Aluminum alloy profile sleeve connecting device

Abstract

The invention discloses an aluminum alloy profile sleeve connecting device. The aluminum alloy profile sleeve connecting device is formed by fixedly connecting two sleeves; the sleeves are composed of two semicircle annular main hoops and two semicircle annular auxiliary hoops; the lower end of each sleeve is provided with double vertical plates with a connection hole; the double vertical plates on one of the sleeves are clamped on the outer sides of the double vertical plates on the other sleeve, and the vertical plates are connected through a fastener; the two sleeves are fixed to a horizontal cantilever and an inclined cantilever correspondingly; axial bosses are arranged on the inner annular surfaces of circular rings of the main hoops and the inner annular surfaces of circular rings of the auxiliary hoops; and the main hoops and the auxiliary hoops are all made of aluminum alloy profiles. Sleeve bases made of the aluminum alloy profiles are small in size and low in weight; the production and manufacturing process of the main hoops and the auxiliary hoops is greatly simplified, and the production efficiency is improved; and moreover, the phenomenon that parts are rusted due to rainwater erosion is completely eradicated. Meanwhile, installation is convenient, the construction and installation cost is reduced.

Description

technical field [0001] The invention relates to an electrified railway catenary erection equipment, in particular to an aluminum alloy profile bushing connector. Background technique [0002] At present, steel precision castings or aluminum alloy precision castings are generally used to connect the flat arm and inclined arm of the electrified railway catenary. The weight of the steel precision casting increases the load of the catenary, and it is easy to rust and corrode. Although precision castings are light in weight, their manufacture is cumbersome and bulky. There are many control points in the manufacturing process, and the productivity is low. There are many fasteners that need to be fastened during installation and construction, which affects the construction progress. With the development of electrified railways With rapid development, the construction requirements of easy installation, superior performance, and cost reduction are particularly important, but the abov...
