A new type of pull-twist combined test device for flexible umbilical cables in marine engineering

Abstract

The invention discloses a novel marine engineering flexible tube cable tension torsion combined test device, which comprises a fixed end support, two fixed supports, a gear and a shaft, wherein the fixed end support, the two fixed supports, the gear and the shaft are sequentially arranged along a straight line; a guide bar is arranged on the shaft, connection disks are arranged at the two ends of the shaft, clamp bars are arranged at the external edges of the connection disks, the shaft is connected with a bearing through the clamp bars and a clamp groove, the shaft is connected with the gear through the guide bar and a through groove, and a connector is arranged on the connection disk on one side, far from the fixed end support, of the shaft. The connector is mechanically assembled in an embedded mode, a connection base can rotate around the axis of a drum-shaped connection portion under the action of a lubrication agent and the gear; on one hand, the connector can prevent a second tension actuator from affecting a torsion effect; on the other hand, the geometric shape of the drum-shaped connection portion can effectively guarantee that the second actuator can apply larger tension load, tension and torsion are prevented from affecting each other, and a structural test of the tube cables under coupling loading is achieved.

Description

technical field [0001] The invention relates to the field of testing flexible umbilical cables in marine engineering, in particular to a novel pull-twist combined testing device for flexible umbilical cables in marine engineering. Background technique [0002] Coal, oil and natural gas are the three major energy sources that drive the world's industrial development. Among them, oil and gas resources are widely distributed, and a large part of them are distributed in various sea areas of the earth. At present, offshore oil and gas are mainly exploited and transported through fixed offshore platforms and various forms of floating bodies, and the development and application of mining equipment connected between the water surface and the seabed has become an important part of this development model. One of the important types of equipment is the marine flexible umbilical, and its structure is usually composed of corresponding functional components and strengthening components s...
