Embodiment Construction

[0013] The present invention will be described in detail below with reference to the drawings and embodiments.

[0014] Such as figure 1 , figure 2 As shown, the device of the present invention includes a test bench 2 set on the foundation 1, and a U-shaped configuration line (such as figure 2 Shown by the dotted line). The curved section 3 of the U-shaped configuration line is a semicircular arc line. A loading device 4 is set at the outlet end of the U-shaped configuration line to apply a corresponding load to the umbilical cable sample 5; a tensile device 6 is set at the return end of the U-shaped configuration line to apply a corresponding load to the umbilical cable sample 5 Stretch. On the straight line between the loading device 4 and the starting point of the bending section 3, a number of anchor piles 7 fixedly connected to the test bench 2 are arranged at intervals, and the last anchor pile 71 is located at the starting point of the bending section 3; A number of ...

Abstract

The invention relates to a test device for the minimum bending radius of an umbilical cable and a usage method of the test device. The test device comprises a test bed, a fixed device and a tension device are arranged on one side of the test bed in a spaced manner, a plurality of anchor piles are arranged on an extension line of the fixed device in a horizontal spaced manner, and accordingly, a plurality of tracks are arranged on an extension line of the tension device in a spaced manner; and a plurality of tracks distributed in a radial form are arranged between the anchor pile which is farthest from the fixed device and the tension device and the tracks, and a mobile pile is arranged in each of the tracks. The test device for the minimum bending radius of the umbilical cable and the usage method of the test device have the advantages of simple structure, easiness in operation and capability of simply and rapidly changing the bending radius of the umbilical cable, and can be widely applied to umbilical cable-related enterprises, research institutes and oil and gas companies.

Description

Technical field [0001] The invention relates to a test device and a use method thereof, in particular to a test device with a minimum bending radius of an umbilical cable and a use method thereof. Background technique [0002] With the continuous increase in the development water depth of offshore oil and gas fields, underwater production technology has received extensive attention from major oil companies around the world with its significant technical advantages and considerable economic benefits. The umbilical cable is one of the key equipment of the underwater production system. The umbilical cable of the underwater production system is a combination of cables (power cables or signal cables), optical cables (single-mode or multi-mode optical cables), hydraulic or chemical pipes (steel pipes or hoses). The main function is to connect the upper module and the underwater The production system, on the one hand, provides electricity, gas, hydraulic power and chemical injection ch...
