Description

technical field [0001] The invention relates to the technical field of power equipment maintenance tools, in particular to a pole mounting and fixing device for transmission line poles and towers. Background technique [0002] Transmission line towers are important equipment in high-voltage transmission lines. The inspection and maintenance of transmission line towers are important measures to ensure the safety of power transmission. In many cases, the maintenance of transmission line towers needs to be carried out under live conditions. Maintenance is carried out after the overall dismantling; and additional reinforcement is required on-site for the repaired parts, and then the repaired parts are removed for replacement and maintenance. Holding the pole can temporarily reinforce the transmission line tower to ensure that the transmission line tower can be used normally during the maintenance process. Therefore, before the maintenance and construction of the transmission lin...
