Abstract

Disclosed is an aluminum alloy carrier cable seat. A horizontal circular pipe structure is arranged on the lower portion of a carrier cable seat body (1); an inclined cutting surface (3) is manufactured on an inner hole of the carrier cable seat body; a cup rim puller bolt (4) is screwed on the inner hole; a vertical circular tube structure is arranged on the upper portion of the carrier cable seat body; strip-shaped grooves (5) are manufactured on two sides of the stepped inner hole; a line supporting clamp (2) is in a 'T'-shaped structure; a carrier cable clamp (6) horizontally arranged is arranged on the upper portion of the line supporting clamp (2); a vertical cylinder (7) is arranged on the lower portion of the line supporting clamp (2); a box limit peg (8) is manufactured at the lower end of the vertical cylinder (7); and the vertical cylinder (7) on the lower portion of the line supporting clamp (2) is inserted inside the stepped inner hole on the upper portion of the carrier cable seat body (1) through the strip-shaped grooves (5) and rotates for a certain angle to position the boss limit peg (8) below a step to connect the line supporting clamp (2) onto the carrier cable seat body (1). The aluminum alloy carrier cable seat matching with an aluminum alloy waist arm system not only lightens contact net load, but also has simple and novel structure, is convenient in installation, debugging and maintenance, and meets the requirements of rapid development of electrification railroads.

Description

The aluminum alloy Messenger Wire base

Technical field

The utility model relates to a kind of aluminum alloy Messenger Wire base, belongs to contact nets in electrified railways 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 position fixing system in a large number, Messenger Wire base is as the important union piece that wherein is installed in bracket pipe upper support catenary, need be on specification, aspect such as material, performance, interface mode and other parts of Aluminium alloy arm for electric railway contact net as supporting part position fixing system are suitable.The general material that adopts of the Messenger Wire base of contact nets in electrified railways has two kinds at present: cast steel, forged steel.The steel Messenger Wire base has not only increased catenary load, and the structure more complicated, and the quantity of palpus binding bolt is more during installation, does not particularly match with the Aluminium alloy arm for electric railway contact net as supporting part system.Along with the high speed development of electrified railway, the construction requirement of simple installation, superior performance, cost-cutting is particularly important, and above-described two kinds of steel Messenger Wire bases are difficult to satisfy above-mentioned requirements.

Summary of the invention

The technical matters that the utility model solves: design a kind of aluminum alloy Messenger Wire base,, not only alleviated catenary load with the Aluminium alloy arm for electric railway contact net as supporting part system matches, and novelty simple in structure, the requirement of electrified railway high speed development has been satisfied in Installation and Debugging and easy to maintenance.

Technical solution of the present utility model: a kind of aluminum alloy Messenger Wire base, comprise Messenger Wire base body and holder wire clamp, Messenger Wire base body bottom is the horizontal pipe structure, be shaped on diagonal plane on its endoporus, be installed with the rim of a cup puller bolt, top is vertical circular tube structure, and the both sides of its stepped ramp type endoporus are shaped on strip groove; The holder wire clamp is the T-shape structure, and top is horizontally disposed Horizontal messenger wire clamp, and the bottom is vertical cylinder, and vertical cylindrical lower end is shaped on the spacing short wooden stake of boss; The vertical cylinder of holder wire clamp bottom is inserted in the stepped ramp type endoporus on Messenger Wire base body top and rotates to an angle and the spacing short wooden stake of boss is positioned at will ask wire clamp to be connected on the Messenger Wire base body under the step by strip groove.

Described Horizontal messenger wire clamp is made of wire clip body, catenary briquetting and binding bolt; The inboard of wire clip body, catenary briquetting all is shaped on wire casing, and the catenary briquetting is fixed on the top of wire clip body by binding bolt.

Be shaped on two symmetrical diagonal planves on the endoporus of described Messenger Wire base body bottom, be installed with two rim of a cup puller bolts.

The below of described Messenger Wire base body has hook, and the mouth of hook of hook has block.

The inboard of described wire clip body, catenary briquetting all is shaped on two wire casings, and binding bolt is between two wire casings.

Advantage that the utility model compared with prior art has and effect:

1, the utility model and Aluminium alloy arm for electric railway contact net as supporting part system matches have not only alleviated catenary load, and novelty simple in structure, and the requirement of electrified railway high speed development has been satisfied in Installation and Debugging and easy to maintenance.

2, the utility model contacts with the bracket pipe by diagonal plane, adopts the rim of a cup bolt to hold out against, and has improved part bonded assembly reliability.

Fig. 3 is the cross-sectional view of the vertical circular tube structure in the utility model holder wire clamp top.

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 Messenger Wire base comprises Messenger Wire base body 1 and holder wire clamp 2; Messenger Wire base body 1 bottom is the horizontal pipe structure, be shaped on two symmetrical diagonal planves 3 on its endoporus, be installed with two rim of a cup puller bolts 4, top is vertical circular tube structure, and the both sides of its stepped ramp type endoporus are shaped on and are 90 ° strip groove 5 with control position; Holder wire clamp 2 is the T-shape structure, and top is horizontally disposed Horizontal messenger wire clamp 6, and the bottom is vertical cylinder 7, and vertically the lower end of cylinder 7 is shaped on the spacing short wooden stake 8 of boss; The vertical cylinder 7 of holder wire clamp 2 bottoms is inserted in the stepped ramp type endoporus on Messenger Wire base body 1 top and rotates to an angle and the spacing short wooden stake 8 of boss is positioned at will ask wire clamp 2 to be connected on the Messenger Wire base body 1 under the step by strip groove 5.The below of Messenger Wire base body 1 has hook 13, and links up with 13 the mouth of hook and have block 14.

Horizontal messenger wire clamp 6 is made of wire clip body 9, catenary briquetting 10 and binding bolt 11; The inboard of wire clip body 9, catenary briquetting 10 all is shaped on two wire casings 12, and catenary briquetting 10 is fixed on the top of wire clip body 9 by binding bolt 11, and binding bolt 11 is between two wire casings 12.
