Description

Cable-stayed type empty rail

Technical Field

The utility model belongs to the field of aerial trains, and particularly relates to a diagonal type aerial train track.

Background

An empty train, i.e., an abbreviation for air train, is a train that runs under an air track in a suspended manner. When the air train runs, the wheel disc for controlling running and direction is clamped in the track beam, and safety guarantee is sufficient. Compared with subway and light rail, the suspended air train has the features of low cost, high safety and reliability, etc.

The existing empty rail is usually supported in the air by arranging dense supporting beams on one side or two sides, so that the supporting beams are required to be arranged at intervals of a certain length in order to keep enough supporting force, and are mostly formed by pouring, the period of the pouring supporting beams is long, the cost is high, and when the empty rail with a longer span is built, the number of supporting beams is huge, so that the building time of the whole empty rail is long, and the cost is higher. When encountering a water surface with a large width, the support beams with dense empty trains cannot be constructed across the water surface, so that the existing empty trains cannot travel across the water surface, and the application range is small.

Disclosure of Invention

The empty rail 1 is directly pulled by using the main cable 3 and the cable 4 at the two ends of the supporting beam 2.

In this embodiment, the hollow rail 1 generates two symmetrical pulling forces on the support beam 2 in the direction of the main cable 3 when being stressed. The force on the left side of the support beam 2 can be divided into a horizontal leftward force and a vertical downward force; likewise, the right force can be divided into a horizontal rightward force and a vertical downward force; since these two forces are symmetrical, the horizontal left and horizontal right forces cancel each other out, and finally the force applied by the support beam 2 becomes two vertical downward forces, thereby transmitting the forces to the support beam bottom pier body.

In this embodiment, the main cable 3 and the branch cable 4 are both steel cables, and the bridge rail connected by the steel cables is integrally of the type of steel cable bridge, and the steel cable bridge has a certain elasticity compared with the conventional bridge (pier bridge); the existing pier-type supporting beam is replaced by a multi-span continuous elastic supporting beam 2. The bending moment of the beam body can be reduced, the building height is reduced, the number of the supporting beams 2 is less in requirement under the same length of the empty rail 1, the construction period of the supporting beams can be shortened, the structure weight is reduced, and materials are saved; simultaneously, the distance between the two support beams 2 on the empty row track 1 connected by the cable-stayed main cable 3 and the cable-stayed branch cable 4 can be further, the empty row track 1 such as river-crossing support can be realized, and the application range is wider. Compared with the existing empty rail, the inclined-pulling type empty rail has the advantages of shorter construction period, lower cost and wider application range.

In the present embodiment, as shown in fig. 4, the empty train running rail 1 is provided with a running cavity 11, a running gear 51 is provided on the top of the empty train car 5, and the running gear 51 is located in the running cavity 11.
