Abstract

The invention discloses a cantilever type light overhead line system suspension system positioning device, which comprises a positioning connector, a rotary double-lug, a positioner, a positioning wire clamp and a U-shaped bolt. The upper end of the positioning connector is fixedly connected with a connecting base, and the U-shaped bolt is arranged opposite to the connecting base and connected tothe connecting base; the rotary double-lug is vertically hinged to the lower end of the positioning connector, one end of the positioner is horizontally hinged to the rotary double-lug, and the otherend of the positioner is fixedly connected with the positioning wire clamp. The device has the effects of electrical insulation and pull-out value fixation, the structural composition of the cantilever device can be simplified, the number of parts of the whole device is reduced, and installation and operation are more convenient; the electrified range is narrowed due to the electrical insulation function, and compared with a traditional direct-current 1500V flexible suspension system, the device is safer and more reliable.

Description

technical field [0001] The invention relates to the technical field of a positioning device for an urban rail transit catenary, in particular to a positioning device for a cantilever-type light-duty catenary suspension system. Background technique [0002] The positioning device used in the catenary system of urban rail transit is a key component of the catenary system. Its function is to pull the contact line out according to the design standard through the positioning line clamp, and fix the contact line at a certain position to ensure contact. The working surface of the line is parallel to the rail surface and bears the horizontal force of the contact line, ensuring that the catenary is always within the working range of the pantograph sliding plate, good current flow, and avoiding accidents caused by falling off the bow. [0003] At present, in my country's urban rail transit DC 1500V power supply system, the positioning device in the flexible suspension catenary mainly ...
