An overhead rail transportation system and its turnout system

Abstract

The present invention relates to an overhead rail transport system and a turnout system thereof. The turnout system includes an overhead running track and a balance track above the turnout to maintain vehicle balance. The balance track includes two parts corresponding to the straight running part and the branch part of the turnout; A movable direction selection mechanism is arranged on the load-carrying vehicle running on the driving track; the turnout system also includes an inclined layer fixedly installed on the load-bearing structure of the driving track and arranged at a certain inclination angle with the direction of the track. Running ahead, the inclined bead can gradually squeeze the force-bearing device on the direction selection mechanism with the help of the force of the car body movement, forcing the force-bearing device to move or rotate to the point where the load-carrying vehicle can pass through the switch smoothly. desired preset position. The overhead rail transportation system using the turnout system can ensure that vehicles pass through the turnout safely, reliably and quickly, and meets the design requirements of "failure safety".

Description

technical field [0001] The invention belongs to the field of rail transportation, and in particular relates to an overhead rail transportation system and a turnout system thereof. Background technique [0002] Overhead rail transportation has many advantages that ground transportation cannot match, but it is rarely used in practice. The main reason is that the reliability of the turnout switching system is insufficient, it cannot adapt to the high-speed, high-density continuous traffic flow, and the speed of the vehicle curve is slow, which makes the whole system run slowly and the transportation capacity is relatively low. the value of. [0003] Patent No. 201520821367.X discloses a turnout for a suspension conveying device, which moves the principle similar to a train turnout to the air, and sets a movable connecting track on the track, which is driven by a driving device to swing, respectively forming a straight line or a lane change Two track states allow the trolley t...

AI Technical Summary

Problems solved by technology

The disadvantage is that the switching action is slow, which seriously restricts the speed and density of the vehicles. At the same time, the reliability is insufficient. If the connecting track is not in place due to a fault when the follow-up trolley arrives, the vehicle will be blocked if it is light, and it will hit the switch or even derail. ACCIDENT

[0004] In the patent 201811476654.6 and the patent 201320781521.6, a kind of suspended track turnout is also disclosed. They all adopt the design idea of ​​fixed track turnout structure and the movable direction switching device on the car body, but the disadvantage is the failure rate It is still relatively high, and there is a lack of effective safety protection measures when there is a failure. Basically, "a failure is an accident"

But because of different speeds, the centrifugal force generated in the curve is different, and the inclination angle required to provide centripetal force for passengers is also different. It adopts a fixed inclination angle, which cannot adapt to different speed requirements. If the design angle is different from the actual required angle Larger, there will also be problems with abnormal suspension

[0013] It can be seen that the existing technology cannot meet the needs of the development of overhead rail transportation in terms of turnout reliability and curve speed. A high-reliability, "fail-safe" turnout and curve that can adapt to high-speed, high-density continuous traffic flow Design becomes the key to the development of overhead rail transportation
