Submarine cable bending tester

Abstract

A submarine cable bending tester comprises a driven wheel assembly, a driving wheel assembly and a driving assembly, wherein the driven wheel assembly comprises at least two driven wheels with different diameters and a main shaft vertically mounted on the ground; the driven wheels can be coaxially stacked on the main shaft in an autorotation manner and are horizontally arranged; the driving wheel assembly comprises a driving wheel guide rail and a driving wheel stand mounted on the ground, a motor mounted on the driving wheel stand, and a driving wheel mounted at the motor output end; the driving wheel is horizontally arranged; the driving wheel stand is mounted on the driving wheel guide rail in a sliding manner through a liftable driving wheel caster base; the driving assembly comprises a bearing portal, a lifting oil cylinder mounted at the top of the bearing portal in an inserting manner, a master cylinder transversely arranged and a counterforce bar; the master cylinder is mounted in the bearing portal in a vertical sliding manner; the cylinder body of the master cylinder is connected with the telescopic end of the lifting oil cylinder; the telescopic end of the master cylinder is connected with one end of the counterforce bar through a cross beam; the other end of the counterforce bar is connected with the driving wheel stand. The submarine cable bending tester is applicable to submarine cable testing.

Description

technical field [0001] The invention relates to a submarine cable test device, in particular to a submarine cable bending test device. Background technique [0002] At present, with the vigorous development of the global power and communication industries, the demand for submarine cables has increased dramatically, and the importance of submarine cable inspection has become increasingly prominent. Generally, the various indicators of the submarine cable are tested by a submarine cable test device, wherein the traditional structure of the submarine cable bending test device generally includes a single driven wheel and two hoists. During the concrete work of this submarine cable bending test device, at first, connect the two ends of sample (submarine cable) respectively with one end of two steel wire ropes; The sample is set on the driven wheel; finally, the test can be bent on the driven wheel by coordinating the reciprocating pull of the sample by two hoists (the bent sampl...

Problems solved by technology

[0003] Since the submarine cable bending test device has only one driven wheel, when samples with different diameters need to be tested, the original driven wheel must be removed and replaced with a suitable diameter driven wheel to continue the test. In this way, the test operation is very troublesome and efficient. Low
