[0046] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0047] Please refer to the attached Figures 1 to 6 , a submarine cable construction pulling device 100 according to an embodiment of the present invention is described in detail.

[0048] The submarine cable construction pulling device 100 of the embodiment of the present invention comprises a base 1 and a first guide ring 2, an extrusion assembly 3, a second guide ring 4, a cable arrangement assembly 5 and a winding assembly 6 installed on the base 1. The first guide ring 2, the extrusion assembly 3, the second guide ring 4, the cable arrangement assembly 5 and the winding assembly 6 are arranged along a first direction (for example, Figure 1The extrusion assembly 3 includes a first elastic extrusion member 31 and a second elastic extrusion member 32. A threading gap 30 is provided between the first elastic extrusion member 31 and the second elastic extrusion member 32. The cable passes through the first guide ring 2, the threading gap 30, the second guide ring 4 and the cable arrangement assembly 5 in sequence and is then wound on the winding assembly 6. The first elastic extrusion member 31 and the second elastic extrusion member 32 are used to abut the cable.

[0049] When in use, the submarine cable construction pulling device 100 of the embodiment of the present invention pulls the steel cable (cable) tied to the submarine cable, and the steel cable passes through the first guide ring 2, the threading gap 30 of the extrusion assembly 3, the second guide ring 4, the cable arrangement assembly 5 in sequence, and is then wound around the winding assembly 6. The first guide ring 2, the extrusion assembly 3 and the second guide ring 4 guide and limit the steel cable. On the one hand, it ensures that the steel cable passes through the threading gap 30 of the extrusion assembly 3 smoothly, and ensures that the first elastic extrusion piece 31 and the second elastic extrusion piece 32 of the extrusion assembly 3 abut against the steel cable, which can not only squeeze the seawater on the steel cable, remove part of the seawater on the steel cable, and reduce the influence of seawater on the winding of the steel cable, which is beneficial to improve the service life of the steel cable, but also prepare a certain length of steel cable before entering the cable arrangement assembly 5, restrain and guide the steel cable in advance, and remove the influence of part of the submarine cable and seawater on the steel cable; on the other hand, it ensures that the steel cable enters the cable arrangement assembly 5 at the correct angle, avoids the unguided steel cable directly entering the cable arrangement assembly 5, causing the cable arrangement assembly 5 to bear the pulling force formed by the submarine cable during the cable arrangement, so that in the process of the winding assembly 6 winding the steel cable, the cable arrangement assembly 5 is ensured to arrange the steel cable normally, avoids the accumulation of the steel cable, knotting, dislocation, etc. during the winding process, and avoids the scattered winding of the steel cable, which affects the secondary use.

[0050] Therefore, the submarine cable construction pulling device 100 of the embodiment of the present invention can avoid uneven distribution of steel cables, avoid knotting and dispersion of steel cables that affect secondary use, and is beneficial to improving the construction efficiency when the steel cables are used again and to improving the service life of the steel cables.

[0051] In order to make the solution of the present application easier to understand, the first direction is the same as the left-right direction, and the second direction is the same as the front-back direction. Figures 1 to 6 As shown, the front-to-back direction is as shown in 1 to Figure 6 As shown, the up and down directions are as follows: Figure 6 shown.

[0052] The submarine cable construction pulling device 100 of the embodiment of the present invention comprises a base 1 and a first guide ring 2, an extrusion assembly 3, a second guide ring 4, a cable arrangement assembly 5 and a winding assembly 6 installed on the base 1. The first guide ring 2, the extrusion assembly 3, the second guide ring 4, the cable arrangement assembly 5 and the winding assembly 6 are arranged in sequence along the first direction. The cable passes through the first guide ring 2, the threading gap 30, the second guide ring 4 and the cable arrangement assembly 5 in sequence and is wound on the winding assembly 6.

[0053] like Figure 1 As shown, the first guide ring 2 and the second guide ring 4 are opposite to the middle part of the winding assembly 6 (which is also the middle part of the cable arrangement assembly 5).

[0054] The extrusion assembly 3 includes a first elastic extrusion member 31 and a second elastic extrusion member 32, and a threading gap 30 is provided between the first elastic extrusion member 31 and the second elastic extrusion member 32. The first elastic extrusion member 31 and the second elastic extrusion member 32 are used to abut against cables (wire cables). The first elastic extrusion member 31 and the second elastic extrusion member 32 both include a telescopic member 311, a mounting box 312 and a first elastic member 313. The telescopic member 311 extends along the second direction, which is perpendicular to the first direction. The telescopic member 311 has a telescopic end and a fixed end, and the fixed end is located on the side of the telescopic member 311 away from the threading gap 30. The side of the mounting box 312 facing away from the threading gap 30 is connected to the telescopic end, and the mounting box 312 is open toward one side of the threading gap 30. The first elastic member 313 is arranged on the mounting box 312, and a part of the first elastic member 313 is located outside the mounting box 312, and the first elastic member 313 of the first elastic extrusion member 31 and the first elastic member 313 of the second elastic extrusion member 32 define the threading gap 30 on the opposite side.

[0055] The telescopic member 311 has a telescopic function. When the telescopic member 311 of the first elastic extrusion member 31 and the second elastic extrusion member 32 is extended, the telescopic end drives the installation box 312 to move, the two first elastic members 313 are close to each other, and the threading gap 30 becomes smaller. When the telescopic member 311 is shortened, the two first elastic members 313 are far away from each other, and the threading gap 30 becomes larger. The submarine cable construction pulling device 100 of the embodiment of the present invention adjusts the position of the first elastic member 313 through the telescopic member 311, so that the size of the threading gap 30 can be ensured by adjusting the position of the first elastic member 313 after the first elastic member 313 is worn, and the abutment degree between the first elastic member 313 and the steel cable can be adjusted, and then the squeezing degree of the two first elastic members 313 on the steel cable is adjusted according to the actual application requirements, so as to adjust the water filtering and clamping effect on the steel cable. Therefore, the operation convenience and adaptability of the submarine cable construction pulling device 100 of the embodiment of the present invention are improved.

[0056] Specifically, the telescopic member 311 adopts a telescopic electric cylinder.

[0057] In some embodiments, the first elastic extrusion member 31 and the second elastic extrusion member 32 further include a first motor 314 and a driven shaft, the first motor 314 is arranged on the installation box 312, the output shaft of the first motor 314 extends into the installation box 312, the driven shaft is arranged in the installation box 312, and the output shaft and the driven shaft of the first motor 314 are opposite in the first direction. The first elastic member 313 includes a chain belt 3131 and elastic teeth 3132, the chain belt 3131 is sleeved on the output shaft and the driven shaft of the first motor 314, and a plurality of elastic teeth 3132 arranged at equal intervals are arranged on the outer surface of the chain belt 3131. At least a portion of the elastic teeth 3132 of the first elastic member 313 is located outside the installation box 312, and a threading gap 30 is formed between the elastic teeth 3132 on the adjacent side of the chain belts 3131 of the two first elastic members 313. When the steel cable passes through the threading gap 30, the multiple elastic teeth 3132 located outside the installation box 312 abut against the steel cable and clamp the steel cable.

[0058] After the first motor 314 is turned on, the output shaft of the first motor 314 rotates in a set direction, thereby driving the chain belt 3131 to rotate. For the first elastic extrusion member 31 located on the front side, the chain belt 3131 rotates counterclockwise, and for the second elastic extrusion member 32 located on the rear side, the chain belt 3131 rotates clockwise, so that the elastic teeth 3132 located outside the installation box 312 squeeze and drive the steel cable to move from left to right, thereby realizing the traction of the steel cable, pulling the underwater steel cable toward the base 1, and then assisting the winding assembly 6 to lift and pull the steel cable.

[0059] As a result, the first elastic extrusion member 31 and the second elastic extrusion member 32 achieve clamping and traction of the steel cable, increase the traction point and traction area of ​​the submarine cable construction pulling device 100 of the embodiment of the present invention on the steel cable, and advance the traction force point of the steel cable, that is, start pulling the steel cable before the winding assembly 6, thereby reducing the pulling and sagging effects of the steel cable on the cable arrangement assembly 5 due to its own gravity and the resistance formed by seawater, avoiding abnormal movement of the guide block 54 and the threaded block 53 of the cable arrangement assembly 5, and then avoiding the problems of docking and knotting of the steel cable when winding, thereby ensuring that the steel cable is evenly distributed in the length direction of the winding shaft 63 (that is, the second direction).

[0060] In some embodiments, the elastic teeth 3132 are made of rubber material, and the elastic teeth 3132 have a certain elasticity. When abutting and squeezing the steel cable, the elastic teeth 3132 avoid hard contact with the steel cable and avoid damaging the steel cable. The elastic teeth 3132 have an arc-shaped end surface on the side away from the chain belt 3131. The arc-shaped end surface is a smooth end surface. On the one hand, it can ensure the contact area with the steel cable during the movement and rotation of the chain belt 3131, thereby ensuring the traction effect of the squeezing component 3 on the steel cable. On the other hand, it can avoid the formation of sharp corners and mutual wear with the steel cable.

[0061] In some embodiments, the first elastic extrusion member 31 and the second elastic extrusion member 32 further include a fixed plate 315, a limiting rod 316 and a second elastic member 317. The fixed plate 315 is opposite to the telescopic member 311 in the first direction. The limiting rod 316 is slidably arranged on the fixed plate 315. One end of the limiting rod 316 is connected to the installation box 312. The second elastic member 317 connects the other end of the limiting rod 316 and the fixed plate 315. The fixed plate 315, the limiting rod 316 and the second elastic member 317 form an adjusting member that cooperates with the telescopic member 311. When the telescopic member 311 is extended and retracted to adjust the position of the installation box 312, the position of the limiting rod 316 changes accordingly driven by the installation box 312, and the degree of squeezing of the second elastic member 317 by the fixed plate 315 and the limiting rod 316 changes synchronously, so that while adapting to the position change of the installation box 312, the force of the telescopic member 311 is applied to the installation box 312 through the second elastic member 317, ensuring that the installation box 312 with a certain length in the first direction can remain stable and avoid deflection, thereby ensuring that the first elastic member 313 on the installation box 312 clamps the steel cable, and ensuring the traction effect of the extrusion assembly 3 on the steel cable, thereby improving the stability and reliability of the submarine cable construction pulling device 100 of the embodiment of the present invention.

[0062] Specifically, the adjusting members (ie, the fixing plate 315 , the limiting rod 316 and the second elastic member 317 ) are symmetrically provided on the left and right sides of the telescopic member 311 .

[0063] In some embodiments, the winding assembly 6 includes a support frame 61, a second motor 62, a winding shaft 63, a bottom bin 64 and a cover plate 65. The second motor 62 is arranged on the support frame 61, and the winding shaft 63 is rotatably arranged on the support frame 61. The output shaft of the second motor 62 is connected to the winding shaft 63, and the winding shaft 63 extends along the second direction. The bottom bin 64 is located on the side of the winding shaft 63 adjacent to the base, and a drainage hole 641 is provided on the bottom bin 64. The cover plate 65 is hingedly arranged on the bottom bin 64, and the cover plate 65 and the bottom bin 64 surround the winding shaft 63. The cover plate 65 and the bottom bin 64 are provided with a connecting port 642 on the side (left side) facing the cable arrangement assembly 5.

[0064] The cover plate 65 and the bottom bin 64 form a protective shell around the winding shaft 63, which can protect the steel cable on the winding shaft 63. The connecting port 642 provided between the cover plate 65 and the bottom bin 64 facilitates the steel cable to pass through the protective shell and be wound on the winding shaft 63. When winding the steel cable, the second motor 62 is turned on, and the second motor 62 drives the winding shaft 63 to operate, and the steel cable passes through the connecting port 642 and is wound on the winding shaft 63, and the seawater dripped from the steel cable is discharged from the drainage hole 641.

[0065] Specifically, the lower end of the bottom bin 64 is provided with a plurality of support legs 66, and the support legs 66 are provided on the base 1. The right side of the bottom bin 64 and the right side of the cover 65 are hinged by hinges 68, and the left side of the bottom bin 64 and the left side of the cover 65 are provided with locks 67, which can fix the bottom bin 64 and the cover 65. After the locks are opened, the cover 65 can be opened to facilitate observation of the internal steel cable or maintenance and cleaning.

[0066] In some embodiments, the cable arrangement assembly 5 includes a mounting seat 51, a reciprocating screw 52, ​​a threaded block 53 and a guide block 54. The mounting seat 51 is arranged on the bottom bin 64, the reciprocating screw 52 is rotatably arranged on the mounting seat 51, the reciprocating screw 52 is connected to the output shaft of the second motor 62, the threaded block 53 is sleeved on the reciprocating screw 52, ​​the guide block 54 is arranged on the threaded block 53, and a threading hole 541 is provided on the guide block 54, and the threading hole 541 is opposite to the connecting port 642 in the first direction. The threading hole 541 is used for the steel cable to pass through. When the second motor 62 is turned on, the second motor 62 drives the winding shaft 63 to rotate while driving the reciprocating screw 52 to rotate unidirectionally, thereby driving the threaded block 53 to move back and forth on the reciprocating screw 52, ​​and then driving the guide block 54 to move back and forth, so as to realize the forward and backward movement of the steel cable, and then realize the cable arrangement of the steel cable, and ensure that the steel cable is evenly arranged on the winding shaft 63.

[0067] like Figure 1 As shown, the reciprocating screw 52 has two thread grooves with the same pitch and opposite rotation directions. After the second motor 62 is turned on, as the reciprocating screw 52 rotates, the thread block 53 first moves backward, and then moves forward after moving to abut against the mounting seat 51 at the rear end of the reciprocating screw 52, ​​and then moves backward after moving forward to abut against the mounting seat 51 at the front end of the reciprocating screw 52, ​​and so on. The reciprocating screw 52 and the thread block 53 are mature technologies in the prior art and will not be described in detail here.

[0068] Specifically, a first pulley is provided at one end of the reel 63 away from the second motor 62, a second pulley is provided at one end of the reciprocating screw 52, ​​and the submarine cable construction pulling device 100 further includes a transmission belt 7, which connects the first pulley and the second pulley. The second motor 62 is connected to the reciprocating screw 52 through the first pulley, the second pulley and the transmission belt 7, with a simple structure and stable motion transmission.

[0069] The cable arrangement assembly 5 further includes a mounting plate 55, on which a mounting seat 51 is arranged, and a notch 551 is provided on the mounting plate 55, the notch 551 extending along the second direction, the notch 551 and the connecting port being opposite in the first direction, and the guide block 54 being slidably arranged in the notch 551. The notch 551 of the mounting plate 55 can limit and guide the movement of the guide block 54, thereby ensuring the correctness and stability of the reciprocating movement of the guide block 54, thereby further ensuring the uniform arrangement of the steel cable on the reel 63.

[0070] Specifically, the right side of the second guide ring 4 and the left side of the threading hole 541 are both provided with chamfers to form an expanded hole, and the chamfers are preferably arc-shaped chamfers, thereby providing a certain space for the deflection of the steel cable during the reciprocating movement of the guide block 54, thereby avoiding wear between the steel cable and the right-angle edges on the second guide ring 4 and the guide block 54.
