Embodiment 1

[0043] Embodiment 1: Adopt the above-mentioned mechanism, wherein 16 wire rope guide brackets are set on the mobile car, the winding hose does not move, and the mobile car walks. There are two rows of bobbin assemblies with friction devices on each wire rope guide bracket. Each column includes 5 spool assemblies with friction devices, and 1 variable frequency motor provides untwisting power for 10 spool assemblies with friction devices. The rotation angles or rotation speeds of the 10 bobbin assemblies with friction devices are consistent when they work. When the angle between the wire rope and the winding hose is 30°, according to the formula X=cosα, the twist is calculated to be 0.866, that is, the twist of the steel wire or steel wire rope is 0.866 turns for each rotation of the hose mandrel. Eliminate this twist, and the spool assembly with friction device on the wire rope guide bracket will actively untwist 0.866 turns. There are 16 wire rope unwinding brackets on the mo...

Embodiment 2

[0044] Embodiment 2: adopt the above-mentioned mechanism, 20 wire rope guide brackets are arranged on the fixed frame mechanism, and each wire rope guide bracket has a shaft head that can rotate on it up and down the bracket frame. During work, the wire rope The unwinding mechanism does not move, and the winding hose moves. There are 200 bobbin assemblies with friction devices on the 20 wire rope unwinding brackets, and 20 variable frequency motors provide untwisting power for the 200 bobbin assemblies with friction devices. The angle between the wire rope and the winding hose is 75°. According to the formula X=cosα, the twist is calculated to be 0.2588, that is, the twist of the steel wire or steel wire rope is 0.2588 turns for each rotation of the hose mandrel. To completely eliminate this Twist, the spool assembly with friction device on the wire rope guide bracket should actively pay off 0.2588 turns. The data is sent to the frequency converter by the PLC, and the frequenc...

Embodiment 3

[0046] Embodiment 3: adopt the above-mentioned mechanism, 23 wire rope guide brackets are arranged on the fixed mechanism, each wire rope guide bracket has a shaft head that can rotate on it above and below the bracket frame, during work, the wire rope guide The opening mechanism does not move, and the coiled hose moves, and there are 10 spool assemblies with friction devices on each wire rope guide bracket, and 1 frequency conversion motor provides twisting power for 10 spool assemblies with friction devices. The angle between the wire rope and the winding hose is 54°44'. According to the formula X=cosα, the twist is calculated to be 0.5774, that is, the twist of the steel wire or steel wire rope is 0.5774 turns for each rotation of the hose mandrel. Eliminate this twist, and the spool assembly with friction device on the wire rope guide bracket will actively pay off the wire for 0.5774 turns. The PLC sends the data to the frequency converter, and the frequency converter cont...

Abstract

The invention provides a cotton rope unwinding device and a method for unwinding a cotton rope. The cotton rope unwinding device and the method for unwinding the cotton rope are used for unwinding of twist generated by the cotton rope when the cotton rope is wound on a hose tube. The cotton rope unwinding device comprises a power transmission mechanism and a cotton rope unwinding mechanism, wherein the cotton rope unwinding mechanism comprises a plurality of rotatable cotton rope unwinding supports, a plurality of bobbin assemblies with friction devices are installed on each cotton rope unwinding support, the bobbin assemblies with the friction devices rotate to unwind the rope under the effect of the power transmission mechanism, and the twist generated during winding is eliminated. According to the cotton rope unwinding device and the method for unwinding the cotton rope, the problem of twist influences generated in an existing winding process is solved, the twist is eliminated in an active mode, original influences of the twist generated during the winding on a hose tube production procedure are eliminated, influences of the twist on winding uneven laying are eliminated, and a use ratio of original characteristics of materials is improved.

Description

technical field [0001] The invention belongs to the technical field of rubber products, and relates to a decoupling device and a decoupling method for winding steel wires, steel cords, steel wire ropes, etc. on a hose mandrel. Background technique [0002] In land drilling, offshore drilling and oil transportation, some large-diameter and high-pressure delivery hoses are required. The production of these hoses needs to be wound and laid with high-strength steel wires or wire ropes as the skeleton layer of the hose. These skeletons The layer winding process and equipment determine the surface state of the winding skeleton layer, and the surface state of the skeleton layer plays a vital role in the pressure bearing capacity of the hose. [0003] During the spiral winding process of the steel wire or steel wire rope on the hose mandrel, when the steel wire or steel wire rope is wound on the hose mandrel, the helical twist will also be generated on the steel wire or steel wire r...
