Abstract
The utility model discloses a stay rod crossarm. The stay rod crossarm is characterized in that: one side of a pole body is fixedly connected with a crossarm, the upper end of the pole body is provided with a pole body-connecting point, which is provided with a U-shaped bolt, a crossarm-connecting point is arranged on one end of the crossarm, and a stay rod is connected between the crossarm-connecting point and the U-shaped bolt. Because of the arrangement, i.e., the stay rod is added between the crossarm and the pole body, the deformation of the crossarm is greatly reduced; since the U-shaped bolt is adopted to connect the stay rod, the tightness of the stay rod can be flexibly adjusted, and the stability of the structure is enhanced. The stay rod crossarm is convenient to use, the maintenance efficiency is greatly increased, and the safety performance is greatly enhanced.
Description
Technical field
The utility model relates to a kind of electric power system overhead transmission that is used for and uses the shaft tower cross-arm, is a kind of brace cross-arm specifically.
Background technology
At present; It is the cantilever rigid attachment that electric power overhead send the most of cross-arm that adopts in the electrical engineering, and the statically determinate structure of this cross-arm has unsteadiness, and cross-arm can't the flexible elasticity; The cross-arm bottom stress is bigger; Not only waste of manpower but also expend time in of Construction and Maintenance causing construction to have inconvenience, and having potential safety hazard.
Summary of the invention
The purpose of the utility model just provides a kind of brace cross-arm.
To achieve these goals; The utility model is fixedly connected with cross-arm in a side of shaft, is provided with the shaft tie point in the upper end of shaft, on the shaft tie point, is provided with U-bolt; The cross-arm tie point is located at an end of cross-arm, is connected with brace between cross-arm tie point and the U-bolt.
Through above setting; The utility model has added brace between cross-arm and shaft, the distortion of cross-arm is significantly reduced, and brace adopts U-bolt to connect; But the elasticity of flexible brace; Strengthen stability of structure, the bending moment of cross-arm root has been changed into the pulling force of brace to a certain extent, thereby reduced the stress of cross-arm bottom.The utility model is easy to use, improves maintenance work efficient and security performance greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, shaft, 2, cross-arm, 3, the shaft tie point, 4, U-bolt, 5, the cross-arm tie point, 6, brace.
Embodiment
As shown in Figure 1; The utility model is fixedly connected with cross-arm 2 in a side of shaft 1, is provided with shaft tie point 3 in the upper end of shaft 1, on shaft tie point 3, is provided with U-bolt 4; Cross-arm tie point 5 is located at an end of cross-arm 2, is connected with brace 6 between cross-arm tie point 5 and the U-bolt 4.Through above setting; The utility model has added brace 6 between cross-arm 2 and shaft 1, the distortion of cross-arm 2 is significantly reduced, and brace 6 adopts U-bolt 4 to connect; But the elasticity of flexible brace 6; Strengthen stability of structure, the bending moment of cross-arm 2 roots has been changed into the pulling force of brace 6 to a certain extent, thereby reduced the stress of cross-arm 2 bottoms.
