Description
Technical Field
The invention belongs to the field of manufacturing and processing of marine resource development equipment, and relates to a constant tension control key device in processing of a tensile armor layer of a flexible pipe.
Background
The flexible pipe is an important device for ocean resource development, has higher requirements on the mechanical property, particularly the tensile property, of the flexible pipeline along with the development of ocean resources gradually facing deep sea, and the general structure of the flexible pipe sequentially comprises the following components from inside to outside: the inner skeleton layer, inner sheath, armor layer, abrasionproof layer, oversheath. In the flexible pipe structure, the tensile resistance is mainly provided by a tensile armored steel wire or a steel belt (namely an armor layer) in a spiral winding mode.
The flexible pipe is widely used for a suspended span pipeline, a riser of a deep sea platform and exploitation of marginal oil fields, and is an important component part for ocean resource development. The flexible pipe is a marine product with high technical content and high added value, and the manufacturing process is complex. Most of the flexible pipes in China still depend on high-price import from foreign manufacturers, the ordering period is long, and the service response is not ideal, so the manufacturing and processing technology of the flexible pipes is the 'neck clamping' problem in the aspect of ocean resource development in China. At present, domestic flexible pipes are still in a starting stage, the accumulation of an armor layer winding forming process, armor processing equipment and corresponding technologies is relatively small, and although the domestic flexible pipes exist, the domestic flexible pipes have a great gap with the foreign flexible pipes. The armor plays the protection supporting role in the flexible pipe, prevents that the flexible pipe from producing great axial strain and the effect of pipeline fracture from appearing.
The core equipment for keeping the tension stable in the armoring processing is a constant tension control device, and the uniform distribution of the stress of an armoring layer of the flexible pipe can be ensured only by stably and accurately controlling the tension of a steel belt/steel wire, so that the flexible pipe with good tensile resistance and long service life is produced. However, when the flexible pipe armor layer is wound, the flexible pipe armor layer is influenced by multiple factors, and a constant tension control device in the process of winding the armor layer is a complex control device with multivariable, time-varying and strong coupling. In the process of winding and processing the armor layer, the tension jitter problem is caused by factors such as a plurality of parameters, external interference, time-varying property of winding radius, strong coupling relation of speed and the like, and the control performance of the winding tension control device is influenced by the tension jitter problem, so that the processing quality of products is influenced. Under the trend of development of high requirements on high precision, high stability and the like of tension control in an armor layer winding tension control device at home and abroad, research on the armor layer winding tension control device by a plurality of expert scholars at home and abroad mainly relates to three aspects of the structure, the existing problems and a tension control algorithm of the tension control device. The research in this aspect in China is laggard abroad, the problems of low tension control precision, unsatisfactory armor effect, low performance of the flexible pipe, short service life and the like generally exist, and the development of ocean resources facing deep sea in China is severely restricted.
Disclosure of Invention
The invention aims to provide a key constant tension control device in flexible pipe tensile armor layer processing, aiming at the blank of the related technical field of constant tension control in the domestic flexible pipe tensile armor layer processing.
When the pay-off angle (the included angle (acute angle or right angle) formed by the axial direction of the pay-off drum and the paid-off steel wire or steel belt when the pay-off drum pays off the wire) is changed when the pay-off drum pays off the wire in the cage, the tension of the steel belt/steel wire is changed along with the change of the pay-off angle, and then the mechanism of the influence of the pay-off angle on the tension of the steel belt/steel wire when the pay-off drum pays off the wire in the cage is deeply researched, so that a constant tension control key device in the processing of the tensile armor layer of the flexible pipe is provided.
In order to achieve the purpose, the invention adopts the technical scheme that:
a constant tension control key device in the processing of a tensile armor layer of a flexible pipe comprises a driving part 1, a sliding connection part 2 and a paying-off part.
The paying-off part comprises a paying-off drum 3, a through hole for penetrating through a shaft 23 is formed in the axial direction of the paying-off drum, and the paying-off drum 3 is fixedly assembled on the shaft 23 and used for storing and paying off steel strips/steel wires required in the winding process.
The driving part 1 provides axial rotation and axial movement for the whole tension control key device, and comprises a motor and speed reducer A11, a motor and speed reducer B12 and a hydraulic/worm driving device 13. The motor and speed reducer A11 and the motor and speed reducer B12 are positioned at two sides of the pay-off drum 3, are arranged at two ends of the shaft 23, and are used for driving the pay-off drum 3 to rotate around the axial direction; the hydraulic/worm driving device 13 is fixedly installed in the stranding cage, and a driving rod of the hydraulic/worm driving device 13 is connected with the motor and the right end of the speed reducer B12 and is used for driving the pay-off drum 3 to move along the axial direction.
The sliding connection part 2 comprises a slide block 21, a connecting rod 22 and a shaft 23. The slide block 21 is connected with the shell of the motor and speed reducer A11 and the shell of the motor and speed reducer B12 through a connecting rod 22. The shaft 23 is fixedly connected with the pay-off drum 3 and moves simultaneously. The motor and speed reducer A11 and the motor and speed reducer B12 are mounted on the stranding cage guide rail through the slide block 21 and the connecting rod 22, and the slide block 21 can enable the whole tension control device (except the hydraulic pressure/worm drive device 13) to slide on the stranding cage guide rail.
The basic control mode of the constant tension control key device in the flexible pipe tensile armor layer processing is as follows:
(1) and (5) controlling the pay-off speed.
The speed difference between the paying-off speed and the taking-up speed is one of the main reasons for generating tension of the steel belt/steel wire and is also an important factor influencing the tension of the steel belt/steel wire. When the take-up speed is stable and unchanged and the pay-off speed is larger, the steel belt/steel wire is loosened, and the tension of the steel belt/steel wire is reduced. When the take-up speed is stable and unchanged and the pay-off speed is small, the steel belt/steel wire is tightened at the moment, and the tension of the steel belt/steel wire is increased. Therefore, the tension of the steel belt/steel wire can be controlled by controlling the paying-off speed.
The linear speed (i.e. the paying-off speed) of the paying-off drum 3 is controlled by a motor and a speed reducer A11 and a motor and a speed reducer B12 at two ends of the shaft 23: when the tension of the steel belt/steel wire wound on the pay-off drum 3 is detected to be lower than the set range, the motor and the speed reducer A11 at the two ends of the shaft 23 and the motor and the speed reducer B12 are controlled to perform speed reduction adjustment; when the tension of the steel belt/steel wire is detected to be higher than the set range, the motor and the speed reducer A11 and the motor and the speed reducer B12 at the two ends of the shaft 23 are controlled to perform acceleration regulation, so that the tension of the steel belt/steel wire is controlled within the set range.
(2) And controlling the pay-off position.
When the paying-off drum 3 is paying off, the axial direction of the drum forms an included angle (acute angle or right angle) with a steel wire or steel belt which is paid off: when the tension of the steel wire or the steel belt is detected to be lower than the set range, the driving rod of the hydraulic/worm driving device 13 pushes the motor and the speed reducer B12 to enable the whole device to axially move on the guide rail of the stranding cage along the position deviating from the initial center of the pay-off drum 3 (namely, the direction in which the included angle is reduced), and when the tension of the steel wire or the steel belt is detected to be higher than the set range, the driving rod of the hydraulic/worm driving device 13 pushes the motor and the speed reducer B12 to enable the whole device to axially move on the guide rail of the stranding cage along the position of the pay-off drum 3 close to the initial center (namely, the direction in which the included angle is increased), so that the position of the axial direction of the pay-off drum 3 is adjusted and controlled, the included angle between the axial direction of the pay-off drum 3 and the paid-off steel wire or steel belt is changed, and the tension of the steel wire or steel belt is controlled within the set range.
The invention has the following beneficial effects:
(1) the tension control method is different from the conventional tension control method in the conventional winding processing, and starts from the angle of controlling the paying-off speed and position of the stranding cage paying-off drum to control the tension fluctuation of the steel belt/steel wire. The innovation point is novel, and the thought is broad.
(2) The invention takes a plurality of influence factors and external interference of tension control in the flexible pipe tensile armor layer processing into consideration, and has an important effect on improving the tension control precision in the armor layer processing.
(3) The invention has simple structure, obvious effect and easy processing and manufacturing.

Detailed Description
The present invention is further illustrated by the following specific examples.
Assuming that the position of the pay-off drum 3 is on the left of the initial center position of the pay-off drum 3 at a certain moment, if the detected tension of the steel wire/steel strip is higher than the set tension fluctuation range, the hydraulic/worm drive device 13 moves the pull motor and the speed reducer B12 to a direction close to the initial center position of the pay-off drum 3 or to a direction reducing the pay-off angle (an included angle (acute angle or right angle) formed by the axial direction of the pay-off drum 3 and the paid-off steel wire or steel strip when paying off the pay-off drum 3), i.e., to move to the right by a certain displacement. At the same time, the motor and reducer a11 and the motor and reducer B12 accelerate to a certain extent, and finally, the tension is maintained within the set tension range. At this time, if the detected tension of the steel wire/steel strip is lower than the set tension fluctuation range, the hydraulic/worm driving device 13 moves the pushing motor and the speed reducer B12 in a direction away from the initial center position of the pay-off drum 3 or in a direction that increases the pay-off angle (an included angle (acute angle or right angle) formed by the axial direction of the pay-off drum 3 and the paid-off steel wire or steel strip when the pay-off drum 3 is paying off), that is, moves a certain displacement to the left. At the same time, the motor and reducer a11 and the motor and reducer B12 decelerate to a certain extent, and finally maintain the tension within the set tension range.
Assuming that the position of the pay-off drum 3 is located at the right side of the initial central position of the pay-off drum 3 at a certain moment, if the detected tension of the steel wire/steel strip is higher than the set tension fluctuation range, the hydraulic/worm driving device 13 will move the pushing motor and the speed reducer B12 to the direction close to the initial central position of the pay-off drum 3 or to the direction increasing the pay-off angle (the included angle (acute angle or right angle) formed by the axial direction of the pay-off drum 3 and the paid-off steel wire or steel strip when paying off the pay-off drum 3), i.e. to the left side. At the same time, the motor and reducer a11 and the motor and reducer B12 accelerate to a certain extent, and finally, the tension is maintained within the set tension range. At this time, if the detected tension of the steel wire/steel strip is lower than the set tension fluctuation range, the hydraulic/worm driving device 13 moves the pulling motor and the speed reducer B12 in a direction away from the initial center position of the pay-off drum 3 or in a direction that reduces the pay-off angle (the included angle (acute angle or right angle) formed by the axial direction of the pay-off drum 3 and the paid-off steel wire or steel strip when the pay-off drum 3 is paying off), i.e., moves a certain displacement to the right. At the same time, the motor and reducer a11 and the motor and reducer B12 decelerate to a certain extent, and finally maintain the tension within the set tension range.
The following summarizes the control actions and modes of the tension control device when the whole device is faced with different working conditions, and the following table is specifically provided.
The above examples merely represent embodiments of the present invention and are not to be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
