Description

Technical Field

[0001] The utility model relates to the field of offshore wind power, in particular to a pipeline centering clamping and transportation device. Background Art

[0002] Grouting vessels play a critical supporting and safeguarding role in various underwater and marine engineering projects, providing a crucial technical means to ensure the long-term stability and safety of these projects. These vessels frequently transport and install large quantities of pipelines for the delivery of cement slurry and other fluids. Existing methods for transporting and assembling pipelines often rely on a combination of manual labor and heavy machinery.

[0003] Especially for large ships, the grouting pipes are often lifted by the ship's own crane or the extra-long pipes on board are extended to the seabed. This process is not only very demanding on the ship, but also often requires a large ship to complete the construction. In addition, both the large crane and the extra-long grouting pipes often occupy a very large space.

[0004] For medium-sized ships, grouting vessels are often not considered for the following reasons: To reach the specified depth and take into account the space on the ship, these pipelines are usually composed of pipe sections spliced together and connected by threads or flanges. To install and remove the pipelines, workers need to use lifting equipment such as small cranes to move the pipelines and use tools to manually tighten the bolts between the pipelines to achieve connection or removal. There are many problems in this process:

[0005] Manual operations are complex and laborious. Workers operate under scorching sun or in harsh environments, exerting significant physical exertion and easily fatigued, impacting work efficiency and safety. Personnel must constantly move the pipes to the installation location and then manually rotate and install them using tools, which is time-consuming and labor-intensive. During the pipe lifting and rotation process, heavy pipes are prone to shifting or falling, posing a serious safety hazard to workers on site. Any errors can result in material loss and casualties, increasing the difficulty and risk of construction. Existing manual installation and removal methods are inefficient, slow, and unable to meet the demands of efficient large-scale pipe installation. The pipe connection process requires numerous steps, each requiring a high level of coordination, which prolongs construction time. Labor costs are high, as the complex operation requires specialized personnel for each step, further increasing labor costs. These high costs and labor intensity make the entire construction process more expensive and inefficient.

[0006] Based on the above problems, the applicant came up with the idea of developing an automatic transport and assembly system for grouting pipes on board ships. The system includes a grouting ship carrier, a pipe clamping and lifting transport device, a pipe centering clamping transport device, and a pipe assembly and docking device. The system adopts a modular design, with each module performing transport-positioning-assembly and disassembly tasks separately. By threading the pipe sections together, the system enables automatic installation and disassembly of the pipes, significantly improving the automation level and overall work safety at the construction site. Furthermore, the system takes up less space and is suitable for small and medium-sized grouting ships. The pipe centering clamping transport device centers, clamps, and transports the pipes forward, but the structural design and functional implementation of the pipe centering clamping transport device remain a challenge. Utility Model Content

[0007] The purpose of the utility model is to provide a pipeline centering clamping and transportation device to solve the problems raised in the above background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] A pipeline centering clamping and transportation device includes a horizontal sliding support mechanism and two groups of belt flipping conveying mechanisms located on the left and right sides of the horizontal sliding support mechanism, respectively. The horizontal sliding support mechanism is used to slide and support the pipeline. The belt flipping conveying mechanism includes a belt conveyor arranged along the front and back directions and a flipping driver for driving the belt conveyor to flip. When the left and right groups of belt conveyors flip to a vertical state, they jointly clamp the pipeline and use the belt to drive the pipeline to move forward and backward.

[0010] Furthermore, the horizontal sliding support mechanism includes a horizontal guide support frame and a row of support rollers arranged on the horizontal guide support frame at intervals along the front-to-back direction. The axes of the support rollers are set along the left-right direction. When the belt conveyor is flipped to a vertical state, the position of the belt conveyor is higher than the position of the support rollers.

[0011] Furthermore, the belt flipping conveying mechanism also includes a belt support frame, the belt support frame is rotatably arranged, the belt conveyor is arranged on the belt support frame, and the flipping driver is connected to the belt support frame to drive the belt support frame to flip.

[0012] Furthermore, it also includes a pipe centering clamping base, the horizontal sliding support mechanism and the belt flipping conveying mechanism are both arranged on the pipe centering clamping base, the belt support frame and the flipping drive are both rotatably connected to the pipe centering clamping base, and the flipping drive is rotatably connected to the belt support frame.

[0013] Furthermore, the tilting driver is a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0014] Furthermore, the left and right groups of the horizontal sliding support mechanism belt flipping conveying mechanisms are symmetrically arranged.

[0015] Compared with the existing technology, the beneficial effects of the present invention are: on the one hand, the present invention uses a horizontal sliding support mechanism to support the pipeline and provide sliding support for the forward and backward movement of the pipeline; on the other hand, it uses a belt flipping conveying mechanism to clamp the pipeline and drives the pipeline to move forward and backward through the belt, thereby realizing the centered clamping and conveying of the pipeline. It has the advantages of reasonable design, simple and compact structure, and high working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 3 A pipe centering clamping and transportation device includes a pipe centering clamping base 500, on which a horizontal sliding support mechanism and two groups of belt flipping conveying mechanisms are respectively located on the left and right sides of the horizontal sliding support mechanism. The left and right groups of belt flipping conveying mechanisms are symmetrically arranged. The horizontal sliding support mechanism is used to slide and support the pipe 2. The belt flipping conveying mechanism includes a belt conveyor 504 arranged along the front and rear directions and a flip driver 505 for driving the belt conveyor 504 to flip. When the left and right groups of belt conveyors flip to a vertical state, they jointly clamp the pipe 2 and use the belt to drive the pipe 2 to move forward and backward.

[0022] It can be understood that in the above technical solution, the utility model uses a horizontal sliding support mechanism to support the pipeline 2 and provide sliding support for the forward and backward movement of the pipeline 2 on the one hand, and uses a belt flip conveying mechanism to clamp the pipeline 2 and drive the pipeline 2 to move forward and backward through the belt, thereby realizing the centering clamping and conveying of the pipeline 2, which has the advantages of reasonable design, simple and compact structure, and high working efficiency.

[0023] Continue reading Figure 1 and Figure 2 In one embodiment of the present invention, the horizontal sliding support mechanism includes a horizontal guide support frame 501 and a row of support rollers 502 spaced apart along the front-to-back direction on the horizontal guide support frame 501. The axes of the support rollers 502 are arranged along the left-to-right direction. When the belt conveyor 504 is flipped to a vertical position, the position of the belt conveyor 504 is higher than the position of the support rollers 502. The pipe 2 is supported on the support rollers 502 and slides back and forth on the support rollers 502.

One end of the flipping driver 505 is rotatably connected to the middle part of the belt support frame 503, and the other end is rotatably connected to the central clamping base 500 of the pipe, which drives the belt support frame 503 to flip.

[0025] The tilting drive 505 is preferably a hydraulic cylinder, and may also be a pneumatic cylinder or an electric cylinder.

[0026] When the present invention is working, the pipeline 2 is transported to the pipeline centering clamping and transporting device 5 by the pipeline clamping and lifting transport device 4. The pipeline 2 is placed horizontally with its axis facing forward and backward. Then the flip drivers 505 on the left and right sides drive the belt conveyors 504 on the same side to flip to a vertical state and fit tightly against the side of the pipeline 2. The belt conveyors 504 on both sides are used to clamp the pipeline 2 so that the pipeline 2 is centered. In this way, the pipeline 2 can accurately enter the next work station. At the same time, the belt conveyor 504 is working, and its belt drives the pipeline 2 to move forward.
