Abstract

The invention discloses a positioning stand column for an inclined cantilever. The positioning stand column comprises a positioning pipe (1) and a support (2). The support (2) comprises an insertion portion (2-1) inserted into one end of the positioning pipe (1), a transition table (2-2) is arranged on the insertion portion (2-1), a fixing plate (2-3) for supporting the inclined cantilever is arranged on the transition table (2-2), a connecting hole (2-31) is formed in the fixing plate (2-3), a U-shaped bolt (3) connected to the interior of the connecting hole (2-31) to fix the inclined cantilever is arranged on the fixing plate (2-3). A groove (2-32) for containing the inclined cantilever is formed in the fixing plate (2-3). A fixedly-connected rivet (4) is arranged on the support (2) and the positioning pipe (1). By adopting the structure, the numbers of positioning rings, positioning pipes and fasteners are decreased, on-site construction and installation and follow-up maintenance are convenient, the product safety is improved, and potential operational risk is reduced.

Description

technical field [0001] The invention relates to the technical field of catenary equipment for electrified railways, in particular to a positioning column for an inclined arm. Background technique [0002] In the electrified railway catenary system, the positioning support plays the role of connecting the positioning pipe and the positioner, and is an important connecting part in the positioning device. In the catenary system that has been built and operated in my country, the traditional way is used to connect under the standard side limit (the distance between the side of the column and the center of the line). The three parts are connected to each other. One is that in the case of a small side boundary, if the traditional connection method is used, the connection space cannot accommodate the above three parts, and the connection parts are slightly cumbersome and the structure is not compact. In response to these problems, it is proposed to integrate and optimize the funct...
