Description

Technical Field

[0001] This utility model relates to the field of cable-laying vessels, and in particular to a reciprocating cable-laying and positioning device with a rotating cable reel. Background Technology

[0002] Cable-laying vessels are core engineering vessels specifically designed for the laying, repair, and maintenance of submarine cables and optical fibers, playing an irreplaceable role in fields such as marine communications, energy transmission, and national defense. During cable-laying operations, the rotating cable reel positioning device is a crucial piece of equipment used to assist in the rapid and precise loading or unloading of cables from the rotating cable hull.

[0003] Traditional cable loading and unloading methods rely heavily on manual operation or simple mechanical assistance, resulting in low efficiency and poor safety. Currently, the application of rotating cable pods offers a significant improvement in efficiency compared to manual cable winding. For example, utility model patent CN203079420U discloses a cable storage and deployment device suitable for long-distance deep-sea hose laying. This device includes a frame assembly, a power system, a control system, a hose bracket, a tensioner, a cable laying device, and a rotating cable storage pool. The frame assembly contains a power system including, but not limited to, a generator and a hydraulic power station. The upper part of the frame assembly houses a control system including, but not limited to, an electrical control box. The upper part of the frame assembly also sequentially includes the hose bracket, tensioner, and cable laying device. The rotating cable storage pool, driven and controlled by the power and control systems, is located outside the frame assembly. This device can be easily installed on large transport vessels and, in conjunction with hose laying traction and guiding equipment, can independently complete long-distance deep-water hose construction, saving project construction costs.

[0004] However, the above technology mainly relies on the swing of the cable feeder's rotating mechanism to feed the cable into the rotating cable reel in sequence. At this time, the swinging arm needs a large safety space, so a safer and more reliable return device is required. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a reciprocating cable placement device for a rotating cable reel, which can achieve the placement of cables in the rotating cable reel without the need for the device to swing itself, and provides sufficient protection for the cable transportation, making it safer and more reliable.

[0006] To achieve the above objectives, this application discloses a reciprocating cable placement device for a rotating cable reel, comprising: a reciprocating cable placement device fixedly disposed above the rotating cable reel; a cable placement machine disposed on one side of the reciprocating cable placement device, the cable placement machine providing power for loading and unloading cables into and out of the rotating cable reel; the reciprocating cable placement device includes a track disposed on a support, the track supporting and constraining the movement of the reciprocating cable placement mechanism and the movable array cable support frame; the reciprocating cable placement mechanism is driven by a steel wire rope driven by a linear reciprocating drive winch disposed on the support; the movable array cable support frame is composed of several cable support frame units, any two adjacent cable support frame units are connected by a chain, and the movable array cable support frame is connected to the reciprocating cable placement mechanism by a chain; the cable placement machine, the movable array cable support frame, and the reciprocating cable placement mechanism are configured to guide the cables into the rotating cable reel.

[0007] Furthermore, the cable support unit is equipped with transverse and longitudinal rollers to support and protect the cable.

[0008] Furthermore, the front and rear ends of the reciprocating cable laying mechanism are respectively fixedly connected to the two ends of the wire rope disposed on the linear reciprocating drive winch.

[0009] Furthermore, the included angle between the two sets of cable inlets and outlets on both sides of the reciprocating cable laying mechanism is 90°, and support rollers are provided inside the cable inlets and outlets and the reciprocating cable laying mechanism.

[0010] Furthermore, the bottom of the reciprocating cable laying mechanism and the moving array cable support frame are respectively provided with cable laying mechanism travel pulleys and cable support frame travel pulleys.

[0011] Furthermore, the wire rope is supported and its direction is changed by a fixed pulley set on the support.

[0012] Furthermore, the rotating cable reel is driven to rotate by several drive motors located at the bottom of the cable reel.

[0013] Furthermore, a strip-shaped opening is provided between the reciprocating cable laying device and the rotating cable reel to guide the cable in and out of the rotating cable reel.

[0014] Furthermore, an inspection ladder is provided on the outside of the reciprocating cable laying device, and a cable guide frame is provided on the outside of the cable laying machine.

[0015] The reciprocating cable placement device with a rotating cable reel provided by this utility model has the following advantages:

[0016] High safety and small footprint: The linear reciprocating motion replaces the traditional swing arm rotation motion, eliminating the need to reserve a large rotation safety space for the swing arm. The structure is more compact, which has obvious advantages in the limited space of the ship's cabin. In addition, the trajectory of the linear motion is more controllable, resulting in higher safety.

[0017] Precise cable laying and high degree of automation: By controlling the rotation speed of the cable reel and the moving speed of the reciprocating cable laying mechanism, the cables can be laid in a precise, neat and tight spiral pattern, which improves the loading rate of the cable pod. The whole process is automated, reducing the intensity and risk of manual operation.

[0018] Comprehensive cable protection: From the moving array cable tray to the reciprocating cable laying mechanism, horizontal and vertical rollers are installed throughout the entire process to provide continuous support and guidance for the cables, effectively preventing dragging, wear, and scratches on the cable sheath. In particular, the 90° turning design inside the reciprocating cable laying mechanism scientifically protects the minimum bending radius of the cables, preventing permanent damage.

[0019] Reliable structure and easy maintenance: The overall structural design is reasonable, and the drive method is simple and reliable. The combination of linear reciprocating drive winch and wire rope is a mature and reliable drive technology. All components are easy to inspect and maintain, and the included inspection ladder also facilitates daily maintenance. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1 to 8 This utility model provides a reciprocating cable laying and positioning device for a rotating cable reel, including: a rotating cable reel 100, a reciprocating cable laying device 200 disposed above it, and a cable laying machine 300 disposed on one side of the reciprocating cable laying device 200.

[0032] During cable loading operations, the cable laying machine 300 provides the driving force for conveying the cable 400, feeding the cable 400 into the reciprocating cable laying device 200; during cable unloading operations, the cable laying machine 300 provides reverse traction or braking force to orderly extract the cable 400 from the rotating cable reel 100. To facilitate the introduction of the cable 400, a cable guide frame 600 can also be installed on the outside of the cable laying machine 300 to provide initial guidance and support for the cable 400.

[0033] The rotating cable reel 100 is the main structure for storing cables 400, and it mainly consists of a large circular cable reel 110. Several drive motors 120 are evenly arranged at the bottom of the cable reel 110. These drive motors 120 drive the entire rotating cable reel 100 to rotate around its central axis through gear transmission or other means. By precisely controlling the speed and direction of the drive motors 120, the rotating cable reel 100 can rotate smoothly and at a uniform speed. Combined with the linear motion of the reciprocating cable arrangement device 200, the cables 400 are arranged in a neat spiral pattern within the cable reel 110.

[0034] The reciprocating cable laying device 200 is the core component for achieving precise positioning of the cable 400 in the radial direction of the rotating cable reel 100. This device is fixedly mounted on the hull structure, spanning across the rotating cable reel 100. Figure 2 As shown, the reciprocating cable laying device 200 mainly includes a sturdy support 201, on which a track 202 is laid in parallel. The track 202 is used to support and guide the reciprocating cable laying mechanism 210 and the moving array cable support frame 220 to move linearly back and forth on it. An inspection ladder 240 is also provided on the support 201 to facilitate daily inspection and maintenance of the equipment by the staff.

[0035] Please see Figure 2-8 The movement of the reciprocating cable laying mechanism 210 is achieved by a linear reciprocating drive winch 230 located at one end of the support 201. The two ends of the wire rope 231 wound on the winch 230 drum are fixedly connected to the front and rear ends of the reciprocating cable laying mechanism 210, respectively. Specifically, one end of the wire rope 231 is directly connected to one end of the reciprocating cable laying mechanism 210, while the other end passes over several fixed pulleys 203 located at the other end of the support 201 before connecting to the other end of the reciprocating cable laying mechanism 210. When the linear reciprocating drive winch 230 rotates in the forward direction, the wire rope 231 at one end is wound, pulling the reciprocating cable laying mechanism 210 towards the winch direction; simultaneously, the wire rope 231 at the other end is released. When the winch 230 rotates in the reverse direction, the pulling and releasing are reversed, thereby driving the reciprocating cable laying mechanism 210 to smoothly perform linear reciprocating motion on the track 202. The bottom of the reciprocating cable laying mechanism 210 is provided with a cable laying mechanism travel pulley 213. The pulley 213 cooperates with the track 202 to reduce the frictional resistance during movement and ensure the smoothness of movement.

[0036] The reciprocating cable laying mechanism 210 is the last guiding unit before the cable 400 enters the rotating cable reel 100. Its structure is as follows: Figure 3 As shown, a box-shaped structure has two sets of cable inlet / outlet ports 211 on both sides, with the included angle between the axes of these two sets of cable inlet / outlet ports 211 being 90°. The horizontal cable inlet / outlet ports 211 are used to receive cables 400 conveyed from the moving array cable tray 220, while the vertically downward cable inlet / outlet ports 211 guide the cables 400 to the rotating cable reel 100 directly below. To protect the cables 400 from damage during turning and to ensure smooth turning, multiple support rollers 212 are arranged inside the reciprocating cable arrangement mechanism 210 along the path of the cables 400. These rollers 212 form a smooth arc transition, ensuring that the bending radius of the cables 400 is always greater than its minimum allowable bending radius.

[0037] Please see Figure 2 and Figure 8The function of the mobile array cable support 220 is to provide continuous and reliable support for the cable 400 between the cable laying machine 300 and the moving reciprocating cable laying mechanism 210. It consists of several identical cable support units 221 connected in series. Any two adjacent cable support units 221 are flexibly connected by a chain 222. The last cable support unit 221 is connected to the reciprocating cable laying mechanism 210 via a chain 222. Each cable support unit 221 is also equipped with a cable support pulley 225 at its bottom, allowing it to slide freely on the track 202. When the reciprocating cable laying mechanism 210 moves, it drives the entire mobile array cable support 220 to expand or contract on the track 202, similar to a retractable channel. Each cable support unit 221 is equipped with a transverse roller 223 and a longitudinal roller 224, which together form a U-shaped or nearly closed channel to constrain the cable 400. This not only supports the weight of the cable but also prevents it from excessively shifting or vibrating in the transverse and longitudinal directions, providing all-round protection.

[0038] Between the rotating cable reel 100 and the reciprocating cable laying device 200, a slot 500 is typically provided. This slot 500 is fixedly installed, and its length direction is consistent with the moving direction of the reciprocating cable laying mechanism 210. After the cable 400 exits from the lower outlet of the reciprocating cable laying mechanism 210, it passes through this slot 500 and then enters the rotating cable reel 100. This slot 500 serves as a final guide and protection, preventing debris from falling into the rotating cable reel 100.

[0039] Work process:

[0040] Taking the installation of cables into the cabin as an example, the working process is as follows:

[0041] Start the cable laying machine 300 to feed the cable 400 at a set speed. After the initial guidance of the cable guide frame 600, the cable 400 enters the moving array cable support frame 220.

[0042] The cable 400 is conveyed to the reciprocating cable laying mechanism 210 under the full support and protection of the rollers 223 and 224 of the moving array cable support frame 220.

[0043] After the cable 400 enters the reciprocating cable laying mechanism 210, it is guided by the internal support roller 212, changes direction by 90°, and moves vertically downward.

[0044] Start the drive motor 120 of the rotating cable reel 100, so that the cable reel 110 starts to rotate at a preset low speed.

[0045] At the same time, the linear reciprocating drive winch 230 is started, driving the reciprocating cable laying mechanism 210 to move slowly along the track 202 from one end, for example, the outer edge, to the other end, the inner edge of the rotating cable reel 100.

[0046] Under the combined action of the rotational motion of the rotating cable reel 100 and the linear reciprocating motion of the reciprocating cable laying mechanism 210, the cable 400 is neatly coiled layer by layer in the cable reel 110 with a uniform pitch.

[0047] Throughout the process, as the position of the reciprocating cable laying mechanism 210 changes, the moving array cable support 220 automatically extends or shortens, always providing uninterrupted support for the cable 400.

[0048] The process of laying cables out of the cabin is the reverse of the process described above.

[0049] This utility model can be summarized in other specific forms that do not depart from the spirit or main features of this utility model. Therefore, in all respects, the above embodiments of this utility model should only be considered as descriptions of this utility model and not as limitations thereof. The claims specify the scope of this utility model, while the above description does not specify the scope of this utility model. Therefore, any changes within the meaning and scope equivalent to the claims of this utility model should be considered as included within the scope of the claims of this utility model.
