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

Abstract

A submarine cable bending test device, comprising a driven wheel assembly, a driving wheel assembly and a driving assembly; the driven wheel assembly includes at least 2 driven wheels of different diameters and a main shaft vertically installed on the ground, and the driven wheels can rotate coaxially Installed on the main shaft, the driven wheels are arranged horizontally; the driving wheel assembly includes the driving wheel guide rail installed on the ground, the driving wheel frame, the motor installed on the driving wheel frame and the driving wheel installed at the output end of the motor, and the driving wheel is arranged horizontally. The driving wheel frame is slidably installed on the driving wheel guide rail through the movable driving wheel caster seat; the driving assembly includes the load-bearing mast, the lifting oil cylinder inserted on the top of the load-bearing mast, the main oil cylinder and the reaction bar arranged horizontally, the main oil cylinder can be It is installed in the load-bearing mast slidingly up and down, and the cylinder part of the main oil cylinder is connected with the telescopic end of the lifting oil cylinder. The telescopic end of the main oil cylinder is connected with one end of the reaction force bar through a beam, and the other end of the reaction force bar is connected with the driving wheel frame. connected. Applicable to the inspection of submarine cables.

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...
