Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] The invention provides a crane installation process, which comprises the following steps:

[0023] Step 1. Measure the size of the joint between the crane base and the mast

[0024] 1) When the gram suspension base arrives at the factory, it is first necessary to measure the flatness of the flange surface of each gram suspension base, and form a measurement report in time as a reference for welding construction before welding;

[0025] 2) Meas...

Abstract

The invention relates to a crane installation process. The crane installation process includes: step 1, obtaining planeness of a flange plane of a crane base seat, obtaining the length, the width andthe diagonal size of the crane base seat and crane mast body connection ports, and detecting deviation value between the crane base seat and each crane mast body connection port; step 2, hoisting a mast body, fixing the mast body on a ship body through welding, surveying and scribing a 100 horizontal reference line on a folding opening of an upper port and completing drift pin marking after construction completes, hoisting the crane base seat, and surveying and scribing the other 100 horizontal reference line on a folding opening of a lower port and completing drift pin marking; step 3, aftercompleting inspection of the size of the crane base seat and confirming that accuracy of the size of the crane base seat meets requirements, butting the crane base seat against the mast body, and placing and welding the crane base seat and the mast body in the vertical direction. The crane installation process is simple, can directly hoist the components onto the ship body for installation, reduces construction difficulty, and improves construction efficiency, and by adopting the above welding method for welding, quality of a welding seam can be guaranteed, and hoisting safety is ensured.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a crane installation process. Background technique [0002] The Crane Crane is a new type of deck crane suitable for the operation needs of offshore engineering ships.
