[0002] Cable splicing is an important technical measure in dam construction, which helps to ensure the continuity, safety and economy of construction. During the construction process, the cable may be damaged or fail due to various factors (such as environmental impact, mechanical damage, etc.), resulting in power and communication interruptions. In order to repair the fault and restore function as soon as possible, the cable needs to be spliced.

[0003] The cable connection method usually includes steps such as stripping, twisting and using connectors to ensure good electrical contact and insulation protection. The general cable connection requires manual stripping of the internal wires, and then arranging the copper wires inside the cable to loosen the copper wires inside the cable, and then manually connecting the two sections of the cable. The cable connection steps are cumbersome, and manual operation is time-consuming and labor-intensive, which cannot meet actual needs. Summary of the invention

[0018] A method for connecting a cable connecting device for dam construction, comprising the following steps:

[0019] S1. Conveying: Pass the two ends of the cable to be connected through the fixed wheel and the conveying roller respectively, and use the friction force to convey the cable forward by rotating the conveying handle and the conveying roller;

[0020] S2, cable sheath cutting: the cable is transmitted forward through the support of the support plate, and the movable knife is lowered by turning the sheath cutting handle, and the movable knife is lowered to a position where the cable sheath can be cut, and the cable sheath is cut by the movable knife and the fixed knife;

[0021] S3, Separate the copper wires: Use the separation handle to rotate the separation frame so that the rotating clamp and the fixed clamp clamp the copper wires in the cable, separate the twisted copper wires by rotation, and continue to convey the cable so that the copper wires on the cable are located above the block. Since each copper wire is separated, the copper wires at both ends of the cable cross each other and are connected together;

[0022] S4. Torsion connection: By rotating the extrusion handle, the two-way threaded rod drives the two transmission blocks to move toward each other, driving the extrusion bar and the pressure block, so that the pressure block descends to squeeze the copper wire between the two blocks, so that the copper wires crossing each other at both ends of the cable are tightly combined, and by rotating the connecting frame, the copper wires crossing each other at both ends of the cable are twisted, and the two ends of the cable are connected to each other.

[0023] From the above, it can be seen that the cable splicing equipment and splicing method for dam construction provided by the present invention have the following technical effects.

[0024] First, the copper wires at both ends of the cable are crossed and connected together. By rotating the extrusion handle, the two-way threaded rod drives the two transmission blocks to move toward each other, driving the extrusion bar and the pressure block, so that the pressure block descends to squeeze the copper wires between the two blocks. By rotating the connecting frame, the copper wires that cross each other at both ends of the cable are twisted. The two ends of the cable are connected together. Through the extrusion and twisting of the pressure block and the block, the copper wires of the two crossed cable sections are twisted together, which simplifies the steps of connecting cables and improves the efficiency of connecting cables.

[0025] Second, the separation frame is rotated by the separation handle so that the rotating clamp and the fixed clamp clamp the copper wire in the cable. The rotation of the separation frame drives the connecting bar to make the rotating clamp and the fixed clamp rotate relative to each other, so that the fixed clamp drives the sliding bar to slide inside the fixed rail to compress the spring, thereby further clamping the copper wire in the cable. The twisted copper wires are separated by rotation. The direction of rotation is opposite to the twisting direction of the copper wires in the cable, so that the copper wires are spread out from each other and gaps are generated between the copper wires, thereby achieving the effect of separating the copper wires in the cable.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] The cable splicing device and the splicing method for dam construction disclosed by the present invention are mainly used in general cable splicing, which requires manual stripping of the internal conductors, and then arranging the copper wires inside the cable to loosen the copper wires inside the cable, and then manually connecting the two sections of the cable. The cable splicing steps are cumbersome and the manual operation is time-consuming and laborious.

[0039] Separation mechanisms are installed on the upper surface of the bottom plate 1 near the two sides of the connecting frame 6, and the separation mechanisms are used to separate the copper wires in the cable from each other;

[0040] A skin cutting mechanism is installed on one side of the upper surface of the bottom plate 1 close to the separation mechanism, and the skin cutting mechanism is used to cut the skin of the cable;

[0041] A feeding mechanism is installed on one side of the upper surface of the bottom plate 1 close to the skin cutting mechanism, and the feeding mechanism is used to convey the cable forward.

[0042] The slide rod 43 slides inside the slide groove 38, and the threads at both ends of the bidirectional threaded rod 35 rotate in opposite directions. The bidirectional threaded rod 35 can simultaneously drive the transmission blocks 36 at both ends to move toward each other or in opposite directions.

[0043] In this embodiment, the cable is continuously conveyed so that the copper wire is located between the two blocks 42. Another cable is inserted from the other end of the device according to the same operation, and the cable is stripped and dispersed so that the copper wires of the two cables are located between the two blocks 42. At this time, the copper wires need to be manually arranged and preliminarily connected. By rotating the squeezing handle 34, the two-way threaded rod 35 drives the two transmission blocks 36 to move toward each other, driving the squeezing bar 41 and the pressing block 40, so that the pressing block 40 descends and squeezes the copper wire between the two blocks 42, so that the copper wires that cross each other at both ends of the cable are tightly combined. By rotating the connecting frame 6, the copper wires that cross each other at both ends of the cable are twisted, and the two ends of the cable are connected to each other. Through the squeezing and twisting of the pressing block 40 and the block 42, the copper wires of the two cross-linked cable sections are twisted together, which simplifies the steps of connecting cables and improves the efficiency of connecting cables.

[0044] Furthermore, after the connection is completed, the release bar 31 and the installation bar 33 are separated by removing the bolt 32 on one side of the notch 44 , and the cable is taken out from between the release bar 31 and the installation bar 33 .

[0045] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 and Fig. 9 In a preferred embodiment, the separation mechanism includes two separation slide rails 8 fixedly connected to the upper surface of the base plate 1, the separation slide rails 8 are internally slidably connected with a slider 22, the upper surface of the slider 22 is rotatably connected with a fixed rail 21, the fixed rail 21 is internally slidably connected with a slide bar 23, a spring 27 is arranged inside the fixed rail 21, the upper surface of the slide bar 23 is fixedly connected with a fixing clip 30, and the upper surface of the fixing clip 30 is arranged with a plurality of second separation sheets 29.

[0046] One side of the fixed clamp 30 is rotatably connected to a rotating clamp 24, and a plurality of first separation sheets 28 are provided on one side surface of the rotating clamp 24. The top of the rotating clamp 24 is rotatably connected to a connecting strip 25, and the bottom of the connecting strip 25 is rotatably connected to a separation frame 5. The top of the separation frame 5 is fixedly connected to a separation handle 26.

[0047] One side of the bottom of the separation frame 5 is slidably connected to one side of the fixed rail 21. Since the fixed rail 21 is arc-shaped, the sliding track of the slide bar 23 inside the fixed rail 21 is an arc-shaped. Similarly, when the separation frame 5 slides on one side of the fixed rail 21, the track is also an arc-shaped.

[0048] In this embodiment, the cable is continuously conveyed forward so that the exposed copper wire of the cable extends between the rotating clamp 24 and the fixed clamp 30, and the separation frame 5 is rotated by the separation handle 26 so that the rotating clamp 24 and the fixed clamp 30 clamp the copper wire in the cable. The rotation of the separation frame 5 drives the connecting strip 25 so that the rotating clamp 24 and the fixed clamp 30 rotate relative to each other, and the first separation sheet 28 and the second separation sheet 29 can be inserted into the gap between the copper wires of the cable. The separation frame 5 is continuously rotated so that the fixed clamp 30 drives the slide bar 23 to slide inside the fixed rail 21 to compress the spring 27, thereby further clamping the copper wire in the cable, and the twisted copper wires are separated by rotation. The direction of rotation is opposite to the direction of twisting of the copper wires in the cable, so that the copper wires are dispersed from each other, and gaps are generated between the copper wires, thereby achieving the effect of separating the copper wires in the cable.

[0049] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the skin cutting mechanism includes two mounting plates 4 fixedly connected to the upper surface of the base plate 1 near the separation mechanism, the upper surface of the mounting plate 4 is fixedly connected with a mounting disk 17, the top of the mounting disk 17 is threadedly connected with a skin cutting threaded rod 16, the top of the skin cutting threaded rod 16 is fixedly connected with a skin cutting handle 15, the bottom end of the skin cutting threaded rod 16 is rotatably connected with a movable knife 18, and the upper surface of the movable knife 18 is fixedly connected with a guide rod 14.

[0050] The upper surface of the bottom plate 1 is fixedly connected with a fixed block 20 at the bottom position of the movable knife 18 , and the upper surface of the fixed block 20 is fixedly connected with a fixed knife 19 . The guide rod 14 is slidably connected between the mounting plates 17 , and the guide rod 14 penetrates the mounting plates 17 .

[0051] In this embodiment, the movable knife 18 is lowered by rotating the skin cutting handle 15, and the guide rod 14 and the mounting plate 17 slide relative to each other. The movable knife 18 is lowered to a position where it can cut the cable sheath. One end of the cable contacts the movable knife 18 and the fixed knife 19. By continuing to convey the cable forward, the movable knife 18 and the fixed knife 19 cut the cable sheath. The cutting of the movable knife 18 and the fixed knife 19 exposes the copper wire inside the cable, thereby achieving the effect of removing the cable sheath during the process of conveying the cable.

[0052] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the feeding mechanism includes two fixed columns 2 fixedly connected to the upper surface of the base plate 1 near the mounting plate 4, the top of the fixed column 2 is fixedly connected to the support plate 3, the upper surfaces of the two ends of the base plate 1 are respectively fixedly connected to two fixed plates 12, and the tops of the fixed plates 12 are respectively rotatably connected to fixed wheels 13.

[0053] A mounting column 9 is fixedly connected to the upper surface of the base plate 1 near the fixed wheel 13, a conveying roller 11 is rotatably connected to the top of the mounting column 9, a conveying handle 10 is fixedly connected to one end of the conveying roller 11, and a friction strip is provided on the outer surface of the conveying roller 11.

[0054] In this embodiment, a gap is formed between the fixed wheel 13 and the conveying roller 11 by respectively passing the two ends of the cable to be connected through the fixed wheel 13 and the conveying roller 11, so that the cable can be conveyed forward by rotating the conveying handle 10 and the conveying roller 11 using friction. The support plate 3 can be used to support the cable to prevent the cable from falling, so that the cable can continue to be conveyed forward with the support of the support plate 3. The friction strip on the conveying roller 11 can also increase the friction to prevent the cable from slipping during conveying, thereby achieving the effect of fixing and conveying the cable.

[0055] Working principle: When in use, the two ends of the cable to be connected are passed through the fixed wheel 13 and the conveying roller 11 respectively, and a gap is formed between the fixed wheel 13 and the conveying roller 11, so that the cable can be conveyed forward by rotating the conveying handle 10 and the conveying roller 11, and the friction force is used to convey the cable forward. The support plate 3 can be used to support the cable to prevent the cable from falling, so that the cable can continue to be conveyed forward with the support of the support plate 3. The friction strip on the conveying roller 11 can also increase the friction force to prevent the cable from slipping when conveying, thereby achieving the effect of fixing and conveying the cable. The position of the movable knife 18 is lowered by rotating the skin cutting handle 15, and the guide rod 14 and the mounting plate 17 slide relative to each other, and the movable knife 18 is lowered to a position where the outer skin of the cable can be cut. The movable knife 18 and the fixed knife 19 are used to cut the outer skin of the cable. The copper wire inside the cable is exposed by the cutting of the movable knife 18 and the fixed knife 19, which has the effect of removing the outer skin of the cable during the process of conveying the cable. The cable is continued to be conveyed forward, so that the exposed copper wire of the cable extends between the rotating clamp 24 and the fixed clamp 30. The separation frame 5 is rotated by the separation handle 26 to clamp the copper wire in the cable with the rotating clamp 24 and the fixed clamp 30. The rotation of the separation frame 5 drives the connecting strip 25 to rotate the rotating clamp 24 and the fixed clamp 30 relative to each other, and the first separation piece 28 and the second separation piece 29 can be inserted into the cable. The separation frame 5 is continued to rotate so that the fixing clamp 30 drives the slide bar 23 to slide inside the fixing rail 21 to compress the spring 27, further clamping the copper wires in the cable, and separating the twisted copper wires by rotation. The direction of rotation is opposite to the twisting direction of the copper wires in the cable, so that the copper wires are spread out from each other, and gaps are generated between the copper wires, which has the effect of separating the copper wires in the cable. The cable is continued to be transmitted so that the copper wires are located between the two blocks 42. The other cable is inserted from the other end of the device according to the same operation, and the skin is peeled and dispersed so that the copper wires of the two cables are located between the two blocks 42. At this time, the copper wires need to be manually arranged and preliminarily connected. By rotating the squeezing handle 34, the bidirectional screw The grooved rod 35 drives the two transmission blocks 36 to move toward each other, driving the extrusion bar 41 and the pressure block 40, so that the pressure block 40 descends and squeezes the copper wire between the two blocks 42, so that the copper wires that cross each other at both ends of the cable are tightly combined, and by rotating the connecting frame 6, the copper wires that cross each other at both ends of the cable are twisted, and the two ends of the cable are connected to each other. Through the extrusion and twisting of the pressure block 40 and the block 42, the copper wires of the two intersecting sections of the cable are twisted together, which simplifies the steps of connecting the cables and improves the efficiency of connecting the cables. After the connection is completed, the release bar 31 and the installation bar 33 are separated by removing the bolt 32 on one side of the notch 44, and the cable is taken out from between the release bar 31 and the installation bar 33.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
