AI Technical Summary

Technical Problem

Existing suspended rail transit systems have complex turnout structures, are difficult to maintain, and are costly. They also rely on complex mechanical linkages and control networks, which affect the reliability and economy of the system.

Method used

The switch point design adopts a fixed structure, including the first track, the switch section, and the second and third tracks. Track switching is achieved through V-shaped intersection and guide surface, eliminating the need for signal and control networks, and using simple fixed components to achieve track selection.

Benefits of technology

It reduces system operating costs, improves the safety and reliability of the track network, simplifies the maintenance process, supports flexible locomotive route planning, and reduces the requirements for installation accuracy and manufacturing difficulty.

Abstract

The utility model discloses a turnout structure of a track network of a small crown block. The turnout structure comprises a first track, a turnout section, a second track and a third track, the front end of the turnout section is connected to the tail end of the first track, and the second track and the third track are connected to the rear end of the turnout section. A first crossroad and a second crossroad are arranged in the crossroad section, the front ends of the first crossroad and the second crossroad intersect, and the rear ends of the first crossroad and the second crossroad are separated in a V shape; a rail opening is formed in the first rail, a second rail opening is formed in the second rail, and a third rail opening is formed in the third rail; the rail crossing is in butt joint with the front end intersection of the first fork and the second fork, the second rail crossing is in butt joint with the first fork, and the third rail crossing is in butt joint with the second fork. The width of the first turnout and the width of the second turnout of the turnout section are small, rail separation or rail combination is safer and more reliable, assistance of a complex reversing guide mechanism is not needed, and the follow-up operation and maintenance cost is further reduced.
