Description

Technical Field

[0001] The invention relates to the field of power supply cables, and in particular to a cable spacing structure for a non-climbing type anti-voltage line stranded wire. Background Art

[0002] The power line spacing structure is an important equipment for overhead transmission lines. It keeps the split conductors in a certain geometric shape to prevent the conductors from whipping and entangled with each other under the influence of wind and other factors. It reduces the vibration of the conductors, reduces the fatigue damage of the conductors caused by breeze vibration and other factors, and prolongs the service life of the conductors. It is usually composed of a frame, a wire clamp and connecting parts. The wire clamp is used to clamp the conductors, the frame provides support and maintains the spacing, and the connecting parts connect the spacer rods to the conductors.

[0003] When installing the structure between power lines, it is necessary to prepare before installation, check whether the spacers and supporting parts are complete and intact, and whether there is any damage or deformation. Prepare the tools required for installation, such as wrenches, screwdrivers, hangers, etc. Confirm the installation position, which is generally evenly arranged in the middle of the span according to the line design requirements. Pay attention to safety during installation, and wear protective equipment such as safety helmets and safety belts. Install strictly in accordance with the installation instructions and operating procedures, and do not change the installation method at will. After installation, the installation quality must be inspected and accepted to ensure that the spacers can function normally.

[0004] The power line spacing structure is generally installed manually, and the installation process mainly relies on manual operation, which is relatively slow. Especially in long-distance lines or large-scale projects, the installation progress will be greatly limited and the efficiency is low. At the same time, when installing manually, workers need to work at high altitudes and face various safety risks such as falling and electric shock. Even if safety protection equipment is equipped, the danger cannot be completely eliminated. Long-term high-altitude work can easily cause worker fatigue and increase the possibility of safety accidents. Therefore, a cable spacing structure of a non-climbing anti-voltage line strand is provided. Summary of the invention

After insertion, the cable and the hanging barrel are in a parallel structure, and the inner wall of the hanging barrel is provided with an insulating rubber pad.

[0013] Furthermore, the hanging assembly includes a box body, an upper limit plate and a lower limit plate;

When the height of the cable hanging mechanism is higher than the height of two adjacent cables, the insulating long rod is rotated to make the horizontal spacing cylinder on the spacing component perpendicular to the cable, and the hanging cylinder on the spacing component is parallel to the cable. The insulating long rod is pulled vertically downward, and the insulating long rod drives the top upper bracket to move vertically downward. During the movement, the upper bracket is sent into the upper limit plate, and the box is pressed down by the upper bracket, and then the hanging cylinder is driven to move vertically downward, and the threading notch on the hanging cylinder is passed through the cable, and the cable is sent into the hanging cylinder, and the hanging cylinders at both ends of the spacing component 1 are hung between the two adjacent cables, thereby supporting the adjacent cables and preventing the two adjacent cables from whipping and entanglement with each other.

[0068] Working principle:

[0069] When installing the cable spacing structure and the cables, the spacing component 1, the hanging component 2 and the spacing frame installation component 3 are mainly used in coordination with each other, wherein the spacing component 1 and the hanging component 2 are integrally connected to form a cable hanging mechanism, and the spacing frame installation component 3 cooperates with the spacing component 1 and the hanging component 2 to form a cable hanging mechanism;

[0070] When the cable hanging mechanism is hung on two adjacent cables, first, the upper bracket 32 ​​on the spacer mounting assembly 3 is in the same direction as the hole position of the socket 24 on the box body 21, so that the upper bracket 32 ​​passes through the socket 24 on the box body 21, so that the upper bracket 32 ​​is set above the box body 21, and the lower bracket 33 is set in the box body 31, and then the insulating long rod 31 on the spacer mounting assembly is rotated, and the rotation angle is 90 degrees. The insulating long rod 31 drives the upper bracket 32 ​​and the lower bracket 33 to rotate 90 degrees synchronously. When the upper bracket 32 ​​and the lower bracket 33 are rotated 90 degrees, the upper bracket 32 ​​and the lower bracket 33 are in a vertical state with the socket 24, and then the lower bracket 33 on the spacer mounting assembly 3 is inserted into the lower limit plate 23 inside the box body 21, and the lower bracket 33 is limited by the lower limit plate 23 to prevent the lower bracket 33 from continuing to rotate. The frame 33 connects the spacing component 1 and the hanging component 2 to form a cable hanging mechanism that lifts it up. When the height of the cable hanging mechanism is higher than the height of two adjacent cables, the insulating long rod 31 is rotated to make the horizontal spacing cylinder 13 on the spacing component 1 perpendicular to the cable, and the hanging cylinder 11 on the spacing component 1 is parallel to the cable. The insulating long rod 31 is pulled vertically downward, and the insulating long rod 31 drives the top upper bracket 32 ​​to move vertically downward. During the movement, the upper bracket 32 ​​is sent into the upper limit plate 22, and the box 21 is pressed down by the upper bracket 32, and then the hanging cylinder 11 is driven to move vertically downward, and the threading notch 14 on the hanging cylinder 11 is passed through the cable, and the cable is sent into the hanging cylinder 11, and the hanging cylinders 1 at both ends of the spacing component 1 are hung between the two adjacent cables, thereby supporting the adjacent cables and preventing the two adjacent cables from whipping and entanglement with each other. After completing the above operations, first push the insulating long rod 31 vertically upward to disengage the upper bracket 32 ​​on the insulating long rod 31 from the upper limit plate 22, and then rotate the insulating long rod 31 90 degrees to make the upper bracket 32 ​​and the socket 24 on the box 31 in the same direction, so that the bracket 32 ​​passes through the socket 24, and the spacer mounting assembly 3 is disengaged from the hanging assembly to complete the installation between the cable spacing structure and the cables. When installing manually, workers do not need to work at high altitudes to prevent various safety risks such as falling and electric shock.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
