Description

Technical Field

[0001] The present invention relates to a submarine optical and cable conveyor arranged on a construction ship or other construction platform for submarine optical and cable laying and burying facilities, in particular to a modular submarine cable conveyor which can be freely assembled in series. Background Art

[0002] With the vigorous development of the domestic wind power industry, submarine optical and electrical cable models are becoming more and more diversified, and the corresponding cable diameters are also very different. For a wind farm, there are often cables of various specifications and models, which requires the construction unit to be equipped with conveyors of different models to meet the cable laying needs of the wind farm. Especially after a wind farm project is completed or due to changes in engineering requirements, the cabling system needs to be transferred or dismantled, and traditional conveyors are large in size and relatively difficult to hoist and transport; replacing the special cabling machine corresponding to cables of different specifications requires the entire conveyor to be dismantled and replaced, which will consume a lot of manpower and material resources, resulting in the cost of replacing and transporting cable conveyors during construction.

[0003] In view of the above situation, a universal modular submarine cable conveyor is needed that can be formed for submarine optical and electrical cables of different specifications by simply adding or reducing some core modules to meet application requirements and solve the problem of difficulty in equipment disassembly, installation and transportation caused by frequent replacement of conveyors due to the diverse specifications of submarine cables to be laid. Summary of the invention

[0004] The present invention is to provide a modular submarine cable conveyor that can be freely assembled in series, so as to solve the problem of frequent replacement of submarine cable conveying equipment and the resulting difficulties in disassembly, installation and transportation of equipment when facing the construction of submarine cables of multiple specifications.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention to solve its technical problems is: a modular submarine cable conveyor that can be freely assembled in series, including a conveyor frame and a submarine cable clamping module; the submarine cable clamping module is divided into an upper clamping module and a lower clamping module, and the upper and lower clamping modules are connected by a cylinder module and connected to an equalizer; the submarine cable clamping module is placed in the conveyor frame to form a combinable independent submarine cable conveying module.

[0006] Furthermore, the upper clamping module and the lower clamping module of the submarine cable clamping module are both composed of a slider, a hydraulic motor, a coupling, a hub and a tire. The motor is arranged at the center of the slider and connected to the hub through a coupling. The tire is installed on the hub to form a wheel set.

[0007] Furthermore, the submarine cable clamping module is connected to the upper clamping module and the lower clamping module through the connecting bolt in the cylinder module. The cylinder barrel and the cylinder rod of the cylinder module can be extended and retracted. A pulley block of the equalizer is arranged in the conveyor frame. The wire rope of the equalizer passes through the pulley block and connects the upper and lower clamping modules through a wire rope connector.

[0008] Furthermore, when the cylinder module is extended or retracted, the steel wire rope of the equalizer is linked through the pulley block. After the steel wire rope is stressed, it will drive a pair of tires of the submarine cable clamping module in the conveyor to move towards each other to adjust the spacing between the tires, thereby effectively clamping the submarine cable.

[0009] Furthermore, the modular submarine cable conveyor relies on a pair of wheel groups on the submarine cable clamping module to clamp the submarine cable. The wheel group can operate independently. During the conveying process, the conveyor hydraulic motor can rotate at a uniform speed. The cable and the wheel group rely on friction to be transported at a uniform speed in the conveyor. The direction and speed of rotation of the wheel group are achieved by adjusting the speed and rotation direction of the hydraulic motor.

[0010] Furthermore, the modular submarine cable conveyor controls the return oil pressure of the hydraulic motor to achieve the function of controlling the submarine cable laying tension of the conveyor.

[0011] Furthermore, the combinable independent submarine cable conveying modules in the modular submarine cable conveyor can be used independently, or fixedly connected in pairs through bolt holes reserved in the side panels to form a serial conveyor array. The increase or decrease in the number of conveyor wheel groups can be achieved by serially stacking or separating modules, thereby meeting the needs of submarine cable laying construction for different types of submarine cables.

[0012] The beneficial effects of the present invention are:

[0013] 1. Each conveyor module of the present invention can operate independently, and the cable transmission tension can be changed by increasing or decreasing the number of modules according to the construction conditions. The change process only requires the disassembly and transportation of the increased or reduced conveyor modules, which greatly shortens the disassembly and assembly time and the manpower and material costs, and can solve the problems of conveyor disassembly and transportation difficulties caused by the frequent replacement of conveyors due to the diversity of cable specifications and sizes.

[0014] 2. Compared with the traditional closed-loop control principle of measuring the cable laying tension through sensors and controlling the conveyor speed through PID program, the modular submarine cable conveyor of the present invention does not require sensors, PLC, single-chip microcomputer, or computer industrial control. The principle is simple and reliable, avoiding the possibility of servo misoperation due to sensor failure, and is safe, reliable and controllable. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figures 1 to 3 As shown, the modular submarine cable conveyor 1 of the present invention is composed of a conveyor frame 2 and a submarine cable clamping module 3. The submarine cable clamping module 3 is embedded in the conveyor frame 2 and fixed by various partitions.

[0031] like Figure 4 As shown, the conveyor frame 2 is composed of a left side plate 8, a right side plate 9, a top plate 10, a bottom plate 11, a middle partition plate 12, a slider baffle 13, a front sealing plate 14, and a rear sealing plate 15. The left side plate 8 and the right side plate 9 are provided with side plate reserved bolt holes 16 for connecting the modular submarine cable conveyors 1 in series in pairs.

[0032] like Figure 5 As shown, the submarine cable clamping module 3 is composed of an upper clamping module 4, a lower clamping module 5, a cylinder module 6 and an equalizer 7. The cylinder module 6 connects the upper clamping module 4 and the lower clamping module 5. The equalizer 7 is responsible for adjusting the distance between the upper clamping module 4 and the lower clamping module 5 in conjunction with the cylinder module 6, thereby clamping the submarine cable.

[0033] like Figures 6 to 8 As shown, the upper clamping module 4 and the lower clamping module 5 of the submarine cable clamping module 3 rely on their own upper sliders 17 and lower sliders 18 to carry the hydraulic motor 19, as shown in FIG. Fig. 9 As shown, the upper slider 17 and the lower slider 18 are both provided with holes and installation positions of various connectors. One end of the hydraulic motor 19 passes through the hole and is fixed to the upper slider 17 and the lower slider 18 respectively by bolts 29, and is connected to the wheel hub 21 through a coupling 20. The cylinder rod 23 and the cylinder barrel 24 of the cylinder module 6 are respectively connected to the upper slider 17 and the lower slider 18 through connecting bolts 25. The wire rope 27 of the equalizer 7 is also connected to the upper slider 17 and the lower slider 18 through a wire rope connector 28. After the submarine cable 30 enters the modular submarine cable conveyor 1, the gap between the upper and lower tires 22 in the submarine cable clamping module 3 can be controlled by adjusting the cylinder module 6, so as to clamp the submarine cable 30; the tire 22 is driven by the hydraulic motor 19, and the friction between the tire 22 and the submarine cable 30 is used to enable the submarine cable 30 to move in the modular submarine cable conveyor 1.

[0034] like Figures 9 to 11 As shown, a plurality of modular submarine cable conveyors 1 can be connected by means of the reserved bolt holes 16 on the side panels to form a conveyor array.

[0035] like Figure 12 to Figure 14 As shown, when multiple modular submarine cable conveyors 1 form an array for operation, the conveyor array relies on multiple pairs of wheels to clamp the submarine cable 30 and provide sufficient tension. If the control tension needs to be increased during the construction process, the operating capacity can be expanded by installing a separate modular submarine cable conveyor 1; if the operating capacity is excessive, the modular submarine cable conveyor 1 can also be removed separately.
