Abstract
The utility model discloses novel bushing double-shackles, which consist of a U-shaped bolt (1) and a body (2); the inner end of the body (2) is a circular arc; and the outer end of the body (2) is provided with the double shackles (4); the U-shaped bolt (1) penetrates through a connecting hole on the body (2) and then is connected together with the body (2) through a nut (3). The novel bushing double-shackles are used for connecting a flat wrist arm and an incline wrist arm of an electrified railway contact net, has simple and novel structure, is convenient to mount and maintain, has high safety and reliability, and is suitable for the demands of high speed developing on the electrified railways.
Description
Technical field
The utility model relates to a kind of new casing ears, belongs to high-speed electric railway Catenary Fittings manufacturing technology field.
Background technology
The high-speed electric railway contact system uses the Aluminium alloy arm for electric railway contact net as supporting part system at present, the preceence of Aluminium alloy arm for electric railway contact net as supporting part is light weight, antiseptic property is good, safety, reliability height, installation and easy to maintenance, connect attaching parts flat, oblique wrist and arm at present and adopt aluminum alloy sleeve base structure, combine with two identical sleeve pipe monaurals, complex structure, safe reliability is low, the installation and maintenance inconvenience can not be suitable for the growth requirement of high-speed electric railway fully.
Summary of the invention
The technical matters that the utility model solves: design a kind of new casing ears, be used to connect that the high-speed electric railway contact system is flat, oblique wrist and arm, novelty simple in structure, installation and maintenance are convenient, and the safe reliability height adapts to the demand of electrified railway high speed development.
Technical solution of the present utility model: a kind of new casing ears be made of U-bolt (1) and body (2), and the inner of body (2) are arc surface that the outer end has ears (4); U-bolt (1) links together by nut (3) and body (2) after passing connecting bore on the body (2).
Described U-bolt (1) segment of curve is the semicircle segmental arc, and the inner of body (2) is the semicircle cambered surface.
Described body (2) adopts the metal paattern precision casting process to make.
The utility model novelty compared with prior art simple in structure, installation and maintenance are convenient, safe reliability height, the demand of adaptation electrified railway high speed development.
Description of drawings
Fig. 1 is a structural front view of the present utility model,
Fig. 2 is a structure left 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 new casing ears are made of U-bolt 1 and body 2, and U-bolt 1 segment of curve is the semicircle segmental arc, and the inner of body 2 is the semicircle cambered surface, and the outer end of body 2 has ears 4; U-bolt 1 links together by nut 3 and body 2 after passing connecting bore on the body 2.Described body 2 adopts the metal paattern precision casting process to make.
During use, on Horizontal Cantilever 6, make Horizontal Cantilever be close to body 2 inner arc surfaces body 2 anchor ears, be with U-bolt 1 then and link together, bushing double eye is connected with Horizontal Cantilever to reach fixes by nut 3 and body 2.Will and the monaural of bushing double eye bonded assembly part place between the ears 4, put on pin 5, confirming under the situation that monaural can freely rotate, on pin 5, put on spring cotter and remove to bend and get final product.
