Description
Technical field
A kind of C type steel-aluminium composite conducting rail with holes, belongs to the equipment that power supply of urban orbit traffic is used.
Background technology
Before the utility model is made, in urban track traffic the 3rd rail and the 4th rail electric power system of prior art, the high-intensity steel-aluminium composite conducting rail of three-dimensional that for example patent No. is 201020281928.9, be only applicable to corrosion-resistant steel contact surface and be positioned at horizontal surface, be positioned at perpendicular and be not suitable for corrosion-resistant steel contact surface, its center of gravity is remote from aluminium flange of rail face.In the time that the stainless steel band of two L fonts is welded into one together with cylinder, welding heat makes aluminium section bar annealing, composite conductor rail of steel and aluminum stiffness degradation, and amount of deflection strengthens, and pantagraph current collector reduces in steel combined with aluminum track surface power taking quality.
Utility model content
It is remote from aluminium flange of rail face that the purpose of this utility model will overcome above-mentioned composite conductor rail of steel and aluminum center of gravity exactly, the shortcoming that amount of deflection is bigger than normal, and invention one is applicable to corrosion-resistant steel contact surface and is positioned at perpendicular, the large and little steel-aluminium composite conducting rail of amount of deflection of rigidity.
The technical scheme of the invention for solving the technical problem, its mainly in C type aluminium rail (2) left side and upper and lower round edge (7) bag carry out the C type corrosion-resistant steel (8) being welded by two J steel band of model (3), the inner side C type aluminium rail (2) of weld seam (5) is provided with the hole (4) of logical cooling water expansion tank, in the dead slot (6) of C type aluminium rail (2), can place middle connecting plate (9) or adapter plate (11), moving seat (13) can move or rotate in base (14).
Advantage of the present utility model:
1, little at maglev vehicle turn radius, sidewindering in the situation that angle is large pantagraph current collector on the utility model and locomotive has good moving contact matching characteristic.Brush life is long.
The rigidity that makes the welding of J steel band of model (3) can not reduce C type aluminium rail (2) of setting up of 2, leading to cooling water hole 4, composite conductor rail of steel and aluminum rectilinearity is good.
3, because moving seat (13) can rotate or move relative to base (14), the collimation of circuit bend place and magnetic suspension F rail is good.
4, the face area of C type aluminium rail (2) is large, and thermal diffusivity is good, and transmission current is large.
Brief description of the drawings
Fig. 1 is the drawing in side sectional elevation of C type steel-aluminium composite conducting rail with holes.
Fig. 2 is the drawing in side sectional elevation of the utility model center coupling place.
Fig. 3 is erection plan of the present utility model.
Detailed description of the invention
The embodiment of the utility model in is by reference to the accompanying drawings further described below: in Fig. 1, main body is C type aluminium rail 2, form C type composite conductor rail of steel and aluminum 1 with holes by C type aluminium rail 2 and C type corrosion-resistant steel 8, there are upper and lower two round edges 7 in the left side of C type aluminium rail 2, two J steel band of model 3 bags are carried out on round edge 7, after weld seam 5 is cooling, two J steel band of model 3 are tightly embraced to round edge 7, C type corrosion-resistant steel 8 is combined into one with C type aluminium rail 2.The C type aluminium rail 2 of weld seam 5 inner sides is provided with the hole 4 of logical cooling water expansion tank, screw is made in the two end tapping in hole 4, the water connection of screwing on, make the interior rapid flow cooling water expansion tank in hole 4, take away welding and pass to the waste heat on aluminium rail, C type aluminium rail 2 can not be annealed, keep the condition of heat treatment of its T6, rigidity is high, and amount of deflection is little, and composite conductor rail of steel and aluminum rectilinearity is good.The middle part of C type aluminium rail 2 is large-area dead slot 6, is used for placing middle connecting plate 9 or adapter plate 11.
In Fig. 2, dead slot 6 places that reach the adjacent C type composite conductor rail of steel and aluminum 1 with holes of 15m or 18m fill in the middle connecting plate 9 of long 400mm, in prefabricated hole, penetrate bolt 10, be aided with spring shim and nut etc. and form center coupling, machinery and electric on composite conductor rail of steel and aluminum 1 with holes adjacent C type is made to lontitudinal series, be aided with expansion pipe, composition the 3rd rail or the 4th rail supply lines such as anchor knot joint.
In Fig. 3, C type composite conductor rail of steel and aluminum 1 with holes is bolted on silica gel isolator 12 through adapter plate 11, silica gel isolator 12 other ends link with moving seat 13, moving seat 13 can be in the interior rotation of base 14 or movement, base 14 is arranged on the structure beam sidewall of Maglev Project or subway, adjust moving seat 13 positions with respect to base or angle, make the corrosion-resistant steel contact surface of C type composite conductor rail of steel and aluminum 1 with holes be positioned at predetermined locus, provide electric current to the pantagraph current collector of magnetic levitation vehicle or subway electric locomotive.
C type composite conductor rail of steel and aluminum 1 with holes in the time expanding with heat and contract with cold relatively adapter plate 11 move freely, make the steel-aluminium composite conducting rail can be bending.
