[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. A cross-arm adjusting assembly is provided. According to the ambient temperature during installation and the type of cable, rotate the turning handle outside the turning circle to drive the horizontal lead screw to rotate, push the turning block to move along the horizontal lead screw, and at the same time, the turning block also rotates in the turning hole, changing the included angle between the two transmission rods, driving the end pipes on both sides of the middle pipe to move away from each other, thereby changing the state of the cable support, preventing the cable from being bent at too large an angle at the support position and cracking.

[0021] During installation, the middle pipe and the end pipes are at the same height, ensuring that the sag arc of the cable between the power transmission towers is within the specified range. If the temperature rises, the cable between the power transmission towers sags more. Start the adjusting motor, and the adjusting motor drives the vertical lead screw to rotate, driving the middle pipe to move upward. The height of the middle pipe exceeds that of the end pipes, and the middle part of the cable between the two end pipes bulges and bends, changing the length of the cable between the power transmission towers, so that the sag amplitude of the cable between the power transmission towers decreases. When blown by the wind, the swaying amplitude of the cable will also be smaller, reducing the probability of the cable being damaged by swaying and having better safety. When the temperature drops, the cable between the two end pipes resets, changing from bent to straight, increasing the distance between the two power transmission towers to prevent the cable from shrinking too much and breaking due to low temperature. Different coping methods are used in low-temperature and high-temperature environments, making the cable have better environmental adaptability.

[0022] 2. A anti-vibration protection component is provided. After the cable is installed, when the cable sways due to wind, the arc-shaped guide rod is clamped in the arc-shaped card slot to support the transmission rod, preventing the transmission rod from being pulled and bent by the cable. When the transmission rod sways, the rolling ball in the rolling groove will push the ball seat to squeeze the buffer air-filled tube made of rubber for buffering and reducing vibration. When the vibration is transmitted to the installation plate, the buffer airbag and the buffer rubber strip in the installation card slot will deform to absorb the vibration generated by the swaying, reduce the impact force at the connection between the side rod and the installation plate, protect the connection position between the cable and the power transmission tower, and reduce the probability of damage;

[0023] In summary, the cross-arm adjustment component adjusts the length of the cable between adjacent power transmission towers according to temperature, preventing the problem of excessive sag of the cable between adjacent power transmission towers and resulting in too large a sway amplitude. At the same time, it also reduces the amplitude of vibration, which is more conducive to the anti-vibration protection component absorbing vibration. The two components work together to further reduce the vibration, thereby reducing the damage to the connection between the cable and the power transmission tower and improving the safety of power use.

[0044] The mounting plate 301 is provided with mounting card slots 401 corresponding to the side rod 2. A support plate 402 is welded to one side of the side rod 2. Columns 403 are evenly welded to the top surface of the support plate 402. A buffer rubber strip 404 is clamped to the top surface of the support plate 402.

An arc-shaped card slot 416 is provided in the bottom end of the transmission rod 302 corresponding to the arc-shaped guide rods 410.

[0046] The working principle and usage process of the present invention: When it is necessary to install the cross arm, after embedding the buffer airbag 407 into the protective sleeve 406, it is adhered to one side of the mounting card slot 401. The cable passes through the end tube 317 and the middle tube 313 in sequence. The movable support rollers 314 and the fixed support rollers 318 guide and clamp the cable. The end tube 317 and the middle tube 313 are simultaneously lifted and hoisted to the position of the side rod 2. The buffer rubber strip 404 is clamped to the columns 403 of the support plate 402. The mounting card slot 401 is clamped to the side rod 2. The upper screws 408 and the side screws 409 are installed in sequence to fix the mounting plate 301. An annular oil-soaked sponge 322 is placed between the rubber sealing tube 319 and the outer sealing tube 321 to prevent dust from entering the vertical lead screw 310 and the internal thread tube 311 while lubricating. An oil-soaked sponge block 335 is embedded in the bottom surface of the top end cover 334 and clamped and installed at the top end of the protective tube 331 to prevent dust from entering the rotating hole 303 while lubricating, facilitating subsequent adjustment operations;

[0047] According to the ambient temperature during installation, rotate the rotating handle 307 outside the rotating circle 306 to drive the horizontal lead screw 305 to rotate, push the rotating block 304 to move along the horizontal lead screw 305, and at the same time, the rotating block 304 also rotates within the rotating hole 303, driving the transmission rod 302 to rotate, changing the angle between the two transmission rods 302. During the above process, the folding curtain 332 always blocks the rotating hole 303, and the buffer tube 412 slides along the top surface of the arc guide rod 410, driving the end tubes 317 on both sides of the middle tube 313 to move away from each other. At this time, the rotating guide plate 315 is in a horizontal state and slides inside the guiding block 316, thereby changing the state of the support of the cable, preventing the cable from being bent at too large an angle at the support position. Then, start the electric push rod 328, and the pressing roller 330 of the bottom sleeve plate 329 is lifted, squeezing the cable between the upper pressing roller 327 and the lower pressing roller 330 until the arc spring piece 325 deforms and the upper pressing roller 327 presses the anti-slip pad 324, and the upper pressing roller 327 cannot rotate freely, fixing the cable inside the fixed end tube 317;

[0048] During installation, the middle tube 313 and the end tube 317 are at the same height to ensure that the sag arc of the cable between the power transmission towers 1 is within the specified range. If the temperature rises and the cable between the power transmission towers 1 sags more, then start the electric push rod 328 to retract, the upper pressing roller 327 no longer presses the anti-slip pad 324, and the cable between the upper pressing roller 327 and the lower pressing roller 330 can slide freely. Start the adjustment motor 309, the adjustment motor 309 drives the vertical lead screw 310 to rotate, the vertical lead screw 310 pulls the internally threaded tube 311 and the U-shaped frame 312 to move upward, thereby driving the middle tube 313 to move upward. The height of the middle tube 313 exceeds that of the end tube 317, the rotating guide plate 315 tilts and drives the guiding block 316 to rotate. Even if the middle tube 313 rises, it is still in the same plane as the end tube 317, and the middle part of the cable between the two end tubes 317 bulges and bends, thereby changing the length of the cable between the two power transmission towers 1, reducing the sag amplitude of the cable between the power transmission towers 1. When blown by the wind, the swaying amplitude of the cable will also be smaller, reducing the probability of the cable being damaged by swaying and having better safety. When the temperature drops, the cable between the two end tubes 317 resets, increasing the distance between the two power transmission towers 1 to prevent the low-temperature cable from shrinking too much and breaking, making the cable more adaptable to the environment;

[0049] After the cable is installed, when the cable sways due to wind, the arc-shaped guide rod 410 is clamped in the arc-shaped card slot 416 to support the transmission rod 302, preventing the transmission rod 302 from being bent by the cable pull. When the transmission rod 302 sways, the rolling ball 415 in the rolling groove 411 will push the ball seat 414 to squeeze the buffer inflatable tube 413 made of rubber for buffering and reducing vibration. When the vibration is transmitted to the position of the mounting plate 301, the buffer airbag 407 and the buffer rubber strip 404 in the mounting card slot 401 will deform to absorb the vibration generated by the sway, reduce the impact force at the connection between the side rod 2 and the mounting plate 301, protect the connection position between the cable and the power transmission tower 1, and reduce the probability of damage;

[0050] The cross-arm adjustment assembly 3 adjusts the length of the cable between adjacent power transmission towers 1 according to the temperature, preventing the problem that the cable between adjacent power transmission towers 1 sags excessively and causes too large a sway amplitude. At the same time, it will also reduce the amplitude of vibration, which is more conducive to the anti-sway protection assembly 4 absorbing vibration. The two assemblies work together to further reduce the vibration, thereby reducing the damage to the connection between the cable and the power transmission tower 1 and improving the safety of power consumption.

[0051] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
