Abstract
The utility model is the reinforced spring catch of a kind of transmission line, solves the problem that transmission line spring catch easily lost efficacy because of unreasonable structure.The utility model comprises U-shaped steel bar, and the end, two ends of U-shaped steel bar is connected with curved steel bar side by side with it respectively by connecting portion, and curved steel bar is provided with arc-shaped notch; Two curved steel bars are placed in the both sides of U-shaped steel bar, and U-shaped steel bar and two curved steel bars are positioned at same plane; The outside portion of two straight steel bars of U-shaped steel bar is fixed with thickening part.The utility model spring catch design science, rational in infrastructure, Yin Putong spring catch can be taken precautions against easily upwarded pressure, cause spring catch to be out of shape, wearing and tearing loses locking connection function, and fall the drawback of string, the further expansion of defect can be prevented or cause serious accident, be the reinforced spring catch of a kind of transmission line, there is very high promotional value.
Description
Technical field
The utility model relates to transmission line safe operation field, is specially the reinforced spring catch of a kind of transmission line.
Background technology
The common spring catch of transmission line, major part is arranged on for connecting cross-arm and wire insulation substring, due to shaft tower be subject to landform dipping and heaving time, at the shaft tower in low-lying location, wire is very easily subject to uplift force upwards, when wire pulls out, insulator string is in relaxed state, insulator string wind-force swing and uplift force extruding under, spring catch is very easily out of shape, spring catch also owing to repeatedly rubbing and abrasion deformation, finally can make spring catch lose locking effect, and causes falling string substantial equipment or power grid accident simultaneously.Therefore, the reinforced spring catch of development transmission line, can solve the threat that above-mentioned drawback is brought transmission line, thus guarantee the safe and stable operation of transmission line.
Summary of the invention
The purpose of this utility model is the problem easily lost efficacy because of unreasonable structure to solve transmission line spring catch, provides a kind of transmission line reinforced spring catch.
The utility model is achieved by the following technical solution:
The reinforced spring catch of a kind of transmission line, comprises U-shaped steel bar, and the end, two ends of U-shaped steel bar is connected with curved steel bar side by side with it respectively by connecting portion, curved steel bar is provided with the arc-shaped notch adapted with transmission line exterior contour; Two curved steel bars are placed in the both sides of U-shaped steel bar, and U-shaped steel bar and two curved steel bars are positioned at same plane; The outside portion of two straight steel bars of U-shaped steel bar is fixed with thickening part.
Further, described thickening part is made by the elastomeric material of steel, copper material or high elastic and strength, and thickness is 2mm.
Innovative point of the present utility model is the structure structure of spring catch, and the curved steel bar of the first U-shaped steel bar both sides, is provided with arc-shaped notch especially by transmission line, makes the locking effect of spring catch more firm like this; It two is that the outside portion of two straight steel bars of U-shaped steel bar is fixed with thickening part, and extra anti-extrusion effect can be played in thickening part, when thickening part be steel or copper material time, not only can increase the intensity of spring catch, the wear resistance of spring catch can also be strengthened; When thickening part is elastomeric material, the fixing that transmission line can be very tight is in spring catch, even if rubber has certain wearing and tearing, but transmission line still can under the effect of elastic rubber, and fixing is tightly in spring catch.Spring catch after improvement, avoids the drawback of the distortion that is in the past squeezed, and spring catch can be prevented to be out of shape and to cause falling string accident.
The utility model spring catch design science, rational in infrastructure, Yin Putong spring catch can be taken precautions against easily upwarded pressure, cause spring catch to be out of shape, wearing and tearing loses locking connection function, and fall the drawback of string, the further expansion of defect can be prevented or cause serious accident, be the reinforced spring catch of a kind of transmission line, there is very high promotional value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: the curved steel bar of 1-U section steel bar, 2-, 3-arc-shaped notch, 4-thickening part.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described:
As shown in Figure 1, the reinforced spring catch of a kind of transmission line, comprise U-shaped steel bar 1, the end, two ends of U-shaped steel bar 1 is connected with curved steel bar 2 side by side with it respectively by connecting portion, curved steel bar 2 is provided with the arc-shaped notch 3 adapted with transmission line exterior contour; Two curved steel bars 2 are placed in the both sides of U-shaped steel bar 1, and U-shaped steel bar 1 and two curved steel bars 2 are positioned at same plane; The outside portion of two straight steel bars of U-shaped steel bar 1 is fixed with thickening part 4.
During concrete enforcement, described thickening part 4 is made by the elastomeric material of steel, copper material or high elastic and strength, and thickness is 2mm.
