Description

Technical Field

[0001] The invention relates to the field of cable line maintenance, and in particular to a line obstacle clearing tool. Background Art

[0002] Cable is a device used to transmit electric energy, signals, etc., usually composed of conductors, insulation layers, sheaths, etc. Cables are widely used in the fields of electricity, communications, transportation, etc., providing power supply and signal transmission for various equipment and systems. The selection of cables varies depending on the use scenarios. When cables need to be laid outdoors, the cables need to resist wind interference, so their structural strength is high. When cables need to be laid on the ground, there is no need to consider wind interference, so their structural strength is weak.

[0003] The Chinese patent with the publication number "CN116845805A" discloses that "the cable deicing device includes a main body, a deicing assembly and a driving assembly; the main body is provided with a channel for the cable to pass through; the deicing assembly is connected to the main body, and the deicing assembly is used to remove ice or snow covering the outer periphery of the cable". Although it can remove ice or snow on the surface of the cable, thereby preventing the accumulation of more ice and snow on the surface of the cable and increasing the load-bearing capacity of the cable, avoiding damage to the cable, and ensuring the normal transmission of electricity, it cannot clamp and de-ice cables of any diameter.

[0017] The beneficial effects of the present invention are as follows:

[0018] By setting an adaptive clamping structure, starting motor 1 drives gear 2 at the rear to rotate, and then drives half-toothed ring 1 at the top to rotate, and rotates synchronously with half-toothed ring 1 at the bottom, so that the two half-toothed rings 1 rotate together, driving three gears 1 to rotate, and then driving three arc-shaped limit blocks to rotate. The three arc-shaped limit blocks rotate through three arc-shaped grooves respectively, driving the three threaded crushing wheels to drive the three telescopic blocks to contract, so that the distance between the three threaded crushing wheels becomes larger, and cables with larger diameters can be clamped through the three threaded crushing wheels. Therefore, by starting motor 1, the distance between the three threaded crushing wheels can be freely adjusted, and cables of any diameter can be clamped, thereby improving the use range of cable clearing tools and the versatility of clearing tools, so that they can adapt to the clearing needs of cables with different diameters, and can play a stable and efficient role in various complex clearing scenes.

[0019] By setting up a spiral forward structure, the three gears rotate synchronously, which can drive the three threaded crushing wheels to rotate synchronously. The spiral forward movement allows the threaded crushing wheels to continuously contact the ice layer on the cable surface at a certain angle and pressure, continuously cutting and crushing the ice layer. This continuous action mode can more effectively break the ice layer, and the ice breaking effect is more significant compared to single-direction impact or simple friction;

[0020] The spiral advance mode provides a relatively stable travel trajectory for the tool. Compared with linear advance or other irregular movement modes, it is less likely to deviate from the direction or shake, ensuring that the tool can always maintain a relatively stable position with the cable when breaking ice on the cable surface, thus improving the accuracy and efficiency of obstacle removal.

[0021] Through the cooperation of the universal joint and the telescopic rod, when the spacing between the three threaded crushing wheels changes, the three gears can still drive the three threaded crushing wheels to rotate synchronously, avoiding transmission failure and causing the tool to stop operating;

[0022] By setting up a support and restriction structure, the line clearing tool can only move horizontally along the cable, so that the four sliding legs can play a supporting role. The ground cable is often difficult to stably support the weight of the clearing tool alone due to its low structural strength. With these four sliding legs, the gravity of the clearing tool carried by the cable can be effectively shared. In this way, the situation where the ground cable cannot bear the weight of the clearing tool and the de-icing operation cannot be carried out effectively is avoided. At the same time, it also prevents the cable from being deformed and damaged due to pressure, protects the structural integrity of the cable, extends the service life of the cable, and provides reliable guarantee for the stability and safety of power transmission.

[0037] Start the motor 13 to drive the rear gear 2 12 to rotate, and then drive the half-toothed ring 10 near the top to rotate, and rotate synchronously with the half-toothed ring 10 near the bottom, so that the two half-toothed rings 10 rotate together, drive the three gears 11 to rotate, and then drive the three arc-shaped limit blocks 15 to rotate. The three arc-shaped limit blocks 15 rotate through the three arc-shaped grooves 36 respectively, drive the three telescopic blocks 14 to contract through the three threaded crushing wheels 16, so that the distance between the three threaded crushing wheels 16 becomes larger, and the cables with larger diameters can be clamped by the three threaded crushing wheels 16.

[0038] In this embodiment, the output shaft of the motor 13 passes through the interior of the through-slot 1 and is fixedly connected to the gear 2 12, and the gear 2 12 is meshedly connected to the outer ring of the half gear ring 10, and the front and rear parts of the outer surface of the upper shell 1 near the bottom of one side and the front and rear parts of the outer surface of the lower shell 2 near the top of one side are fixedly connected with ear seats 6, and bolts 1 7 are threadedly connected between the two ear seats 6 near the front and between the two ear seats 6 near the back;

[0039] When using the line clearing tool, loosen the two bolts 7 to separate the front and rear pairs of ear seats 6. Then, rotate the lower shell 2 to place the cable between the upper shell 1 and the lower shell 2. Repeat the above steps in reverse to install the clearing tool on the cable surface for deicing and clearing.

[0040] In this embodiment, three gears 11 penetrate the front part of the fixing ring 9 and are fixedly connected with three arc-shaped limit blocks 15 respectively, and the gear 11 is meshedly connected with the inner ring of the half gear ring 10.

[0041] In this embodiment, the arc-shaped limit block 15 is adaptively matched with the arc-shaped groove 36 , and one end of the threaded crushing wheel 16 is adaptively matched with the inside of the arc-shaped limit block 15 .

[0042] In this embodiment, a spiral advancing structure 4 is provided at the rear of the upper shell 1 and the lower shell 2, and the spiral advancing structure 4 includes two half-toothed rings 2 18. The rear of the upper shell 1 and the lower shell 2 is symmetrically connected to three gears 3 19 along the center of the circle. The front of the three gears 3 19 between the upper shell 1 and the lower shell 2 is rotatably connected to a universal joint 20, and one end of the three threaded crushing wheels 16 passes through three arc-shaped limit blocks 15 respectively and is also fixedly connected to the universal joint 20. A telescopic rod 21 is fixedly connected between the universal joint 20 located in front of the gear 3 19 and the universal joint 20 located at one end of the threaded crushing wheel 16. The rear of the upper shell 1 is rotatably connected to a gear 4 22 near the top. A through groove 2 is provided at the top of the upper shell 1 at the rear of the gear 4 22, and a motor 2 23 is fixedly installed inside the through groove 2.

[0043] Start motor 2 23 to drive gear 4 22 to rotate, which in turn drives the half-toothed ring 2 18 near the top to rotate. The half-toothed ring 2 18 near the top rotates against the half-toothed ring 2 18 near the bottom, so that the two half-toothed rings 2 18 rotate synchronously, driving the three gears 3 19 to rotate, and then through multiple universal joints 20 to cooperate with the three telescopic rods 21 to rotate, drive the three threaded breaking wheels 16 to rotate synchronously, and then drive the cable clearing tool to advance in a spiral manner. The three threaded breaking wheels 16 rotate synchronously to break the ice on the surface of the cable. Due to the cooperation of the telescopic rod 21 and the universal joint 20, the threaded breaking wheel 16 can be driven even if it is displaced.

[0044] In this embodiment, the output shaft of motor two 23 passes through slot two and is fixedly connected to gear four 22, the front parts of the three gear three 19 respectively pass through the rear part of the upper shell 1 and the rear part of the lower shell 2, and the three gear three 19 are respectively fixedly connected to the three universal joints 20 located at the front parts of the three gear three 19.

[0045] In this embodiment, gear three 19 is meshedly connected with the inner ring of half gear ring two 18, gear four 22 is meshedly connected with the outer ring of half gear ring two 18, two limiting blocks 24 are fixedly installed inside the fixed end of the telescopic rod 21, and two straight grooves 25 are provided on the outer surface of the movable end of the telescopic rod 21. The limiting blocks 24 are adaptively matched with the straight grooves 25. Through the cooperation between the straight grooves 25 and the limiting blocks 24, the telescopic rod 21 will not rotate during the transmission process of the universal joint 20.

[0046] In this embodiment, a through groove 3 is provided on the outer surface of the upper shell 1 between the two gears 2 12, and a connecting shaft 17 is rotatably connected inside the through groove 3. The two ends of the connecting shaft 17 are respectively fixedly connected to the two gears 2 12, and a battery 37 is fixedly connected to the top of the upper shell 1. The battery 37 can be connected to the motor 1 13 and the motor 2 23 through external wires, and then the motor 1 13 and the motor 2 23 are powered by the battery 37.

[0047] The starting motor 13 drives the rear gear 2 12 to rotate, and then drives the front gear 2 12 to rotate through the connecting shaft 17, so that the front and rear adaptive clamping structures 3 operate synchronously, and then the distance between the three threaded crushing wheels 16 is adjusted at a uniform and stable speed.

[0048] Embodiment 2, as Figure 8-Figure 10 As shown, both sides of the upper shell 1 and the lower shell 2 are provided with a support and restriction structure 5, and the support and restriction structure 5 includes a rotating leg 27 and two sliding legs 28. One side of the lower shell 2 is symmetrically fixedly connected to two fixed blocks 26 near the front and rear parts. The two rotating legs 27 are respectively rotatably connected to the two fixed blocks 26. The side of the fixed block 26 penetrates one side of the rotating leg 27 and is threadedly connected to the fixed block 26 with a screw 1 32. The two sliding legs 28 are respectively slidably connected to the inside of the two rotating legs 27. The inside of the rotating leg 27 penetrates the top to open a top groove 31. The top of the rotating leg 27 penetrates the top groove 31 and is threadedly connected to the top of the sliding leg 28 with a bolt 2 30. The two sides and adjacent parts of the two rotating legs 27 are rotatably connected with forward wheels 29. One side of the two sliding legs 28 penetrates one side to open a through groove 33.

[0049] When the obstacle removal device is performing de-icing and obstacle removal operations on ground cables, the plurality of screw rods 32 are loosened, the four rotating legs 27 are rotated to a vertical state, the four screw rods 32 are tightened, and the four bolts 2 30 are loosened, and the sliding legs 28 are slid along the top groove 31 so that the forward wheel 29 contacts the ground. At this time, the four bolts 2 30 are tightened again, and the four counterweights 34 are connected to the four sliding legs 28 through the plurality of screw rods 2 35 and the plurality of through grooves 33. The total gravity of the four counterweights 34 is greater than that of the three threaded crushing wheels 1 6, so that the four counterweights 34 restrict the spiral movement of the line clearing device, so that when the three threaded crushing wheels 16 rotate synchronously, they can only drive the line clearing tool to move horizontally along the cable. The four sliding legs 28 support the line clearing tool, sharing the gravity of the cable clearing tool required to bear the cable, avoiding the ground cable from being unable to stably support the line clearing tool due to its low structural strength, which not only makes the cable deicing operation unable to be carried out effectively, but also causes the cable to be damaged due to compression deformation.

[0050] In this embodiment, counterweight blocks 34 are provided on one side and the other side of the two pairs of sliding legs 28 located on the same side, and screw rod 2 35 is threadedly connected between the front and rear parts of the two counterweight blocks 34, and screw rod 2 35 passes through the through groove 33. An insert block 8 is fixedly connected to one side of the top of the lower shell 2, and a slot matching the insert block 8 is opened at the bottom of the upper shell 1.

[0051] It should be noted that the present invention is a line obstacle clearing tool. When using the line obstacle clearing tool, loosen the two bolts 7 to separate the front and rear pairs of ear seats 6. At this time, the lower shell 2 can be rotated, and the cable can be placed between the upper shell 1 and the lower shell 2. Then, repeat the above steps in reverse to install the obstacle clearing tool on the cable surface, and then perform de-icing and obstacle clearing operations on it.

[0052] Start the motor 23, drive the gear 4 22 to rotate, and then drive the half-toothed ring 2 18 near the top to rotate, the half-toothed ring 2 18 near the top rotates against the half-toothed ring 2 18 near the bottom, so that the two half-toothed rings 2 18 rotate synchronously, drive the three gears 3 19 to rotate, and then through multiple universal joints 20 to cooperate with the three telescopic rods 21 to rotate, drive the three threaded crushing wheels 16 to rotate synchronously, and then drive the cable obstacle clearing tool to advance spirally, the three threaded crushing wheels 16 rotate synchronously to break the ice layer on the cable surface, due to the cooperation of the telescopic rod 21 and the universal joint 20, even if the threaded crushing wheel 16 is displaced, it can still be driven;

[0053] Start the motor 13 to drive the rear gear 2 12 to rotate, and then drive the top half-toothed ring 10 to rotate, and rotate synchronously with the bottom half-toothed ring 10, so that the two half-toothed rings 10 rotate together, drive the three gears 11 to rotate, and then drive the three arc-shaped limit blocks 15 to rotate. The three arc-shaped limit blocks 15 rotate through the three arc-shaped grooves 36 respectively, drive the three threaded crushing wheels 16 to drive the three telescopic blocks 14 to contract, so that the distance between the three threaded crushing wheels 16 becomes larger, so that the cable with a larger diameter can be clamped by the three threaded crushing wheels 16;

[0054] The starting motor 13 drives the rear gear 2 12 to rotate, and then drives the front gear 2 12 to rotate through the connecting shaft 17, so that the front and rear adaptive clamping structures 3 operate synchronously, and then the distance between the three threaded crushing wheels 16 is adjusted at a uniform and stable speed;

[0055] When the obstacle removal device is performing de-icing and obstacle removal operations on ground cables, the plurality of screw rods 32 are loosened, the four rotating legs 27 are rotated to a vertical state, the four screw rods 32 are tightened, and the four bolts 2 30 are loosened, and the sliding legs 28 are slid along the top groove 31 so that the forward wheel 29 contacts the ground. At this time, the four bolts 2 30 are tightened again, and the four counterweights 34 are connected to the four sliding legs 28 through the plurality of screw rods 2 35 and the plurality of through grooves 33. The total gravity of the four counterweights 34 is greater than that of the three threaded crushing wheels 1 6, so that the four counterweights 34 restrict the spiral movement of the line clearing device, so that when the three threaded crushing wheels 16 rotate synchronously, they can only drive the line clearing tool to move horizontally along the cable. The four sliding legs 28 support the line clearing tool, sharing the gravity of the cable clearing tool required to bear the cable, avoiding the ground cable from being unable to stably support the line clearing tool due to its low structural strength, which not only makes the cable deicing operation unable to be carried out effectively, but also causes the cable to be damaged due to compression deformation.

[0056] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
