Description

Technical Field

[0002] In the traditional distribution network overhead line inspection and maintenance, pin insulators play a very important role. Pin insulators can ensure that the conductors, crossarms and towers have sufficient insulation, and play an important role in power equipment. Pin insulators show good use value in the power industry and can effectively protect large electrical equipment from damage. Pin insulators need to withstand great pressure and bearing capacity at high altitudes, and need to withstand a certain load. Pin insulators have to withstand wind and rain outdoors, and need to withstand rain, so the application of pin insulators must ensure their quality and good performance. Pin insulators that do not meet the requirements should be replaced in a timely manner to avoid affecting the normal power supply of the line and causing a certain degree of impact on users.

[0003] At present, the main methods of replacing pin insulators on distribution network lines are power outage or live working with live working vehicles. At present, it is difficult to carry out such work projects with ground potential working methods. It is necessary to modify the fastener structure to effectively carry out the work of replacing pin insulators at ground potential. In the work of dealing with emergency defects such as wire flying and insulator falling off, many sites cannot be handled by ground potential, which has a great impact on the safe operation and handling efficiency of the line.

[0004] Due to the special structure of the pin insulator, the ground potential operation method can easily cause a single-phase ground short circuit, which poses a considerable hidden danger to the operation and work safety of the operators. Therefore, it is necessary to manufacture an effective wire winding device or other device that is convenient for fixing the wire to complete the ground potential operation, ensure the safety of the operation and further improve the work efficiency.

The clamping component 101 in the fixing unit 100 cooperates with the upper fixing component 102 and the lower fixing component 103 to achieve a firm clamping of the insulator; the clamping mechanism 201 in the operating unit 200 is responsible for clamping the conductor onto the insulator, and the adjusting mechanism 202 allows the operator to finely adjust the clamping force and position.

[0037] Specifically, the fixing unit 100 includes a clamping assembly 101, an upper fixing assembly 102 disposed on the top of the clamping assembly 101, and a lower fixing assembly 103 disposed at one end of the clamping assembly 101;

[0038] The operating unit 200 includes a pressing component 201 connected to the fixing unit 100 , and an adjusting component 202 connected to the pressing component 201 .

[0039] Furthermore, the clamping assembly 101 includes a first clamping block 101a and a second clamping block 101b that are symmetrically arranged. The first clamping block 101a and the second clamping block 101b are semicircular structures that are adapted to the neck groove of the insulator.

The middle hook 101c and the tail hook 101d are respectively engaged with the upper fixing component 102 and the lower fixing component 103.

[0041] Preferably, the first clamping block 101a and the second clamping block 101b are semicircular structures and are movably connected by axle pins. The operator fixes the first clamping block 101a and the second clamping block 101b to the neck groove of the porcelain bottle.

[0042] Furthermore, the upper fixing assembly 102 includes an upper tensioning block 102a and an upper clamping block 102b.

[0044] Furthermore, the clamping assembly 201 includes a clamping arm 201a and a wire pressing block 201b. The clamping arm 201a is designed to be arc-shaped, with a bolt hole 201c in the middle. The wire pressing block 201b is fixedly connected to the clamping arm 201a, and the part thereof in contact with the wire is an arc-shaped structure.

[0045] Preferably, a U-shaped groove is provided at the rear end of the clamping arm 201a, which is connected through the upper clamping block 102a and the upper pull ring 203, one end of the upper clamping block 102b is linked to the upper tensioning block 102a through an axle pin, and the other end of the upper tensioning block 102a is clamped with the hook in the middle position of the first clamping block 101a. When the operator operates the upper pull ring 203, the upper clamping block 102b can be controlled to drive the upper tensioning block 102a, thereby realizing the clamping or opening of one end of the upper tensioning block 102a with the middle hook 101c of the first clamping block 101a.

[0046] Furthermore, one end of the clamping arm 201a is movably connected to the first clamping block 101a via an axle pin, and a U-shaped groove 201d is provided at one end of the clamping arm 201a, and the U-shaped groove 201d is movably connected to the upper clamping block 102b.

[0047] Furthermore, the adjustment assembly 202 includes an upper adjustment screw 202a threadedly connected to the clamping arm 201a, and a lower adjustment bolt 202b connected to the lower clamping block 103b and the lower tensioning block 103a.

[0048] Preferably, the middle position of the second clamping block 101b is movably connected to the clamping arm 201a by an axle pin. The clamping arm 201a is designed in an arc shape to meet the installation requirements of the porcelain bottle position. A bolt hole is provided in the middle of the clamping arm 201a, and the upper adjusting screw 202a is threadedly connected to the bolt hole. The bottom end of the upper adjusting screw 202a is fixedly connected to the wire pressing block 201b. The contact part of the wire pressing block 201b with the wire is in an arc structure so as to crimp the wire to the corresponding position of the porcelain bottle. The wire and the porcelain bottle can be fixed by controlling the up and down position of the upper adjusting screw 202a.

[0049] Furthermore, the operating unit 200 further includes an upper pull ring 203 fixedly connected to one end of the upper pressing block 102b, and a lower pull ring 204 fixedly connected to one end of the lower pressing block 103b;

[0050] The upper pull ring 203 and the lower pull ring 204 are both annular structures, and the inner diameters thereof are larger than the outer diameters of the upper pressing block 102b and the lower pressing block 103b.

[0051] Preferably, by pulling the lower pull ring 204, the moving stroke of the lower tensioning block 6 and the clamping block 8 can be changed, and the size of the lower part can be changed so that the component can hold the umbrella skirt of the insulator and be fixed to the upper part of the insulator, and the wire can be pressed into the lower end of the clamping arm 201a. Then, by pulling the upper pull ring 203, the stroke of the upper tensioning block 102a and the upper clamping block 102b can be changed, and the upper adjusting screw 202a can be adjusted to change the stroke of the wire pressing block 201b and the degree of clamping the wire. Finally, the fastener can fix the wire and complete the action of binding the wire of the straight rod insulator.

[0052] Furthermore, the first clamping block 101a and the second clamping block 101b are movably connected through an axle pin to form an openable and closable semicircular structure; the upper adjusting screw 202a forms a threaded fit with the bolt hole 201c of the clamping arm 201a, the bottom end of the upper adjusting screw 202a is fixedly connected to the wire pressing block 201b, and the lower adjusting bolt 202b passes through the lower clamping block 103b and is connected to the lower tensioning block 103a.

[0053] It should be noted that the first clamping block 101a and the second clamping block 101b are semicircular structures and are movably connected by axle pins. The operator fixes the first clamping block 101a and the second clamping block 101b to the neck groove of the porcelain bottle. The other end of the first clamping block 101a is a hook structure, so that it can be clamped with one end of the lower tensioning block 103a through the axle pin; the other end of the second clamping block 101b is connected with the lower clamping block 103b by an axle pin. The lower clamping block 103b is an L-shaped structure as a whole, and the tail is connected to the lower pull ring 204. At the same time, the middle of the lower clamping block 103b is connected to the lower tensioning block 103a through the lower adjusting bolt 202b. When the operator operates the lower pull ring 204, the lower clamping block 103b can be controlled to drive the lower tensioning block 103a, so as to realize the clamping or opening of one end of the lower tensioning block 103a with the hook 101d at the tail end of the second clamping block 101b.

[0054] When in use, initial preparation and precise positioning on the insulator. The operator first sends the device to the target insulator position through the insulating rod. Then, by manipulating the lower pull ring 204, the first clamping block 101a and the second clamping block 101b of the clamping assembly 101 are opened. Align the opened clamping assembly 101 with the neck of the insulator, and operate the lower pull ring again to close the first clamping block 101a and the second clamping block 101b, thereby achieving preliminary fixation of the insulator. At this time, the lower tensioning block 103a of the lower fixing assembly 103 will be engaged with the tail end hook 101d of the second clamping block 101b. The first clamping block 101a and the second clamping block 101b are semicircular structures and are movably connected by an axle pin. The operator carefully aligns the first clamping block 101a and the second clamping block 101b with the neck groove of the porcelain bottle to prepare for subsequent fixation.

[0055] Achieve quick preliminary fixation on the insulator. The operator controls the lower clamping block 103b by pulling the lower pull ring 204. The lower clamping block 103b is an L-shaped structure. By driving the lower tensioning block 103a, the end of the lower tensioning block 103a is clamped with the tail hook 101d provided at one end of the second clamping block 101b. The first clamping block 101a and the second clamping block 101b can be tightly fixed at the neck position of the porcelain bottle to complete the preliminary fixation. At the same time, the middle of the lower clamping block 103b is connected to the lower tensioning block 103a through the lower adjustment bolt 202b, allowing further adjustment.

[0056] Prepare for positioning and clamping the wire. After the initial fixation, the operator pays attention to the upper fixing assembly 102. The clamping arm 201a is designed in an arc shape and is movably connected to the middle position of the first clamping block 101a through an axle pin. The U-shaped groove at the tail end of the clamping arm 201a is connected through the upper clamping block 102b and the upper pull ring 203. One end of the upper clamping block 102b is connected to the upper tensioning block 102a through an axle pin, and the other end of the upper tensioning block 102a is clamped with the hook in the middle position of the first clamping block 101a.

[0057] Precise positioning and preliminary fixation of the conductor. After fixing the device, the operator adjusts the position of the clamping arm 201a by controlling the upper pull ring 203. The clamping arm 201a can be flexibly swung to adapt to different conductor positions through the hinged design with the first clamping block 101a and the upper clamping block 102b. After swinging the clamping arm 201a to the appropriate position, the wire pressing block 201b contacts the conductor. The part of the wire pressing block 201b that contacts the conductor is an arc-shaped structure, which is convenient for crimping the conductor to the corresponding position of the porcelain bottle. Achieve preliminary positioning of the conductor.

[0058] Precise control of the wire clamping force. After the wire is initially positioned, the operator changes the stroke of the upper tension block 102a and the upper clamping block 102b by pulling the upper pull ring 203 to adjust the upper structure. Adjust the upper adjusting screw 202a to control the clamping force of the wire pressing block 201b on the wire. The upper adjusting screw 202a forms a threaded fit with the bolt hole 201c of the clamping arm 201a. The position and pressure of the wire pressing block 201b can be finely adjusted by rotating the upper adjusting screw 202a. The operator can change the moving stroke of the lower tension block 103a and the lower clamping block 103b by pulling the lower pull ring 204, change the size of the lower part, and enable the components to firmly hold the umbrella skirt of the insulator and be fixed to the upper part of the insulator. Then change the stroke of the upper tension block 102a and the upper clamping block 102b by pulling the upper pull ring 203. The positions of the lower pressing block 103b and the lower tensioning block 103a are fine-tuned by adjusting the lower adjusting bolt 202b-1, so as to accurately adjust the tightness of the lower fixing assembly 103.

[0059] Replace the insulator while keeping the conductor fixed. After the device is firmly installed, the operator can safely remove the original insulator fixing device. Since the conductor is firmly supported by the new device, the old insulator can be removed and the new insulator can be installed without affecting the position of the conductor. During the entire process, the conductor is always kept in a safe and stable position. After the new insulator is installed and the conductor is fixed, the operator removes the device in the reverse order of installation. First, loosen the upper adjustment screw 202a to release the pressure on the conductor. Then operate the upper pull ring 203 to move the clamping arm 201a away from the conductor. Finally, open the clamping assembly 101 through the lower pull ring 204 and carefully remove the entire device from the insulator.

[0060] In summary, the clamping component in the fixing unit adopts an openable and closable semicircular structure, and cooperates with the elastic clamping mechanism of the upper and lower fixing components, so that the device can be clamped on the insulator quickly and firmly, greatly improving the installation efficiency. The clamping arm in the operating unit realizes flexible swinging movement through the multi-point hinge design with the clamping component and the upper clamping block, so that the wire pressing block can accurately position and clamp the wire. At the same time, the threaded matching structure of the upper and lower adjustment components allows the operator to make fine adjustments to ensure precise control of the clamping force. The entire device can complete the insulator replacement operation safely and efficiently under the power supply, and it also significantly reduces the difficulty of operation and reduces the operation time. The compact design of the device and the use of a single operating rod effectively control the length of the component, minimize the risk of grounding faults, and further improve the safety of the operation.
