Overhead rail transportation system and turnout system thereof

Abstract

The invention relates to an overhead rail transportation system and a turnout system thereof. The turnout system comprises an overhead travelling rail and a balance rail for maintaining vehicle balance above a turnout, the balance rail comprising two parts corresponding to a straight part and a branch part of the turnout, and a movable direction selection mechanism arranged on a load traveling crane running on the traveling rail. The turnout system further comprises an inclined pressing strip which is fixedly installed on a bearing structure of the traveling rail and arranged at a certain inclined angle with the rail direction. Along with forward running of the load traveling crane, the inclined pressing strip can gradually extrude a stress device on the direction selecting mechanism by means of the moving force of a vehicle body, and the stress device is forced to move or rotate to a preset position required for enabling the load traveling crane to smoothly pass through a turnout. Theoverhead rail transportation system adopting the turnout system can ensure that a vehicle can safely, reliably and quickly pass through the turnout, and meets the design requirement of 'fault 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 patent 201811476654.6 and patent 201320781521.6, a suspension track switch is also disclosed. They all adopt the design idea of ​​fixed track switch structure and 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
