Movable ocean engineering flexible pipe cable torsion test device

Abstract

The invention discloses a movable ocean engineering flexible pipe cable torsion test device. The movable ocean engineering flexible pipe cable torsion test device comprises a fixing end support, two fixing supports and a multi-stage gear, wherein the fixing end support, the two fixing supports and the multi-stage gear are sequentially and linearly arranged. The multi-stage gear is connected with a supporting table through a rack I. The supporting table is provided with an actuator and is further provided with a rack support I and a rack support II. The rack support I comprises a rack fixing plate I. The rack support II comprises a rack fixing plate II. Guide rails II parallel with guide rails I are arranged between the rack fixing plate I and the rack fixing plate II and are provided with a rack II pressing the multi-stage gear on the rack I. The lower ends of the fixing supports are provided with guide rails III perpendicular to the guide rails I. According to the movable ocean engineering flexible pipe cable torsion test device, the actuator drives the racks to complete rotation of the gear, operation is more convenient, labor is saved, operation is precise, torque loading is more flexible, and the movable ocean engineering flexible pipe cable torsion test device can be used for torsion testing of various pipe cables.

Description

technical field [0001] The invention relates to a test device, in particular to a movable torsion test device for flexible umbilical cables in marine engineering. Background technique [0002] Flexible umbilical cables for offshore engineering are widely used in offshore oil and gas production. Typical umbilical cables include: 1. The submarine cable that provides power and electricity for the submarine development device; 2. The umbilical cable that is connected between the water platform and the submarine manifold to play a control function; 3. Used to transport the extracted oil and gas to Flexible piping for storage equipment. These flexible umbilical cables are an important part of key equipment for the development of offshore oil and gas resources, and are the "lifeline" to ensure the normal operation of oil and gas fields. Due to the influence of factors such as working load, floating body movement and complex marine environment, it is easy to cause failure of vario...

Problems solved by technology

There are many disadvantages in this torque loading method: 1. For the umbilical structure with small torsional rigidity, it is relatively convenient to use the chain hoist 1`; A larger bending moment can only be achieved with a longer transmission arm, which is obviously not conducive to the implementation of limited space in the laboratory

2. At the same time, as the rotation angle increases during the loading process, the direction of the force exerted by the chain hoist 1` will continue to change along the direction of the rope, so the uneven variation of its torque will affect the stability of the test results

3. Relying on the loading method of chain block 1`, manual force can only be applied intermittently, so the loading speed cannot be well controlled

At the same time, due to the structural characteristics of the chain block 1`, a certain rebound will occur after each force is applied, which brings great inconvenience to the later data processing
