The contact rail is compounded with an aluminum alloy rail and a stainless steel band; the rain head contact surface of the aluminum alloy rail is coated with a layer of stainless steel bank; grooves and holes are arranged in the steel-aluminum contact rail; a support consists of a glass steel support at the lower part, a glass steel support in the middle and a glass steel support on the top; the glass steel support in the middle is connected with the glass steel support on the top, so as to clamp and suspend the steel-aluminum contact rail; the utility model has the advantages that the contact rail made of steel-aluminum material can effectively reduce the resistance rate, reduce the number of traction power stations in the power supply system, reduce the energy consumption of the contact rails in operation; the anti-rust and anti-corrosion performances are quite good; the weight of the steel-aluminum contact rail is light; the rail head is provided with grooves and holes, which can further reduce the weight, save material and is convenient for transportation and installation; the contact surface of the aluminum alloy rail is coated with a layer of stainless steel bank, which can greatly improve the wear resistance.
Description
Technical field
The utility model relates to the power supply of urban orbit traffic equipment technical field, belongs to a kind of and carries the steel-aluminum conductor rail of DC current to award the stream device to locomotive.
Background technology
At present, in the subway line of having opened at home, adopt contact rail to award having of stream device: Beijing Metro one line and loop wire, multiple eight lines of Beijing Metro, Tianjin Underground first stage of the project, its contact rail is arranged on the porcelain vase of ground support rail platform, the rail head contact surface upwards forms the top contact and awards stream mode, and the pantagraph current collector of vehicle contacts with end face on the contact rail and gets stream, this contact rail is the dead-soft steel contact rail, and protective cover is wooden " Γ " shape.
Above-mentioned dead-soft steel contact rail is awarded the stream device and is had following shortcoming:
1, because contact rail adopts low-carbon steel material to make, cause electrical resistivity big, the contact rail pressure drop is big, and power supply distance is little, need traction substation quantity more, and the contact rail waste of power is bigger.
2, dead-soft steel contact rail weight is big, and inconvenience is installed in transportation.
3, resistance to abrasion is relatively poor.
4, rust protection poor-performing.
Summary of the invention
The purpose of this utility model provides a kind of steel-aluminum conductor rail and awards the stream device, it can reduce electrical resistivity, can reduce the quantity of traction substation in the electric power system, the loss of contact rail energy when reducing operation, make things convenient for the construction and installation of contact rail, improve the resistance to abrasion of contact rail, strengthen stainless property.
For achieving the above object, the utility model is taked following design plan:
A kind ofly be used for urban track traffic and carry the steel-aluminum conductor rail of DC current to award the stream device to locomotive, form by contact rail, support and protective cover, it is characterized in that: described contact rail is by the aluminum alloy rail and stainless steel band is compound constitutes, and is coated with one deck stainless steel band on the rail head contact surface of aluminum alloy rail.
Be provided with slotted eye in the rail head of described aluminum alloy rail.
Described support is to be made of bottom glass steel bracket, middle part glass-felt plastic support, top glass steel bracket, this bottom glass steel bracket is L-shaped, the top of this L shaped bottom glass steel bracket is connected with middle part glass-felt plastic support, this middle part glass-felt plastic support is connected with the top glass steel bracket, and the steel-aluminum conductor rail clamping is hung.
On the top glass steel bracket, be provided with " ∩ " shape glass-felt plastic contact rail protective cover.
The utility model has the advantages that:
1, because contact rail by the aluminum alloy rail with stainless steel band is compound constitutes, can reduce electrical resistivity effectively, reduce the quantity of traction substation in the electric power system, and the loss of contact rail energy when reducing operation,
2, steel-aluminum conductor rail weight is little, and is provided with slotted eye again in contact rail, further expendable weight, and saving in material is convenient to transportation and is installed;
3, owing to be coated with one deck stainless steel band on the rail head contact surface of aluminum alloy rail, this corrosion-resistant steel zone face contacts with the vehicle pantagraph current collector and slides when getting stream, can improve resistance to abrasion greatly.
4, because contact rail adopts the compound rail of steel aluminium, rust protection better performances;
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Referring to shown in Figure 1: a kind ofly be used for urban track traffic and carry the steel-aluminum conductor rail of DC current to award the stream device to locomotive, its described contact rail constitutes by aluminum alloy rail 2 and stainless steel band 4 are compound, is coated with one deck stainless steel band 4 on rail head 9 contact surfaces of aluminum alloy rail 2.
For expendable weight and saving in material, in the rail head 9 of aluminum alloy rail 2, be provided with slotted eye 3.
Described support is to be made of bottom glass steel bracket 8, middle part glass-felt plastic support 7, top glass steel bracket 6, this bottom glass steel bracket 8 is L-shaped, be installed on the basis, the top of this L shaped bottom glass steel bracket 8 and middle part glass-felt plastic support 7 bolt togethers, this middle part glass-felt plastic support 7 and top glass steel bracket 6 bolt togethers hang steel-aluminum conductor rail 2 clampings.
" ∩ " shape glass-felt plastic contact rail protective cover 1 is installed on top glass steel bracket 6, and it can play the effect of safety precaution.
The glass-felt plastic support can play good insulation and supporting role; The stainless steel band 4 that coats on the rail head contact surface contacts with pantagraph current collector 5 and slides when getting stream, can improve the resistance to abrasion of contact rail; Employing can reduce electrical resistivity effectively by aluminum alloy rail 2 and the stainless steel band 4 compound steel-aluminum conductor rails that constitute, and can cut the quantity about 30% of traction substation in the electric power system; During operation, steel-aluminum conductor rail can reduce about 80,000 kWh of waste of power for annual every kilometer.
