounting difficulty of the large-tonnage pin is lowered effectively, mounting efficiency is increased, mounting period is shortened, labor intensity is lowered, and personal safety during mounting is guaranteed; compared with a traditional mounting method, the mounting method is high in mounting efficiency, simple to operate, time saving and labor saving, good in mounting safety, stable and reliable in pin mounting quality, and the like.

Description

Technical field [0001] The invention relates to a method for installing a large-tonnage shaft, in particular to a method for installing a large-tonnage pin shaft on an offshore ship-borne jib crane boom. Background technique [0002] The offshore ship-borne jib crane is huge and heavy, and the large tonnage pin on the jib is large in size and heavy (the length is greater than 2.5m, the diameter is about 1m, and the weight is greater than 10t), which has always been a difficult problem in installation. The installation process is time-consuming and laborious, and during the installation operation, accidents are prone to personal injury. [0003] Especially, due to its special working conditions, the sea water ebbs and flows, the hull is undulating, and swaying from side to side. If the hull is relatively stable during a tidal process (usually, a stable plateau is only about 2 hours) , It is impossible to assemble the large tonnage pin into the pin hole of the boom at one time, it i...
