Description

Technical Field

[0001] The invention relates to the technical field of pole tower insulator replacement, and in particular to an insulator replacement matching tool capable of live-line operation. Background Art

[0002] An insulator is a component used in power systems and equipment. Its main function is to isolate the conductive part from the ground or other conductive parts to prevent current leakage and short circuit. An insulator string is a structure formed by connecting multiple insulators together. It is mainly used in high-voltage transmission lines. The main function of an insulator string is to provide sufficient electrical insulation and support the weight of the conductor to ensure the safety and stability of the power system. Over time and due to environmental influences, the insulator string may deteriorate or be damaged. Therefore, specific insulating tools are required to regularly replace the insulator string.

[0003] For example, announcement number CN117134248A discloses a double-connected tension insulator string replacement tool, which includes a bottle supporting cloth, a first adjustment mechanism and a second adjustment mechanism. The first adjustment mechanism and the second adjustment mechanism are arranged on the left and right sides of the bottle supporting cloth. The first adjustment mechanism and the second adjustment mechanism are connected to the bottle supporting cloth through a pull rope, and the first adjustment mechanism and the second adjustment mechanism are respectively arranged on the outer sides of the first adjustment mechanism and the second adjustment mechanism.

[0004] During use, after the operator arrives at the designated position, he / she fixes the first adjustment mechanism on the crossarm end connecting plate through the first clamp, and fixes the second adjustment mechanism on the conductor end connecting plate through the second clamp, thus completing the installation work. Then, the first adjustment mechanism and the second adjustment mechanism respectively unfold the bottle supporting cloth through the pull rope, and through the lifting and translation mechanism and the angle adjustment mechanism, the bottle supporting cloth is made to fit tightly to the insulator string, and the entire string of insulators is lifted up, so as to carry out the replacement of a single piece or an entire string of double-connected tension insulators.

[0005] This replacement tool can effectively prevent the probability of insulators falling, thereby improving the safety of insulator string replacement. However, when using this tool, it needs to be used in conjunction with other tools for replacing insulator strings, such as wire connection and fixing tools and insulator string lowering tools. There are many applicable tools and they are difficult to carry. Secondly, if the insulator strings on both sides of the crossarm need to be replaced, the position of the connection and fixing tools needs to be adjusted and re-fixed, which greatly reduces the replacement efficiency. At the same time, the tool uses electrical equipment such as cylinders, winches and motors, which poses a great safety hazard.

[0006] Therefore, a novel insulator replacement matching tool capable of live operation can be adopted to solve the deficiencies of the prior art. Summary of the invention

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example 1: Reference Figure 1-Figure 3An insulator replacement matching tool capable of live working comprises two cross arms 2 fixedly mounted on a pole tower 1, two insulator strings 3 fixedly mounted on the two cross arms 2, and each insulator string 3 is fixedly connected with an electric wire 6.

[0043] The pole tower 1, cross arm 2, insulator string 3 and wire 6 are all existing equipment and will not be described in detail here. There is a gap between the cross arm 2 and the pole tower 1, rather than being in a close fit, which is an existing design. The insulator string 3 and the cross arm 2 are fixed by positioning M pins, and the positioning M pins can be removed by pin pulling pliers (the pin pulling pliers are existing tools and will not be described in detail here).

[0044] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 1-Figure 9 The replacement matching tool also includes a fixing part, a lifting part and a wire pulling part. The fixing part is used to fix the entire matching tool between the two cross arms 2 to improve the stability of the tool when in use. The fixing part includes a locking assembly and an upper clamping plate 13;

[0045] The locking assembly includes an upper splint 4, an adjustment mechanism is installed between the upper splint 4 and the upper splint 2 13, the lower splint 12 and the lower splint 2 14 are respectively installed on the upper splint 14 and the upper splint 2 13 through two elastic telescopic rods 18, two telescopic tubes 43 are fixedly installed between the upper splint 14 and the upper splint 2 13 and between the lower splint 12 and the lower splint 2 14, and the end faces of the upper splint 4, the lower splint 12, the upper splint 2 13 and the lower splint 2 14 are all L-shaped.

[0046] The upper splint 4 is provided with a plurality of storage grooves, each of which is fixedly installed with an elastic telescopic rod 25. The telescopic ends of the plurality of elastic telescopic rods 25 are jointly fixedly installed with a clamping plate 15, and the end face shape of the clamping plate 15 is similar to a trapezoidal shape. The gap between the upper splint 4 and the clamping plate 15 is aligned with the cross arm 2, and then the upper splint 4 is pressed downward. Under the action of pressure, the clamping plate 15 and the upper splint 4 are automatically separated, and the cross arm 2 is clamped by the elastic telescopic rod 25, and then the lower splint 12 is pulled down to extend the elastic telescopic rod 18 until the lower splint 12 and the upper splint 4 clamp the cross arm 2, and keep the sides of the upper splint 4 and the lower splint 12 in contact with the cross arm 2. At this time, under the action of the telescopic tube 43, the lower splint 14 and the lower splint 12 are also driven to move synchronously, completing the initial locking of the upper splint 4 and the lower splint 12.

[0047] The adjusting mechanism includes a screw rod 19 rotatably mounted on the upper clamping plate 1 4, a nut 23 is threadedly rotatably mounted on the screw rod 19, a disc is fixedly mounted on the nut 23, and the disc is fixedly connected to the upper clamping plate 2 13 through a plurality of support rods 24, and a driving structure is installed between the lower clamping plate 12 and the screw rod 19.

[0048] The driving structure includes a connecting telescopic rod 21 rotatably mounted on the lower clamping plate 12, and the telescopic end of the connecting telescopic rod 21 is connected to the screw rod 19 through a bevel gear set 22. The bevel gear set 22 is composed of two bevel gears, one of which is fixedly connected to the screw rod 19, and a column is fixedly mounted on the bottom of the other bevel gear, which is rotatably connected to the upper clamping plate 4, and the column is fixedly connected to the telescopic end of the connecting telescopic rod 21, so as to ensure that the two bevel gears of the bevel gear set 22 will not be separated when the connecting telescopic rod 21 is extended.

[0049] The end of the connecting telescopic rod 21 away from the bevel gear set 22 is fixed with a docking rod 5 by bolts. Before installing the upper clamp plate 4, the lower clamp plate 12, the upper clamp plate 13 and the lower clamp plate 14, the docking rod 5 needs to be installed on the connecting telescopic rod 21. The lower clamp plate 12 is pulled to move by the docking rod 5. The connecting telescopic rod 21 and the lower clamp plate 12 are rotatably connected, which can drive the lower clamp plate 12 to move without affecting the rotation of the connecting telescopic rod 21.

[0050] Then, by rotating the docking rod 5, it is necessary to press the docking rod 5 upwards to ensure that the lower clamping plate 12 is always against the bottom of the cross arm 2 to prevent the lower clamping plate 12 from being separated from the cross arm 2. The rotation of the docking rod 5 will drive the connecting telescopic rod 21 to rotate (as the distance between the upper clamping plate 4 and the lower clamping plate 12 increases, the connecting telescopic rod 21 will also be stretched), thereby driving the screw rod 19 to rotate through the bevel gear set 22, and the rotation of the screw rod 19 drives the nut 23 to move on the screw rod 19. Thereby, the upper clamp plate 13 and the lower clamp plate 14 are driven to move to the side away from the upper clamp plate 1 4 through the support rod 24 until the upper clamp plate 13 and the lower clamp plate 14 clamp the other cross arm 2, thereby completing the support assembly of the tool (the above mentioned need to make the upper clamp plate 1 4 and the lower clamp plate 12 always close to the side of the cross arm 2, the purpose of which is to keep the upper clamp plate 13 and the lower clamp plate 14 level when moving, and ensure that the lower clamp plate 14 and the upper clamp plate 13 can successfully clamp the other cross arm 2).

[0051] Embodiment 3: This embodiment is different from the technical solution of Embodiment 2 in that: Figure 1 , Figure 10-11 The hoisting part includes a binding component and a hoisting component. The binding component is used to bind the insulator string 3 to prevent the insulator string 3 from falling, and the hoisting component is used to hoist and lower the insulator string 3.

[0052] The lifting assembly includes a strap 27, two clamping columns 26 are fixedly installed at the bottom of the strap 27, two clamping grooves corresponding to the clamping columns 26 are provided on the fixed block 16, a turntable 28 is rotatably installed on the strap 27, a connecting ring is rotatably installed on the turntable 28, a suspension rod 7 is fixedly installed on the connecting ring, and an operating rod 10 is rotatably installed on the suspension rod 7.

[0053] After the installation of the fixed part is completed, hold the suspension rod 7 and insert the clamping column 26 into the corresponding clamping groove to complete the installation of the suspension rod 7. The operating rod 10 is installed at one end of the suspension rod 7 and is connected by a buckle. The rotation connection between the operating rod 10 and the buckle can be freely disassembled. After the suspension rod 7 is installed, the buckle on the operating rod 10 is put on the suspension rod 7. When pressing the suspension rod 7 down, it is necessary to apply a force perpendicular to the suspension rod 7 to the operating rod 10. In this way, when driving the suspension rod 7 to rotate around the turntable 28, ensure that the buckle is always put on the suspension rod 7 to prevent the buckle from detaching from the suspension rod 7; at the same time, the purpose of connecting the operating rod 10 and the suspension rod 7 through the buckle is to facilitate the disassembly of the operating rod 10 and the direction of rotating the suspension rod 7.

[0054] The binding assembly includes a fixing ring 9 fixedly mounted on the suspension rod 7, a steel wire rope 29 fixedly connected to the fixing ring 9, a connector 30 fixedly connected to the steel wire rope 29, a self-locking hook 31 rotatably mounted on the connector 30, and a binding rope 32 hung on the self-locking hook 31.

[0055] The binding rope 32 of the self-locking hook 31 is passed around the insulator string 3 from the bottom of the insulator string 3, and then is wound out from the top of the insulator string 3, and then the wound end is clamped in the self-locking hook 31. When the binding rope 32 is tied, it is necessary to divide the binding rope 32 into two strands to bind the two ends of the insulator string 3, which can effectively improve the stability of the insulator string 3 during lifting.

[0056] Embodiment 4: This embodiment is different from the technical solution of embodiment 3 in that: Figure 1-Figure 3 , Figure 12-14 The wire pulling part includes a wire pulling assembly installed on the fixing block 16, which is used to tighten the wire 6 so that the insulator string 3 and the wire 6 remain in a loose state.

[0057] The wire pulling assembly includes two adjustable telescopic rods 20 slidably mounted on the fixed block 16, and the telescopic ends of the two adjustable telescopic rods 20 are fixedly mounted with a moving block 17 that matches the cross arm 2, and a hook 1 33 is fixedly mounted on the moving block 17 and the fixed block 16, and a hook 2 34 is rotatably mounted on the moving block 17;

[0058] The movable block 17 is L-shaped, so when the movable block 17 moves, the L-shape can be attached to the upper surface and the side of the crossarm 2. In this way, when the movable block 17 is pulled (the direction of the force is the direction of the hook 33), the force on the movable block 17 can be directly transferred to the crossarm 2, which has higher stability. When the movable block 17 is pulled from the other side (the direction of the force is the other direction of the hook 33 at this time), although the movable block 17 loses the function of the crossarm 2, part of the force can be transferred to the fixed block 16 by adjusting the telescopic rod 20, which can improve the uniformity of the force and thus improve the stability.

[0059] When a freely movable moving block 17 is used to install the wire pulling part, there is no need to disassemble and reinstall the fixed part, which can greatly improve the replacement efficiency. At the same time, the free movement of the moving block 17 also means that the position of the hook 33 on the moving block 17 can be adjusted to ensure that the position of the hook 33 on the moving block 17 is on the same plane as the wire 6. In this way, it can be ensured that when the wire 6 is tightened, the wire 6 is only tightened without being offset, which is conducive to the disassembly and installation of the insulator string 3.

[0060] The wire pulling assembly also includes a connecting middle arm 8, which is connected to hook one 33 and hook two 34 through a locking buckle. A chain ring on the connecting middle arm 8 is connected to a threaded rod 11, a threaded cylinder is threadedly rotatably installed on the threaded rod 11, a rotating ring 35 is rotatably installed on the threaded cylinder, a circular ring is fixedly installed on the threaded rod 11, a U-shaped clip 36 is fixedly installed on the circular ring and the rotating ring 35, and a clamping mechanism matching the electric wire 6 is installed on both U-shaped clips.

[0061] A connecting middle arm 8 is used here: if a chain-type connection is used, each link connection of the chain will undergo relative rotation, and if the chain needs to be straightened, greater force is required. If the middle part of the chain sinks, each link will undergo relative rotation, so the displacement of the ends of the chain is large when it is straightened. However, if a connecting middle arm 8 is used, only the two ends of the connecting middle arm 8 will undergo relative rotation. Therefore, when it is straightened, the displacement of the ends is less than that of the ends of the chain. Therefore, the displacement of the wire 6 that needs to be adjusted is greatly reduced, which can shorten the time it takes to straighten the wire 6, thereby improving replacement efficiency.

[0062] The clamping mechanism includes an upper clamping block 37 fixedly mounted on the upper part of the U-shaped card 36, a lower clamping block 38 matching the upper clamping block 37 is slidably mounted on the lower part of the U-shaped card 36, a limiting structure and a lifting structure are installed between the lower clamping block 38 and the U-shaped card 36, and the lifting structure includes a threaded sleeve 40 fixedly mounted on the bottom of the U-shaped card 36, a screw 39 threadably connected to the threaded sleeve 40 is rotatably mounted on the lower clamping block 38, a circular hole for the screw 39 to pass through is opened on the U-shaped card 36, and an adjusting ring 41 is fixedly mounted on the bottom of the screw 39.

[0063] Insert the hook on the insulating hook operating rod (an existing rod with a hook design at the end, which can be freely disassembled and replaced with different operating components, such as a screwdriver, a wrench, and pliers, etc.) into the adjusting ring 41, and then drive the U-shaped card 36 to move, so that the upper clamping block 37 on the upper part of the U-shaped card 36 is placed on the wire 6, and then use the insulating hook operating rod to rotate the adjusting ring 41, thereby driving the screw rod 39 to rotate, and under the action of the threaded sleeve 40, the screw rod 39 drives the lower clamping block 38 to move upward, and cooperates with the upper clamping block 37 to clamp and lock the wire 6. In the process of clamping the wire 6, it is necessary to keep the connection between the threaded rod 11 and the connecting middle arm 8 straight.

[0064] After the wire 6 is clamped, the hook on the insulating hook operating rod is replaced with a wrench, and then the threaded barrel is twisted by the wrench to make the threaded barrel drive the U-shaped clip 36 to move on the threaded rod 11, so as to straighten the wire 6. At this time, the wire 6 and the insulator string 3 are in a relaxed state and can be disassembled by pliers; the purpose of setting another U-shaped clip 36 is to play a protective role to prevent the first U-shaped clip 36 from loosening or slipping, causing the wire 6 to fall off.

[0065] The limiting structure includes two limiting rods 42 fixedly mounted on the lower clamping block 38. Two limiting through holes corresponding to the limiting rods 42 are provided at the bottom of the U-shaped card 36. The function of this part is to limit the lower clamping block 38 to prevent the lower clamping block 38 from rotating with the screw rod 39, and at the same time, it can also keep the lower clamping block 38 moving vertically upward.

[0066] The specific operation steps of this device are as follows:

[0067] First, install the fixing part on the two cross arms 2. When installing the fixing part, it is necessary to align the hook 33 on the fixing block 16 with the wire 6, and then insert the clamping column 26 into the corresponding clamping slot to complete the installation of the suspension rod 7;

[0068] Then, the binding rope 32 is tied to the insulator string 3. If the binding rope 32 is too long, it can be wound several times according to its length, and the wound end is hung on the self-locking hook 31 and locked. Then, the operator puts the operating rod 10 on the suspension rod 7, rotates the suspension rod 7, and makes the self-locking hook 31 located just above the insulator string 3, so as to keep the steel wire rope 29 straight.

[0069] Finally, the wire 6 is straightened by the wire pulling part so that the wire 6 and the insulator string 3 are in a relaxed state, and then the positioning M pin connecting the insulator string 3 and the wire 6 is removed by using pliers, and then the suspension rod 7 is rotated to remove the insulator string 3 suspended on the binding rope 32. If another insulator string 3 is to be replaced, it is necessary to move the moving block 17 to align the hook 33 on the moving block 17 with the other insulator string 3, and then hang the wire pulling part on the hook 33 on the moving block 17, and repeat the above operation.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
