Abstract
An aluminum alloy inclined cantilever comprises an inclined cantilever pipe 1 and a single-lug connecting terminal 2, wherein the single-lug connecting terminal 2 is fixed at one end of the inclined cantilever pipe 1. The single-lug connecting terminal 2 is connected with external components, for example a sleeve with two lugs, through the single lug at the end, thereby realizing supporting suspension and positioning for a catenary system. The aluminum alloy inclined cantilever is stable and simple in structure, and high in joint strength and reliability.
Description
Technical field
The utility model relates to a kind of aluminum alloy oblique wrist and arm, belongs to electrification railway contact net Parts manufacturing technology field.
Background technology
Electric railway railway line for passenger traffic contact system adopts the Aluminium alloy arm for electric railway contact net as supporting part system in a large number, oblique wrist and arm is as the strength member in the bracket system underwork, need be on specification, other parts of aspect such as material, performance, interface mode and bracket system are suitable, and will guarantee its safety performance simply simultaneously requiring to install.Existing oblique wrist and arm can not satisfy the requirement of electrified railway high speed development.
Summary of the invention
The technical matters that the utility model solves: design a kind of aluminum alloy oblique wrist and arm, its oblique wrist and arm pipe is connected the termination captive joint with monaural, and connect to form underwork by bushing double eye and Horizontal Cantilever, in the bracket device, finish supported and suspended and positioning function to contact net system, simple and stable structure, the Joint strenght height, good reliability.
Technical solution of the present utility model: a kind of aluminum alloy oblique wrist and arm, comprise oblique wrist and arm pipe (1),
One end of described oblique wrist and arm pipe (1) is fixed with monaural and connects termination (2).
Described monaural connects termination (2) and is inserted in the oblique wrist and arm pipe (1), and by dowel pins (3) riveted and fixed.
Described monaural connects termination (2) and adopts cast steel or aluminium alloy casting to make, and oblique wrist and arm pipe (1) adopts aluminum alloy to make.
The utility model oblique wrist and arm pipe is connected the termination and adopts the dowel pins riveted and fixed with monaural, improved the part connection reliability, and monaural connects the termination and is connected simple and stable structure, Joint strenght height, good reliability with exterior part by end monaural head.
Description of drawings
Fig. 1 is a structural front view of the present utility model,
Fig. 2 is a structure birds-eye view of the present utility model.
The specific embodiment
1,2 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of aluminum alloy oblique wrist and arm is connected termination 2 by oblique wrist and arm pipe 1 and constitutes with monaural.Described monaural connects termination 2 and is inserted in the oblique wrist and arm pipe 1, and by dowel pins 3 right-angled crossing riveted and fixed, has improved the part Joint strenght.Described monaural connects termination 2 and adopts cast steel or aluminium alloy casting to make, and oblique wrist and arm pipe 1 adopts aluminum alloy to make.Monaural connects termination 2 and is connected by exterior parts such as end monaural head and bushing double eyes.
During use, oblique wrist and arm is not inserted in the matching hole of bracket insulator with an end that connects monaural, rotation oblique wrist and arm pipe is accurately located between the ears of monaural head that will connect monaural and bushing double eye, the inserting bolt pin, the hand-tight make-up nut penetrates spring cotter and breaks into two with one's hands, prevents nut loosening.
