Description

Novel rail system and rail transit system

Technical Field

The utility model relates to a rail transit technical field, concretely relates to novel rail system of suspension type and rail transit system for individual rapid transit system.

Background

A track is one of the basic components of a track transportation system, and is mainly used for providing a traveling route for vehicles (such as trains, motor cars, ground falls, cars in personal rapid transit systems, and the like), and the vehicles are provided with traveling wheels so as to be matched with the track and move along the track.

In a rail transit system, the running of a vehicle along a rail is generally divided into double-rail running and single-rail running, wherein the double-rail running means that the vehicle runs forwards under the guidance of two parallel rails, and rail transit vehicles such as trains, motor cars and ground falls generally adopt double-rail running; the single-track running means that the vehicle runs along only one track, and compared with the double-track running, the cost of the track can be greatly reduced, but the running safety and stability of the vehicle are inferior to those of the double-track running, and the single-track running is more applied to a personal rapid transportation system.

In the prior art, the track for realizing double-track operation in the personal rapid transit system generally has some common disadvantages: 1. the existing track is not reasonable enough in structure, the vehicle cannot accurately guide in the actual running process along the track, the vehicle is easy to shake left and right in the track and is easy to generate intermittent or continuous collision with the side wall of the track, so that the vehicle vibration is aggravated, the noise is high, the vehicle speed is influenced, and even the vehicle can resonate in the track to influence the driving safety; for example, in a train active guiding type suspension single-track turnout system disclosed in chinese patent CN 108313068A, a track adopts a rectangular cavity with an open lower end, as shown in fig. 10, stabilizing wheels for guiding are respectively provided on both sides of a vehicle, and guiding is provided for the vehicle by matching the stabilizing wheels with the side walls of the track, however, a gap is usually present between the stabilizing wheels and the side walls of the track (as shown in fig. 4 in the patent), during the running process of the vehicle, the vehicle can sway left and right in the track, so that the stabilizing wheels can continuously collide with the side walls on both sides of the track, especially in a place with a continuous curve; in addition, the micro-rail switch structure disclosed in chinese patent CN207498750U, the switch reversing system of the suspended rail car disclosed in chinese patent CN 203996231U, and the switch reversing system of the suspended rail car disclosed in chinese patent CN 203558061U all have similar structures, and the above problems also exist. 2. In order to adapt to the existing track and provide guidance for the running of the vehicle, more stabilizing wheels (at least four) are generally required to be arranged on the existing vehicle, so that the structure of the whole vehicle is complex and the size of the whole vehicle is large, the size of the track is large, and the cost of the whole system is greatly increased. 3. Because the interaction force exists between the stabilizing wheels arranged on the side surfaces of the vehicle and the side walls of the track in the existing personal rapid transportation system, the requirements on the strength and the rigidity of the side walls of the track are high, and the side walls of the track are usually large in area, so that the cost of the whole track is greatly increased. 4. For example, in a turnout reversing system for realizing the trolley in a suspended track disclosed in chinese patent CN 203558061U, in a non-turnout area, an area close to the turnout, and an area in the turnout, the track structures are different, which causes the turnout structure to be complex, the cost to be high, and the problem of smooth butt joint to be considered in the installation trouble.
