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

Embodiment 1

[0087] Embodiment 1: With reference to the accompanying drawings, Figure 1 to Figure 11 It is a graphical illustration of the structure involved in Embodiment 1. In Embodiment 1, the right branching switch structure composed of the straight track and the right branch track is taken as an example, and the direction switching and route selection of the vehicle passing the switch are carried out. In detail, its direction switching and path selection relate to the overhead track switch switching system of the present invention.

[0088] Such as figure 1 As shown, the driving track 1 is a parallel double track installed in an overhead manner, and the load-carrying vehicle 10 runs on the driving track 1, and the car 11 carrying people or goods is suspended under the loading-carrying vehicle 10 through the boom 8, and the vehicle runs from left to right. Facing the turnout, you can choose to go straight or turn to the branch direction.

[0089]In the turnout part, that is, the int...

Embodiment 2

[0130] Embodiment 2: In the turnout part, an upright rail 14 can also be set above the track as a balance rail, and the side of the upright rail 14 is a track surface, which can provide lateral force for the load-carrying vehicle 10, so that the load-carrying vehicle 10 is kept balanced to pass the switch. Figure 12 It is a schematic diagram of the right branching switch of the second embodiment of the present invention, and the specific scheme is as follows.

[0131] Such as Figure 12 As shown, in the front of the switch, the center position above the driving track 1 is provided with an upright track 14 along the track direction, and the left and right sides of the upright track 14 are track surfaces. At the turnout position, the upright track is also gradually divided into the upright track straight section 141 and the upright track branch section 142 along with the turnout. The branch track of track 1 is deflected, and the vertical track branch section 142 ends after the...

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...
