For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 1 , Figure 2 As shown, a suspension clamp 200 assembly of a preferred embodiment of the present invention comprises: a suspension clamp 200, a tool 100 and a detection assembly 300;

[0030] The tooling 100 includes a base 3 and a first elastic clamp arm 1 and a second elastic clamp arm 2 respectively mounted on the left and right sides of the base 3. The bottom ends of the first elastic clamp arm 1 and the second elastic clamp arm 2 are respectively fixed to the base 3. The detection assembly 300 is mounted on the bottom of the base 3. The outer surface of the detection assembly 300 is a convex smooth curved surface. The first elastic clamp arm 1 is provided with a first through-hole 11. The second elastic clamp arm 2 is provided with a second through-hole 21 at a position opposite to the first through-hole 11. The second through-hole 21 has a notch that runs through the front / rear side edge of the second elastic clamp arm 2. The first elastic clamp arm 1, the second elastic clamp arm 2 and the base 3 are jointly defined to form an installation groove 4. The suspension wire clamp 200 is engaged in the installation groove 4. The suspension wire clamp 200 assembly also includes a connector, which passes through the first through-hole 11, the suspension wire clamp 200 and the second through-hole 21 in sequence to achieve the connection between the suspension wire clamp 200 and the tooling 100. There is no need for manual inspection using drones on a daily basis, which reduces the difficulty of detection. The tool 100 only requires the first elastic clamp arm 1, the second elastic clamp arm 2 and the base 3, and has a simple structure and is easy to produce. The installation steps are few and the installation speed is fast.

[0031] The working process of the present invention is as follows: the transmission line to be detected is fixed in the suspension clamp 200, the detection assembly 300 is slidably installed in the slide groove 31, the installation and removal of the detection assembly 300 is simple and fast, and the bolt member passes through the first through-hole 11 and the second through-hole 21 in sequence to fix the suspension clamp 200 and the tooling 100. The detection assembly 300 is engaged with the tooling 100, and the tooling 100 and the suspension clamp 200 vibrate at the same frequency, so that the detection assembly 300 and the transmission line vibrate at the same frequency, and the detection assembly 300 obtains the vibration frequency of the wire, and the real-time vibration frequency of the wire obtained by the detection assembly 300 is compared with the normal wire vibration frequency in the database. If the deviation is large, an alarm is issued.

[0032] like Figure 6 As shown, further, the outer surface of the detection component 300 is ellipsoidal. Since the surface of the detection component 300 is ellipsoidal with a smooth curved surface, the wind resistance is reduced, the vibration of the detection component 300 caused by natural wind is weakened, and interference with the detection component 300 in collecting vibration data of the suspension clamp 200 is avoided.

[0033] Figure 4 Combination Figure 6 As shown, further, a slide groove 31 is provided at the bottom of the base 3, and a slider 301 is provided on the detection component 300, and the slider 301 is slidably inserted in the slide groove 31. Fixing the detection component 300 and the tooling 100 by sliding, the installation speed is fast and the installation steps are few.

[0034] like Figure 4As shown, further preferably, the slide slot 31 is a T-slot to prevent the detection assembly 300 from being separated from the slide slot 31. A stopper is provided at one end of the slide slot 31 close to the second elastic clamp arm 2 to prevent the monitoring device from slipping along the direction in which the slide slot 31 extends.

[0035] like Figure 3 to Figure 5 As shown, further, the first through-hole 11 is a circular hole, the periphery of the second through-hole 21 includes an arc segment 211 and an inclined segment 212, the end of the arc segment 211 is connected to the head end of the inclined segment, a gap is defined between the head end of the arc segment 211 and the end of the inclined segment 212, the diameter of the first through-hole 11 is the same as the diameter of the arc segment 211, and the central axis of the first through-hole 11 and the central axis of the arc segment 211 do not coincide. By non-coaxially arranging the first through-hole 11 and the second through-hole 21, the mounting seat is deformed, and the slide groove 31 is also deformed accordingly, so that the engaging detection component 300 is more secure, and the detection component 300 is prevented from slipping out of the slide groove 31.

[0036] like Figure 3 As shown, further, the slide groove 31 extends in the left-right direction, and the central axis of the first through hole 11 and the central axis of the arc segment 211 are arranged at an interval of 0.9 mm to 1.1 mm. When the mounting seat is deformed, the slide groove 31 is also deformed, with the middle lower and the two ends higher, so that the detection component 300 is more firmly engaged, and the detection component 300 is further prevented from slipping out of the slide groove 31.

[0037] Furthermore, a plurality of deformation grooves 22 are respectively provided along the front and rear sides of the second elastic clamp arm 2, and the deformation grooves 22 on both sides are arranged in an up-down interval and in a staggered manner from left to right. The plurality of staggered deformation grooves 22 allow the second elastic clamp arm 2 to have more deformation space, and the second elastic clamp arm 2 is retractable. When the transmission line vibrates abnormally, the service life of the second elastic clamp arm 2 is extended, and the detection assembly 300 and the suspension clamp 200 can be continuously fixed by the tooling 100 to continuously feed back monitoring data.

[0038] like Figure 5 As shown, further, a groove 32 is provided in the middle of the top surface of the base 3, the groove 32 extends in the front-to-back direction and respectively penetrates the front and rear sides of the base 3, and a convex portion is provided at the bottom of the suspension wire clamp 200 to fit in the groove 32. Since the first through-hole 11 and the second through-hole 21 are not coaxially arranged, when the bolt member fixes the first through-hole 11 and the second through-hole 21, the groove 32 assists the base 3 to deform, ensuring that the slide groove 31 also deforms with the deformation of the mounting seat, so as to realize the locking tool 100 and the detection component 300.

[0039] like Figure 5As shown, further, the first elastic clamp arm 1 includes a first clamping section 12 and a second clamping section 13, the bottom of the first clamping section 12 is fixedly connected to the base 3, the top of the first clamping section 12 is fixedly connected to the bottom of the second clamping section 13, the first through hole 11 is opened on the clamping section of the second clamping section, and the second clamping section 13 is inclined from the bottom to the top and gradually approaches the second elastic clamp arm 2.

[0040] Furthermore, the thickness of the first clamping section 12 is greater than the thickness of the second clamping section 13; and / or, the first elastic clamping arm 1, the base 3 and the second elastic clamping arm 2 are integrally formed sheet metal parts. Since the first clamping section 12 and the second clamping section 13 have an angle, the first elastic clamping arm 1 provides a centripetal clamping force to strengthen the connection between the tooling 100 and the suspension wire clamp 200. By adopting an integral molding process for the tooling 100, the entire manufacturing process of the tooling 100 can be completed in a short time, thereby improving production efficiency and reducing labor costs.

[0041] Furthermore, the suspension clamp 200 is provided with a wire groove 201 extending in the front-to-back direction, and the bottom surface of the wire groove 201 is in an arc shape that bulges upward. The wire groove 201 is provided with an arc surface, which can effectively buffer the vibration of the wire caused by wind, reduce the wear of the transmission line, and prevent the transmission line from breaking. The vibration data of the transmission line obtained by installing the detection component 300 on the embodiment of the present invention later is also more accurate.

[0042] In summary, the embodiment of the present invention provides a suspension wire clamp 200 component, and its beneficial effects include: 1. Instead of daily inspections of transmission lines by humans and drones, there is no need for workers who are proficient in drones to go to the site, which greatly reduces labor costs; 2. By installing a monitoring component to detect the vibration signal of the transmission line, the real-time vibration signal of the transmission line is compared with the signal in a normal state to determine whether the transmission line has defects, thereby reducing the error caused by human factors when manually comparing photos; 3. The detection component 300 is slidably installed on the slide groove 31, which is easy to install and has a fast installation speed; 4. The detection component 300 provides real-time feedback, and the feedback of the detection results is timely.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
