A line stretching shaft

Abstract

The present invention proposes a line stretching shaft comprising a support device, a first tray mechanism mounted on the support device, the first tray mechanism configured to rotate axially; and a rotating drum connected to the first tray mechanism, the drum being provided with a plurality of hairspring holes for passing through a pipeline bundle. The individual pipelines and hairsprings forming the pipeline bundle pass through the hairspring holes. The tensile force of the pipeline bundle generates a torque on the rotating drum, causing it to rotate on the first tray mechanism to adapt to the stretching angle of the pipeline bundle. This invention connects multiple pipelines through a single device, resulting in a safe and reliable line stretching shaft with high operational efficiency and reduced safety risks.

Description

Technical Field

[0001] The invention relates to a line stretching rotating shaft, belonging to the field of oil and gas exploration or other construction fields requiring line stretching and erection within a limited height. Background Art

[0002] During on-site installation of comprehensive mud logging, various sensor signal transmission lines—including those for density, temperature, conductivity, flow, carbon monoxide, hydrogen sulfide, as well as gas pipelines, power lines, and communications lines—are bundled together and then hoisted across a specific length, ranging from 30 to 50 meters or more. This line erection requires support, and because there's no better method or readily available equipment, two rods (struts) are used to support each end. These rods are then tensioned and straightened with a spring, and then tied together to a mast, resulting in a tangled and tortuous line.

[0003] During this installation process, the degasser's gas pipeline is a hollow rubber tube. This tube can become flat and deformed under compression, and in severe cases, it can completely close, blocking the gas path. This blockage can lead to missed oil and gas indications, and failure to detect oil and gas indications in a timely manner means no exploration benefits. Furthermore, because this method cannot automatically adjust to torsional forces, it often results in uneven stretching of the lines, and even wire breakage, interrupting signal transmission. This creates difficulties in daily work, increases labor intensity, and fails to effectively avoid operational risks.

[0004] In summary, without a scientific, professional and applicable device to standardize line installation, the following problems will arise: the line has large tensile torsional force, which is not conducive to line protection; the line has large tensile resistance, and the line support poles are easy to bend, which increases the equipment operating cost and reduces the equipment operating efficiency; the gas transmission line is easy to be blocked, affecting gas transmission; cross-operation is easy to be damaged, and re-installation increases labor intensity; the rigid winding of the power line is easy to form a large impedance, causing overcurrent, posing a safety hazard; the signal line, power line and gas pipeline cannot be scientifically and effectively separated, and interfere with each other; the line is easily damaged, affecting work efficiency. Summary of the Invention

The line stretching shaft is safe and reliable, has high operation efficiency, and reduces safety risks.

[0010] Among them, each pipeline and the hairspring form a pipeline bundle and pass through the hairspring perforation; the tensile force of the pipeline bundle generates torque on the rotating drum to rotate the rotating drum on the first tower plate mechanism to adapt to the tensile angle of the pipeline bundle.

[0016] A further improvement of the present invention is that a plurality of rotating wheel mechanisms are provided on the rotating drum, and each group of the hairspring perforations corresponds to one rotating wheel mechanism; the rotating wheel mechanism supports the pipeline bundle and reduces the friction force when the pipeline is stretched and moved by rotating.

[0017] A further improvement of the present invention is that the wheel mechanism includes a wheel support rod fixed to the rotating drum, and a wheel is provided in the middle of the wheel support rod;

[0025] In the line stretching shaft described in this invention, the tray mechanism achieves full rotation, and the cap-sleeved mounting system allows it to be used independently on other supports. The three-stage tray assembly avoids the limitations of conventional bearing structures, maximizing the ability to withstand full-scale tensile, compressive, and torsional forces. The rotor provides directional adaptability for load-bearing torque, and combined with tray rotation, reduces tensile stress. The upper and lower rotors can be used to stretch different lines, forming branch lines and enabling the connection of more lines. The capping structure provides support for auxiliary components such as weather vanes and warning lights, facilitating robust expansion applications. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] To make the technical solutions and advantages of the present invention more clearly understood, exemplary embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are only a portion of the embodiments of the present invention, and are not exhaustive. Furthermore, the embodiments and features of the embodiments of the present invention may be combined with each other unless there is a conflict.

[0034] Figure 1 A schematic diagram shows a line stretching shaft according to one embodiment of the present invention, comprising a support device 1, which is fixedly mounted and used to support other components. A first tray mechanism 2 is mounted on the support device 1. The first tray mechanism 2 is composed of multiple trays, with the bottom tray fixed to the support device 1, while the other trays are axially rotatable. A rotating drum 3 is connected to the first tray mechanism 2 and rotates with the trays. In this embodiment, the rotating drum 3 is provided with several spring holes 31 for passing through the pipeline bundle. The individual pipelines and springs form a pipeline bundle, which extends through the spring holes 31 to corresponding positions. When the pipeline bundle is stretched, the tensile force generates torque on the rotating drum 3. The rotating drum 3 rotates on the first tray mechanism 2 in response to this torque, adapting to the tensile force of the pipeline bundle and changing its angle to an optimal angle.

[0035] In one embodiment, Figure 2As shown, the support device 1 includes a support rod 11, which is a cylindrical structure with a plurality of threaded holes 13 provided on the side surface of its upper portion. The upper end of the support rod 11 is sleeved on a cap 12, which is a cylindrical structure including a cylindrical side surface and a circular top surface. The cap 12 is provided with a plurality of fastening threads 14, the number and size of the fastening threads 14 corresponding to the number and size of the threaded holes 13. The cap 12 is sleeved on the top of the support rod 11, the threaded holes 13 and the fastening threads 14 are aligned, and a fastening screw 15 is passed through to connect the support rod 11 and the cap 12. The bottom of the first tray mechanism 2 is fixedly provided on the cap 12.

[0036] In the line tensioning shaft described in this embodiment, six fastening holes 14 are provided on the side of the cap 12. The support rod 11 is a steel rod with an inner diameter slightly smaller than that of the cap 12 and a length adjusted as needed, seamlessly inserting into the cap 12. Six threaded holes 13 are provided on the side of the support rod 11. When the support rod 11 is inserted into the cap 12, the six threaded holes 13 symmetrically connect with the six fastening holes 14 on the cap 12 and are connected by fastening screws 15.

[0037] In one embodiment, Figure 3 As shown, the first tray mechanism 2 includes a first fixed tray 21, a second fixed tray 22, and a first rotating tray 23. The first fixed tray 21 is at the top, the second fixed tray 22 is at the bottom, and the first rotating tray 23 is disposed between the first fixed tray 21 and the second fixed tray 22. The first fixed tray 21, the second fixed tray 22, and the third fixed tray 43 are each provided with a connecting hole in their middle portions, through which a first connecting rod 25 passes to connect the first fixed tray 21, the second fixed tray 22, and the first rotating tray 23.

[0038] The second fixed tray 22 is connected to the support device 1 and is preferably welded to the cap 12. The first rotating tray 23 is fixedly connected to the drum 3 and can rotate relative to the first connecting rod 25. The connecting rod is fully welded to the top surface of the first fixed tray 21 and the bottom surface of the second fixed tray 22, forming a structure in which the fixed tray does not rotate and the rotating tray rotates.

[0039] A drum fixing hole 26 is provided on the side of the first rotating tower plate 23 , and the bottom of the rotating drum 3 is connected to the first rotating tower plate 23 through the rotating fixing hole 26 .

The ball grooves 24 of the first fixed tower plate 21 and the ball grooves 24 on the upper surface of the first rotating tower plate 23 are arranged opposite to each other, and the two ball grooves 24 have the same diameter, and a number of balls are arranged between the two.

[0041] The upper surface of the second fixed tray 22 is provided with a circle of ball rolling grooves 24, and the lower surface of the first rotating tray 23 is provided with a circle of ball rolling grooves 24 at a corresponding position.

A plurality of balls are arranged between the two ball rolling grooves 24.

[0042] According to the line stretching shaft described in this embodiment, by arranging ball grooves 24 and balls between the first fixed tower plate 21 and the first rotating tower plate 23, and between the second fixed tower plate 22 and the first rotating tower plate 23, friction can be reduced during the rotation of the first rotating plate, thereby making the rotating drum 3 rotate more conveniently.

The directions of the two groups of hairspring holes 31 can be consistent or inconsistent, depending on actual needs.

[0044] In one embodiment, the rotating drum 3 is provided with a plurality of rotating wheel mechanisms 32, one for each set of hairspring perforations 31. The tubing bundle passes through the hairspring perforations 31 and is attached to the rotating wheel mechanisms 32. The rotating wheel mechanisms 32 support the tubing bundle and rotate during the stretching and movement of the tubing bundle to reduce friction, allowing for smooth stretching or movement.

[0045] In one embodiment, the wheel mechanism 32 includes a wheel support rod 33 fixed to the drum 3. A wheel 34 is positioned in the middle of the wheel support rod 33. The wheel support rod 33 is oriented perpendicular to the direction of the pipe bundle. In this embodiment, the wheel support rod 33 has threads at both ends. The threads pass through the drum 3 and are secured with nuts. The wheel 34 has tapered wheels on both sides and a thinner structure in the middle to support the pipe bundle.

[0046] In one embodiment, a cover 4 is provided on the top of the drum 3. The cover 4 is a dome-shaped structure that closes the top of the drum 3 and is connected to the drum 3 via a thread. A screw handle 41 is provided on the cover 4 for screwing when installing the cover 4.

[0047] In one embodiment, Figure 4As shown, a second tray mechanism 42 is provided in the middle of the rotating drum 3. The second tray mechanism 42 includes a third fixed tray 43 and a fourth fixed tray 44. A second rotating tray 45 is provided between the third fixed tray 43 and the fourth fixed tray 44. The third fixed tray 43, the second rotating tray 45, and the fourth fixed tray 44 are connected by a second connecting rod 46. The second connecting rod 46 is provided with a hanging ring 47, which can be used to hang a warning light. In the line stretching shaft according to this embodiment, the second tray mechanism 42 can be used to connect or fix to other components.

[0048] In one embodiment, an inner wire tube 48 is provided on the side of the second rotating tower plate 45. Preferably, the inner wire tube 48 can be used to plug a wind vane, and a section of square steel is welded between the inner wire tube 48 and the plate circumference to extend the distance between the inner wire tube 48 and the plate circumference.

[0049] According to the line stretching shaft described in this embodiment, all-round rotation is achieved through the first tower plate mechanism 2 and the second tower plate mechanism 42, and the sleeve cap 12 is fixed in a sleeve manner so that it can be used alone on other supports; the three-stage tower plate combination avoids the application limitations of ordinary bearing structures and can withstand all-round tensile, compressive and torsional forces to the greatest extent.

[0050] The runner 34 provides directional adaptability for load-bearing torque, and combined with the tower plate rotation, reduces tensile stress. The upper and lower runners 34 can be used to stretch different lines, forming branch lines and allowing for more interconnected lines. The cover 4 structure provides support for auxiliary equipment such as wind vanes and warning lights, facilitating rigid expansion applications.
