The invention provides a pre-tightening bolt-free positioning wire clamp for a railway overhead line system, belongs to the technical field of flexible suspension positioning equipment of an electrified railway overhead line system, and aims to solve the problems that bolts of an existing positioning wire clamp for the overhead line system are loosened in actual operation, and the structural design needs to be further improved. A positioning wire clamp main body is formed by inserting a positioning pin in the middle of a left half C-shaped positioning wire clamp and a right half C-shaped positioning wire clamp with holes and connecting the left half C-shaped positioning wire clamp and the right half C-shaped positioning wire clamp with holes into a whole, and then an elastic U-shaped wire clamp hoop is sleeved outside the wire clamp main body of the left half C-shaped positioning wire clamp and the right half C-shaped positioning wire clamp with holes; a positioning fixing pin is inserted into the through hole of the hoop, and is inserted, locked and fixed by a split pin; and wire clamping nozzles of the left half C-shaped positioning wire clamp and the right half C-shaped positioning wire clamp with holes are connected with a contact wire in a clamping manner. The whole structure is novel and practical, and is suitable for erecting positioning contact lines for the electrified railway overhead line system.
