Description

Technical Field

[0001] This utility model relates to the field of marine technology, specifically to a marine pipeline support device. Background Technology

[0002] In shipbuilding and maintenance, pipeline laying and securing is a critical process, and its installation quality directly affects the safety and reliability of the ship's systems. Traditional ship pipeline supports mostly use fixed bracket structures, which suffer from poor adjustment flexibility and low installation efficiency. Especially in narrow compartments or complex piping layouts, construction personnel often need to spend a lot of manpower adjusting pipeline positions, and even improper support angles can lead to pipeline twisting or stress concentration, affecting system lifespan. In addition, most existing support devices cannot adapt to pipelines of different diameters, resulting in poor versatility and increased equipment costs and storage pressure. Although some adjustable support structures have been reported, their adjustment mechanisms are complex, inconvenient to operate, and lack effective angle locking and auxiliary labor-saving designs, making it difficult to meet the needs of efficient assembly in modern ships. Therefore, there is an urgent need for a ship pipeline support device with a reasonable structure, convenient operation, flexible adjustment, and labor-saving functions to improve pipeline laying efficiency and quality. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses a ship pipeline support device. The technical solution adopted includes a fixed base plate, fixing bolts, and vertical fixing plates, all of which are conventional accessories. The device also includes a rotating structure, mounting plate, mounting groove, fixing shaft, adjusting part, fitting plate, and inclined support plate. The fixed base plate is fixed to the installation position by fixing bolts. Vertical fixing plates are integrally formed on the front and rear sides of the fixed base plate. A rotating structure is set between the vertical fixing plates. The mounting plate is installed through the rotating structure. The advantage of the rotating structure is that it allows the pipeline to be pulled. After being pulled halfway, the angle of the mounting plate can be changed by the rotating structure, causing it to tilt, thus making the pipeline pulling process easier and more efficient. The mounting plate has three mounting grooves. The fixing shaft is fixedly installed in the mounting grooves on the left and right sides, and the adjusting part is set in the middle mounting groove. The fitting plate is movably fitted with the fixing shaft and installed in conjunction with the adjusting part. An inclined support plate is fixedly installed on the fitting plate. The distance between the two inclined support plates is adjusted by operating the adjusting part according to the diameter of the pipeline being pulled, thus meeting the pipeline support requirements.

[0004] As a preferred embodiment of this utility model, the rotating structure includes a rotating shaft, a front circular plate, an arc-shaped notch, and limiting screws. A vertical fixing plate has through holes in the front-to-back direction. The rotating shaft passes through two through holes, with both ends extending outwards. The front circular plate is fixed at the front end, and the limiting plate is fixed at the rear end. Both the front circular plate and the limiting plate are in contact with the side of the vertical fixing plate. The side of the front circular plate has symmetrical arc-shaped notches. The front side of the vertical fixing plate has four screw holes for installing the limiting screws. The limiting screws are located within the arc-shaped notches and each contacts the inner wall of the arc-shaped notch. The mounting plate is fixed on the rotating shaft. Initially, the two arc-shaped notches are symmetrical. The positions of the four limit screws form a rectangle with the center of the front circular plate as the center. When the mounting plate needs to rotate, first remove the limit screw in the lower right corner, and then remove the limit screw in the upper left corner. At this time, the front circular plate loses its limit. Under the action of gravity, the mounting plate tilts, and the rotating shaft also rotates. However, the rotation angle of the rotating shaft is limited by the two limit screws that have not been removed. That is, the rotation stroke is the angle of the arc-shaped notch, which limits the tilt angle to avoid excessive tilt.

[0005] As a preferred technical solution of this utility model, the adjustment part includes a central rotating shaft and a knob. The front and rear sides of the central mounting groove have through holes. The central rotating shaft passes through the two through holes and extends out at both ends. The knob is fixed at the front end and the limiting plate is fixed at the rear end. Both the fixed knob and the limiting plate are in contact with the side of the mounting plate. The outer wall of the central rotating shaft is provided with symmetrical threaded grooves. The central mounting plate is installed in conjunction with the threaded grooves. The outer wall of the knob is provided with anti-slip grooves. When the knob is manually rotated, the inclined plates on the front and rear sides move closer or further apart under the action of the symmetrically arranged threaded grooves, and the adjustment distance meets the requirements for pipeline support placement.

[0006] As a preferred technical solution of this utility model, the inclined support plate has several through slots, and rollers are rotatably installed in the through slots.

[0007] As a preferred technical solution of this utility model, a groove is cut in the middle of the base plate in the left and right directions. Two baffles are fixed on the lower surface of the mounting plate, and a shaft is fixed between the baffles. One end of the auxiliary support rod is fitted with the shaft, and the lower end extends into the groove. The side of the auxiliary support rod contacts the inner wall of the baffle. A tightening screw is installed on the left side of the base plate. The right end of the tightening screw extends into the groove, and its right end is fixed to the right end plate. The right end plate is movably placed in the T-shaped arc groove on the left side of the top plate.

[0008] The beneficial effects of this utility model are as follows: By setting a rotating structure, the mounting plate can be tilted when the pipeline is pulled halfway, and the pipeline angle can be naturally changed by gravity, which significantly reduces the resistance of manual traction, makes the pipeline introduction process more labor-saving, and greatly improves the laying efficiency; the support spacing is flexible and adjustable, and has strong versatility; the arc-shaped notch of the rotating structure cooperates with the limit screw, which allows the mounting plate to rotate freely within a certain angle range to adapt to the operation requirements, and prevents its tilt angle from being too large through mechanical limit.

[0014] As a preferred technical solution of this utility model, the inclined support plate 13 has several through slots 14, and a roller 15 is rotatably installed in the through slots 14.

[0015] As a preferred technical solution of this utility model, a groove 2 is cut in the middle of the fixed base plate 1 in the left and right directions. Two baffles 71 are fixed on the lower surface of the mounting plate 7. A shaft is fixed between the baffles 71. One end of the auxiliary support rod 16 is fitted with the shaft, and the lower end extends into the groove 2. The side of the auxiliary support rod 16 contacts the inner wall of the baffle 71. A tightening screw 17 is installed on the left side of the fixed base plate 1.

The right end plate 172 is movably placed in the T-shaped arc groove 171 cut on the left side of the top plate 18.

[0016] The working principle of this utility model is as follows: During use, the fixed base plate is securely installed at a predetermined position on the ship's pier using fixing bolts, forming the supporting foundation for the entire device. During installation, the device's orientation can be initially determined based on the approximate route of the pipeline. When the pipeline is laid, the initial mounting plate remains horizontal under the support of the rotating structure. The two ends of the rotating shaft of the rotating structure are supported by vertical fixing plates, and the mounting plate is locked in a horizontal position by limiting screws engaging with the arc-shaped notch on the front circular plate, providing an initial, stable platform for the pipeline. When the pipeline is pulled in to a certain length and the resistance increases, the limiting of the rotating structure can be released: loosen and remove the two limiting screws located diagonally (e.g., the upper left and lower right). At this time, under the action of the pipeline's gravity and traction force, the mounting plate can freely rotate around the rotating shaft within a certain angle (determined by the remaining stroke of the arc-shaped notch), thus tilting. This tilt changes the pipeline's introduction angle, effectively utilizing the component of gravity to offset some of the frictional resistance, making subsequent traction operations more effortless. After the mounting plate is tilted, the new angle can be maintained using the remaining limit screws or auxiliary support rods to ensure stability. The upper end of the auxiliary support rod is connected to the mounting plate, and the lower end extends into the groove of the fixed base plate. By tightening the tightening screws, the right end plate at its right end can press against the auxiliary support rod, thereby providing additional support and enhancing stability.

[0017] For pipelines of different diameters, the distance between the two inclined support plates needs to be adjusted using an adjustment mechanism. During operation, a knob is manually rotated, causing the central shaft to rotate. Because the central shaft has symmetrical threaded grooves machined on it, and the inner hole of the mounting plate mates with these grooves, the two mounting plates move synchronously in opposite directions when the shaft rotates. This causes the inclined support plates fixed to them to approach or separate, achieving stepless adjustment of the support distance. After adjusting to the appropriate distance for the pipe diameter, the pipeline will be securely supported between the two inclined support plates. Finally, during the final insertion and fine-tuning of the pipeline, the rollers fixed to the inclined support plates begin to function. These rollers convert the sliding friction between the pipeline and the support plates into rolling friction, greatly reducing the traction force and wear on the outer surface of the pipeline during operation, thus providing effective protection.
