In this embodiment, a column cap 41 is provided at the free end of the column 4, which can limit the first clamping member 2 and the second clamping member 3 slidably arranged thereon to prevent them from disengaging from the column 4.

[0033] Refer to Figure 1 As shown in the figure, there are a plurality of columns 4 which are arranged around the base 1. A plurality of sliding cylinders 7 are arranged around the outer circumference of the first clamping member 2 and the second clamping member 3 corresponding to the columns 4. The sliding cylinders 7 can slide along the columns 4, so as to drive the first clamping member 2 and the second clamping member 3 to slide along the columns 4. The columns 4 can support the first clamping member 2 and the second clamping member 3, making the operation of the monitoring device more stable.

[0034] Continue to refer to Figure 1 As shown in the figure, there are two lifting rods 5, which are respectively arranged on both sides of the first clamping member 2 and the second clamping member 3. When the lifting rods 5 lift, they can drive the second clamping member 3 to lift, so as to adjust the distance between the two clamping blocks, and can be applicable to the suspension stretching and detection of materials of different lengths. At the same time, by using the supporting effect of the column 4, the lifting process of the second clamping member 3 is more stable, ensuring the operation stability of the entire monitoring device.

[0036] Refer to Figures 1-3As shown, a first groove 22 is formed in the first clamping member 2. First clamping jaws 21 are correspondingly arranged on both sides of the first groove 22. The two first clamping jaws 21 can extend and approach each other along the groove wall of the first groove 22 towards the inside of the first groove 22, so as to clamp the material. Semi-circular clamping openings 8 are correspondingly formed on the clamping sides of the two first clamping jaws 21, which can clamp the material.

Preferably, a rubber strip 9 is fixedly connected to the inner side of the end of the first clamping jaw 21. Preferably, the rubber strip 9 is made of rubber. In this embodiment, by arranging the rubber strip 9, the tiny gap between the first clamping jaw 21 and the material can be filled, thereby increasing the clamping tightness and stability, preventing the material from falling off or loosening due to vibration or external force during the transmission process. The soft material of the rubber strip 9 can reduce the direct friction and extrusion on the surface of the material, reducing the risk of damage to the material during the clamping process, especially for vulnerable or surface-sensitive materials.

[0038] Refer to Figure 1 、 4 As shown, a third groove 32 is formed in the second clamping member 3. Second clamping jaws 31 are correspondingly arranged on both sides of the third groove 32. The two second clamping jaws 31 can extend and approach each other along the groove wall of the third groove 32 towards the inside of the third groove 32, so as to clamp the material. Semi-circular clamping openings 8 are correspondingly formed on the clamping sides of the two second clamping jaws 31, which can clamp the material.

[0039] Refer to Figure 4As shown, at the bottom of the corresponding clamping sides of the two second jaws 31, fourth grooves 35 are provided. A second top plate 33 is provided corresponding to the two fourth grooves 35. Both ends of the second top plate 33 can be placed in the two fourth grooves 35. A second hydraulic rod 34 is provided at the bottom of the second top plate 33. One end of the second hydraulic rod 34 is connected to the bottom of the third groove 35, and the other end is connected to the bottom of the second top plate 33. The second hydraulic rod 34 is located between the two second jaws 31 and can jack up the second top plate 33, thereby tightly pressing the clamped material. Preferably, a rubber strip 9 is fixedly connected to the inner side of the end of the second jaw 31. In this embodiment, the rubber strip 9 is made of rubber. In this embodiment, the rubber strip 9 can fill the tiny gaps between the second jaw 31 and the material, thereby increasing the clamping tightness and stability, preventing the material from falling off or loosening due to vibration or external force during transmission. The soft material of the rubber strip 9 can reduce the direct friction and extrusion on the surface of the material and reduce the risk of damage to the material during clamping, especially for vulnerable or surface-sensitive materials.

[0040] In this embodiment, both the first jaw 21 and the second jaw 31 use a motor as the power source to achieve their telescopic movement in the corresponding grooves.

[0041] Refer to Figures 1-2 As shown, a clamping block 24 is further provided corresponding to the first jaw 21, which can further clamp the material to be detected. Semicircular docking ports are provided at the positions where the two corresponding clamping blocks 24 clamp the material, which can clamp the material. The perpendicularity detector 6 is provided on the clamping block 24 and can monitor the vertical stretching of the material.

[0042] Continue to refer to Figures 1-2 As shown, a fixing frame 23 is provided at the bottom of the clamping block 24. A sliding groove 231 is provided on the fixing frame 23. The bottom of the clamping block 24 is threadedly connected with a limit bolt 241 and slides in the sliding groove 231 under the action of the limit bolt 241. The limit bolt 241 can fix the clamping block 24 at a preset position on the fixing frame 23, thereby clamping materials of different sizes and supporting the perpendicularity detector 6 to monitor the vertical stretching of the material.

[0043] The working principle of a suspension connection fitting and an overhead transmission line stretching monitoring device disclosed in an embodiment of the present invention is as follows: When a user uses the monitoring device, the device can be placed at a specified position. At this time, both ends of the material to be monitored can be placed inside the first jaw 21 and the second jaw 31. Then the user can start the first hydraulic rod 26 and the second hydraulic rod 34. The first top plate 27 at the bottom end of the first hydraulic rod 26 moves inside the first jaw 21, and the first top plate 27 is pressed against the inside of the first jaw 21 to fix one end of the material. The same operation method is used to fix the other end of the material. Then the user can start the lifting rod 5. The length of the lifting rod 5 increases, driving the second clamping member 3 to move vertically upward, and the material can be stretched. At this time, the user can use the laser detector (verticality detector 6) on one side of the clamping block 24 to monitor the vertical stretching of the material. At the same time, the first support member 2 and the second support member 3 can be supported by multiple columns 4 to make the device operate more stably. When the user needs to adjust the position of the clamping block 24, the user only needs to rotate the limit bolt 241 to reduce the fixing force of the limit bolt 241 on the clamping block 24. At this time, the user can move the clamping block 24, and the clamping block 24 slides on the upper surface of the fixing frame 23. When the position of the clamping block 24 is appropriate, the user only needs to rotate the limit bolt 241 in the reverse direction again to fix the clamping block 24, and the distance between the two clamping blocks 24 can be adjusted. The monitoring device can monitor the stretching state of the transmission line and its connection fitting in the vertical direction in real time through the fixing component, and timely detect the slack or excessive tension caused by factors such as wind force, temperature change, and material aging, preventing safety accidents caused by line breakage or fitting failure. Combined with the laser detector (verticality detector 6), when abnormal stretching or stress change is detected, an alarm can be automatically issued to notify the maintenance personnel to deal with it in time. By designing the clamping block 24 with adjustable distance and the laser detector (verticality detector 6), it can adapt to materials of different sizes, such as wires with different diameters and different types of fittings, ensuring the accuracy and effectiveness of monitoring, improving the reliability of the entire transmission system. Precise stretching monitoring helps to evaluate the health status of the transmission system, provides a scientific basis for maintenance and optimization, and reduces resource waste caused by unnecessary replacement or repair. The rubber strip 9 can fill the small gaps between the first jaw 21 and the second jaw 31 and the material, thereby increasing the clamping tightness and stability, preventing the material from falling off or loosening due to vibration or external force during transmission. The soft material of the rubber strip 9 can reduce the direct friction and extrusion on the surface of the material, reducing the risk of damage to the material during clamping, especially for vulnerable or surface-sensitive materials. The universal wheels 11 have the ability to rotate in all directions, making the entire device more flexible and convenient to move or adjust the position. During the maintenance and monitoring of the transmission line, it is often necessary to move and adjust the position of the monitoring equipment. Installing the universal wheels 11 can greatly simplify this process and improve work efficiency.

[0044] In summary, a suspension connection fitting and a vertical tensile monitoring device for an overhead transmission line provided by an embodiment of the present invention have the following beneficial technical effects: Through the fixing component, the device can monitor the tensile state of the transmission line and its connection fittings in the vertical direction in real time, and timely detect the relaxation or excessive tension caused by factors such as wind force, temperature change, and material aging, preventing safety accidents caused by line breakage or fitting failure. Combined with a laser detector, when abnormal tensile or stress changes are detected, an alarm can be automatically issued to notify maintenance personnel to handle it in a timely manner. By designing the clamp blocks and laser detectors with adjustable spacing, it can adapt to different sizes of materials such as wires with different diameters and different types of fittings, ensuring the accuracy and effectiveness of monitoring, improving the reliability of the entire power transmission system. Precise tensile monitoring helps to evaluate the health status of the power transmission system, provides a scientific basis for maintenance and optimization, and reduces resource waste caused by unnecessary replacement or repair.
