Abstract

The invention discloses a novel overhead line system hanging device, solving the problems of complex structure, inconvenience in mounting and maintenance and influence on urban landscape in the prior art. The novel overhead line system hanging device comprises an upright column and a wrist arm connected with the upright column; the wrist arm is connected with a positioning support movably connected with a positioning pipe, such that an included angle between the positioning pipe and ground can be regulated; the positioning pipe is provided with a positioner which can move per se and is used for fixing a contact wire in thermal expansion and cold contracting of the contact wire. By the technical solution, the problems of the prior art can be well solved.

Description

technical field [0001] The invention belongs to the field of urban rail transit equipment, and in particular relates to a novel catenary suspension device. Background technique [0002] The catenary is a high-voltage transmission line erected in a "zigzag" shape along the sky above the rails in the electrified railway for pantographs to take current. The catenary is the main frame of the railway electrification project, and it is a special form of transmission line erected along the railway line to supply power to the electric locomotive. At present, the suspension types of catenary on the market can be divided into simple contact suspension and chain contact suspension. Generally, a simple suspension form is selected for the catenary of a tram, because the simple contact suspension can ensure better current reception under the condition of determining the running speed of the tram. However, with the extensive application of trams in cities, the disadvantages of its compli...
