Catenary dropper capable of being rapidly constructed and construction method of catenary dropper

The invention discloses an overhead line system dropper capable of being quickly constructed and a construction method of the overhead line system dropper, relates to the technical field of overhead line system droppers, and solves the problems that when the dropper is installed, the end part of the dropper is generally bent, and then the bent end part of the dropper is fixed by using a metal piece, although the fixing mode is firm, the operation difficulty is relatively high during installation, and the installation cost is relatively high. The device comprises a dropper steel rope, the two ends of the dropper steel rope are bent in a U shape, the outer sides of the ends of the dropper steel rope are sleeved with end locking blocks, annular clamping grooves are formed in the outer surfaces of the two ends of the dropper steel rope, and the same sides of the two end locking blocks are provided with quick locking mechanisms and connected through the quick locking mechanisms. According to the invention, the dro
