Problems solved by technology

Although this connection method does not cause a hard point on the contact wire, the bow-shaped wrist arm is deformed during the use of the line due to the excessive torque on the bow-shaped wrist arm, so this connection method cannot meet the requirements of the line. Requirements

Abstract

A low clearance single track tunnel contact wire positioning device comprises an arched base, a connecting double lug, a rotating double lug, an elastic insulated limiting positioner and a positioningwire clip; the arched base is fixed on the wall of a tunnel through a bolt; the connecting double lug is fixed at the front end of the arched base through a bolt pair; the rotating double lug is hinged to the front end of the connecting double lug through a pin shaft; the rear end of the elastic insulated limiting positioner is a bent section; the end part of the bent section is hinged between lower lugs at the front end of the rotating double lug through a bolt pin I; an elastic pull rod is mounted at the middle part of the bent section; the upper end of the elastic pull rod is hinged between upper lugs at the front end of the rotating double lug through a bolt pin II; and the positioning wire clip is fixed under the front end of the elastic insulated limiting positioner. According to the low clearance single track tunnel contact wire positioning device, shortcomings in the prior art are eliminated, the elastic uniformity of an overhead line system is improved, the current collectingquality of a pantograph type current collector is improved, and therefore, the safety running of a locomotive is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of catenary systems for electrified railways, and in particular relates to a positioning device for contact lines of low clearance single-track tunnels. Background technique [0002] At present, the suspension of the contact line in the electrified low-clearance single-track tunnel mostly uses horizontal suspension and a bow-shaped single-support wrist-arm structure, and the line running speed is below 120km / h. With the development of my country's electrified railway, the running speed of the train puts forward higher requirements for the catenary system in the low headroom single-track tunnel. The contact line in the horizontal suspension device is connected and fixed by the insulating locator. During the actual operation of the line, it is found that the insulating locator concentrates all its own weight (about 9.5kg) on ​​the contact line at the contact line positioning point, forming a negative impact on...
