Abstract
An inner guide rail switch and a rail transit system having same. The inner guide rail switch includes a fixed beam assembly and a movable beam assembly. Four passageways are defined by the fixed beam assembly. The movable beam assembly includes six movable beams. The four passageways are switched through combined movement of the six movable beams.
Claims15
An inner guide rail switch, comprising:
- a fixed beam assembly, wherein the fixed beam assembly comprises:
- four forks, wherein the four forks comprise a first fork, a second fork, a third fork, and a fourth fork, the four forks are respectively located at four corners of a quadrilateral, the first fork and the third fork are arranged diagonally, and the second fork and the fourth fork are arranged diagonally;
- and
- four passageways, wherein the four passageways comprise a first passageway, a second passageway, a third passageway, a fourth passageway, the first passageway connects the first fork and the second fork, the second passageway connects the first fork and the third fork, the third passageway connects the fourth fork and the second fork, and the fourth passageway connects the fourth fork and the third fork;
- and
- a movable beam assembly, wherein the movable beam assembly comprises:
- a first movable beam, wherein the first movable beam is movably arranged at the first fork and is configured to switch one of the first passageway and the second passageway to allow passage;
- a second movable beam, wherein the second movable beam is movably arranged at the second fork and is configured to switch one of the first passageway and the third passageway to allow passage;
- a third movable beam, wherein the third movable beam is movably arranged at the third fork and is configured to switch one of the second passageway and the fourth passageway to allow passage;
- a fourth movable beam, wherein the fourth movable beam is movably arranged at the fourth fork and is configured to switch one of the third passageway and the fourth passageway to allow passage;
- a fifth movable beam, wherein the fifth movable beam is movably arranged on one side of an intersection of the second passageway and the third passageway close to the first fork and the fourth fork, and is configured to switch one of the second passageway and the third passageway to allow passage;
- and
- a sixth movable beam, wherein the sixth movable beam is movably arranged on one side of the intersection of the second passageway and the third passageway close to the second fork and the third fork, and is configured to switch one of the second passageway and the third passageway to allow passage.
