[0002] As a complex system engineering, the electrical system of ship is an important part to ensure the normal operation of ship, and cable laying is a key link of ship electrical system installation, which directly affects the safety, reliability and maintenance convenience of ship. However, the cabin space of ship is narrow and complex, and cable laying operation faces many technical problems. For example, during the process of ship construction and maintenance, cable laying usually needs to be carried out in narrow cabin with dense equipment. The traditional method relies on manual measurement and positioning, which is complicated and inefficient. Due to the limitation of cabin space, it is difficult to plan the cable laying path, and the traditional laying tool is difficult to adapt to the complex space structure, which leads to unreasonable cable path and insufficient bending radius, and further may cause cable damage or signal transmission quality decline. In addition, manual operation in narrow space has safety hazards, and the operator is easily affected by space limitation and inconvenience of tool use.

[0003] In the prior art, ship cable laying mainly relies on general tools, and lacks special equipment. These tools have low positioning accuracy, and it is difficult to ensure the accuracy and consistency of cable laying path. At the same time, the adaptability of existing tools is poor, which cannot meet the changing needs of different cabin structures and cable specifications. The lack of operation flexibility further affects the operation efficiency. With the progress of shipbuilding technology, higher requirements are put forward for the precision, efficiency and safety of cable laying, and it is an urgent technical problem to develop a special device suitable for ship cable laying.

DETAILED DESCRIPTION

[0026] The utility model will be further described in detail below with reference to the drawings.

[0027] Reference Figures 1 to 5 A magnetic attraction guide device for ship cable laying, comprising a base 1, a magnetic attraction positioning module 2, a guide mechanism 6, an angle adjusting mechanism 17 and an auxiliary fixing mechanism 24. The specific implementation of each component is as follows:

[0028] The base 1 is a rectangular aluminum alloy frame with a length-width ratio of 2:1, and the corners are rounded to improve corrosion resistance. The base 1 is equipped with two pairs of foldable anti-skid feet 28 on the bottom edge, which are L-shaped stainless steel pieces connected to the base 1 through a foot pivot 29. The foot pivot 29 is equipped with a torsion spring 30 and a positioning pin 31. The anti-skid feet 28 form a 60° angle with the base 1 when unfolded, providing additional support on non-horizontal metal walls. The base 1 is equipped with two parallel sliding rails on the top, on which the auxiliary fixing mechanism 24 is installed.

[0029] The magnetic positioning module 2 is composed of a magnetic guide plate 4 and a permanent magnet array 3. The magnetic guide plate 4 is a rectangular low-carbon steel plate with a thickness of 1 / 3 of the height of the base 1, and the surface is processed with a radial anti-displacement convex pattern 5 with a height of 1-2mm. The permanent magnet array 3 is composed of 24 square neodymium iron boron magnet units arranged in a 4×6 matrix, embedded in the groove of the magnetic guide plate 4, and the distance between the magnet units is 1 / 5 of the groove width. The magnetic guide plate 4 is fixed to the bottom of the base 1 through four groups of stainless steel bolts, and the distance between the bolt holes and the edge of the base 1 is 1 / 10 of the length of the base 1.

[0030] The guide mechanism 6 includes a pair of guide wheel sets 7, which are symmetrically arranged with a driving guide wheel 8 and a driven guide wheel 9. The driving guide wheel 8 is a conical polyurethane wheel with a 30° taper angle and an equidistant triangular anti-slip tooth pattern 11 on the outer periphery to prevent cable slipping. The driven guide wheel 9 is a cylindrical rubber wheel with a 3mm thick rubber layer on the surface to provide cushioning and avoid damage to the cable surface. The two guide wheel axes form a 60° V-shaped angle, forming a V-shaped guide channel 10 with a width that can adapt to cables with a diameter of 10-50mm. The guide wheel set 7 is connected to the angle adjustment mechanism 17 through a universal connecting shaft 12, and the spherical hinge part 13 of the universal connecting shaft 12 is matched with the limiting sleeve 14, which has three annular positioning grooves 15 on the inner wall. The hemispherical limiting protrusion 16 of the spherical hinge part 13 is embedded in the groove, limiting the swinging angle of the guide wheel set 7 to ±45°.

[0031] The angle adjustment mechanism 17 includes a rotating lock disc 18, a positioning slot 19 and a manual operating handle 21. The rotating lock disc 18 is a circular brass disc with 24 cylindrical positioning slots 19 evenly distributed on the surface. The depth of the positioning slot 19 is 1 / 4 of the disc thickness. The central pivot 20 penetrates the base 1 and is connected to the base 1 through a tapered roller bearing. The manual operating handle 21 is a T-shaped stainless steel handle connected to the rotating lock disc 18 through a connecting rod mechanism 22. The connecting rod mechanism 22 has a built-in worm and gear assembly 23 (the connecting rod mechanism 22 drives the worm to rotate, and the rotation of the worm controls the lifting of the worm), and the pitch of the worm is twice the pitch of the worm gear, realizing self-locking function.

[0032] The auxiliary fixing mechanism 24 comprises a pair of extendable clamping arms 25, which are C-shaped aluminum alloy arms with arc-shaped anti-skid rubber pads 27 at the ends. The rubber pads 27 are processed with fishbone-shaped grooves on the surface to increase the friction. The clamping arms 25 slide through the slide rails on the top of the base 1, and the locking knobs 26 are butterfly-shaped stainless steel nuts, which can fix the clamping arms 25 at any position of the slide rails after being tightened. The maximum extension length is 1 / 2 of the width of the base 1.

[0033] The overall working process is as follows:

[0034] In use, the device is adsorbed on the metal wall of the cabin of the ship through the magnetic positioning module 2, and the anti-skid feet 28 are expanded according to the inclination angle of the wall to enhance the stability. The rotary locking disc 18 is manually rotated to the specified angle, and then the handle 21 is operated to drive the worm and gear assembly 23 to control the rotation of the worm wheel, which drives the worm to lift. The worm and the corresponding positioning slot 19 form a plug-in limit, the spatial angle of the guide wheel set 7 is adjusted through the universal connecting shaft 12, the V-shaped guide channel 10 is aligned with the preset cable path, the cable is inserted into the channel, the clamping arms 25 of the auxiliary fixing mechanism 24 clamp the end of the cable, and the locking knobs 26 fix the position. During the laying process, the anti-skid teeth 11 and the rubber pads 27 work together to prevent the cable from sliding, and the self-locking function of the angle adjusting mechanism 17 ensures the stability of the guide path. After the laying is completed, the anti-skid feet 28 are folded and the device is disassembled, and the next cable laying can be performed.

[0035] The specific embodiment is only an explanation of the utility model, and is not a limitation of the utility model. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.
