Description

Technical Field

[0002] The 35kV line is an important part of China's distribution lines. It has the characteristics of a larger transmission capacity and a smaller line loss compared to the 10kV distribution line, and is an important voltage level for the urban suburban and rural power supply networks in China. The 35kV line has the characteristics of a long line, a poor operating environment, and a large number of devices, and is prone to failures under atmospheric overvoltage, pollution, or other external factors.

[0050] Please refer to Figure 1 and Figure 2 , an embodiment of an insulator string replacement device provided in the embodiments of the present application includes:

[0051] A right-angle hanger clamp 1, a strain conductor clamp, two connecting rods 5, and a lead screw assembly corresponding to the connecting rod 5 one by one; a first slot cavity is formed in the right-angle hanger clamp 1 in the thickness direction, and both ends of the right-angle hanger clamp 1 are respectively connected to the first end of the connecting rod 5 through the lead screw assembly; a first locking member 16 is detachably provided on the first slot cavity; the strain clamp 3 is clamped on the strain clamp 6, and both ends of the strain clamp 3 are respectively connected to the second end of the connecting rod 5; the lead screw assembly is used to adjust the distance between the right-angle hanger clamp 1 and the strain clamp 3.

[0052] It can be seen from the above technical solutions that the right-angle hanger clamp 1 provided in the present application is used to be clamped on the right-angle hanger 8 of the cross arm. Among them, the cooperatively provided first locking member 16 can further improve the fixing stability of the right-angle hanger 8; the provided strain clamp 3 is used to be clamped on the strain clamp 6; then, through the lead screw assembly and the connecting rod 5, the connection and fixation between the strain clamp 3 and the right-angle hanger clamp 1 are realized, and the lead screw assembly is used to adjust the distance between the strain clamp 3 and the right-angle hanger clamp 1, so as to be able to tighten the strain clamp 6 to facilitate the replacement of the insulator string 7. The whole is applicable to the replacement operation of the insulator string 7 between the right-angle hanger 8 and the strain clamp 6, with a simple structure, convenient installation and disassembly, and ensuring the operation efficiency.

[0053] The above is the first embodiment of an insulator string replacement device provided in the embodiments of the present application. The following is the second embodiment of an insulator string replacement device provided in the embodiments of the present application. Specifically, please refer to Figures 1 to 6 .

[0054] An insulator string replacement device includes: a right-angle hanger clamp 1, a strain conductor clamp, two connecting rods 5, and a screw rod assembly corresponding to the connecting rod 5 one by one; a first clamping groove cavity is formed in the right-angle hanger clamp 1 in the thickness direction, and both ends of the right-angle hanger clamp 1 are respectively connected to the first end of the connecting rod 5 through the screw rod assembly; a first locking member 16 is detachably arranged on the first clamping groove cavity; the strain clamp 3 is clamped on the strain clamp 6, and both ends of the strain clamp 3 are respectively connected to the second end of the connecting rod 5; the screw rod assembly is used to adjust the distance between the right-angle hanger clamp 1 and the strain clamp 3.

[0055] Further, as Figure 1 , Figure 2 and Figure 5 shown, the screw rod assembly includes a screw rod 22, a first nut 21, and a handle 23; the first end of the screw rod 22 penetrates upward through the right-angle hanger clamp 1, and the second end is connected to the first end of the connecting rod 5; the first nut 21 is rotatably arranged on the right-angle hanger clamp 1 and is in threaded cooperation with the screw rod 22; the handle 23 is connected to the first nut 21 and is used to drive the first nut 21 to rotate.

[0056] Specifically, in this embodiment, first mounting holes 14 for the screw rod 22 to pass through are respectively formed at both ends of the right-angle hanger clamp 1, and the second end of the screw rod 22 can be fixedly connected to the connecting rod 5 through a U-shaped connector as Figure 1 shown, and there is no specific limitation. The working principle of the screw rod assembly is as follows: after the right-angle hanger clamp 1, the connecting rod 5, the screw rod assembly, and the strain conductor clamp are installed; the handle 23 can be rotated remotely through an operating rod to drive the first nut 21 to rotate; when the first nut 21 rotates, it can have a threaded rotational cooperation with the screw rod 22. Since the first nut 21 is fixed in the vertical direction, according to the screw rod principle, the screw rod 22 can also move relatively, so as to drive the strain conductor clamp to move, adjust the distance between the strain conductor clamp and the right-angle hanger clamp 1, tighten the strain conductor, and facilitate the subsequent replacement operation of the insulator string 7.

[0057] Further, as Figure 1 , Figure 2 , Figure 5 and Figure 6As 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. In the present application, in order to facilitate the rotational cooperation between the handle 23 and the first nut 21, a synchronously rotating gear 211 can be sleeved on the first nut 21; and the first end of the handle 23 is sleeved on the gear 211, and a locking block 231 is rotatably provided in the first end of the handle 23 on one side of the gear 211, and the locking block 231 is provided with a locking tooth portion that can be movably engaged with the tooth groove of the gear 211; the locking block 231 is also connected to a lever 232 extending out of the handle 23; specifically, the first end of the handle 23 cooperates with the screw rod 22 and the first nut 21, wherein an avoidance cavity can be provided in the first end of the handle 23 for avoiding the gear 211 and installing the locking block 231, and a first opening for the gear 211 to extend into is provided at the bottom of the first end of the handle 23, and a second opening for the screw rod 22 to extend out is provided at the top; in order to facilitate the maintenance and replacement of the locking block 231, a cover sheet (not shown in the figure) can be detachably provided at the bottom of the first end of the handle 23, Figure 6 The state diagram of removing the cover sheet can provide a certain degree of protection for the locking block 231 and facilitate maintenance of the locking block 231. When in use, the locking block 231 can be meshed with the gear 211 by toggling the lever 232, thereby locking the gear 211, facilitating the use of rotating the handle 23 and improving safety in use.

[0058] Furthermore, if Figures 1 to 3 As shown, the slot cavity includes a first slot portion 11 and a second slot portion 12 vertically distributed with respect 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 with the first end of the second slot portion 12; two limit blocks 13 are symmetrically arranged on the first slot portion 11; a limit space for the right-angle hanging plate 8 to be inserted is formed between the two limit blocks 13, and an avoidance space for avoiding the connecting piece 81 between the right-angle hanging plate 8 and the U-shaped ring 9 is formed between the two limit blocks 13 and the first end of the second slot portion 12; the first locking piece 16 is installed between the two limit blocks 13. This structural design facilitates the insertion of the right-angle hanging plate 8 without being affected by the U-shaped ring 9 connected to the right-angle hanging plate 8; and the limit block 13 can be used to limit the right-angle hanging plate 8 in the horizontal direction. At the same time, the avoidance space formed between the limit block 13 and the second slot 12 can be used to further limit the connecting piece 81 between the right-angle hanging plate 8 and the U-shaped ring 9. Combined with the use of the first locking piece 16, the right-angle hanging plate fixture 1 can be firmly fixed on the right-angle hanging plate 8.

[0059] Further, as shown in Figures 1 to 3 , the first locking member 16 includes a bolt 161 and a second nut 162 that mates with the bolt 161; the threaded rod portion of the bolt 161 passes through the right-angle hanging plate fixture 1 through the limiting space; the second nut 162 is sleeved on the threaded rod portion of the bolt 161 that passes through the right-angle hanging plate fixture 1; in the locked state, the head of the bolt 161 contacts and abuts against the right-angle hanging plate 8. When installing the first locking member 16, the threaded rod portion of the bolt 161 can pass through the right-angle hanging plate 8 and the right-angle hanging plate fixture 1 in sequence and then be tightly fitted with the second nut 162, thereby clamping the right-angle hanging plate 8, so that the right-angle hanging plate 8 can be fixed more firmly on the right-angle hanging plate 8. The second nut 162 can be a wing nut, and there is no specific limitation. Of course, the first locking member 16 can also be a quick-release pin, and a contact block is provided at one end of the quick-release pin, so that the right-angle hanging plate 8 can be abutted by the contact block after the quick-release pin is inserted. Those skilled in the art can make appropriate transformations based on this, and there is no specific limitation.

[0060] Further, as shown in Figure 1 , Figure 2 and Figure 4 , a second card slot cavity 30 is provided on the tension clamp fixture 3 in the thickness direction; a second locking member 31 is detachably inserted into the second card slot cavity 30. The second locking member 31 can be a pin member, and there is no specific limitation; the tension clamp fixture 3 is clamped on the tension clamp 6 as shown in Figure 1 and Figure 2 , and then the second locking member 31 is inserted to complete the locking and fixing.

[0061] Further, a slider 312 is provided on the second locking member 31; a guide rail seat 32 is provided on one side of the second card slot cavity 30 of the tension clamp fixture 3; the slider 312 is slidably matched with the guide rail seat 32. To improve the matching stability of the second locking member 31, the guide rail seat 32 can be added, and the second locking member 31 is slidably installed on the guide rail seat 32. When locking / dismantling is required, the second locking member 31 can be pushed and pulled to complete locking / dismantling; it is more convenient to use. To facilitate the remote operation of tools such as operating rods, a pull ring 311 can also be provided at the first end of the second locking member 31, and there is no specific limitation.

[0062] Further, both ends of the strain clamp fixture 3 are respectively connected to the second end of the connecting rod 5 through a third locking member 34; both ends of the strain clamp fixture 3 are respectively provided with through grooves 33 for the second end of the connecting rod 5 to pass through movably, and first fixing holes communicating with the through grooves 33 are respectively provided on both ends of the strain clamp fixture 3; a plurality of second fixing holes 51 are arranged at intervals along the length direction on the connecting rod 5; the third locking member 34 is respectively inserted and matched with the first fixing hole and the second fixing hole 51. The third locking member 34 can also be a pin shaft member, and no specific limitation is made. Through such a structural design, the distance between the strain clamp fixture 3 and the right-angle hanging plate fixture 1 can be adjusted by matching different second fixing holes 51 with the first fixing hole to meet the replacement requirements of insulator strings 7 with different lengths.

[0063] Further, it further includes a bottle supporting frame; the first end of the bottle supporting frame is connected to the right-angle hanging plate fixture 1, and the second end is connected to the strain clamp fixture 3. The installation of the bottle supporting frame can make the force between the right-angle hanging plate fixture 1 and the strain clamp fixture 3 more balanced, and can support the insulator string 7 during the replacement process to prevent the insulator string 7 from tipping over.

[0064] Further, the bottle supporting frame includes at least two guide rods 41 and limiting hooks 42 corresponding to the guide rods 41 one by one; the limiting hooks 42 are symmetrically installed on the strain clamp fixture 3; the two guide rods 41 are arranged vertically and symmetrically, the first end of the guide rod 41 is hinged to the right-angle hanging plate fixture 1, and the second end passes through the limiting hook 42 movably. In this embodiment, the first end of the guide rod 41 can be hinged to the right-angle hanging plate fixture 1 through a fixing member as shown in Figure 1 and Figure 2 shown, specifically, 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, and no specific limitation is made. The second end of the guide rod 41 passes through the limiting hook 42 movably, which will not affect the distance adjustment between the right-angle hanging plate fixture 1 and the strain clamp fixture 3; similarly, for the installation and fixation of the limiting hook 42, the limiting hook 42 can be provided with a threaded rod portion passing through the strain clamp fixture 3 movably, and a third nut is rotatably sleeved on the threaded rod portion; a fourth nut is also sleeved on the threaded rod portion; the strain clamp fixture 3 is clamped and fixed between the fourth nut and the third nut. In addition, the distance between the two guide rods 41 in this embodiment is smaller than the diameter of the insulator string 7, which can play a good role in preventing the insulator string 7 from tipping over. Moreover, second mounting holes 15 can be respectively provided on the right-angle hanging plate fixture 1 to facilitate the installation and fixation of the guide rods 41. Of course, the number of the guide rods 41 in this embodiment can also be more than two, and no specific limitation is made.

[0065] The above has introduced in detail an insulator string replacement device provided by the present application. For those of ordinary skill in the art, according to the idea of the embodiments of the present application, there will be changes in the specific implementation manners and application scopes.
