Description

Technical Field

[0001] The utility model relates to the field of offshore wind power, in particular to a carrier device for a grouting ship. 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 thought of developing an automatic transportation and assembly and disassembly system for grouting pipes on board ships. The system includes a grouting ship carrier device, 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. Each module performs transportation-positioning-assembly and disassembly work respectively. By threading the pipes one by one, the automatic installation and disassembly of the pipes can be realized, which can greatly improve the automation level and overall work safety of the construction site. It also takes up less space and is suitable for small and medium-sized grouting ships. Among them, the grouting ship carrier device plays the role of carrying the pipe clamping and lifting transport device, the pipe centering clamping transport device, and the pipe assembly and docking device. In addition, the pipe assembly and docking device needs to be extended outside the grouting ship when working and should be located inside the grouting ship when not working. This requires the grouting ship carrier device to move it. However, how to achieve the carrying, movement and parking of the grouting ship carrier device is a tricky problem. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0024] See also Figures 1-4A carrier vehicle device for a grouting ship includes a carrier vehicle 300 and a power vehicle 301 connected thereto. The power vehicle 301 drives the carrier vehicle 300 to move forward and backward. A plurality of parking mechanisms are evenly arranged on the bottom of the power vehicle 301. The parking mechanisms include a telescopic rod 3011, an electromagnet 3012 and an elastic element 3013. The telescopic rod 3011 and the power vehicle body 3010 of the power vehicle 301 are telescopically and slidably matched up and down. The electromagnet 3012 is arranged at the lower end of the telescopic rod 3011. The elastic element 3013 is connected between the power vehicle body 3010 and the electromagnet 3012. The elastic element 3013 pulls the electromagnet 3012 upward. When the electromagnet 3012 is energized, it is adsorbed on the magnetic deck.

[0025] The carrier vehicle 300 carries the pipe clamping and lifting transport device 4, the pipe centering clamping and transport device 5, the pipe assembly and docking device 6, and other devices. It moves on the deck rails 100. The power vehicle 301 has wheels and a conventional wheel drive device. The power vehicle 301 can automatically drive and push and pull the carrier vehicle 300, driving the carrier vehicle 300 back and forth.

[0026] Among them, when the carrier device is traveling, the electromagnet 3012 is not energized. Under the action of the elastic element 3013, the electromagnet 3012 is away from the deck. When the carrier device stops, in order to prevent the carrier device from slipping, the electromagnet 3012 is energized. The electromagnet 3012 overcomes the force of the elastic element 3013 and is adsorbed on the magnetic deck, thereby achieving parking.

[0027] In the above technical solution, the carrier device of the present invention carries the clamping and lifting transport device 4, the pipeline centering clamping transport device 5, the pipeline assembly docking device 6 and other devices through the carrier vehicle 300, and drives the carrier vehicle 300 to move forward and backward through the power vehicle 301, so that the front end of the carrier vehicle 300 can extend out of the deck and retract into the deck. In addition, the power vehicle 301 also realizes automatic parking through the parking mechanism to avoid slipping of the carrier device during the pipeline assembly process.

[0028] Continue reading Figure 2 The elastic element 3013 is a tension spring, which is sleeved on the telescopic rod 3011.

[0029] In another embodiment of the present invention, the elastic element 3013 may also be a compression spring, which is located in the power vehicle body 3010 and pushes the telescopic rod 3011 upward, which can also keep the electromagnet 3012 away from the deck.

[0030] Furthermore, the elastic element 3013 is a conductive coil, which can conduct electricity and also act as a tension spring.

[0031] It should be noted that the number and positions of the parking mechanisms can be adjusted as needed.

[0032] Continue reading Figure 3 The carrier vehicle 300 includes a carrier body 3000, and a transverse roller 3001 is set at the lower end of the carrier body 3000. The axis of the transverse roller 3001 is set horizontally, which cooperates with the deck. A vertical roller 3002 is set on the side of the carrier body 3000, and the axis of the vertical roller 3002 is set vertically, which cooperates with the track 100.

[0033] Further reading Figure 3 Two rows of horizontal rollers 3001 are set at the lower end of the carrying body 3000, and a row of vertical rollers 3002 are set on the left and right sides of the carrying body 3000 respectively. The vertical rollers 3002 are located on the outside of the horizontal rollers 3001 on the same side and are positioned higher than the horizontal rollers 3001.

[0034] Further reading Figure 3 , the left and right sides of the carrying body 3000 are provided with limiting grooves 3003, and the limiting grooves 3003 are used to cooperate with the limiting protrusions 1000 on the track 100. This can avoid derailment.

[0035] Continue reading Figure 1 The carrier vehicle 300 is provided with a notch 3004 , and when the pipeline 2 is assembled, the notch 3004 allows the pipeline 2 to pass through and extend into the seawater.
