Description

Technical Field

[0002] 35kV lines are a crucial component of my country's power distribution network. Featuring greater transmission capacity and lower line losses than 10kV distribution lines, they are a crucial voltage level in my country's suburban and rural power supply grids. 35kV lines are characterized by long lengths, poor operating environments, and a high concentration of equipment. These lines are susceptible to failures due to atmospheric overvoltage, contamination, or other external factors.

[0051] An embodiment of the present application discloses a 35KV tension insulator string replacement device.

[0052] See also Figure 1 as well as Figure 2 An embodiment of a 35KV tension insulator string replacement device provided in the embodiments of the present application includes:

[0053] A right-angle hanging plate fixture 1, a tension wire fixture 3, two connecting rods 5 and a screw assembly corresponding to the connecting rods 5; a slot cavity is opened on the right-angle hanging plate fixture 1 in the thickness direction, and the two ends of the right-angle hanging plate fixture 1 are respectively connected to the first end of the connecting rod 5 through the screw assembly; a locking part 16 is detachably provided on the slot cavity; the tension wire fixture 3 is fixed on the tension wire 6, and the two ends of the tension wire fixture 3 are respectively connected to the second end of the connecting rod 5; the screw assembly is used to adjust the distance between the right-angle hanging plate fixture 1 and the tension wire fixture 3.

[0054] From the above technical solution, it can be seen that the right-angle hanging plate fixture 1 provided in this application is used to be fixed on the right-angle hanging plate 9 of the cross arm, wherein the locking member 16 provided in conjunction therewith can further improve the stability of the fixation of the right-angle hanging plate 9; the tension conductor fixture 3 provided is used to be fixed on the tension conductor 6; the connection and fixation between the tension conductor fixture 3 and the right-angle hanging plate fixture 1 are then achieved through the screw assembly and the connecting rod 5, and the spacing between the tension conductor fixture 3 and the right-angle hanging plate fixture 1 is adjusted by the screw assembly, thereby tightening the tension conductor 6 to facilitate the replacement of the insulator string 8. The overall structure is suitable for the replacement operation of the insulator string 8 between the right-angle hanging plate 9 and the tension conductor 6, with a simple structure, easy assembly and disassembly, and guaranteed operation efficiency.

[0055] The above is the first embodiment of a 35KV tension insulator string replacement device provided by the embodiment of the present application. The following is the second embodiment of a 35KV tension insulator string replacement device provided by the embodiment of the present application. For details, please refer to Figures 1 to 6 .

[0056] A 35KV tension insulator string replacement device comprises: a right-angle hanging plate fixture 1, a tension conductor fixture 3, two connecting rods 5 and a screw assembly corresponding to the connecting rods 5; a slot cavity is opened on the right-angle hanging plate fixture 1 in the thickness direction, and the two ends of the right-angle hanging plate fixture 1 are respectively connected to the first end of the connecting rod 5 through the screw assembly; a locking piece 16 is detachably provided on the slot cavity; the tension conductor fixture 3 is fixed on the tension conductor 6, and the two ends of the tension conductor fixture 3 are respectively connected to the second end of the connecting rod 5; the screw assembly is used to adjust the distance between the right-angle hanging plate fixture 1 and the tension conductor fixture 3.

[0057] Furthermore, if Figure 1 、 Figure 2 as well as Figure 5 As shown, the screw assembly includes a screw 22, a first nut 21 and a handle 23; the first end of the screw 22 passes upward through the right-angle hanging plate fixture 1, and the second end is connected to the first end of the connecting rod 5; the first nut 21 is rotatably set on the right-angle hanging plate fixture 1, and is threadedly matched with the screw 22; the handle 23 is connected to the first nut 21 for driving the first nut 21 to rotate.

[0058] Specifically, in this embodiment, the two ends of the right-angle hanging plate fixture 1 are respectively provided with a first mounting hole 14 for the screw rod 22 to pass through, and the second end of the screw rod 22 can be Figure 1The U-shaped connector shown is fixedly connected to the connecting rod 5, and there is no specific limitation. The working principle of the screw assembly is as follows: after the right-angle hanging plate fixture 1, the connecting rod 5, the screw assembly and the tension conductor fixture 3 are installed; the handle 23 can be turned remotely by the operating lever to drive the first nut 21 to rotate; the first nut 21 can rotate with the screw rod 22 to rotate. Since the first nut 21 is fixed in the vertical direction, according to the screw principle, the screw rod 22 can also move relative to it, thereby driving the tension conductor fixture 3 to move, adjusting the distance between the tension conductor fixture 3 and the right-angle hanging plate fixture 1, so that the tension conductor 6 can be tightened, which is convenient for the subsequent replacement of the insulator string 8.

[0059] Further, if Figure 1 、 Figure 2 、 Figure 5 as well as Figure 6 As shown, the screw assembly may also include a fixing rod 24 installed and fixed on the first mounting hole 14, which can be fixedly connected by a threaded connection; wherein the fixing rod 24 is provided with a central through cavity for the screw rod 22 to move through; and the first nut 21 can be rotatably installed on the first end of the fixing rod 24, thereby achieving rotational cooperation with the right-angle hanging plate fixture 1; by adding the fixing rod 24, the detachable connection between the first nut 21 and the right-angle hanging plate fixture 1 is facilitated, which is convenient for subsequent replacement and maintenance. The first end of the handle 23 is provided with a first opening for the gear 211 to extend into, and the top is provided with a second opening for the screw 22 to extend out. In order to facilitate the maintenance and replacement of the locking block 231, a cover plate (not shown) can be detachably provided at the bottom of the first end of the handle 23. Figure 6 The diagram shows the state where the cover is removed, which not only provides a certain degree of protection for the locking block 231 but also facilitates maintenance of the locking block 231. When in use, the locking block 231 is engaged with the gear 211 by toggling the lever 232, thereby locking the gear 211, making it easier to turn the handle 23 and improve safety.

[0060] Further, if Figures 1 to 3As shown, the slot cavity includes a first slot portion 11 and a second slot portion 12 distributed perpendicular to the first slot portion 11; the first slot portion 11 passes through the right-angle hanging plate fixture 1 upward at the first end, and the second end is connected to the first end of the second slot portion 12, and two limit blocks are symmetrically provided on the first slot portion 11; a limit space for the right-angle hanging plate 9 to be inserted is formed between the two limit blocks, and an avoidance space is formed between the first end of the second slot portion 12 to avoid the connecting piece 91 between the right-angle hanging plate 9 and the U-shaped ring 10; the locking piece 16 is installed between the two limit blocks. Through this structural design, the right-angle hanging plate 9 is easily inserted without being affected by the U-shaped ring 10 connected to the right-angle hanging plate 9; and the limit block can be used to limit the right-angle hanging plate 9 in the horizontal direction. At the same time, the avoidance space formed between the limit block and the second slot 12 can be used to further limit the connecting piece 91 between the right-angle hanging plate 9 and the U-shaped ring 10. Combined with the use of the locking piece 16, the right-angle hanging plate fixture 1 can be firmly fixed on the right-angle hanging plate 9.

[0061] Further, if Figures 1 to 3 As shown, locking member 16 includes a bolt 161 and a second nut 162 that engages with bolt 161. The threaded shank of bolt 161 is movable through the confined space and extends through the right-angled plate fixture 1. Second nut 162 is sleeved onto the threaded shank of bolt 161 that extends through the right-angled plate fixture 1. When locked, the head of bolt 161 contacts and abuts against the right-angled plate 9. When installing locking member 16, the threaded shank of bolt 161 can be passed through the right-angled plate 9 and the right-angled plate fixture 1, and then locked with second nut 162, thereby clamping the right-angled plate 9 and securing it more securely to the right-angled plate 9. Second nut 162 can be a butterfly nut, without limitation. Of course, locking member 16 can also be a quick-release pin, with an abutment block at one end, so that when the quick-release pin is inserted, the abutment block can abut against the right-angled plate 9. Those skilled in the art can make appropriate modifications based on this, without limitation.

[0062] Further, if Figure 1 、 Figure 2 as well as Figure 4 As shown, the tension conductor fixture 3 includes a fixing base 31 and a clamping mechanism. The clamping mechanism is mounted on the fixing base 31 and has a clamping cavity for the tension conductor 6 to pass through. The clamping mechanism is mounted on the fixing base 31 and then clamps the tension conductor 6 to secure the tension conductor fixture 3.

[0063] Further, if Figure 1 、 Figure 2 as well as Figure 4As shown, the clamping mechanism includes two clamping blocks 34, a first connecting rod 32 corresponding to the clamping blocks 34 one by one, and a second connecting rod 33 corresponding to the clamping blocks 34 one by one; a sliding groove 311 is symmetrically opened on both sides of the center line on the first side surface of the fixed seat 31; the sliding groove 311 is distributed along the bottom of the fixed seat 31 toward the top and is inclined toward the center line; the two clamping blocks 34 are respectively slidably installed on the sliding groove 311 on both sides of the center line, and an arc groove 341 is respectively provided on the facing surface of the two clamping blocks 34; a clamping cavity is formed between the arc grooves 341; the first end of the first connecting rod 32 is respectively hinged to the two ends of the bottom of the fixed seat 31, and the second end is respectively hinged to the second end of the connecting rod 5; the first end of the second connecting rod 33 is respectively hinged to the clamping block 34, and the second end is respectively hinged to the first connecting rod 32.

[0064] Specifically, by utilizing the hinged connection between the first connecting rod 32 and the second connecting rod 33, when the screw assembly is adjusted to move the connecting rod 5 upward, the connecting rod 5 drives the first connecting rod 32 to rotate toward the position of the clamping block 34, and the first connection rotates and drives the second connecting rod 33 to push the clamping block 34 to move; and in this embodiment, the slide groove 311 is along the bottom of the fixed seat 31 toward the top, and is tilted toward the center line, which is convenient for guiding the movement of the clamping block 34. At the same time, it can also provide a certain adjustment space for the clamping block 34 to accommodate more diameter specifications of the tension wire 6 for clamping and fixing. When the screw assembly is adjusted to drive the connecting rod 5 to move upward, the clamping block 34 also has a further clamping force on the tension wire 6 to better tighten the tension wire 6. In this way, the tension wire 6 can be steadily driven to tighten, and the overall installation and disassembly are convenient, further improving the working efficiency. In this embodiment, the clamping block 34 can be slidably installed on the slide 311 by a locking member composed of a threaded pin, a fixed head matched with the threaded pin, and a spring. The installation of the locking member can be, for example, as follows: the threaded pin passes through the clamping block 34 and the slide 311 in sequence and is connected to the fixed head. The spring is sleeved on the threaded pin, and one end contacts and abuts the clamping block 34, and the other end contacts and abuts the fixed head, so that the threaded pin has a tensioning force on the clamping block 34, which can fix the position of the clamping block 34 to a certain extent, and does not affect the movement and adjustment of the clamping block 34 along the slide, making it more convenient for the tension conductor clamp 3 to clamp and install the tension conductor. Those skilled in the art can make appropriate changes based on this, and there is no specific limitation.

[0065] Furthermore, anti-slip grooves are provided on the inner sidewalls of the arc-shaped groove 341. The anti-slip grooves can increase the contact friction between the clamping block 34 and the tension conductor 6, thereby improving the stability of clamping the tension conductor 6.

[0066] Furthermore, the first end of the first connecting rod 32 is hinged to the second end of the connecting rod 5 through the hinge 321; the first end of the hinge 321 is hinged to the first end of the first connecting rod 32, and the second end is hinged to the second end of the connecting rod 5. The first end of the hinge 321 is hinged to the first end of the first connecting rod 32, and the second end is hinged to the second end of the connecting rod 5. The hinge 321 improves the connection and coordination convenience between the first connecting rod 32 and the connecting rod 5. The structure of the hinge 321 can be as follows: Figure 4 As shown, no specific limitation is made.

[0067] Further, if Figure 1 as well as Figure 2 As shown, the apparatus further includes a bottle support; the first end of the bottle support is connected to the right-angled plate fixture 1, and the second end is connected to the tension wire fixture 3. The installation of the bottle support can make the force between the right-angled plate fixture 1 and the tension wire fixture 3 more balanced, and can support the insulator string 8 during the replacement process to prevent the insulator string 8 from tipping over.

[0068] Further, if Figure 1 as well as Figure 2 As shown, the bottle support rack includes at least two guide rods 41, a third connecting rod 44, and a support link plate 42. The support link plate 42 is mounted on the tension wire clamp 7 and connected to the tension wire fixture 3 via the third connecting rod 44. The two ends of the support link plate 42 are respectively provided with limit hooks 43 corresponding to the guide rods 41. The two guide rods 41 are arranged vertically symmetrically, with the first ends of the guide rods 41 hinged to the right-angle hanging plate fixture 1 and the second ends movable through the limit hooks 43. The right-angle hanging plate fixture 1 can be provided with a second mounting hole 15 to facilitate the installation and fixation of the guide rods 41 of the bottle support rack.

[0069] Specifically, the first end of the guide rod 41 can be Figure 1 as well as Figure 2 The fixing member shown is fixedly hinged, and the first end of the guide rod 41 is hinged to the first end of the fixing member, and the second end of the fixing member is fixedly connected to the right-angle hanging plate fixture 1. By setting a limit hook 43, the second end of the guide rod 41 can be flexibly limited without affecting the spacing adjustment between the right-angle hanging plate fixture 1 and the tension conductor fixture 3. In addition, with regard to the installation and fixation of the limit hook 43, the limit hook 43 can be provided with a threaded rod portion that can movably pass through the support link plate 42, and a third nut is rotatably sleeved on the threaded rod portion; a fourth nut is also sleeved on the threaded rod portion; the fourth nut and the third nut form a clamping fixation for the support link plate 42. Furthermore, the spacing between the two guide rods 41 in this embodiment is smaller than the diameter of the insulator string 8, which can better prevent the insulator string 8 from tipping over. Of course, there can be more than two guide rods 41 in this embodiment, and there is no specific limitation.

[0070] Furthermore, in order to facilitate the installation of the third connecting rod 44, a mounting block 312 is provided on the second side surface of the fixing seat 31 in this embodiment, and the mounting block 312 is provided with a mounting groove 313 distributed along the length direction and for one end of the third connecting rod 44 to be movably extended, and the mounting groove 313 is provided with a plurality of mounting holes distributed along the length direction of the mounting groove 313. By selecting different mounting holes to achieve the installation and connection of the third connecting rod 44, the spacing between the right-angle hanging plate fixture 1 and the tension conductor fixture 3 can be adjusted to adapt to the replacement operation of insulator strings 8 of different lengths.

[0071] The above is a detailed introduction to a 35KV tension insulator string replacement device provided in this application. For general technicians in this field, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on this application.
