High-altitude cable quick fixing structure

Abstract

This invention belongs to the field of power engineering technology, and in particular to a rapid high-altitude cable fixing structure, comprising an I-shaped steel frame. The surface of the I-shaped steel frame is provided with a movable component, which includes a rear movable plate located below the I-shaped steel frame. When the air pump is running, gas is injected, driving the front L-shaped movable plate to move via a connecting rod. When the air pump is running, gas is extracted, pulling the rear movable plate to move. This alternation achieves intermittent movement of the entire structure on the I-shaped steel frame. When the front L-shaped movable plate moves, it drives the irregular plate, causing the L-shaped fixing hook plate to rotate around it. When the rear movable plate moves, the L-shaped fixing hook plate rotates under gravity to below the cable. As the entire structure moves, the cable is fitted and fixed within the L-shaped fixing hook plate, achieving rapid and stable fixing of the cable at high altitude.

Description

Technical Field

[0001] This invention belongs to the field of power engineering technology, specifically relating to a rapid fixing structure for high-altitude cables. Background Technology

[0002] In the field of power engineering, the fixing of high-altitude cables (including 10kV distribution network conductors, 35kV and above high-voltage transmission conductors, ground wires, communication optical cables, etc.) is the core process of overhead transmission lines and distribution network laying and operation and maintenance. It is directly related to the safe and stable operation of the power grid, construction efficiency and operation and maintenance costs. As my country's power grid construction moves towards ultra-high voltage, intelligence and wide coverage, the scenarios for laying high-altitude cables are becoming increasingly complex. It not only involves conventional overhead lines in plains areas, but also special working conditions such as mountains, hills, urban building complexes, and crossing railways and highways. This places higher demands on the convenience, stability, adaptability and safety of cable fixing structures. Currently, the fixation of high-altitude cables in power engineering mainly relies on two methods: traditional manual binding and conventional metal clamps. Traditional manual binding uses insulated binding wire, iron wire, etc. as binding materials, and operators manually wrap and fix the cables at high altitudes. Although this method is inexpensive, the high-altitude working space is narrow and the working environment is complex. Working at heights for a long time can easily cause fatigue and increase the safety hazards such as falls and cable detachment. Although existing conventional metal clamps have replaced manual binding to some extent, these clamps are mostly fixed structures and lack movable adjustment functions. Operators need to install and fix them point by point, which restricts the efficiency of the operation.

[0029] Working principle: When this structure is in use, the I-shaped steel frame 1 first serves as a base support rail for cable fixing. According to the overhead cable installation requirements of different application scenarios, a stable building / facility structure such as a wall, ceiling, or support column is selected for installation. After the I-shaped steel frame 1 is installed, two first L-shaped clamping plates 211 and two second L-shaped clamping plates 213 are respectively fitted onto one end of the I-shaped steel frame 1. Under the constraint of the shape of the I-shaped steel frame 1, the height of the structure can be fixed, so that the cable to be installed is placed inside the L-shaped groove 31. At this time, the second conveying roller 32 is in contact with the surface of the cable, so that the air pump 24 and the air blower 23 are connected to the external power supply. If it is inconvenient to connect the air pump 24 and the air blower 23 to the external power supply, a backup power supply can be installed on the structure to facilitate the power supply of the air blower 23 and the air pump 24. The air pump 23 is activated by an external controller. The operation of the air pump 23 injects gas into the fourth three-way connector 28, which then flows into the second sealing groove 220. Simultaneously, the gas flows through the second connecting pipe 210 into the third connecting pipe 212 and the eighth connecting pipe 44. The gas then flows through the third connecting pipe 212 into the hollow cover 238. As the air pump 23 continues to operate, the air pressure on the side of the built-in plate 2401 away from the positioning plate 2405 continuously increases. Due to the elastic potential energy of the third spring 2404, the trapezoidal block 2403 cannot move until the air pressure on the side of the built-in plate 2401 reaches a suitable value. At this time, the air pressure inside the hollow cover 238 continuously increases. Because the second connecting pipe 210 is connected to the first connecting pipe 29, the internal air pressure in the space formed by the second piston 232 and the rear moving plate 21 continuously increases. As the air pressure increases, it drives the second piston 232 to move upwards. The movement of the second piston 232 stretches the second spring 233, which in turn drives the second rubber block 231 to move upwards synchronously until the second rubber block 231 abuts against the bottom surface of the I-shaped steel frame 1. Furthermore, as the air pressure increases, the squeezing force of the second rubber block 231 on the I-shaped steel frame 1 continuously increases. Although some gas flows out from the inside of the second air hole 218 during this process, due to the continuous operation of the air pump 23, it does not affect the air pressure inside the hollow cover 238, and the air pressure continues to increase. During the process, the pressure exerted by the second rubber block 231 on the I-shaped steel frame 1 continuously increases, thereby achieving the effect of fixing the position between the rear moving plate 21 and the I-shaped steel frame 1. The increase in pressure also causes the air pressure to continuously increase the force exerted on the trapezoidal block 2403. When the air pressure is sufficient to allow the trapezoidal block 2403 to continue compressing the third spring 2404, the gas can flow along the gap between the trapezoidal block 2403 and the inner plate 2401 into the space between the two air pressure conveying components 240. Under the action of the U-shaped tube 237, the gas flows into the interior of the sealing cover 235. As the air pressure inside the sealing cover 235 continuously increases, it can push the third piston 239 to slide inside the sealing cover 235. The movement of the third piston 239 is transmitted through a series of... The connecting rod 236 drives the front L-shaped moving plate 22 to move, thereby causing the second L-shaped clamping plate 213 to slide on the surface of the I-shaped steel frame 1. When the third piston 239 drives the connecting rod 236 to move a distance, causing the front L-shaped moving plate 22 to move a certain distance, the operation of the air pump 23 is stopped by the external controller, and the air pump 24 is started. At this time, the gas inside the second sealing groove 220 can be discharged to the outside along the second air hole 218. Under the action of the gravity of the second piston 232 and the tension of the second spring 233, the second piston 232 can move to fit against the top of the second support rod 234. At this time, the second rubber block 231 is no longer in contact with the surface of the I-shaped steel frame 1, thereby releasing the restriction of the fixed position between the rear moving plate 21 and the I-shaped steel frame 1. The operation of the vacuum pump 24 extracts gas from the first three-way connector 25, and extracts gas from the first sealing groove 219 and the fourth connecting pipe 214 through the fifth connecting pipe 215 and the sixth connecting pipe 216 respectively. When the negative pressure does not reach the specified value, the other trapezoidal block 2403 does not move, causing the negative pressure in the space between the first piston 221 and the front L-shaped moving plate 22 to continuously increase. This causes the first piston 221 to move downwards, compressing the first spring 222. The movement of the first piston 221 drives the first toothed plate 224 to move synchronously, and the movement of the first toothed plate 224 drives the gear 22... 8. The rotation of gear 228 causes the second toothed plate 225 to move upward, which in turn causes the first rubber block 226 to move upward until the first rubber block 226 compresses the I-shaped steel frame 1. As the negative pressure increases, the compressive force of the first rubber block 226 on the I-shaped steel frame 1 also increases, thereby achieving the effect of fixing the position between the front L-shaped moving plate 22 and the I-shaped steel frame 1. When the negative pressure on one side of the hollow cover 238 reaches a suitable value, the trapezoidal block 2403 can move to compress the third spring 2404. At this time, the gas inside the sealing cover 235 can flow along the U-shaped tube. The gas flows from inside 237 into the hollow cover 238. As the negative pressure inside the space formed by the third piston 239 and the sealing cover 235 continuously increases, the sealing cover 235 slides on the surface of the third piston 239. The movement of the third piston 239 drives the rear moving plate 21 to move synchronously until the end of the sealing cover 235 away from the rear moving plate 21 is in contact with the surface of the front L-shaped moving plate 22. At this time, the operation of the air pump 24 is stopped. At this time, the external gas can flow into the interior of the first sealing groove 219 along the interior of the first air hole 217. Under the action of the elastic potential energy of the first spring 222, the first piston 221 can move. Moving upwards causes the first rubber block 226 to move away from the I-shaped steel frame 1, thereby releasing the fixed position between the front L-shaped moving plate 22 and the I-shaped steel frame 1. This is beneficial when the air pump 23 is started, so that the position between the rear moving plate 21 and the I-shaped steel frame 1 is fixed, and the front L-shaped moving plate 22 moves a certain distance. When the air pump 24 is started, the fixed position between the rear moving plate 21 and the I-shaped steel frame 1 is released, and the position between the front L-shaped moving plate 22 and the I-shaped steel frame 1 is fixed. At the same time, the rear moving plate 21 can be pulled to move, thereby achieving the effect of intermittent movement of the structure. When the air pump 23 is running, it can increase the air pressure on the side of the two air pressure conveying components 240 that is far apart from each other. When the air pressure on one side of the air pressure conveying component 240 reaches a suitable value, it can push the trapezoidal block 2403 to move. The air pressure on the other side applies a force to the trapezoidal block 2403, making the trapezoidal block 2403 on the other side and the built-in plate 2401 fit tightly together. This improves the utilization rate of gas and avoids the problem of gas leakage seriously affecting work efficiency. When the air pump 24 is running, it can extract the air pressure on the side of the two air pressure conveying components 240 that is far apart from each other. When the negative pressure on one side of the air pressure conveying component 240 reaches a suitable value, it can drive the trapezoidal block 2403 to move. The negative pressure on the other side applies a force to the trapezoidal block 2403. The force makes the trapezoidal block 2403 and the built-in plate 2401 on the other side fit tightly together, further improving the utilization rate of gas and avoiding the problem of gas leakage seriously affecting work efficiency. The first one-way valve 41 and the second one-way valve 42 can make the gas flow in one direction, and the direction of gas flow is irreversible. That is, under the action of the first one-way valve 41, the gas inside the hollow cover 238 can flow into the interior of the seventh connecting pipe 43 along the interior of the first one-way valve 41, and the direction of gas flow is irreversible. Under the action of the second one-way valve 42, the gas inside the eighth connecting pipe 44 can flow into the interior of the hollow cover 238 along the interior of the second one-way valve 42, and the direction of gas flow is irreversible, further ensuring the moving efficiency of the structure. During its movement, the front L-shaped moving plate 22 causes the second L-shaped clamping plate 213 to slide on the surface of the I-shaped steel frame 1. The second L-shaped clamping plate 213, in turn, causes the irregularly shaped plate 36 to move synchronously. Because the irregularly shaped plate 36 slides against the surface of the I-shaped steel frame 1, and because the side of the irregularly shaped plate 36 away from the I-shaped steel frame 1 has an inclined cut surface, during the movement of the irregularly shaped plate 36, when the L-shaped fixing hook plate 33 contacts the inclined cut surface of the irregularly shaped plate 36, the L-shaped fixing hook plate 33 slides against the surface of the irregularly shaped plate 36 under the action of the inclined cut surface on one side of the irregularly shaped plate 36. That is, the L-shaped fixing hook plate 33 rotates on the surface of the positioning pin 34 until it moves to be in contact with the surface of the strip rod 37. Furthermore, as the front L-shaped moving plate 22 continues to move, the L-shaped fixing hook plate 33 can slide to the surface of the square plate 38. During the movement of the square plate 38 driven by the rear moving plate 21, the L-shaped fixing hook plate 33 can slide to the surface of the square plate 38. The cable slides inside the L-shaped groove 31. Under the action of the second conveying roller 32, the frictional resistance during the cable movement can be reduced. As the structure moves, the L-shaped fixing hook plate 33 can rotate around the positioning pin 34. The cable placed inside the L-shaped groove 31 can be lifted from a low position as the rear moving plate 21 moves. As the rear moving plate 21 moves the square plate 38, the L-shaped fixing hook plate 33 can slide out from the surface of the square plate 38. Under the action of gravity, the L-shaped fixing hook plate 33 rotates to a vertical or nearly vertical state, so that the bent part of the L-shaped fixing hook plate 33 rotates to the bottom of the cable. As the rear moving plate 21 moves, the cable can fit into the inside of the L-shaped fixing hook plate 33. With the intermittent movement of this fixing structure, the cable can be fixed inside the L-shaped fixing hook plate 33, thereby achieving the effect of fast cable fixing.
