Problems solved by technology
[0003] When the current transmission tower is in use, after the asymmetrical fracture of the transmission line on the transmission tower, the transmission line will not only generate vertical loads on the transmission tower, but also generate horizontal loads, resulting in the rotation of the outrigger, making the distance between the two sections of the conductor change. If the wire is too short, the wire will fall and the wire is too low. Therefore, there is an urgent need for a self-resetting and repairable outrigger lifting transmission tower that uses hydraulic damping to solve the above problems.

The invention discloses a self-resetting maintenance extending arm ascending power transmission tower utilizing hydraulic damping, belongs to the technical field of power transmission towers. The self-resetting maintenance extending arm ascending power transmission tower utilizing hydraulic damping comprises a main tower, a low-hanging-point single rotating arm and a resettable torsion hydraulic damper are arranged on a main tower rotating shaft arranged at the upper end of the main tower, a resettable hydraulic power interface valve is arranged on the resettable torsion hydraulic damper, anda dustproof mechanism is also arranged on the resettable hydraulic power interface valve. According to the self-resetting maintenance extending arm ascending power transmission tower utilizing hydraulic damping, during normal use, the characteristic of the stable and durable structure is achieved, during accident condition, a good effect of slow and effective unloading is achieved, the power transmission tower is safer under the accident condition, the manufacturing cost of the power transmission tower for reducing the torsion effect is reduced, the capacity of the low-hanging-point single rotating arm under the support of external power and a safety device for preventing a wire from being too low are improved, and the convenience of installation and maintenance and the safety of the powertransmission tower under the accident condition are achieved.
Description
technical field [0001] The invention relates to the technical field of power transmission towers, in particular to a self-resetting and repairable boom-rising power transmission tower utilizing hydraulic damping. Background technique [0002] The transmission tower is the support point of the overhead line. One circuit is erected on the transmission tower, which is a single-circuit transmission tower, and two circuits are erected on the transmission tower, which is a double-circuit transmission tower. A single circuit refers to a circuit in which a load has one power supply; a double circuit refers to a circuit in which a load has two power supplies. Generally, enterprises with high reliability requirements for power supply, or important substations in the region, use double-circuit power supply, which can protect one of the power supplies from power failure, and the other power supply can continue to supply power, but for general power supply reliability requirements are no...
