Abstract

The invention discloses a tertiary elastic element serially connected variable-rigidity elastic hanging device, which mainly consists of a belt pulley supporting assembly, an upper guide column, a guide sleeve, an upper supporting plate, a belt pulley fixing plate, a flange, a lower guide column, a hanging hydraulic cylinder, a lower supporting plate and a belt pulley pressing assembly. An arrangement structure including an upper layer, a middle layer and a lower layer is adopted, the belt pulley supporting assembly is mounted on the upper layer, the hanging hydraulic cylinder and a belt pulley supporting hydraulic cylinder are mounted on the middle layer, and the belt pulley pressing assembly is mounted on the lower layer; main supporting components include the upper supporting plate and the lower supporting plate which are connected via the guide sleeve in a welded manner, and the lower guide column and the guide sleeve are fixedly mounted on two sides of the upper supporting plate to form a guiding mechanism; and the hanging device is divided into 22 groups of independent variable-rigidity elastic units. The hanging device has the advantages of good passing ability of pipelines and high adaptability to sudden change of tube diameters, and is applied to a crawler-type transmission walking system.

Description

technical field [0001] The invention relates to a suspension device, in particular to a three-stage elastic element serial connection variable stiffness elastic suspension device. Background technique [0002] With the continuous development of offshore oil and gas resources, pipelaying equipment has also received extensive attention. Offshore pipe-laying ship tensioner is an important equipment on the pipe-laying ship. In view of the fact that the research and development of tensioners in my country is still in its infancy, domestic tensioners mainly rely on imports. Therefore, accelerating the localization process of marine pipe-laying marine tensioners is the key to improving my country's deep-sea oil and gas production capacity. [0003] The suspension device is the internal core component of the tensioner, and is the force transmission and support device between the tensioner and the working pipeline. Based on the current situation of the tensioner, the suspension de...
