[0002] The laying of ship cables is an important part of the shipbuilding process and an important factor affecting the construction progress and efficiency. It requires the reasonable use of the narrow space on board, the optimization of the direction, the avoidance of cross-confusion, and the realization of power and signal transmission between numerous devices. However, it is inevitable to encounter turns and bulkhead penetrations, which adds difficulties to the laying of ship cables.

[0003] In addition, as ships gradually develop towards larger sizes, the workload of laying cables on ships is also increasing.

[0027] The present invention is further described below in conjunction with the accompanying drawings.

[0028] according to Figure 1 The present invention discloses a fully automatic ship cable laying device, which is an automatic conveying device on a cable bracket. The overall device adopts a split structure, which is convenient for installation, disassembly and movement.

[0029] The cable bracket includes a first straight laying section and a second straight laying section which are a straight laying section and a turning laying section; the straight laying section includes vertical supports on both sides and a support arm connecting the vertical supports on both sides; the turning laying section includes vertical supports with curvature on both sides and a flat bar connecting the vertical supports on both sides; the flat bar is an integrated structure consisting of two vertical flat bars perpendicular to the vertical supports and a horizontal bar.

[0030] The cable linear conveyor provides the main power for the cable conveying process, and the cable traction machine provides the auxiliary power for the cable conveying process. Both are equipped with force sensors for detecting whether the conveying force during the cable conveying process is normal.

[0031] The speed matcher controls the speed of the cable linear conveyor and the cable traction machine to match the conveying speed and the dragging speed of the two.

[0032] The smoothing device is installed at the initial end, middle part and end of the straight laying section to reduce the friction between the cable and the cable bracket during the transmission process and make the cable laying smooth. The cable bender is installed at the turning laying section to achieve smooth laying and transition of the cable at the turning. The radius of the cable turning can be changed according to actual conditions through the smoothing device and the cable bender.

[0033] The device is also equipped with an alarm and emergency stop module, which determines whether the cable laying process is normal based on the conveying force information detected by the force sensor. When an abnormality occurs in the cable laying process, the cable linear conveyor and cable traction machine are automatically shut down through the alarm and emergency stop module.

[0034] like Figures 1 to 4As shown, the smoothing device includes a clamping plate 1, a screw 2, a transverse profile 3, a rotating shaft 6, a slider 7 for installing a vertical roller, a vertical roller 5 and a horizontal roller 4. A groove slightly wider than the width of the vertical bracket of the cable bracket is provided on the inner side of the clamping plate 1. The clamping plate 1 is clamped on the vertical bracket of the cable bracket through the groove. Threaded holes are provided on the outer sides of the clamping plates 1 on both sides. The screw 2 is controlled to rotate in the threaded holes to adjust the tightness between the clamping plate 1 and the cable bracket. A circular hole is provided at the lower end of the clamping plate 1, which is fixed to the transverse profile 3 by a right angle bracket. The transverse profile 3 is installed on the bracket arm of the cable bracket. The slider 7 for installing the vertical roller is installed in the slide groove of the transverse profile 3 and can move in the slide groove. The position of the slider is adjusted according to different cable turning radius. The upper end of the slider 7 for installing the vertical roller is fixed to the rotating shaft 5 by threads. A bearing is embedded inside the vertical roller 5. The vertical roller 5 is rotatably connected to the rotating shaft 5 through the bearing, so that the vertical roller 5 can rotate freely on the slider 7. The horizontal roller 4 is close to the transverse profile 3 and is installed on the bracket arm.

[0035] like Figure 1 , Figures 5 to 7 As shown, the cable bender is to be fixed on the flat bar of the turning laying section, including a transverse profile 3, an inner clamping plate 8 close to the turning radius, an outer clamping plate 9 close to the turning radius, a vertical roller 5, a rotating shaft 6, a slider 7 and a horizontal roller 4; the inner clamping plate 8 is installed on the inner side of the transverse profile 3 close to the turning radius, and the outer clamping plate 9 is installed close to the outer side of the turning radius. The shapes of the clamping plates on both sides are different and the outer clamping plate 9 is longer than the inner clamping plate 8; the two ends of the inner clamping plate 8 are clamped on the vertical flat bar and are tightened with bolts after clamping; Both ends of the side clamps 9 are clamped on the vertical flat bar and tightened with bolts after clamping; round holes are provided at the lower ends of the clamps on both sides, and are fixed to the horizontal profile 3 by right-angle brackets; vertical rollers 5 are installed on the inner sides of the clamps on both sides, and the vertical rollers 5 are rotatably connected to the rotating shaft 6 through the bearings embedded inside, and the vertical rollers 5 are connected to the slider 7 through the rotating shaft 6, and the slider 7 is installed in the slide groove of the horizontal profile 3, so that the vertical roller 5 rotates on the slider 7 and moves on the horizontal profile 3; the horizontal roller 4 is close to the horizontal profile 3 and is installed on the horizontal flat bar.

[0036] According to different turning radius requirements, the position of the slider 7 on the transverse profile of the straight and turning laying sections is adjusted to indirectly drive the vertical roller 5 to move. When the cable in the conveying process passes through the position change of the vertical roller 5, the turning radius of the cable is changed, thereby assisting the cable to complete the turning task.

[0037] The length of the transverse profile 3 of this embodiment reserves a large amount of length margin, which is convenient for use on cable trays of different specifications and widths. The cable is transported under the operation of the cable linear conveyor and the cable traction machine. A smoothing device is provided at the initial and end positions of the cable tray, which can reduce the friction between the cable and the cable tray and improve the durability of the cable. When the cable passes through the cable turning point, the cable bender for the straight and turning laying sections is installed in advance according to the preset turning radius, and the slider 7 on the transverse profile 3 is moved to the corresponding position. When the cable contacts the vertical roller 5 on the slider 7, it is simultaneously subjected to the conveying force along the conveying direction and the extrusion force pointing inward to the turning radius, so that the cable passes through the cable turning point smoothly. After leaving the turning point, it is only subjected to the conveying force from the two machines. When the cable end passes through the end section of the cable tray, the cable laying work of the entire section has been completed.

[0038] During operation, if the cable encounters scratches, the force sensors in the cable linear conveyor and cable traction machine will receive abnormal force signals and immediately stop both machines. The speed matcher equipped in the whole device can control the working speed of the two machines to prevent the cable from slightly bending due to speed difference.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
