Description
Technical field:
The utility model is relevant with contact nets in electrified railways.
Background technology:
Column, bracket and the registration arm of existing LY type integrated positioning contact nets in electrified railways is the pipe fittings by the carbon element steel, though have the intensity height, and characteristics such as load-carrying capacity is strong, easy-to-rust, service life is low, and is also not attractive in appearance.
The content of utility model:
The purpose of this utility model provides a kind of simple in structure, long service life, good looking appearance, LY type integrated positioning contact nets in electrified railways with low cost.
The utility model is achieved in that
The utility model LY type integrated positioning contact nets in electrified railways; pillar 1 and upper bed-plate 2; lower bottom base 3 connects; the strut insulator 5 of oblique wrist and arm 4 lower ends is connected with lower bottom base 3; the strut insulator 5 of one end of horizontal bracket 6 is connected with upper bed-plate 2; the other end of horizontal bracket and oblique wrist and arm links to each other; one end of registration arm 7 is connected with oblique wrist and arm 4; the other end is connected with oblique wrist and arm by registration arm messenger wire or pull bar 8; registration arm 7 is connected with steady arm 9; pillar 1; oblique wrist and arm 4; horizontal bracket 6; registration arm 7; pull bar 8 is a pipe, is made of the stainless steel protection pipe 11 of parent tube 10 and external diameter socket thereof.
The wall thickness of stainless steel protection pipe 11 is 0.3-0.8mm, and parent tube 9 is carbon steel tubings.
The utility model is compared with existing LY type integrated positioning contact nets in electrified railways, because that pipe fitting has is antirust, and the humidity environment, durable in use, the luxurious advantage such as attractive in appearance of appearance, the service life of having improved contact system greatly.Cost of manufacture is cheap.
Description of drawings:
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is one of A-A, B-B, C-C, D-D cutaway view of Fig. 1.
Fig. 3 be Fig. 1 A-A, B-B, C-C, D-D cutaway view two.
The specific embodiment:
Embodiment 1:
The utility model LY type integrated positioning contact nets in electrified railways are interconnected to constitute by column 1, horizontal bracket 6, oblique wrist and arm 4, registration arm 7, pull bar 8 and annex thereof.Shown in accompanying drawing 2,3, the stainless steel tube 11 that includes parent tube 10 and parent tube overcoat, above-mentioned parent tube 10 and stainless steel tube 11 can be selected common seamless tube or seamed pipe for use, parent tube can be selected carbon steel tubing for use, with seamless tube or carbon steel sheet through rolling the seamed pipe that is welded, the wall thickness of stainless steel tube 11 is 0.4-0.8mm, this effective stainless sheet steel rolls and is welded, be processed into stainless steel composite pipe through decorating polishing again, be made into the contact nets in electrified railways pipe fitting through each operation again, form through connection.
Embodiment 2:
With carbon steel or seamless tube, stainless steel tube derusts respectively, pickling, the dry processing.Again copper is inserted material and be plated on carbon steel pipe outside face and corrosion-resistant steel inside face, copper solder thickness is 0.05-1.0mm, after stainless steel tube 11 is linked in outside the carbon steel pipe 10, close with the common machine of moving with the hand drawing is bloated, again with common electro heat or induction heating equipment heating, heating-up temperature is 1100-1120 degree centigrade, be incubated 2-10 minute, make the copper solder of fusion be filled in gap between two pipes, be cooled to normal temperature subsequently, make the crystallization of copper solder form metallurgical articulamentum 12, make outer stainless steel composite pipe, manufacture the contact nets in electrified railways pipe through each operation again, each part connection forms contact system.
