Abstract
The invention relates to a welding joint of steel and aluminum composite conductor rails, which belongs to power supply equipment for rail transportation. The welding joint is mainly characterized in that aluminum sections 7 and 8 of the adjacent steel and aluminum composite rails are connected at a common joint via a welding seam 5 and a fish plate 2. In addition, stainless steel portions 9 and 10 of the adjacent steel and aluminum composite rails are connected via a welding seam 4, so that the common joint is changed into the welding joint. Reliability of a power supply system is improved by the aid of the welding joint, gaps of the joint cannot be enlarged, electric sparks are avoided when a current collector runs through the welding joint, transition resistances of two ends of the joint are low, temperature rise is low, and electric energy is saved.
Description
Technical field
The present invention relates to a kind of weldering knot joint of steel-aluminium composite conducting rail, belong to the equipment of track traffic power supply usefulness.
Background technology
Before the present invention made, the 3rd rail electric power system of urban track traffic adopted steel-aluminium composite conducting rail in prior art, and for example patent is the steel-aluminium composite conducting rail of the antivibration of 200720150918.x, about every long 15mm.Two side waists in ordinary couplings during on-site installation are respectively put a fish plate; 4 bolts pass the hole of fish plate and the compound web of the rail of steel aluminium portion; The adjacent compound rail of steel aluminium and end bends, expansion pipe are linked up, electricly go up series connection, be combined into direct current supply line.The installation and connection method joint transition resistance of this simple dependence fish plate is bigger than normal; Temperature rise is higher; Long-term vibration back bolt and nut unclamps, and the probability that lost efficacy in the joint increases, and the slit of joint can increase in the progressive formation to winter in summer; Electro spark strengthened when shoegear passed through joint, and reliability reduces.
Summary of the invention
The objective of the invention is to overcome the compound rail of above-mentioned steel aluminium and rely on fish plate to install and the shortcoming of appearance merely, provide a kind of compound rail of steel aluminium joint transition resistance that makes little, temperature rise is low, the weldering knot joint that the gap of joint can not change.
The present invention solves the technical scheme that its problem adopts: except that doing the ordinary couplings with two fish plates; Further the corrosion-resistant steel with the compound rail of adjacent steel aluminium links up with the direct current argon tungsten-arc welding, and connects to one around two fish tail utmost points with the I-shape aluminium section bar of ac tungsten inert gases welding and the compound rail of left and right sides steel aluminium respectively.
Compared with present technology the present invention has the following advantages:
1, the present invention connects reliably the compound rail of steel aluminium: the ordinary couplings of fish plate improves an one magnitude with the parallelly connected system dependability that makes of weldering knot joint.Usually have 6 compound rails of steel aluminium and 1 expansion pipe and 2 end bends at least in each anchor section of steel-aluminium composite conducting rail, therefore produce 8 ordinary couplings at least, need, 32 cover bolt and nut fasteners with 16 fish plates.These series connected 8 weldering knot joints have become 9 parts into two parts after adopting the present invention, maybe movable part and assembly quantity reduce closely 9/10ths, so the system dependability of this anchor section has improved a nearly one magnitude again.
Can not increase by electro spark again when 2, the shoegear of electric locomotive is tied joint through the weldering of the present invention of the compound rail of steel aluminium, saves energy, the generation of no peak pulse electric current has improved galvanic quality of power supply.
3, the present invention can not be uneven the joint again, and no step has been eliminated the shoegear brush in the possibility that the ordinary couplings place often breaks, and has reduced the automotive servicing cost of upkeep, has improved the vehicle attendance rate.
4, the simple fish plate bonded assembly all-in resistance of leaning on of joint two ends transition resistance ratio of the present invention reduces more than 20%, thereby can save energy more than 20%.
5, the present invention makes the gap numerical value between the both ends of the surface of adjacent steel aluminium composite conducting rail constant, can not change with seasonal variation.The stability that has kept system's power supply.

The specific embodiment
Following the present invention combines the embodiment in the accompanying drawing to further describe:
In Fig. 1; The left side is the compound rail 1 of steel aluminium, and the right is the compound rail 6 of steel aluminium, and the centre is a fish plate 2; Fish plate 2 is arranged 4 cover bolt and nut fasteners 3 along line of centers; Have not 2 to arrange 4 cover bolt and nut fasteners 3 in the middle of compound rail 1 of left and right sides steel aluminium and 6 the bottom contact surface, in the middle of the compound rail 1 of left and right sides steel aluminium and 6 the bottom contact surface stainless steel weld joint 4 is arranged, around fish plate, have one to enclose aluminum alloy weld seam 5 along line of centers.Fish plate 2 and 4 cover bolt and nut fasteners are formed the ordinary couplings of the compound rail 1 of steel aluminium and 6.Stainless steel weld joint 4 becomes ordinary couplings into weldering with 5 of aluminum alloy weld seams and ties joint.Stainless steel weld joint 4 adopts the direct current argon tungsten-arc welding, and aluminum alloy weld seam 5 adopts ac tungsten inert gases welding, and weld seam 4 connects to one with the corrosion-resistant steel of the compound rail 1 of steel aluminium and 6, and weld seam 5 connects to one with the aluminium section bar of the compound rail 1 of steel aluminium and 6.The welding rod of weld seam 4 is stainless, and the welding rod of weld seam 5 is aluminum alloys.Weld seam 4 polishes flat and polishes at postwelding, guarantees that the brush of shoegear smoothly passes through in the joint.Weld seam 4 and 5 can eliminate because the distortion of the compound rail body of steel aluminium and the crooked unfairness that produces at the ordinary couplings place avoid the brush of shoegear to receive step to impact the destruction that causes.
In Fig. 2, bolt and nut fastener 3 is clamped in the waist of the compound rail of steel aluminium with left and right sides fish plate 2, constitutes ordinary couplings.5 of weld seams fuse fish plate 2 and the compound rail 6 of steel aluminium, and fish plate 2 and the compound rail 1 of steel aluminium are fused, and fish plate 2 finally makes steel aluminium compound rail 1 and 6 in the left and right sides fuse.Even lay down bolt and nut fastener 3 this moment, weldering knot joint also can keep compound rail 1 of steel aluminium and 6 being connected under the sustained vibration condition reliably.
In Fig. 3, the 7th, the aluminium alloy extrusions of the compound rail 1 of steel aluminium, the 8th, the aluminium alloy extrusions of the compound rail 6 of steel aluminium, the 9th, the stainless steel layer of the compound rail 1 of steel aluminium, the 10th, the stainless steel layer of the compound rail 6 of steel aluminium.Pass 2 cover bolts 3 on the aluminium alloy extrusions 7, also pass 2 cover bolts 3 on the aluminium alloy extrusions 8.Stainless steel weld joint 4 fuses the stainless steel layer of the compound rail 1 of left and right sides steel aluminum steel aluminium and 6.
The many compound rails of steel aluminium of series connection and several expansion pipes constitute an anchor section in two end bends, and the weldering knot joint of the compound rail of steel aluminium makes this anchor section become the one unit of the 3rd rail supply line, and weldering knot joint has guaranteed that the height of the 3rd rail supply line is reliable.
