Description

Technical Field

[0001] The utility model relates to the technical field of electric power facilities, in particular to a high-strength cross arm assembly for supporting electric power lines. Background Art

[0002] Power line crossarms are transverse members used to support transmission lines in power systems. They are usually installed on power towers to support power conductors, maintain conductor spacing, and maintain conductor tension. Power line crossarms are generally made of high-quality steel or aluminum alloy, and have sufficient strength and rigidity to withstand the weight and wind load of transmission lines. The main functions of power line crossarms include: 1. Supporting conductors: Power line crossarms are fixed on power towers to support the conductors on the transmission lines, enabling them to hang in the air and transmit electricity. 2. Maintaining conductor spacing: Power line crossarms are installed on power towers to fix the position and spacing of conductors according to design requirements, ensure a safe distance between conductors, and prevent faults such as phase-to-phase short circuits. 3. Maintaining conductor tension: By fixing the power line crossarms and correctly adjusting the tension, the appropriate tension of the conductor can be maintained, and the position and shape of the conductor can be kept stable under various conditions. Power line crossarms play an important supporting and stabilizing role in the power system and play a key role in the safe operation of transmission lines. Their manufacture and installation need to comply with strict standards and specifications to ensure the reliability and safety of the power system.

[0003] A high-strength crossarm assembly for supporting power lines is disclosed in the Chinese utility model patent application disclosure CN214996545U. Although the utility model has a sliding block located inside a sliding groove and is in a sliding fit, so that the angle of the crossarm can be easily adjusted, when adjusting the angle of the crossarm, the bolts need to be unscrewed. During the unscrewing process, the staff needs to use a wrench to unscrew it little by little, which is a rather cumbersome process and has the disadvantage of poor convenience.

At the same time, through the cooperation of the worm and the worm wheel, it has self-locking properties. The device can adjust the horizontal angle of the crossarm body by turning the rotating disk, and can be quickly and conveniently adjusted during subsequent construction or line changes.
