[0002] In the power transmission system, the anti-dancing spacer is an important equipment to ensure the safe operation of the high-voltage transmission line, and its main function is to prevent the conductor from swinging violently under severe weather conditions such as strong wind, so as to avoid the mutual collision and wear between the conductors, however, in the actual installation and maintenance process, since these operations usually need to be carried out in the high-altitude environment, the workers face many challenges, especially in the case of limited space of the high-altitude operation platform, the operator not only needs to ensure his own safety, but also needs to deal with the complex installation and adjustment work at the same time, which makes the whole operation process extremely difficult.
[0003] The existing anti-dancing spacer installation device has obvious limitations, due to the particularity of high-altitude operation, workers cannot carry a large amount or heavy tools, which requires the device itself to have portability and multifunctionality, however, the devices on the market are deficient in operation convenience and adjustment flexibility, and often need multiple processes to complete the installation and adjustment, which not only prolongs the operation time, but also increases the operation risk, especially in the case of adjusting the spacer, the functional limitation of the existing device is more obvious, which seriously affects the construction efficiency and installation quality.

[0018] Please see Figures 1 to 8An adjustable anti-danceling spacer includes a fixed frame 11 and a retraction mechanism. The retraction mechanism includes multiple bidirectional blocks 21 evenly spaced on the fixed frame 11. Each bidirectional block 21 is slidably connected to an expansion block 22. A rotating disk 23 is rotatably mounted on the lower end of the fixed frame 11. An expansion bar 24 is mounted on the rotating disk 23. Each expansion block 22 is equipped with a pinching block 25, which is slidably connected within the expansion bar 24. A synchronization sleeve 26 is coaxially mounted on the lower end of the rotating disk 23. A synchronizing block 27 is provided for the limiting sliding connection. A return spring 28 is installed at the lower end of the synchronizing block 27 and abuts against the synchronizing sleeve 26. A synchronizing groove 29 is provided on the side of the fixing frame 11 near the rotating disk 23, and a fixing groove 210 is provided on the fixing frame 11. The retraction mechanism also includes an electric wrench 211, on which a fixing head 212 is fixedly installed. An adjusting head 213 is connected to the extended end of the electric wrench 211, and a universal head 214 is installed on the adjusting head 213. When it is necessary to adjust the position of multiple expansion blocks 22, the... The adjusting head 213 is inserted into the synchronizing sleeve 26, and then the fixing head 212 is inserted into the fixing groove 210. At this time, the rotating disk 23 can be driven to rotate. Each expansion block 22 is fitted with a clamping tube 215. Two embedded grooves 216 are symmetrically opened in the clamping tube 215. A gear disk 217 is slidably connected in each embedded groove 216. A central hole 218 is opened on the clamping tube 215. A bidirectional wheel 219 is slidably connected in the central hole 218. The bidirectional wheel 219 meshes with the two gear disks 217 respectively. Insertion sleeves 220 are installed on the gear disk 217. Two threaded disks 221 are symmetrically threaded inside the clamping tube 215. Insertion slots 222 are opened on the two threaded disks 221 respectively. Insertion sleeves 220 are slidably connected in the insertion slots 222. Multiple inclined blocks 223 are symmetrically and equally spaced at both ends of the clamping tube 215. A shrink block 224 is slidably connected on each inclined block 223. A thrust bearing 225 is fixedly installed on each threaded disk 221. The thrust bearings 225 abut against the multiple shrink blocks 224 respectively.
[0019] Before securing multiple cables, first select the appropriate model of cable clamp 35 and fix the cable clamp 35 and clamping tube 215 on the ground for easy operation at height. Insert the clamping seat 31 on the corresponding cable clamp 35 into the clamping tube 215, and then insert the other side of the clamping tube 215 into the expansion block 22. At this time, insert the universal head 214 on the electric wrench 211 into the double-acting wheel 219. Please refer to [link / reference needed]. Figure 5Then, the two sides of the clamping tube 215 are respectively attached to the expansion block 22 and the clamping seat 31. At this time, starting the electric wrench 211 can drive the rotation of the bidirectional wheel 219. Since the bidirectional wheel 219 is limited and slidably connected in the middle hole 218, the bidirectional wheel 219 will drive the upper and lower gear discs 217 to rotate in opposite directions. The two gear discs 217 are respectively meshed in the inner groove 216, so the gear discs 217 can only rotate in the inner groove 216. Since each gear is equipped with an insertion sleeve 220, please refer to... Figure 6 Then, the insert sleeve 220 is slidably connected in the insert slot 222, which will drive the threaded disc 221 to rotate synchronously. Since the threaded discs 221 on both sides are threadedly connected to the clamping tube 215, they will move towards the shrinking block 224 respectively. Since the two threaded discs 221 are respectively equipped with thrust bearings 225, the rotational thrust will be converted into direct thrust. At this time, multiple shrinking blocks 224 slide and shrink along the inclined block 223. Therefore, the shrinking blocks 224 on both sides will abut against the clamping seat 31 and the expansion block 22 respectively. Multiple clamping tubes 215 perform the above operations respectively, so the wire clamp 35 and the fixing bracket 11 can be connected to complete the preparation work before installation.
[0020] When securing the cables, first clamp them using cable clip 35. This will secure multiple cables individually. After securing, adjust the positions of the cables as needed. Please refer to [link / reference needed]. Figure 3 and Figure 4 First, insert the fixing head 212 on the electric wrench 211 into the fixing slot 210. This will synchronously fix the electric wrench 211 and the fixing bracket 11. At the same time, the universal head 214 will push the synchronizing block 27 downward to compress it, causing the synchronizing block 27 to disengage from the synchronizing slot 29 and continue to compress downward. At this time, the adjusting head 213 will pass through the synchronizing slot 29 and be inserted into the synchronizing sleeve 26. Then, start the electric wrench 211. Since the adjusting head 213 is inserted into the synchronizing sleeve 26, it will only drive the rotating disk 23 to rotate, and the fixing head 212 will not rotate. The fixed groove 210 is in a fixed state, which ensures the limit of the fixed frame 11 and the continuity of rotation. The rotation of the rotating disk 23 will drive the rotation of multiple expansion bars 24. Since the expansion block 22 is slidably connected to the bidirectional block 21 and the pinching block 25 is engaged with the expansion bar 24, it will drive multiple expansion blocks 22 to expand and contract, thereby fixing the cable and preventing the cable from swinging. When operating at height, only the electric wrench 211 needs to be inserted to complete the operation, which improves the convenience and safety of use.
[0021] Please see Figures 7 to 8The clamping mechanism includes a clamping seat 31 and shrink plates 32 installed on both sides of the clamping seat 31. Multiple shrink grooves 33 are symmetrically opened on the shrink plates 32 on both sides. A follower shaft 34 is slidably connected in each pair of left and right symmetrical shrink grooves 33. The clamping mechanism also includes multiple wire clamps 35 attached to both sides. Two follower shafts 34 are rotatably connected to the wire clamps 35 respectively. The multiple wire clamps 35 are respectively clamped on the wire. Two bidirectional sleeves 36 are installed on the two closest follower shafts 34 respectively. Reverse rods 37 are respectively threaded in opposite directions in the two bidirectional sleeves 36.
[0022] When multiple cable clips (35) need to be attached to the cable, please refer to [link / reference]. Figure 7 and Figure 8 First, clamps 35 are used to secure multiple cables. Then, the universal head 214 on the electric wrench 211 is inserted into the reverse rod 37. Rotating the electric wrench 211 causes the reverse rod 37 to rotate synchronously. Since the reverse rods 37 are connected to the two bidirectional sleeves 36 with reverse threads, they expand, which in turn causes the corresponding follower rods to expand along the contraction groove 33. Another follower shaft 34 also expands along the contraction groove 33 on the other side, thus clamping the clamps 35 on both sides onto the cables, completing the fixing process. To untie, simply rotate the wrench in the opposite direction. Therefore, when fixing cables, simply insert the universal head 214 on the electric wrench 211 into the reverse rod 37 and rotate it. One electric wrench 211 can not only clamp the cables but also fix the clamping seat 31 and the expansion block 22, and adjust the distance between multiple expansion blocks 22. This greatly improves versatility and convenience, reduces the difficulty of working at height, and enhances the safety of use.
