Abstract
The utility model discloses a transition elbow of a medium-low-speed magnetic suspension steel-aluminum composite contact rail system, comprising a double-limb transition elbow and a single-limb transition elbow corresponding to the double-limb transition elbow, wherein connecting parts of the double-limb transition elbow, the single-limb transition elbow and a steel-aluminum composite contact rail end head are provided with connecting ends which are the same as the cross section of a steel-aluminum composite contact rail in shape; electric connection connectors are used for respectively fixing the double-limb transition elbow and the single-limb transition elbow at the end heads of the steel-aluminum composite contact rail through bolts; the two groups of the electric connection connectors are connected through a flexible cable; a free end of the single-limb transition elbow is located in the middle of two limbs of a free end of the double-limb transition elbow; and the free ends of the double-limb transition elbow and the single-limb transition elbow are opposite to a steel-aluminum composite contact rail contact face and are warped in a circular arc shape. The transition elbow disclosed by the utility model has the advantages and the positive effects that the stability and the safety of a power supply system are extremely improved; a steel-aluminum composite contact rail insulating base is not subjected to a deflection outer force; a collecting shoe can more stably and safely pass; the transition elbow can effectively prevent a shoe colliding accident and the transition is smoother; and the connection is firmer and more stable.
Description
Technical field:
The utility model relates to the track traffic technical field, is specially the middle low speed magnetic suspension steel-aluminum conductor rail system transition elbow in the urban track traffic.
Background technology:
Plant the new direction of low speed magnetic suspension, have a extensive future as the urban track traffic development.Wherein a kind of power supply mode is that locomotive provides electric energy for adopting the steel-aluminum conductor rail system, and wiring arrangement is that the sidepiece contact is flowed.For satisfying the deflection requirement at track switch place in the magnetic suspension circuit, need to adopt the transition head bending device, realize mechanical transition and be electrically connected assurance system safe in operation.
The utility model content:
The technical matters that the utility model will solve is to provide to existing deficiency to be suitable for middle low speed magnetic suspension steel-aluminum conductor rail system transition elbow; Low speed magnetic suspension steel-aluminum conductor rail system track switch place in being applicable to; Making between itself and the contact rail has favorable mechanical and electric continued access, satisfies system's operating needs, guarantees seamlessly transitting of collector shoe; And the change in displacement can compensate track switch place contact rail and expand with heat and contract with cold the time, improve system safety and reliability.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Middle low speed magnetic suspension steel-aluminum conductor rail system transition elbow; Comprise two limb transition elbows and cooresponding single limb transition elbow with it; Two limb transition elbows are provided with the coupling end identical with the steel-aluminum conductor rail cross sectional shape with single limb transition elbow with junction, steel-aluminum conductor rail termination; Electric connecting joint is separately fixed at the termination of steel-aluminum conductor rail through bolt with two limb transition elbows and single limb transition elbow, and two groups of electric connecting joints connect through flexible cable.
The free end of said single limb transition elbow is positioned at two free-ended two limb midways location of limb transition elbow, and the free end of its pair limb transition elbow and single limb transition elbow is all towards the opposite direction of steel-aluminum conductor rail contact surface, circular arc warpage.
Advantage of the utility model and good effect:

Description of drawings:
Fig. 1, the utility model structural representation.
Fig. 2, the utility model structure are shown birds-eye view.
The specific embodiment:
Middle low speed magnetic suspension steel-aluminum conductor rail system transition elbow like Fig. 1, meaning shown in Figure 2; Comprise two limb transition elbows 1 and cooresponding single limb transition elbow 2 with it; Two limb transition elbows 1 are provided with and the identical coupling end of steel-aluminum conductor rail 5 cross sectional shapes with junction, steel-aluminum conductor rail 5 termination with single limb transition elbow 2; Electric connecting joint 3 is separately fixed at the termination of steel-aluminum conductor rail 5 through bolt with two limb transition elbows 1 and single limb transition elbow 2, and two groups of electric connecting joints 3 connect through flexible cable 4.The free end of said single limb transition elbow 2 is positioned at two limb transition elbow 1 free-ended two limb midways location, and the free end of its pair limb transition elbow 1 and single limb transition elbow 2 is all towards the opposite direction of steel-aluminum conductor rail 5 contact surfaces, circular arc warpage.
Method of application:
One, transition elbow self is installed
Two limb transition elbows are linked to each other with the two ends contact rail respectively through electric connecting joint with single limb transition elbow; Two cover electric connecting joints link to each other through flexible cable, and bolted also reaches the moment requirement.
Two, the transition elbow is with the action of track switch
In middle low speed magnetic suspension steel-aluminum conductor rail system, when circuit track switch deflects action, form a little angle between two limb transition elbows and the single limb transition elbow, collector shoe can smoothly pass through.
The above record is merely the embodiment that utilizes the utility model technology contents, and modification, variation that any people who is familiar with this technology uses the utility model to do all belong to the utility model scope that the utility model is advocated, and be not limited to embodiment.
