At present, there are the following three problems in laying the cable:

[0003] 1. Cable outer skin damage problem: During the laying process, the cable rubs at the right angle of the outer plate top steel plate, and due to the sharp edge of the right angle part of the outer plate top steel plate, the cable outer skin is easily damaged, resulting in damage to the cable outer skin during the laying process.

[0004] 2. Outer plate paint damage problem: Due to the high freeboard of the ship, the laid cable is difficult to fix in the middle, so the cable laid along the outer plate of the ship is blown by the wind, thereby rubbing against the outer plate of the ship body, damaging the outer plate paint and affecting the appearance and corrosion resistance of the ship.

[0005] 3. Deck passage obstruction problem: Due to the lack of fixed lifting points on the ship's side, if a railing is used as a lifting point, the disordered cable will occupy the deck passage, affecting the smoothness of the passage, and thus affecting the passing efficiency of the construction personnel and equipment at the deck passage and increasing the moving risk.

[0055] In the embodiment, the left and right side plates are both stamping thin plates, and a plurality of lightening holes are arranged on the left and right side plates, so that the overall weight of the device is effectively reduced while the stability of the main structure 1 is maintained, and the manufacturing cost of the device is reduced; a plurality of transverse reinforcing ribs 11 are further arranged between the left and right side plates, the number of the transverse reinforcing ribs 11 is three, and the transverse reinforcing ribs 11 are all circular tubes, the left and right side plates are fixedly connected with two ends of the transverse reinforcing ribs 11 respectively, so that the main structure 1 is more stable and shaking during the process of pulling and covering is avoided; the vertical long plate 14 and the vertical short plate 13 are both reinforcing plates, so as to ensure the clamping force between the vertical long plate 14 and the vertical short plate 13.

[0058] S2, arrange the prepared cable 5, and install the device body at the edge position of the corresponding ship outer plate 6 to complete the fixed suspension of the device body.

[0059] S2-1, generally, the cable 5 is pulled and arranged by manpower, and the weight of the pulled and arranged cable 5 and the weight of the cable 5 suspended and fixed on the support rod 3 after the pulling and arranging are considered to prevent the deformation of the support rod 3, so that in the embodiment, when the cable 5 is arranged, the prepared cable 5 to be pulled and arranged is straightened in the wharf area, and according to the weight of the cable 5 itself and the bearing capacity of the support rod 3, the prepared cable 5 to be pulled and arranged is arranged into single cable 5 or multiple cables 5 in a bundle to prevent the winding of the cable 5 in the pulling and arranging process and prevent the deformation of the support rod 3.

[0060] S2-2, the installation steps of the device include: placing the device at the edge of the ship outer plate 6, suspending the outer edge by the protrusion of the edge of the ship outer plate 6, clamping the protrusion at the edge of the ship outer plate 6 between the vertical long plate 14 and the vertical short plate 13, and clamping and fixing the body and the protrusion at the edge of the outer plate 6 by the bolt fastener 4 on the vertical short plate 13, so that the back side of the vertical long plate 14 is attached to the outer side of the ship outer plate 6, thereby firmly fixing and suspending the device body at the top of the outer edge of the ship outer plate 6.

[0061] When the number of the cable 5 is single, the device is installed at the edge of the ship outer plate 6 between the cable 5 on the ship and the prepared laying position; when the number of the cable 5 is multiple in a bundle, that is, when a large number of cables 5 need to be on the ship, such as shore power cable 5, since the shore power cable 5 needs to be connected with the ship by single cable 5, a plurality of cables 5 need to be laid to be on the ship when connected with the shore power cable 5, at this time, according to the position of each cable 5 on the ship, a plurality of devices are arranged side by side along the edge of the ship outer plate 6, which is beneficial to the grouped use of the outer edge of the ship, so that the cables 5 can be laid without winding, interference, and the outer skin of the cable 5 can be prevented from being damaged by friction with the ship edge, and the damage of the paint of the outer plate 6 is also avoided.

[0062] S3, fix the support rod 3 on the body, and pull the cable 5 through the pulley 2 on the device.

[0063] After the body is fixed and hung, the lower end of the upper rod 33 and the upper end of the lower rod 34 are fixed by screw connection to complete the assembly of the support rod 3. The support rod 3 is inserted into the blind hole 141 on the vertical long plate 14 of the body, and the pin hole one and the pin hole two 341 are aligned and locked by inserting the pin to fix, so that the support rod 3 is vertically fixed on the body, and the assembly between the body and the support rod 3 is completed. As shown in Figure 8 The end of the cable 5 to be pulled is placed in the groove of the pulley 2 for pulling, which can realize labor-saving manual pulling. The pulley 2 rotates with the dragging of the cable 5, so that the friction is reduced, and the pulling process is more relaxed. At the same time, the cable 5 and the outer plate 6 are kept at a certain distance through the pulley 2, which avoids the damage of the cable 5 outer skin at the right angle of the outer plate 6 during the pulling process, and also avoids the damage of the paint of the outer plate 6 when the cable 5 directly rubs against the outer plate 6 under the influence of wind. Whether the support rod 3 needs to be removed can be determined according to the actual situation during manual pulling.

[0064] S4, as Figure 9 shown, after the cable 5 is pulled, the cable 5 is fixed and lifted through the support rod 3.

[0065] S4-1, the end of the cable 5 on the ship is wound and fixed on the pair of L-shaped hooks 32 on the same support rod 3, and the preliminary fixing of the cable 5 is realized by winding between the L-shaped hooks 32 oppositely arranged in the middle of the support rod 3, so as to prevent the cable 5 from falling.

[0066] S4-2, then, the preliminarily fixed cable 5 is lifted through the U-shaped fork 31 at the top of the support rod 3, so that the lifted cable 5 is higher than the working area of the construction personnel, and the lifted cable 5 is fixed through the high support point 8 on the ship near the cable 5. The cable 5 is arranged above the head of the construction personnel, and due to the limited width of the channel, the cable 5 will not have too much falling, so that an unobstructed deck 7 channel can be left for the smooth passage of the construction personnel, thereby improving the safety of the construction personnel during construction. The support point includes but is not limited to a bracket, a support frame or other existing fixed objects on the ship. Since the fixed objects are not involved in the patent, they will not be described here. In another embodiment, when there is no high support point 8 on the ship near the cable 5, the same device is installed on the corresponding edge protrusion of the ship body outer plate 6 on the opposite side of the current device through steps S2 and S3, the cable 5 is passed through the U-shaped fork 31 at the top end of the support rod 3 arranged on the opposite side and wound and fixed on the L-shaped hook 32 of the support rod 3, so as to ensure that the cable 5 does not bend when passing through the oppositely arranged U-shaped fork 31 at the top end of the support rod 3.

[0067] At this time, the device can be more firmly attached to the top of the outer edge of the outer plate 6 under the combined action of the gravity of the cable 5 and the clamping force at the bolt fastener 4; at the same time, since the cable 5 is also in the groove of the pulley 2, even if the cable 5 is blown by the wind, it will have a certain extension outside, thereby avoiding the friction between the cable 5 and the outer plate 6; according to the rise and fall of the tide, the other end of the cable 5 is fixed to the fixed point in the wharf area, so that the cable 5 is taut, which can further avoid the friction between the cable 5 and the outer plate 6. When the weight of the cable 5 is large, additional binding operation is performed on the cable 5. Specifically, after the cable 5 is preliminarily fixed by the support rod 3 and it is ensured that no displacement occurs, the cable 5 between the pulley 2 and the support rod 3 is fixed and bound to the nearest ship side rail, so that the cable 5 weight borne by the support rod 3 is dispersed through the structure of the ship body itself.

[0068] S5, after the cable 5 is used up, the cable 5 is restored and lowered and the device is removed.

[0069] S5-1, the cable 5 wound on the L-shaped hook 32 is unwound, and the cable 5 is lowered while keeping the cable 5 taut and the cable 5 still in the groove of the pulley 2. At this time, the cable 5 is slowly lowered by using the self-weight of the cable 5 and artificially controlling the lowering speed until the cable 5 is restored to the state before laying. This method avoids the friction between the outer skin of the cable 5 and the fast port of the outer edge of the ship body, effectively protecting the cable 5 and the paint of the outer plate 6.

[0070] S5-2, after all the cables 5 are safely lowered away from the ship, the positioning pin on the support rod 3 is removed, the support rod 3 is removed from the body, then the support rod 3 is split into the upper rod 33 and the lower rod 34; after the bolt fastener 4 used for fixing the body and the outer plate 6 is loosened, the body is removed from the outer plate 6 of the ship body.

[0071] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any person skilled in the art can make various changes or equivalent replacements to the features and embodiments without departing from the spirit and scope of the present application. In addition, the features and embodiments can be modified to adapt to specific conditions and materials under the guidance of the present application without departing from the spirit and scope of the present application. Therefore, the present application is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are within the scope of the present application.
