[0059] 2. Regarding the preheating and annealing in "Preparation of end-disk integration":

[0060] In the present invention, during the assembly process of the end plate integration 2 and the cylinder body 1, before and after the welding of the side plate 21 and the cylinder shaft 23, they need to be preheated and annealed. The reason is that:

[0061] The side plate 21 and the cylindrical shaft 23 are generally made of medium carbon high-strength steel, and the thickness of the side plate 21 and the cylindrical shaft 23 is relatively thick. In order to ensure the welding quality and prevent cracks on the side plate 21 and the cylindrical shaft 23 during welding, this The invention preheats and anneals the side plate 21 and the cylinder shaft 23 before and after welding, so that not only can effectively avoid the occurrence of cracks, but also can obtain a better welding effect and ensure the firmness of the connection.

Abstract

The invention relates to a roller built in a double-brake flange for a large towing winch. The roller adopts a double-brake flange built-in structure and comprises a roller body, end plate assemblies and brake flange assemblies, wherein the end plate assemblies and the brake flange assemblies are correspondingly arranged; each brake flange assembly is positioned at the inner side of the corresponding end plate assembly and comprises side plates, rib plates and roller shafts; and each brake flange assembly comprises brake flanges and supporting plates. The manufacturing method comprises the following steps in sequence: part preparation, brake flange assembly preparation, end plate assembly preparation, final assembly, and welding and correction. Not only is the whole process clear and easy to operate, but also the manufactured roller is lighter in mass. The roller has the advantages of lighter weight, lower manufacturing difficulty, higher safety and suitability for reduction of use difficulty.

Description

technical field [0001] The invention relates to a roller for a large towing machine, in particular to a roller with a built-in double-brake rim for a large towing machine and a manufacturing method thereof, which is particularly suitable for lowering the roller on the basis of meeting the force requirements of a large towing machine. the quality of. Background technique [0002] The towing crane is an important large-scale equipment used on marine engineering ships. At present, the domestic large-scale towing cranes over 100 tons are basically monopolized by foreign manufacturers, especially the super-large towing cranes of 500 tons. The drum assembly is the key equipment for braking and transmitting power of the towline machine. The drum assembly is mainly composed of a drum, a low-speed gear and a rope pressing block assembly. Among them, the drum is the key stress-bearing part. Due to the large load force, the drum structure The mass is very large, which increases the di...
