Description

Technical Field

[0001] The utility model relates to a high-voltage power line spanning frame for overhead line relocation construction, belonging to the technical field of high-voltage power line spanning. Background Art

[0002] Power lines are used to transmit electrical energy and are a crucial component of the power supply system. They are primarily responsible for the transmission and distribution of electrical energy. They require safety, reliability, and ease of operation. They can be categorized as overhead lines or cable lines. The majority of high-voltage power lines are overhead. During overhead line construction, when encountering obstacles such as railways, roads, and power lines, spanning structures must be installed between the overhead line and the structures to prevent obstruction.

[0003] The Chinese patent with authorization announcement number CN210867001U is named as a high-voltage power line crossing frame for overhead line relocation construction, which includes a horizontally arranged base plate and also includes: a vertical plate arranged at the center of the base plate and extending vertically upward, the four corners of the base plate are provided with fixed threaded holes that penetrate the wall thickness of the base plate, the axial direction of the fixed threaded holes is perpendicular to the base plate, and a mounting groove is provided in the vertical plate, the extension direction of the mounting groove is parallel to the length direction of the vertical plate, and a through hole connected to the mounting groove is provided vertically downward at one end of the top surface of the vertical plate.
