Abstract

The invention relates to a tool for manufacturing a 0.4kV-66kV power line stay wire. According to the structure of the tool, one end of a hammer handle is connected with a hammerhead, the other end of the hammer handle is connected with one end of a chain, the other end of the chain is connected with an oval lantern ring, the width of the oval lantern ring is matched with the diameter of the stay wire, and the length of the oval lantern ring is equal to the sum of the width of a wedge-shaped wire clamp clapper and the diameter of the stay wire. Through the structures of the oval lantern ring, the hammerhead and the like, the problem that the two ends and the arc-shaped top of a stranded galvanized steel wire make untight contact with the clapper is solved. Labor and time are saved during manufacturing, and process attractiveness accords with regulations.

Description

technical field [0001] The invention relates to a power line auxiliary tool, in particular to a time-saving and labor-saving tool for making 0.4kV-66kV power line pull wires. Background technique [0002] With the vigorous development of electric power enterprises and the gradual upgrading of rural power grid transformation, the materials for the 0.4kV--66kV power line guy wires are gradually transformed from the original No. 8-No. 10 galvanized iron wires to galvanized steel strand guy wires. The specification of the pull wire is determined according to the design requirements, but it shall not be less than the minimum section specified in the regulations: 25mm for the galvanized steel strand 2 , The pull wire is usually divided into upper, middle, and lower parts. The upper part is connected to the pole and is called the upper handle. The lower pull wire includes the pull wire ring and the pull wire rod are called the lower handle. The connecting part of the upper handleb...
