Electrified railway contact line counter weight device

Abstract

The invention relates to an electrified railway contact line counter weight device. By reducing tension of contact lines, vertically upward component force of the contact lines can be reduced effectively, but sag of the contact lines is increased, so that the technical standard of circuits is reduced, the potential safety hazard is caused, and certain limitations exist. The electrified railway contact line counter weight device comprises a contact line counter weight box in the shape of H with the lower half part expanded, and counter weights are placed in the middle of the box body. The upper end of the contact line counter weight box is dynamically suspended on a carrier cable and can move up and down. Oppositely-penetrating bolts arranged on the top of a U-shaped clamp can prevent the contact line counter weight box from falling off from the carrier cable, and two feet of the lower end of the contact line counter weight box are fixed to the contact lines through contact line counter weight line clamps. According to the electrified railway contact line counter weight device, the concept is ingenious, installation is convenient, and quantity can be set and the number of the counter weights can be increased and decreased according to actual needs; the problem that because curve force is oversized, the contact lines are raised is solved; the high technical standard requirement of an electrified railway contact net is guaranteed; and contact line hard spots are not formed.

Description

technical field [0001] The invention belongs to the technical field of electrified railway catenary components, and in particular relates to a counterweight device for electrified railway contact lines. Background technique [0002] Catenary is a special form of transmission line erected along the railway line to supply power to electric locomotives, mainly including contact wires and catenary cables. The railway line includes straight and curved sections, and the minimum curve radius of the curved section can reach 300 meters under difficult circumstances. The catenary clues are arranged in a zigzag shape when arranged in a curved section, and in a zigzag shape when arranged in a straight section. At the pillar point, the horizontal component force is generated due to the change of the direction of the clue (the horizontal component force is called the curve force in the curve segment, and the zigzag force in the straight segment). Within the effective working range of th...
