A guide belt reversing device and a guide belt reversing method thereof

Abstract

The invention discloses a conduction-band reversing device. The conduction-band reversing device comprises a first row of steering wheels and a second row of steering wheels which are arranged at interval up and down. The second row of steering wheels comprise multiple steering wheels with circumferential grooves. The widths of the circumferential grooves in the steering grooves of the second row of steering wheels shrinks from front to back in sequence, wherein the width of the circumferential groove in the first steering wheel of the second row of steering wheels is no smaller than that of a deformed steel bar, and the thickness of the circumferential groove in the last steering wheel of the second row of steering wheels is no smaller than that of a deformed steel bar. The first row of steering wheels and the second row of steering rows are both vertically arranged instead of being horizontally arranged from front to back. The reversing work of the deformed steel bar can be achieved. The invention further discloses a use method of conduction-band reversing device.

Description

technical field [0001] The invention relates to the technical field of guide belt reversing, in particular to a guide belt reversing device and a guide belt reversing method thereof. Background technique [0002] At present, the application of oil pipeline hoses is becoming more and more widespread, especially onshore oil exploitation is becoming increasingly scarce, and the proportion of subsea oil exploitation will increase, which will inevitably increase the demand for marine hoses. [0003] Due to the particularity of the use environment, the marine hose needs to have high pressure resistance. Now the marine hose is generally armored, and a pressure-bearing layer is added to the outside of the marine hose. [0004] When making the pressure-bearing layer, special-shaped steel bars need to be introduced into the armoring machine. The special-shaped steel bars include S-shaped steel bars and Z-shaped steel bars. The special-shaped steel bars themselves are placed in rolls. ...

Problems solved by technology

[0004] When making the pressure-bearing layer, special-shaped steel bars need to be introduced into the armoring machine. The special-shaped steel bars include S-shaped steel bars and Z-shaped steel bars. The special-shaped steel bars themselves are placed in rolls. The special-shaped steel strips are continuously wound on the marine hose. In this process, the special-shaped steel strips need to change their state, and the special-shaped steel strips need to be reversed, from the state of being parallel to the horizontal plane and advancing along the horizontal plane to being erected vertically relative to the horizontal plane. And in the state of advancing along the vertical plane, this conversion is very complicated, and it is very easy to cause loss to the special-shaped steel bar itself
